The Allis shad ( Alosa alosa L.) is a threatened anadromous fish species whose populations have dramatically declined in recent decades due to multiple anthropogenic pressures, including habitat fragmentation, water quality degradation and overexploitation. In this study, we aimed (1) to identify the environmental and spatio‐temporal drivers of spawning probability and intensity, and (2) to estimate the number of spawners over...

The effects of environmental seasonality on food web structure have been notoriously understudied in empirical ecology. Here, we focus on seasonal changes in one key attribute of a food web, consumer trophic position. We ask whether fishes inhabiting tropical river–floodplain ecosystems behave as seasonal omnivores, by shifting their trophic positions in relation to the annual flood pulse, or whether they feed at the same trop...

The assessment of climate change impacts on biodiversity has so far been biased toward the taxonomic identification of the species likely either to benefit from climate modifications or to experience overall declines. There have still been few studies intended to correlate the characteristics of species to their sensitivity to climate change, even though it is now recognized that functional trait‐based approaches are promising...
