My interests lie broadly in studying how depth affects coral ecology. Particularly, I aim to assess relationships between depth and corals in terms of coral-zooxanthella symbioses and community structure. Much of the mesophotic and deep sea remains understudied because of the difficulty associated with accessing such remote ecosystems, but their ecological importance merits continued study. I hope to use my research to add to the existing body of work done in these systems.
I am interested in predator-prey interactions between bacteriophages and bacteria in aquatic microbial communities. My research focuses on disruptions to these interactions from changing environmental conditions, and the consequences of disruption on bacterial population dynamics.
I am interested in social behavior and how interactions among conspecifics can drive evolutionary processes. Currently, I am studying the effects of male-male competition and female preference on the maintenance of genetic diversity in Trinidadian guppies. Pronouns: she/her/hers
My research interests lie in the field of fisheries ecology, more specifically with respect to elasmobranchs and their interactions with other fishes. As part of my masters research, I will be coordinating fishery-independent gillnet and longline surveys in the Florida Big Bend to continue the long-term monitoring of shark and teleost communities in this area, and use this data to investigate temporal and spatial variation in trophic interactions with the help of stable isotope analysis.
(she/her/hers) I study sponges and their associated mesofauna to examine the ecology and evolution of mutualisms. I am currently exploring how habitat and sponge host influence the diversity and abundance of associated symbionts using field manipulations in the Florida Keys and Panama.
My research focuses on the ecological costs of predation risk and how the long-term effect of non-lethal predation influences reproduction, behavior and response of the molecular stress network. I am interested in how animals may or may not acclimate to predators over time and how natural selection may modify endocrine/behavioral responses to stress.
I am interested in many aspects of the ecology of marine fishes. My dissertation research focuses on community ecology of six species of deepwater sharks, particularly on differences in trophic ecology and competition based on taxonomy and depth habitat. I am also studying the effect of trophic ecology on toxicology by studying methylmercury contamination in shark muscle tissue.
In the Houle lab, I use experimental evolution/artificial selection and whole-genome resequencing, to research parallel genetic evolution between evolved populations of D. melanogaster and D. simulans. These two closely related species offer the ability to evaluate the predictability of genetic evolution in response to an identical selection pressure.
I am generally interested in animal behavior, evolution and genetics. Currently I am investigating how variation in social environment may explain the maintenance of phenotypic variation. My dissertation work focuses on how genes, social environment and gene by social environment interactions influence the development of male behavioral and life history traits in sailfin mollies (Poecilia latipinna). I am also addressing how males with different life histories vary in fitness across social contexts.
I am broadly interested in community ecology and the effects of anthropogenic stressors on organismal physiology and ecology. To date, my research has focused on ecological interactions of organisms on coral reefs and the effects of ocean acidification on algal ecology and physiology. My current PhD dissertation research focuses on the role of parrotfish behavior in driving spatial variation in benthic community structure and bioerosion on the fringing coral reefs of Bonaire, Netherlands.
I am broadly interested in the ecology and evolution of interacting populations. In particular, my research addresses how intraspecific variation and spatial scale mediate species interactions and scale up to influence population-level outcomes. My dissertation work links the effects of conspecific density on individuals and the effects of density on populations using mathematical models and experiments with the leaf beetle, Leptinotarsa juncta.
Iï¿½m generally interested in the community ecology of marine fishes, with particular focus on elasmobranchs. For my dissertation I am investigating the effects of a seasonal migration of Blacktip sharks, Carcharhinus limbatus, on coastal seagrass communities in the Florida Big Bend, and I am using this system to evaluate evidence for either top-down control from a single predator species or diffuse predation through several species occupying similar trophic levels.
I am broadly interested in better understanding the evolution and ecology of microbial symbionts in the digestive system of fish. In particular, I'm interested in identifying the role of digestive system microbial symbionts in alleviating the nutrient loading stress in local freshwater systems, using metagenomic and metaproteomic analysis of key microbial species, to determine contribution to adaptation.
My research focuses on the potential for evolutionary rescue in marine invertebrates with complex life cycles. I take a quantitative genetics approach to estimate additive genetic variance in, and genetic correlations between, traits in larval and adult life stages. To estimate these variances and correlations, I conduct breeding designs and environmental manipulations using Molgula occidentalis and Bugula neritina, two invertebrates found in nearby shallow subtidal waters.
Rare species are rare for different reasons and in different ways, and understanding the causes of rarity will help refine predictions for the consequences of biodiversity loss. I am interested in understanding what makes a species rare and how some are able to persist at a stable size while others are threatened with imminent extinction. I will conduct field demographic studies to compare rare and common sister taxa, and complement these with manipulations of factors that can promote rarity to identify features that differentiate rare species that are stable from rare species that are threatened by extinction.
I am broadly interested in understanding how anthropogenic pollution is affecting marine environments. I am particularly interested in how the presence of microplastics changes nutrient availability in subtidal sediments. My current research focuses on quantifying the effects of microplastics on marine biogeochemistry, specifically carbon and nitrogen cycling, in the subtidal sediments of the northeastern Gulf of Mexico.
My research has two primary directions. The first uses 16s rRNA sequencing to describe endophytic bacterial diversity in mangrove trees, especially Rhizophora mangle. The second direction uses RADseq methods to investigate the ongoing range expansion of R. mangle into the Florida Panhandle and aims to determine the relative importance of long and short-distance dispersal.
My interests include population dynamics, distributions and evolution of (mostly marine and aquatic) organisms, along with development of new quantitative modeling approaches. A current focus of research is eco-evolutionary impacts of harvest on populations.
My goal is to advance our understanding of how trophic dynamics and environmental change affect the metabolic ecology of size-structured populations. I currently study marine invertebrates in temperate kelp forest ecosystems as model organisms for understanding these dynamics. In the past, I have also studied the physiological ecology of tropical corals and calcifying algae under environmental pressure from ocean acidification.
I am interested in how phenotypic and genetic variation are maintained in ecologically relevant traits that are under strong natural selection. I examine this by looking at the behavioral and genomic mechanisms underlying female mate preference and the maintenance of polymorphism in Trinidad guppies (Poecilia reticulata) and their close relatives, Poecilia picta.
I am interested in ecological processes and community dynamics that occur on a micro-scale. My current work examines the composition and structure of microbial communities that live on seagrass blades and the relationship these communities have with their seagrass host.
