Bengaluru, 18 February 2017 – A new WCS study in India shows that three carnivores – tigers, leopards, and dholes (Asian wild dog) – seemingly in direct competition with one other, are living side by side with surprisingly little conflict.

Usually, big cats and wild canids live in different locations to avoid each other.

Yet in four relatively small reserves in India’s wildlife-rich Western Ghats region, WCS researchers have found that they are co-existing, despite competing for much of the same prey, including sambar deer, chital, and pigs.

Using dozens of non-invasive camera traps for sampling entire populations, rather than track a handful of individuals, the research team recorded some 2,500 images of the three predators in action.

The authors found that in reserves with an abundance of prey, dholes, which are active during the day, did not come in much contact with the more nocturnal tigers and leopards. But in Bhadra Reserve where prey was scarcer, their active times overlapped, yet dholes still managed to avoid the big cats. In Nagarahole, a park teeming with all three carnivores and their prey, leopards actively to avoid tigers.

Overall, the authors say that these carnivores have developed smart adaptations to coexist, even while they exploit the same prey base. However, these mechanisms vary depending on density of prey resources and possibly other habitat features.

Said Ullas Karanth, WCS Director for Science in Asia and lead author of the study: “Tigers, leopards, and dholes are doing a delicate dance in these protected areas, and all are manging to survive. We were surprised to see how each species has remarkably different adaptations to prey on different prey sizes, use different habitat types and be active at different times. Because of small and isolated nature of these high prey densities in these reserves, such adaptions are helpful for conservationists trying to save all three.”

Both tigers and dholes are classified as Endangered by IUCN; leopards are considered Vulnerable.

Understanding these separate yet overlapping species’ needs is critical to managing predators and prey in small reserves, which is increasingly the scenario of the future.  The authors say that by managing populations of flagship predators, like tigers, carefully overall biodiversity can also be conserved.

The study titled “Spatio-temporal interactions facilitate large carnivore sympatry across a resource gradient” authored by Dr. Ullas Karanth, Mr. Arjun Srivathsa, Dr. Divya Vasudev, Ms. Mahi Puri, Dr. Ravishankar Parameshwaran and Dr. Samba Kumar, appeared in the journal Proceedings of the Royal Society of London B: Biological Sciences in February 2017.

This research was supported by the Department of Biotechnology and Department of Science and Technology, Government of India; The Forest Department and Department of Science and Technology, Government of Karnataka; and the Liz Claiborne and Art Ortenberg Foundation.

PRESS RELEASE

  • Landscape connectivity critical for elephant conservation

  • Sites important for elephant connectivity often faced with human–elephant conflict

  • Barrier-centric conflict mitigation that come with substantial monetary costs can also come at the cost of elephant conservation

  • Minimising conflict without impinging on elephant connectivity is the need of the hour

 

BENGALURU, JANUARY 9 2017 – Scientists from Wildlife Conservation Society (WCS), India Program are calling for a re-think on conservation strategies for threatened and wide-ranging large mammal species.

In an article published in the international journal Frontiers in Ecology and Evolution, Dr. Varun R. Goswami and Dr. Divya Vasudev, conservation biologists at WCS India, highlight the need to balance multiple conservation needs and opportunities in large landscapes.

“Asian elephant conservation provides the perfect example”, says Dr. Goswami who heads the elephant program for WCS India. “Elephant survival in heterogeneous landscapes rests on their ability to move among habitats in search of food and space,” he elaborated. But this movement often brings elephants into contact and potential conflict with people, especially in densely populated countries like India.

A typical response to conflict is to prevent elephants from coming out of forests through fences and trenches. “But this strategy has a direct negative impact on connectivity, and as a result, on elephant persistence”, says connectivity expert Dr. Vasudev.

While some say that demarcated corridors will not be fenced, Dr. Vasudev cautions, “animals don’t always move through corridors that people demarcate, rather they use routes they view as least threatening. Corridors are of course important, but we still have a way to go in knowing where animals move, what stops dispersal, and which areas are most critical for maintaining connectivity”.

This debate becomes highly pertinent in light of the railway fences coming up around some of India’s most important forests. The cost of these fences reportedly runs to more than Rs. 1 crore per km. “These fences come at huge monetary and manpower costs, and before putting them up, we need to think hard about where we place them” Dr. Goswami emphasized. “It is critical that we minimize human–elephant conflict, but while simultaneously thinking about elephant movement needs between habitats.”

