The ecology of Lepidurus apus in northern Utah and some limnological requirements for hatching

Creator:: Braswell, Audrey Lee Jr
Abstract:: A survey of the major bodies of water, temporary and perennial, in the region of Northern Utah revealed a limited distribution of the Notostraca. Lepidurus (Linn.), the only representative found, was restricted to a single temporary shallow lake. Dry Lake, in the southern end of Cache County. Dry Lake occupies...

Physiological alterations following severe hypoxic stress in two species of fresh-water fish

Creator:: Heath, Alan G.
Abstract:: Bluegill sunfish, Lepomia macrochirus, and cutthroat trout, Salmo clarki, were exposed to a rapidly declining oxygen tension for a period of time sufficient to just cause loss of equilibrium in the fish. During recovery from the stress, measurements of oxygen uptake, blood lactic acid, blood glucose, liver glycogen, muscle glycogen,...

The life cycle of the trematode Telolecithus pugetensis Lloyd & Guberlet, 1932

Creator:: DeMartini, John David
Abstract:: The fish Cymatogaster aggregata, Embiotoca lateralis and Phanerodon furcatus served as definitive hosts for the trematode Telolecithus pugetensis Lloyd and Guberlet. Eggs that were collected from the terminal part of the uterus of mature worms were found to have undergone several cleavages, but complete development was observed only in some...

Thermal ecology of the garter snakes Thamnophis sirtalis concinnus (Hallowell) and Thamnophis ordinoides (Baird & Girard)

Creator:: Stewart, Glenn R.
Abstract:: In recent years, studies dealing with temperature regulation, temperature sensitivity, and physiological responses to temperature in lizards and other reptiles have increased tremendously. It is notable that snakes have been largely ignored in such studies. This no doubt is due to their less direct relationship to ancestral endotherms. However, problems...

Digenetic trematodes of Ascaphus truei in western Oregon

Creator:: Anderson, Glenn Arthur
Abstract:: The Tailed Frog Ascaphus truei, the only species in the family Ascaphidae found outside New Zealand, is a common inhabitant of the mountain streams of the Northwestern United States and British Columbia. The anatomical peculiarities of this primitive anuran have been investigated, but no literature is available on the digenetic...

Catabolic pathways of carbohydrate in the intermolt crayfish, Pasifastacus leniusculus

Creator:: Puyear, Robert Louis
Abstract:: The radiorespirometric method was used to study the catabolism of glucose in intermolt crayfish. Rapid and extensive conversion of C-3(4) of glucose to C¹⁴O₂ indicated that a significant portion of the administered glucose was routed into the glycolysis- Krebs cycle sequence. High yields of C-6 of glucose in the respiratory...

Description and life history of Cardicola alseae sp.n. (Trematoda : Sanguinicolidae)

Creator:: Meade, Thomas Gerald
Abstract:: Cardicola alseae is a blood dwelling trematode found in the fishes Salmo clarki henshawi and Salmo gairdneri gairdneri. Eggs which were ovoid in shape and non-operculate left the adult and passed to the gill capillaries of the secondary lamellae. The miracidium was ovoid, 0.070 mm. long by 0.052 mm. wide,...

An analysis of a population of snowshoe hares, Lepus americanus washingtonii Baird, in western Oregon

Creator:: Black, Hugh C., 1941-
Abstract:: The ecology of a population of snowshoe hares, Lepus americanus washingtonii, was studied in western Oregon from 1960 to 1962. Objectives were to obtain information to control hares, which frequently cause damage to coniferous reproduction in the region, and to compare the life history of this little-studied subspecies with others....

A progenetic trematode (lecithodendriidae) life cycle involving Rana aurora

Creator:: Martin, Gordon Wyatt
Abstract:: A fluke found in the intestine of the red-legged frog, Rana aurora Baird and Girard, was identified as Brachycoelium lynchi Ingles 1936. The life cycle of this fluke was studied and found to be of the lecithodendriid type rather than brachycoeliid. Instead of having one intermediate host, as is the...
