Self Harm

Abstract. Background: Indigenous Australians experience a suicide rate over twice that of the general population. With nonfatal deliberate self-harm (DSH) being the single most important risk factor for suicide, characterizing the incidence and repetition of DSH in this population is essential. Aims: To investigate the incidence and repetition of DSH in three remote Indigenous communities in Far North Queensland, Australia. Method: DSH presentation data at a primary health-care center in each community were analyzed over a 6-year period from January 1, 2006 to December 31, 2011. Results: A DSH presentation rate of 1,638 per 100,000 population was found within the communities. Rates were higher in age groups 15–24 and 25–34, varied between communities, and were not significantly different between genders; 60% of DSH repetitions occurred within 6 months of an earlier episode. Of the 227 DSH presentations, 32% involved hanging. Limitations: This study was based on a subset of a larger dataset not specifically designed for DSH data collection and assesses the subset of the communities that presented to the primary health-care centers. Conclusion: A dedicated DSH monitoring study is required to provide a better understanding of DSH in these communities and to inform early intervention strategies.

Care Problems

The rural Kumiai community of San Antonio Necua is one of the few remaining indigenous communities in Baja California, Mexico. Necuan health and health care problems are best understood through a consideration of the effects of colonialism and marginalization on indigenous groups in northern Baja California as well as a tradition of medical pluralism in Mexico. The lack of traditional healers and biomedical providers in the community, high rates of preventable or manageable illnesses, and a blend of biomedical, folk mestizo, and traditional indigenous beliefs about health and illness reflect current conditions of rural poverty and economic isolation. Descriptions of health and health care problems are based on ethnographic fieldwork among the Kumiai, their Paipai relatives, and their primary nongovernmental aid organization.

Species Abundances

Biodiversity and ecosystem function are often correlated, but there are multiple hypotheses about the mechanisms underlying this relationship. Ecosystem functions such as primary or secondary production may be maximized by species richness, evenness in species abundances, or the presence or dominance of species with certain traits. Here, we combined surveys of natural fish communities (conducted in July and August, 2016) with morphological trait data to examine relationships between diversity and ecosystem function (quantified as fish community biomass) across 14 subtidal eelgrass meadows in the Northeast Pacific (54° N 130° W). We employed both taxonomic and functional trait measures of diversity to investigate if ecosystem function is driven by species diversity (complementarity hypothesis) or by the presence or dominance of species with particular trait values (selection or dominance hypotheses). After controlling for environmental variation, we found that fish community biomass is maximized when taxonomic richness and functional evenness is low, and in communities dominated by species with particular trait values – those associated with benthic habitats and prey capture. While previous work on fish communities has found that species richness is positively correlated with ecosystem function, our results instead highlight the capacity for regionally prevalent and locally dominant species to drive ecosystem function in moderately diverse communities. We discuss these alternate links between community composition and ecosystem function and consider their divergent implications for ecosystem valuation and conservation prioritization.
