An analysis of the Human Development Report 2011 : sustainability and equity : a better future for all

__Abstract__ The Human Development Report 2007/2008 about climate change and development made bold arguments concerning human rights and justice for the poor and for disadvantaged populations. However, its policy proposals were not as bold, looking very similar to those of the World Bank's World Development Report 2010. In this article we investigate in which direction the thinking on environment and sustainability by UNDP's Human Development Report Office has evolved since the HDR 2007/2008. A detailed frame and lexical analysis of the HDR 2011 on Sustainability and Equity shows a markedly technocratic direction, largely apolitical and insensitive to human rights issues and justice, giving a diluted successor to the HDR 2007/2008 and now close in perspective to the World Bank. This direction, as well as the little attention to the socio-economic and political barriers to sustainability and to climate change impacts we find in the HDR 2011, has consequences for the poorest sectors of South Africa's society

First Record Of Pogoniopsis Rchb. (orchidaceae: Triphorinae) In Santa Catarina State,southern Brazil

Pogoniopsis is an endemic and myco-heterotrophic orchid genus with only two species in Brazil that can be found growing under dense canopy. Pogoniopsis schenckii is more widely distributed,with records in the states of Bahia,Minas Gerais,Paraná,Pernambuco,Rio de Janeiro,and São Paulo. Here we record P. schenckii for the first time in Santa Catarina state,southern Brazil,in a subtropical broadleaved forest,as well the genus Pogoniopsis itself,expanding its southern distribution limit. In addition,a description and a distribution map of the collected specimens are presented. © 2016 Check List and Authors.12

TRY plant trait database – enhanced coverage and open access

Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits—almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

Native diversity buffers against severity of non-native tree invasions

Determining the drivers of non-native plant invasions is critical for managing native ecosystems and limiting the spread of invasive species1,2. Tree invasions in particular have been relatively overlooked, even though they have the potential to transform ecosystems and economies3,4. Here, leveraging global tree databases5–7, we explore how the phylogenetic and functional diversity of native tree communities, human pressure and the environment influence the establishment of non-native tree species and the subsequent invasion severity. We find that anthropogenic factors are key to predicting whether a location is invaded, but that invasion severity is underpinned by native diversity, with higher diversity predicting lower invasion severity. Temperature and precipitation emerge as strong predictors of invasion strategy, with non-native species invading successfully when they are similar to the native community in cold or dry extremes. Yet, despite the influence of these ecological forces in determining invasion strategy, we find evidence that these patterns can be obscured by human activity, with lower ecological signal in areas with higher proximity to shipping ports. Our global perspective of non-native tree invasion highlights that human drivers influence non-native tree presence, and that native phylogenetic and functional diversity have a critical role in the establishment and spread of subsequent invasions
