Few studies have evaluated phenotypic plasticity at the community level, considering, for example, plastic responses in an entire species assemblage. In addition, none of these studies have addressed the relationship between phenotypic plasticity and community structure. Within this context, here we assessed the magnitude of seasonal changes in digestive traits (seasonal flexibility), and of ch...

The introduction of non-native fish into the Teuchitlán River, in west-central Mexico, was suggested as a key factor behind change assemblage, and even extinction endemic species. characterization assemblage relationship between abundance anthropogenic conditions were evaluatedover 2-year period. Fish structure, species replacement, dominance examined along longitudinal environmental gradient. ...

The rock-restricted cichlid fish assemblages of Lake Malawi exhibit high spatial diversity in their species composition and relative abundance. However the extent to which this is due to the effects of local environmental differences, dispersal limitation of constituent taxa, and the assignment of allopatric populations to species is uncertain. We examined the factors associated with diversity ...

Snow-fed river Pinder -a tributary of river Alaknanda in central Himalaya was explored for fish assemblages and habitat specificity. Altogether 27 fish species were reported from three orders, four families and nine genera. Cypriniformes order was dominating followed by Siluriformes and Salmoniformes. Shannon-Weiner diversity index (3.09 to 4.10) and Simpson index of diversity (0.81 to 0.92) of...

15 The influence of sea-cage aquaculture on wildfish assemblages has received little attention 16 outside of Europe. Sea-cage aquaculture of finfish is a major focus in South Australia, and 17 while the main species farmed is southern bluefin tuna (Thunnus maccoyii), there is also an 18 important yellowtail kingfish (Seriola lalandi) industry. Yellowtail kingfish aquaculture did 19 not appear t...
