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. Various t

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 discussed, fol

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.

Atlas de aves: Un metodo para documentar distribucion y seguir poblaciones
Los Atlas de Aves son proyectos nacionales o regionalies para trazar en mapas la distribucion en reproduccion de cada especie de ave. Ese procedimiento se esta usando en Europa, Australia, Nueva Zelanda, Norteamerica, y partes de Africa. El tama?o de los cuadrados varia de medio grado de latitud y Iongitud hasta 5 x 5 km. El trabajo de campo de cada proyecto exige aproxlmadamente cinco a?os, pero
