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 …

The coral reefs around the world have been under very big pressure. In some places up to 95% coral coverage is already gone. For this big decrease there are many different causes, ranging from natural disasters to predation and sickness. Even humans have a big influence on the coral reefs. To protect …

During times of high activity by predators and competitors, herbivores may be forced to forage in patches of low‐quality food. However, the relative importance in determining where and what herbivores forage still remains unclear, especially for small‐ and intermediate‐sized herbivores. Our objective …

One of the most remarkable phenomena in nature is mimicry, in which one species (the mimic) evolves to imitate the phenotype of another species (the model). Several reasons for the origin of mimicry have been proposed, but no definitive conclusion has been found yet. In this paper, we test several of …

This investigation tries to give more insight in the relation between the Carcinus maenas, acting as predator in this part of the food chain and the Ruditapes philippinarum, being hunted by the Carcinus maenas. The focus in this investigation has been based on the occurrence of the different sizes of …

Due to their high adaptability and opportunistic predation behaviour feral cats have a great impact on worldwide bird biodiversity in particular on islands. However not much is known about their actual behaviour and time budget, as direct behavioural observations often are difficult regarding free-ranging …

Conflicts between livestock owners and wolves are already present for ages in Europe. In southern Europe, especially in areas with important livestock production, wolves may depend heavily on livestock as prey (Iliopoulos et al., 2009). Predation on livestock is the crucial factor promoting wolf persecution. …

This research focuses on the impact of predation (and predation pressure) on brown hares (adult and young) in a multipredator environment, in relation to the seasonal energy requirement of hares. It will thus give an insight in the crucial periods for the brown hare within a year and it will broaden …

Blue mussels (Mytilus edulis) create niches in the Wadden Sea and therefore they are important for the Wadden Sea. Because there are less mussel beds in the Wadden Sea than would be expected and because of their important role, they are monitored since the mid-nineties. It was found that some beds were …

Ghanaian farmers suffer from a decline in cocoa production partly due to damages and diseases from insect pests. To increase predation by bats on insects on the cocoa plantations we installed two different types of bat boxes on 15 plantations around the village of Buoyem. Bat activity, bat species composition …
