Forage fishes play an important role in marine ecosystems by transferring energy and nutrients through the food web. The population dynamics of forage species can therefore have cascading effects across multiple trophic levels. Here, we analyzed a 19-year dataset on Pinfish (Lagodon rhomboides) across four eastern Gulf of Mexico estuaries to investigate population dynamics, inter- and intra-annual synchrony, metapopulation portfolio effects, growth, and habitat effects. Young-of-year growth rates did not differ among estuaries. The population dynamics of these four systems were stable in the long-term, but highly dynamic inter-annually. Intra-annual dynamics were stable and predictable despite variation in long-term means. …
Evaluation Of Diet Matrix Uncertainty For The Atlantis Model, Cameron Ainsworth
Evaluation Of Diet Matrix Uncertainty For The Atlantis Model, Cameron Ainsworth
C-IMAGE data
We conducted 1000 Atlantis simulations, using permutated diet matrices created by drawing from a beta distribution that represented uncertainty in predator diet. We also employed a statistical emulator which simulates the production of many more Atlantis runs than could be achieved through numerical simulation. This dataset includes 3 products: statistical emulator output, diet matrices, and Atlantis simulations. These are each contained in their own zip file.
Response To Nitrogen And Salinity Conditions In Rhizophora Mangle Seedlings Varies By Site Of Origin, Kristen L. Langanke
Response To Nitrogen And Salinity Conditions In Rhizophora Mangle Seedlings Varies By Site Of Origin, Kristen L. Langanke
USF Tampa Graduate Theses and Dissertations
Many coastal plant species thrive across a range of environmental conditions, often displaying dramatic phenotypic variation in response to environmental variation. We characterized the response of the critical foundation species Rhizophora mangle L. to full factorial combinations of salt and nitrogen (N). We used seedlings collected from five populations and measured traits related to salt tolerance and N amendment. The response to increasing salt included significant plasticity in succulence, leaf mass area (LMA), and root to shoot ratio (R:S). Seedlings also showed overall reduced maximum photosynthetic rate in response to N amendment, but this response depended on the level of …
Remote Estimation Of Biomass Of Ulva Prolifera Macroalgae In The Yellow Sea, Lianbo Hu, Chuanmin Hu, He Ming-Xia
Remote Estimation Of Biomass Of Ulva Prolifera Macroalgae In The Yellow Sea, Lianbo Hu, Chuanmin Hu, He Ming-Xia
Marine Science Faculty Publications
Since 2008, macroalgal blooms of Ulva prolifera (also called green tides) occurred every summer in the Yellow Sea (YS), causing environmental and economic problems. A number of studies have used satellite observations to estimate the severity of the blooms through estimating the bloom size and duration. However, a critical bloom parameter, namely biomass, has never been objectively determined due to lack of measurements. In this study, laboratory experiments were conducted to measure U. prolifera biomass (wet weight) per unit area and the corresponding spectral reflectance, through which a robust relationship has been established to link biomass per area to …
Zooplankton Biomass On The West Florida Shelf, July 2010 – August 2014, Kendra L. Daly
Zooplankton Biomass On The West Florida Shelf, July 2010 – August 2014, Kendra L. Daly
C-IMAGE data
Zooplankton have high temporal and spatial variability. Therefore, they need to be assessed before oil impact and regularly thereafter, to interpret what changes are causally related to oil spills. We surveyed plankton using bongo net tows and the USF SIPPER imaging system to evaluate the variation in plankton abundance on the west Florida shelf and the northern Gulf of Mexico. Seasonal CTD, chlorophyll, nutrient, and zooplankton abundance data from the northeastern Gulf of Mexico and the west Florida shelf. Developed new algorithms for data mining SIPPER (Shadow Imaging Particle Profiler and Evaluation Recorder) camera particle imaging data.
Atp Luminescence Assay As A Bioburden Estimator Of Biomass Accumulation In Caves, Janez Mulec, Andreea Oarga-Mulec
Atp Luminescence Assay As A Bioburden Estimator Of Biomass Accumulation In Caves, Janez Mulec, Andreea Oarga-Mulec
International Journal of Speleology
A commercially available adenosine triphosphate (ATP) detection system (Hygiena, USA), supported by cultivable microbial indicators, was used to estimate bioburden in different habitats in and outside show caves: air, water and solid surfaces. A strong positive correlation between ATP concentration expressed as Relative Light Units (RLU) and Colony-Forming-Units (CFU) was observed for swab samples from cave surfaces. In terms of ATP units, surfaces in a single cave system (Postojna Cave) varied considerably (240-1,258,800 RLU/ 20 cm2) and commonly exceeded the bioburden level of analogues on the surface (0-114,390 RLU/ 20 cm2). Cave sub-habitats were colonized by …

BACKGROUND: Local adaptation, the differential success of genotypes in their native versus foreign environment, arises from various evolutionary processes, but the importance of concurrent abiotic and biotic factors as drivers of local adaptation has only recently been investigated. Local adaptation to biotic interactions may be particularly important for plants, as they associate with microbial symbionts that can significantly affect their fitness and may enable rapid evolution. The arbuscular mycorrhizal (AM) symbiosis is ideal for investigations of local adaptation because it is globally widespread among most plant taxa and can significantly affect plant growth and fitness. Using meta-analysis on 1170 studies …

Zooplankton Dry Weight Biomass Data For The Northeastern Gulf Of Mexico And West Florida Shelf: June 2012 – August 2014, Kendra L. Daly
C-IMAGE data
This dataset contains zooplankton dry weight biomass calculated from samples collected during RV Weatherbird II and RV Bellows cruises from June 2012 to August 2014. Zooplankton was collected using towed bongo nets from the northeastern Gulf of Mexico and the west Florida shelf. The contents of the dataset are an assessment of the seasonal and interannual changes in zooplankton biomass after the Deepwater Horizon oil spill.
Characterization And Fluorescence Of Yellow Biofilms In Karst Caves, Southwest Slovenia, Janez Mulec, Andreea Oarga-Mulec, Rok Tomazin, Tadeja Matos
Characterization And Fluorescence Of Yellow Biofilms In Karst Caves, Southwest Slovenia, Janez Mulec, Andreea Oarga-Mulec, Rok Tomazin, Tadeja Matos
International Journal of Speleology
Biofilms of different colours that colonize surfaces within karst caves represent a source of nutrients. They occur commonly and abundantly at sites with sediments, and close to seepages or underground rivers. Golden-yellow subaerial biofilms are particularly well observed because of their contrast with their surroundings, the characteristics of the pigment and recently, even more, due to the characteristics of light-emitting diode (LED) illumination. Yellow microbial biofilms were sampled from three caves in southwestern Slovenia, Dimnice, Križna jama and Sveta jama. The highest concentration of cultivable microbes (2.33×108 CFU/g) and the biggest number of identified bacteria (66.0%) were retrieved from …

High bycatch of non-target species and species of conservation concern often drives the implementation of fisheries policies. However, species- or fishery-specific policies may lead to indirect consequences, positive or negative, for other species or fisheries. We use an Atlantis ecosystem model of the Northern Gulf of California to evaluate the effects of fisheries policies directed at reducing bycatch of vaquita (Phocoena sinus) on other species of conservation concern, priority target species, and metrics of ecosystem function and structure. Vaquita, a Critically Endangered porpoise endemic to the Upper Gulf of California, are frequently entangled by finfish gillnets and shrimp driftnets. We …
