Use of large-scale, multi-species surveys to monitor gyrfalcon and ptarmigan populations Use of large-scale, multi-species surveys to monitor gyrfalcon and ptarmigan populations
We evaluated the ability of three large-scale, multi-species surveys in the Arctic to provide information on abundance and habitat relationships of Gyrfalcons (Falco rusticolus) and ptarmigan. The Program for Regional and International Shorebird Monitoring (PRISM) has surveyed birds widely across the arctic regions of Canada and Alaska since 2001. The Arctic Coastal Plain survey has...

An approach to modeling coupled thermal-hydraulic-chemical processes in geothermal systems An approach to modeling coupled thermal-hydraulic-chemical processes in geothermal systems
Interactions between hydrothermal fluids and rock alter mineralogy, leading to the formation of secondary minerals and potentially significant physical and chemical property changes. Reactive transport simulations are essential for evaluating the coupled processes controlling the geochemical, thermal and hydrological evolution of geothermal systems. The objective of this preliminary...

An analytical model to predict dune and cliff notching due to wave impact An analytical model to predict dune and cliff notching due to wave impact
A model was developed to calculate the evolution of a notch in a dune or cliff due to wave impact. Analytical solutions were derived to the model for schematized conditions regarding forcing and dune/cliff properties. Comparisons were made with laboratory experiments where the time evolution of the notch was measured. Values of the transport coefficients in the analytical solutions were...

Host specificity and ecology of infectious hematopoietic necrosis virus (IHNV) in Pacific salmonids Host specificity and ecology of infectious hematopoietic necrosis virus (IHNV) in Pacific salmonids
Some circumstances IHNV infection can cause acute disease with mortality ranging from 5-90% in host populations. Genetic typing of IHNV field isolates has shown that three major genetic groups of the virus occur in North America. These groups are designated the U, M, and L virus genogroups because they occur in the upper, middle, and lower portions of the geographic range of IHNV in...

I3N risk assessment and pathway analysis: Tools for the prevention of biological invasions I3N risk assessment and pathway analysis: Tools for the prevention of biological invasions
Information on invasive alien species from published and unpublished accounts and databases is usually scattered in locations and formats that are not easily accessible. Customized informatics tools for collecting and organizing invasive species information can help resource managers better control biological invasions. The Invasives Information Network (I3N) of the Inter-American...

Land cover change, biogeochemical modelling of carbon stocks, and climate change in West Africa Land cover change, biogeochemical modelling of carbon stocks, and climate change in West Africa
The carbon in ecosystems exists in dynamic soil and vegetation pools which vary in amounts and cycle with the global atmosphere at varying rates. These stocks and fluxes play important roles in global carbon regulation and in the maintenance of goods and services. Changes in land cover or ecosystems result in increased or decreased fluxes to the atmosphere and play a major role in...

Long-term natural attenuation of crude oil in the subsurface Long-term natural attenuation of crude oil in the subsurface
The time frame for natural attenuation of crude oil contamination in the subsurface has been studied for the last 27 years at a spill site located near Bemidji, Minnesota, USA. Data from the groundwater contaminant plume show that dissolved benzene concentrations adjacent to the oil decreased by 50% between 1993 and 2007. To assess how this decrease is related to benzene concentrations...
