Climate Change, Resilience, Communication

Climate Change

Last week I listened to a webinar on climate change discussing findings of the draft report from the National Climate Assessment and Development Advisory Committee. Not much has changed from the year 2000 report, or the 2009 report. Well, a few changes: the science has improved, climate change is now being stated directly as a result of human activity and the report is more accessible and understandable to the public at large. The public that actually takes the time to read it, that is. How communities engage with science and government is a hot topic and will continue to be. The idea of citizen scientists was mentioned during the webinar and it has been in the news quite a bit. I’ve written about it here, but after today’s presentation, it triggered some new thinking and I pondered it a bit more in terms of climate change and planning resilient communities.

Engineering Community Resilience

With the recent round of floods and bush fires, particularly in Queensland, Victoria and Tasmania, and with Hurricane Sandy in the northeastern United States, I’ve been thinking more about how we engineer our communities and our transportation networks to withstand the dramatic stresses placed on them by natural disaster events such as these. In the face of extreme and more frequent weather events, we must begin to look at how we protect investments, not how do we avoid it, but how do we work with it once faced with the situation; how can our societal networks “adapt” to natural events. After hitting the power-on button after a disaster, how long does it take before we are up and running at full speed? It’s definitely not automatic and there is a lag time, but the mission should be to reduce that lag time as much as possible. We can do that through better planning of our communities, both urban and rural, from top to bottom.

Outdated Planning Manual

Jane Jacobs in her book, The Life and Death of Great American Cities, wrote the way we plan cities is outdated. Those thoughts were from the late 1950s; I wonder what she would think at the progress, or lack of, made now. While Ms. Jacobs was not an urban planner, she was an astute observer of city life. We have been planning to the same model for years, basing our land use and transportation plans on activity centers and primary uses as if these things were completely and utterly independent. When in reality, today more so than ever, emphasis should be placed on the connections between and among uses, from primary to tertiary uses and beyond. Emphasis should also be placed on addressing aging infrastructure. Outdated, roads, buildings, bridges, sidewalks, subways, telephone lines, sewers; all of these facets of modern society that once made life convenient can actually make life more inconvenient if technology does not keep up with the pace of increasing population and demand. It is a tough task to balance the needs of a community, of a nation, but attention to rediscovering and reengineering our primary uses to connect with present and future day society has to be part of this century’s new planning paradigm.

Community Communication

How does this national climate assessment report actually impact individuals? What does the public need to know? What does government and science need to tell people? I think ultimately that people have a desire to know what goes on in their communities; but they’re busy, they elect people and trust them to hire staff that will get the job done. And there is this mentality that they just want things to work and society grows cranky when things don’t work. Think about water pipes. An invisible zigzagging network buried underground. Much thought isn’t given them until they burst and the faucets run dry. Adding to the problem is that the public doesn’t understand how antiquated our infrastructure is, be it water pipes, bridges, or telephone lines. And public refusal to pay for a system’s upgrading because water has always been cheap just adds to the complex ability to make change happen. But I believe it can.

It all boils down to communication, at the basic, most simplistic level. That’s why it is critical governments do a better job at explaining and giving information to citizens when disasters strike AND details about the recovery and clean up process OR explaining why adaptation and mitigation measures need to be taken because not everyone understands why systems that date back to the 19^th century can’t handle pressures from the 21^st century. I can’t speak for other countries, but the “red tape” political pomp and circumstance on parade in the U.S. needs to shift toward a “green tape” common sense implementation attitude. Waiting over three months for recovery funds to come through after Hurricane Sandy hit inhibits community rebuilding and cuts to the psychological core of those affected.

Citizen Scientists Participation

Popularity of science among the masses is growing and should be engaged. So how can citizen scientists help? With all this talk of using ordinary citizens to collect data for large-scale research projects and as budgets tighten and staffs decrease, I think there will be a greater role for the community at large to help provide answers to research questions. To start with, our scientific organizations will need to use the cerebral thought process of corporations. The scenario is not that citizen scientists will be out there running amok with data; a trained scientist would no doubt be in charge. Like a project manager would in a big corporation, they would have people reporting to them, following the protocols, procedures and plans they have discussed to achieve a certain goal. I think this is the way science will have to move in order to stay somewhat viable as we attempt to solve the looming problems we face in the future.

