Boldness predicts foraging behaviour, habitat use and chick growth in a central place marine predator
Animal personality can shape individual’s fitness. Yet, the mechanistic relationship by which individual’s personality traits lead to variations in...

Cooperative parental performance at chick provisioning in a small passerine, the Reed Warbler Acrocephalus scirpaceus
AbstractSexual conflict has long been perceived as a solid background for the evolution of parental care. Recent studies, however, highlight the...

Leach’s storm-petrel (Hydrobates leucorhous), a long-lived seabird shows flexible, condition-dependent, feeding strategies in response to poor chick condition
BackgroundParent-offspring conflict represents the sensitive balance of resource allocation between self-maintenance and reproduction. Two strategies...

Sex ratio and sex-specific chick mortality in a species with moderate sexual size dimorphism and female brood desertion
An equal sex ratio at the population level is the usual, evolutionarily stable condition. However, at the individual level, it may be adaptive for...

The effect of storage periods and SPIDES on embryonic mortality, hatching characteristics, and quality of newly hatched chicks in broiler eggs
Egg storage duration can affect embryo mortality, hatching characteristics, hatching time, and post-hatch chick quality. In order to assess these...

Cross-continental differences in Black-tailed Godwit breeding densities are best explained by arthropod abundance in the chick-hatching period
The endangered continental Black-tailed Godwit ( Limosa limosa limosa ) is a migratory ground-nesting wader breeding in a wide variety of open, wet...

Influence of management practice on the microbiota of a critically endangered species: a longitudinal study of kākāpō chick faeces and associated nest litter
BackgroundThe critically endangered kākāpō is a flightless, nocturnal parrot endemic to Aotearoa New Zealand. Recent efforts to describe the...

Variation in the trophic niche and food provisioning between the early and late chick-rearing stages in Magellanic penguins Spheniscus magellanicus at Martillo Island, Tierra del Fuego, Argentina
Variation in the foraging niche and parental provisioning behaviors of breeding seabirds have the potential to affect population dynamics (e.g....

Chick Embryo Ex Vivo Aortic Sprouting Assays for Cardiovascular Research
Angiogenesis is the formation of new blood vesicles and is controlled by a dynamic cascade of molecular and cellular activities. The whole procedure...

Multidimensional niche differentiation of chick-rearing sympatric auks in the Gulf of St. Lawrence
Niche theory predicts that similar species cannot occupy the same geographical space when resources are limited. Sympatric seabirds, such as auks,...

Food supply and individual quality influence seabird energy expenditure and reproductive success
Breeding animals trade off maximizing energy output to increase their number of offspring with conserving energy to ensure their own survival,...

Differential Incubation Temperature Effects on Growth of Hisex Brown Chick Embryos and Development of Their Visceral Organs
AbstractSurveys were carried out in order to study the effects of differential incubation temperatures (37.8, 39.5, 37.5, and 37.0°C on days 1–14,...

Intraspecific trophic variation during the early chick-rearing period in Magellanic penguins Spheniscus magellanicus: influence of age and colony location
Intraspecific competition for food resources has the potential to be high for central-place foragers such as penguins and can result in spatial and...

Spatial and temporal aggregation of albatross chick mortality events in the Falklands suggests a role for an unidentified infectious disease
In the context of environmental change, determining the causes underpinning unusual mortality events of vertebrate species is a crucial conservation...

Heat-related massive chick mortality in an Imperial Cormorant Leucocarbo atriceps colony from Patagonia, Argentina
Climate change has exacerbated the frequency and severity of heat waves, which on occasion lead to mass mortalities. Here, we report a massive...

Phenology and reproductive biology of the southern rockhopper penguin (Eudyptes chrysocome chrysocome) at Isla **üino (Santa Cruz Province, Argentina)
An essential trait in the life history of any animal species is reproduction, including parental care. In seabirds, these actions are well defined...
