Since the return of the grey wolf (Canis lupus) in the Netherlands in 2015, much research has been done on the ecology and distribution of the species. This has led to a dietary study using hair- and DNA-sampling of wolf scats, and preliminary analyses of DNA in wolf scats showed that DNA from non-prey, …

Residing atop the trophic ladder, the jaguar plays a crucial role in the functioning, stability, and resilience of neotropical forest ecosystems. They influence the entire food web and have wide-ranging effects on various ecological processes. However, jaguars are a highly at-risk and near-threatened …

Implementation of reliable methodologies allowing Reduction, Refinement, and Replacement (3Rs) of animal testing is a process that takes several decades and is still not complete. Reliable methods are essential for regulatory hazard assessment of chemicals where differences in test protocol can influence …

Global climate change is resulting in a wide range of biotic responses, including changes in diel activity and seasonal phenology patterns, range shifts polewards in each hemisphere and/or to higher elevations, and altered intensity and frequency of interactions between species in ecosystems.Oak (Thaumetopoea …

Global climate change (CC) affects marine mammals, such as cetaceans, by exposing them to an altered marine environment. Cetaceans are indirectly influenced by CC (e.g. through their prey, warmer environment). They are indicator species, significant to marine ecosystems and one of the most endangered …