“Endangered species—elephants, tigers, gibbons—are more and more present in fragmented landscapes. Conserving them in these landscapes means that we need to have science-based policy, long-term vision, and incorporate diverse challenges and opportunities”, says Dr. Vasudev.

The article titled ‘Triage of conservation needs: the juxtaposition of conflict mitigation and connectivity considerations in heterogeneous, human-dominated landscapes’ authored by Dr. Goswami and Dr. Vasudev appeared in the journal Frontiers in Ecology and Evolution, and can be accessed at: https://doi.org/10.3389/fevo.2016.00144

  • India’s first workshop on Statistical Ecology conducted in collaboration by Indian Statistical Institute-Bangalore and Wildlife Conservation Society’s India Program

  • Inter-disciplinary team of leading experts in statistics, ecology and conservation meet to explore cutting edge methods of gathering and analysing ecological data

  • Over 60 researchers from institutions from India, USA, Malaysia, Myanmar and Australia attend the workshop on “Statistical Ecology and Related Topics” at the Indian Statistical Institute-Bangalore Centre, during December 8-11, 2016

Bengaluru, 30 December, 2016 : Global advances in statistical methodologies which direct the gathering and analysing of data in fields as diverse as economics, epidemiology and weather forecasting are rapidly being developed by Indian researchers. However, in the field of ecology, particularly conservation monitoring, India has made little progress, in spite of being home to both world class mathematical and statistical knowledge as well as many talented ecologists and conservationists who have made their mark globally.

 

To bridge this gap between statistics and ecology, a group of globally recognized experts from both these fields were brought together to conduct the first such workshop on “Statistical Ecology and Related Topics” in Bangalore between December 8-11, 2016. The workshop was jointly organized by Indian Statistical Institute (ISI)-Bangalore Centre and Wildlife Conservation Society’s (WCS) India Program and attracted the participation of 60 researchers from multiple institutions in India, USA, Australia, Malaysia and Myanmar.

 

The workshop elucidated examples of advanced statistical applications to research problems in diverse areas of animal ecology, plant ecology, environmental genetics, epidemiology and wildlife monitoring. Advanced quantitative approaches covered included Likelihood-based and Bayesian inference, Markov-Chain Monte Carlo and Boot-strapping methods. The application of such techniques with appropriate statistical models to sample and estimate animal/plant distributions and abundance across space and time were explained through lectures and panel sessions led by several experts in statistics and ecology.

 

They included Dr. Robert Dorazio (US Geological Survey) and Prof. Sudipto Banerjee (University of California, Los Angeles), Prof. Mohan Delampady (Indian Statistical Institute), Prof. Vidyasagar Padmawar (Indian Statistical Institute) and Prof. Arnab Chakraborty (Indian Statistical Institute), Dr. Ullas Karanth (Wildlife Conservation Society and National Centre for Biological Sciences) and Dr. Arjun Gopalaswamy (Oxford University and Indian Statistical Institute).

 

The workshop focused on the full scientific process – from asking ecological questions to building statistical models that tackle these questions based on sound data. It covered nuances of statistical computation techniques, and, issues of wildlife population assessment as well as societal challenges to advancing the field of statistical ecology in India.

 

Dr. Ullas Karanth (Wildlife Conservation Society and National Centre for Biological Sciences), who handled two sessions on the monitoring and assessments of wildlife populations says, “It is regrettable that in spite of recent advances in statistical ecology, which can benefit wildlife conservation hugely, their rapid absorption is often blocked by Governmental constraints as shown by our national ‘tiger census’. This situation can be changed only with a wider and genuine involvement of qualified scientists from outside the official structures that manage wildlife in India”.

 

Says Dr. Arjun Gopalaswamy (Oxford University and Indian Statistical Institute), “The workshop was a great success because it brought together the right experts to raise good questions and explain the best methods to address them. This is a new area at the interface of ecology and statistics, which the participants found exciting and useful, I think”.

 

Professor Mohan Delampady from Indian Statistical Institute-Bangalore Centre says, “Indian Statistical Institute has a deep tradition, going back all the way to its founder Prof. Mahalanobis, of bringing the best of statistics and science together to solve the country’s problems, as it pursues its developmental goals. I hope this workshop will take that tradition forward into the new and highly relevant areas of ecology and conservation”

 

Dr. Robert Dorazio from the United States Geological Survey, says – “I was gratified at the high caliber and intense interest and enthusiasm of most workshop participants. It was a privilege to see statistical ecology advancing in India, which is one among the worlds most biologically rich nations”.

