Abstract
Although the vocal repertoire of nonhuman primates is strongly constrained by genetic, a growing number of studies evidence socially determined flexibility. According to Snowdon et al. [Social Influences on Vocal Development (University Press, Cambridge, 1997), pp. 234-248], calls with a higher socia...

Abstract
Abuse of toluene-containing volatile solvents by adolescents is a significant public health problem. The present study characterized the long-term behavioural and neurochemical consequences of toluene exposure during adolescence.
Male NMRI mice received one injection per day of either toluene (600 m...

Abstract
In ungulates the process of chemical communication by urinary scent marking has been directly related to reproductive dominance, territorial defense and proximity to resources. The differences in the frequency of urine marking and chemical composition of urine of males Antelope cervicapra before, du...

Abstract
We investigated the effect of nestmateship and body size on mate selection through a choice based assay in the primitively eusocial wasp Ropalidia marginata. A recent study has shown that male and female R. marginata mate with their nestmates and non-nestmates with equal probability if no choice is...

Abstract
We obtained mandibular and maxillary tooth impressions from 95 baboons and analyzed digital images of replicas made from these impressions. We measured tooth wear as the percent dentine exposure (PDE, the percent of the occlusal surface on which dentine was exposed), and we examined the relationship...

Abstract
We investigated female mating behavior in two neighboring multimale-multifemale groups of Alouatta caraya in northern Argentina (27 degrees 20'S-58 degrees 40'W). All adult individuals in each group were marked with identification anklets and ear tags, and followed for five consecutive full days per...

Abstract
We studied nestling conflict over food and its resolution in a joint-nesting species of bird, the Taiwan yuhina (Yuhina brunneiceps). We show that adult yuhinas coordinate their feeding visits, and that this coordination limits competition among nestlings, leading to a 'fairer' division of resources...

We examined predictors of political attitude change by assessing the independent and interactive effect of social dominance orientation (SDO) as a context-dependent versus an individual difference construct. In a longitudinal study, British students' political orientation was assessed before enterin...

Abstract
We show in the angelfish Centropyge bicolor that the rate of overt mild aggression from dominants to subordinates acts as a signal of increasing rank conflict. The clarity of this signal can be reduced by spatial segregation, causing subordinates to be less able to respond appropriately by regulatio...

We have limited understanding of why they have evolved. One possibility is that individuals use previous victories and defeats to assess their fighting ability relative to others. We explored this idea by modelling a population of strong and weak individuals that do not know their own strength, but...

Abstract
We hypothesized that regulation of worker reproduction in R. marginata is mediated by pheromones rather than by physical aggression. Based on the immediate loss of aggression by the PQ upon return of the queen, we developed a bioassay to test whether the queen's Dufour's gland is, at least, one of t...

In support of our hypotheses, we found in Study 1 that autonomous reasons were positiv...

Abstract
The polyphagous drywood termite Kalotermes flavicollis (Fabricius) can establish its colonies inside living trees, causing a progressive debilitation that ends with the death of the plant. For this reason, it is considered one of the major pests of Sherry vineyards in Andalusia, SW Spain. To analyze...

Results were generally, though not uniformly, consistent with...

Abstract
Social rank in cervids and other mammals is not entirely predicted by body weight, but in most cases influences access to food directly. Milk provisioning depends on maternal weight and on daily food intake. Usually, body weight, body condition, age and social rank are inter-correlated making it ver...

Abstract
The binding of [3H]SCH 23390 has been studied in various brain regions of male mice with the experience of repeated victory (winners) or defeat (losers) gained over 10 (T10) and 20 (T20) days of daily agonistic confrontations. In the frontal cortex, B(max) of [3H]SCH 23390 binding sites was found to...