Science, the community, government and private industry all need to be present and active partners communicating as we move forward designing our cities and countrysides in a certainly uncertain world. Policy choices should have been made 10 plus years ago as an attempt to deal with climate change, but hindsight is always 20/20. While this piece speaks mainly to the developed world, we shouldn’t ignore the rapid urbanization that is sweeping across the developing world, with many key urban issues not being fully explored. The municipal level has an opportunity to be a catalyst of change. As cities think about how to assess their risks and incorporate resiliency measures into their town planning, the population may actually be able to ebb and flow with climate disruptions.

Unknown Corals of the Deep

Corals are some of the most beautiful things to be found under the sea, blossoming in clusters like gardens off tropical coasts worldwide. Easily the grandest display is to be found in Australia with the Great Barrier Reef, and it seems that the reef may contain even more diversity than was once thought. The latest surveys have found Australian corals thriving at depths far greater than was ever before thought possible.

The Ribbon Reef lies near the Torres Strait at the edge of the Australian continental shelf, and certain parts of it are normally very difficult to get to. The University of Queensland’s Seaview Survey has been fastidiously charting the waters off the Australian coast with a diving robot, and were extremely fortunate to be able to use an unusually calm day to explore the windward side of the reef – normally a perilous exercise due to huge waves and cyclones. Exploring the depths of the reef, they found a huge surprise.

While deepwater corals are known in other parts of the world, their appearance in the waters here was a surprise. At a depth of 125 metres, in dark waters where very little sunlight ever reaches, they found corals. Corals which had only been recorded at depths of 70 metres previously, giving Ove Hoegh-Guldberg, the chief scientist of the team, reason to suspect that the finding may be able to give a deeper understanding of how coral reefs spawn and grow.

Hoegh-Guldberg is also quoted as saying, “What’s really cool is that these corals still have photosynthetic symbionts that supposedly still harvest the light,” which is especially remarkable because the waters in which these corals have been found are so inky and dark that human divers would have trouble seeing without artificial illumination. As well as photosynthesis, shallow water corals have reproductive cycles which are synchronised by the phases of the moon. With so little moonlight being able to penetrate to the depths at which these corals live, their spawning patterns are presently a complete mystery. It could be that these corals lead a lifestyle very different to their shallow water brethren.

The deepwater corals have also fared far better in the storms which have caused massive damage to the shallower parts of the reef. The team are now investigating how conditions such as ocean acidification and global warming are affecting these deeper reef dwellers.

The Seavew Survey has proven to be extremely successful so far, with a number of specimens which they’re currently investigating. Some species they’ve found are thought to be previously unknown in Australia, and others may even be newly discovered species. Hoegh-Guldberg summed up the team’s discoveries quite succinctly with the statement, “We are yet to discover many corners of the Earth.” Indeed we are. It’s exciting to know that there’s still more for us to discover about our planet!

Citizen Scientists

An interesting report released last week from the UK Environmental Observation Framework reveals the benefit of citizen scientists to governmental environmental organisations. The Nerc Centre for Ecology and Hydrology and the Natural History Museum in London, reviewed 234 projects – ranging from small surveys to large-scale programmes. The results found the involvement of volunteers offers “high value to research, policy and practice”.

Given the increasing number of complex scientific problems facing our communities, states and countries; coupled with the ever dwindling supply of cash on hand to fund research projects, it behooves governments to dial into this untapped source of volunteer environmental monitors and data collection specialists. People enjoy going to their local botanical gardens, taking the kids and grandkids to learn about the natural world surrounding them. A large majority of the population love their parks for taking walks and having picnics and for exercise. They want to see these lands, with the flora and fauna contained within them protected. People volunteer for things they believe in and causes they want to see sustained. That is the movement around science and the environment and why the citizen scientist movement is growing.

Scientists should be working with their governmental departments, or university outreach extension centers, to coordinate community science volunteer days. Measuring leaf litter in a forest, or tree ring growth, or monitoring a stream for the presence of certain harmful bacteria or toxic chemicals, or tallying the number of a threatened bird species are a few such projects that could be undertaken by community members. Scientists and their research teams and graduate assistants could customize their research projects with a component where they served as project managers working with the community to accomplish a piece of the data collection puzzle.

