Little research has focused on the economic impact associated with climate-change induced wildland fire natural ecosystems and goods services they provide. We examine changes in patterns based U.S. Forest Service's MC1 dynamic global vegetation model from 2013 to 2115 under two pre-defined scenarios: a reference (i.e., business-as-usual) greenhouse gas mitigation policy scenario. construct habitat equivalency which fuels management activities, actions commonly undertaken reduce frequency...
Abstract The size of the terrestrial carbon (C) sink is mediated by availability nutrients that limit plant growth. However, nutrient controls on primary productivity are poorly understood in geographically extensive yet understudied tropical dry forest biome. To examine how influence above‐ and belowground biomass production a secondary, seasonally forest, we conducted replicated, fully factorial nitrogen (N) phosphorus (P) fertilization experiment at stand scale Guanacaste, Costa Rica....
Climate change is altering wildfire activity across Alaska, with increased area burned projected for the future. Changes in are expected to affect need management and suppression resources; however, potential economic implications of these needs have not been evaluated. We associated response costs 2100 under relatively high low climate forcing scenarios (representative concentration pathways (RCP) 8.5 4.5) using Alaskan Frame-based Ecosystem Code (ALFRESCO) model. calculated unique each...
PREMISE OF THE STUDY: Tropical Montane Cloud Forests (TMCFs) are important ecosystems to study and preserve because of their high biodiversity critical roles in local regional ecosystem processes. TMCFs may be particularly affected by changes climate the narrow bands microclimate they occupy vulnerability TMCF species projected increases cloud base heights drought. A comprehensive understanding structure function is lacking difficult attain variation topography within across sites. This...
Canopy soils can be important to forest nutrient cycling, hydrology, and biodiversity, but the factors determining their distribution properties are largely unknown. We surveyed canopy across gradients of temperature precipitation in six primary forests Costa Rica. used solid-state 13C nuclear magnetic resonance (NMR) mass spectrometry (MS) understand how composition soil organic matter varies within sites. Climate, particularly fog, appears drive abundance forests, while tree size...
Abstract Tropical montane cloud forests support abundant epiphytic vascular plant communities that serve important ecosystem functions, but their reliance on atmospheric inputs of water may make them susceptible to the drying effects rising bases and more frequent droughts. We conducted a common garden experiment explore combined decreasing influence—lower humidity, warmer temperature, brighter light—and meteorological drought (i.e. absence rain) physiology morphology epiphytes native...
Abstract Soil organic carbon (SOC) sequestration is increasingly emphasized as a climate mitigation solution, scientists, policy makers, and land managers prioritize enhancing belowground C storage. To identify key underlying drivers of total SOC distributions, we compiled global dataset soil stocks held in three chemical forms, reflecting different mechanisms protection: free particulate (fPOC), physically protected (oPOC), mineral‐protected (mSOC). In our dataset, these pools were...

Abstract Epiphyte communities comprise important components of many forest ecosystems in terms biomass and diversity, but little is known regarding trade-offs that underlie diversity structure these or the impact microclimate has on epiphyte trait allocation. We measured 22 functional traits vascular across six sites span a microclimatic gradient tropical montane cloud region Costa Rica. quantified relate to carbon nitrogen allocation, gas exchange, water storage, drought tolerance....
