Quantifying the strength of migratory connectivity [PDF]

open access: yesMethods 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 ...

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

open access: yes, 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.

Fine-scale population structure and asymmetrical dispersal in an obligate salt-marsh passerine, the Saltmarsh Sparrow (Ammodramus Caudacutus) [PDF]

open access: yes, 2012
Understanding the spatial scale of gene flow can yield valuable insight into the ecology of an organism and guide conservation strategies. Fine-scale genetic structure is uncommon in migratory passerines because of their high vagility and presumed high ...

Migration ecology of western gray catbirds

open access: yesMovement 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 ...

Usage of Specialized Fence-Gaps in a Black Rhinoceros Conservancy in Kenya [PDF]

open access: yes, 2016
Fencing is increasingly used in wildlife conservation. Keeping wildlife segregated from local communities, while permitting wildlife access to the greater landscape matrix is a complex task.

The strength of migratory connectivity in Painted Buntings is spatial scale dependent and shaped by molting behavior

open access: yesJournal 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]

open access: yesPLoS 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]

open access: yesPLoS 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]

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