Deep Benthic Coral Habitats Of Glacier Bay National Park And Preserve, Alaska, Elise C. Hartill Aug 2019

Deep Benthic Coral Habitats Of Glacier Bay National Park And Preserve, Alaska, Elise C. Hartill

Electronic Theses and Dissertations

Glacier Bay National Park and Preserve in Southeast Alaska is a system of fjords that presents an ideal natural laboratory to study terrestrial, aquatic and marine patterns of succession due to its unique and recent history of deglaciation. The patterns of deep benthic community assemblages in the fjords of Glacier Bay were investigated by quantitative assessment of underwater photo-quadrats collected using a remotely operated vehicle. The percent cover and diversity of species were lowest near the glaciated heads of the fjords and highest in the Central Channel and at the mouths of the fjords of Glacier Bay, where oceanographic conditions ...


The Effect Of Embryonic Arsenic Exposure On The Sensorimotor Behavior Of Zebrafish (Danio Rerio), Laura Paye Apr 2019

The Effect Of Embryonic Arsenic Exposure On The Sensorimotor Behavior Of Zebrafish (Danio Rerio), Laura Paye

Honors College

The goal of this study is to determine the effect of arsenic exposure on vision in zebrafish (Danio rerio). The optic system of D. rerio is ideal for examining visual defects. Their eyes are similar to eyes of humans and can therefore be useful models in studies of human eye disease. Their optic system functions similarly to humans, so it is beneficial to observe how zebrafish are affected by contaminants in the environment. Arsenic is ubiquitous in groundwater, due to its natural presence in bed rock, but is elevated by human activities. In order to see any immediate effects on ...
