Vertical Ecology Of The Pelagic Ocean: Quantified Patterns And New Perspectives, 2013 Virginia Institute of Marine Science
Vertical Ecology Of The Pelagic Ocean: Quantified Patterns And New Perspectives, Tracey Sutton
Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures
Applications of acoustic and optical sensing and intensive, discrete-depth sampling, in concert with collaborative international research programs, have substantially advanced our knowledge of pelagic ecosystems in the 17 years since the last Deep-water Fishes FSBI Symposium. Although the epipelagic habitat is the best-known, and remote sensing and high-resolution modeling allow near-synoptic investigation of upper layer biophysical dynamics, ecological studies within the mesopelagic and deep-demersal habitats have begun to link lower and upper trophic level processes. Bathypelagic taxonomic inventories are far from complete but recent projects (MAR-ECO and CMarZ, supported by the Census of Marine Life program) have quantitatively strengthened distribution …
Length Structure Of Deep-Pelagic Fishes Sheds New Light To Their Life Histories, 2013 Institute of Marine Research - Norway
Length Structure Of Deep-Pelagic Fishes Sheds New Light To Their Life Histories, M. Heino, David S. Boukal, Tone Falkenhaug, Uwe Piatkowski, F. M. Porteiro, Tracey Sutton
Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures
Here we use a new technique to study life history variation in deep-pelagic fishes from a mid-ocean ridge system. Shape of length distribution in a population is to a significant extent determined by the degree to which an average individual approaches its asymptotic maximum size. Analysing the material from the pelagic trawl hauls taken during the 2004 Mar-Eco expedition along the northern Mid-Atlantic Ridge, we show that length distributions in many deep-pelagic fish species are characterised by negative skew (the left tail of the distribution is longer). In other words, a large proportion of individuals had a size close to …
Intraspecific Relationships In Paracalanus Quasimodo [Calinoideae] And Temora Turbinata [Calinoideae] Along The Southeastern Coast Of The United States, 2013 Florida International University
Intraspecific Relationships In Paracalanus Quasimodo [Calinoideae] And Temora Turbinata [Calinoideae] Along The Southeastern Coast Of The United States, Richard Y. Chang
FIU Electronic Theses and Dissertations
Paracalanus quasimodo and Temora turbinata are two calanoid copepods prominent in the planktonic communities of the southeastern United States. Despite their prominence, the species and population level structure of these copepods is yet unexplored. The phylogeographic, temporal and phylogenetic structure of P. quasimodo and T. turbinata are examined in my study. Samples were collected from ten sites along the Gulf of Mexico and Florida peninsular coasts. Three sites were sampled quarterly for two years. Individuals were screened for unique ITS-1 sequences with denaturing gradient gel electrophoresis. Unique variants were sequenced at the nuclear ITS-1 and mitochondrial COI loci. Sampling sites …

Decades-Long Social Memory In Bottlenose Dolphins, 2013 Stephen F Austin State University
Decades-Long Social Memory In Bottlenose Dolphins, Jason N. Bruck
Faculty Publications
Long-term social memory is important, because it is an ecologically relevant test of cognitive capacity, it helps us understand which social relationships are remembered and it relates two seemingly disparate disciplines: cognition and sociality. For dolphins, long-term memory for conspecifics could help assess social threats as well as potential social or hunting alliances in a very fluid and complex fission-fusion social system, yet we have no idea how long dolphins can remember each other. Through a playback study conducted within a multi-institution dolphin breeding consortium (where animals are moved between different facilities), recognition of unfamiliar versus familiar signature whistles of …

Distribution Of Parasitic Isopods On Caridean Shrimp In South Florida Seagrass Beds, 2013 Nova Southeastern University
Distribution Of Parasitic Isopods On Caridean Shrimp In South Florida Seagrass Beds, Sarah A. Briggs
HCNSO Student Theses and Dissertations
Caridean shrimp are a prominent element of seagrass faunal communities and play an important role in the energy transfer between trophic levels. They are a food source for other organisms and play an integral role in the ecosystem by feeding on algae and assisting with the breakdown of organic matter. Carideans are also fundamental to the marine fishery industry in that they are a food source for potentially valuable juvenile commercial fish. Ectoparasitic isopods (Cymothoida: Bopyridae) that infest caridean shrimps decrease the energy level of the shrimp, resulting in slower reaction time, greater predation rate, slower growth rate, and/or reduced …

