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

Connectivity is classically considered an emergent property of landscapes encapsulating
individuals' flows across space. However, its operational use requires a precise …

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

We address a generalization of the concept of metapopulation capacity for trees and
networks acting as the template for ecological interactions. The original measure had been …

They may influence us as individuals by their encouragement and guidance; they may affect
their community through their untiring commitment to service and the greater good; or they …

The influence of spatial processes on diversity and community dynamics is generally
recognized in ecology and also applied to conservation projects involving forest and …

Increases in river fragmentation globally threaten freshwater biodiversity. Rivers are
fragmented by many agents, both natural and anthropogenic. We review the distribution and …

Hydrochory, or the passive dispersal of organisms by water, is an important means of
propagule transport, especially for plants. During recent years, knowledge about hydrochory …

Increasingly, ecologists conceptualize local communities as connected to a regional species
pool rather than as isolated entities. By this paradigm, community structure is determined …

Despite decades of research on the ecological consequences of stream network expansion,
contraction and fragmentation, surprisingly little is known about the hydrological …
