Over the last five years, I have found myself circling around four key concepts: Performance. Philosophy. Animals. And Equality. And I have found myself thinking in and with circles. It began with the various references to circles we can find in the philosophy of Henri Bergson - in his idea of the field …

Plastic pollution of rivers, seas, and oceans is currently one of the most pressing environmental issues. The litter traps constructed by CLEAR RIVERS provide a way to clean the rivers of litter by utilising winds and currents. CLEAR RIVERS wants to know how to improve the effectiveness of current litter …

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, …

Predation risk is a major driver of the distribution of prey animals, which typically show strong responses to cues for predator presence. An unresolved question is whether naïve individuals respond to mimicked cues, and whether such cues can be used to deter prey. We investigated whether playback of …

Camera trap technology has galvanized the study of predator-prey ecology in wild animal communities by expanding the scale and diversity of predator-prey interactions that can be analyzed. While observational data from systematic camera arrays have informed inferences on the spatiotemporal outcomes of …

Studying animal grouping behavior is important for understanding the causes and consequences of sociality and has implications for conservation. Chimpanzee (Pan troglodytes) party size is often assessed by counting individuals or extracted indirectly from camera trap footage or the number of nests. Little …

The invasive lionfish (Pterois volitans and Pterois miles) started invading the Caribbean Sea since the 1980’s and were first sighted on the Saba Bank since 2009 where they established themselves fully during the following two years. They have no specific preference for prey species and their predation …

Insect hyperparasitoids are fourth trophic level organisms that commonly occur in terrestrial food webs, yet they are relatively understudied. These top-carnivores can disrupt biological pest control by suppressing the populations of their parasitoid hosts, leading to pest outbreaks, especially in confined …

Spatial variation in habitat riskiness has a major influence on the predator–prey space race. However, the outcome of this race can be modulated if prey shares enemies with fellow prey (i.e., another prey species). Sharing of natural enemies may result in apparent competition, and its implications for …

This is the report of a research that was conducted on the mammal distribution in CNCH. The research was conducted with the following research question: is there a difference in distribution of endangered and vulnerable mammal species between the slightly disturbed primary forests and the highly disturbed …
