The loss of oyster reefs is attributed to a variety of causes including over fishing, disease, and periodic hypoxia. Hypoxia, as well as brief periods of anoxia, is a problem in Mobile Bay, in particular. Development of ...
Disruption of Embryonic Development in Channel Catfish, Ictalurus Punctatus, Using 'Sterile-Feral' Gene Constructs
(2005-08-15)
Channel catfish, Ictalurus punctatus, embryos were electroporated with a sterile feral 3 (SF3), sterile feral 4 (SF4), glutamate decarboxylase (GAD) or CAB constructs and a blank control. Doxycycline was applied to some ...
The Ants (Hymenoptera: Formicidae) of Alabama
(2005-08-15)
This thesis presents the first statewide survey of the ant fauna of Alabama in over seventy years. Since the first state survey by L.C. Murphree (in the 1930’s) to present, 154 species have been reported. Fifty-nine of the ...
Effects of Toxicants, Temperature, and Resistance on Metabolism and Gas Exchange Patterns of the Beet Armyworm, Spodoptera exigua (Hübner), and the German Cockroach, Blattella germanica (Linnaeus)
