Coastal blue carbon ecosystems offer a variety of important ecosystem services, including exceptional rates of carbon sequestration and long-term carbon storage. Because these ecosystems disproportionately influence global carbon cycling, understanding their soil characteristics may help guide long-term climate change mitigation and adaptation strategies. Recently, Kauffman et al. (2020) observed the...
This dissertation addresses gaps of knowledge associated with how ecosystem carbon stocks and greenhouse gas emissions are affected by land use land cover change in tropical peatlands. This was the first study that paired peat swamp forests with oil palm plantations and analyzed site scale variation on greenhouse gas emissions....
Mangroves provide numerous ecosystem services, including biodiversity values such as nesting sites for piscivorous waterbirds. High concentrations of pisicivoirous birds are hypothesized to affect ecosystem dynamics, yet few studies have examined their effects in mangroves. We examined the effects of nutrient enrichment by colonial waterbirds at a mangrove rookery in...
Hart Mountain National Antelope Refuge (HMNAR) established in 1936, is 101,000 ha in area. The refuge was grazed by domestic livestock from the 1870s until their exclusion in 1990. Just prior to removal of livestock, photopoints were taken at various riparian and wetland locations throughout the refuge to document riparian...
Riparian communities dominated by members of the
Salicaceae (Salix lasiandra, S. lutea, S. lemmonii,
Populus trichocarpa, P. tremuloides and S. exiqua) were
studied at the Crooked River National Grassland in central
Oregon. The objectives of this study were to examine the
relationships between the Salix and Populus species and
microsite...
Two studies on Catherine Creek and Meadow Creek of the Upper Grande Ronde
River basin, quantified several physical and biotic influences on woody riparian community
composition and structure. The Catherine Creek study examined the association of woody
riparian species with elevational and geomorphic gradients. The Meadow Creek study
examined the...
