Low Florida Coral Calcification Rates In The Plio-Pleistocene, Thomas C. Brachert, Markus Reuter, Stefan Kruger, James S. Klaus, Kevin P. Helmle, Janice M. Lough

Marine & Environmental Sciences Faculty Articles

In geological outcrops and drill cores from reef frameworks, the skeletons of scleractinian corals are usually leached and more or less completely transformed into sparry calcite because the highly porous skeletons formed of metastable aragonite (CaCO3) undergo rapid diagenetic alteration. Upon alteration, ghost structures of the distinct annual growth bands often allow for reconstructions of annual extension ( =  growth) rates, but information on skeletal density needed for reconstructions of calcification rates is invariably lost. This report presents the bulk density, extension rates and calcification rates of fossil reef corals which underwent minor diagenetic alteration only. The corals derive from …

Graphodatsky, Vladimir Trifonov

Biology Faculty Articles

Background

B chromosomes are dispensable and variable karyotypic elements found in some species of animals, plants and fungi. They often originate from duplications and translocations of host genomic regions or result from hybridization. In most species, little is known about their DNA content. Here we perform high-throughput sequencing and analysis of B chromosomes of roe deer and brocket deer, the only representatives of Cetartiodactyla known to have B chromosomes.

Results

In this study we developed an approach to identify genomic regions present on chromosomes by high-throughput sequencing of DNA generated from flow-sorted chromosomes using degenerate-oligonucleotide-primed PCR. Application of this method …

Fish Communities Associated With Cold-Water Corals Vary With Depth And Substratum Type, Rosanna Milligan, Gemma Spence, J. Murray Roberts, David M. Bailey

Marine & Environmental Sciences Faculty Articles

Understanding the processes that drive the distribution patterns of organisms and the scales over which these processes operate are vital when considering the effective management of species with high commercial or conservation value. In the deep sea, the importance of scleractinian cold-water corals (CWCs) to fish has been the focus of several studies but their role remains unclear. We propose this may be due to the confounding effects of multiple drivers operating over multiple spatial scales. The aims of this study were to investigate the role of CWCs in shaping fish community structure and individual species-habitat associations across four spatial …

Coral Persistence To Ocean Warming Via Developmental Acclimation, Heather L. Schaneen

HCNSO Student Theses and Dissertations

Scleractinian corals are the ‘engineers’ of tropical coral reef ecosystems. Their three-dimensional structure provides habitat for thousands of fish and invertebrate species. The persistence of corals is threatened by climate change. In this study I investigated if corals may be able to increase tolerance to ocean warming through developmental acclimation, i.e. if corals that experience warmer temperatures during embryonic and larval development are better able to cope with higher temperatures later in life. Larvae of the broadcast spawning coral Montastraea cavernosa were raised at ambient (29°C) and future projected ocean warming temperatures (+2°C, 31°C). After larval settlement, coral juveniles from …

Fibropapillomatosis In Marine Turtles: A Comprehensive Review, Samantha L. Mccorkle

HCNSO Student Capstones

Fibropapillomatosis is a disease that affects six of the seven species of marine turtles. The disease was first noticed in 1928, and wasn’t observed again until the 1970s. By the 1980s there was a rapid spread of fibropapillomatosis through the sea turtle population, becoming an endemic in both Florida and Hawaii. By 1995 the concentration of disease in the population reached its climax and has showed a decline in prevalence since. After identifying a viral cause studies began to focus on cultivating the virus in the lab and sequencing, while the virus has been sequenced it has not been successfully …

A total of 6,015 cetaceans stranded at 36 locations from 24 peer reviewed articles published between 1999 and 2014 are documented, with the two most common stranding locations being the Canary Islands - accounting for 49 of the total cetacean stranding events - and Cape Cod - accounting for 31 of total cetacean stranding events. The documented cetacean stranding events included 805 for bottlenose dolphins (Tursiops truncatus) at a total of ten locations from 11 peer reviewed articles. When all single stranding …

Transgenerational Effects Of Thermal Stress: Impacts On And Beyond Coral Reproduction, Alyson Kuba