The Value – Minuses and Pluses

Of course, not every project will be appropriate for citizen scientists and a fair amount of training may have to be done, given the nature of the project. And the report touches on the fact that although the quality of the data collected by citizen scientists could be excellent, it may not be fully recognized by all researchers or policymakers. This seems to be an area that would require some policy work in setting up standards to ensure the legitimacy and recognition of such projects undertaken with contributions from citizen scientists. That minus shouldn’t be so hard to turn into a plus. Volunteer-collected data possesses a bevy of potential benefits. The use of smartphones continues to increase among consumers and with that comes development technologies in the form of apps that could play an easier role in data collection. A scientist could quite easily dispatch his volunteer army with marching orders to perform observations of the monarch butterfly (Danaus plexippus) over a 5-acre area of the park and have his/her data collection completed within a month’s time. And of course, the benefit that every bureaucrat or department chair loves to hear: it’s a cost-effective way to collect environmental data and could help meet the demands of increasing governmental reporting and compliance requirements.

Getting Started

I think it’s up to each and every one of us to identify the actions we can take that will help continue to make our environment habitable. And becoming involved in a citizen scientist program seems like an ideal way to start to make a difference in your community. Whether you are a scientist or a volunteer, the guide, produced alongside the report by the UK Environmental Observation Framework, is a great place to begin identifying and mapping out strategies for a collaborative citizen science project.

Great danger for the Great Barrier Reef

The Great Barrier Reef is easily among the world’s great natural wonders. A world heritage site since 1981, it’s known everywhere as a showcase for the beauty which Earth’s oceans are capable of producing. The world’s largest system of coral reefs, it’s actually composed of over 2900 smaller reefs, stretching along Australia’s coastline for 2600 kilometres. In modern times, it’s a major tourist attraction, and for a lot longer, it’s been part of the culture of Aboriginal Australian people. Unfortunately, the modern world hasn’t been kind to the Great Barrier Reef. A variety of environmental factors are conspiring to make the future for these Australian corals look rather bleak.

Alarmingly, in a study run by the US National Academy of Science earlier this year, it was found that over the past 27 years, the Great Barrier Reef has lost 50% of its corals. Half of the corals in the sites surveyed have disappeared since 1985, and it’s unlikely to be any better in any other locations. Alarmingly, two thirds of the corals lost, have been lost since 1998. Instead of slowing down, it seems that the damage is becoming more rapid over time.

The Great Barrier Reef is, in effect, the Amazon Basin of the Ocean. It’s a huge and bustling hub of biodiversity, rich with all manner of aquatic plant and animal species. Like a land-based rainforest, a vast number of self-contained ecosystems can be found within the reef, and many vulnerable and endangered species make their homes there. Species known to depend on the reef include turtles, crocodiles, dugongs, and sharks, as well as thousands of species of fish and invertebrate – including, of course, the corals themselves.

Climate conditions have been increasingly harrowing for the denizens of the reef, however. Inclement weather, including tropical cyclones, can cause severe damage to coral growths. Global warming is having a lethal effect on corals living near the edge of the reef, which are already at the high end of their temperature tolerance. The warm waters cause corals to expel their zooxanthellae (the symbiotic organisms with live with the coral, photosynthesising and providing around 90% of the coral’s energy requirements) resulting in coral bleaching and, eventually, death as the corals die of starvation. And then there’s the crown of thorns starfish, a natural predator of corals which has seen a sharp increase in numbers in recent years. While the starfish is actually in indigenous inhabitant of the reef, some suspect that overfishing of the starfish’s natural predators has contributed to their recent population explosion.

In light of the troubling findings, Australia’s Environment Minister, Tony Burke, said in an interview to ABC news that “We’ve all heard about damage to the reef over the years, but that 50 per cent figure, I think, rang a warning bell loud and clear for many people.” He also admitted that “there’s no doubt that there’s been a level of neglect for decades which, if it had been dealt with otherwise, we’d be in a much better situation now,” which is at least a sign that the problem is being given the recognition it deserves.

Australia has, in fact, put together its Reef Rescue programme over the past 5 years, spending millions of dollars on protecting the reef from human activities such as run off from land. While there’s not much which can be done about the cyclones which have done the most damage, work is also underway to cull the starfish which are currently the reef’s second biggest threat. Unfortunately, this is painstaking work, as each starfish has to be individually removed by hand. There’s simply no other suitable method.

