Starving or Stuffing? Plasticity in Wild Boar Body Mass Variations During Summer in a Mediterranean Area

open access: yesIntegrative Zoology, EarlyView.
Assessing drivers of population dynamics helps to mitigate human–wildlife conflicts. In Mediterranean areas, summer aridity reduces resources, potentially affecting ungulates' body condition and reproduction. In a mixed forested‐rural area, wild boar female body mass increased throughout summer in rainy‐mild years and decreased in hot‐dry years.

Unveiling the Hidden Feast: A Model to Translate Molecular Detection Into Predation Rate—Application Example on Biological Control by Generalist Predators in Agricultural Fields

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT Few processes are as decisive as predation in shaping the structure and dynamics of ecological communities. For most predator species, however, the number of prey items killed by a predator in a day (predation rate) remains impossible to assess because direct observations are scarce or impossible to acquire.
