Per-and polyfluoroalkyl substances (PFAS) are a group of emerging substances that have
proved to be persistent and highly bioaccumulative. They are broadly used in various …

We evaluated the biogeographic factors that influence composition and diversity of the
Neotropical otter diet. We also tested whether Lontra longicaudis selected fish in its diet per …

Long‐lived top predators shape biodiversity structure in their ecosystems and predator–prey
interactions are critical in decoding how communities function. Studies on the foraging …

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 …

Variation in predator diet is a critical aspect of food web stability, health, and population
dynamics of predator/prey communities. Quantifying diet, particularly among cryptic species …

Several alien predator species have spread widely in Europe during the last five decades
and pose a potential enhanced risk to native nesting ducks and their eggs. Because …

The Eurasian otter Lutra lutra is a generalist carnivore that is widely distributed in many
aquatic ecosystems. Based on its inherent attributes of opportunistic foraging behaviour and …

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

Lack of data on population sizes and resource requirements are major impediments to the
effective conservation of rare species globally. The conservation of the Eurasian otter (Lutra …

Assessing habitat selection is essential to protecting threatened species but also to
understand what factors influence species that, although globally not currently in decline, act …
