The impact of climate change on the structure of Pleistocene mammoth steppe food webs

, 2013
Species interactions shape predator-prey networks, impacting community structure and, potentially, ecological dynamics. It is likely that global climatic perturbations that occur over long periods of time have a significant impact on species interactions

Genome characterization and population genetic structure of the zoonotic pathogen, streptococcus canis [PDF]

, 2012
Background - Streptococcus canis is an important opportunistic pathogen of dogs and cats that can also infect a wide range of additional mammals including cows where it can cause mastitis. It is also an emerging human pathogen.

Understanding contingency in wolf‐mediated livestock predation across a mosaic of land uses: An agent‐based modelling approach

People and Nature, EarlyView.
Abstract The return of grey wolves to multi‐use landscapes in North America and Europe raises concerns over accompanying risks of livestock predation. While local‐level risk factors have received attention, it is difficult to explore the role that landscape‐scale variables, such as landscape connectivity, play in driving livestock losses.

Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau

People and Nature, EarlyView.
Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

Pest Management Science, EarlyView.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

Post-Conflict Affiliative Behaviors Towards Humans in Domestic Dogs (Canis familiaris) [PDF]

, 2016
Social species need conflict-resolution mechanisms to maintain group cohesion and diminish aggression. Reconciliation (affiliative contact between opponents) and consolation (affiliative contact between the victim and an uninvolved third party) have been

Cameras do not always take a full picture: wolf activity patterns revealed by accelerometers versus road‐positioned camera traps

Remote Sensing in Ecology and Conservation, EarlyView.
Camera traps have become an increasingly popular non‐invasive alternative to animal‐attached devices for studying wildlife behaviour. This study compared wolf (Canis lupus) activity patterns derived from collar accelerometers and road‐positioned camera traps and revealed strong overall agreement but also important seasonal and diel mismatches between ...

Fatal babesiosis in a free-ranging iberian wolf co-infected with Hepatozoon canis and Leishmania infantum: Epidemiological implications for the cantabrian wolf population

International Journal for Parasitology: Parasites and Wildlife
Health surveillance of large carnivores, such as the Iberian wolf (Canis lupus signatus), allows the early detection of emerging and established pathogens in natural environments, due to their position in the top of the food chain.

Knee height is often right: evaluating device height effects on camera trapping rate

Remote Sensing in Ecology and Conservation, EarlyView.
Camera trap deployment height can introduce systematic biases in detection trapping rates across species of different body sizes. Combining 172 paired sampling points in five experiments across Europe, North America and Africa, our results show that low cameras significantly increase detections of small‐ and medium‐sized species, whereas high cameras ...
