Sensitivity of migratory connectivity estimates to spatial sampling design [PDF]

Movement Ecology, 2021
Background The use of statistical methods to quantify the strength of migratory connectivity is commonplace. However, little attention has been given to their sensitivity to spatial sampling designs and scales of inference.

The ‘migratory connectivity’ concept, and its applicability to insect migrants [PDF]

Movement Ecology, 2020
Migratory connectivity describes the degree of linkage between different parts of an animal’s migratory range due to the movement trajectories of individuals.

A synthesis of recent tools and perspectives in migratory connectivity studies [PDF]

Movement Ecology, 2023
Migration movements connect breeding and non-breeding bird populations over the year. Such links, referred to as migratory connectivity, have important implications for migratory population dynamics as they dictate the consequences of localised events ...

Low migratory connectivity and similar migratory strategies in a shorebird with contrasting wintering population trends in Europe and West Africa [PDF]

Scientific Reports
Migratory shorebird populations are declining worldwide, showing an apparent inability to respond to the interplaying challenges emerging along their flyways.

The importance of migratory connectivity for global ocean policy. [PDF]

Proc Biol Sci, 2019
The distributions of migratory species in the ocean span local, national and international jurisdictions. Across these ecologically interconnected regions, migratory marine species interact with anthropogenic stressors throughout their lives. Migratory connectivity, the geographical linking of individuals and populations throughout their migratory ...

Integrating stable isotopes, parasite, and ring‐reencounter data to quantify migratory connectivity—A case study with Barn Swallows breeding in Switzerland, Germany, Sweden, and Finland [PDF]

Ecology and Evolution, 2020
Ecosystems around the world are connected by seasonal migration. The migrant animals themselves are influenced by migratory connectivity through effects on the individual and the population level. Measuring migratory connectivity is notoriously difficult

Migratory connectivity in the context of differential migration. [PDF]

Biol Lett, 2018
Understanding how breeding populations are spatially and temporarily associated with one another over the annual cycle has important implications for population dynamics. Migratory connectivity typically assumes that populations mix randomly; yet, in many species and populations, sex-, age- or other subgroups migrate separately, and/or spend the non ...

Migratory connectivity in the Loggerhead Shrike (Lanius ludovicianus). [PDF]

Ecol Evol, 2018
AbstractAimWe combine genetic and stable isotope data to quantify migration patterns in Loggerhead Shrike (Lanius ludovicianus), a species of conservation concern in North America, to assess how connectivity differs and impacts population evolution, ecology, and conservation.LocationWe sampled shrikes across the majority of their nonbreeding range ...

Wetland suitability and connectivity for trans-Saharan migratory waterbirds. [PDF]

PLoS ONE, 2015
To complete their life cycle waterbirds rely on patchily distributed and often ephemeral wetlands along their migration route in a vast unsuitable matrix.

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.
