Proximate Drivers of Migration and Dispersal in Wing-Monomorphic Insects
Insects, 2020 Gains in our knowledge of dispersal and migration in insects have been largely limited to either wing-dimorphic species or current genetic model systems.

Avian Conservation and Ecology, 2023 Understanding the threats faced by a bird species requires a knowledge of their movements throughout the annual cycle and, for migratory species, the degree of connectivity between breeding and wintering sites.

Age-Dependent Dispersal and Relatedness in Tiger Sharks (Galeocerdo cuvier)
Frontiers in Marine Science, 2022 Understanding dispersal in large marine fauna is necessary for conservation, but movement patterns often vary widely by sex and life stage. In sharks, genetic studies have shown evidence of widespread male-biased dispersal, though tagging and tracking ...

Winter Philopatry in Migratory Waterfowl [PDF]
The Auk, 1999 Philopatry in migratory species can apply to any location used during the annual cycle. The degree of philopatry influences the genetic structure of populations, but only at the stage of the annual cycle when pair formation and gene exchange occur. Because pair formation in birds typically occurs during the breeding season, most studies have fo- cused ...

Evolutionary Applications, 2021 Understanding species responses to past environmental changes can help forecast how they will cope with ongoing climate changes. Harbor porpoises are widely distributed in the North Atlantic and were deeply impacted by the Pleistocene changes with the ...

The Cognitive Ecology of Animal Movement: Evidence From Birds and Mammals
Frontiers in Ecology and Evolution, 2021 Cognition, defined as the processes concerned with the acquisition, retention and use of information, underlies animals’ abilities to navigate their local surroundings, embark on long-distance seasonal migrations, and socially learn information relevant ...

Study design and mark-recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale [PDF]
, 2012 Accurate data on dispersal ability are vital to the understanding of how species are affected by fragmented landscapes. However, three factors may limit the ability of field studies to detect a representative sample of dispersal events: (1) the number of

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 ...

Dispersal costs set the scene for helping in an atypical avian cooperative breeder [PDF]
, 2001 The ecological constraints hypothesis is suggested to explain the evolution of cooperative breeding in birds. This hypothesis predicts that the scene for cooperative breeding is set when ecological factors constrain offspring from dispersal.
