Biophysical coupling between turbulence, veliger behavior, and larval supply
… and to investigate how that behavior affects larval supply in a turbulent coastal inlet. Gastropod larvae retract their velums and sink rapidly in strong turbulence. Turbulence-induced sinking would be an adaptive behavior if it resulted in increased larval supply and enhanced settlement in …

Species-specific patterns in bivalve larval supply to a coastal embayment
Larval supply is an important process linking reproductive output to recruitment of benthic marine invertebrates. Few species-specific studies of bivalve larvae have been performed due to the lack of suitable methods for species identification. This thesis focused on applying a method to identify …

Influence of hydrodynamics on the larval supply to hydrothermal vents on the East Pacific Rise
Examination of the scales at which larval supply varies spatially and temporally, and correlation with concurrent physical observations can provide insights into larval transport mechanisms that contribute to structuring marine benthic communities. In order to facilitate field studies, this thesis …

Evaluating eelgrass (Zostera marina) as a juvenile habitat for rockfishes : contributions of site characteristics and larval supply to juvenile abundance
… were measured concurrently. These included supply of settling fish (hereafter “settlers”), biotic and abiotic habitat characteristics. The eelgrass beds that I studied were found to differ significantly in their habitat characteristics, the abundance of settlers arriving to them, as well as …

Early Recruitment of <i>Crassostrea virginica</i> to Restored and Natural Oyster Reefs in the Western Mississippi Sound: Larval Supply and Post-Settlement Success
… recruitment of eastern oyster is vital for resupplying adult populations in the face of habitat loss. Coastal oyster populations are challenged by freshwater input, hypoxia, predation and overfishing. Consequently, substantial efforts have been dedicated toward oyster restoration within the …

Temporal variability and vertical structure in larval abundance : the potential roles of biological and physical processes
… results from variability in planktonic larval supply and from processes occurring during and after larval settlement onto the seafloor. The focus of this thesis is on the temporal and spatial variability in larval supply, the extent to which planktonic larval distributions are determined …

Impacts of the Spotted Spiny Lobster (<i>Panulirus guttatus</i>) on the Long-Spined Sea Urchin (<i>Diadema antillarum</i>) and Patch Reef Communities in the Florida Keys
… levels in the Florida Keys, likely due to low larval supply coupled with predation on juveniles. Lobsters are sea urchin predators in other systems and the spotted spiny lobster (<em>Panulirus guttatus </em>) is abundant on coral reefs in the Florida Keys, where I investigated their role as …

What is driving the range extension of Gibbula umbilicalis (Gastropda, Trochidae) in the eastern English Channel?.
… breeding population resulted in an increase in larval supply, allowing the barrier at the range-limit to be penetrated and new sites seeded. The annual sea temperature increases will have had the same effect on the new arrivals settling in the eastern Channel; recruitment at levels exceeding …

Post-settlement processes and early life history dynamics of zebra mussels (Dreissena polymorpha) in the Hudson River estuary
… of empirical data on young life stages including larval supply, the number of larvae settling and the number of settlers that survive the early benthic period (until they become visible). The study of early life stages of most aquatic species poses inherent challenges. In a coastal marine …

The importance of fine-scale flow processes and food availability in the maintenance of soft-sediment communities
… content, microbial content, stability, food supply, and larval supply. One hypothesis for animal-sediment associations is that settling larvae are transported as passive particles and are sorted into different sedimentary habitats much like sediment grains. To test the hypothesis that …

Influence of resource availability on lifehistory traits in coral-feeding butterflyfishes (Pisces: Chaetodontidae)
Given the highly stochastic nature of larval supply, coral reef fishes often settle in sub-optimal habitats with limited access to prey or other resources. Variation in the availability and quality of resources among different reef habitats is likely to have significant effects on the physiological …
