Migratory connectivity of North American waterfowl across administrative flyways
Ecological Applications, 2023AbstractManagement of waterfowl that migrate seasonally across North America occurs within four flyways that were delineated in the early 1900s to include the annual movements of populations. Movements may have changed over the past century since the administrative flyways were established, and may do so while management plans are in use, so ...

Assessing migratory connectivity for a long‐distance migratory bird using multiple intrinsic markers
Ecological Applications, 2014Patterns of migratory connectivity are a vital yet poorly understood component of the ecology and evolution of migratory birds. Our ability to accurately characterize patterns of migratory connectivity is often limited by the spatial resolution of the data, but recent advances in probabilistic assignment approaches have begun pairing stable isotopes ...

Understanding migratory connectivity is critical for interpreting population dynamics, seasonal interactions, and for the implementation of conservation strategies of migratory species. We evaluated the migratory connectivity of a Neotropical migratory songbird, the Ovenbird (Seiurus aurocapilla) using archival light‐level geolocators deployed at two ...

Unravelling migratory connections: the next level
Molecular Ecology, 2013Migration is widespread among birds, and the strength of the link between the breeding and wintering grounds, migratory connectivity, influences many ecological and evolutionary processes. Despite its importance, migratory connectivity is poorly estimated for most species.

THE PAST AND PRESENT OF MIGRATORY CONNECTIVITY
Ornithological Monographs, 2006degree to which two or more periods of the annual cycle are geographically linked. The term was first proposed by a group of scientists during a workshop on "Connectivity of Migratory Birds" in October 2000 sponsored by the National Science Foundation (Webster et al. 2002, Rubenstein and Hobson 2004).

Migratory connectivity in barn swallows and other hirundines
Journal of Ornithology, 2007Environmental indicators such as the Normalized Difference Vegetation Index (NDVI) (Pettorelli et al. 2005) provide important insights into spatial and temporal patterns of primary productivity and hence food availability for many different organisms, including barn swallows Hirundo rustica (Saino et al. 2004a, b).

Making Migratory Connections with Stable Isotopes
2003A fundamental aim of marking and tracking migratory birds is to link breeding, wintering and stopover areas within discrete populations. Such information allows critical insight into factors influencing populations at several geographical scales and so is fundamental to conservation of migrant birds (Myers et al. 1987; Moore et al.

Arctic geese, migratory connectivity and agricultural change
Ardea -Wageningen-, 2006The current favourable numerical status of most arctic-breeding goose populations conceals an increasing dependence on man-modified habitats for much of the year. Almost all populations are now heavily dependent on agricultural crops when the birds are away from the arctic breeding grounds.
