Atlantic Surfclam (Spisula Solidissima) Population Demographics And Distribution Along The Middle Atlantic Bight, Mauricio González Díaz Dec 2022

Atlantic Surfclam (Spisula Solidissima) Population Demographics And Distribution Along The Middle Atlantic Bight, Mauricio González Díaz

OES Theses and Dissertations

The Atlantic surfclam (Spisula solidissima) is a long-lived benthic biomass dominant organism that occurs on the Middle Atlantic Bight (MAB) continental shelf between 10 m and 50 m. Trends in Atlantic surfclam population specific growth and mortality rates were analyzed using four decades of age and length observations obtained from NOAA stock surveys from the 1980s to 2010s in six regions distributed along the MAB. Atlantic surfclam specific growth rates and asymptotic lengths were estimated from the age and length observations using the von Bertalanffy growth model. The analysis showed that the Atlantic surfclam median asymptotic length in …

OUR Journal: ODU Undergraduate Research Journal

Tropical coral reefs are one of the most impressive and diverse ecosystems on the face of the earth. Found in warm, tropical waters around the globe, these reefs are major supporters of the immense biodiversity of the area. The health of coral reefs is highly influential on the overall health of the entire ecosystem. In recent years, intensifying climate change has resulted in an accelerated rise in seawater temperatures and the frequency and severity of coral bleaching. Coral bleaching occurs in response to harsh environmental conditions that cause corals to enter a period of extreme stress. During this time, corals …
