A general theory of avian migratory connectivity [PDF]

Ecology Letters, 2021
Abstract Birds exhibit a remarkable array of seasonal migrations. Despite much research describing migratory behaviour, the underlying forces driving how a species’ breeding and wintering populations redistribute each year, that is, migratory connectivity, remain largely unknown.

Dynamics of fish larvae recruitment in the hydrographic basin of the Paraguay River in western Brazil [PDF]

Neotropical Ichthyology, 2023
The conservation of fish assemblages depends on the longitudinal and lateral connectivity between riverine habitats, in particular during the breeding season and the initial development.

Clustering community science data to infer songbird migratory connectivity in the Western Hemisphere

Ecosphere, 2022
Migratory connectivity describes the spatial linkage among migrating individuals through time. Accounting for it is necessary for full annual cycle conservation planning, to avoid uneven protection leading to overall population declines.

Optimal conservation of migratory species. [PDF]

PLoS ONE, 2007
BACKGROUND: Migratory animals comprise a significant portion of biodiversity worldwide with annual investment for their conservation exceeding several billion dollars. Designing effective conservation plans presents enormous challenges. Migratory species

Eco‐evolutionary drivers of avian migratory connectivity

Ecology Letters, 2022
Abstract Migratory connectivity, reflecting the extent by which migrants tend to maintain their reciprocal positions in seasonal ranges, can assist in the conservation and management of mobile species, yet relevant drivers remain unclear.

Stable isotope analysis provides new information on winter habitat use of declining avian migrants that is relevant to their conservation [PDF]

, 2012
Winter habitat use and the magnitude of migratory connectivity are important parameters when assessing drivers of the marked declines in avian migrants. Such information is unavailable for most species.

Differential population trends align with migratory connectivity in an endangered shorebird

Conservation Science and Practice, 2022
Migratory connectivity describes the extent to which migratory species' populations are connected throughout the annual cycle. While recognized as critical for understanding the population dynamics of migratory species and conserving them, empirical ...

A quantitative measure of migratory connectivity [PDF]

Journal of Theoretical Biology, 2009
The study of the extent of the connection between areas where populations of birds breed and areas where they winter has flourished in recent years mainly thanks to the development of new techniques, but also due to traditional ringing and recovery schemes, which allow tracking of individuals or populations linking wintering and breeding distributions.

Spatial structure in migration routes maintained despite regional convergence among eastern populations of Swainson’s Thrushes

Movement Ecology, 2021
Background Migratory connectivity links the different populations across the full cycle and across the species range and may lead to differences in survival among populations.

Migratory insights from singing humpback whales recorded around central New Zealand [PDF]

Royal Society Open Science, 2020
The migration routes of wide-ranging species can be difficult to study, particularly at sea. In the western South Pacific, migratory routes of humpback whales between breeding and feeding areas are unclear. Male humpback whales sing a population-specific
