Global climate change can influence organismic interactions like those between hosts and parasites. Rising temperatures may exacerbate the exploitation of hosts by parasites, especially in ectothermic systems. The metabolic activity of ectotherms is strongly linked to temperature and generally increases when temperatures rise. We hypothesized that temperature change in combination with parasite infection...
Immune systems of vertebrates are much more diverse than previously thought, in particular at the base of the vertebrate clade. RNA-seq was used to describe in detail the transcriptomic response of stickleback hosts to infection by two helminth parasites, the trematode Diplostomum pseudospathaceum (2 genotypes plus a genotype mix) and the cestode Schistocephalus solidus. Based on a global transcription...
Running waters of Central Europe are progressively invaded by the southwest European amphipod Echinogammarus berilloni—as currently observed in the karstic upper River Lippe catchment (Paderborn Plateau, northwest Germany). We tested experimentally whether the succession of the invader is favored by lower predation intensity of three-spined sticklebacks (Gasterosteus aculeatus) compared to predation...
