New Bidirectional Ammonia Flux Model in an Air Quality Model Coupled With an Agricultural Model (JOURNAL)
Ammonia surface flux is often bidirectional, i.e., net flux can be either upward or downward. In fertilized agricultural croplands and grasslands there is usually more emission than deposition especially in mid-day during warmer seasons. In North America, most of the ammonia emi...
Influence of multi-decadal land use, irrigation practices and climate on riparian corridors across the Upper Missouri River headwaters basin, Montana (JOURNAL)
The Upper Missouri River headwaters (UMH) basin (36 400 km2) depends on its river corridors to support irrigated agriculture and world-class trout fisheries. We evaluated trends (1984–2016) in riparian wetness, an indicator of the riparian condition, in peak i...
Integrating LiDAR data and multi-temporal aerial imagery to map wetland inundation dynamics using Google Earth Engine (JOURNAL)
The Prairie Pothole Region of North America is characterized by millions of depressional wetlands, which provide critical habitats for globally significant populations of migratory waterfowl and other wildlife species. Due to their relatively small size and shallow depth, these w...
Managing Local Stressors for Coral Reef Condition and Ecosystem Services Delivery Under Climate Scenarios (JOURNAL)
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...
Short-term effect of simulated salt marsh restoration by sand-amendment on sediment bacterial communities (JOURNAL)
Coastal climate adaptation strategies are needed to build salt marsh resiliency and maintain critical ecosystem services in response to impacts caused by climate change. Although resident microbial communities perform crucial biogeochemical cycles for salt marsh functioning, thei...
A Needs-Driven, Multi-Objective Approach to Allocate Urban Ecosystem Services from 10,000 Trees (JOURNAL)
Urban areas face challenges including vehicular emissions, stormwater runoff, and sedentary lifestyles. Communities recognize the value of trees in mitigating these challenges by absorbing pollution and enhancing walkability. However, siting trees to optimize multiple benefits ...
Circuit theory applications to connectivity science and conservation (JOURNAL)
Conservation practitioners have long recognized ecological connectivity as a global priority for preserving biodiversity and ecosystem function. In the early years of conservation biology, ecologists extended principles of island biogeography to assess connectivity using measures...
How the distribution of anthropogenic nitrogen has changed in Narragansett Bay (RI, USA) following major reductions in nutrient loads. (JOURNAL)
Over the past decade, nitrogen (N) loads to Narragansett Bay have decreased by more than 50%. These reductions were, in large part, the direct result of multiple wastewater treatment facility upgrades to tertiary treatment, a process which employs N removal. Here, we document eco...
Penumbra: A spatially distributed, mechanistic model for simulating ground-level incident solar energy across heterogeneous landscapes (JOURNAL)
Landscape solar energy is a significant environmental driver, yet it remains complicated to model well. Several solar radiation models simplify the complexity of light by estimating it at discrete point locations or by averaging values over larger areas. These modeling approaches...
Realizing the Opportunities of Black carbon in Urban Soils: Implications for Water Quality Management with Green Infrastructure (JOURNAL)
Soil ecosystem processes regulate the carbon cycle, and provide a sink for atmospheric black carbon (BC). Particularly in urban soil, BC may act as an effective sorbent of contaminants in green spaces. We determined soil hydrology, soil carbon pools (organic carbon, black carbon,...
Interactions of predominant insects and diseases with climate change in Douglas-fir forests of western Oregon and Washington, U.S.A. (JOURNAL)
