Barbara Martin
My career has focused on two main areas of research 1) effects of contaminants on the aquatic environment and 2) habitat requirements of endangered species. Currently I am part of a team focused on identifying the causes of the declining Lost River and shortnose sucker populations in Upper Klamath Lake. My research is primarily composed of laboratory trials and combines my two areas of expertise.
Research Interests:
My long term research interests include examining the effects of contaminants and toxicants on imperiled species. My current research is focused on conducting laboratory experiments on Lost River suckers to try and determine what is preventing juvenile suckers from reaching maturity. It was hypothesized that age-0 juvenile sucker mortality increased due to the ingestion of prey items that had high levels of microcystin. Using laboratory experiments, I have been looking into the effects of ingested microcystin on Lost River suckers. Future laboratory experiments will focus on potential nutritional shortcomings, environmental effects on growth and condition of suckers, and effects of environmental contaminant on suckers. These laboratory experiments are fueled by observations in the field and provide supporting evidence for field and mesocosm studies.
