Historical Ecology Of The San Diego Sport Fishery: Catch Composition, Species Trends, And Fishing Effort From 1959 To 2011, Rebecca Schwartz Lesberg
Theses
Like ocean systems around the world, species targeted by the San Diego sportfishery are subject to myriad threats from human activity, with several species already showing documented decline. However, long-term fisheries datasets are often lacking, limiting natural resource managers’ ability to appropriately manage these ecologically and economically important species. Therefore, this study used daily reports published in two Southern California newspapers to examine changes in catch composition, effort, and catch per unit effort (CPUE) from 1959-2011 for the San Diego commercial passenger fishing vessel (CPFV) sportfishery. This study then tested the relationship between those patterns and three large scale oceanographic …

All HCAS Student Capstones, Theses, and Dissertations
Dragonfishes (Family Stomiidae) are considered the most numerically important and diverse taxon of higher-level meso- and bathypelagic predators in oceanic food webs, with the subfamily Melanostomiinae contributing 220 of the 317 species. The Stomiidae is also the most speciose fish family in the Gulf of Mexico. The relationship between diversity (both systematic and morphological) and feeding of the Melanostomiinae has not been previously examined due to sample size limitation. Here the diet and morphology of 16 species of dragonfishes in the Gulf of Mexico was examined to address the question, “Does the extraordinary speciation in this most-diverse deep-pelagic fish clade …

School of Earth, Environmental, & Marine Sciences Faculty Publications
As the effects of anthropogenic climate change become more severe, several approaches for deliberate climate intervention to reduce or stabilize Earth’s surface temperature have been proposed. Solar radiation modification (SRM) is one potential approach to partially counteract anthropogenic warming by reflecting a small proportion of the incoming solar radiation to increase Earth’s albedo. While climate science research has focused on the predicted climate effects of SRM, almost no studies have investigated the impacts that SRM would have on ecological systems. The impacts and risks posed by SRM would vary by implementation scenario, anthropogenic climate effects, geographic region, and by ecosystem, …

Bycatch Reduction Devices As A Method To Reduce Mortality Rates Of Malaclemys Terrapin In Crab Pots, Benjamin Lowstuter, Leslie Delong, Corey Hymel
Showcase of Osprey Advancements in Research and Scholarship (SOARS)
Diamondback terrapins (Malaclemys terrapin) currently face population loss along their broad coastal North American range, spanning from Massachusetts down to Texas. This species is suggested to be an important indicator of environmental change within the limited brackish water habitat along the coastlines. Terrapin mortality predominantly stems from human activities, such as commercial and recreational blue crab (Callinectes sapidus) trapping. Once caught in one of many crab pots littered throughout their aquatic habitat, terrapins can easily drown in several hours upon capture. In reviewing published research, the use of bycatch reduction devices (BRDs) have been shown to reduce the number of …

The epithelium of vertebrates is a complex tissue that houses a large variety of cells with different functions. One of its most important functions is protection and in many cases this function is achieved by exuding copious amounts of mucous that fight off diseases, harmful toxins and overall protect the species from external invaders. Mucous, made of mucin, is produced by specialized epithelial cells called goblet cells. Among vertebrates’, fishes are perhaps one of the major groups known to produce mucous, particularly stingrays. The Atlantic stingray, Dasyatis sabina is one of the few cartilaginous fishes known to inhabit both freshwater …

Widespread and large populations of the exotic eastern Pacific ophiuroid brittle star Opthiothela mirabilis now occur in southeastern Florida, extending the range of this recently introduced species from southern Brazil northward to the eastern Caribbean Sea and Florida. The Florida brittle stars, representing two lineages, are epibionts on shallow (3-18 m depth), tropical/subtropical plexaurid (e.g., Eunicea spp., Muricea elongata) and gorgoniid (Antillogorgia spp.) octocorals. The scope of this study includes recent distributional records of O. mirabilis in south Florida, field abundances in relation to the cohabiting endemic ctenophore Coeloplana waltoni, behavioral observations of the ophiuroid, ctenophore and …
