The purpose of this study was to examine how sex workers rights organizations use their websites as a site of activist and advocacy work and ask (i) how do various organizations conceptualize sex work on their websites, and to what extent do they incorporate an intersectional feminist perspective? (ii) what communication strategies are used by the four organizations to target audiences in the viewing public? (iii) what audiences do the four websites target? (iv) how do the four organizations discuss successes and challenges on their websites? (v) in what ways do sex worker right organizations use websites to further their goals? The websites of Maggie’s, POWER, and Stella attempt to embrace an intersectional feminist perspective of sex work, while PACE does not. The four organizations strategically use their websites to target audiences with diverse needs, specifically through advocacy efforts in educating the general public about the legitimacy of sexual labour. Additionally, to increase the use of the websites by sex workers, using social media platforms, such as Facebook and Twitter augment the untapped potential for creating action, mobilization, interaction, and dialogue on the websites.

This chapter provides an introductory overview of how the term ‘community’ has been conceptualized in sociological literatures, noting that there remains considerable uncertainty with regard to the way in which communities could or should be defined. The chapter examines the salience of underlying concepts of social organization that can shape and influence the extent to which programmes of engagement are likely to be successful. Drawing on recent empirical work some of the key opportunities and challenges for local government in translating the concepts into practice are considered.

Social organization is an important component of the population biology of a species that influences gene flow, the spatial pattern and scale of movements, and the effects of predation or exploitation by humans. An important element of social structure in mammals is group fidelity, which can be quantified through association indices. To describe the social organization of marine tucuxi dolphins (Sotalia guianensis) found in the Cananeia estuary, southeastern Brazil, association indices were applied to photo-identification data to characterize the temporal stability of relationships among members of this population. Eighty-seven days of fieldwork were conducted from May 2000 to July 2003, resulting in direct observations of 374 distinct groups. A total of 138 dolphins were identified on 1-38 distinct field days. Lone dolphins were rarely seen, whereas groups were composed of up to 60 individuals (mean +/- 1 SD = 12.4 +/- 11.4 individuals per group). A total of 29,327 photographs were analyzed, of which 6,312 (21.5%) were considered useful for identifying individuals. Half-weight and simple ratio indices were used to investigate associations among S. guianensis as revealed by the entire data set, data from the core study site, and data from groups composed of <= 10 individuals. Monte Carlo methods indicated that only 3 (9.3%) of 32 association matrices differed significantly from expectations based on random association. Thus, our study suggests that stable associations are not characteristic of S. guianensis in the Cananeia estuary.

The present study was carried out under field conditions in Rio Claro, Southeastern Brazil. The following average life-spans of adults of Mischocyttarus cerberus styx were observed: queens 191.1 days, workers 14.0 days, and males 10.7 days. The short longevity of workers is attributed to the early foraging activity which was performed since the first week of adult age. The life table of the workers revealed high mortality rates during the first three weeks of life. Twenty-four behavioral categories were reported for these wasps and a comparative behavioral catalogue showed that the solitary foundresses (pre-emergence stage) are significantly more active than the queens (post-emergence stage) because they have to perform all the tasks for the nest maintenance. On the other hand, the queens were highly active even in the presence of the workers. The small number of individuals on the nest was the probable cause of the high activity of the queens in the post-emergence colonies. There was no clear division of tasks among workers according to their age (in weeks), so that most of the behavior categories were potentially performed by any worker of any age. Dead queens were replaced by their daughters.

We studied the Red-billed Currasow (Cray blumenbachii) in Vale Natural Reserve, Linhares, Espirito Santo State, Brazil, using camera traps. We found the Red-billed Curassow present in the entire area of the reserve (similar to 22,000 ha) during 40 months of camera trapping (2005-2008). Most records were of single individuals, especially males, but pairs and even groups of individuals were also recorded. Males were paired with one and two females, suggesting polygyny in the species. The species was recorded throughout the day with one peak from 0500 to 0600 hrs and another after 1600 hrs. The daily activity pattern was similar for males and females. The number and widespread nature of the records suggests the local population of this species may be higher than previously thought. Received 10 March 2011. Accepted 5 December 2011.

A central issue in evolutionary biology is the extent to which complex social organization is under genetic control. We have found that a single genomic element marked by the protein-encoding gene Gp-9 is responsible for the existence of two distinct forms of social organization in the fire ant Solenopsis invicta. This genetic factor influences the reproductive phenotypes and behavioral strategies of queens and determines whether workers tolerate a single fertile queen or multiple queens per colony. Furthermore, this factor affects worker tolerance of queens with alternate genotypes, thus explaining the dramatic differences in Gp-9 allele frequencies observed between the two social forms in the wild. These findings reveal how a single genetic factor can have major effects on complex social behavior and influence the nature of social organization.
