Online and offline representations of biocultural diversity: A political ecology perspective on nature-based tourism and indigenous communities in the Brazilian Pantanal
The concept of biocultural diversity is confronted with contemporary changes that impact
on local communities, such as globalization and digital transformations. Engaging the conceptual
flexibility of âbiocultural diversityâ, we studied nature-based tourism at the intersection of indigenous
communities and the digital realm. We employed a political ecology perspective to examine online
and offline representations of biocultural diversity in the Brazilian Pantanal, one of the biggest
wetlands in the world, and home to groups of peoples known as the Pantaneiros. Data from
interviews with 48 stakeholders in the tourist sector were structured along three âmythsââthe
Uncivilised, Unrestrained, and Unchangedâfor which we have also constructed counter narratives.
Each myth denoted the primacy of biodiversity, and ignored broader dimensions of the Pantanal
as a bioculturally diverse landscape. The relationships of the Pantaneiros with their environment
were found to be intricate and had clear repercussions for tourism, but ironically, reference to the
Pantaneiro culture in nature-based tourism was superficial. Moreover, thriving on the myths, this
form of tourism perpetuates skewed power structures and social inequalities. Lower-class Pantaneiros
likely suffer most from this. We recommend stakeholder engagement with a biocultural design that
facilitates the integration of other-than-biodiversity values, and that thereby promotes sustainability
of the entire social-ecological system
Framing the private land conservation conversation: Strategic framing of the benefits of conservation participation could increase landholder engagement
How conservation messages are framed will likely impact on the success of our efforts to engage people in conservation action. This is highly relevant in the private land conservation (PLC) sector given the low participation rates of landholders. Using a case study of PLC schemes targeted at Australian landholders, we present the first systematic analysis of communication strategies used by organisations and government departments delivering those schemes to engage the public. We develop a novel approach for analysing the framing of conservation messages that codes the stated benefits of schemes according to value orientation. We categorised the benefits as flowing to either the landholder, to society, or to the environment, corresponding to the egoistic, altruistic and biospheric value orientations that have been shown to influence human behaviour. We find that messages are biased towards environmental benefits. Surprisingly, this is the case even for market-based schemes that have the explicit objective of appealing to production-focussed landholders and those who are not already involved in conservation. The risk is that PLC schemes framed in this way will fail to engage more egoistically oriented landholders and are only likely to appeal to those most likely to already be conservation-minded. By understanding the frame in which PLC benefits are communicated, we can begin to understand the types of people who may be engaged by these messages, and who may not be. Results suggest that the framing of the communications for many schemes could be broadened to appeal to a more diverse group (and thus ultimately to a larger group) of landholders
Possible biotic interactions that are affecting the presence of Aedes albopictus (Diptera: Culicidae) in Misiones, Argentina
In Argentina, despite local Aedes albopictus presents a certain degree of egg dormancy that would allow to be present at temperate latitudes its distribution is limited to two provinces with a subtropical climate: Misiones and Corrientes. Therefore, it is possible that other factors are limiting the expansion of this vector. To evaluate possible interactions that are affecting population and spread of this specie, we sampled artificial breeding site in Eldorado (urban environment) and Colonia Aurora (rural environment), Misiones province, in October 2015, April and November 2016 and April 2017.Para acceder a la videoconferencia completa, hacer clic en "Enlace externo".Sociedad Latinoamericana de EcologĂa de Vectore

Mesenchymal stem cells from tumor microenvironment favour breast cancer stem cell proliferation, cancerogenic and metastatic potential, via ionotropic purinergic signalling
