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.

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 ...

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.

An evaluation of migration fidelity of Ruby-throated Hummingbirds inferred from stable isotope methods [PDF]

PeerJ
Knowledge of spatial connectivity between breeding and non-breeding locations of migratory birds and their breeding site fidelity are important for avian conservation.

Migratory connectivity and variation in migration phenology within the Pacific population of Barrow's Goldeneye (Bucephala islandica)

Avian Conservation and Ecology, 2022
Effective management of migratory animals requires an understanding of individual movement patterns throughout the annual cycle. We used satellite transmitters to track adult Barrow’s Goldeneye (Bucephala islandica) captured at five wintering sites, one ...

Habitat distribution affects connectivity and population size in migratory networks [PDF]

Theoretical Ecology, 2022
Abstract Population dynamics of migratory species can be modeled using spatial bipartite networks in which breeding and winter regions, or nodes, are distributed longitudinally and connected by links representing migratory movements. Understanding the factors that influence the connectivity and population size of such networks is important for ...

Multi-isotope (δ²H, δ¹³C, δ¹⁵N) feather profiles and morphometrics inform patterns of migratory connectivity in three species of North American swallows. [PDF]

Mov Ecol, 2023
Aerial insectivorous birds have suffered steep population declines in North America over the last 60 years. A lack of information on migratory connectivity between breeding and non-breeding grounds for these species limits our ability to interpret ...

Migration strategies, connectivity and corridor features of the partial migrant little bustard (Tetrax tetrax) across the Iberian Peninsula [PDF]

Movement Ecology
The study of migration ecology is crucial for understanding the factors and pressures affecting migratory species. Here, we studied the migratory ecology of the little bustard (Tetrax tetrax), a steppe bird that has suffered a sharp decline over recent ...

Estimating migratory connectivity of birds when re-encounter probabilities are heterogeneous. [PDF]

Ecol Evol, 2014
AbstractUnderstanding the biology and conducting effective conservation of migratory species requires an understanding of migratory connectivity – the geographic linkages of populations between stages of the annual cycle. Unfortunately, for most species, we are lacking such information.

Migratory connectivity then and now: a northward shift in breeding origins of a long-distance migratory bird wintering in the tropics. [PDF]

Proc Biol Sci, 2021
Temporal variation in the connectivity of populations of migratory animals has not been widely documented, despite having important repercussions for population ecology and conservation.
