Warming increases trophic cascade strength in an aquatic food chain

Journal of Animal Ecology, EarlyView.
Using experiments and Bayesian dynamical modelling, we demonstrate that warming strengthens trophic cascades in an aquatic food chain through coordinated, temperature‐dependent shifts in predator, prey and resource traits. By tracing indirect effects to underlying mechanisms, our study shows how climate change can amplify predator impacts and ...

Assessment of large‐scale spatial variation in age‐specific survival and age at first breeding in a long‐lived species

Journal of Animal Ecology, EarlyView.
Using nationwide data from over 92,000 individuals, we reveal large‐scale spatio‐temporal variation in age‐dependent survival and age at first breeding in a long‐lived species. By comparing alternative spatial models, we show that demographic variation follows a biologically meaningful spatial structure, with implications for population dynamics ...

Hotter, faster, sicker? Warming shifts the cost of infection from individuals to populations

Journal of Animal Ecology, EarlyView.
This study examines how temperature alters disease impacts across biological scales in a host–pathogen system. We found infected hosts appear healthiest at warm temperatures, yet populations suffer most. This suggests climate warming may intensify disease impacts for populations in ways traditional individual‐level virulence metrics fail to predict ...

From individuals to networks: The role of variation in plant–pollinator communities' responses to global change

Journal of Animal Ecology, EarlyView.
This paper argues that variation among individuals—not just species differences—can shape the sensitivity, robustness and resilience of plant–pollinator communities under global change. By linking individual traits and interaction structure to network dynamics, it provides a new framework and future research directions for predicting community ...

Effect of Salinity Stress on Gut–Brain–Gonad Axis in the Red‐Eared Slider (Trachemys scripta elegans)

Integrative Zoology, EarlyView.
The increase in salinity leads to changes in the gut microbiota and metabolites of Trachemys scripta elegans, affecting the synthesis and secretion of neurotransmitters or precursors, which can inhibit the secretion of reproductive hormones and affect the self‐renewal and differentiation process of spermatogonial stem cells.
