Abstract: Ecological infrastructures (EIs) are considered relevant components in agricultural landscapes to support bio ersity and ecosystem services. We used the predatory attacks on lepidopteran dummies as a proxy to assess predation rates in the agricultural matrix and different EIs types according to their location and vegetation structure. We aimed at comparing the effect of different types of EI on the predation intensity in two intensively irrigated agricultural areas located in the Sorraia and Tagus river valleys in central Portugal. We hypothesized that: (1) the predation rate would be higher near EIs compared with the agricultural matrix, (2) the positive effect of EIs on predation rate would differ with their typologies, and (3) the EIs’ proximity and proportion in the surrounding landscape would have a positive effect on the predation rate in agricultural fields. The EI typologies influenced differently the predator groups and the overall predation rate. Major differences were observed for bird predation, being higher in woody EIs. A positive correlation between predation rate and EIs area of the surrounding landscape, as well as a negative correlation with the distance to the nearest riparian and woody EIs, was observed for birds. The observed dissimilarities in the predators’ response may be related to habitat differences and its functional connectivity. The overall monthly low predation rates are possibly related to the intensive agricultural system and the small area occupied by EIs.

Abstract: Understanding how countries’ future development pathways could affect forests can help to avoid negative impacts and instead promote positive ones. Exploring this topic requires knowledge of which areas of the development agenda are likely to show the greatest progress, and how these expected changes relate to the drivers of deforestation and forest degradation that are currently affecting forests, or which may emerge as result of development-related changes. Based on this information, researchers, stakeholders and decisionmakers can engage in discussions to inform further research and interventions. We present an assessment framework that draws upon a range of data types to identify specific components of the development agenda that are likely to be of greatest relevance to forest conservation at the national level. We then assess the potential magnitude and likelihood of imminent changes in these areas over the short- to medium-term. We use this framework to assess 48 tropical countries, providing insights into the areas of sustainable development that are most likely to provide risks, opportunities or enabling conditions for forest conservation across much of the tropics. Our findings suggest that, across much of the tropics, ongoing risks to forests associated with agriculture, transport infrastructure and urban infrastructure could worsen, and that new risks from energy infrastructure could emerge. Opportunities relating to poverty reduction, tourism, and industry, among others, will require care to ensure that associated progress results in positive rather than negative forest impacts. Enabling conditions associated with, inter alia, improved education, inclusive decision-making, and effective governance, still have much room for improvement, and the anticipated likelihood of imminent progress in these areas varies between countries and regions. We discuss the implications of our findings for policymakers and development agencies, and consider potential future applications of our assessment protocol.

Abstract: In Brazil most of the effort for the conservation of plant species has comprised evaluation of taxa for the Lista Oficial das Espécies Ameaçadas de Extinção da Flora Brasileira (Official Threatened Flora Species List), and little has been done to conserve in idual species. This is a result of the listing process being interpreted as the final goal rather than as a means to achieve conservation effectiveness. In addition, a variety of systems for the classification of extinction risk have been applied, resulting in an inaccurate view of the conservation status of the flora of the country. Here we review the national listing process to highlight the strengths and weaknesses of the Official Threatened Flora Species List. We used all available information to compile a list of taxa officially recorded as threatened in Brazil. The list was revised using the Flora do Brasil database. The resulting list has 4,967 taxa in 1,235 genera and 232 families. Despite controversies about advances in the Red Listing process, several improvements have been made at the institutional level, such as: (1) improving conservation databases, (2) developing information systems, and (3) increasing the number of taxonomists working in conservation biology. However, there is still no classification system for extinction risk that facilitates standardization of the listing process at the national level. In addition, regulatory processes related to the conservation of threatened plant species are not up-to-date with the conceptual and methodological advances made by the scientific community. We conclude that adjustments are needed to ensure the effectiveness of the conservation of plant species in Brazil.
