Modelling dispersal and connectivity of broadcast spawning corals in the Western Indian Ocean
… important to dispersal and connectivity of broadcast corals while identifying regions that act as a source of larvae and those that receive larvae. Because habitat destruction and fragmentation through severe bleaching and mortality threaten coral reef health, projected thermal stress from …

Life history traits and population processes in marine bivalve molluscs
… To predict the potential responses of a broadcast-spawning life history such as that of M. arenaria, I surveyed the literature on a variety of bivalve species. By incorporating information on growth, survival, and reproduction into matrix population models I could evaluate the relative …

COMMUNITY STRUCTURE AND FUNCTIONAL DIVERSITY OF IMPERILED GREAT PLAINS FISHES: IMPLICATIONS FOR CONSERVATION OF TWO ENDANGERED SHINERS (SHARPNOSE SHINER NOTROPIS OXYRHYNCHUS AND SMALLEYE SHINER NOTROPIS BUCCULA) IN THE UPPER BRAZOS RIVER, TEXAS
… the Great Plains of North America where pelagic broadcast spawning fish species are declining due to the loss of the natural flow regime and river fragmentation. Uncovering the abiotic and biotic drivers across spatial and temporal scales influencing fish assemblages across the Great Plains is …

Effects of Bisphenol-A and Styrene on Fertilization and Development of the Purple Sea Urchin (Strongylocentrotus purpuratus)
… few studies have examined their effects on broadcast spawning marine invertebrates, specifically at environmentally relevant concentrations. Purple sea urchins, <em>Strongylocentrotus purpuratus,</em> from the central coast of California, were utilized to examine effects of BPA and styrene …

Comportamento reprodutivo de Mussismilia hispida (Verril, 1902) (Cnidaria, Anthozoa, Scleractinia)
… is a sequential hermaphroditic species with a broadcast-spawning mode of reproduction, and external fertilization and development. Female cells developed prior to male cells, and were first observed in April/89. Size of Stage I oocytes partially immersed into mesogleal layer ranged from 13,04μm …

Investigating the ecological role of sound on coral reefs
… reproductive strategies of both brooding and broadcast spawning. I documented these responses in field (Chapters 2, 3, 4) and laboratory (Chapters 3, 5) settings. I found that coral settlement responses to sound were species-specific and mediated by experimental variables including distance …

Marine invertebrate sperm: assessment of sperm quality using computer-aided sperm analysis
… ecosystems are dominated by a variety of marine broadcast spawners. In this study, five species of marine invertebrates, namely Parechinus angulosus (Echinoidea), Choromytilus meridionalis (Bivalvia), Crassostrea gigas (Bivalvia), Donax serra (Bivalvia) and Haliotis midae (Gastropoda) were …

Evaluating Recruitment Seasonality of Red Abalone (<i>Haliotis Rufescens</i>) to Inform Fisheries Management and Conservation Policy
<p>Recruitment, the addition of new individuals to a population, must be understood to make predictions about population growth of marine invertebrates. Red abalone (<em>Haliotis rufescens</em>) represent a former important commercial fishery in California, and until recently, supported a major …
