Metacommunity ecology addresses the situation where sets of local communities are
connected by the dispersal of a number of potentially interacting species. Aquatic systems …

The River Continuum Concept (RCC) is a milestone in stream ecology because of its
comprehensive evaluation of the structure and function of lotic ecosystems. Linking stream …

River networks are hierarchical dendritic habitats embedded within the terrestrial landscape,
with varying connectivity between sites depending on their positions along the network. This …

Recently, community ecologists are focusing on the relative importance of local
environmental factors and proxies to dispersal limitation to explain spatial variation in …

Most bioassessment programs rest on the assumption that species have different niches,
and that abiotic environmental conditions and changes therein determine community …

Understanding changes in water quality over time and landscape and anthropogenic factors
affecting them are of paramount importance to human and ecosystem health. We analyzed …

Within a metacommunity, both environmental and spatial processes regulate variation in
local community structure. The strength of these processes may vary depending on species …

Metacommunity patterns and underlying processes in aquatic organisms have typically
been studied within a drainage basin. We examined variation in the composition of six …

Frequent and severe disruptions of natural river flows associated with human activities
significantly alter hydrological connectivity in large river networks, with deleterious effects on …

Ecologists have long investigated why communities are composed of a few common species
and many rare species. Most studies relate rarity to either niche differentiation among …
