Brainstem Auditory Evoked Potentials In Anuran Amphibians, Marc Brandon Carey May 1992

Brainstem Auditory Evoked Potentials In Anuran Amphibians, Marc Brandon Carey

Dissertations and Theses

In this study, I looked at the effects of sound level, temperature and dehydration/hypernatremia on the brainstem auditory evoked potential (BAEP) of four species of anuran amphibians (Rana pipiens, Rana catesbeiana, Bufo americanus and Bufo terrestris). The BAEP was used because it allowed me to monitor both the peripheral and central aspects of auditory nervous function simultaneously and over a long period of time.


Experimental Manipulations Of The Organic Chemistry Of Seawater: Implications For Studies Of Energy Budgets In Marine Invertebrate Larvae, William Jaeckle Jan 1992

Experimental Manipulations Of The Organic Chemistry Of Seawater: Implications For Studies Of Energy Budgets In Marine Invertebrate Larvae, William Jaeckle

Scholarship

Correct measurement of changes in biomass and metabolic rates over time are two essential elements for the accurate construction of energy budgets for invertebrate larvae. Both components of larval energetics are altered by changes in the organic chemistry of the seawater. Axenic (bacteria-free) veliger larvae (88 µm shell length) of the bivalve Crassostrea gigas (Thunberg, 1795) had a 53% enhancement of their metabolic rate relative to control values (5.8 ± 0.6 pmol larva -1 h -1 , x¯ ± 1 SE) when exposed to seawater to which 1 µM glucose had been added. Gastrulae increased their rate of respiration by …
