Differential migration is a widespread, but poorly understood, phenomenon in birds. In this
paper, we present the first detailed field study of differential migration in the Old World …

We contrast patterns of variation in morphological traits of migratory and sedentary forms of
the Yellow-rumped Warbler (Dendroica coronata) to test functional predictions regarding the …

Migration is an energetically expensive and hazardous stage of the annual cycle of non‐
resident avian species, and requires certain morphological adaptations. Wing shape is one …

Divergent selection and local adaptation are responsible for many phenotypic differences
between populations, potentially leading to speciation through the evolution of reproductive …

One of the biggest problems facing the world today is environmental pollution. Soil, water
and air are contaminated by both natural and anthropogenic sources (UNEP, 2008; Hsiao et …

Feathers have a diversity of functions in birds and are costly to produce, so their growth rate
and mass can be reliable indicators of nutritional condition at the time of production. Despite …

Capsule: We assess biometric variation in the threatened Dupont's Lark along a wide
fraction of its distribution area analysing the largest data set for this bird species available to …

El estudio de la migración de aves en España: trayectoria histórica y perspectivas de futuro.
Objetivos: Valorar la importancia de los estudios sobre migración en el desarrollo y estado …

The Japanese horned beetle, Trypoxylus dichotomus septentrionalis, exhibits inter-and
intrasexual dimorphism. Among Japanese horned beetles showing intrasexual dimorphism …

Avian migration strategies may include intra-specific variations, also known as differential
migration. These migratory adaptations between conspecifics are particularly important …
