Over the past centuries, humans have been transforming the biogeophysical landscape that carried species evolution over the geological past. Sharks and their relatives represent one of the lineages struggling to keep pace with the new challenges of the Anthropocene, with over a third of their species under extinction risk. Increasingly aware of the ecological and socioeconomic value of this group, researchers have been strivin...

Despite the long evolutionary history of this group, the challenges brought by the Anthropocene have been inflicting an extensive pressure over sharks and their relatives. Overexploitation has been driving a worldwide decline in elasmobranch populations, and rapid environmental change, triggered by anthropogenic activities, may further test this group's resilience. In this context, we searched the literature for peer-reviewed...

Cleaning symbioses play an important role in the health of certain coastal marine communities. These interspecific associations often occur at specific sites (cleaning stations) where a cleaner organism (commonly a fish or shrimp) removes ectoparasites/damaged tissue from a ‘client’ (a larger cooperating fish). At present, the potential impact of climate change on the fitness of cleaner organisms remains unknown. This study in...
