Criterios para determinar la edad de pollos de Flamenco Austral (Phoenicopterus chilensis) en cautiverio basadas en características del plumaje [PDF]
, 2018 Many aspects of the breeding biology of the Chilean Flamingo (Phoenicopterus chilensis) are still unknown. We studied captive breeding Chilean Flamingos at La Plata Zoo, Buenos Aires, Argentina between February and July 2014 to document chick‐aging ...

Humans are not unique: difficult birth is common in placental mammals
Biological Reviews, EarlyView.ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Effects of satellite transmitters on captive and wild mallards
Wildlife Society Bulletin, 2014 Satellite telemetry has become a leading method for studying large‐scale movements and survival in birds, yet few have addressed potential effects of the larger and heavier tracking equipment on study subjects.

The costs of extra‐pair behaviours in birds
Biological Reviews, EarlyView.ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Conservation Science and PracticeThe success of avian translocations depends on many factors. Release age is often cited as an influential factor that warrants further study, yet no general guidelines exist to improve the outcome of translocations.

Hand-rearing reduces fear of humans in European starlings, Sturnus vulgaris.
PLoS ONE, 2011 Pending changes in European legislation ban the use of wild-caught animals in research. This change is partly justified on the assumption that captive-breeding (or hand-rearing) increases welfare of captive animals because these practices result in ...

Nutritional and health status of woolly monkeys [PDF]
, 2008 Woolly monkeys (Lagothrix lagotricha and L. flavicauda) are threatened species in the wild and in captivity. Numerous zoological institutions have historically kept Lagothrix lagotricha spp., but only a few of them have succeeded in breeding populations.

Biophysical processes of morphogenesis in lizard lungs
Developmental Dynamics, EarlyView.Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Rapid loss of antipredatory behaviour in captive-bred birds is linked to current avian invasions
Scientific Reports, 2015 Despite the importance of behaviour in conservation biology, there have been few studies that address behaviour in areas such as invasion ecology. There is an urgent need to identify specific traits that facilitate the establishment and spread of alien ...
