When and why to give shorebirds a head start

Conservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

How sex-biased dispersal affects conflict over parental investment [PDF]

, 2016
This article is a preprint and has not been peer-reviewed. It is availble from bioRxiv via the DOI in this record.Existing models of parental investment have mainly focused on interactions at the level of the family, and have paid much less attention to

Variable social organization and breeding system of a social parrot revealed by genetic analysis

Ibis, EarlyView.
Social organization and contributions to reproduction vary widely within and between species that breed in groups. Such variation often arises from the process of group formation, which drives patterns of relatedness and hence the degree of social conflict and co‐operation between group members.

Sex‐biased dispersal in the Arabian babbler (Argya squamiceps)

Ibis, EarlyView.
Sex‐biased dispersal plays a central role in shaping social structure and reproductive strategies in many bird species. In the Arabian Babbler Argya squamiceps, a cooperatively breeding species with pronounced male philopatry, dispersal occurs individually or in kin‐based same‐sex coalitions.

No sex-biased dispersal in a primate with an uncommon social system-cooperative polyandry. [PDF]

, 2014
An influential hypothesis proposed by Greenwood (1980) suggests that different mating systems result in female and male-biased dispersal, respectively, in birds and mammals.

Philopatry and Dispersal Patterns in Tiger (Panthera tigris)

PLoS ONE, 2013
Tiger populations are dwindling rapidly making it increasingly difficult to study their dispersal and mating behaviour in the wild, more so tiger being a secretive and solitary carnivore.We used non-invasively obtained genetic data to establish the presence of 28 tigers, 22 females and 6 males, within the core area of Pench tiger reserve, Madhya ...

Reproductive consequences of mate retention and divorce in a short‐lived migratory passerine

Ibis, EarlyView.
In socially monogamous birds, pair‐bond duration varies across species, from single‐breeding associations to long‐lasting, multi‐year bonds. Studies of pair retention and divorce have focused on long‐lived and sedentary species rather than short‐lived and migratory species.

Fine‐scale genetic structure in co‐operatively breeding Palmchats (Dulus dominicus) suggests mixed kinship in compound nests

Ibis, EarlyView.
Fine‐scale genetic structure in animal populations can create opportunities for both kin‐directed co‐operation and kin competition. Knowledge of kinship is therefore key to understanding the selective pressures shaping sociality as well as the effects of social behaviour on local genetic structure.

The Evolution of Primate Societies - Chapter 3 [PDF]

, 2012
Compared with other primates, New World monkeys display relatively limited ecological variability. New World monkey anatomy and social systems, however, are extremely diverse.

Collectivism–Individualism, Family Ties, and Philopatry [PDF]

, 2014
As predicted by the parasite-stress theory of values, variation in parasite stress correlated with collectivism–individualism across nations, USA states, and indigenous societies. In regions with high adversity of infectious diseases, human cultures are characterized by high collectivism, whereas in regions of low parasite stress cultures are highly ...
