Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Connectivity between breeding sites, wintering areas, and migration routes in Common Terns (Sterna hirundo) breeding in the Western Palaearctic

open access: yesIbis, EarlyView.
Detailed knowledge about bird migration patterns can enhance our understanding of the evolution of migration and temporal changes in space use throughout the annual cycle. Additionally, as many migratory bird species are experiencing population declines, understanding the connectivity between their spatial distributions during breeding, migration and ...

Low breeding propensity in a declining Arctic‐breeding swan revealed by telemetry data

open access: yesIbis, EarlyView.
Many migratory bird populations are declining in the face of habitat degradation and climate change, making it important to identify which stages of their annual cycle are most affected in order to guide conservation measures. The Bewick's Swan Cygnus columbianus bewickii, an Arctic‐breeding waterfowl species, has suffered a dramatic population decline

Geographical distribution of the Pinnated Bittern (Botaurus pinnatus): Update and seasonal movement pattern

open access: yesIbis, EarlyView.
The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...

Wetland Management Strategies that Maximize Marsh Bird Use in the Midwest [PDF]

open access: yes, 2015
We determined marsh bird use across a wide range of wetland types (e.g., emergent, non-vegetated, riparian), hydrologic regimes (e.g., temporary, seasonal, semi-permanent), management practices (e.g., active, passive, unmanaged), and past disturbance ...
