Interbasin water transfer, riverine connectivity, and spatial controls on fish biodiversity Interbasin water transfer, riverine connectivity, and spatial controls on fish biodiversity
Background Large-scale inter-basin water transfer (IBWT) projects are commonly proposed as solutions to water distribution and supply problems. These problems are likely to intensify under future population growth and climate change scenarios. Scarce data on the distribution of freshwater fishes frequently limits the ability to assess the potential implications of an IBWT project on...

Structural complexity, movement bias, and metapopulation extinction risk in dendritic ecological networks Structural complexity, movement bias, and metapopulation extinction risk in dendritic ecological networks
Spatial complexity in metacommunities can be separated into 3 main components: size (i.e., number of habitat patches), spatial arrangement of habitat patches (network topology), and diversity of habitat patch types. Much attention has been paid to lattice-type networks, such as patch-based metapopulations, but interest in understanding ecological networks of alternative geometries is...

Landscape matrix mediates occupancy dynamics of Neotropical avian insectivores Landscape matrix mediates occupancy dynamics of Neotropical avian insectivores
In addition to patch‐level attributes (i.e., area and isolation), the nature of land cover between habitat patches (the matrix) may drive colonization and extinction dynamics in fragmented landscapes. Despite a long‐standing recognition of matrix effects in fragmented systems, an understanding of the relative impacts of different types of land cover on patterns and dynamics of species...

How restructuring river connectivity changes freshwater fish biodiversity and biogeography How restructuring river connectivity changes freshwater fish biodiversity and biogeography
Interbasin water transfer projects, in which river connectivity is restructured via man-made canals, are an increasingly popular solution to address the spatial mismatch between supply and demand of fresh water. However, the ecological consequences of such restructuring remain largely unexplored, and there are no general theoretical guidelines from which to derive these expectations...

Improving occupancy estimation when two types of observational error occur: Non-detection and species misidentification Improving occupancy estimation when two types of observational error occur: Non-detection and species misidentification
Efforts to draw inferences about species occurrence frequently account for false negatives, the common situation when individuals of a species are not detected even when a site is occupied. However, recent studies suggest the need to also deal with false positives, which occur when species are misidentified so that a species is recorded as detected when a site is unoccupied. Bias in...

Metacommunity theory as a multispecies, multiscale framework for studying the influence of river network structure on riverine communities and ecosystems Metacommunity theory as a multispecies, multiscale framework for studying the influence of river network structure on riverine communities and ecosystems
Explaining the mechanisms underlying patterns of species diversity and composition in riverine networks is challenging. Historically, community ecologists have conceived of communities as largely isolated entities and have focused on local environmental factors and interspecific interactions as the major forces determining species composition. However, stream ecologists have long...
