Advances in the last few years have increased our understanding of the ecology of reef fish larvae, with a focus on the dispersal of larvae and connectivity between benthic adult populations. The goal of this dissertation is to gain insight into the life history of larval reef fishes. I have used a variety of techniques to investigate the biology and ecology of these animals as it pertains to their dispersal and recruitment to reef populations. I used recruitment monitoring surveys to investigate the occurrence of synchrony (or coherence) in recruitment (Chapter 2). I measured the spatial scale of recruitment coherence to infer larval patch size in the pelagic environment. I used an otolith microchemical assay to determine if larvae recruiting in coherent pulses experienced similar environments during their larval lives, inferring that larval patches were coherent throughout larval development and may have originated from similar source populations (Chapter 3). I used a different otolith microchemistry assay to directly measure the dispersal of larvae between reefs (Chapter 4). I measured the swimming performances of larvae of Caribbean reef fish species and used a specially designed swimming flume to examine the contribution of swimming and drifting to the displacement of larvae in a simulated pelagic environment (Chapters 5 and 6). I discuss the results of these studies in the context of the factors that likely cause variation in dispersal and recruitment. Finally, I suggest how to focus future research on the ecology of reef fish larvae. Co-authorship This thesis was written as a series of manuscripts, and as such, several people have been critical to the development of this thesis. Their contributions have been acknowledged in the form of co-authorships on these papers. In many of the chapters I use the first person plural wording as a form of acknowledgement of the contributions of these co-authors. In all these chapters I was the primary developer of the ideas, analyst of the data and writer of the manuscripts, however, various contributions were made by others, I acknowledge their specific contributions below: Peter Sale: Peter has been important in the development of ideas throughout the thesis, in data analysis and for masterminding the ECONAR project from which all of the data for these chapters was generated. Rebecca Fisher: Rebecca has been important in many aspects to the development of this thesis. She closely advised in the statistical analysis of the recruitment data from chapter 1, she was important in the development of the foundational ideas for chapter 2, she helped in the collection and analysis of the larval swimming data from chapter 4. Brian Fryer: Brian has been important in the general analysis of the otolith chemical data and training a field biologist to use sophisticated machinery (i.e. not made out of PVC). Brian's geochemical expertise was also helpful with the analysis of the otolith chemical data in chapter 2. Camilo Mora: Camilo was a very helpful colleague during his tenure in the Sale lab. From my first day of field work on Camilo helped me to generate ideas about the thesis, and the general direction of my research. We collaborated on chapter 5 of this thesis, and Camilo input his effort (and frustration) in the fieldwork as well as in the analysis and writing of the manuscript. Camilo also helped with the generation of ideas for chapter 1. Camilo was also important in the collection of recruitment data from 2002 through 2003. Paul Chittaro: Paul was very helpful and accommodating helping me to learn how to use the ICP-MS, and teaching me how to polish otoliths. He helped with a lot of the field collections for all chapters and helped with the generation of ideas for chapter 3. Cormac Nolan: Cormac is a colleague whom I worked alongside during the field seasons in 2003, 2004 and 2005. Cormac contributed immensely to the collection and identification of larval reef fishes that were used for experiments in chapter 4. He also helped in the collection of recruitment data and fish samples. Paolo Usseglio: Paolo is a field colleague who helped greatly with the fieldwork for all chapters (except chapter 5) in all years of this study. Paolo also contributed to the data analysis in most chapters, and in chapter 2 particularly. v Dedication This thesis is dedicated to my family for all their love and support.

Environmental Studies The Role of Threespot Damselfish (Stegastes planifrons) as a Keystone Species in a Bahamian Patch Reef. (76 pp.) Director of Thesis: Molly R. Morris Abstract The purpose of this research is to identify the role of the threespot damselfish (Stegastes planifrons) as a keystone species. Measurements from four functional groups (algae, coral, fish, and a combined group of slow and sessile organisms) were made in various territories ranging from zero to three damselfish. Within territories containing damselfish, attack rates from the damselfish were also counted. Measures of both aggressive behavior and density of threespot damselfish were correlated with components of biodiversity in three of the four functional groups, suggesting that damselfish play an important role as a keystone species in this community. While damselfish density and measures of aggression were correlated, in some cases only density was correlated with a functional group, suggesting that damselfish influence their community through mechanisms other than behavior.

    State of research of the Osteichthyes fish related to coral reefs in the Honduran Caribbean with catalogued records Estado del conocimiento de los peces osteíctios asociados a los arrecifes de coral en el Caribe de Honduras, con registros catalogados Anarda Isabel Salgado Ordoñez1, Julio Enrique Mérida Colindres1* & Gustavo Adolfo Cruz1 ABSTRACT Research on Honduran coral reef fish has been isolated and scattered. A list of fish species related to coral reefs was consolidated to establish a compiled database with updated taxonomy. The study was conducted between October 2017 and December 2018. Using primary and secondary sources, all potential species in the Western Atlantic were considered, and their actual presence was confirmed using catalogued records published in peer-reviewed journals that included Honduras. In addition, the specimens kept in the Museum of Natural History of Universidad Nacional Autónoma de Honduras were added. Once the list was consolidated, the taxonomic status of each species was updated based on recent literature. A total of 159 species and 76 genera were registered in 32 families. The family with the most species was Labrisomidae with 27 species (17%). Five families had more than five 5 genera registered, while four 4 were represented by more than 16 species, which is equivalent to 42% genera and 51% species. Gobiidae was represented by 10 genera (13%) and 21 species (13%), of which two 2 were endemic: Tigrigobius rubrigenis and Elacatinus lobeli. In turn, Grammatidae was represented by one endemic species Lipogramma idabeli (1.8%). The species Diodon holocanthus and Sphoeroides testudineus represent the first catalogued records for Honduras.

