Food limitation reduces risk avoidance by prey, but does not increase kill rates in a simple predator–prey system

Ecosphere, 2023
Prey often induce antipredator behaviors when balancing food acquisition against safety. The starvation–predation hypothesis (SPH) posits that, during food shortages, the risk of starvation requires prey to forego antipredator behavior to increase ...

Transboundary Animal Diseases Associated With Cross‐Border Camel Movement. A Systematic Review and Meta‐Analysis

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Transboundary animal diseases (TADs) are contagious diseases that significantly impact livestock health, public health and economic stability. In regions with frequent cross‐border trade and transhumance involving camels, particularly the Middle East and Africa, TADs pose a heightened One Health risk due to their zoonotic potential and capacity to ...

Of all shapes and sizes: a theoretical framework for animal‐mediated terrestrial heterogeneity across scales

Ecography, Volume 2025, Issue 9, September 2025.
Animals redistribute elements throughout their lives by depositing wastes and carcasses. Growing evidence shows that these zoogeochemical processes enhance landscape diversity and heterogeneity worldwide. We provide a descriptive framework for understanding how direct animal depositions (i.e.
