“…At an international scale, the representativeness approach has arisen from the need to assess the effectiveness of ecosystem protection, establish conservation priorities and guide investment (Brooks et al 2006). Using ecoregions as classification units at the global scale (Dinerstein et al 1995;Olson & Dinerstein 2002), zones of high biodiversity and endemism have been identified globally (Myers et al 2000;Mittermeier et al 2004;Kier et al 2005;Lamoreaux et al 2006), and their protected status evaluated (Hoekstra et al 2005). Several studies have applied representativeness assessment for setting conservation priorities at global (Chape et al 2003(Chape et al , 2005Rodrigues et al 2004a, Jenkins & Joppa 2009) and country or regional scales (Powell et al 2000;Sierra et al 2002;Arango et al 2003;Armenteras et al 2003;Oldfield et al 2004;Dietz & Czech 2005;López & Zambrana-Torrelio 2006;Soutullo & Gudynas 2006;Maiorano et al 2007;Schulman et al 2007;Brugiere & Kormos 2009;Wiersma & Nudds 2009).…”

SUMMARYBecause protected areas are a major means of conservation, the extent to which ecosystems are represented under different protection regimes needs to be ascertained. A gap analysis approach was used to assess the representativeness of Chile's terrestrial ecosystems in differing kinds of protected areas. Terrestrial ecosystems were described in terms of potential vegetation, employing three protection scenarios. Scenario 1 was based exclusively on the Chilean National System of Protected Wild Areas (SNASPE). Scenario 2 included all types of public protected areas, namely SNASPE, nature sanctuaries and Ministry of National Heritage lands. Scenario 3 included all items in Scenario 2, but also included private protected areas and biodiversity priority sites. There is insufficient protection of terrestrial ecosystems under the Scenario 2. In addition to the low level of ecosystem protection provided by state protected areas (only 42 of the 127 terrestrial ecosystems had >10% of their area protected), 23 terrestrial ecosystems were identified as having no protection at the national level. Gaps in protection were concentrated in the North (both coastal and inland desertic scrub), Central (thorny scrub, thorny forests, sclerophyllous forests and deciduous coastal forests) and Austral (steppe ecosystems) regions of Chile. These gaps include ecosystems that are of global conservation importance.

The vegetation type used was that mentioned in the original work on the pollination ecology of each species, except for cases where the vegetation was not described, and, in this case ecoregions from the world system were used instead (Olson & Dinerstein 2002).

Vegetation types for the localities where pollination studies were performed, when not described in the respective papers, were inferred by assembling the geographic coordinates of the study site with the WWF map of ecoregions (Olson & Dinerstein 2002) in DIVA-GIS (Diva-Gis, 2011).…”

-DOS-SANTOS, I. Floral-oil-producing Plantaginaceae species: geographical distribution, pollinator rewards and interactions with oil-collecting bees. Biota Neotrop. 13(4): http://www. biotaneotropica.org.br/v13n4/en/abstract?article+bn01313042013Abstract: Floral oils as reward to pollinators occur in eleven plant families and appeared at least 28 times in the evolutionary history of flowering plants. They are produced in epithelial or tricomatic glands and collected by oil bee visitors. The present paper focuses on floral-oil-producing species of Plantaginaceae, a Neotropical group namely Angelonia clade. This group comprises around 40 described species in the genera Angelonia, Basistemon , Monttea , Monopera and the oil-less Melosperma . We present a revision of all species of the Angelonia clade, their geographical distribution, resources offered to pollinators and records of flower visitors, especially oil-collecting bees. These plants rely only on oil-collecting species in the tribe Centridini and Tapinotaspidini for a successful pollination, being the interaction between both partners an especial case of bee/flower adaptation in Neotropical region. Some bee species depend only on the oil of Plantaginaceae flowers to survive, while others can collect on several floral oil sources. The pollinating bees explore the oil glands located in sacs using specialized hairs in the forelegs. With this study, we hope to inspire further research relating to this fascinating group of plants, in which most species are rare and occur in highly endangered habitats in South American open vegetation biomes. keywords: plant-insect interactions, oil-collecting bees, oil-flowers, Plantaginaceae, Apidae.

“…Galápagos was one of the first sites on UNESCO's World Heritage List (listed in 1978) and has been identified as one of the 137 'most irreplaceable protected areas' in the world (Le Saout et al 2013), as well as a 'flagship' area for conservation (González et al 2008) and a Priority Ecoregion for Global Conservation (Olson and Dinerstein 2002). The uniqueness of the islands led the Ecuadorian Government to create the Galápagos National Park in 1959.…”

Galápagos is one of the most pristine archipelagos in the world and its conservation relies upon research and sensible management. In recent decades both the interest in, and the needs of, the islands have increased, yet the funds and capacity for necessary research have remained limited. It has become, therefore, increasingly important to identify areas of priority research to assist decision-making in Galápagos conservation. This study identified 50 questions considered priorities for future research and management. The exercise involved the collaboration of policy makers, practitioners and researchers from more than 30 different organisations. Initially, 360 people were consulted to generate 781 questions. An established process of preworkshop voting and three rounds to reduce and reword the questions, followed by a two-day workshop, was used to produce the final 50 questions. The most common issues raised by this list of questions were human population growth, climate change and the impact of invasive alien species. These results have already been used by a range of organisations and politicians and are expected to provide the basis for future research on the islands so that its sustainability may be enhanced.
