Polygyny in the bobolink : habitat quality and the adaptive complex

Creator:: Martin, Stephen George, 1941-
Abstract:: The adaptiveness of polygyny in passerines poses a particularly intriguing problem. The altricial young of this group require extended parental care, but young of polygynous pairings generally lack the undivided attention of the male which young of monogamous pairings receive. Polygynous offspring may thus be undernourished and experience greater mortality....

Cardiac and respiratory responses to hypoxia in the crab, Cancer magister (Dana)

Creator:: Stiffler, Daniel Francis
Abstract:: Heart rates and amplitudes were measured for both intact animals (in situ) and isolated hearts (in vitro) of the Dungeness crab, Cancer magister, exposed to low levels in oxygen. Recordings were also made of gill ventilation rate by measuring the frequency of scaphognathite (gill bailer) beats. Both the in vitro...

Osmotic and ionic regulation in the North American crayfish Pacifastacus leniusculus (dana)

Creator:: Kerley, David Emmet
Abstract:: Osmotic and ionic regulation was studied in the North American crayfish Pacifastacus leniusculus (Dana), stepwise acclimated to increasing salinities. Stepwise acclimation involved transferring crayfish at 48 hour intervals from freshwater to 100% seawater in 20% increments. In experiments where 70% seawater was used, animals were moved directly from 40 to...

Metabolic responses of the burrowing mud shrimp, Callianassa californiensis, to anoxic conditions

Creator:: Hawkins, Dan Lee
Abstract:: Callianassa californiensis (Dana), a burrowing crustacean inhabitant of estuarine mudflats along the Pacific coast, is subjected to severely hypoxic interstitial water twice each tidal cycle. A preliminary approach was made to understanding the metabolic mechanisms employed by Callianassa during periods of anoxic stress. Percent glycogen in the hepatopancreas and chela...
