Assessing Morphological Deformities In Cetaceans: Definition Of Patterns And Quantification With A Case Study (Madeira Island, Ne Atlantic), Erich Dietterle Dec 2017

Assessing Morphological Deformities In Cetaceans: Definition Of Patterns And Quantification With A Case Study (Madeira Island, Ne Atlantic), Erich Dietterle

Masters Theses, 2010-2019

Documenting deformities in cetaceans can lead to understandings in the health of the populations, but also the state of ocean and human health in an area. Deformities like skin lesions can lead to information about local pollution levels or possible diseases, while physical impacts can give insight into vessel traffic or fishing gear entanglement information. Cetaceans encounter threats like vessel strikes and fishing gear entanglements worldwide, but less obvious activities like whale watching or pollution can also have impacts. Studies have been conducted worldwide and around the Madeira Archipelago to document deformities, but there are various descriptions for what is …


The Effect Of Calcium In Artificial Substrates For Oyster Restoration: Implications For The Mitigation Of Oyster Population Decline, Jessie Mandirola May 2017

The Effect Of Calcium In Artificial Substrates For Oyster Restoration: Implications For The Mitigation Of Oyster Population Decline, Jessie Mandirola

Masters Theses, 2010-2019

Oyster populations in the Chesapeake Bay have declined by 99% over the past 150 years due to overharvesting, disease, ocean acidification, and poor water quality. Restoration efforts are needed to reestablish native oyster populations. Current restoration efforts utilize natural oyster shells but these methods are expensive and unsustainable. Therefore, restoration is starting to use artificial substrates instead. Concrete has been successfully used in previous research; spat will attach and oysters will grow. However, there is a lack of knowledge about how the composition of concrete effects oyster larval recruitment. We tested concrete made with limestone sand (“special concrete”) to increase …
