Migratory behavior and connectivity revealed in a secretive Neotropical migratory songbird, the Swainson’s Warbler

Journal of Field Ornithology, 2022
Improving our understanding of migratory behaviors and connectivity is fundamental for identifying limiting factors and drivers of population decline. With advances in miniaturized tracking technology, we are now able to study these critical aspects of ...

Winter connectivity and leapfrog migration in a migratory passerine

Ecology and Evolution, 2023
Technological advances in migratory tracking tools have revealed a remarkable diversity in migratory patterns. One such pattern is leapfrog migration, where individuals that breed further north migrate to locations further south.

Cross‐continental migratory connectivity and spatiotemporal migratory patterns in the great reed warbler

Journal of Avian Biology, 2016
Migratory connectivity describes to which degree different breeding populations have distinct (non‐overlapping) non‐breeding sites. Uncovering the level of migratory connectivity is crucial for effective conservation actions and for understanding of the ...

Extreme migratory connectivity and apparent mirroring of non-breeding grounds conditions in a severely declining breeding population of an Afro-Palearctic migratory bird [PDF]

Scientific Reports
Understanding the distribution of breeding populations of migratory animals in the non-breeding period (migratory connectivity) is important for understanding their response to environmental change.

Migratory connectivity and population-specific migration routes in a long-distance migratory bird. [PDF]

Proc Biol Sci, 2014
Knowledge about migratory connectivity, the degree to which individuals from the same breeding site migrate to the same wintering site, is essential to understand processes affecting populations of migrants throughout the annual cycle.

Migratory Connectivity at High Latitudes: Sabine's Gulls (Xema sabini) from a Colony in the Canadian High Arctic Migrate to Different Oceans. [PDF]

PLoS ONE, 2016
The world's Arctic latitudes are some of the most recently colonized by birds, and an understanding of the migratory connectivity of circumpolar species offers insights into the mechanisms of range expansion and speciation.

Low migratory connectivity is common in long‐distance migrant birds [PDF]

Journal of Animal Ecology, 2017
Summary Estimating how much long‐distance migrant populations spread out and mix during the non‐breeding season (migratory connectivity) is essential for understanding and predicting population dynamics in the face of global change. We quantify variation in population spread and inter‐population mixing in long‐distance, terrestrial migrant land‐bird

An integrative framework to combine migratory connectivity and demographic data

Methods in Ecology and Evolution
Migratory species experience various conditions and events throughout their annual cycle that influence their spatial and demographic dynamics. To understand these dynamics, it is essential to describe the origin and destination of individuals. Migratory

Effects of Natal Dispersal and Density-Dependence on Connectivity Patterns and Population Dynamics in a Migratory Network

Frontiers in Ecology and Evolution, 2019
Migratory species can be visualized as occupying spatial networks with nodes representing regions and the populations that seasonally occupy them and links between seasonal subpopulations representing migratory connectivity.

Lake sturgeon behavioral diversity in the Laurentian great lakes: migratory patterns across populations and habitats [PDF]

Movement Ecology
Background Characterizing the diversity of migration behaviors from the individual to the population level is essential for understanding how organisms respond to environmental variation and how these responses affect survival and habitat use.
