Ecosystem Services and Ecological Processes
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 |
Tropical forest restoration: Fast resilience of plant biomass contrasts with slow recovery of stable soil C stocksBackgroundThe 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. 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.

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.

Microhabitats reduce animal’s exposure to climate extremesBackgroundThe Scheffers et al. (2014) paper discusses the effect of microhabitats and their corresponding microclimates on ectotherm species in a warming macroclimate. Available with subscription or purchase |
Sprouting, succession and tree species diversity in a South African coastal dune forestBackgroundThis 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.

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.

Small-scale disturbance and regeneration dynamics in a neotropical mangrove forestBackgroundThis study focuses on regeneration dynamics of mangrove species in lightening-created gaps, in the Dominican Republic. Open access copy available |
Diversity enhances carbon storage in tropical forestsBackgroundTropical forests are extremely important due to the ability to sequester large amounts of carbon and provide habitat for high levels of biodiversity, particularly tree species. Still there is limited understanding of the relationship between biodiversity and carbon. This study seeks to study this relationship and examine the forest attributes and environmental drivers for ecosystem functioning. Open access copy available |
Bioremediation of a crude-oil polluted agricultural-soil at Port Harcourt, NigeriaBackgroundSince more than 98% of Nigeria’s current economic support is crude oil, and oil spills are in inevitable and frequent, six treatment sample-cell were tested on the soils of the Niger Delta of Nigeria for crude oil bioremediation. Oil spills cause nitrogen levels to decrease, while increasing carbon content. A decrease in nitrogen and the toxicity of crude oil reduces the growth of heterotrophic bacteria, which utilize petroleum carbon for cell synthesis. Available with subscription or purchase |
