Dietary mineral requirements of Penaeus vannamei : evaluation of the essentiality for thirteen minerals and the requirements for calcium, phosphorus, copper, iron, zinc, and selenium
(1990)
The dietary requirements for calcium, phosphorus, Ca:P ration, copper, iron, zinc and selenium as well as the effects of phytate on zinc bioavailability to juvenile P. vannamei were evaluated utilizing a casein/gelatin ...
Molecular systematics of the tree bats (genus L̲a̲s̲i̲u̲r̲u̲s̲)
(1992)
Phylogenetic relationships among some members of the bat genus Lasiurus were investigated using a restriction enzyme analysis of the ribosomal genes of the mitochondrial molecule. A new restriction site mapping strategy ...
Water-depth and salinity relationships to vegetation dynamics in a Texas coastal marsh : a simulation approach
(1994)
Distribution of coastal marsh plants has been attributed to varying water depths and salinities. Relationships of water depth and salinity to live, above-ground biomass dynamics of Spartina alterniflora (smooth cordgrass), ...
Cold tolerance and thermal acclimation of juvenile blue tilapia, Tilapia aurea
(1995)
Cold resistance of blue tilapia (Tilapia aurea) was measured as the first step in development of a simulation model to predict acclimation state and mortality of tilapia exposed to varying low temperature. The model is ...
Essential fatty acid requirements and related aspects of lipid metabolism in the red drum, S̲c̲i̲a̲e̲n̲o̲p̲s̲ o̲c̲e̲l̲l̲a̲t̲u̲s̲
(1992)
Lipid is a vital macronutrient that provides energy and fatty acids which mediate important biochemical processes. Lack of information on the specific essential fatty acid (EFA) requirements of red drum, as well as their ...
Movements, habitat use, and population dynamics of elk in Guadalupe Mountains National Park, Texas
(1993)
The elk (Cervus elaphus) population in and adjacent to Guadalupe Mountains National Park, Texas was studied to determine its current status and use of habitat, as well as to better understand factors in the population ...
The mechanics and scaling of intake rate in mammalian herbivores
(1993)
The rate at which a herbivore consumes food exerts an important influence on many aspects of its life, including its activity budget, diet and habitat choices, social organization, and predator avoidance. To obtain food, ...
Dietary manipulation of lipid deposition and cold tolerance in juvenile red drum, Sciaenops ocellatus
(1994)
Two concerns of aquaculturists who produce red drum, Sciaenops ocellatus, are excessive lipid deposition and the susceptibility of this species to cold kill in outdoor ponds during severe winters. Alteration of lipid ...
Grass carp feeding preference in relation to plant nutrient content
(1994)
The role of plant nutrients in determining feeding preference of triploid grass carp, Ctenopharyngodon idella Val. was investigated. Feeding preference of grass carp was evaluated in two feeding series for Cabomba caroliniana, ...
Dietary protein and energy requirements of Penaeus vannamei and the optimal protein to energy ratio
(1995)
The dietary protein requirement of penaeid shrimp has been investigated under different experimental conditions. The recommended protein levels reported for each species have not been based on energy density of the diet ...
