When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

Oikos, Volume 2026, Issue 8, August 2026.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, Volume 95, Issue 8, Page 1298-1310, August 2026.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Using Ongoing Wildlife Surveillance Programs to Monitor Antibiotic Resistant Bacteria in the Environment

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Screening of ESBL‐, pAmpC‐ and carbapenemase‐producing Escherichia coli among Swedish wildlife demonstrated a low occurrence of antibiotic resistance in wild animals. Only two ESBL/pAmpC‐producers were detected in red foxes originating from highly populated areas.

Integrating traditional practices, livelihoods, and conservation with Indigenous‐led furbearer camera trapping

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Contemporary conservation goals have a greater chance of success when practitioners collaborate with Indigenous communities. The importance of such collaborations has spurred calls by Western and Indigenous researchers to engage in equitable coproduction of ecological research that integrates multiple ways of knowing.

The impacts of different visitor management strategies on wildlife activity in a popular desert nature reserve

Conservation Science and Practice, Volume 8, Issue 8, August 2026.
Abstract Water sources in desert ecosystems are critical for wildlife survival, but they may also attract thousands of visitors, creating potential conflicts between humans and wildlife. Effective management strategies are essential to support human‐wildlife coexistence in these fragile arid environments, allowing for sustainable tourism while ...

A framework for balancing extinction risk between source and recipient populations: Translocation‐based recovery of American martens

Conservation Science and Practice, Volume 8, Issue 8, August 2026.
Translocations are increasingly used for species recovery but are often performed without considering how such actions will impact both recipient and source populations. Herein, we designed an analytical decision‐making framework and applied it to identify suitable translocation programs that promote population viability of both source and recipient ...