Interaction between tumor cells and the microenvironment is key in initiation, progression, and invasiveness of cancer. In particular, mesenchymal stem cells (MSCs) are recruited to the sites of developing tumors, thus promoting metastasis formation. Although it is well known that MSCs migrate and integrate in the tumor microenvironment (TME), their fate and function inside the tumor is still not clear. In this study, we analyzed the role played by MSCs in breast cancer oncogenesis. Data indicate that interaction of breast cancer cells with MSCs results in an increased proliferation and metabolic activity of breast cancer cells, partially due to MSC-derived microvesicles that are shed in the TME. Moreover, we addressed the question of whether we could modulate such interaction by acting on P2X-mediated intercellular communication. By inhibiting P2X-mediated purinergic signaling, we succeeded in reducing both the cancerogenic as well as the metastatic potential of breast cancer cells co-cultured with MSCs, in 2D as well as in 3D in vitro models. Data obtained demonstrate for the first time that the trophic effect of MSCs on breast cancer cell growth is exerted via ionotropic purinergic signaling, thus suggesting the inhibition of the purinergic signaling system as a potential target for therapeutic intervention
A systematic review of the literature on the effectiveness of exercise therapy for groin pain in athletes
<p>Abstract</p> <p>Background</p> <p>Athletes competing in sports that require running, changes in direction, repetitive kicking and physical contact are at a relatively higher risk of experiencing episodes of athletic groin pain. To date, there has been no systematic review that aims to inform clinicians about the best available evidence on features of exercise interventions for groin pain in athletes. The primary aim of this systematic review was to evaluate the available evidence on the effectiveness of exercise therapy for groin pain in athletes. The secondary aim of this review was to identify the key features of exercise interventions used in the management of groin pain in an athletic population.</p> <p>Methods</p> <p>MEDLINE, CINAHL, PubMed, SPORTSDiscus, Embase, AMED, Ovid, PEDro, Cochrane Controlled Trials Register and Google Scholar databases were electronically searched. Data relating to research design, sample population, type of sport and exercise intervention was extracted. The methodological evaluation of included studies was conducted by using a modified quantitative critical appraisal tool.</p> <p>Results</p> <p>The search strategy identified 468 studies, 12 of which were potentially relevant. Ultimately five studies were included in this review. Overall the quality of primary research literature was moderate, with only one randomised controlled trial identified. All included studies provided evidence that an exercise intervention may lead to favourable outcomes in terms of return to sport. Four of the five studies reviewed included a strengthening component and most utilised functional, standing positions similar to those required by their sport. No study appropriately reported the intensity of their exercise interventions. Duration of intervention ranged from 3.8 weeks to 16 weeks. All five studies reported the use of one or more co-intervention.</p> <p>Conclusion</p> <p>Best available evidence to date, with its limitations, continues to support common clinical practice of exercise therapy as a key component of rehabilitation for groin pain in athletes. Overall, the available evidence suggests that exercise, particularly strengthening exercise of the hip and abdominal musculature could be an effective intervention for athletes with groin pain. Literature provides foundational evidence that this may need to be in the form of progressive exercises (static to functional) and performed through range. There is currently no clear evidence regarding the most effective intensity and frequency of exercise, because of a lack of reporting in the primary literature.</p
Using technology to improve the management of development impacts on biodiversity
Funder: The research was funded through a longâterm collaboration between Conservational International and Chevron.Abstract: The mitigation hierarchy (MH) is a prominent tool to help businesses achieve no net loss or net gain outcomes for biodiversity. Technological innovations offer benefits for business biodiversity management, yet the range and continued evolution of technologies creates a complex landscape that can be difficult to navigate. Using literature review, online surveys, and semiâstructured interviews, we assess technologies that can improve application of the MH. We identify six categories (mobile survey, fixed survey, remote sensing, blockchain, data analysis, and enabling technologies) with high feasibility and/or relevance to (i) aid direct implementation of mitigation measures and (ii) enhance biodiversity surveys and monitoring, which feed into the design of interventions including avoidance and minimization measures. At the interface between development and biodiversity impacts, opportunities lie in businesses investing in technologies, capitalizing on synergies between technology groups, collaborating with conservation organizations to enhance institutional capacity, and developing practical solutions suited for widespread use
