Amphibians form a major component of the diet of the otter Lutra lutra in several areas of its
wide geographic range. Yet, amphibian remains are rarely identified to species level and …

Maintaining thermal homeostasis in water is a major challenge for semi‐aquatic mammals,
which entails morphological, behavioural and physiological adaptations. Foraging strategies …

Temporary streams and rivers, also referred to as intermittent, are defined as waterways that
cease to flow at some points in space and time along their course. They are shaped by …

Carnivores are threatened worldwide through habitat loss and persecution. Habitat
destruction is a major threat for the Eurasian otter. Its populations declined drastically in …

Abstract The Eurasian otter Lutra lutra is a territorial semi-aquatic carnivore usually found at
low densities in rivers, coastal areas, and wetlands. Its diet is based on prey associated with …

The conservation of submerged vegetation is crucial in the functioning of aquatic
ecosystems. We have assessed, by means of subaquatic quantitative sampling transects …

The invasive red swamp crayfish (Procambarus clarkii) has become a major food resource
for Eurasian otters (Lutra lutra) in the Iberian Peninsula. Crayfish accumulate large amounts …

River damming promotes profound changes in aquatic biodiversity, including the facilitation
of biological invasions, with subsequent impacts on native communities. The Eurasian otter …

In anthropogenic landscapes, which are usually characterized by the existence of highly
heterogeneous patchworks of habitats with different conservation status, restored gravel pits …

Positive interactions between birds and mammals are a fascinating aspect of animal
behaviour. Feeding associations may consist of local enhancement or facilitation, and in the …