The question then is how to safeguard the reef in the long term and hopefully help it to recover to its former glory? With one of the biggest future threats to the reef is global warming and the warmer waters which it causes, the method to be used to protect the reef is still under debate. Natalie Ban, who works for the ARC Centre of Excellence in Coral Reef Studies, is reported as saying, “In some areas summer is coming earlier and lasting longer; in others, both summers and winters are warmer than in the past.” Currently, there are two schools of thought on how to go about this – some argue that the most protection should be given to the areas which have suffered least, so that they can act as a haven for reef animals to help repopulate the area; while others would prefer the most vulnerable reef areas to receive the most protection.

Whatever means is chosen, it’s safe to say that Ban speaks for many of us in saying that she hopes for the best way of managing and protecting the reef during “what will undoubtedly be momentous environmental change.”

Breaking plates

What do Australia and India have in common? The answer is that they both share one of Earth’s tectonic plates – the drifting eggshell-like pieces of Earth’s crust, on which all of our planet’s continents sit. However, the Indo-Australian Plate is a slightly unusual one, and the two countries may not share it for much longer. Recent Earthquakes beneath the Indian Ocean suggest that this plate may be in the process of breaking in two.

We generally think of the surface of our planet as being fixed and unchanging. The reality though, is that this isn’t true. Earth’s continents and the tectonic plates which make them up are not fixed at all, drifting slowly across the planet’s surface. For instance, as you’re reading this, most of Africa is moving slowly to the North West and quietly tearing the beginnings of a new ocean into Earth’s surface. Meanwhile, Hawaii is moving at a speed of about 7cm per year which is about as fast as your fingernails are growing.

Of course, these movements are tiny, compared to the size of the Earth and its continents, but they still cause pressure to build up in Earth’s surface. Sometimes, seemingly without warning, that pressure continues to build up and– SNAP! Something in Earth’s crust cracks or ruptures. This jostles the plates and can cause earthquakes which rattle entire countries. Any places situated at the edges of tectonic plates are particularly prone to earthquake activity, with California and Japan being high profile examples. With enough quakes, however, dramatic changes can happen in Earth’s crust. On rare occasions, larger tectonic plates can sometimes break apart into smaller ones – and that’s exactly what’s happening somewhere beneath the Indian Ocean right now.

Breaking point – where the Indo-Australian plate is starting to rupture and split

April 11 this year saw two massive earthquakes strike west of Indonesia in quick succession, measuring 8.7 and 8.2 on the Richter scale. The result was a dramatic quadruple fault rupture in Earth’s crust (a rare event which is more or less exactly what it sounds like!) which caused shockwaves to reverberate around the whole planet. Around a week later quakes occurred across the world as the whole planet shivered in response.

Geologists, alarmed by what could have caused such a major event, took to analysing the quake. What they found was remarkable. Within roughly 160 seconds, four fault lines (existing fractures in the rock) tore apart under pressure. Remarkably though, this wasn’t at a plate boundary where this kind of activity is expected. It was right in the middle of the Indo-Australian plate. To the geologists looking at this data, this was like a smoking gun. A telltale sign that, as many had suspected, this particular tectonic plate is starting to fracture and split into two.

The Indo-Australian tectonic plate is already a bit of an oddity, being a rather thin and unusual shape compared with the others. The reason being that it was formed some 43 million years ago when two smaller plates (carrying the landmasses which would eventually become India and Australia) fused together. Since then though, it’s collided with the much more massive Eurasian plate. That collision has already caused enough pressure in Earth’s crust to create the Himalayas, one of the world’s most impressively tall mountain ranges. However, the Indo-Australian plate is still trying to move northwards. The western part of the plate is still pushing against the Himalayas, moving at about 3.7 centimetres per year, but the eastern part, including the entire continent of Australia, is moving at a much faster speed of around 5.6 centimetres per year. This is causing the whole tectonic plate to quite literally buckle, which is the root cause behind all of the quakes in the region over the past decade.

So what does this mean for anyone who happens to be living on that plate? Well, there are not going to be any sudden apocalyptic changes. After all, according to theories, this is not actually a new event – the Indo-Australian plate began to deform around 10 million years ago! Over millions of years, a new tectonic plate boundary will start to form under what is currently the Indian Ocean. This will cause thousands of similarly large earthquakes, but over such a length of time that they won’t be much more regular than they already are for those living around South-East Asia. All the same, planetary scientists are likely to continue watching this region with interest over the coming years.

