Primary production and biovolume of chroococcoid cyanobacteria in relation to other phytoplankton in southeastern US lakes

Description: Primary production rates and algal biovolumes were measured for various size classes of phytoplankton in three South Carolina lakes. Size classes of less than 3 ..mu..m accounted for 15 to 40% of the total primary production but only represented less than 5% of the total algal biovolume. Fluorescence microscopic analyses and laboratory culturing experiments indicated that chroococcoid cyanobacteria (unicellular blue-green algae) were primarily responsible for the relatively high primary product… more

Ecological distribution of Legionella pneumophila

Description: Bacteria were concentrated 500-fold from 20-liter water samples collected from 67 different lakes and rivers in the United States. The data suggest that Legionella pneumophila is part of the natural aquatic environment, and that the bacterium is capable of surviving extreme ranges of environmental conditions. The data further demonstrate the effectiveness of the direct fluorescent antibody technique for detecting L. pneumophila in natural aquatic systems. Smears of the concentrated samples were… more

Temporary Restoration of Bull Trout Passage at Albeni Falls Dam

Description: This study was designed to monitor movements of bull trout that were provided passage above Albeni Falls Dam, Pend Oreille River. Electrofishing and angling were used to collect bull trout below the dam. Tissue samples were collected from each bull trout and sent to the U. S. Fish and Wildlife Service Abernathy Fish Technology Center Conservation Genetics Lab, Washington. The DNA extracted from tissue samples were compared to a catalog of bull trout population DNA from the Priest River drainage… more

Fisheries Habitat Evaluation on Tributaries of the Coeur d`Alene Indian Reservation : Annual Report [1991].

Description: The purpose of this study was to conduct physical and biological surveys of streams located on the Coeur d'Alene Indian Reservation. Surveys were designed to collect information on improving spawning habitat, rearing habitat, and access to spawning tributaries for bull trout and cutthroat trout and to evaluate the existing fish stocks. The objectives of the second year of the study were to: (1) Develop a stream ranking system to select the five streams of primary fisheries potential; (2) Conduc… more

Instructional Models for Course-Based Research Experience (CRE) Teaching

Description: This article presents a study that was done over a period of 3 years to explicate the instructional processes involved in teaching an undergraduate course-based research experience (CRE). The study presented here delineated a set of specific instructional practices used by active CRE instructors and modeled the relations between the use of these practices and specified outcomes. The resultant educational models should provide clarification of the ways in which the aims of CRE can be effectively… more

The Effect of Carbon Monoxide on the Growth of an Aquatic Streptomycete

Description: The major purpose of this investigation was to determine the effect of carbon monoxide on the development of various morphological phases of a single isolate of the aquatic streptomycetes and to elucidate the physiological differences between terminal respiration in the primary and secondary stages. A secondary purpose was to repeat the work of Michael Lee Higgins involving the effect of anaerobiosis on the growth of the organism.
