Extrinsic stressors modulate resource evaluations: insights from territoriality under artificial noise
Competition is considered to rely on the value attributed to resources by animals, but the influence of extrinsic stressors on this value remains unexplored. Although natural or anthropogenic environmental str... (Source: Frontiers in Zoology)

Polymorphism of winter phenotype in Siberian hamster: consecutive litters do not differ in photoresponsiveness but prolonged acclimation to long photoperiod inhibits winter molt
The theory of delayed life history effects assumes that phenotype of adult individual results from environmental conditions experienced at birth and as juvenile. In seasonal environments, being born late in th... (Source: Frontiers in Zoology)

Rosaceae, Brassicaceae and pollen beetles: exploring relationships and evolution in an anthophilous beetle lineage (Nitidulidae, Meligethes-complex of genera) using an integrative approach
Meligethes are pollen-beetles associated with flowers of Rosaceae as larvae. This genus currently consists of 63 known species in two subgenera, Meligethes and Odonthogethes, predominantly occurring in the easter... (Source: Frontiers in Zoology)

Neuroendocrine patterns underlying seasonal song and year-round territoriality in male black redstarts
The connection between testosterone and territoriality in free-living songbirds has been well studied in a reproductive context, but less so outside the breeding season. To assess the effects of seasonal andro... (Source: Frontiers in Zoology)

Heat production in a feeding matrix formed on carrion by communally breeding beetles
Insects regulate their body temperature mostly behaviourally, by changing posture or microhabitat. Usually they use heat that is already present in the environment. Sometimes, however, they may manipulate the ... (Source: Frontiers in Zoology)

Density-dependence of nestling immune function and physiological condition in semi-precocial colonial bird: a cross-fostering experiment
Nesting in large aggregations provides several important advantages for colonially breeding birds. However, it also imposes certain costs, associated with facilitated pathogen transmission and social stress. T... (Source: Frontiers in Zoology)
