How much biotic nativeness matters across human demographic groups
Conservation Biology, EarlyView.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Brazilian Journal of BiologyAmong the vertebrate pollinated plants, the genus Erythrina includes tree species in which birds are the pollen vectors. Two groups in this genus may be distinguished: a) the hummingbird, and b) the perching bird pollinated species. Erythrina dominguezii

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.

Major Transitions in Political Order
, 2016 We present three major transitions that occur on the way to the elaborate and diverse societies of the modern era. Our account links the worlds of social animals such as pigtail macaques and monk parakeets to examples from human history, including 18th ...

Sensory preferences and personality traits of captive red crowned kakariki (Cyanoramphus novaezelandiae) and Antipodes Island parakeets (C. unicolor) : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Zoology at Massey University, Palmerston North, New Zealand [PDF]
, 2017 The way in which most animals sense and interpret the environment around them differs from species to species. Even two closely related species such as the red-crowned parakeet (Cyanoramphus novaezelandiae) and the Antipodes Island parakeet (C. unicolor)

Psittacid herpesvirus 3 infection in rose-ringed parakeets in southern Brazil
Journal of Veterinary Diagnostic Investigation, 2020 We diagnosed disease caused by psittacid herpesvirus 3 (PsHV-3), a novel psittacid pathogen, in rose-ringed parakeets (Psittacula krameri) housed in an exotic psittacine breeding colony in southern Brazil.

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.
