  2. 1. Origin, evolution and biodiversity of the Neotropical herpetofauna: patterns and processes of the world’s richest and most threatened biota

    Author : Josué Azevedo; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amazonia; biodiversity indices; Cerrado; integrative taxonomy; phylogenetic endemism; phylogenetic turnover;

    Abstract : The biological diversity of tropical America (the Neotropics) is astonishing. However, even among terrestrial vertebrates, most biogeographical patterns are not fully described nor understood, especially for many Neotropical reptiles and amphibians (the herpetofauna). READ MORE

  4. 2. Global Savannah Phenology : Integrating Earth Observation, Ecosystem Modeling, and PhenoCams

    Author : Niklas Boke-Olén; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Savannahs are land areas where grass and trees co-exists to create a landscape that is neither a grassland nor a forest. It is estimated that savannahs cover approximately one sixth of the global land surface. They also play an important role in the global carbon cycle due to their total size. READ MORE

    Abstract : Boreal forests and peatlands store over 30% of the global terrestrial carbon in their vegetation and soil. but changing climate can compromise the current carbon stock. READ MORE

  6. 4. Agricultural expansion impacts on wetland ecosystem services from Kilombero Valley, Tanzania

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecosystem services; land use change; management practices; fertilization; irrigation; water quality; and smallholder; Physical Geography; naturgeografi;

    Abstract : Land use change has major impact on the world’s wetland ecosystems and biodiversity. The motivation behind this change has been to increase agricultural production, often resulting in negative effects on water quality and soil fertility. READ MORE

  7. 5. Spatial problems in long-term forest planning : from preferences to plans

    Author : Anu Korosuo; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : In modern forest planning, it is important to account for the value of timber production and for other values of the forest. Important factors such as the protection of biodiversity, recreational use and traditional uses of forests are often connected to specific places in forests, or to the spatial structure of the forests.
