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...
Interactions between plants and herbivores are central in most ecosystems, but their strength is highly variable. The amount of variability within a system thought to influence aspects plant-herbivore biology, from ecological stability plant defense evolution. Our understanding what influences variability, however, limited by sparse data. We collected standardized surveys herbivory for 503 species at 790 sites across 116° latitude. With these data, we show that within-population increases...
Summary Tropical forest root characteristics and resource acquisition strategies are underrepresented in vegetation global models, hampering the prediction of forest–climate feedbacks for these carbon‐rich ecosystems. Lowland tropical forests often have globally unique combinations high taxonomic functional biodiversity, rainfall seasonality, strongly weathered infertile soils, giving rise to distinct patterns traits functions compared with higher latitude We provide a roadmap integrating...
Vegetation processes are fundamentally limited by nutrient and water availability, the uptake of which is mediated plant roots in terrestrial ecosystems. While tropical forests play a central role global water, carbon, cycling, we know very little about tradeoffs synergies root traits that respond to resource scarcity. Tropical trees face unique set limitations, with rock-derived nutrients moisture seasonality governing many ecosystem functions, versus availability often separated spatially...
Fine roots balance multiple essential plant functions that ultimately fuel productivity. The coordination of root functional traits is multidimensional, meaning some are correlated while others can vary independently. This leads to a large variety adaptive trait combinations and thus diversity in belowground morphology, anatomy, physiology symbioses with soil biota. Within forest communities, co‐occurrence such may be especially prevalent tropical forests, not only due their immense...
Drought can alter leaf senescence and nutrient resorption, but whether these alterations are consistent between trees of contrasting habits remains unclear. We conducted an experiment for 2 years with potted saplings to compare habit drought effects on abscission dynamics resorption proficiency in two evergreen deciduous Nothofagus (Nothofagaceae) species from southern temperate forests. A global meta-analyses has found similar nitrogen (N) habits, greater phosphorus (P) evergreens; however,...
Four different perspectives—from the director of a scholarship teaching and learning dialogue forum, leadership institute, two undergraduate students—join together to discuss collaboration in optimizing education at Western Washington University.
Abstract Animals, such as termites, have largely been overlooked global-scale drivers of biogeochemical cycles 1,2 , despite site-specific findings 3,4 . Deadwood turnover, an important component the carbon cycle, is driven by multiple decay agents. Studies focused on temperate systems 5,6 where microbes dominate 7 Microbial sensitive to temperature, typically doubling per 10°C increase (decay effective Q 10 = ~2) 8–10 Termites are decayers in tropical 3,11–13 and differ from their...
