Ecosystem Services and Ecological Processes
Using Melaleuca Fences as Soft Coastal Engineering for Mangrove Restoration in Kien Giang, VietnamBackgroundThis study examines the installation of two fence designs made from Melaleuca poles along coastal fringe mangroves to attenuate wave action and promote accretion of sediments in Southwest coastal Vietnam.

Effects of Invasive Alien Plants on Fire RegimesBackgroundThis article considers how invasive plant species affect native ecosystems by altering fuel properties, fire behavior and fire regime characteristics. These may impact the ability of a site to restore to its previous state. Open access copy available |
Succession and Management of Tropical Dry Forests in the Americas: Review and New PerspectivesBackgroundThis article emphasizes the importance of understanding of successional processes in tropical dry forests. It provides an overview of the current knowledge of the ecology of tropical dry forest ecosystems and discusses management implications . The authors describe rapidly increasing degradation and destruction of these ecosystems and identify gaps in knowledge to be addressed by future research. Available with subscription or purchase |
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.

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.

The Role of Silvopastoral Systems in the Rehabilitation of Andean Stream HabitatsbackgroundThis article discusses the prevalence and impact of cattle grazing in the Andean region of Colombia. It asserts that ranching drastically alters the oxygen demand of and pH of streams, increases algae growth, and reduces light penetration. Ranching also damages stream flow and riverbanks, leading to higher erosion and run-off. Grasslands on previously forested areas have led to compaction of soil so that there is less infiltration leading to more run-off, floods due to increased speeds and volume, and less water in the streams during the dry season.

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 |
Neotropical Secondary Forest Succession: Changes in Structural and Functional CharacteristicsBackgroundThis paper reiviews the main biotic and abiotic factors that influence patterns of secondary forest succession in the Neotropics after complete forest clearance due to human activities. Research Goals & MethodsThe authors look at patterns of species replacement and various processes that occur during succession and suggest that the sequence of processes may be predictable even if species composition is not.

Seed Dispersal by Birds and Bats in Lowland Philippine Forest Successional AreaBackgroundWhile seed dispersal by birds and bats can be an important driver of succession, few studies have studied this dynamic in the tropical forests of SE Asia. This study compares the role of bird and bat dispersal in the lowland dipterocarp forest of the Subic Watershed Forest Reserve (SWFR) in Luzon Island, Philippines.
