Heston, Lark (2021-06-01)Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic organic compounds that have a large number of congeners and are used as surfactants in a wide range of consumer products, including firefighting foams, ...
-
Cagle, Sierra Elena (2019-12-03)Harmful algae blooms (HABs)are an increasing problem world-wide. The increasing occurrence and magnitude of HABs has often been linked to anthropogenic disturbances, some of which include salinization, nutrient ratios ...

ASSOCIATION BETWEEN SHRIMP CATCH PER UNIT EFFORT AND ENVIRONMENTAL VARIABLES IN THE GULF OF MEXICO Millberry, Cyrenea (2013-02-04)The commercial shrimp harvest is the second most important fishery in the United States, and eighty percent of this harvest by weight is caught in the Gulf of Mexico (GOM). Survival rate in the post larval stage in GOM ...
-
Pawluk, Michaela Elizabeth (2021-07-12)Climate change is affecting marine environmental conditions which can affect fish distributions, survival, and species interactions. The aim of this dissertation is to address how climate change may affect fish populations ...

Fujiwara, Masami; Pfeiffer, Georgia; Boggess, May; Day, Sarah; Walton, Jay (Scientific Reports, 2011)
-
Diaz-Lopez, Jasmins (2019-08-19)Matrix population models are often applied to a variety of organisms possessing different life history traits, and fertility rates need to be estimated differently for them. Although there is a general method described for ...
-
Fitzgerald, Daniel Bruce (2016-09-30)Increasing hydroelectric development in the tropics is beginning to place a large percentage of global freshwater diversity at risk. A prime example is the recently completed Belo Monte Hydroelectric Complex (BMHC) on the ...
-
Plumlee, Jeffrey David (2018-08-16)Artificial reefs serve as important habitat for several marine fish species in the northwest Gulf of Mexico (NW GoM). Structure type, relief, and depth of artificial reefs have been shown to affect the community composition ...
-
Bower, Luke Max (2019-05-15)A mechanistic understanding of general community assembly is crucial for predicting how species will respond to future environmental changes. My dissertation explores general ecological patterns of stream fish assemblages ...
-
Deep Water Mixing Prevents Harmful Algal Bloom Formation: Implications for Managed Fisheries Refugia Hayden, Natanya Jeanne (2012-10-19)Inflows affect water quality, food web dynamics, and even the incidence of harmful algal blooms. It may be that inflows can be manipulated to create refuge habitat for biota trying to escape poor environmental conditions, ...

Fujiwara, Masami (OMICS Publishing Group, 2014-02-10)Mathematical models for the infection of juvenile Chinook salmon (Oncorhynchus tshawytscha) with Ceratomyxa shasta (a myxozoan parasite) in the Klamath River, California, were developed and parameterized with existing data. ...
-
Livernois, Mariah Christina (2022-07-20)Predators shape ecosystem function through direct and indirect effects on prey populations and other predators. Furthermore, co-occurrence of multiple predators is common in most ecosystems and interactions between them ...
-
Agrawal, Anika (2021-06-16)With intensifying global change ecologists work to understand the effects of anthropogenic and environmental stressors on organisms. Importantly, prior stress can influence population response to later stress. This is often ...
-
Fujiwara, Masami; Mohr, Michael S.; Greenberg, Aaron (PLOS, 2014-01-10)The effects of an increased disease mortality rate on the transient and asymptotic dynamics of Chinook salmon (Oncorhynchus tshawytscha) were investigated. Disease-induced mortality of juvenile salmon has become a serious ...
-
Bokhutlo, Thethela (2020-08-27)Alteration of the flow regime may affect species distributions, mechanisms of community assembly, and patterns of energy flow within and between fluvial ecosystems. Changes in the periodicity and predictability of flows ...
-
Ou, Chouly (2013-11-15)The Mekong River is one of the world’s most important rivers in terms of its size, economic importance, cultural significance, productivity, and biodiversity. The Mekong River’s fisheries and biodiversity are threatened ...
-
Walkup, Danielle Kathryn (2018-08-15)Habitat fragmentation and habitat loss are two of the main drivers of biodiversity loss. This anthropogenic reduction of habitat and the corresponding increasing isolation can lead to negative consequences for biodiversity ...
-
Sierra Castillo, Liliana Paola (2019-08-15)Small-scale fisheries are difficult to assess and manage adequately due to uncertainties surrounding collected data. For example, data are often limited to fishery-dependent data, and fishing gear, such as a gillnet, is ...
