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. -

Received: 7 April 2020; Accepted: 19 May 2020; Published: 23 May 2020 Abstract: The community composition of decapods associated with subtidal tropical seagrass meadows was analyzed in a pristine reef lagoon on the Mexican Caribbean coast in the summer of 1995 and winter of 1998. The macrophyte community was dominated by Thalassia testudinum followed by Syringodium filiforme, with interspersed rhyzophytic macroalgae and large patches of drift algae. In each season, 10 one-min trawls were made with an epibenthic sled (mesh aperture 1 mm) during the day and 10 during the night on each of five sites. In all, 53,211 decapods belonging to 119 species were collected. The most diverse taxa were Brachyura and Caridea, but the most abundant were Caridea and Anomura. Dominance was high, with three species (Latreutes fucorum, Cuapetes americanus, and Thor manningi) accounting for almost 50% of individuals, and 10 species accounting for nearly 90% of individuals. There was great similarity in community composition and ecological indices between seasons, but significantly more individuals and species in night versus day samples. -

Diversity of Norwegian Sea Slugs (Nudibranchia): New Species to Norwegian Coastal Waters and New Data on Distribution of Rare Species
Fauna norvegica 2013 Vol. 32: 45-52. ISSN: 1502-4873 Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species Jussi Evertsen1 and Torkild Bakken1 Evertsen J, Bakken T. 2013. Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species. Fauna norvegica 32: 45-52. A total of 5 nudibranch species are reported from the Norwegian coast for the first time (Doridoxa ingolfiana, Goniodoris castanea, Onchidoris sparsa, Eubranchus rupium and Proctonotus mucro- niferus). In addition 10 species that can be considered rare in Norwegian waters are presented with new information (Lophodoris danielsseni, Onchidoris depressa, Palio nothus, Tritonia griegi, Tritonia lineata, Hero formosa, Janolus cristatus, Cumanotus beaumonti, Berghia norvegica and Calma glau- coides), in some cases with considerable changes to their distribution. These new results present an update to our previous extensive investigation of the nudibranch fauna of the Norwegian coast from 2005, which now totals 87 species. An increase in several new species to the Norwegian fauna and new records of rare species, some with considerable updates, in relatively few years results mainly from sampling effort and contributions by specialists on samples from poorly sampled areas. doi: 10.5324/fn.v31i0.1576.

Lloyd1,*, Anna Metaxas1, Brad deYoung2 1Department of Oceanography, Dalhousie University, Halifax, Nova Scotia, Canada B3H 4R2 2Department of Physics and Physical Oceanography, Memorial University, St. John’s, Newfoundland, Canada A1B 3X7 ABSTRACT: Marine gastropods form a diverse taxonomic group, yet little is known about the factors that affect their larval distribution and abundance. We investigated the larval vertical dis- tribution and abundance of 9 meroplanktonic gastropod taxa (Margarites spp., Crepidula spp., Astyris lunata, Diaphana minuta, Littorinimorpha, Arrhoges occidentalis, Ilyanassa spp., Bittiolum alternatum and Nudibranchia), with similar morphology and swimming abilities, but different adult habitats and life-history strategies. We explored the role of physical (temperature, salinity, density, current velocities) and biological (fluorescence) factors, as well as periodic cycles (lunar phase, tidal state, diel period) in regulating larval vertical distribution. Using a pump, we collected plankton samples at 6 depths (3, 6, 9, 12, 18 and 24 m) at each tidal state, every 2 h over a 36 and a 26 h period, during a spring and neap tide, respectively, in St. George’s Bay, Nova Scotia. Con- currently, we measured temperature, salinity, density, fluorescence (as a proxy for chlorophyll, i.e. phytoplankton density), and current velocity. Larval abundance was most strongly related to tem- perature, except for Littorinimorpha and Crepidula spp., for which it was most strongly related to fluorescence. Margarites spp., A. -
Quinquecirrha (Scyphomedusa)
MARINE ECOLOGY - PROGRESS SERIES Vol. 19: 39-41. 1984 hblished August 30 Mar. Ecol. Prog. Ser. I I Changes in the lower Chesapeake Bay food chain in presence of the sea nettle Chrysaora quinquecirrha (Scyphomedusa) David Feigenbaum and Michael Kelly Department of Oceanography, Old Dominion University, Norfolk, Virginia 23508. USA ABSTUCT: The abundance of 4 levels of the lower Chesapeake Bay food chain (Chlorophyll a, herbivores, ctenophore Mnemiopsis leidyi, and Scyphomedusa Chrysaora quinquecimha) were moni- tored twice weekly at 4 stations from May 10 through Sep 30, 1982 in the Lafayette and Elizabeth Rivers (Virginia). The herbivore standing stock, largely copepods, declined sharply in late May when M. leidyi appeared, but rebounded a month later when C. quinquecirrha medusae reduced the ctenophore population. Despite the additional presence of Aurelia aurita (Scyphomedusa) from Jul onward, herbivore abundance remained at moderate levels until the end of the study period. Phytoplankton abundance fluctuated and may have been responsible for brief periods of food shortage; however, the major periods of low herbivore abundance do not seem to have been kept low by food limitation. M. leidyi made a modest resurgence in late Aug when the C. quinquecin-ha population underwent its seasonal decline. Our data suggest that C. quinquecirrha contributes to the secondary productivity of the lower Chesapeake Bay by controlling M. leidyi during summer. INTRODUCTION quence of the sharp reduction in zooplankton standing stock is oxygen depletion in the depths of the fjord due Coelenterate medusae are gelatinous organisms to decaying phytoplankton and dying medusae which with fast growth rates and high metabolic require- accumulate there. -
South Carolina Department of Natural Resources
FOREWORD Abundant fish and wildlife, unbroken coastal vistas, miles of scenic rivers, swamps and mountains open to exploration, and well-tended forests and fields…these resources enhance the quality of life that makes South Carolina a place people want to call home. We know our state’s natural resources are a primary reason that individuals and businesses choose to locate here. They are drawn to the high quality natural resources that South Carolinians love and appreciate. The quality of our state’s natural resources is no accident. It is the result of hard work and sound stewardship on the part of many citizens and agencies. The 20th century brought many changes to South Carolina; some of these changes had devastating results to the land. However, people rose to the challenge of restoring our resources. Over the past several decades, deer, wood duck and wild turkey populations have been restored, striped bass populations have recovered, the bald eagle has returned and more than half a million acres of wildlife habitat has been conserved. We in South Carolina are particularly proud of our accomplishments as we prepare to celebrate, in 2006, the 100th anniversary of game and fish law enforcement and management by the state of South Carolina. Since its inception, the South Carolina Department of Natural Resources (SCDNR) has undergone several reorganizations and name changes; however, more has changed in this state than the department’s name. According to the US Census Bureau, the South Carolina’s population has almost doubled since 1950 and the majority of our citizens now live in urban areas. -
