  Prospects for Biodiversity »

  Assuming no radical transformation in human behavior, we can expect important changes in biodiversity and ecosystem services by 2050. A considerable number of species extinctions will have taken place. Existing large blocks of tropical forest will be much reduced and fragmented, but temperate forests and some tropical forests will be stable or increasing in area, although the latter will be biotically impoverished. Marine ecosystems will be very different from today's, with few large marine predators, and freshwater biodiversity will be severely reduced almost everywhere. These changes will not, in themselves, threaten the survival of humans as a species.

  Tracking the ecological overshoot of the human economy »

  Sustainability requires living within the regenerative capacity of the biosphere. In an attempt to measure the extent to which humanity satisfies this requirement, we use existing data to translate human demand on the environment into the area required for the production of food and other goods, together with the absorption of wastes. Our accounts indicate that human demand may well have exceeded the biosphere's regenerative capacity since the 1980s. According to this preliminary and exploratory assessment, humanity's load corresponded to 70% of the capacity of the global biosphere in 1961, and grew to 120% in 1999.

  The HERMES Story »

  Hotspot Ecosystem Research on the Margins of European Seas (HERMES) was one of the 40 most successful projects under the EU's 6th Framework Programme for Research and Technological Development. Following completion of the project in March 2009, The HERMES Story is published jointly by HERMES and UNEP to inform policy and decision makers from around the world about the lessons learned and the amazing new insights into deep-sea biodiversity, structure, function and dynamics discovered under HERMES. The HERMES Story highlights the need for concerted action to protect the deep sea against the increasing pressures, threats and impacts from human activities and climate change, and provides inspiration for the development of similar deep-sea research projects in other regions.

  Designing protected areas to conserve natural resources »

  Biologists view Protected Areas (PAs) as natural areas established and managed primarily for the conservation of nature. However, many early Pas were established for aesthetic or socio-economic reasons and received little scientific input to their design. More recently, scientists have identified gaps in PA networks and various contemporary PAs have been established to provide for habitats and species in need of protection.
  Scientists have also modelled minimum areas and population sizes that should be protected to prevent extinctions arising from demographic or chance causes. However, these theoretical ideals are difficult to put into practice, particularly as PAs increasingly face more immediate external threats. If scientists are to influence future PA design, and if PAs are to succeed in the long term, these concepts must be applied in practice. Therefore, sufficient protection must be integrated with human needs and aspirations in the design of future protected areas.

  Deep-sea biodiversity and ecosystems - a scoping report on their socio-economy, management and governance »

  The deep sea is the oldest and largest biome on Earth, yet we have little knowledge of the ecosystems and processes in these dark, hidden depths. Only in the last two decades have new technologies enabled scientists to start exploring this last frontier – and their discoveries are fascinating but alarming: the deep sea is teeming with life but is already showing clear signs of anthropogenic impacts despite its remoteness. Many vulnerable deep-sea habitats and communities are being destroyed by fishing and are under threat from increasing exploitation of their mineral and living resources.

  Model-based uncertainty in species range prediction »

  Our analyses show significant differences between predictions from different models, with predicted changes in range size by 2030 differing in both magnitude and direction (e.g. from 92 loss to 322 gain). We explain differences with reference to two characteristics of the modelling techniques: data input requirements (presence/absence vs. presence-only approaches) and assumptions made by each algorithm when extrapolating beyond the range of data used to build the model. The effects of these factors should be carefully considered when using this modelling approach to predict species ranges. Main conclusions We highlight an important source of uncertainty in assessments of the impacts of climate change on biodiversity and emphasize that model predictions should be interpreted in policy-guiding applications along with a full appreciation of uncertainty.

  Patterns of isozyme variation as indicators of biogeographic history in Pilgerodendron uviferum (D. Don) Florin »

  The effects of Pleistocene glaciations on the genetic characteristics of the most austral conifer in the world, Pilgerodendron uviferum, were analysed with specific reference to the hypothesis that the species persisted locally in ice-free areas in temperate South America.

  Results indicated that Pilgerodendron populations are highly monomorphic, probably reflecting past population bottlenecks and reduced gene flow. Southernmost populations tend to be the least genetically variable and were therefore probably more affected by glacial activity than northern ones. Populations located outside ice limits seem to have been isolated during the glacial period. The presence of centres of genetic diversity, together with the lack of a significant correlation between genetic and geographical distances and the absence of geographical patterns of allelic frequencies at most analysed alleles, may indicate that Pilgerodendron did not advance southward after the last glaciation from a unique northern refugium, but spread from several surviving populations in ice-free areas in Patagonia instead.

  Protected Area Management Effectiveness Assessments in Europe: A review of application, methods and results (2010) »

  A European Study on protected area management effectiveness assessments was carried out between May 2009 and March 2010, to provide an overview of existing studies, evaluation methods and results. This study was initiated in response to the Global Study’s insufficient coverage of the European sub-region, and as protected area governance in Europe has distinct characteristics that justified a separate analysis. The study was led by the Universities of Greifswald and Queensland, in partnership with UNEP-WCMC, EUROPARC Federation and the German Federal Agency for Nature Conservation (BfN).

  Management Effectiveness Evaluation in Protected Areas – a global study (2nd edition) »

  The Global Study into management effectiveness evaluation was conducted between late 2005 and 2010. In cooperation with many people across the world, it aimed to strengthen the management of protected areas by compiling the existing work on management effectiveness evaluation, reviewing methodologies, finding patterns and common themes in evaluation results, and investigating the most important factors leading to effective management.