HCNSO Student Theses and Dissertations

Ocean warming causes stress to corals and records reveal that periods of thermal stress are increasing in frequency and severity. Previous studies show that thermal stress negatively impacts the reproductive output of corals. However, the transgenerational impacts of coral bleaching have never been quantified. As a consequence, it is unclear how ocean warming may alter population dynamics due to effects on reproduction and recruitment. This study quantified the transgenerational impacts of thermal stress in Montastraea cavernosa. To assess transgenerational effects of temperature stress during gametogenesis, colonies were exposed to elevated temperature for two weeks four months prior to spawning, …

Can Skeletal Morphology Support New Molecular Phylogenies Of Antedonidae (Crinoidea: Comatulida)?, Brenna Hays

HCNSO Student Theses and Dissertations

Antedonidae (Crinoidea: Comatulida) is the largest of extant crinoid families; it currently includes ~155 accepted species in 50 genera and accounts for ~23% of extant crinoid species (~29% of feather stars) and 27% of genera. Molecular phylogenies have returned the family as polyphyletic, with several clades scattered among non-antedonid sister groups (Hemery 2011, Hemery et al. 2013, Rouse et al. in prep.). Traditional morphological characteristics are thus inadequate for reconstructing relationships among taxa. SEM imaging was used in an effort to discover new diagnostic features that will support the molecular data, focusing on skeletal ossicles within the calyx, specifically the …

Artificial Reefs As Juvenile Fish Habitats In Marinas, Allison Patranella

HCNSO Student Theses and Dissertations

Coastal infrastructure has replaced many vital fish nursery habitats with structures designed without fully mitigating for the loss of the natural ecosystems. This thesis details research focused on the use of small, inexpensive, artificial reef modules as replacement juvenile fish habitat within marinas. My research hypothesis was that the placement of small, structurally complex artificial reef modules would increase fish abundance and species richness relative to unmodified marina seawalls. Non-destructive visual surveys of fishes were completed monthly for 14 months for 12 artificial reef sites and 12 control (unmodified) sites within the Nova Southeastern University Guy Harvey Oceanographic Center (NSU-GHOC) …

Reproductive Ecology Of Dragonfishes (Family: Stomiidae) In The Gulf Of Mexico, Alex D. Marks

HCNSO Student Theses and Dissertations

The most speciose group of fishes in the Gulf of Mexico is the dragonfishes (Family: Stomiidae). These fishes are dominant mesopelagic predators occurring throughout the world’s oceans, including the Antarctic seas. Little is known regarding their reproductive ecology, a consequence attributed to insufficient sample sizes of mature adults due to inadequacies of sampling gear; larger, sexually mature stomiid adults are more adept at net avoidance, thereby obfuscating synoptic reproductive biology studies. Between 2010-2011, the Offshore Nekton Sampling and Analysis Program was initiated in the northern Gulf of Mexico over all four seasons using a discrete-depth sampling system (MOCNESS) and a …

Changes In Tursiops Truncatus Distribution And Behavior In The Drowned Cayes, Belize, And Correlation To Human Impacts, Jazmin Garcia

HCNSO Student Theses and Dissertations

Human interaction greatly influences the behavior and distribution of bottlenose dolphins (Tursiops truncatus). This project focuses on the distribution and behavior of bottlenose dolphins in the Drowned Cayes, Belize. Prior to the 2000s, the area was relatively undeveloped and undisturbed and had minimal human activity. Since the turn of the millennium, development and ecotourism activity has flourished in the area, increasing by more than 800,000 visitors from 1998-2006. Boat-based surveys were conducted in 2015 and were combined with previous survey data collected from 2005-2012 and compared to behavioral survey results from 1999-2000. Total dolphin observation time as a …

Can Twilight Reefs Usher In A New Dawn For Depauperate Shallow Coral Reefs?, Hunter Kg Noren

HCNSO Student Theses and Dissertations

As shallow reefs continue to decline, scientists are searching for the key to their persistence; as it turns out, they may just need to look deeper. Below many shallow tropical reefs, there exist healthy and more stable mesophotic coral reef communities. The ability of these reefs to act as a refuge for declining shallow populations has garnered significant interest among the scientific community; however, the reproductive and larval aspects necessary for this to occur are unknown. This study assesses the ability of deep reefs to act as a reproductive refuge for shallow counterparts by examining gametic compatibility, viability and larval …

