Bacteria and fungi drive decomposition, a fundamental process in the carbon cycle, yet importance of microbial community composition for decomposition remains elusive. Here, we used an 18-month reciprocal transplant experiment along climate gradient Southern California to disentangle effects versus environment on decomposition. Specifically, tested whether response change depends community. We inoculated decomposers from each site onto common, irradiated leaf litter within "microbial cages"...
Mountains have a long history in the study of diversity. Like macroscopic taxa, soil microbes are hypothesized to be strongly structured by montane gradients, and recently there has been important progress understanding how shaped these conditions. Here, we summarize this literature synthesize patterns microbial diversity on mountains. Unlike flora fauna that often display mid-elevation peak diversity, found decline (34% time) or no trend (33%) total with increasing elevation. Diversity...
Abstract Few studies have investigated how soil fungal communities respond to elevation, especially within TMCF (tropical montane cloud forests). We used an elevation gradient in a Costa Rica determine properties, processes, and community composition of fungi change response across seasons. As increased, temperature pH decreased, while moisture C:N ratios increased with elevation. Responses these properties varied seasonally. Fungal abundance during wet dry shifted lesser extent by season....
Abstract Tropical montane cloud forests contain a large abundance and diversity of canopy epiphytes, which depend on soil to retain water nutrients. We lack an in depth understanding how these soils contribute ecosystem processes sensitive they may be projected climate change. compared ground Monteverde, Costa Rica, determine two types differ their extracellular enzyme activity (EEA) fungal communities. Samples were also collected along elevation gradients reveal if differed EEA communities...
Bromelia pinguin (Bromeliaceae) is a terrestrial bromeliad commonly found under forest stands throughout the Neotropics that has been shown to have antifungal activity in vitro. We hypothesized this would also an effect on fungal populations nearby soil by decreasing fungaldiversity and negatively impacting C N cycle-related activities. A previous study lowland of Costa Rica showed beneath these bromeliads had decreased ITS DNA differences levels compared adjacent primary soils. In follow-up...
