Forest Dynamics
Consequences of broadscale timber plantations for biodiversity in cleared forest landscapes of tropical and subtropical AustraliaBackgroundIn Australia, as in many countries, there has been a shift in timber production from native forests to plantations. While plantations are primarily considered an efficient means of producing timber, there is increasing interest in their potential contribution to biodiversity conservation. This paper conducts a literature review of the impacts of plantations on biodiversity and assesses plantation scenarios proposed for cleared rainforest landscapes in tropical and subtropical Australia.

Ouragans et diversite biologique dans les forets tropicales. L’exemple de la Guadeloupe (Hurricanes and diversity in tropical forests: the example of Guadeloupe).The authors examined the relationship between hurricane disturbances and biodiversity and found that diversity of forests increased their resistance to hurricane disturbances. They concluded that recurrence of strong hurricanes could lead to extirpation of rare or vulnerable non-pioneer species.

Trends in forest condition, threats and conservation action as derived from participatory monitoring in coastal KenyaBackgroundThe coastal forests of Kenya are conservation priorities hosting high levels of biodiversity. Monitoring of biodiversity in these forests is therefore necessary to understand and reverse negative trends in good time. Available with subscription or purchase |
Establishment of Tree Seedlings in the Understory of Restoration Plantations: Natural Regeneration and Enrichment PlantingsBackgroundThis study investigates how seedling establishment is affected in the understory of restoration sites of different ages (10,22 and 55 year-old) within the Brazilian Atlantic Forest. It also assesses some of the environmental microsite conditions that influenced the stand dynamics process. 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.

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 |
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 |
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.

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.

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.
