Migratory Behavior and Survival of Adult Female Elk in a Partially Migratory Population
… greater degree than non-migratory conspecifics. Partial migration occurs when a portion of the population migrates and the other portion remains on the shared range, and is expected to be maintained by balancing fitness between migrant and resident phenotypes. Most previous research treats …

Lessons to learn from all out invasion: life history of brown trout (Salmo trutta) in a Patagonian River
… Life history flexibility, and particularly partial migration play a major role in the ability of this species to adapt to Patagonian rivers. Consequently, this study explored habitat, distribution and life history of a partially migratory population of brown trout in the Rio Grande in Tierra …

Ecological genomics and conservation of caribou in Western North America
… within caribou populations, also including partial migration. In this thesis, I identified genes under selection and patterns of population structure that should be considered in conservation planning and management of caribou populations. Habitats and climate are dramatically changing …

The role of intrinsic and extrinsic factors in shaping alternative migratory tactics and metabolic phenotypes in brown trout
… that naturally differ in anadromy (i.e. sea-migration). Food restriction affected traits related to size and condition, and resulted in a higher frequency of anadromy in both populations, though populations varied in their responses according to the timing of food restriction treatments. …

The phylogenetics and evolution of Africa's Larks (Alaudidae)
… and sexually size dimorphic, while nomadism, partial migration, Palearctic or intra-African migration are developed as strategies to adapt to a diet including a large seed component. Desert specialist larks are either resident insectivores or locally nomadic/partially migrant seed-eaters that …
