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

open access: yesWildlife 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.

Cacao flower visitation: Low pollen deposition, low fruit set and dominance of herbivores

open access: yesEcological Solutions and Evidence, Volume 3, Issue 2, April–June 2022., 2022
Pollination of native cacao is surprisingly understudied, even though the process is crucial for the global chocolate production. In an understudied peruvian region, we found herbivores as dominant flower visitors, and low pollen deposition.Fruit set was low when flowers were pollinated naturally (2%), but also manually (7%). Our findings highlight the

Arboreal monkeys facilitate foraging of terrestrial frugivores

open access: yesBiotropica, Volume 53, Issue 6, Page 1685-1697, November 2021., 2021
We investigated eavesdropping and interspecific interactions in Neotropical mammals in a feeding context using playback experiments, monitoring of fruiting trees with camera traps combined with GPS data and randomised movement tracks. We found that interspecific attractions at food resources were not random and that some species were more likely to ...
