  • Select Terrestrial, Freshwater and Marine Conservation Targets/Biodiversity Elements/Features Across Multiple Biological and Spatial Scales
    Standard 7: Select terrestrial, freshwater and marine conservation targets/biodiversity elements/features across multiple biological and spatial scales. [plan] Rationale It is necessary to define a subset of targets that best represent the biodiversity of an ecoregion to focus the assessment. Conservation targets should cover the suite of biological scales (species to communities, ecological systems and other targets), taxa, and ecological characteristics to adequately inform comprehensive biodiversity conservation. Targets should include coarse and fine filter targets. This includes using rare and endangered, wide ranging, migratory and keystone species, rare communities, and all ecological systems and/or ecosystem types, as well as additional targets that are useful in capturing the variety of biodiversity characteristics, scales and ecological processes. Recommended Products ,,,List, and attributes of fine-filter targets such as distribution (local, widespread), conservation status (threatened and endangered), endemic, wide-ranging, rare communities and coarse-filter targets (ecological systems and ecosystems) as well as other types of targets as appropriate. See the Ecoregional Assessment Data Standards 1.0 for required fields. Maps of occurrences of targets throughout the ecoregion. Description of data gaps for specific target groups and geographic areas. GUIDANCE A systematic approach to conservation planning demands that we be explicit about what features of biodiversity we are trying to conserve (Groves 2003). With the goal of conserving the biodiversity of an ecoregion, we need to define a subset of features to work with that will adequately capture that representation and variety. We refer to these features as conservation targets (Redford et al. 2003). Conservation targets are the species, communities, ecological systems 1 and surrogates that we focus our assessments on in order to capture the broad range of biodiversity as best we can.

The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage.

  • Benthic Macrofaunal Structure and Secondary Production in Tropical Estuaries on the Eastern Marine Ecoregion of Brazil
    Benthic macrofaunal structure and secondary production in tropical estuaries on the Eastern Marine Ecoregion of Brazil Lorena B. Bissoli and Angelo F. Bernardino Grupo de Ecologia Bêntica, Department of Oceanography, Universidade Federal do Espírito Santo, Vitoria, ES, Brazil ABSTRACT Tropical estuaries are highly productive and support diverse benthic assemblages within mangroves and tidal flats habitats. Determining differences and similarities of benthic assemblages within estuarine habitats and between regional ecosystems may provide scientific support for management of those ecosystems. Here we studied three tropical estuaries in the Eastern Marine Ecoregion of Brazil to assess the spatial variability of benthic assemblages from vegetated (mangroves) and unvegetated (tidal flats) habitats. A nested sampling design was used to determine spatial scales of variability in benthic macrofaunal density, biomass and secondary production. Habitat differences in benthic assemblage composition were evident, with mangrove forests being dominated by annelids (Oligochaeta and Capitellidae) whereas peracarid crustaceans were also abundant on tidal flats. Macrofaunal biomass, density and secondary production also differed between habitats and among estuaries. Those differences were related both to the composition of benthic assemblages and to random spatial variability, underscoring the importance of hierarchical sampling in estuarine ecological studies. Given variable levels of human impacts and predicted climate change effects on tropical estuarine

A NEW SPECIES OF CAVE ADAPTED NICOLETIID (ZYGENTOMA: INSECTA) FROM SISTEMA HUAUTLA, OAXACA, MEXICO: THE TENTH DEEPEST CAVE IN THE WORLD LUIS ESPINASA AND NGUYET H. VUONG School of Science, Marist College, 3399 North Road, Poughkeepsie, NY 12601, [email protected] and [email protected] Abstract: Anelpistina specusprofundi, n. sp., is described and separated from other species of the subfamily Cubacubaninae (Nicoletiidae: Zygentoma: Insecta). The specimens were collected in SoÂtano de San AgustõÂn and in Nita Ka (Huautla system) in Oaxaca, MeÂxico. This cave system is currently the tenth deepest in the world. It is likely that A.specusprofundi is the sister species of A.asymmetrica from nearby caves in Sierra Negra, Puebla. The new species of nicoletiid described here may be the key link that allows for a deep underground food chain with specialized, troglobitic, and comparatively large predators suchas thetarantula spider Schizopelma grieta and the 70 mm long scorpion Alacran tartarus that inhabit the bottom of Huautla system.

  • Forests Warranting Further Consideration As Potential World
    Forest Protected Areas Warranting Further Consideration as Potential WH Forest Sites: Summaries from Various and Thematic Regional Analyses (Compendium produced by Marc Patry, for the proceedings of the 2nd World Heritage Forest meeting, held at Nancy, France, March 11-13, 2005) Four separate initiatives have been carried out in the past 10 years in an effort to help guide the process of identifying and nominating new WH Forest sites. The first, carried out by Thorsell and Sigaty (1997), addresses forests worldwide, and was developed based on the authors’ shared knowledge of protected forests worldwide. The second focuses exclusively on tropical forests and was assembled by the participants at the 1998 WH Forest meeting in Berastagi, Indonesia (CIFOR, 1999). A third initiative consists of potential boreal forest sites developed by the participants to an expert meeting on boreal forests, held in St. Petersberg in 2003. Finally, a fourth, carried out jointly between UNEP and IUCN applied a more systematic approach (IUCN, 2004). Though aiming at narrowing the field of potential candidate sites, these initiatives do not automatically imply that all of the listed forest areas would meet the criteria for inscription on the WH List, and conversely, nor do they imply that any site left off the list would not meet these criteria. Since these lists were developed, several of the proposed sites have been inscribed on the WH List, while others have been the subject of nominations, but were not inscribed, for various reasons. The lists below are reproduced here in an effort to facilitate access to this information and to guide future nomination initiatives.

  • Resilience of Alternative States in Spatially Extended Ecosystems
    RESEARCH ARTICLE Resilience of Alternative States in Spatially Extended Ecosystems Ingrid A. van de Leemput*, Egbert H. van Nes, Marten Scheffer Department of Environmental Sciences, Wageningen University, Wageningen, The Netherlands * [email protected] Abstract Alternative stable states in ecology have been well studied in isolated, well-mixed systems. However, in reality, most ecosystems exist on spatially extended landscapes. Applying ex- isting theory from dynamic systems, we explore how such a spatial setting should be ex- pected to affect ecological resilience. We focus on the effect of local disturbances, defining resilience as the size of the area of a strong local disturbance needed to trigger a shift. We show that in contrast to well-mixed systems, resilience in a homogeneous spatial setting does not decrease gradually as a bifurcation point is approached.
