Land Cover Change in Colombia: Surprising Forest Recovery Trends between 2001 and 2010backgroundThis study mapped annual land-use and land-cover from 2001 to 2010 in Colombia using MODIS (250 m) products coupled with reference data from high spatial resolution imagery (QuickBird) in Google Earth. Research Goals & MethodsThe authors evaluated land cover change at four spatial scales: country, biome, ecoregion, and municipality. Open access copy available |
Variation in the Population Structure Between a Natural and a Human-Modified Forest for a Pioneer Tropical Tree Species not Restricted to Large GapsBackgroundThe study was conducted in a permanent plot in a primary forest at Caetetus Ecological Station (CES), and in an early successional forest adjacent to the state reserve at Torrão de Ouro Farm, state of São Paulo, Southeast Brazil. This forest originally covered nearly the entire plateau in the state of São Paulo, and it is currently the most threatened forest in the State due to past fragmentation. Open access copy available |

Sixty-Seven Years of Land-Use Change in Southern Costa RicaBackgroundHabitat loss and fragmentation of forests are among the biggest threats to biodiversity and associated ecosystem services in tropical landscapes. This paper uses the vicinity of the Las Cruces Biological Station in southern Costa Rica as a regional case study to comment on seven decades of land-use change in one of the most intensively studied sites in the Neotropics.

Changes in vegetation structure and composition along a tropical forest chronosequence: implications for wildlifeBackgroundChanges in tropical forest structure and species composition that occur during regeneration following land abandonment may have important consequences for wildlife populations. Many animals rely on forest resources as sites for foraging, nesting, and protection that may vary in abundance in forests of different ages. This study examines aspects of forest composition and structure thought to be important to wildlife along a tropical moist forest chronosequence in the Barro Colorado Nature Monument of central Panama.

Functional Diversity Changes during Tropical Forest SuccessionbackgroundThis paper evaluates changes in species richness and functional diversity during tropical secondary forest succession following shifting cultivation in Chiapas, Mexico. It examines whether speces richness is a good predictor of functional diversity. Research Goals & MethodsFunctional diversity was calculated based on a combination of nine functional traits and two individual traits important for primary production: specific leaf area and carbon sequestration (wood density).

Identifying Hotspots of Deforestation and Reforestation in Colombia (2001–2010): Implications for Protected AreasbackgroundThis article uses satellite imagery, MODIS MOD13Q1 Vegetation Indices 250 , the Virtual Interpretation of EarthWeb-Interface Tool (VIEW-IT) to conduct a land-use analysis of Colombia, mapping trends and "hotspot" areas of deforestation and of reforestation from 2001 to 2010. Research Goals & MethodsThe authors identify four hotspots of deforestation (clustered particularly in lowlands in the north of the country) and four of reforestation, mainly in the Andes highlands.

Habitat Distribution of Dipterocarp Species in the Leyte Cordillera: an Indicator for Species – Site Suitability in Local Reforestation ProgramsBackgroundThis article presents the results of a vegetation study in primary forest areas of Leyte, in vicinity of the case study site (near Mt. Pangasugan). It provides information on habitat distribution patterns and elevational ranges of dipterocarp species with the purpose of providing baseline data for ensuring species-site suitability for local reforestation programs.

The Savannization of Moist Forests in the Sierra Nevada de Santa Marta, ColombiaBackgroundThis study in the Sierra Nevada de Santa Marta seeks to determine if savannas are natural or caused by anthropogenic factors. The authors use climate data from the past and present, the location of vegetation, and land use history to test their hypothesis. Available with subscription or purchase |
Methodology for Comparative Analysis of Sustainability in Agroforestry SystemsbackgroundThis paper analyses different forms of agroforestry systems, including political and institutional linkages in the Caí and Taquari river valleys of the Brazilian state of Rio Grande do Sul in an effort to determine their sustainability.
