Use of isotopic sulfur to determine whitebark pine consumption by Yellowstone bears: A reassessment
Wildlife Society Bulletin, 2014 Use of naturally occurring stable isotopes to estimate assimilated diet of bears is one of the single greatest breakthroughs in nutritional ecology during the past 20 years. Previous research in the Greater Yellowstone Ecosystem (GYE), USA, established a

Validation of grizzly bear hair hormone profiles as a tool to monitor population demographics
The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.We measured 16 steroid and thyroid hormone concentrations in grizzly bear hair to predict sex, age class, and reproductive status. Models were highly accurate when predicting sex and age class and showed promise for assessing reproductive status. Results illustrate the potential for hair hormone profiles as non‐invasive population monitoring tools ...

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 585-597, February 2026.Abstract Estimating demographic rates of wild populations is critical to understanding their dynamics but can be challenging because large amounts of data are required, and parts of the life cycle of individuals may be unobserved. In numerous research programmes, capture–recapture (CR) data and biologging data are collected in parallel.

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

Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Wildlife tourist attractions (WTAs) can permit interactions between humans and wildlife that are detrimental to the animals’ welfare and species conservation. Social media portraying human–wildlife interactions could affect people's perceptions of their acceptability and desirability or stimulate demand for detrimental practices.

Climate Change Challenges Grey Wolf Resilience: Insights From Dental Microwear
Ecology Letters, Volume 29, Issue 2, February 2026.We investigate dietary plasticity in European grey wolves across interglacial periods using dental microwear texture analysis. Enhanced durophagy is associated with warm climates in both modern Polish and British Pleistocene wolves, indicating deep‐time behavioural flexibility.
