Anthropogenic disturbance in tropical forests can double biodiversity loss from deforestationBackgroundThe 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. Open access copy available |
Targeted habitat restoration can reduce extinction rates in fragmented forestsBackgroundHabitat 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. Open access copy available |
Factors Affecting Mortality and Resistance to Damage Following Hurricanes in a Rehabilitated Subtropical Moist ForestBackgroundThis study was conducted in the Luquillo Experimental Forest (LEF), which was previously abandoned pastureland reforested through mixed planting and natural regeneration.

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

Screening of native plant species for phytoremediation potential at a Hg-contaminated mining siteBackgroundThis study was conducted in one of the most important Artisanal and small-scale (ASGM) gold-mining sites in Colombia, to identify native plant species growing in Mercury contaminated soils used for agricultural purposes, and to assess their potential as phytoremediation systems.

Industrial Resource Extraction and Infrastructure Development in Tropical ForestsBackgroundThis 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.

Drug Policy as Conservation Policy: Narco-DeforestationBackgroundCentral 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.

Asymmetric density dependence shapes species abundances in a tropical tree communityBackgroundThis study examined the question: why are some species common in tropical rainforests while others are rare? Goals & MethodsThe research, which used a computer modeling approach to analyze data from 20,000 1-meter squared plots, examined the degree to which being close to another individual of the same species affected the studied individual's overall abundance.

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 evaluates the distribution of Cyperus floribundus (a long-lived pioneer tree specie) individuals in the gaps and compared the plant density between a primary and an early successional forest to understand the pioneer plant distribution and niche preference under the variable environmental and biotic conditions generated by natural or anthropogenic disturbances.
