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

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 ...

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

, 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 ...

Combining Tracking and Remote Sensing to Identify Critical Year-Round Site, Habitat Use and Migratory Connectivity of a Threatened Waterbird Species

Remote Sensing, 2021
We tracked 39 western flyway white-naped cranes (Antigone vipio) throughout multiple annual cycles from June 2017 to July 2020, using GSM-GPS loggers providing positions every 10-min to describe migration routes and key staging areas used between their ...

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 ...

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

, 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.

Insights into migratory connectivity and conservation concerns of Red Knots Calidris canutus in the austral Pacific coast of the Americas

Bird conservation international, 2021
Summary Migratory species rely on several distant sites during the annual cycle which makes their conservation more complex than that of non-migratory species. Even one of the most extensively studied migratory shorebirds - the Red Knot Calidris canutus -

Flyway‐scale GPS tracking reveals migratory routes and key stopover and non‐breeding locations of lesser yellowlegs

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

Developing fencing policies in dryland ecosystems [PDF]

, 2015
The daily energy requirements of animals are determined by a combination of physical and physiological factors, but food availability may challenge the capacity to meet nutritional needs.

Provenance does matter: links between winter trophic segregation and the migratory origins of European robins [PDF]

, 2016
Amongst migratory species, it is common to find individuals from different populations or geographical origins sharing staging or wintering areas.
