Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998

Holden Environmental Scientist I Barbara Goetting Environmental Specialist I Thomas Dix Environmental Scientist II MARCH 2003 1 Environmental Protection Commission of Hillsborough County Richard Garrity, Ph.D. Executive Director Gerold Morrison, Ph.D. Director, Environmental Resources Management Division 2 INTRODUCTION The Environmental Protection Commission of Hillsborough County (EPCHC) has been collecting samples in Middle Tampa Bay 1993 as part of the bay-wide benthic monitoring program developed to (Tampa Bay National Estuary Program 1996). The original objectives of this program were to discern the ―health‖—or ―status‖-- of the bay’s sediments by developing a Benthic Index for Tampa Bay as well as evaluating sediment quality by means of Sediment Quality Assessment Guidelines (SQAGs). The Tampa Bay Estuary Program provided partial support for this monitoring. This report summarizes data collected during 1993-1998 from the Middle Tampa Bay segment of Tampa Bay. 3 METHODS Field Collection and Laboratory Procedures: A total of 127 stations (20 to 24 per year) were sampled during late summer/early fall ―Index Period‖ 1993-1998 (Appendix A). Sample locations were randomly selected from computer- generated coordinates. Benthic samples were collected using a Young grab sampler following the field protocols outlined in Courtney et al. (1993). Laboratory procedures followed the protocols set forth in Courtney et al. (1995). Data Analysis: Species richness, Shannon-Wiener diversity, and Evenness were calculated using PISCES Conservation Ltd.’s (2001) ―Species Diversity and Richness II‖ software. -

Otago Submarine Canyons: Mapping and Macrobenthos
Otago Submarine Canyons: Mapping and Macrobenthos Bryce A. Peebles A thesis submitted in partial fulfilment for the degree of Master of Science at the University of Otago December 2013 ii Abstract Submarine canyons are steep-sided “V’ or “U” shaped valleys that incise continental slopes worldwide. The geophysical and oceanographic features of submarine canyons can produce environmental conditions that cause benthic assemblages to be distinctive and productive compared to those of the adjacent slope; however the assemblages are potentially vulnerable to anthropogenic impacts, including bottom fishing. In order to help inform policy and management, submarine canyons need to be objectively defined topographically and their benthic assemblages characterised. A canyon network occurs off the Otago Peninsula, south-eastern New Zealand, but lack of detailed bathymetric data and adequate benthic sampling has limited study of the canyons. This thesis outlines a method of defining submarine canyon areas and examines epifaunal and infaunal assemblages of the Otago canyons and adjacent slope. Objective definition of the Otago canyon network in the GIS software GRASS along with the steps to use this methodology worldwide are described. Archival count data from 1966-74 on the epifauna are analysed using the PRIMER suite of programs to characterise epifaunal assemblages. Anomurans, polychaetes, asteroids and ascidians make up 70% of the epifaunal canyon assemblage. The epifaunal assemblage is clearly defined by water depth and recognisable from 380 m. Quantitative sampling of infauna in Saunders canyon, Papanui canyon and adjacent slope was carried out to examine infaunal community structure of the canyons and adjacent slope. Infaunal canyon assemblages are dominated by polychaetes, amphipods, ophiuroids, decapods and isopods in canyons, accounting for 75% of collected individuals. -

