Master’s Thesis: Effects of diel-cycling hypoxia on the cardiac activity and growth of Argopecten irradians

Published in Stony Brook University, 2017

Coastal dynamic stressors demand a high-resolution proxy for performance. Here my thesis summarizes research from 2015-2017 on the cardiac activity and growth of adult Bay scallops under in-situ hypoxia and laboratory challenges (accompanied with metabolic rates and condition indices). I propose a model for the aerobic and anaerobic implications of cardiac response under diel-cycling hypoxia.

Cardiac responses of the bay scallop Argopecten irradians to diel-cycling hypoxia

Published in Journal of Experimental Marine Biology and Ecology, 2018

This paper is a ecophysiological study on cardiac and respiratory responses of the Atlantic bay scallop (Argopecten irraidians) under both in-situ diel-cycling cycling hypoxia and laboratory challenges. Findings conclude with a conceptual model on the oxyregulatory and oxyconformity response to diel-cycling hypoxia as a summation of in-situ cardiac response, decoupled metabolic/cardaic response to laboratory challenges, and biohemical implications from literature review

Application Note: Alternative image-based technique for phytoplankton cell counts in shellfish aquaculture

Published in Nexcelom LLC, 2018

Experiments in summer 2018 required daily algae counts to calculate a continuous and accurate diet for rearing juvenile geoduck (Panopea generosa). This app note was written for the Nexcelom Cellometer, an instrument that uses bright-field images to count cells - I used the Cellometer to count large algae batch cultures daily for a continuous mixed-algae diet. To the best of my knowledge, this was the first use of the Cellometer was in a sustainable shellfish hatchery.
