Responses of aquatic and streamside amphibians to timber harvest: a review Responses of aquatic and streamside amphibians to timber harvest: a review
Stream-dwelling amphibians, which can be the dominant vertebrates of small streams in forests of the Pacific Northwest, are prototypic riparian or ganisms. Larvae of several species are totally aquatic, while adults use the terrestrial streamside (riparian) habitat to varying degrees. Impacts of timber harvest vary among species, physical habitats, and regions of the Pacific Northwest

Mineral resources of the U.S. Atlantic continental margin Mineral resources of the U.S. Atlantic continental margin
Most geologic materials may be usable resources in some form and at some time, whether it be for general land fill and aggregate, beach replenishment, construction material, or as a source of metals and fuels. Thus, most natural materials occurring within the Atlantic continental margin are resources, defined as “materials, including those only surmised to exist, that have present or...

Use of "specific" inhibitors in biogeochemistry and microbial ecology Use of "specific" inhibitors in biogeochemistry and microbial ecology
The above statement, although meant to be tongue in cheek, contains an essential truism: all work with inhibitors is inherently suspect. This fact has been known by biochemists for some time. However, use of chemical inhibitors of enzymic systems and membranes continues to be a common approach taken toward unraveling the biochemistry and biophysics of plants, animals, and microorganisms...

A history of human impacts on the Lake Erie fish community A history of human impacts on the Lake Erie fish community
The fisheries scientist working in the island region of Lake Erie has access to an extremely large and diverse freshwater fish community. It is the intention of this essay to discuss briefly that community and the impacts of human activities to provide future students and researchers with both current and historical information. Human settlements and development within the basin are...

An identifiable model for informative censoring An identifiable model for informative censoring
The usual model for censored survival analysis requires the assumption that censoring of observations arises only due to causes unrelated to the lifetime under consideration. It is easy to envision situations in which this assumption is unwarranted, and in which use of the Kaplan-Meier estimator and associated techniques will lead to unreliable analyses.