 

One of the participants, Dr. Ravishankar Parameshwaran says that the workshop provided a clear overview of ecological concepts. He says, “the workshop was challenging and exciting, the various topics discussed were easy to follow”.

Western Ghats Coffee Plantations Sustain High Bird Diversity in India

  • One of largest scientific assessments of tropical birds in the world, covering an area of 30,000 sq. km in Karnataka
  • Coffee, rubber and areca agroforests found to support 204 bird species, including 13 endemic birds of the Western Ghats
  • Coffee is richer in birds than areca and rubber, but all three agroforests are important for bird conservation in the Ghats
  • Tree cover is an important factor associated with higher bird species richness

Bengaluru, 24 September 2016: Globally, it is recognized that agricultural plantations and agroforests host a diversity of insects, amphibians, reptiles, mammals, birds and bats. In India’s Western Ghats, small and isolated protected areas are embedded in a matrix of multiple land-uses, most of which include agroforests. These agroforests are being increasingly recognized for their supplementary role in conserving wildlife.

This study evaluated bird diversity in areca, coffee and rubber agroforests, which are the most widely grown plantation crops in Karnataka’s Western Ghats.

 

The study, “Producing Diversity: Agroforests Sustain Avian Richness and Abundance in India’s Western Ghats,” appears in the current edition of Frontiers in Ecology and Evolution. Dr. Krithi K. Karanth (Associate Conservation Scientist, WCS-NY), lead author of the paper stated that “this effort involved intensive research in 187 plantations covering an area of 30,000 km2 – taking the team two years to complete. This is one of most comprehensive assessments of tropical bird diversity outside protected areas conducted in the world”.

 

The study finds that coffee agroforests support higher diversity and abundance birds when compared to areca and rubber, and found 13 endemic bird species. “Large-bodied frugivores like pigeons and hornbills are found in much higher densities in coffee. These birds play a very important role of seed-dispersal and maintenance of forest trees in the region”, says Shashank Dalvi who is a co-author of the paper and one of the leading ornithologists in the country.

 

The scientists found a clear positive association of tree density and tree cover in the surrounding areas, on bird diversity. Changing agricultural practices that open-up shade tree canopy or switching from coffee and areca to monoculture crops such as rubber can seriously damage the ability of these agroforests to support birds.

 

Agroforests of the Western Ghats play a critical supplementary role in conserving India’s birds. The authors note that the biodiversity value of agroforests discovered in the study should be incorporated into future planning and policy decisions to facilitate and promote long-term biodiversity conservation. These scientific results should be integrated with policy and markets so that biodiversity rich agroforests can be incentivized to promote sustainable farming practices that enhance birds in coffee, rubber and areca agroforests.

 

The authors of this study are Dr. Krithi Karanth, Vishnupriya Sankararaman, Shashank Dalvi, Arjun Srivathsa, Dr. Ravishankar Parameshwaran, Sushma Sharma, Dr. Paul Robbins, Dr. Ashwini Chhatre. This study was a collaboration by scientists from Wildlife Conservation Society (WCS), Centre for Wildlife Studies, University of Wisconsin (Madison), University of Illinois (Urbana-Champaign) and Indian School of Business (Hyderabad) and supported by the National Science Foundation (USA).

6 months, 1 week ago Comments Off on Landscape Connectivity Affects Genes to Communities

  • Connectivity between forest fragments is critical for avoiding extinction
  • A review of 370 scientific articles reveals that isolation of habitats or wildlife populations almost inevitably has negative impacts such as high mortality, low reproduction and local extinctions. 
  • Studies on the impacts of connectivity are sadly lacking in India. 
  • Scientists recommend more objective-based assessments to understand impacts of landscape connectivity

Bengaluru, 18 August 2016: Wild animals disperse or move between isolated forest fragments to maintain linkages or connectivity. But in a fast changing world, these linkages are slowly eroding.

“Across species, and across geographies, whether you are looking at genetic material, population growth rates, or communities, the answer is the same – as connectivity erodes, species lose out,” says Dr. Robert Fletcher, lead author of the study and Associate Professor at the Department of Wildlife Ecology and Conservation, University of Florida.

As connectivity is lost, genetic variability declines. Consequently, animals are less able to adapt to new environments, more prone to diseases, and can suffer from low survival and reproduction. Ultimately, local extinctions may occur, leaving behind depauperate animal communities and collapsing ecological systems.

