Dogs are considered humans’ best friend, but this relationship is not all puppies and sunshine. Zoonoses, biting incidents, hereditary problems, and other welfare issues can threaten the relationship, especially when humans are not aware of them. Public opinion on dogs in the densely populated Netherlands …

Verveling zou een veelvoorkomend en ernstig dierenwelzijnsprobleem kunnen zijn (Burn, 2017;Meagher, 2019). Verveling bij honden zou daarbij mogelijk verergerd zijn door de gevolgen van decoronacrisis (Christley et al., 2020). Hondeneigenaren zouden een belangrijke rol kunnen spelen bijhet verlichten …

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, …

Zoonoses, biting incidents, hereditary problems, and other issues can threaten the welfare of both humans and dogs. The Dutch government and animal welfare organizations seem to have little effect in their campaigns to influence the behavior of (potential) dog keepers, who can experience dissonance when …

Elasmobranchen, beter bekend als haaien en roggen, worden algemeen gehouden in aquaria over de hele wereld. Aquariumwelzijn is onder bestudeerd in vergelijking met terrestrische dieren in gevangenschap. Hoewel ze op grote schaal worden gehouden, zijn er maar weinig gepubliceerde studies die het welzijn …

Parasitoids lay their eggs in or on a host, usually another insect. During foraging, parasitoids can encounter insects that differ in terms of host suitability and quality. At one extreme end of this spectrum are non-hosts that are unsuitable for offspring development.Non-hosts are generally ignored …

Communal breeding, wherein multiple conspecifics live and reproduce together, may generate short-term benefits in terms of defence and reproduction. However, its carry-over effects remain unclear. We experimentally tested the effects of communal breeding on parental care and reproduction in burying beetles …

Even in well-studied organisms, it is often challenging to uncover the social and environmental determinants of fitness. Typically, fitness is determined by a variety of factors that act in concert, thus forming complex networks of causal relationships. Moreover, even strong correlations between social …

Animals can alter their foraging behavior through associative learning, where an encounter with an essential resource (e.g., food or a reproductive opportunity) is associated with nearby environmental cues (e.g., volatiles). This can subsequently improve the animal’s foraging efficiency. However, when …
