Showing papers in "Animal Behaviour in 2010"

TL;DR: The hypothesis that females choose mates by the evaluation of male motor performance is reviewed, and it is proposed that ornaments often arise secondarily as a way to enhance the apparent skill or vigour ofmale motor performance.

TL;DR: In this article, the authors compared individual behaviour between captivity and the wild in blue tits, Cyanistes caeruleus, and found that exploratory tendency and neophobia measured in captivity positively predicted the analogous traits measured in the wild.

TL;DR: This completely revised second edition of Cognition, Evolution, and Behavior is a unique and wide-ranging synthesis of theory and research on animal cognition, in the broadest sense--from species-specific adaptations of vision in fish and associative learning in rats to discussions of theory of mind in chimpanzees, dogs, and ravens.

TL;DR: In this paper, the authors examined the behavioral responses of the black bean aphid, Aphis fabae, to physiologically relevant doses of volatile compounds emitted by its host, Vicia faba, which had been previously implicated in host recognition.

TL;DR: Here, theory and data are reviewed that argue against hypotheses based exclusively on manipulation or on a fixed, obligatory link between a signal’s physical features and the responses it elicits.

TL;DR: The authors found that men had stronger preferences than women for women's voices with raised pitch (i.e. feminized female voices) and that women had stronger preference than men for men' voices with lowered pitch (e.g. masculinized male voices).

TL;DR: In this paper, a cognitively advanced, social bird, Corvus brachyrhynchos, quickly and accurately learns to recognize the face of a dangerous person and continues to do so for at least 2.7 years.

TL;DR: In this paper, the Ascension Island Turtle Group, Ascension Island, South Atlantic Wildlife Conservation Society, Gabon f Institute of Environmental Sustainability, Swansea University, U.K.A.

TL;DR: Chimpanzees are more sensitive to reward inequity than procedures, and that there is interaction between social and individual expectations that depends upon social factors.

TL;DR: A number of studies suggest that dogs understand human gestures communicatively, as a number of possible low-level explanations have been ruled out.

TL;DR: It is shown that resting time is an important component of animal behaviour that can help us understand extinction risk and geographical distribution of taxa, and that enforced resting time distinguishes between locations that are suitable or unsuitable for particular genera.

TL;DR: By evaluating a priori hypotheses of how behaviours might covary using SEM, it is demonstrated that the two types of populations of three-spined stickleback differed specifically in covariance patterns for aggression, exploration of novel food sources and altered environments, but not for Exploration of novel environments and activity.

TL;DR: In this article, the authors used social network analysis to examine biological correlates of individual social variation in free-living groups of yellow-bellied marmots, Marmota flaviventris.

TL;DR: It is shown that low mate availability can override the effect of all other factors that select for male mate choice and conclude that studies of mate choice should examine why individuals refuse to take advantage of every opportunity, instead of merely focusing on the fact that some opportunities are better than others.

TL;DR: It is found that raising the minimum frequency is common in urban birds and is not restricted to passerine song, but also occurs in other vocalizations of passerines and parrots, indicating that frequency differences between species influence the way in which they respond to the same communication problem, and possibly also the subsequent evolution of acoustic signals.

TL;DR: This article showed that the presence of adults during early development influences the social behaviour of juveniles later on in the cooperatively breeding cichlid Neolamprologus pulcher, and that the social rearing conditions persistently affect the economy and adequacy of individual reactions to social challenges.

TL;DR: Investigation of the association patterns of female bottlenose dolphins in the eastern gulf of Shark Bay, Western Australia found that they depended upon the complex interplay of at least three factors: home range overlap, matrilineal kinships and biparental kinship.

TL;DR: This study presents the performance of one under-represented population, stray dogs living in shelters, on a human-guided object-choice task and finds that shelter dogs universally failed to follow a momentary distal point to a target location in initial tests.

TL;DR: Investigating the components of relationship quality in ravens found that kin had more valuable relationships, whereas females had less secure and compatible relationships, although the effect of sex combination on compatibility only applied to nonkin.

TL;DR: It is suggested that prey species with escape tactics offering little chance of survival following an encounter should seek predator scarcity, whereas those with tactics whose post-encounter effectiveness is spatially correlated with predator abundance should be most likely to match the distribution of their predators.

TL;DR: Kudu was the only species to adjust its vigilance level significantly in the presence of lions, arguably owing to its higher contribution to lion diet in Hwange National Park, Zimbabwe, and the interplay between the context and the immediate presence of predators determines the level of vigilance in prey.

TL;DR: It is shown that USVs are highly diverse among males, but further experiments are needed to determine whether these vocalizations play a role in social (individual, sibling or kin), inbreeding avoidance or other forms of mate choice.

TL;DR: It is shown that captive bonobos and chimpanzees are equally diverse tool-users in most contexts, and that female bonobos displayed a larger range of tool use behaviours than males, a pattern previously described for chimpanzees but not for other great apes.

TL;DR: Overall, positive reinforcement enhanced learning and memorization of the task itself and suggest remarkable social cognitive abilities that can be transposed from intraspecific to interspecific social contexts.

TL;DR: It was found that ants were most attracted to foods with equal or moderately protein-biased p:c ratios, however, colonies on these two treatments created large hoards, and the p:C ratios of these foods differed from that of collected food.

TL;DR: It is proposed that mutual displays at the nest in zebra finches represent private vocal duets and may function to mediate pair bond maintenance.

TL;DR: It is demonstrated that chimpanzees use their ‘greeting’ signals flexibly by taking into account the social fabric of their community, and this behaviour was moderated by social inhibition.

TL;DR: This response to Hare et al. (2010) does not agree that a hypothesis based on genetic inheritance alone is viable without consideration of the interacting developmental and environmental variables that are necessary for the expression of any phenotype.

TL;DR: The results suggest that capuchins discriminate between nuts and between stones, selecting materials that allow them to crack nuts with fewer strikes, and generate exploratory behaviours to discriminate stones of varying mass.
