Deadwood is a large global carbon store with its size partially determined by biotic decay. Microbial wood decay rates are known to respond changing temperature and precipitation. Termites also important decomposers in the tropics but less well studied. An understanding of their climate sensitivities needed estimate change effects on pools. Using data from 133 sites spanning six continents, we found that termite discovery consumption were highly sensitive (with increasing >6.8 times per 10°C...
The decomposition of plant residues is influenced by their chemical composition, the physical–chemical environment, and decomposer organisms. Most studies interested in latitudinal gradients have focused on substrate quality climate effects decomposition, excluded explicit recognition soil organisms involved process. To test whether fauna exhibit different under diverse climates or substrates, we quantified rates N fluxes control fauna-excluded treatments with litterbags containing...
Arctic landscapes have visually striking patterns of small polygons, circles, and hummocks. The linkages between the geophysical biological components these systems their responses to climate changes are not well understood. “Biocomplexity Patterned Ground Ecosystems” project examined patterned‐ground features (PGFs) in all five bioclimate subzones along an 1800‐km trans‐Arctic temperature gradient northern Alaska northwestern Canada. This paper provides overview transect illustrate trends...
Intense hurricanes disturb many tropical forests, but the key mechanisms driving post-hurricane forest changes are not fully understood. In Puerto Rico, we used a replicated factorial experiment to determine of change associated with canopy openness and organic matter (debris) addition. Cascading effects from accounted for most shifts in biota biotic processes, which included increased plant recruitment richness, as well decreased abundance diversity several animal groups. Canopy opening...
Abstract Tropical forests play a critical role in carbon and water cycles at global scale. Rapid climate change is anticipated tropical regions over the coming decades and, under warmer drier climate, are likely to be net sources of rather than sinks. However, our understanding forest response feedback very limited. Efforts model impacts on fluxes have not reached consensus. Here, we use Ecosystem Demography (ED2) predict Puerto Rican realistic scenarios. We parameterized ED2 with...
Abstract Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial functions and services. Little is known about their diversity distribution at large spatial scales, despite the availability considerable amounts local-scale data. Earthworm data, obtained from primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, properties. Datasets required, minimum, to include...
ABSTRACT Leaffall phenology is an important periodical event in forests, contributing to mobilization of organic matter from primary producers soil. For seasonal leaffall periodicity has been related rainfall regime and dry season length. In weakly where there no marked season, other climatic factors could trigger leaf shed. this study, we aimed determine if variables (wind speed, solar radiation, photosynthetic photon flux density [PPFD], day length, temperature, relative humidity) be...
Abstract Question : What are the composition, conservation status, and structural environmental characteristics of eight mature tropical forest plant communities that occur along an elevational gradient. Location Northeastern Puerto Rico. Methods We quantified species diversity, ecological attributes in replicated plots located to sample representative components important types occurring A suite vegetation were sampled at each plot summarized characterize analyse trends Results The set...
Abstract The response of tropical forests to global warming is one the largest uncertainties in predicting future carbon balance Earth. To determine likely effects elevated temperatures on forest understory plants and soils, as well other ecosystems, an infrared (IR) heater system was developed provide situ for Tropical Responses Altered Climate Experiment ( TRACE ) Luquillo Experimental Forest Puerto Rico. Three replicate heated 4‐m‐diameter plots were warmed maintain a 4°C increase...
Abstract: Tropical montane forests (TMF) are associated with a widely observed suite of characteristics encompassing forest structure, plant traits and biogeochemistry. With respect to nutrient relations, characterized by slow decomposition organic matter, high investment in below-ground biomass poor litter quality, relative tropical lowland forests. However, within TMF there is considerable variation substrate age, parent material, disturbance species composition. Here we emphasize that...
Abstract As is true of many tropical regions, northeastern Puerto Rico an ecologically sensitive area with biological life that highly elevation dependent on precipitation and temperature. Climate change has the potential to increase risk losing endemic species habitats. Consequently, it important explore pattern trends in temperature along gradient. Statistical derivatives a frequently sampled dataset at 20 sites gradient 1000 m were examined for from 2001 2013 nonparametric methods...
Litter decomposition is a key process for carbon and nutrient cycling in terrestrial ecosystems mainly controlled by environmental conditions, substrate quantity quality as well microbial community abundance composition. In particular, the effects of climate atmospheric nitrogen (N) deposition on litter its temporal dynamics are significant importance, since their might change over course process. Within TeaComposition initiative, we incubated Green Rooibos teas at 524 sites across nine...