  • Physical Habitat and Social Conditions Across a Coral Reef Shape Spatial Patterns Of
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by DigitalCommons@CalPoly Physical habitat and social conditions across a coral reef shape spatial patterns of intraspecific behavioral variation in a demersal fish Meagan N. Schrandt, Kristin M. Hardy, Kaitlin M. Johnson & Sean C. Lema Biology and Marine Biology and Center for Marine Science, University of North Carolina Wilmington, Wilmington, NC, USA Keywords Aggression; coral cover; coral reef; distribution; fish; habitat change; habitat complexity; habitat heterogeneity; social behavior; social environment. Abstract As coral reef ecosystems decline in health worldwide, reef-associated fishes are being impacted by changes to their coral reef habitats. While previous studies have shown coral reef structure to affect the demography of reef fishes, changes in reef conditions may also impact the behavior of reef fishes as they cope with altered habitats. In this study, we examined spatial patterns of intraspecific behavioral variation in the bicolor damselfish (Stegastes partitus) across the fringing reefs of Curaçao (Caribbean Sea), and explored how this behavioral variation associated with physical and social conditions on the reef. Principal components analysis (PCA) condensed physical parameters of the reef into principal component 1 (PC1), comprising depth, coral cover (%), rugosity, and average hole size (cm2), and principal component 2 (PC2), which represented the number of holes. PC1, but not PC2, increased spatially across the reef as the habitat transitioned from coral rubble in the shallows to live coral on the reef slope. This transition in reef structure was paralleled by changes in social conditions including decreases in bicolor damselfish density in habitats with higher PC1 values.

  • Survey of Fishes in Deep Water Near Rodney's Rock
    Survey of Fishes in Deep Water Near Rodney’s Rock By: Taylor Cotten, Sadra Daniels, Sarah Null, Beth Smith Texas A&M University Study Abroad Dominica 2005 Dr. Robert Wharton & Dr. Anthony Cognato Abstract: In this study, we surveyed the most abundant fish along a transect line set at a depth of 3.0 to 6.5 meters on the north side of Rodney’s Rock. The five most abundant fishes in the deep water transect were Brown Chromis (Chromis multilineata), Sergeant Major (Abudefduf saxatilis), Bicolor Damselfish (Stegastes partitus), Yellowtail Damselfish (Microspathodon chrysurus), and Bluehead Wrasse (Thalassoma bifasciatum). These species were all much less abundant, with the exception of the Brown Chromis, in the shallow water survey conducted by Hoffman et al. (2005). Introduction: Dominica is a small island located in the Lesser Antilles region of the southern Caribbean. The island thrives on ecotourism, one aspect being its variety of aquatic life. Rodney’s Rock is located on the Caribbean coast of Dominica. The rock hosts various habitats for reef fish such as shallow coral reefs, vertical rock formations, and reefs reaching depths of up to 6.5 meters. The diversity of Rodney’s Rock makes it an ideal location for observing and studying fishes and their habitat preferences. This study examines the relative abundance of fishes on a deep water transect at Rodney’s Rock. Material & Methods: A transect line, 12 meters long and anchored by a weight at each end, was established on the north side of Rodney’s Rock. Depth of the transect line varied from 3.0 to 6.5 meters.

  • Male Parental Care and Female Choice in the Bicolor Damselfish, Stegastes Partitus: Bigger Is Not Always Better
    Anim. Behav., 1991, 41, 747 756 Male parental care and female choice in the bicolor damselfish, Stegastes partitus: bigger is not always better ROLAND A. KNAPP & ROBERT R. WARNER Department of Bhglogical Sciences and Marine Science Institute, University of Californ&, Santa Barbara, CA 93106, U.S.A. (Received 19 April 1990; initial acceptance 14 May 1990; final acceptance 21 September 1990; MS. number A5785) Abstract. Female mate choice and patterns of clutch loss were investigated in a natural population of the bicolor damselfish, Stegastes partitus, in an attempt to link criteria used by females in mate choice with male or territory characteristics that enhance egg survival. Previous studies of mate choice in fish species with paternal care have demonstrated the importance of male size and the brood size defended by males in determining female choice. In the present study, neither male size nor brood size influenced male mating success. Of the measured male and territory characteristics, females chose males solely on the basis of their courtship rate. The lack of a female preference for large males and for males with relatively larger broods appeared to result from the patterns of clutch loss. Egg-hatching success was unrelated to either male size or brood size. Future work will determine whether males with high courtship rates provide superior parental care. Mate choice has long been of interest to evolution- attempted to demonstrate the consequences of ary and behavioural ecologists and has recently female choice to offspring survival and female fit- received a tremendous amount of theoretical and ness. In addition, very few have conducted research empirical support (see reviews by Halliday 1978; of this sort in the field, where eggs are exposed to the Bateson 1983).
