Benthic Invertebrate Community Monitoring and Indicator Development for Barnegat Bay-Little Egg Harbor Estuary

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.

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. -

Table of Contents MOLLUSCA ( GASTROPODA ) Crepidula
MOLLUSCA http://www.mbl.edu/BiologicalBulletin/EGGCOMP/pages/61.html Table of Contents MOLLUSCA ( GASTROPODA ) Crepidula fornicata and C. plana The greenish-brown, boat-shaped C. fornicata adults pile one on top of another to form "chains" of individuals; the colony is attached to a stone, shell or other solid object by the bottom limpet. This species can be collected at Vineyard Haven Harbor, Mass. Another species common to the Woods Hole area, C. plana, is found within whelk or moon snail shells inhabited by large hermit crabs, and can be obtained at Cotuit. This species has a flat, whitish shell and is considerably smaller than C. fornicata. Both species are potentially protandric hermaphrodites. The active males are small, whereas the mature females are the large, older individuals; all sizes and sexual conditions can be found in any colony. C. fornicata breeds from mid-June until mid-August. C. plana has a longer season; it breeds through the first week in September (Bumpus, 1898). Sexual activity is reduced to a minimum at sea water temperatures below 15 to 16û C. (Gould, 1950). A. Care of Adults: These limpets may be kept indefinitely in aquaria or fingerbowls provided with a current of flowing, unfiltered sea water. C. plana will readily attach itself to glass when it is removed from the hermit crab shell. Unless they are already in the adult female phase, these animals eventually differentiate into males and females. B. Procuring Fertilized Ova: The animals can be detached with a heavy knife. If eggs have been deposited, they are found in a transparent capsule, attached to the substrate or to the foot of the female. -

VERMEIJ* Department of Earth and Planetary Science, University of California, Davis, Davis, CA,USA C D Received 19 April 2015; revised 30 June 2016; accepted for publication 30 June 2016 The limpet form – a cap-shaped or slipper-shaped univalved shell – convergently evolved in many gastropod lineages, but questions remain about when, how often, and under which circumstances it originated. Except for some predation-resistant limpets in shallow-water marine environments, limpets are not well adapted to intense competition and predation, leading to the prediction that they originated in refugial habitats where exposure to predators and competitors is low. A survey of fossil and living limpets indicates that the limpet form evolved independently in at least 54 lineages, with particularly frequent origins in early-diverging gastropod clades, as well as in Neritimorpha and Heterobranchia. There are at least 14 origins in freshwater and 10 in the deep sea, E F with known times ranging from the Cambrian to the Neogene. -
Trends in Marine Biological Invasions at Local and Regional Scales: the Northeast Pacific Ocean As a Model System

Biogeographic comparisons of introduced biotas at regional and global scales can clarify trends in source regions, invasion pathways, sink regions, and survey effort. We identify the Northeast Pacific Ocean (NEP; northern California to British Colum- bia) as a model system for analyzing patterns of marine invasion success in cool temperate waters. We review literature and field surveys, documenting 123 introduced invertebrate, algal, fish, and vascular plant species in the NEP. Major invasion pathways were shipping (hull fouling, solid and water ballast; 1500s-present) and shellfish (particularly oysters) and finfish imports (commonest from the 1870s to mid- 1900s). The cumulative number of successful invasions over time increased at linear, quadratic, and exponential rates for different taxa, pathways, and regions within the NEP. Regional analysis of four major NEP estuaries showed that Puget Sound and the contiguous Straits had the most introduced spe- cies, followed by Humboldt Bay, Coos Bay and Willapa Bay. -

UPPER PLEISTOCENE MOLLUSCA FROM POTRERO CANYON, PACIFIC PALISADES, CALIFORNIA BY JAMES W. VALENTINE INTRODUCTION Fossiliferous marine terrace sands of Upper Pleistocene age are exposed near the head of Potrero Canyon, Pacific Palisades, California (figure 1). Tens of thousands of mollusks from this deposit, collected over a period of years by Dr. F. C. Clark, were acquired by the Depart- ment of Geology, University of California, Los Angeles, in January, 1943. The preparation of homesites and other construction in Potrero Canyon has caused removal or burial of the most fossiliferous portions of the terrace sands, so that Clark's original locality is destroyed, and his collection cannot now be duplicated. -
Crepidula Convexa Say, 1822 Discovered in Willapa Bay, WA by Linda Schroeder
Crepidula convexa Say, 1822 discovered in Willapa Bay, WA by Linda Schroeder In May 2015 I was on an expedition to Willapa Bay, WA with Rick Harbo, Bill Merilees and George Holm to look for the introduced species, Petricolaria pholadiformis (Lamarck, 1818) [see Rick Harbo’s article in this edition of the Dredgings on page 3]. We were exploring the beach on the west side of Goose Point at Bay Center, WA. While the others searched the compressed mud for boring species, I wandered the beach looking for other mollusk species. I located some slipper shells attached to dead bivalves. It was immediately apparent they were not our local Crepidula adunca (G.B. Sowerby I, 1825). Rick was able to confirm they were Crepidula convexa Say, 1822. C. convexa is a western Atlantic species, occurring from Nova Scotia to Georgia. It is unknown when they might have been first introduced to the bay, but the likely vector is commercial oyster culture. This is the source of most of the other introduced species in the bay. Previous survey reports for exotics published in 1981, 2000 and 2005 do not mention C. convexa in Willapa Bay. But if it is an isolated population, it would not be hard to overlook. Since they need rocks or shells to attach to, their habitat at this site was very limited. The dead shells were not abundant and rocks of any size were sparse. Most of the living shells here are bivalves living below the substrate. Since it is a mud flat, most of the dead shells were coated with a slime of mud, making the slipper shells hard to spot. -