“In India, Protected Area sizes are small, and landscapes are rapidly changing”, says Dr. Divya Vasudev, Wildlife Conservation Society (India). “Still we have little knowledge of the consequences on our biodiversity”.

Even for a species that is well studied, like the tiger, we are only now acquiring empirical knowledge on the role that connectivity plays in preventing its extinction. Potentially dispersing tigers have been removed into captivity from conservation landscapes.

The country is immersed in debates and court cases on the construction of National Highways across recognized tiger corridors. “If we had a better handle on the consequences of disrupting connectivity between tiger populations, maybe it would prompt more effective mitigative action”,  adds Dr. Vasudev.

Connectivity research provides practical insights to specific negative implications of habitat fragmentation on wildlife.

The authors recommend focusing on estimating connectivity effects, capturing movement processes, accounting for uncertainty and isolating connectivity effects relative to others. This will enable immediate on ground action needed to ensure that functional linkages are maintained between habitat patches, and further fragmentation is immediately and effectively curtailed.

The paper titled ‘Divergent perspectives on landscape connectivity reveal consistent effects from genes to communities’ was published in the journal Current Landscape Ecology Reports last month. Authors include Robert J. Fletcher, Noah S Burrell, Brian E. Reichert, Divya Vasudev, and James D. Austin.

New paper warns of imminent extinction crisis for largest wild animal species

Study Link:http://bioscience.oxfordjournals.org/content/early/2016/07/25/biosci.biw092

doi: 10.1093/biosci/biw092

John Delaney – 718-220-3275jdelaney@wcs.org

New York (July 27, 2016) – A team of conservation biologists is calling for a worldwide strategy to prevent the unthinkable: the extinction of the world’s largest mammal species.

In a public declaration published in today’s edition of the journal BioScience, a group of more than 40 conservation scientists and other experts are calling for a coordinated global plan to prevent the world’s “megafauna” from sliding into oblivion. 

 

Among the threats cited by the group as drivers of this mass extinction are illegal hunting, deforestation and habitat loss, the expansion of agriculture and livestock into wildlife areas, and the growth of human populations.

 

“The more I look at the trends facing the world’s largest terrestrial mammals, the more concerned I am we could lose these animals just as science is discovering how important they are to ecosystems and to the services they provide for people,” said Dr. William Ripple, professor of ecology at Oregon State University and lead author of the study.

 

Ripple worked with other authors on the study to examine population trends of many species, including many of the most well-known, charismatic species such as elephants, rhinos, gorillas, and big cats that are now threatened with extinction. 

Approximately 59 percent of the world’s biggest mammalian carnivore species—including the tiger— and 60 percent of the largest herbivores are now listed on the International Union for Conservation of Nature’s Red List of Threatened Species as threatened with extinction.

“Perhaps the biggest threat for many species is direct hunting driven by a demand for meat, pets, and body parts for traditional medicines and ornaments,” Dr. Elizabeth Bennett, WCS’s Vice President of Species Conservation and a co-author on the study. “Only a massive commitment from the international community will stop this rampant destruction of so many animal populations.”

 

All of these large species play critical roles in their ecosystems. Species at risk include elephants, that provide a suite of vital ecosystem services as ecological engineers, dispersing seeds and nutrients across vast areas. “The loss of elephants in the forests of Central Africa is increasingly damaging the function of the region’s most important ecosystems,” said WCS Conservation Scientist Dr. Fiona Maisels, one of the study’s co-authors. “We’re only beginning to understand how vital these keystone species are to the health of rainforests and other species that inhabit them.” 

Human–wildlife conflict is a serious concurrent threat for many species. “With simultaneous loss of wildlife habitat and expansion of human populations and agriculture, negative interactions between people and wildlife are bound to rise,” said WCS India Scientist Dr. Varun R. Goswami, also a co-author on the study. “For wide-ranging megafauna like elephants and tigers, we need landscape-scale conservation strategies, taking into account the increasing interface between wildlife and people.” 

 

Some megafauna face the threat of obscurity. The loss of elephants worldwide to poachers in pursuit of ivory is well-known and is the focus of extensive efforts to shut down this trade, but the study authors point out that many species are at risk from many similar threats but are so poorly known that effective conservation efforts to save them are difficult. 

 

The paper includes a 13-part declaration that highlights the need to acknowledge the threatened status of many large mammals and the vital ecological roles they play. The declaration also cites the importance of integrating the efforts of scientists and funding agencies in developing countries where many species occur; the need for a new global framework to conserve megafauna; and the moral obligation of saving the world’s biggest mammal species.
