Tectonic erosion and consequent collapse of the Pacific margin of Costa Rica: Combined implications from ODP leg 170, seismic offshore data, and regional geology of the Nicoya Peninsula
P. Vannucchi, D.W. Scholl, M. Meschede, K. McDougall-Reid
2001, Tectonics (20) 649-668
The convergent margin off the Pacific coast of the Nicoya Peninsula of Costa Rica exhibits evidence for subduction erosion caused by the underthrusting Cocos plate. Critical evidence for efficacy of this process was recovered at the Ocean Drilling Program (ODP) drilling Site 1042 (Leg 170), positioned ???7 km landward of...

Haematological and physiological responses of brook charr, to untreated and limestone-neutralized acid mine drainage
M.B. Cole, D.E. Arnold, B.J. Watten, W. F. Krise
2001, Journal of Fish Biology (59) 79-91
Brook charr, Salvelinus fontinalis, exhibited depressed plasma sodium and elevated plasma glucose concentrations in untreated acid mine drainage effluent (AMD), at two dilutions. Plasma sodium and glucose concentrations remained stable in treated AMD, pulsed, fluidized beds of limestone and carbon-dioxide pre-treatment of influent, and in AMD-free water. Results indicate that effluents...

Prevalence of giant kidney worm (Dioctophyma renale) in wild mink (Mustela vison) in Minnesota
L. David Mech, Shawn P. Tracy
2001, American Midland Naturalist (145) 206-209
Of 138 wild mink (Mustela vison) from eastern Minnesota, 27% contained Dioctophyma renale, primarily in the right kidney. No significant difference between prevalence in adult male and immature male mink was found, nor between the prevalence in males versus female mink. Thirteen worms were found in one male mink, representing...
The influence of photoperiod and temperature on the Neosho Madtom (norturus placidus) reproductive cycle
J.L. Albers, M. L. Wildhaber, Douglas B. Noltie
2001, Report
The key to successful fish culture is to understand the environmental cues that trigger spawning. In temperate fishes, photoperiod and temperature are important in many species including the family Ictaluridae. The object of this study was to examine whether natural photo-thermal conditions in the laboratory could stimulate the reproductive cycle...

A water quality study was performed in the mainstem Klamath River from Keno, Oregon to Seiad Valley, California during 1996 through 1998. Four sites within the study area were continuously monitored using multiparameter recorders. Water quality sampling was also performed at these four locations in 1996 and 1997. Additional water...

An important component of ecological assessments is the ability to predict and display changes in ecosystem structure and function over a variety of spatial and temporal scales. These changes can occur over short (less than 1 year) or long time frames (over 100 years). Models may emphasize structural responses (changes...