Satellite view of the Himalayan mountain range – perhaps the most dramatic example of the force with which the Indo-Australian plate is pushing into the Eurasian plate!

So much science, so little time… – Photo credit, Leo Reynolds

Sigh, my photo caption sums it all up…

But here are the news stories that caught my eye and I hope you find them interesting as well. Maybe reading them will inspire your own work or to dig deeper for answers. In any case, enjoy!

This is one of my favorite topics because it offers up rampant debate on so many topics – society, education, cognition. You’re just going to have to read it for yourself.

This Is Your Brain on the Internet (Maybe) by Kyle Hill

So what is the Internet doing to our thinking? It is hard to say. Current research has a hard time keeping up with the break-neck pace of online culture, and only the more conventional mediums like television and newspapers have been evaluated in any rigorous sense.

Newspapers might be old school, but they do have an online media presence as well these days. This article was published in The Australian this week and concerns Australia’s own CSIRO. Genetically modified crops and foods have been a part of our collective diet for many years, whether or not some want to admit it. And they are here to stay. I am of the opinion that they play an important role in our food security given a number of ever changing variables in our environment. The usual characters are depicted in this piece and it will be interesting to follow this story and hear the response from CSIRO.

Scientists Wary of CSIRO GM Crop by Adam Cresswell

SCIENTISTS from three countries are warning a CSIRO-led push to make Australia the first nation in the world to introduce genetically modified wheat crops could pose a significant health threat to humans and other animals.

If you haven’t heard, NYC Mayor Mike Bloomberg has banned sugary soft drink sales in cups larger than 16 0z. in his efforts to personally tackle the obesity epidemic. I feel some disclaimers are in order: One, this story did appear on www.bloomberg.com, but you could have found it in a variety of online publications; and two, I serve on the Mayor’s Best Practices Partnership to identify strategies to combat childhood obesity. That being said, I find the details of the ban interesting as you can see in the quote below. I personally do not see the need for a a 32 oz. soda, but people who want their sugary fix will do some quick addition, carry more cans or bottles and walk to get more refills. Oh, how long must we wait for data on this?!

NYC Health Panel Backs Bloomberg Ban on Super-Size Sodas by Henry Goldman and Leslie Patton

Restaurants, movie theaters and other outlets have six months to comply or face a $200 fine each time there’s a violation, the health department said. The ban doesn’t apply to convenience stores and groceries that don’t act primarily as purveyors of prepared foods, which are regulated by New York state. The rules do allow consumers to buy as many of the smaller drinks as they want and to get refills.

To continue with the discussion on obesity, this is an interesting read which once again highlights the genetics vs. environment debate.

What’s the Main Cause of Obesity – Our Genes or the Environment? from ScienceDaily with resources from the BMJ (British Medical Journal)

The ongoing obesity epidemic is creating an unprecedented challenge for healthcare systems around the world, but what determines who gets fat?

And one last article that I thought was noteworthy, and a bit on the strange side by the title:

Chemists Develop Nose-Like Array to ‘Smell’ Cancer from ScienceDaily, findings appear in the current issue of the journal ACS Nano

The chemist says, “Smell ‘A’ generates a pattern in the nose, a unique set of activated receptors, and these are different for every smell we encounter. Smell ‘B’ has a different pattern. Your brain will instantly recognize each, even if the only time you ever smelled it was 40 years ago. In the same way, we can tune or teach our nanoparticle array to recognize many healthy tissues, so it can immediately recognize something that’s even a little bit ‘off,’ that is, very subtly different from normal. It’s like a ‘check engine’ light, and assigns a different pattern to each ‘wrong’ tissue. The sensitivity is exquisite, and very powerful.”

The rise in representation of non-human entities

It happened over ten years ago. Jimmy was incarcerated against his will, held in a cage, isolated, and denied the basic freedom he deserved. A Habeas Corpus request was put in on his behalf. A long ordeal involving lawyers and various international organisations.

It happened again last year, in San Diego USA, Tilikum, Katina, Kasatka, Ulises and Corky were all held captive. A lawsuit was filed at a federal court, declaring that they were being held as slaves in violation of the 13th Amendment to the US Constitution (the amendment that abolished slavery and involuntary servitude after the American Civil War).

