La carapace est presque carrée, légèrement convexe, avec des stries latérales. Le front présente un sinus médian profond. Les chélipèdes sont faiblement granuleux. Les pattes sont relativement longues et fines. L'abdomen du mâle est triangulaire, celui de la femelle arrondi. La largeur de la carapace atteint 2,7 cm. La couleur est gris brun avec de très petites taches claires ; la face ventrale est presque blanche. Les larves sont émises par les femelles dans les rivières et ces larves gagnent la mer pour y poursuivre leur développement qui dure 17 jours. Ce crabe a une activité crépusculaire et nocturne. Il creuse des galeries où il se réfugie le jour. Il se nourrit de matières organiques en décomposition. Il est la proie des oiseaux. On le rencontre dans les mangroves et parmi la végétation des berges des cours d'eau jusqu'à 9 km de la mer et 300 m d'altitude. L'espèce est endémique de l'arc antillais. Figure 1.

The central objective of this study was to analyze seasonal variations in site fdelity in C. guanhumi, a species that is intensively exploited in Brazil, in spite of being part of the Ofcial National List of Critically Endangered Species. This species currently sufers multiple severe threats, such as overharvesting and habitat destruction. C. guanhumi were sampled monthly at four fxed sectors that were delim‑ ited at the upper fringe of a restricted-access mangrove at Itamaracá Island between April 2015 and March 2016. One thousand and seventy-eight individuals were captured, measured, sexed, weighed, and their color patterns registered. Of these, 291 individuals were tagged with PIT (Passive Integrated Transponder) tags. Ninety-seven individuals (size range 27.0–62.6 mm carapace width) were successfully recaptured, totaling 135 recapture events. The largest interval between marking and recapture was 331 days. Through the use of mark-recapture-based models, it was possible to 2 estimate the local population as being 1312 ( 417) individuals (mean density 2.23 0.71 ind. m­ − ). Considering the mean density of burrow openings and individuals,± there were 3.4 burrow openings± per individual.

    •59 Decapoda (Crustacea) of the Gulf of Mexico, with Comments on the Amphionidacea Darryl L. Felder, Fernando Álvarez, Joseph W. Goy, and Rafael Lemaitre The decapod crustaceans are primarily marine in terms of abundance and diversity, although they include a variety of well- known freshwater and even some semiterrestrial forms. Some species move between marine and freshwater environments, and large populations thrive in oligohaline estuaries of the Gulf of Mexico (GMx). Yet the group also ranges in abundance onto continental shelves, slopes, and even the deepest basin floors in this and other ocean envi- ronments. Especially diverse are the decapod crustacean assemblages of tropical shallow waters, including those of seagrass beds, shell or rubble substrates, and hard sub- strates such as coral reefs. They may live burrowed within varied substrates, wander over the surfaces, or live in some Decapoda. After Faxon 1895. special association with diverse bottom features and host biota.

    Regulation of community structure: top-down effects are modified by omnivory, nutrients, stress, and habitat complexity An Abstract of a Dissertation Presented to The Faculty of the Department of Computer Science University of Houston In Partial Fulfillment Of the Requirements for the Degree Doctor of Philosophy By Juan Manuel Jiménez Martínez May 2008 1 Abstract Biological communities are structured by a complex set of processes that have hindered the development of a general theory of community structure regulation. Current ideas and hypotheses have largely ignored the presence of interactions among the factors that regulate community structure. In this thesis I focused explicitly on the interactions among omnivory, nutrient availability, salinity stress levels, and habitat complexity. I examined these interactions using a combination of mesocosm and field factorial experiments in which I manipulated the levels of nutrients, salinity stress, and the presence (or absence) of top omnivores and common herbivores. These experiments demonstrated that, (1), nutrient addition increases the strength of top-down forces, but the effects of salinity stress are variable and species dependent, and (2), decreasing habitat complexity increases the strength of top-down forces and trophic cascades. In sum, my results suggest that the inherent complexity of natural communities and the interactions among the forces structuring them can lead to many different experimental outcomes that reflect the many ways in which species interactions are affected by environmental variables to alter the structure of these communities. Progress in understanding community structure will come from experiments that probe these interactive processes and seek to identify commonalities in responses based on consumer behavior, plant traits or habitat type.

    EFFECTS OF LOCAL ADAPTATION ON INVASION SUCCESS: A CASE STUDY OF Rhithropanopeus harrisii (GOULD) A Dissertation by TERRENCE MICHAEL BOYLE JR Submitted to the Office of Graduate Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Mary Wicksten Committee Members, Gil Rosenthal Duncan MacKenzie Luis Hurtado Head of Department, U.J. McMahan August 2013 Major Subject: Zoology Copyright 2013 Terrence Michael Boyle Jr ABSTRACT A major trend in invasion biology is the development of models to accurately predict and define invasive species and the stages of their invasions. These models focus on a given species with an assumed set of traits. By doing so, they fail to consider the potential for differential success among different source populations. This study looked at the inland invasion of Rhithropanopeus harrisii in the context of a current invasion model. This species has been introduced worldwide, but has only invaded freshwater reservoirs within the state of Texas (United States) indicating a potential difference amongst source populations. Previous studies indicate that this species should not be capable of invading inland reservoirs due to physiological constraints in the larvae. A more recent study gives evidence to the contrary. To investigate whether the inland populations are in fact successfully established, I attempted to answer the following questions: Can inland populations successfully reproduce in the inland reservoirs and rivers? If so, what factors in the native environment could have led to the evolution of this ability? What are the impacts of this species in the inland reservoirs and what is its potential spread? I combined a larval developmental study, conspecific and heterospecific crab competition trials, field collections, gut content analysis, shelter competition trials with crayfish, and larval and adult dispersal study to answer these questions.

  • Annotated Checklist of Decapod Crustaceans of Atlantic Coastal and Continental Shelf Waters of the United States
    PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON 116(1):96—157. 2003. Annotated checklist of decapod crustaceans of Atlantic coastal and continental shelf waters of the United States Martha S. Nizinski National Marine Fisheries Service National Systematics Laboratory, Smithsonian Institution, P.O. Box 37012, NHB, MRC-0153, Washington, D.C. 20013-7012, U.S.A., e-mail: [email protected] Abstract.—The decapod crustacean assemblage inhabiting estuarine, neritic and continental shelf waters (to 190 m) of the temperate eastern United States is diverse, with 391 species reported from Maine to Cape Canaveral, Florida. Three recognized biogeographic provinces (Boreal in part, Virginian and Car- olinian) are included in this region. The assemblage contains 122 shrimp spe- cies (28 penaeids, 2 stenopodids, and 92 carideans), 10 thalassinideans, 8 lob- sters, 61 anomurans and 190 brachyurans. Since previous compilation of this fauna, 12 additional species have been described, including four carideans, one callianassid, four anomurans, and three brachyurans. Range extensions into the region have been reported for another five species (Parapenaeus americanus, Scyllarides aequinoctialis, Petrolisthes armatus, Dromia erythropus, Clythro- cerus nitidus). One species, Hemigrapsus sanguineus, has been introduced and become established throughout intertidal environments from southern Maine to northern North Carolina. Six species previously recorded from this region are no longer considered to occur there. Two of these species occur south of the Carolinian biogeographic province, three others are now known to occur only in the Pacific Ocean, and one species previously considered as likely to occur in the region has never actually been recorded there. Scientific nomenclature for all species recorded from the region is updated and referenced.
