Artificial Reefs As Juvenile Fish Habitats In Marinas, Allison Patranella
Artificial Reefs As Juvenile Fish Habitats In Marinas, Allison Patranella
HCNSO Student Theses and Dissertations
Coastal infrastructure has replaced many vital fish nursery habitats with structures designed without fully mitigating for the loss of the natural ecosystems. This thesis details research focused on the use of small, inexpensive, artificial reef modules as replacement juvenile fish habitat within marinas. My research hypothesis was that the placement of small, structurally complex artificial reef modules would increase fish abundance and species richness relative to unmodified marina seawalls. Non-destructive visual surveys of fishes were completed monthly for 14 months for 12 artificial reef sites and 12 control (unmodified) sites within the Nova Southeastern University Guy Harvey Oceanographic Center (NSU-GHOC) …
Coral Genotype Influence On Growth And Stress Resistance In Acropora Cervicornis: Investigating Potential Energy Tradeoffs, Peter T. Grasso
Coral Genotype Influence On Growth And Stress Resistance In Acropora Cervicornis: Investigating Potential Energy Tradeoffs, Peter T. Grasso
HCNSO Student Theses and Dissertations
Over the last few decades coral reefs have faced unprecedented declines in health due to natural and anthropogenic sources. Until recently few studies have examined genotypic variation of growth and thermal stress resistance in Acropora cervicornis. This study aims to assess the potential for energy trade-offs between growth and thermal stress resistance by following 120 coral fragments from 12 genotypes of Acropora cervicornis over the course of 15 months to determine average growth rates for each genotype. Following the completion of the growth observation a bleaching event occurred in the lower Florida Keys providing the opportunity for examining thermal …
