Declining body size: a third universal response to warming?
A recently documented correlate of anthropogenic climate change involves reductions in body size, the nature and scale of the pattern leading to suggestions of a third universal response to climateExpand
Animal personality: what are behavioural ecologists measuring?
An integrative theoretical framework is suggested that incorporates the tools that were developed to overcome similar methodological problems in psychology to facilitate a robust and unified approach in the study of animal personality. Expand
Complex cooperative strategies in group-territorial African lions
Female lions (Panthera leo) showed persistent individual differences in the extent to which they participated in group-territorial conflict, and modification of the "odds" in these encounters revealed that some females joined the group response when they were most needed, whereas other lagged even farther behind.

The absence of sex-biased dispersal in the cooperatively breeding grey-crowned babbler.
It is concluded that while constraints on independent breeding encourage high rates of philopatry, incest avoidance nonetheless drives high ratesof dispersal by both sexes, indicating that effective dispersal occurs over greater distances and more frequently than recoveries of banded birds indicated.

How not to measure boldness: novel object and antipredator responses are not the same in wild baboons
Boldness in animal personality studies is measured using a range of different behavioural assays, including responses to novel objects, novel environments and threatening stimuli. These assays shouldExpand
Online Localization of Radio-Tagged Wildlife with an Autonomous Aerial Robot System
A novel two-point phased array antenna system that yields unambiguous bearing measurements and an associated uncertainty measure is presented, and estimation and informationbased planning algorithms incorporate this bearing uncertainty to choose observation points that improve confidence in the location estimate.

Boldness, trappability and sampling bias in wild lizards
It is suggested that studies that trap animals for laboratory assessments of personality may consistently underrepresent the extent of personality trait variation in the populations that they sample, and recommend that future studies either develop methods for testing personality in the field that control for obvious confounding variables or make every effort to ensure minimum bias when sampling animals for use in a laboratory setting.

Slow Learning of Foraging Skills and Extended Parental Care in Cooperatively Breeding White-Winged Choughs
Three years of survival data show that juveniles with high numbers of adults to care for them have better prospects of surviving their first year, and it is suggested that juveniles must optimize between acquiring sufficient food from begging and devoting sufficient time to learning to forage. Expand
Social constraint and an absence of sex‐biased dispersal drive fine‐scale genetic structure in white‐winged choughs
It is suggested that genetic structure in white‐winged choughs reflects the interplay between social barriers to dispersal resulting in large family groups that can remain stable over long periods of times, and short dispersal distances which lead to above average relatedness among neighbouring groups.

Overlap and competition for nest holes among eclectus parrots, palm cockatoos and sulphur-crested cockatoos
The extent of overlap in the characteristics of nest holes used by eclectus parrots, palmcockatoos and sulphur-crested cockatoos in patches of rainforest and woodland in and around Iron Range National Park, Cape York Peninsula, Australia is examined to discuss the intense competition between these large parrots in light of the apparent shortage of appropriate nest holes.
