Convergence of fish communities from the littoral zone of reservoirs
1. Understanding factors that regulate the assembly of communities is a main focus of ecology. Human-engineered habitats, such as reservoirs, may provide insight into these assembly processes because they represent novel habitats that are subjected to colonization by fishes from the surrounding river basin or transported by humans. By contrasting community similarity within and among reservoirs...
متن کاملLittoral zone structures as Daphnia refugia against fish predators
The assumption that macrophytes can provide zooplankton a daytime refuge against fish predation is central to the diel horizontal migration hypothesis. However, previous observations and experiments have shown that largebodied zooplankton avoid macrophytes. To directly test these contrasting roles of macrophytes, we measured the reaction of Daphnia pulex to macrophytes (Elodea canadensis or pla...

Seasonal changein the abundance. biornass and species richness of fixh in the littoral zone of Lake Coustancc were examined. Electric fishing was conducted in three depth strata at six different sampling sitc« within the littoral zone from Novem ber ]991 to Fcbruar ]993 during daytime. Minimal abundance and biomaxs values were observed in February with 3.9 (SO ± ..\..2) ind· lOO Ill-" and 12.7...
متن کاملPhycoerythrin Signatures in the Littoral Zone
I am interested in understanding how, and in what ways, the taxonomic composition of the phytoplankton affects ecosystem-level processes in the sea. I am particularly interested in the relationship between the optical environment and the distribution of phytoplankton with different light harvesting pigments. To this end, I have been working in collaboration with experts in remote sensing and oc...