The Ultrastructure of Spermatozoa and Spermiogenesis in Pyramidellid Gastropods, and Its Systematic Importance John M
HELGOLANDER MEERESUNTERSUCHUNGEN Helgol~inder Meeresunters. 42,303-318 (1988) The ultrastructure of spermatozoa and spermiogenesis in pyramidellid gastropods, and its systematic importance John M. Healy School of Biological Sciences (Zoology, A08), University of Sydney; 2006, New South Wales, Australia ABSTRACT: Ultrastructural observations on spermiogenesis and spermatozoa of selected pyramidellid gastropods (species of Turbonilla, ~gulina, Cingufina and Hinemoa) are presented. During spermatid development, the condensing nucleus becomes initially anterio-posteriorly com- pressed or sometimes cup-shaped. Concurrently, the acrosomal complex attaches to an electron- dense layer at the presumptive anterior pole of the nucleus, while at the opposite (posterior) pole of the nucleus a shallow invagination is formed to accommodate the centriolar derivative. Midpiece formation begins soon after these events have taken place, and involves the following processes: (1) the wrapping of individual mitochondria around the axoneme/coarse fibre complex; (2) later internal metamorphosis resulting in replacement of cristae by paracrystalline layers which envelope the matrix material; and (3) formation of a glycogen-filled helix within the mitochondrial derivative (via a secondary wrapping of mitochondria). Advanced stages of nuclear condensation {elongation, transformation of fibres into lamellae, subsequent compaction) and midpiece formation proceed within a microtubular sheath ('manchette'). Pyramidellid spermatozoa consist of an acrosomal complex (round -
Marine Mollusks from Bougainville and Florida, Solomon Islands
^^ FIELDIANA • ZOOLOGY 3 Published by CHICAGO NATURAL HISTORY MUSEUM Volume 39 October 17, 1958 No. 20 MARINE MOLLUSKS FROM BOUGAINVILLE AND FLORIDA, SOLOMON ISLANDS Alan Solem Assistant Curator, Division of Lower Invertebrates My checklist of the Solomon Island marine and fresh-water mol- lusks (Solem, 1953) was based on a large collection donated to Chicago Natural History Museum by Captain J. M. Ross and sup- plemented by a series of records in the literature. Two small collec- tions of marine shells given to the University of Michigan Museum of Zoology add to our knowledge of the fauna, and the additional data are reported below. I did not communicate with Dr. C. E. Fox, who presented the shells to Captain Ross, until after the checklist had been published. Dr. Fox then informed me that all the shells he gave to Captain Ross were found near Guadalcanal and Malaita Islands. The local- ity "Solomon Islands" cited by me (Solem, 1953) for the Fox col- lection should be restricted to "Guadalcanal and Malaita." Since September, 1952, when my manuscript (Solem, 1953) was submitted, the checklist of Kuroda and Habe (1952), the semi-pop- ular book of Kira (1955), and the ecological study of Demond (1957) have brought to my attention a number of nomenclatural changes affecting the names used by me (Solem, 1953) . These changes in no way alter the taxonomic position of the genera and species—only the names applied to the units. Both below, and in a report on the New Hebridean marine fauna (Solem, in press), a number of nomen- clatural changes are recorded. -

Molluscs from the Miocene Pebas Formation of Peruvian and Colombian Amazonia

Molluscs from the Miocene Pebas Formation of Peruvian and Colombian Amazonia. Scripta Geologica, 133: 19-290, 363 fi gs., 1 table, Leiden, November 2006. Frank P. Wesselingh, Nationaal Natuurhistorisch Museum, Postbus 9517, 2300 RA Leiden, The Nether- lands and Biology Department, University of Turku, Turku SF20014, Finland (wesselingh@naturalis. nnm.nl); Lauri C.

Kadolsky, 66, Heathhurst Road, Sanderstead, South Croydon, Surrey CR2 OBA, England ([email protected]). Key words – Mollusca, systematics, Pebas Formation, Miocene, western Amazonia. The mollusc fauna of the Miocene Pebas Formation of Peruvian and Colombian Amazonia contains at least 158 mollusc species, 73 of which are introduced as new; 13 are described in open nomenclature. Four genera are introduced (the cochliopid genera Feliconcha and Glabertryonia, and the corbulid genera Pachy- rotunda and Concentricavalva) and a nomen novum is introduced for one genus (Longosoma). A neotype is designated for Liosoma glabra Conrad, 1874a. The Pebas fauna is taxonomically dominated by two fami- lies, viz. the Cochliopidae (86 species; 54%) and Corbulidae (23 species; 15%). The fauna can be character- ised as aquatic (155 species; 98%), endemic (114 species; 72%) and extinct (only four species are extant). Many of the families represented by a few species in the Pebas fauna include important ecological groups, such as indicators of marine infl uence (e.g., Nassariidae, one species), terrestrial settings (e.g., Acavidae, one species) and stagnant to marginally agitated freshwaters (e.g., Planorbidae, four species).
