Biotelemetry study of spring and summer habitat selection by striped bass in Cherokee Reservoir, Tennessee, 1978. [Morone saxatilis]

Description: Habitat selection of 31 adult striped bass was monitored by temperature sensing ultrasonic and radio transmitters in Cherokee Reservoir, Tennessee, from March through October 1978. This study sought to corroborate summer data obtained by Waddle (1979) in 1977 and to examine mechanisms of habitat selection by observing establishment of the summer distribution. During the spring and early summer months the striped bass ranged throughout the study area in the downstream half of the reservoir. Fish… more

Phenotypic and genotypic components of growth and reproduction in Typha latifolia: experimental studies in three contrasting marshes

Description: The magnitude and causes of intraspecific variation in biomass production and allocation, and morphology for Typha latifolia L. from three marshes which can be distinguished by their successional maturity were investigated. The first stage of investigation was to determine the environmental characteristics of the three marshes and the characteristics of the T. latifolia populations. Second, in situ studies of /sup 14/C fixation and allocation were used to determine the phenotypic variation in b… more

Summer habitat selection by striped bass, Morone Saxatilis, in Cherokee Reservoir, Tennessee, 1977

Description: Summer habitat selection patterns of 18 adult striped bass (Morone saxatilis) in Cherokee Reservoir were monitored with externally attached temperature-sensing acoustic or radio transmitters from June through September 1977. Mortalities of adult striped bass in this reservoir were hypothesized to be related to high summer temperatures and low dissolved oxygen (DO). The inhabited areas or refuges differed from noninhabited areas by maintaining temperatures less than or equal to 22 C and DO conce… more

Continuation of studies on thermoregulation of fish and turtles in thermally stressed habitats. Summary progress report, 1 October 1977-30 September 1980

Description: Biophysical-behavioral-ecological models have been completed to explain the behavioral thermoregulation of largemouth bass (Micropterus salmoides) and turtles (Chrysemys scripta). Steady state and time dependent mathematical models accurately predict the body temperatures of largemouth bass. Field experiments using multichannel radio transmitters have provided temperatures of several body compartments of free ranging bass in their natural habitat. Initial studies have been completed to describe… more

Behavioral ecology of the Swainson's Hawk (Buteo swainsoni) in Washington

Description: This study examines the breeding ecology and behavior of the Swainson's Hawk (Buteo swainsoni) on its breeding ground in southeastern Washington. Seasonal movements and distribution of the buteo are also described. The birds were observed from blinds, or filmed by Super-8mm time-lapse cameras, during courtship, nest building, egg laying, incubation, and nestling and post-fledging development. Food habits were examined during the nestling and post-fledging periods. Snakes, especially the abundan… more
