With ongoing environmental change, ultraviolet-B radiation (UVB) reaching the Earth’s surface has increased over recent decades with consequences for terrestrial and also aquatic ecosystems. Despite evidence for direct physiological and immunologic

Animals usually benefit from joining groups, but joining a group can also come at a cost when members expose themselves to competition and the risk of contracting a contagious disease. Therefore, individuals are expected to adjust grouping behaviour

The genetic diversity and population structure of a parasite with a complex life cycle generally depends on the dispersal by its most motile host. Given that high gene flow is assumed to hinder local adaptation, this can impose significant constraint

Mating between relatives often results in inbreeding depression, and is assumed to have a strong effect on fitness traits such as fertility and gonad/gamete quality. However, data concerning this topic are contradictory and particularly scarce in fis

Analysing spatial differences among macroparasite communities is an important tool in the study of host-parasite interactions. Identifying patterns can shed light on the underlying causes of heterogeneity of parasite distribution and help to better u

Mate choice is linked to costs such as time and energy effort or a higher risk of predation. Furthermore, reproduction with a partner of lower than average quality will reduce an individual’s fitness. Copying the mate choice of others is assumed to

Background Mating between close relatives often leads to a reduction of an individual’s fitness, due to an increased expression of deleterious alleles. Thus, in many animal taxa pre- as well as postcopulatory inbreeding avoidance mechanisms have ev

Highlights: • We investigated in vitro responses of stickleback leukocytes to parasite antigens. • In vitro responses decreased from generalist to specialist parasites. • Responses decreased from Gasterosteusaculeatus not infecting to infecting
