Crossing large bodies of water can be extremely risky for terrestrial migrants and yet such migrants have been observed to cross hundreds and even thousands of kilometres of water. However, the mechanisms that enable nocturnal migrants to cross large bodies of water successfully remain unclear. In the north of the Netherlands, autumn migration of b...

Highlights ► We test for changes in sexual selection following an experimental introduction in guppies. ► Introduced populations do not differ in male mating signals or female preferences. ► Female preferences vary between rivers but not predation environments. ► Female preferences do not predictably respond to divergent natural selection.

Highlights ► In a wide variety of taxa, males are equipped with harmful genital structures. ► One suggested function for genital spines has been that they function as an anchor. ► We used five populations of seed beetles to test this hypothesis. ► We show that longer genital spines do not function as better anchors during mating. ► We also show tha...

Highlights ► We examined whether female prairie voles prefer males with long avpr1a microsatellite alleles. ► Females showed social and sexual preferences for males with long avpr1a microsatellite alleles. ► Females from two natural populations behaved similarly. ► Prior laboratory studies showed that males with longer avpr1a microsatellite alleles...

In social species with fission–fusion dynamics, individuals have the opportunity to recruit other individuals selectively by calling. An individual’s decision to call to another could be determined by previous interactions with that individual, which would require individuals to be able to discriminate others based on their vocalizations and associ...

Lateralization in dogs, Canis familiaris, has been reported for paw usage and response to visual and acoustic stimuli. Surprisingly, however, no investigation of possible lateralization for the most relevant sensory domain of dogs, namely olfaction, has been carried out. Here we investigated left and right nostril use in dogs freely sniffing differ...

Highlights► The giant water bug Abedus herberti exhibits two respiratory behaviours. ► These behaviours increase the time that the bugs may remain submerged in water. ► Expression is greatest in deep water and less common in shallow water. ► These behaviours most likely increase fitness and decrease energy use.

Highlights ► Cephalic secretions occur in male Oedothorax retusus spiders. ► Experimentally covered males are compared to noncovered males. ► We investigate effects of secretions on mating, oviposition and paternity. ► Secretions function as precopulatory mating effort and stimulate female fecundity. ► Females do not selectively use sperm of males ...
