While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. -

Benthic Invertebrate Community Monitoring and Indicator Development for Barnegat Bay-Little Egg Harbor Estuary
July 15, 2013 Final Report Project SR12-002: Benthic Invertebrate Community Monitoring and Indicator Development for Barnegat Bay-Little Egg Harbor Estuary Gary L. Taghon, Rutgers University, Project Manager [email protected] Judith P. Grassle, Rutgers University, Co-Manager [email protected] Charlotte M. Fuller, Rutgers University, Co-Manager [email protected] Rosemarie F. Petrecca, Rutgers University, Co-Manager and Quality Assurance Officer [email protected] Patricia Ramey, Senckenberg Research Institute and Natural History Museum, Frankfurt Germany, Co-Manager [email protected] Thomas Belton, NJDEP Project Manager and NJDEP Research Coordinator [email protected] Marc Ferko, NJDEP Quality Assurance Officer [email protected] Bob Schuster, NJDEP Bureau of Marine Water Monitoring [email protected] Introduction The Barnegat Bay ecosystem is potentially under stress from human impacts, which have increased over the past several decades. Benthic macroinvertebrates are commonly included in studies to monitor the effects of human and natural stresses on marine and estuarine ecosystems. There are several reasons for this. Macroinvertebrates (here defined as animals retained on a 0.5-mm mesh sieve) are abundant in most coastal and estuarine sediments, typically on the order of 103 to 104 per meter squared. Benthic communities are typically composed of many taxa from different phyla, and quantitative measures of community diversity (e.g., Rosenberg et al. 2004) and the relative abundance of animals with different feeding behaviors (e.g., Weisberg et al. 1997, Pelletier et al. 2010), can be used to evaluate ecosystem health. Because most benthic invertebrates are sedentary as adults, they function as integrators, over periods of months to years, of the properties of their environment. -

Molecular Phylogeny of Echiuran Worms (Phylum: Annelida) Reveals Evolutionary Pattern of Feeding Mode and Sexual Dimorphism
Molecular Phylogeny of Echiuran Worms (Phylum: Annelida) Reveals Evolutionary Pattern of Feeding Mode and Sexual Dimorphism Ryutaro Goto1,2*, Tomoko Okamoto2, Hiroshi Ishikawa3, Yoichi Hamamura4, Makoto Kato2 1 Department of Marine Ecosystem Dynamics, Atmosphere and Ocean Research Institute, The University of Tokyo, Kashiwa, Chiba, Japan, 2 Graduate School of Human and Environmental Studies, Kyoto University, Kyoto, Japan, 3 Uwajima, Ehime, Japan, 4 Kure, Hiroshima, Japan Abstract The Echiura, or spoon worms, are a group of marine worms, most of which live in burrows in soft sediments. This annelid- like animal group was once considered as a separate phylum because of the absence of segmentation, although recent molecular analyses have placed it within the annelids. In this study, we elucidate the interfamily relationships of echiuran worms and their evolutionary pattern of feeding mode and sexual dimorphism, by performing molecular phylogenetic analyses using four genes (18S, 28S, H3, and COI) of representatives of all extant echiuran families. Our results suggest that Echiura is monophyletic and comprises two unexpected groups: [Echiuridae+Urechidae+Thalassematidae] and [Bone- lliidae+Ikedidae]. This grouping agrees with the presence/absence of marked sexual dimorphism involving dwarf males and the paired/non-paired configuration of the gonoducts (genital sacs). Furthermore, the data supports the sister group relationship of Echiuridae and Urechidae. These two families share the character of having anal chaetae rings around the posterior trunk as a synapomorphy. The analyses also suggest that deposit feeding is a basal feeding mode in echiurans and that filter feeding originated once in the common ancestor of Urechidae. Overall, our results contradict the currently accepted order-level classification, especially in that Echiuroinea is polyphyletic, and provide novel insights into the evolution of echiuran worms. -

Due to high local production, metazoans in reducing of soft-sediment habitats fueled, at least in part, by the sediments in the deep sea are often released from the extreme food oxidation of reduced chemicals. Biological studies at limitation prevalent in the background community (e.g. [3]). deep-sea vents, seeps and organic falls have looked at Instead, chemical toxicity may drive infaunal community macrofaunal taxa, but there has yet to be a systematic comparison of the community-level attributes of sedi- structure.

Thank you for always believing in me. ii ACKNOWLEDGMENTS I would like to thank all of the people who helped me collect the specimens for this study, braving the rocks and the waves in the middle of the night: Leigh Ann Boswell, Shannon Evers, and Steffiny Nelson, you were the hard core tako hunters. I am eternally grateful that you sacrificed your evenings to the octopus gods. Also, thank you to David Harrington (best bucket boy), Bert Tanigutchi, Melanie Hutchinson, Christine Ambrosino, Mark Royer, Chelsea Szydlowski, Ily Iglesias, Katherine Livins, James Wood, Seth Ylitalo-Ward, Jessica Watts, and Steven Zubler. This dissertation would not have happened without the support of my wonderful advisor, Dr. Les Watling. Even though I know he wanted me to study a different kind of “octo” (octocoral), I am so thankful he let me follow my foolish passion for cephalopod sexual selection. Also, he provided me with the opportunity to ride in a submersible, which was one of the most magical moments of my graduate career. -
ABSTRACT Title of Dissertation: PATTERNS IN
ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range. -

HAUCK Department of Earth and Atmospheric Sciences, University of Alberta, 1-26 Earth Sciences Building, Edmonton, Alberta, Canada, T6G 2E3, Email: [email protected] SHAHIN E.

GINGRAS Department of Earth and Atmospheric Sciences, University of Alberta, 1-26 Earth Sciences Building, Edmonton, Alberta, Canada, T6G 2E3 RRH: RESOURCE DISTRIBUTION CONTROLS ON FODICHNIA MORPHOLOGY LRH: HAUCK ET AL. Keywords: Organic carbon, Chiridotea caeca, Pascichnia, Intertidal, Neoichnology, Bioturbation 1 ABSTRACT Grazing trackways of the Valviferan isopod Chiridotea caeca are examined to establish relationships between trackway complexity and morphology, and the distribution of food (organic carbon). These isopods burrow up to 1 cm beneath the surface within ripple troughs and plane-bedded sand of the upper intertidal zone. The burrows are grouped into three forms based on trackway complexity and the degree of looping and trackway crossover in planview. Sediment samples taken directly from the furrows of the trails are used to establish the total organic-carbon content associated with each type of burrow morphology. There is an increase in organic-carbon content from burrows of low complexity (linear), to burrows of high complexity (convolute with many crossovers), suggesting that benthic food content directly influences the behavior of C. caeca, which is manifest in the trackway morphology. Detailed study of trackway architecture further reveals a relationship between C. caeca and food content leading to the recognition of three grazing styles, which are directly associated with the plan-view morphology of the trackway.
