Evaluating Extinction Risk in Major Marine Taxa

By Olivia Schuitema, SRC intern Over Earth’s history, there have been at least five mass extinctions in addition to other minor-scale extinctions (Bambach et al. 2004). The causes of such extinctions are varied, but many be associated with global climate variability (Doney et al. 2012). One article points to large-scale volcanism associated with global warming, […]

Noise Pollution in the Ocean: A Growing Problem

By Rachael Ragen, SRC intern Marine animals face many forms of pollution, but one of the less obvious forms that has potentially dangerous effects is noise pollution. Humans have always established civilizations near the water, but humans continue to explore further into the ocean and discover new resources. This shift brings a large amount of […]

Ingestion of Marine Debris and Sperm Whales

By Jessica Daley, SRC intern Marine debris is one of the greatest threats facing marine life today. Any man-made, produced, or processed material that is either intentionally or accidentally discarded and finds its way to the ocean is considered marine debris. There are two major hazards to marine life from interactions with debris, entanglement and […]

The Effect of Hurricane Hermine on Black Sea Bass

By Delaney Reynolds, SRC intern In September of 2016, Hurricane Hermine struck Florida as a category one hurricane and then migrated through Georgia, South Carolina, North Carolina, and then to offshore Maryland. According to the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI), Hermine’s damage “totaled around $550 million, with a […]

Combining hard-part and DNA analyses
of scats with biologging and stable isotopes can reveal different diet compositions and feeding strategies within a fur seal population

By Nicole Suren, SRC intern Diet analysis of top predators is important in the study of ecology because it can help to illuminate the energetics and ecological interactions of that predator. One method of studying diet is using hard part analysis and DNA barcoding using the animals’ scats, while other methods include stable isotope analysis […]

Spatial Dynamics as an Approach to Fisheries Management

By Casey Dresbach, SRC intern In the last half of the century alone, industrial fisheries have witnessed a global increase in total fishing efforts (Anticamara et al., 2011). Fishing efforts include, but are not limited to: the number of organisms caught, the type of gear used, and the areas in which fish are extracted. Implementation of spatial dynamics into fisheries management will […]