One simple fact made these two cases unique — none of the subjects were human. Jimmy was a Great Ape. Tilikum, Katina, Kasatka, Ulises and Corky were all orcas. Those were not the first, and certainly not the last.

In 2005, a public prosecutor, Dr. Heron Santana, was involved in the landmark, bench-setting case that would provide the framework for all those that came after. As was the case with Jimmy, a Habeas Corpus was demanded for a female chimpanzee — Suíça, 23 years old, who had lived in a zoo for four years. What transpired made Suiça the first animal to be recognized as a subject in a court of law. In the end, the Habeas Corpus was approved — unfortunately, it was on the day after she was found dead in her cage.

Animal activism had always existed before then. But perhaps that was the spark the trend needed. Indeed, numerous examples now exist, including perhaps the most well known — the World Declaration on Great Primates, that proposes the extension of rights allowance in an equal way to all great primates: human beings, chimpanzees, bonobos, gorillas and orangutans, and identifying the three basic conditions to the relationship between humans and great primates — the right to life, individual freedom, and prohibition of torture.

With chimps and other great apes the difference is clear — “the only difference is that they do not talk

Arctic sea ice extent is plummeting to a likely new record low

The plot is from US National Snow and Ice Data Center (NSIDC) and shows the Arctic sea ice extent data for the melt seasons of 2007 and 2012 alongside the 1979-1999 average. 2007 was a record low year, but with about three weeks of melt season left it looks likely that 2012 will set a new and decisive record low. While individual years have a small degree of variation, overall the long term trend is quite markedly downwards.

There is a design and principle on which to earth functions.
The world needs to review its knowledge base, its functioning, in terms of energy to matter ratio that earth strives to maintain. Unless we awaken to understand the energy cycle in which we live and how earth is designed to sustain certain ratio of energy to matter, we are doomed for huge destruction. The increasing heat in the environment is creating disorder. Time earth gets to convert heat into biological mass is critically reduced. Consequently disorder is peaking stressing every ecological system and life in it. Noble Laureate James Lovelock has predicted destruction through increasing heat. We need to quickly evolve in our understanding of nature to survive on earth. Some organization or institution and the media should take up to awaken the world – read a small article and awaken and call the world’s attention – “Critical Thinking on Global Warming and Increasing Climate Catastrophes” by John Paily http://www.scribd.com/doc/101836445

Adapting Drinking Water Resources to the Impacts of Climate change in Europe – ADWICE Stakeholder Exchange Conference 2012

The ADWICE Stakeholder Conference will take place on 2 October 2012 in Brussels, Belgium. The event will offer a platform for dialogue for understanding the vulnerability of drinking water resources, water quality and water abstraction infrastructures to local, national and European decision makers, experts and researchers, water supplier and river basin authorities.

The one-day conference represents a valuable opportunity to share knowledge and experiences and to reflect on what kind of measures may be taken to mitigate or to adapt to it.

The one-day conference will present and discuss the draft results of the literature study conducted by a team led by BIO Intelligent Service, in collaboration with Cranfield University, Water Research Institute (IRSA), National Institute of Hydrology and Water Management (NIHWM) and ICLEI- Europe, for the European Commission (DG ENV). The event will offer a platform to share knowledge and experiences among scientific researchers, local government leaders, national policy-makers and representatives of European institutions and to receive feedback from stakeholder while gathering illustrations and best practices.

The morning session will provide inputs for further work while discussing the existing knowledge. The afternoon will be dedicated to highly interactive specific discussions with invited stakeholders and experts to explore different facets of this important topic in detail.

The conference is free of charge, though early registration is recommended to secure a place.

The Devil’s Technology

Biotechnology is rarely considered to be good for the environment. In fact, environmental campaigners frequently claim that genetically modified organisms represent a major threat to biodiversity and ecosystems. However, the study of the Tasmanian Devil Facial Tumour disease (DFTD) using genetic technologies is an example where biotechnology has been used to create a definite environmental benefit.

The Tasmanian Devil (Sarcophilius harrisi) is Australia’s largest surviving carnivore and endemic to the island of Tasmania. DFTD induces cancerous tumours on the face and inside the mouth of affected animals which die within months. The condition was first observed in north-eastern Tasmania in 1996. DFTD, like other cancers, is caused when mutations within a cell prompt it to switch from normal function into tumorous growth. Cancers are considered non-contagious as the tumour is contained within the body and is unable to spread to alternative hosts. Furthermore, the immune system of any alternative host would normally recognise any foreign tumour cells that managed to invade the body, and quickly kill them before the disease becomes established. However, the DFTD is exceptional in that it is readily transmitted between individuals of the same species, and this has resulted in the disease rapidly sweeping across the island and threatening the entire species with extinction.

