This presentation provides an overview of a presentation held during the Industry and Policy Day held at the IIFET 2016 Scotland conference in July 2016. The presentation was part of Session B3: Adapt, Improvise and Overcome - fishermen's responses to the LO. The session was chaired by Dr. Erik Lindebo...
Recent coastal disasters (e.g., Hurricane Sandy, Typhoon Haiyan) and chronic issues (e.g., Florida's "nuisance flooding") provide numerous examples of coastal communities struggling to adapt in the face of climate change impacts. Decision-makers and the public alike must reconcile the lack of "fit" between a rapidly changing environment and the effects...
The objectives of this thesis were to evaluate the responses of soil microbial communities to physical and chemical disturbances, and associate these responses with soil functional stability and changes in soil quality. The first study consisted of application of heat shocks (HS) to soils with contrasting land use history to...
The host fish for this study were collected from January
through June of 1965. Tidepools were selected at Bar View, Cape
Arago, Neptune State Park, Seal Rock, and Yaquina Head. Of the
187 fish examined, 132 were infected. The following host fishes
yielded the following parasites. New Host records are...
A series of experiments was designed to investigate differential
flood-tolerance and the phenomenon of flood-induced stomatal closure
of several fruit tree species. The first two experiments were conducted
with potted plants submerged outdoors 5-10 cm above the soil line.
Plant morphology, growth, leaf conductance (cL), and soil oxygen diffusion
rate...
Nitrification and denitrification are major biological processes transforming nitrogen (N) in soils to plant available N, highly leachable nitrate (NO₃⁻) and gaseous N oxides. Although many studies in the past have studied N cycling communities, the effect of increased N inputs on ammonia-oxidizer and denitrifier population dynamics is still under...
The optimum goal of forest management is to foster long-term productivity and ecological integrity while maintaining or increasing short-term growth and yield through sustainable practices. Understory vegetation plays a definite role in forest functions through nutrient cycling and habitat provisions. The objective of this study was to determine how salal,...
Ectomycorrhizal fungi (EmF) form symbioses with trees. These symbioses profoundly influence forest ecology. Certain EmF form specialized profusions of hyphae, known as ectomycorrhizal fungal mats (mats) which are visible to the naked eye, alter forest soil biogeochemistry, substantially contribute to soil microbial biomass/respiration and support unique microbial communities. Piloderma and...
The objective of this study was to examine the variation among ammonia-oxidizing and denitrifying communities in soils of a natural Fennoscandian boreal forest and of a forest with a long history of fertilization with different levels of nitrogen (N), and to examine whether there are any changes in the microbial...
