Energetics and mechanics of swing phase during terrestrial locomotion

Creator:: Nelson, Frank E.
Abstract:: Previous attempts to understand the factors affecting the energetic cost of locomotion have found a direct link between the energetic cost and the mechanical work done during periods when the limb is in contact with the ground. However, when the limb is not in contact with the ground during the...

The effects of external salinity on carbon dioxide incorporation into free amino acids in Artemia nauplii

Creator:: Carpenter, John Frank
Abstract:: In Artemia salina nauplii acclimated in 0.25 M, 0.5 M, 1.0 M, 1.5 M, 2.0 M, and 2.5 M NaCl incorporation of ¹⁴CO₂ into free amino acids was greatly stimulated in the higher salinities. The ¹⁴C label was found in aspartic acid, serine, glutamic acid, proline and alanine. Hypersalinity also...

The role of perinatal androgens in the development of neuroendocrine and behavioral characteristics of the gray-tailed vole, Microtus canicaudus

Creator:: Spielvogel, Sandra Petersen
Abstract:: These studies examined the role of perinatal androgen in the development of neuroendocrine and behavioral characteristics of gray-tailed voles, Microtus canicaudus. When mature, females exhibited alternating vaginal smear patterns or persistent vaginal cornification; estrogen and progesterone concentrations were not correlated with vaginal smear patterns. Corpora lutea were not observed in...

Ecological physiology of the larvel brine fly Ephydra (Hydropyrus) hians, and alkaline-salt lake inhabiting Ephyrid (Diptera)

Creator:: Herbst, David B.
Abstract:: Dipterans of the family Ephydridae (shore and brine flies) are well known for their ability to tolerate and thrive in a wide variety of physically harsh circumstances. The immature stages of one such species of this family, Ephydra hians, are characteristically limited in distribution as benthic inhabitants of highly alkaline...

The role of luteinizing hormone-releasing hormone in the neuroendocrine control of seasonal reproduction in male rough-skinned newts, Taricha granulosa

Creator:: Zoeller, Robert T.
Abstract:: One hypothesis proposed to explain how the endocrine system controls reproductive cycles in seasonally breeding animals is that the hypothalamus undergoes seasonal changes in sensitivity to negative feedback by gonadal steroids. The result is seasonal changes in the secretion of luteinizing hormone-releasing hormone (LHRH) and gonadotropin secretion. The present experiments...

Isolation and characterization of a larval crustacean salt gland from the brine shrimp Artemia salina

Creator:: Lowy, Robert Joel
Abstract:: A method for isolating the salt gland (SG) from the larval brine shrimp has been developed. This extra-renal organ is removed from 5-10% of Stage Inauplii by vortexing after incubating the animals at 37°C for 8 hours in a saline solution buffered with 100 mM sodium phosphate at pH 7.6....

Endocrine regulation of sperm release in an anuran amphibian

Creator:: Whittier, Joan Margaret
Abstract:: The endocrine mechanisms involved in the initiation of sperm release from the vertebrate testis have not been elucidated. A seasonally breeding anuran amphibian, Hyla regilla, was selected as a model for testing the hypothesis that steroid action is involved in gonadotropin-stimulated sperm release. Experiments were carried out in vivo and...

Neuroanatomical distribution of androgen and estrogen receptors in the brain of the roughskin newt, Taricha granulosa

Creator:: Davis, Glen Andrew
Abstract:: The gonadal steroids, testosterone and estradiol, are known to be important modulators of neuronal functions and behaviors in most vertebrate species. These steroid hormones also elicit changes in neuropeptide synthesis and secretion, alter specific neurohormone receptor levels, and alter neuronal morphology and electrophysiology. Many of the actions of androgens and...
