Anthropogenic Change On The Distribution Of Marine Megafauna And Their Prey, Baylie Fadool
Anthropogenic Change On The Distribution Of Marine Megafauna And Their Prey, Baylie Fadool
Honors Theses
Anthropogenic change is impacting the distribution and survival of marine megafauna and their prey. Humans are changing every aspect of the marine environment, with effects reaching as large as changing the composition of marine environments to directly overexploiting species through the fishing industry. The role that marine megafauna play in balancing ecosystems, including as top apex predators, leads to detrimental results in the absences and population declines of these species. Migrations and declines due to threats on marine apex predator species will alter their environments by causing mesopredator release and changes in community structure, which is often associated with reduced …
Atlantic Spotted Dolphin (Stenella Frontalis) And Bottlenose Dolphin (Tursiops Truncatus) Nearshore Distribution, Bimini, The Bahamas, Skylar L. Muller
Atlantic Spotted Dolphin (Stenella Frontalis) And Bottlenose Dolphin (Tursiops Truncatus) Nearshore Distribution, Bimini, The Bahamas, Skylar L. Muller
HCNSO Student Theses and Dissertations
Bimini, The Bahamas, includes two islands surrounded by a diverse assemblage of ecosystems and a large array of organisms, including two delphinid species, Atlantic spotted dolphins (Stenella frontalis) and common bottlenose dolphins (Tursiops truncatus, inshore ecotype). Within a predefined nearshore zone, individuals of both species had largely overlapping distribution from 2003-2018; Atlantic spotted dolphins tended to disperse farther to the north while bottlenose dolphins were located farther south. The distribution of both species varied significantly by year. Atlantic spotted dolphin sightings varied across years and months while bottlenose dolphin sightings varied by month, with differences between …

Landscape context is critical in estuary restoration planning and assessment due to the complexity and size of estuaries, and the unique attributes and cumulative effects of individual restoration projects. In addition, the diversity and mobility of estuarine species, in particular juvenile salmon, highlights the importance of landscape position given certain locations in the delta are less accessible to salmon. The Snohomish River delta has been the focus of major estuary restoration efforts in recent years and efforts could result in the largest cumulative estuary restoration action in Puget Sound. While several large projects have been initiated/competed in recent years, information …

Characterizing habitat suitability for a marine predator requires an understanding of the environmental heterogeneity and variability over the range in which a population moves during a particular life cycle. Female California sea lions (Zalophus californianus) are central‐place foragers and are particularly constrained while provisioning their young. During this time, habitat selection is a function of prey availability and proximity to the rookery, which has important implications for reproductive and population success. We explore how lactating females may select habitat and respond to environmental variability over broad spatial and temporal scales within the California Current System. We combine near‐real‐time …
Distribution And Condition Of Stony Corals In The Veracruz Reef System National Park: A Management Perspective, Mauricio López Padierna
Distribution And Condition Of Stony Corals In The Veracruz Reef System National Park: A Management Perspective, Mauricio López Padierna
HCNSO Student Theses and Dissertations
The Veracruz Reef System (VRS) is located in the southwestern Gulf of Mexico. It is comprised of 28 coral reefs in various stages of development and conservation. They are protected under the Parque Nacional Sistema Arrecifal Veracruzano National Park created in 1992. There are many threats to the reefs of the VRS, including the Port and city of Veracruz, which hosts half a million inhabitants and Mexico’s oldest active port. The inhabitants of Veracruz have used reef resources for thousands of years, as evidenced in archaeological sites on Sacrificios island, and constructions throughout the city, most notably in the San …
Investigating The Spatial Distribution And Effects Of Nearshore Topography On Acropora Cervicornis Abundance In Southeast Florida, Nicole D'Antonio, David S. Gilliam, Brian K. Walker
Investigating The Spatial Distribution And Effects Of Nearshore Topography On Acropora Cervicornis Abundance In Southeast Florida, Nicole D'Antonio, David S. Gilliam, Brian K. Walker
Marine & Environmental Sciences Faculty Articles
Dense Acropora cervicornis aggregations, or patches, have been documented within nearshore habitats in Southeast Florida (SE FL) despite close proximity to numerous anthropogenic stressors and subjection to frequent natural disturbance events. Limited information has been published concerning the distribution and abundance of A. cervicornis outside of these known dense patches. The first goal of this study was to conduct a spatially extensive and inclusive survey (9.78 km2) to determine whether A. cervicornis distribution in the nearshore habitat of SE FL was spatially uniform or clustered. The second goal was to investigate potential relationships between broad-scale seafloor topography and …
Connectivity Of Coastal And Oceanic Ecosystems: Pelagic Habitat Use By Juvenile Reef Fishes In The Gulf Of Mexico, Katie Bowen
Connectivity Of Coastal And Oceanic Ecosystems: Pelagic Habitat Use By Juvenile Reef Fishes In The Gulf Of Mexico, Katie Bowen
HCNSO Student Theses and Dissertations
The assemblage structure, abundance, biomass, and vertical distribution of juvenile reef fishes in the offshore pelagic habitat of the northern Gulf of Mexico are described as part of the NOAA-supported Offshore Nekton Sampling and Analysis Program. The results presented here are from a 3-month, continuous sampling series in 2011 in which discrete depth strata from 0 to 1500 m were sampled using a 10-m2 MOCNESS midwater trawl. This is the first study to examine pelagic juvenile reef fish distributions across the entire oceanic northern Gulf of Mexico seaward of the continental shelf break after the Deepwater Horizon Oil Spill. …
Segregation Of Palaemonid Shrimp Along The Shark River Estuary: Implications For Trophic Function, Lauren C. Mccarthy
Segregation Of Palaemonid Shrimp Along The Shark River Estuary: Implications For Trophic Function, Lauren C. Mccarthy
HCNSO Student Theses and Dissertations
This study examined the abundance, distribution, and spatiotemporal variation of palaemonid shrimp species in relation to season and salinity in the Shark River Estuary, Everglades National Park (ENP), Florida, USA. Five palaemonid species occurred in the samples: Palaemonetes paludosus, P. pugio, P. intermedius, Palaemon floridanus, and Leander paulensis; L. paulensis was collected only during the wet season. Overall, shrimp catches in traps doubled in the dry season. Catches in the upper estuary were dominated by P. paludosus, particularly in the wet season, while catch per unit effort (CPUE) at the most downstream, …
Grazing Impacts Of Diverse Zooplankton Taxa On Thin Layers, Alexander Bochdansky
Grazing Impacts Of Diverse Zooplankton Taxa On Thin Layers, Alexander Bochdansky
OES Faculty Publications
The US Navy needs to know how distributions and abundances of light-scattering and sound-scattering organisms in the ocean vary in space and time, particularly in the vertical dimension. Recent field observations have shown that many biological properties may vary substantially over small e.g. centimeter scales, commonly referred to as thin layers e.g. Cowles et al. 1998, 1999, Hanson Donaghay 1998, Holliday et al. 1999, Dekshenieks et al. 2001, Alldredge et al. 2002, Rines et al. 2002. Our previous ONR-funded research has allowed us to begin to understand how zooplankton interact with thin layers and how they can take advantage of …
