(2017-11-14)This study examined the feeding ecology of two reef fishes using gut content and stable isotope analyses to assess the role of artificial reefs as foraging habitat in the Northwest Gulf of Mexico (GoM). Reefs were divided ...
-
(2015-04-29)A key objective of the National Marine Fisheries Service recovery plan for Steller sea lions (SSL – Eumetopias jubatus) is to protect critical habitats. Doing so relies in part on knowledge of SSL ecology based on time-depth ...
-
(2020-09-11)Passive acoustic monitoring is an effective tool for delineating population structure of blue whales (Balaenoptera musculus). Globally, there are at least nine regionally distinct blue whale songs, with two to three distinct ...
-
(2013-08-05)With additional research on species characteristics and continued work towards cost effective production methods, algae are viewed as a possible alternative biofuel crop to current feedstocks such as corn. Current open ...
-
(2023-04-25)Atlantic tarpon (Megalops atlanticus) are capable of long-distance migrations (hundreds of kilometers) but also exhibit resident behaviors in estuarine and coastal habitats. The aim of this study was to characterize essential ...
-
(2021-04-08)New Zealand sea lions (Phocarctos hookeri) were extirpated from the North and South Islands of New Zealand during pre-European native hunting, and their numbers were greatly reduced on the Auckland and Campbell Islands ...
-
(2017-12-09)Hydrozoa (phylum Cnidaria) is one of the most diverse and widespread classes of gelatinous zooplankton. They are understudied because they are often inconspicuous and overlooked in many planktonic studies. Due to their ...
-
(2020-10-29)Microorganisms account for ~70% of the total biomass of the ocean and fill many necessary roles within the ecosystem. However, little is known about how the marine microbial communities respond and recover from environmental ...
-
Impacts of Vessel Noise Perturbations on the Resident Sperm Whale Population in the Gulf of Mexico (2012-07-16)The Gulf of Mexico is home to two of the world?s ten busiest ports by cargo volume, the Port of New Orleans and the Port of Houston; and in 2008, these ports hosted a combined 14,000 ships, a number which is likely only ...
-
(2016-03-01)Understanding how biological components respond to environmental changes could be insightful to predict ecosystem trajectories under different climate scenarios. Zooplankton are key components of marine ecosystems and ...
-
(2015-10-14)Vibrissae, or whiskers, are largest among pinnipeds and are specialized hairs that potentially evolved to serve sensory, thermoregulatory or protective functions. Behavioral data from pinniped and rodent vibrissa studies ...
-
(2017-12-06)Vibrissae, or whiskers, are highly developed sensory structures found in mammals. The follicles are referred to as Follicle Sinus Complexes (F-SC) due to the blood-filled sinuses. F-SCs are highly innervated compared to ...
-
(2020-04-27)The hepatic body-burdens of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) were integrated with fatty acid levels in four fish species from Sabine Lake (TX), namely: bull shark (Carcharhinus ...
-
(2018-05-22)Microbial communities play a vital role at the base of the food web providing and recycling essential nutrients and carbon for larger organisms. Phytoplankton in the ocean are responsible for approximately 50% of global ...
-
(2014-05-07)Estuaries are subjected to variable salinity regimes governed by variable freshwater inflow and tidal regimes. Estuaries are less saline near the river (source of fresh water); salinities increase towards the inlet of the ...
-
(2012-12-10)Ecosystem services are benefits humans receive as a function of natural processes. Many current studies seek to express these benefits as an economic value per unit of habitat type without quantifying the ecological ...
-
(2020-03-25)Iodine, an essential component of thyroid hormone, can only be obtained through the diet. The sodium iodide symporter (NIS) transports iodide across mammalian intestinal and thyroid epithelia to deliver iodide for thyroid ...
-
(2022-06-30)In the northern Gulf of Mexico (GoM), quantitative research on the spatial and temporal relationships between zooplankton and oceanographic processes currently remains insufficient but needed to understand the impacts of ...
-
(2023-03-30)Marine mammal morphometrics contribute to our understanding of their physiology, biomechanics, behavior, ecology, and conservation. The morphometric variables of body dimensions, volume, and mass are challenging to obtain, ...
-
(2016-04-18)This dissertation provides broad insights on aspects of sexual selection in cetaceans (whales, dolphins, and porpoises) and addresses the gap of knowledge regarding female mating strategies. A comparative approach is applied ...
