As urbanization increases, the identification of nest predators becomes important for avian conservation and management of urban wildlife communities. We investigated bird nest predation using artificial nests in urban areas of the KwaZulu-Natal (KZN) Province of South Africa. From June 2013 through February 2014 we installed seventy-five artificial nests in 25 suburban gardens in the Ethekwini and Msunduzi municipalities of KZN. Euplectes spp. nests were used and baited with two quail-sized, hand-made, silicon eggs. These were placed in residential gardens and monitored by camera traps for 2-weeks in winter, spring and summer respectively. Generally bird nesting occurs throughout the year in KZN’s subtropical climate, with some avoidance during the autumn season. Therefore, experiments were not conducted during autumn, as fresh nests were not available for use. Overall the rate of predation on artificial nests was 25 % (n = 19), with vervet monkeys Ceropithecus aethiops pygerythrus predating 20 % (n = 17) of the nests while domestic cats Felis catus predated 3 % (n = 2) of nests. Nest predation was significantly higher in the winter season, with 79 % of depredations occurring in winter (n = 15), 16 % in spring (n = 3) and 5 % in summer (n = 1), and in areas with less canopy cover. Our results suggest that vervet monkeys may have a negative impact on nesting birds in urban environments, however, in order to assess the rate of predation experiments on natural nests coupled with information on fledgling success is deemed necessary to investigate avian population declines.  相似文献

The availability of knowledge translation strategies that have been empirically studied and proven useful is a critical prerequisite to narrowing the research-to-practice gap in child and youth mental health. Through this review the authors sought to determine the current state of scientific knowledge of the effectiveness of knowledge translation approaches in child and youth mental health by conducting a systematic review of the research evidence. The findings and quality of the 12 included studies are discussed. Future work of high methodological quality that explores a broader range of knowledge translation strategies and practitioners to which they are applied and that also attends to implementation process is recommended.  相似文献

In this article, we explore the lived experience of avoiding environmental chemicals through safer consumption, such as buying “eco‐friendly” products. Using focus groups and in‐depth interviews involving 50 subjects, we investigate how individuals become aware of environmental chemicals and how they adapt to this awareness. Our participants describe being surprised or alarmed to learn that chemicals are present in food and commodities that they believed were safe. They respond by developing a set of heuristics rendering the “dangerous” consumer landscape into a space that is amenable to personal control. They learn to read an ingredient label and look for organic certification seals on product packaging. We develop the idea of the “contingent boundary” to describe how participants perceive personal control as uneven: they believe they can activate a protective boundary in local and familiar contexts, but outside these contexts, they believe the boundary dissolves. They accept this contingency as normal and describe having to ignore some chemical exposures, for fear of becoming too “crazy.” We conclude that the individuals in our study accept that inverted quarantine (Szasz 2007) is out of reach, and instead try to impose order upon a ubiquitous risk.  相似文献

The CANparent trial, 2012–2014, was a government initiative in four English areas designed to develop a market in universal parenting support. Fourteen parenting class providers offered classes to all parents of children aged 0–5 in the areas. In three areas, all eligible parents received £100 vouchers exchangeable for a parenting class. Pre‐trial planning was that take‐up would amount to 20 000 parents. However, only 14 per cent of these parents took advantage of the offer. This article utilises 42 interviews with providers, and two parent surveys over two time periods (n = 1510 and n = 1603) to review barriers to engagement with universal parenting support programmes.  相似文献
