TL;DR: Inclusion of soil animals will improve the predictive capabilities of region- or biome-scale decomposition models, soil animal influences on decomposition are important at the regional scale when attempting to predict global change scenarios, and the statistical relationship between decomposition rates and climate, at the global scale, is robust against changes in soil faunal abundance and diversity.

TL;DR: This article used a short-term litterbag experiment to quantify the effects of litter quality, placement and mesofaunal exclusion on decomposition in 23 tropical forests in 14 countries, in which two standard substrates (Raphia farinifera and Laurus nobilis ) were decomposed in fine-and coarse-mesh litterbags both above and below ground for approximately 1 year.
Journal ArticleDOI
Tropical forest litter decomposition under seasonal drought: nutrient release, fungi and bacteria
TL;DR: Irrigation was used to study the consequences of seasonal drought for nutrient release and bacterial and fungal numbers during dry season litter decomposition in tropical forest on Barro Colorado Island, Panama.
Journal ArticleDOI
Characterization of SomeBeauveria bassianaIsolates and Their Virulence toward the Coffee Berry BorerHypothenemus hampei
Amanda Varela,Esperanza Morales +1 more
TL;DR: Some morphological and physiological characteristics and electrophoretic esterase profiles of six isolates of Beauveria bassiana were evaluated and laboratory bioassays were performed to assess their virulence against the coffee berry borer Hypothenemus hampei.
Journal ArticleDOI
