Functional divesity changes during tropical forest succession

Background

This paper evaluates changes in species richness and functional diversity during tropical secondary forest succession following shifting cultivation in Chiapas, Mexico, particularly examining whether speces richness is a good predictor of functional diversity. Functional 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).

Anthropogenic disturbance in tropical forests can double biodiversity loss from deforestation

Background

The authors examined the impacts of anthropogenic disturbances within a forest on the ability of the forest to conserve biodiversity and provide ecosytem services. The research used large data sets of plants, birds, and dung beetles and used them as indicators of biodiversity change in the forest.

Policy Options for the World's Primary Forests in Multilateral Environmental Agreements

Background

Around the world, primary forest continue to decline. The authors of this article recognize that international forest policies is one means to slow or turn around these trends and thus they identify four new actions that can provide a policy foundation for key international negotiations.

Floristic composition, structure and natural regeneration in a moist semideciduous forest following anthropogenic disturbances and plant invasion

Background

This research examined the floristic composition, struture and natural regeneration in three different forests: undisturbed (UF), disturbed-invaded (DIF) and disturbed (DF) within a forest reserve in Ghana.

Targeted habitat restoration can reduce extinction rates in fragmented forests

Background

Habitat lost is one of the primary drivers of species extinction. This study examines two highly-fractured ecosystems, the Eastern Arc Mountains of Tanzania and the Atlantic Forest of Brazil, and evaluates the rate at which habitat loss may lead to extinction and thus biodiversity loss. Specifically, the authors use halflife vs. area relationship to determine how long it will take to lose one-half of all tropical bird communities in each habitat.

Tropical forest restoration: Fast resilience of plant biomass contrasts with slow recovery of stable soil C stocks

Background

The study looks at three land-use types: 1) land left barren after a clear-cut in the 1950s, with only a sparse cover of shrubs, grasses, and vines, 2) a Eucalyptus exserta plantation established in the 1960s, and 3) a eucalyptus plantation that was clear-cut in 1974 and converted into a plantation of native tree species, now considered a secondary forest. The biomass and soil carbon (C) of these three land-use types were compared to a nearby natural old-growth forest.

Tropical Montane Forest Restoration in Costa Rica: Overcoming Bariers to Dispersal and Establishment

Background

The article addressed different types of environmental and ecological factors limiting forest regeneration on a tropical montane abandoned pasture in Costa Rica, and the subsequent forest restoration strategies that could be feasible.  The authors sought to answer the following questions: 1) What factors limit tropical forest recovery in abandoned pasture? and (2) How can we use this information to design strategies to facilitate ecosystem recovery?

Industrial Resource Extraction and Infrastructure Development in Tropical Forests

Background

This publication summarizes the proceedings of a 2012 conference held in Panama City, Panama titled "Industrial Resource Extraction and Infrastructure Development in Tropical Forests" The conference sought to explore how the continued increase in economic interest in natural resource extraction can be beneficial connected to the protection of tropical forests. The conference gathered scientists, decision makers, academics, government officials, representatives from NGOs and the private sector, and community and indigenous leaders and involved opening and closing remarks along with four panels.

Sprouting, succession and tree species diversity in a South African coastal dune forest

Background

This study examines the role of sprouting in the maintenance of plant diversity where prevailing disturbance frequency and severity allows, specifically, in the coastal dune forest of Kwazulu-Natal.

Drug Policy as Conservation Policy: Narco-Deforestation

Background

Central America exploded into prominence as a drug trafficking corridor in the last decade. The authors documented that an unprecedented flow of cocaine into Central America “coincided with a period of extensive forest loss”. The authors discuss the evidence that supports the idea that "trafficking of drugs (principally cocaine) has become a crucial—and overlooked—accelerant of forest loss” in Central America.
