Global amphibian declines have been attributed to numerous and often synergistic causes, such as invasive species, pathogens, and ultraviolet-B (UV-B) radiation. The effects of these stressors are context dependent and can vary with location, species, and populations. As sensitivity to UV-B has shown inconsistencies across amphibian taxa, it can be...
Forecasts of the impacts of climate change have traditionally focused on individual species and their phenotypes, phenology, or distribution. However, shifts in species distributions and the resulting reorganization of community composition represent an important violation to the assumption of species acting in isolation. Whereas species may respond individualistically to climate...
Movement in an important component of an animal’s life cycle when it relies on both aquatic and terrestrial habitats. When multiple species overlap in the use of these habitats, they rely on other methods to reduce competition for shared resources. This dataset measured the jumping performance and movement behavior of...
Investigation into how animals move within the landscape is important for both understanding of ecological processes and conservation management. Animal movement is important in shaping life history transitions, demographics, individual fitness, and species distributions. However, as landscapes become increasingly affected by human activities, movement becomes important as species navigate landscapes...
This study examines the impact on Pacific Northwest
seafood exporters of the European Union Directive on packaging
and packaging waste management.
The study of the official text of the proposed Directive
was the starting point of our analysis. This allowed us to
give a presentation of the EU Directive and...
Since its creation in 1948, the African Franc Zone
currency (the CFA franc) was pegged to the French franc at an
unchanged fifty to one parity. This study examines the trade
effect of this fixed exchange rate on the Franc Zone's member
countries. Cameroon cotton exports is considered on a...
This study examines the link between policy-induced
changes in the relative prices of Mexican and U.S. frozen
vegetables and their shares of the U.S. market. Several
scenarios were examined in order to assess the impacts on
quantities demanded of both U.S. and Mexican produced
frozen vegetables caused by changes in...
Climate change, wildfire, timber harvest, and land conversion alter the availability of downed wood in forests of the western United States. Numerous taxa rely on downed wood for temperature and humidity refugia, and downed wood may play a key role in enabling the persistence of climate-sensitive, low-vagility species like terrestrial...
During Early and Middle Devonian time, the main part of the Death Valley area was characterized by shallow marine shelf position. In the extreme western part, deposition took place in carbonate slope environments. Early and Middle Devonian eastern platform dolomites, represented by uppermost Hidden Valley Dolomite and lower Lost Burro...