Fish Species Distribution In Seagrass Habitats Of Chesapeake Bay Are Structured By Abiotic And Biotic Factors, Jason J. Schaffler, Jacques Van Montfrans, Cynthia M. Jones, Robert J. Orth
OES Faculty Publications
Seagrass habitats have long been known to serve as nursery habitats for juvenile fish by providing refuges from predation and areas of high forage abundance. However, comparatively less is known about other factors structuring fish communities that make extensive use of seagrass as nursery habitat. We examined both physical and biological factors that may structure the juvenile seagrass-associated fish communities across a synoptic-scale multiyear study in lower Chesapeake Bay. Across 3years of sampling, we collected 21,153 fish from 31 species. Silver Perch Bairdiella chrysoura made up over 86% of all individuals collected. Nine additional species made up at least 1% …

Weak Prezygotic Isolating Mechanisms In Threatened Caribbean Acropora Corals, 2013 Florida State University
Weak Prezygotic Isolating Mechanisms In Threatened Caribbean Acropora Corals, Nicole Fogarty, Steven Vollmer, Don Levitan
Steve Vollmer
The Caribbean corals, Acropora palmata and A. cervicornis, recently have undergone drastic declines primarily as a result of disease. Previous molecular studies have demonstrated that these species form a hybrid (A. prolifera) that varies in abundance throughout the range of the parental distribution. There is variable unidirectional introgression across loci and sites of A. palmata genes flowing into A. cervicornis. Here we examine the efficacy of prezygotic reproductive isolating mechanisms within these corals including spawning times and choice and no-choice fertilization crosses. We show that these species have subtly different mean but overlapping spawning times, suggesting that temporal isolation is …
Oyster Bed Mapping In The Great Bay Estuary, 2012-2013, 2013 The Jackson Laboratory
Oyster Bed Mapping In The Great Bay Estuary, 2012-2013, Raymond E. Grizzle, Krystin M. Ward
PREP Reports & Publications
Six major oyster beds (reefs) in New Hampshire are mapped periodically to assess wild oyster populations in the Great Bay Estuary. Data on the spatial extent of the beds are combined with density and other measures to estimate the abundances of live oysters. The first objective of the present project was to determine the spatial extent of these six oyster beds, and to compare the 2012/2013 data with previous mapping efforts. A second objective was twofold: to map the extent of live oyster bottom at selected recent oyster restoration sites, and to map areas where oyster beds have been known …
A Comprehensive And Integrative Reconstruction Of Evolutionary History For Anomura (Crustacea: Decapoda), 2013 Department of Biological Sciences, Florida International University
A Comprehensive And Integrative Reconstruction Of Evolutionary History For Anomura (Crustacea: Decapoda), Heather D. Bracken-Grissom, Maren E. Cannon, Patricia Cabezas, Rodney M. Feldmann, Carrie E. Schweitzer, Shane T. Ahyong, Darryl L. Felder, Rafael Lemaitre
Department of Biological Sciences
Background
The infraorder Anomura has long captivated the attention of evolutionary biologists due to its impressive morphological diversity and ecological adaptations. To date, 2500 extant species have been described but phylogenetic relationships at high taxonomic levels remain unresolved. Here, we reconstruct the evolutionary history—phylogeny, divergence times, character evolution and diversification—of this speciose clade. For this purpose, we sequenced two mitochondrial (16S and 12S) and three nuclear (H3, 18S and 28S) markers for 19 of the 20 extant families, using traditional Sanger and next-generation 454 sequencing methods. Molecular data were combined with 156 morphological characters in order to estimate the largest …
Multiple Approaches For Assessing Mangrove Biophysical And Biochemical Variables Using In Situ And Remote Sensing Techniques, 2013 The University of Western Ontario
Multiple Approaches For Assessing Mangrove Biophysical And Biochemical Variables Using In Situ And Remote Sensing Techniques, Francisco Javier Flores De Santiago
Electronic Thesis and Dissertation Repository
Mangrove forests are important ecosystems and play a key role in maintaining the equilibrium in coastal lagoons and estuaries. However, in recent years, there has been a considerable loss of mangrove extension due to anthropogenic activities. Recent studies suggest that multiple in situ and remote sensing approaches must be carried out to understand the dynamics in these complex ecosystems. Therefore, the objective for this PhD dissertation is to develop multiple techniques for monitoring the seasonal biophysical and biochemical conditions of the mangrove forests. Particular objectives will include: i. Test the feasibility of using a Chlorophyll Content Index from a …

