The population trophic niche of free-living species can be subdivided into smaller niches
comprising individuals specialising on specific food items. The roles of parasites in creating …

Individual foraging specialisation has important ecological implications, but its causes in
group‐living species are unclear. One of the major consequences of group living is …

Abstract The European eel (Anguilla anguilla) is a critically endangered species, whose
recruitment stocks have declined to nearly 1% compared to the late 70s. An amalgam of …

Heterogeneous exposure to parasites may contribute to host species differentiation. Hosts
often harbour multiple parasite species which may interact and thus modify each other's …

Brackish habitats are considered important for the facultatively catadromous European eel,
but knowledge of eel habitat use strategies and the consequences on their condition …

Highlights•Individual foraging specialization in animal groups is largely unconsidered.•We
develop predictions about its causes and consequences in group-living species.•Intragroup …

The network approach is increasingly used by food-web ecologists and ecological
parasitologists and has shed light on how parasite–host assemblages are organized, as …

The introduction of non-native freshwater fish is a primary cause of aquatic biodiversity loss
at global scale. Such introductions have a severe impact on freshwater ecosystems in terms …

Infection patterns of the invasive Anguillicola crassus nematode were investigated in a
population of the European eel Anguilla anguilla where parasite invasion is very recent …

Ontogenetic dietary shifts are common in fish and often impact trophically transmitted
parasite communities. How parasite species composition and relative abundances change …
