Mediterranean octocoral populations exposed to marine heatwaves are less resilient to disturbances. [PDF]

J Anim Ecol
We demonstrate that marine heat waves decrease the resilience of Mediterranean octocorals to further disturbances. Abstract The effects of climate change are now more pervasive than ever. Marine ecosystems have been particularly impacted by climate change, with marine heatwaves (MHWs) being a strong driver of mass mortality events.

Functional traits of young seedlings predict trade‐offs in seedling performance in three neotropical forests

Journal of Ecology, Volume 111, Issue 12, Page 2568-2582, December 2023., 2023
With strikingly consistent patterns across three tropical forests, the authors find strong evidence for the promise of functional traits to provide mechanistic links between seedling form and demographic performance. Abstract Understanding the mechanisms that promote the coexistence of hundreds of species over small areas in tropical forest remains a ...

Predator‐induced defences under tropicalisation: A biogeographic approach

Journal of Biogeography, Volume 50, Issue 12, Page 2148-2159, December 2023., 2023
Abstract Aim The biogeography of predator‐induced defences is an understudied area of predator–prey dynamics. Range overlap with predators that induce the response and local demographics (e.g., prey abundances) are likely to be important factors for determining the biogeographic distribution of induced defences within species.

Berries and bullets: influence of food and mortality risk on grizzly bears in British Columbia Bayas y balas: influencia de la alimentación y el riesgo de mortalidad en los osos grizzly en la Columbia Británica Des baies et des balles: influence de l'alimentation et risques de mortalité chez les ours grizzlys de la Colombie‐Britannique

Wildlife Monographs, Volume 213, Issue 1, November 2023., 2023
We developed a spatialized surface for the primary food of grizzly bears in southeast British Columbia. After using this huckleberry patch layer to model habitat selection, fitness, and density, in a bottom‐up top‐down paradigm, we found that huckleberry patches near forestry roads contribute very little to fitness and density.
