We proposed to test the hypothesis that ecologically relevant concentrations of pesticide mixtures will increase susceptibility of metamorphic amphibians to a fungal pathogen known as Batrachochytrium dendrobatidis, or Bd. Bd has received considerable attention as one of the causes of declining amphibian populations. We hypothesized that exposure to the contaminants...

Surface water quality is a growing concern in the Willamette River Basin and elsewhere. The region's growing population is dependent on the availability of clean water for drinking water, irrigation, wastewater dilution, and wildlife habitat. Watershed management to produce economic goods and environmental services requires an understanding of basic hydrologic...
The imposing andesite stratovolcano is the characteristic expression of subduction zone magmatism, posing hazards to coastal populations and bearing insight into deep Earth processes. On a map of a typical volcanic arc, one can easily distinguish the approximately linear alignment and regular spacing of these major edifices that stand out...
This thesis focuses on the identification of ecohydrological processes in nested system of catchments in a tropical alpine (the wet Andean páramo) ecosystem. We accomplish this by conducting a water stable isotopic characterization of water sources, an evaluation of the mean transit time (MTT) of streams waters, and the investigation...
An experiment was conducted to determine the effect of dietary copper (Cu)
on Cu status and lipid metabolism in Holstein and Jersey cattle. Eight Jersey and8
Holstein cows in mid-lactation were blocked by days in milk (169 ± 37) and
assigned at random to one of two diets. Cows received...
Le Maroc compte quelques 1000 Km de rivières salmonicoles 60.000 ha de retenues de barrages, 80 lacs colinéaires et d'importantes pêcheries d'anguille, de civelle, de palourde et de crevette. Hormis les eaux à aloses qui ont été gravement affectées par différentes formes de dégradation (déforestation, surpâturage, pollution, érosion etc...) et...
