Carnivores without borders: management of transboundary populations when objectives differ

Using the recent case study of wolverines in Scandinavia as an example, Associate Editor, Kulbhushansingh Suryawanshi highlights why management initiatives for transboundary populations need to collaborate across borders – and what happens when they don’t. Globally, carnivore conservation has two very different objectives. First, to protect the population of the carnivore species from going extinct. Second, to mitigate the impact of the carnivore on the … Continue reading Carnivores without borders: management of transboundary populations when objectives differ

Video: Population density – a new method using remote cameras and radio collars

In this latest post, Jesse Whittington shares insights into new models for monitoring wildlife, including grizzly bears. Don’t forget to watch the video of some bears captured on camera! Whittington and colleagues’ Open Access article, Generalized spatial mark–resight models with an application to grizzly bears is available in the Journal of Applied Ecology. Wildlife managers around the world strive to estimate population abundance and the related … Continue reading Video: Population density – a new method using remote cameras and radio collars

African forest elephants are really slow breeders

In this post, Associate Editor Johan du Toit discusses new Policy Direction “Slow intrinsic growth rate in forest elephants indicates recovery from poaching will require decades” by Andrea Turkalo, Peter Wrege, and George Wittemyer, published today. Intrinsic population growth is related to body mass The rate at which a population grows (r) under ideal conditions with no resource limitation, disease, or predation, is governed by … Continue reading African forest elephants are really slow breeders

Not all herbivores are created equal – Characterizing population-level damage potential in migratory pests

In this post Gina Angelella discusses the recent paper from Sanford Eigenbrode and colleagues ‘Host-adapted aphid populations differ in their migratory patterns and capacity to colonize crops‘ When encountering a migratory insect such as a winged aphid, how confidently can one predict its origins and threat to crops? It is tricky enough to track the dispersal of a homogeneous species, but the addition of population-level … Continue reading Not all herbivores are created equal – Characterizing population-level damage potential in migratory pests

Energy production and wildlife: using syntheses for evidence-based decisions

In today’s post Chris Elphick (@ssts) discusses the recent review paper by Torre Hovick et al. and the importance of evidence-based syntheses for making informed decisions. This autumn, I saw my first Cape May warbler in the state where I live. Unfortunately, the sighting occurred when a colleague walked into my lab and handed me the corpse. Every year during migration, the ground around our … Continue reading Energy production and wildlife: using syntheses for evidence-based decisions

Disrupting herd migration boosts small carnivores

The important role of small carnivores (mesopredators) is being increasingly recognised in a variety of ecosystems, with negative impacts on biodiversity often being reported where mesopredator numbers are left unchecked. This generally occurs (and is studied) in systems where there have been changes in the numbers of big, apex predators. A new study by John-Andre Henden and colleagues from Norway published recently in Journal of … Continue reading Disrupting herd migration boosts small carnivores

People, predators and perceptions

This guest post was written by Kulbhushansingh Suryawanshi, who was awarded the 2013 Southwood Prize for his paper People, predators and perceptions: patterns of livestock depredation by snow leopards and wolves published with Yash Veer Bhatnagar, Stephen Redpath and Charudutt Mishra. Carnivores and pastoralist make very uneasy neighbours! Carnivores affect the livelihood of the pastoralist by preying on the livestock, and pastoralists kill the carnivores … Continue reading People, predators and perceptions

Pine Fiction: communicating research to a wider audience

Pine Fiction –a three minute stop-motion video by Alessio Mortelliti and Christina Thwaites. The aim of our video was to present the results of a relatively complex scientific study to a wider audience (to scientists and non-scientists) and to bring attention to the paper “Experimental evaluation shows limited influence of pine plantations on the connectivity of highly fragmented bird populations” by Alessio Mortelliti, Martin J. … Continue reading Pine Fiction: communicating research to a wider audience