In order to better understand the DFTD, an international team of scientists has sequenced the entire genome of the Tasmanian Devil and identified mutations underlying DFTD. The results were recently published in the scientific journal Cell. This biotechnological research surprisingly identified that none of the tumours originated in any of the hosts examined. Instead, they were able to trace them all back to one cancerous cell from within a female devil, possibly in the early 1990s. This radical and unusual tumour had developed the ability to jump from individual to individual in a uniquely contagious manner, so spreading the disease across the species.

The Tasmanina devil facial tumour.

Using the genetic sequence information, the researchers were able to discount the involvement of a virus in the transmission of DFTD. Instead they were able to identify a new and radical form of transmission. Devils often bite each other in the face during eating and feeding behaviours. During biting, fragments of tumour from an affected individual become implanted in an almost vampiric manner in a new and healthy individual.

The scientists also discovered that the DFTD tumour carries a mutation in a gene that plays a critical role in regulating the host’s immune reaction. From this, they concluded that the tumour cells are able to interfere with the host’s immune system immediately after implantation, The disrupted immune system is unable to kill the tumour, thereby ensuring the survival of the disease in the new individual.

The results of this study have provided valuable insight into the management of the DFTD and the conservation of the Tasmanian Devil. Because the condition is only transmitted through the bite from a diseased individual, the disease can be effectively controlled by quarantining healthy populations from diseased. The condition will then be naturally eliminated as diseased individuals die off from within the affected population. Such a policy has already been implemented with the Tasmanian Department of Primary Industries, Water and Environment who have been identifying and quarantining disease free populations within the island. Individuals from the protected population may then be re-introduced into the Tasmanian Devil’s former habitat once the disease threat has passed.

Despite the frequently cited threats that biotechnology poses to the environment, the application of gene sequencing technologies to the DFTD is an example of how biotechnology might be adopted to solve major environmental problems. In fact, the outcome of this gene sequencing project has contributed to a management plan that might yet save the Tasmanian Devil from extinction and conserve an important component of Australia’s unique biodiversity.

The extinction that is yet to come

By 2050 they will all be gone. The worst is yet to come.

The Amazon rainforest contains a wider variety of plant and animal life than any other biome in the world. The region in its entirety is home to roughly 2.5 million insect species, tens of thousands of plants, and some 2000 birds and mammals. To date, at least 40,000 plant species, 2000 fishes, 1000 birds, 427 mammals, 428 amphibians, and 378 reptiles have been scientifically classified. The Brazilian Amazon harbors roughly 40% of the world’s tropical forest and a significant proportion of global biodiversity.

The numbers speak for themselves. However, over the past few years what we’re seeing is a biodiversity crisis in slow-motion. Those numbers are at risk. The largest drivers of which being climate change and habitat loss by deforestation.

Habitat loss results in species extinction, but not immediately. When habitats shrink it may take several generations after an initial impact before the last individual of a species is gone. Extinction against the clock and in slow motion.

Visualising how this occurs and estimating the impact has always been a problem for researchers. The question now is — how many species are headed for extinction as a result of past and future deforestation?

New research published today in Science describes cutting-edge statistical tools used to devise a novel strategy to estimate the expected number of local species extinctions as a function of the extent of habitat loss.

Researchers made predictions on the extent of the extinction damage based on four possible scenarios — two in which all parties comply and respect current environmental law and protected area networks; and two which rely on strong reductions and eliminations in current deforestation rates. A reflection of recent pledges by the Brazilian government and potential reductions in deforestation proposed in 2009. What researchers describe is an estimation of something much more serious than previous estimates.

Spatial patterns in bird species and extinction debt in the Brazilian Amazon

Deforestation over the last three decades in some localities of the Amazon has already committed up to 8 species of amphibians, 10 species of mammals, and 20 species of birds to future extinction. Local regions will lose an average of nine vertebrate species and have a further 16 committed to extinction by 2050. The worst is yet to come it seems. More than 80% of local extinctions expected from historical deforestation have not yet happened.
