“Milbulgali Bagili”: A systematic scoping review of the history of Aboriginal and Torres Strait Islander advocacy 1940‐1970

Issue addressed: Health promotion, the process of enabling people to increase control over their health, implies advocacy and empowerment on behalf of others. This does not account for the phenomena whereby Aboriginal and Torres Strait Islander people have advocated to strengthen the determinants of their own and their communities' health. This paper provides a systematic scoping review of the published literature that documents Aboriginal and Torres Strait Islander advocacy to improve community empowerment during the time 1940-1970. The objectives of the review were to establish: 1. The extent to which Aboriginal and Torres Strait Islander advocacy has been documented; 2. The extent to which the literature is written from an Aboriginal and Torres Strait Islander perspective; 3. The extent to which local community-level advocacy has been documented; and 4. How advocacy occurred. Methods: The Informit database was systematically searched, publications selected against inclusion criteria, and themes synthesised to map key concepts, types of evidence and gaps in research. Results: Based on this systematic search, 30 papers were found. The four key themes identified were: individual advocates, black organisations, international solidarity and black and white people working together. Conclusions: Despite the many gaps in the literature, there is documented evidence of considerable outcomes from advocacy. So what?: The concept of advocacy and indeed, health promotion itself, may need to be decolonised, and that the concept of “everyday resistance” may more accurately encompass the diverse repertoire of actions which took place between agents of resistance and agents of dominant power</p

Data from: The genetic architecture of ecological adaptation: intraspecific variation in host plant use by the lepidopteran crop pest Chloridea virescens

Intraspecific variation in ecologically important traits is a cornerstone of Darwin’s theory of evolution by natural selection. The evolution and maintenance of this variation depends on genetic architecture, which in turn determines responses to natural selection. Some models suggest that traits with complex architectures are less likely to respond to selection than those with simple architectures, yet rapid divergence has been observed in such traits. The simultaneous evolutionary lability and genetic complexity of host plant use in the Lepidopteran subfamily Heliothinae suggest that architecture may not constrain ecological adaptation in this group. Here we investigate the response of Chloridea virescens, a generalist that feeds on diverse plant species, to selection for performance on a novel host, Physalis angulata (Solanaceae). P. angulata is the preferred host of Chloridea subflexa, a narrow specialist on the genus Physalis. In previous experiments, we found that the performance of C. subflexa on P. angulata depends on many loci of small effect distributed throughout the genome, but whether the same architecture would be involved in the generalist’s adoption of P. angulata was unknown. Here we report a rapid response to selection in C. virescens for performance on P. angulata, and establish that the genetic architecture of intraspecific variation is quite similar to that of the interspecific differences in terms of the number, distribution, and effect sizes of the QTL involved. We discuss the impact of genetic architecture on the ability of Heliothine moths to respond to varying ecological selection pressures

Insect – Tree Interactions in Thaumetopoea pityocampa

The pine processionary moth is, by far, the most important insect defoliator of pine forests in Southern Europe and North Africa, both in terms of its temporal occurrence, geographic range and socioeconomic impact. Monitoring and pest management actions are therefore required on a regular basis, to ensure the detection, evaluation and mitigation of potential risks to forest and public health. However, we still lack some of the basic knowledge required for relevant analyses of the risk posed by the pine processionary moth. Pest risk is defined as a combination of three components: (1) pest occurrence, which depends on the spatiotemporal dynamics of populations; (2) plant vulnerability to the pest, resulting in a certain amount of damage; and (3) the socioeconomic impact of damage, depending on the potential value of the plants damaged (Jactel et al. 2012). The population dynamics of the processionary moth has been extensively studied, in particular within the context of climate change (see Battisti et al. 2014, Chap. 2, this volume). Several studies have recently addressed the question of tree and forest vulnerability to pine processionary attacks but a comprehensive review of evidence was missing. This is the first objective of this chapter. In particular we were interested in a better understanding of the ecological mechanisms responsible for the host tree selection, at both the species and individual tree levels. In a second part we show that pine susceptibility to the pine processionary moth could be reduced by improving forest diversity at different spatial scales. In the last part of this chapter we provide quantitative estimate of the growth losses caused by defoliations of the pine processionary moth. Altogether this information paves the way for quantitative risk analyses on pine processionary moth infestations based on forest growth models
