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.

When and where to count? Implications of migratory connectivity and non-breeding distribution to population censuses in a migratory bird population

bioRxiv, 2022
Migratory connectivity is a metric of the co-occurrence of migratory animals originating from different breeding sites, and like their spatio-temporal distributions, can vary substantially during the annual cycle.

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

Integrating tracking and resight data enables unbiased inferences about migratory connectivity and winter range survival from archival tags

Ornithological Applications, 2021
Archival geolocators have transformed the study of small, migratory organisms but analysis of data from these devices requires bias correction because tags are only recovered from individuals that survive and are re-captured at their tagging location. We

A multi-method approach to delineate and validate migratory corridors [PDF]

, 2017
Context: Managers are faced with numerous methods for delineating wildlife movement corridors, and often must make decisions with limited data. Delineated corridors should be robust to different data and models.

Migratory connectivity and timing for an at-risk Canadian landbird, Eastern Whip-poor-will (Antrostomus vociferus), from two geographically distant breeding areas

Canadian Journal of Zoology, 2022
Determining the year-round spatial distributions of at-risk avian migratory species is critical for effective conservation. High-precision tracking enables the identification of distant breeding and nonbreeding areas and their connectivity, as well as ...

Annual movements of a migratory seabird—the NW European red-throated diver (Gavia stellata)—reveals high individual repeatability but low migratory connectivity

Marine Biology, 2022
In this study, the annual movements of a seabird species, the red-throated diver (Gavia stellata), were investigated in space and time. Between 2015 and 2017, 33 individuals were fitted with satellite transmitters at the German Bight (eastern North Sea).

Migration ecology of western gray catbirds

Movement Ecology, 2021
Background For many songbirds in North America, we lack movement details about the full annual cycle, notably outside the breeding season. Understanding how populations are linked spatially between breeding and overwintering periods (migratory ...