Using Regression-Based Effect Size Meta-Analysis To Investigate Coral Responses To Climate Change, Niklas Alexander Kornder

HCNSO Student Theses and Dissertations

Attempts to quantify the effects of ocean acidification and warming (OAW) on scleractinian corals provide a growing body of response measurements. However, placing empirical results into an ecological context is challenging, owing to variations that reflect both natural heterogeneity and scientific bias. This study addresses the heterogeneity of climate change induced changes in coral recruitment and calcification. To discern scientific bias and identify drivers of the remaining heterogeneity, 100 publications were analyzed using a combination of weighted mixed effects meta-regression and factorial effect size meta‑analysis. A linear model was applied to quantify the variation caused by differing stress levels across …

Establishing An Ecological Baseline Of Macroinfaunal Assemblages In Nearshore Sediments Of Southeast Florida, Candace Grimes

HCNSO Student Theses and Dissertations

Changes in the biosphere require ecological baselines in order to compare past, present, and future conditions and identify their effects. Establishing ecological baselines for infauna in southeastern Florida is a key component to understanding effects of current and future disturbances; however, nearshore sediment infaunal communities are neither as thoroughly investigated nor as well understood as, for example, coral reefs, seagrass beds, and mangroves. Baseline studies help assess and monitor changes due, for example, to human population growth, sea level change, and global warming. Therefore, six benthic cores were collected quarterly from six locations from May 2015 to February 2016 using …

Perceptions Of Being A Woman And Strategies For Women’S Body Image Resilience, Lauren L. Mclean, Amanda C. Laguardia

The Qualitative Report

Although the negative effects of female body objectification are well established, there is a lack of qualitative research examining how women can develop resiliency against body image issues and low self-esteem. Through the current phenomenological qualitative study, we sought to explore how participants defined being a woman, particularly a woman with healthy self-esteem. In addition, we explored several resiliency strategies, based on Choate’s (2005) theoretical model of body image resilience, that women could potentially use to combat some of the effects of objectification. Results indicated that female participants experience normative beliefs and gender expectations that a woman with a healthy …

Sponges (phylum Porifera) are early-diverging metazoa renowned for establishing complex microbial symbioses. Here we present a global Porifera microbiome survey, set out to establish the ecological and evolutionary drivers of these host–microbe interactions.We show that sponges are a reservoir of exceptional microbial diversity and major contributors to the total microbial diversity of the world’s oceans. Little commonality in species composition or structure is evident across the phylum, although symbiont communities are characterized by specialists and generalists rather than opportunists. Core sponge microbiomes are stable and characterized by generalist symbionts exhibiting amensal and/or commensal interactions. Symbionts that are phylogenetically unique to …

Recovered Voices: Experiences Of Borderline Personality Disorder, Carla D. Chugani

The Qualitative Report

The purpose of this article is to use poetic analysis to present evocative accounts of the lived experiences of individuals who have recovered from Borderline Personality Disorder (BPD). Individuals with BPD suffer from a complex set of clinical issues that may be worsened by stigmatization encountered in their general lives as well as from health care providers. I argue that one method of enhancing clinical service provision to individuals with BPD is to view their behavior within the context that it originally developed. Viewing behavior in context may enhance healthcare providers’ abilities to respond empathically and/or to assist clients in …

High-resolution genetic and physical maps are invaluable tools for building accurate genome assemblies, and interpreting results of genome-wide association studies (GWAS). Previous genetic and physical maps anchored good quality draft assemblies of the domestic cat genome, enabling the discovery of numerous genes underlying hereditary disease and phenotypes of interest to the biomedical science and breeding communities. However, these maps lacked sufficient marker density to order thousands of shorter scaffolds in earlier assemblies, which instead relied heavily on comparative mapping with related species. A high-resolution map would aid in validating and ordering chromosome scaffolds from existing and new genome assemblies. Here, …
