Forests, atmospheric water and an uncertain future: the new biology of the global water cycleIntroductionThis article provides a review of the connection between vegetation cover and climate, with a specifical focus on forests and rain. The author details how there are shortcomings in knowledge concerning how tree cover influences water-cycles, which are both highly complex and important. In order to direct readers to potential research opportunities in this field, the article highIights advances and uncertainties in this field through reviewing it's major research themes.

Insectos vs suelo: la importancia de elegir indicadores para el monitoreo de la restauración ecológica.EspañolAntecedentesAmenazados por la degradación de suelos y la sobreexplotación de recursos naturales, los bosques andinos han sido objetos de mutiples proyectos e iniciativas de restauración forestal. Para ser exitosos, los proyectos de restauración deben incluir un plan de monitoreo comprensivo que evalúe indicadores relevantes y sensibles a cambios en el ecosistema. La selección de estos indicadores de monitoreo debe ser juiciosa y hecha en función a los objetivos de la restauración. 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 |
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 |
Development of the soil macrofauna community under silvopastoral and agrosilvicultural systems in AmazoniaBackgroundThe Brazilian Amazon has experienced extensive land conversion from forests to cattle pasture, many of which now lay abandoned. Agro-forestry serves as one potential solution to this problem and this study examines the re-establishment of a diversified soil macrofauna in order to inform this approach.
