The crabs were obtained from Ubatuba region north-eastern shore of São Paulo State. In the laboratory, all the individuals were dissected, the stomach was retreated and fixed in 10% formaline. The alimentary items were identified under stereomicroscope and analysed by the method of Frequency of Occurrence. A total of 194 stomachs was analysed and nine alimentary items were obtained. Unindentified material was found in 98% of analysed stomach and poriferan were present in less then 1% of stomachs. These results pointed a diversified diet explored by this crab, as well as the employment of some different methods for food intake. This suggested that these crabs could occupy different position in the trophic chain. Key words: Stomach contents, alimentary itens, spider crab INTRODUCTION Gouvêa, 1998). -

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. -
Reduced Mobility Is Associated with Compensatory Feeding and Increased Diet Breadth of Marine Crabs
MARINE ECOLOGY PROGRESS SERIES Published November 3 Mar Ecol Prog Ser Reduced mobility is associated with compensatory feeding and increased diet breadth of marine crabs John J. Stachowicz*,Mark Hay8* University of North Carolina at Chapel Hill, Institute of Marine Sciences. Morehead City, North Carolina 28557. USA ABSTRACT: Direct effects of predation have been widely recognized as important in affecting prey population dynamics and evolution. However, less attention has been devoted to the consequences of indirect effects of predators on prey behavior. For example, to avoid predation many animals restrict their activities to physical refugia and adopt low-mobility Mestyles, yet the consequences of these anti- predator behaviors for foraging and diet selection are relatively unknown. In this study we examine the relationships between mobility, feeding preferences, and compensatory feeding for 3 species of marine decapod crabs feeding on seaweeds in North Carolina, USA. Low mobility and high site fidellty of crabs were associated with a broad, non-selective diet and compensatory feeding. The majid Mithrax forceps exhibited the lowest mobility, highest site fidelity, and least selective diet of the 3 species, whereas another majid Libinia dubia was intermehate in both rnobllity and selectivity, and the xanthid Panopeus herbstii had the greatest mobility and narrowest diet. Of these 3 crabs, only M. forceps com- pensated for low food quality by increasing consumption rates in single food-species feeding assays. This may be because M. forceps is resistant to (or tolerant of) seaweed chemical defenses, while other crab species are not. The ability to consume, and presumably subsist on, a wide variety of potential foods including those defended from more mobile consumers may facilitate a low-mobllity lifestyle, allowing the crab to minimize movement and reduce exposure to predators. -

E : [email protected] Abstract An advantageous property of mesh-based geometric morphometrics (GM) towards landmark-based approaches, is the possibility of precisely eXamining highly irregular shapes and highly topographic surfaces. In case of spherical-harmonics-based GM the main requirement is a completely closed mesh surface, which often is not given, especially when dealing with natural objects. Here we present a methodological workflow to prepare 3D segmentations containing large cavity openings for the conduction of spherical-harmonics-based GM. -

LARVAL DEVELOPMENT OF THE SPIDER CRAB, LIBINIA EMARGINATA (MAJIDAE)l D. MICHAEL JOHNS2 AND WILLIAM H. LANG3 ABSTRACT Larval development ofthe spider crab, Libinia emarginata, consists oftwo zoeal stages and megalopa. Laboratory-reared larvae (South Carolina and Rhode Island) are described and compared with planktonic larvae from Narragansett Bay, R.I. No significant variations in morphology were found between laboratory-cultured larvae and "wild" larvae from plankton catches; first stage zoea from South Carolina were smaller than Rhode Island specimens. Using Artemia diets, the best percentage survival in culture was found to be 20°C for Rhode Island larvae and 25°C for South Carolina larvae. Zoeal stages show little difference from larvae ofL. dubia; however, the megalopae ofthe two species can be differentiated by the number of protuberances on the cardiac region of the carapace. Larval stages have previously been described for a ters and development times. Characteristics number of species from the family Majidae (San which distinguish L. emarginata larvae from the difer and Van Engel 1971, 1972). For the genus larvae ofL. dubia andL. erinacea were also noted. Libinia only two complete descriptions have been published. Boschi and Scelzo (1968) described lar METHODS AND MATERIALS val stages ofL. spinosa from Mar del Plata Harbor, Argentina; and Sandifer and Van Engel (1971) Ovigerous females of L. emarginata were col described the larval stages of L. dubia from lected off Charleston, S.C., during fall 1975 and Chesapeake Bay. Larvae ofL. erinacea have been spring1976, and in Narragansett Bay, R.I., during described by Yang (1967), but the results remain summer 1976. -

Larval Growth
LARVAL GROWTH Edited by ADRIAN M.WENNER University of California, Santa Barbara OFFPRINT A.A.BALKEMA/ROTTERDAM/BOSTON DARRYL L.FELDER* / JOEL W.MARTIN** / JOSEPH W.GOY* * Department of Biology, University of Louisiana, Lafayette, USA ** Department of Biological Science, Florida State University, Tallahassee, USA PATTERNS IN EARLY POSTLARVAL DEVELOPMENT OF DECAPODS ABSTRACT Early postlarval stages may differ from larval and adult phases of the life cycle in such characteristics as body size, morphology, molting frequency, growth rate, nutrient require ments, behavior, and habitat. Primarily by way of recent studies, information on these quaUties in early postlarvae has begun to accrue, information which has not been previously summarized. The change in form (metamorphosis) that occurs between larval and postlarval life is pronounced in some decapod groups but subtle in others. However, in almost all the Deca- poda, some ontogenetic changes in locomotion, feeding, and habitat coincide with meta morphosis and early postlarval growth. The postmetamorphic (first postlarval) stage, here in termed the decapodid, is often a particularly modified transitional stage; terms such as glaucothoe, puerulus, and megalopa have been applied to it. The postlarval stages that fol low the decapodid successively approach more closely the adult form. Morphogenesis of skeletal and other superficial features is particularly apparent at each molt, but histogenesis and organogenesis in early postlarvae is appreciable within intermolt periods. Except for the development of primary and secondary sexual organs, postmetamorphic change in internal anatomy is most pronounced in the first several postlarval instars, with the degree of anatomical reorganization and development decreasing in each of the later juvenile molts. -
