Genetic Consequences of Tropical Second-Growth Forest RegenerationBackgroundThis article is an examination of the genetic impacts of old-growth deforestation among 24 year-old second-growth Iriartea deltoidea, a canopy palm, in a lowland Costa Rican forest. Iriartea is widely distributed throughout neotropical rainforests and displays a diverse range of size classes in mature forests. This species recolonizes second-growth forests with newly generated seeds, which are dispersed by birds and mammals. Open access copy available |
Preliminary Studies on Imbrasia oyemensis, A valuable Non-Wood Forest Product in CameroonBackgroundIn many countries throughout Africa, Asia, and Latin America, insects significantly contribute to food security. One widely eaten insect in Cameroon is the Imbrasia oyemensis, an edible caterpillar. The caterpillar primarily feeds on the locally known Sapele tree, which is also exploited for timbr production. In order to understand more about the potential competitive nature between logginf and harvesting I. oyemensis, this study aims to examine some of the unknown factors of the moth species that contribute to its survival.

Assessing Forest Degradation: Towards the Development of Globally Applicable GuidelinesbackgroundThis FAO report defines forest degradation and provides guidelines for assessing levels of degradation with the purpose of influencing policies and forest management plans towards restoration. The report provides directions on how to measure four markers: 1) growing stock and biomass, 2) biodiversity, 3) production of forest goods, and 4) soil erosion. Open access copy available |
Les facteurs déterminants le succès de reproduction de la Tourterelle des bois (Streptopelia turtur) dans un milieu agricole Nord-AfricainThe authors provide ecological information regarding the use of trees and agriculture by the turtle dove. They argue for increased research to determine the success of fruit trees on sustaining populations of wildlife.

Dipterocarp Forest Ecosystems: Towards Sustainable ManagementBackgroundThis book describes the difficult problem of sustainably managing the valuable resources of Dipterocarp forests in Southeast Asia. It highlights the social, economic, and forest management challenges associated with Dipterocarp governance and attempts to reconcile the often disparate roles of forest scientists and local community managers.

Non-timber Forest Product Harvest does not Affect the Genetic Diversity of a Tropical Tree Despite Negative Effects on Population FitnessbackgroundThe authors investigated a relationship between exploitation of economically important mahogany in Benin and the species genetic diversity. The study is base on the theory that disturbances in forest habitats can lead to a decrease in diversity due to population fragmentation and increased inbreeding. Open access copy available |
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.

Participatory Forest Monitoring: An Assessment of the Accuracy of Simple Cost–Effective MethodsbackgroundThis article examines the feasibility of implementing participatory forest monitoring to conserve biodiversity and improving livelihoods for local communities. Long-term monitoring of forest conservation sites by professional scientists, is often cost prohibitive and uses techniques irrelevent to local community members, while simpler methods could be learned and implemented by local communities and more affordable.

Coffee Agroforests Remain Beneficial for Neotropical Bird Community Conservation across SeasonsBackgroundThis study compares bird community composition in coffee agroforestry systems with secondary forest fragments, while accounting for seasonal bird migration and differences in bird detectability between habitats. It was conducted in the San Luis Valley of northwest Costa Rica, a montane forest region that encompasses many microhabitats. Open access copy available |
