Projections of Atmospheric Nitrogen Deposition to the Chesapeake Bay Watershed
(JOURNAL) [Published : Dec 26, 2019]
Atmospheric deposition is among the largest pathways of nitrogen loading to the Chesapeake Bay Watershed (CBW). The interplay between future climate and emission changes in and around the CBW will shift the future nutrient deposition abundance and regime (e.g., oxidized vs. redu...
Land-Use/Land-Cover Change from Socio-Economic Drivers and Their Impact on Biodiversity in Nan Province, Thailand
(JOURNAL) [Published : Jan 26, 2019]
The rate of deforestation declined steadily in Thailand since the year 2000 due to economic transformation away from forestry. However, these changes did not occur in Nan Province located in northern Thailand. Deforestation is expected to continue due to high demand for forest pr...
Combining the effects of increased atmospheric carbon dioxide on protein, iron, and zinc availability and projected climate change on global diets: a modelling study
(JOURNAL) [Published : Jul 01, 2019]
Background Increasing atmospheric concentrations of carbon dioxide (CO2) affect global nutrition via effects on agricultural productivity and nutrient content of food crops. We combined these effects with economic projections to estimate net changes in nutrient availability betw...
Managing Local Stressors for Coral Reef Condition and Ecosystem Services Delivery Under Climate Scenarios
(JOURNAL) [Published : Nov 09, 2018]
Coral reefs provide numerous ecosystem goods and services, but are threatened by multiple environmental and anthropogenic stressors. To identify management scenarios that will reverse or mitigate ecosystem degradation, managers can benefit from tools that can quantify projected c...
