Humans have contributed to the increased frequency and severity of emerging infectious
diseases, which pose a significant threat to wild and domestic species, as well as human …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Most hosts and parasites exist in diverse communities wherein they interact with other
species, spanning the parasite–mutualist continuum. These additional interactions have the …

Evolutionary biologists have long trained their sights on adaptation, focusing on the power of
natural selection to produce relative fitness advantages while often ignoring changes in …

Host resistance to parasites is a rapidly evolving trait that can influence how hosts modify
ecosystems. Eco-evolutionary feedbacks may develop if the ecosystem effects of host …

In our rapidly changing world, understanding how species respond to shifting conditions is
of paramount importance. Pharmaceutical pollutants are widespread in aquatic ecosystems …

Epigenetic modification, especially DNA methylation, can play an important role in mediating
gene regulatory response to environmental stressors and may be a key process affecting …

Background Parasite switches to new host species are of fundamental scientific interest and
may be considered an important speciation mechanism. For numerous monogenean fish …

Sexually selected ornaments range from highly dynamic traits to those that are fixed during
development and relatively static throughout sexual maturity. Ornaments along this …

General laws in ecological parasitology are scarce. Here, we evaluate data on numbers of
fish parasites published by over 200 authors to determine whether acquiring parasites via …
