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

Quantifying the strength of migratory connectivity [PDF]
Methods in Ecology and Evolution, 2017 Abstract Technological advancements have spurred rapid growth in the study of migratory connectivity, the linkage of individuals and populations between seasons of the annual cycle. The strength of migratory connectivity is a measure of the co‐occurrence of populations throughout the annual cycle and can be represented by a correlation of the ...

Timing is crucial for consequences of migratory connectivity [PDF]
Oikos, 2015 Migratory connectivity can have important consequences for individuals, populations and communities. We argue that most consequences not only depend on which sites are used but importantly also on when these are used and suggest that the timing of ...

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 ...

Journal of Field Ornithology, 2023 As migratory species move through the stages of their annual cycle, individuals often display variation in the degree to which they remain in proximity to one another, a phenomenon called migratory connectivity.

Migratory pathways and connectivity in Asian houbara bustards: evidence from 15 years of satellite tracking. [PDF]
PLoS ONE, 2011 Information on migratory pathways and connectivity is essential to understanding population dynamics and structure of migrant species. Our manuscript uses a unique dataset, the fruit of 103 individual Asian houbara bustards captured on their breeding ...

Advances in linking wintering migrant birds to their breeding-ground origins using combined analyses of genetic and stable isotope markers. [PDF]
PLoS ONE, 2012 An enduring problem in avian ecology and conservation is linking breeding and wintering grounds of migratory species. As migratory species and populations vary in the degree to which individuals from distinct breeding locales mix on stop-over sites and ...

An evaluation of migration fidelity of Ruby-throated Hummingbirds inferred from stable isotope methods [PDF]
PeerJKnowledge of spatial connectivity between breeding and non-breeding locations of migratory birds and their breeding site fidelity are important for avian conservation.

Ecology and Evolution, 2022 Many populations of long‐distance migrant shorebirds are declining rapidly. Since the 1970s, the lesser yellowlegs (Tringa flavipes) has experienced a pronounced reduction in abundance of ~63%. The potential causes of the species' decline are complex and