The bony shell of the turtle is an evolutionary novelty not found in any other group of animals, however, research into its formation has suggested that it has evolved through modification of conserved developmental mechanisms. Although these mechanisms have been extensively characterized in model organisms, the tools for characterizing them in non-model organisms such as turtles have been limited by a lack of genomic resources. We have used a next generation sequencing approach to generate and assemble a transcriptome from stage 14 and 17 Trachemys scripta embryos, stages during which important events in shell development are known to take place. …
Ontogenetic Scaling Of The Olfactory Antennae And Flicking Behavior Of The Shore Crab, Hemigrapsus Oregonensis, 2013 Chapman University
Ontogenetic Scaling Of The Olfactory Antennae And Flicking Behavior Of The Shore Crab, Hemigrapsus Oregonensis, Lindsay D. Waldrop
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Malacostracan crustaceans such as crabs flick antennae with arrays of olfactory sensilla called aesthetascs through the water to sense odors. Flicking by crabs consists of a quick downstroke, in which aesthetascs are deflected laterally (splayed), and a slower, reversed return stroke, in which aesthetascs clump together. This motion causes water to be flushed within and then held in between aesthetascs to deliver odor molecules to olfactory receptors. Although this odor sampling method relies on a narrow range of speeds, sizes, and specific arrangements of aesthetascs, most crabs dramatically change these during ontogeny. In this study, the morphometrics of the aesthetascs, …
Effects Of Multiple Ecological Drivers On Recruitment And Succession Of Coral Reef Macroalgal Communities, 2013 Florida International University
Effects Of Multiple Ecological Drivers On Recruitment And Succession Of Coral Reef Macroalgal Communities, Alain Duran
FIU Electronic Theses and Dissertations
The study evaluated the effects of herbivory pressure, nutrient availability and potential propagule supply on recruitment and succession of coral reef macroalgal communities. Recruitment and succession tiles were placed in a nutrient-herbivory factorial experiment and macroalgal abundances were evaluated through time. Proportional abundances of macroalgal form-functional groups on recruitment and succession tiles were similar to field established communities within treatments, evidencing possible effects of adult macroalgae as propagule supply. Macroalgal abundance of recruitment tiles increased with nutrient loading and herbivory reduction combined whereas on succession tiles nutrient loading increased abundance of articulated-calcareous only when herbivores were excluded. Macroalgal field established …
Spatial And Temporal Patterns In Macrofaunal Diversity Components Relative To Sea Floor Landscape, 2013 University of New Haven
Spatial And Temporal Patterns In Macrofaunal Diversity Components Relative To Sea Floor Landscape, Roman Zajac, Brittney R. Gibbons, Joseph M. Vozarik
Biology and Environmental Science Faculty Publications
We examined temporal changes in macrofaunal α- and β-diversity over several spatial scales (within patches, among patches, across landscapes and across regions) in Long Island Sound on the northeast USA coast. Regional ε-diversity was estimated at 144 taxa, however γ-diversity fluctuated over time as did α- and β-diversity components. Based on additive partitioning, patch- and region-scale β-diversity components generally had the highest contributions to γ-diversity; lower percentages were found at within-patch and landscape scales. Multiplicative diversity partitioning indicated highest species turnover at within- and among patch scales. For all partition results, within-patch and patch-scale β-diversity increased sharply when hypoxia impacted …
