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. -

Comparative Diversity of Anemone-Associated Fishes and Decapod Crustaceans in a Belizean Coral Reef and Seagrass System
Marine Biodiversity (2019) 49:2609–2620 https://doi.org/10.1007/s12526-019-00993-5 ORIGINAL PAPER Comparative diversity of anemone-associated fishes and decapod crustaceans in a Belizean coral reef and seagrass system Rohan M. Brooker1,2 & William E. Feeney3,4 & Tiffany L. Sih5,6 & Maud. C. O. Ferrari7 & Douglas P. Chivers2 Received: 16 April 2019 /Revised: 5 July 2019 /Accepted: 12 July 2019/Published online: 19 August 2019 # Senckenberg Gesellschaft für Naturforschung 2019 Abstract Within tropical coastal habitats such as coral reefs and seagrass meadows, sea anemones (Actiniaria) provide microhabitats for a diverse range of fauna. However, the mechanisms that enable these interactions, and how actiniarian diversity and abundance mediates associate assemblages, remains poorly understood. Here, we compared sea anemone species richness and abundance with that of their associated decapod crustaceans and teleost fishes across adjacent coral reef and seagrass habitats at Carrie Bow Cay, Belize. At least 16 decapod and seven fish species were associated with anemones across both habitats, including several previously undocumented associations. While overall anemone-associate richness did not differ between habitats, seagrass anemones had the greatest mean abundance and diversity of both decapod and fish associates. This suggests that the importance of anemones as microhabitat reflected broader benthic complexity and shelter availability, with species aggregating on sea anemones when access to alternative shelter, such as corals, was limited. Patterns of associate distributions on anemones were also highly structured, in terms of both associate and anemone species, with these patterns likely reflecting a combination of associate specialization, intraspecific competition, and anemone morphology and toxicity. -
Decapoda (Crustacea) of the Gulf of Mexico, with Comments on the Amphionidacea
•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.

Diversity and Abundance of Conspicuous Macrocrustaceans on Coral Reefs Differing in Level of Degradation
Diversity and abundance of conspicuous macrocrustaceans on coral reefs differing in level of degradation Roberto González-Gómez1,2, Patricia Briones-Fourzán1, Lorenzo Álvarez-Filip1 and Enrique Lozano-Álvarez1 1 Instituto de Ciencias del Mar y Limnología, Unidad Académica de Sistemas Arrecifales, Universidad Nacional Autónoma de México, Puerto Morelos, Quintana Roo, Mexico 2 Posgrado en Ciencias del Mar y Limnología, Universidad Nacional Autónoma de México, Mexico, Ciudad de México, Mexico ABSTRACT Coral reefs sustain abundant and diverse macrocrustaceans that perform multiple ecological roles, but coral reefs are undergoing massive degradation that may be driving changes in the species composition and abundance of reef-associated macrocrustaceans. To provide insight into this issue, we used non-destructive visual census techniques to compare the diversity and abundance of conspicuous macrocrustaceans (i.e., those >1 cm and visible without disturbance) between two shallow Caribbean coral reefs similar in size (∼1.5 km in length) and close to each other, but one (``Limones'') characterized by extensive stands of the branching coral Acropora palmata, and the other (``Bonanza'') dominated by macroalgae and relic coral skeletons and rubble (i.e., degraded). We also assessed the structural complexity of each reef and the percent cover of various benthic community components. Given the type of growth of A. palmata, we expected to find a greater structural complexity, a higher cover of live coral, and a lower cover of macroalgae on Limones, -
SHALLOW-WATER CRABS (DECAPODA, BRACHYURA) COLLECTED in the SOUTHERN CARIBBEAN NEAR CARTAGENA, COLOMBIA Rafael Lemaitre
BULLETIN OF MARINE SCIENCE. 31(2): U4-266. 19(1 SHALLOW-WATER CRABS (DECAPODA, BRACHYURA) COLLECTED IN THE SOUTHERN CARIBBEAN NEAR CARTAGENA, COLOMBIA Rafael Lemaitre ABSTRACT During a 1-year period (1976-77) a total of 96 brachyuran crab species were collected from Bahi'a de Cartagena and adjacent areas, on the north coast of Colombia, 54 of which are reported for the first time from the Caribbean coast of Colombia. The first known males of the oxystomatous crab Randallia curacaoensis Rathbun, 1922 are discussed and illustrated. Significant range extensions are reported for: Hepatus gronovii Holthuis, 19S9, Epialius kingsleyi Rathbun, 1923, Libinia ferreirae Brito Capello, 1871 (a Brazilian species), and Pilumtuis lacteus Stimpson, 1871; four species were known to occur as far south as the Virgin Islands or Barbados and therefore had not been reported for any section of the South American mainland; these are: Microphrys intenuptus Rathbun, 1920, Pelia mutica (Gibbes, 1850), Etisus maculatus (Stimpson, 1860), and Micropanope barbadensis (Rathbun, 1921). The zoogeography of the species is discussed. Brachyuran crab species occurring on the Caribbean coast of Colombia, on the northern coast of South America, are known largely from the monographs by Rathbun (1918, 192S, 1930, 1937). The Colombian material reported by Rathbun originated, for the most part, from the expeditions of the U.S. Fish Commission steamer ALBATROSS in 1884. Since that time, several oceanographic expeditions have been undertaken on the Caribbean coast of Colombia that have collected brachyurans; and include RA' VELERO III from the Allan Hancock Foundation in 1939, MA' OREGON of the National Marine Fisheries Services in l%3-65, and RA^ JOHN ELLIOTT PILLSBURY from the University of Miami in 1966-68 (BuUis and Thompson, 1965; Bayer, 1969; Bayer et al., 1970). -

We Revised 2 May 2008 used this molecular phylogeny to evaluate evidence for phylogenetic hypotheses based on larval and Accepted 3 May 2008 adult morphology. Our study supports several relationships predicted from larval morphology. These Available online 11 May 2008 include a monophyletic Oregoniidae family branching close to the base of the tree; a close phylogenetic association among the Epialtidae, Pisidae, Tychidae, and Mithracidae families; and some support for the Keywords: monophyly of the Inachidae and Majidae families. However, not all majoid families were monophyletic in Majoidea our molecular tree, providing weaker support for phylogenetic hypotheses inferred strictly from adult 16S 28S morphology (i.e., monophyly of individual families). This suggests the adult morphological characters tra- COI ditionally used to classify majoids into different families may be subject to convergence.

Emerald Crabs Keep Bubble Algae Under Control
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by NSU Works Emerald crabs keep bubble algae under control wider size range of bubble algae, they may be considered more efficient bio-controllers. While less efficient, smaller crabs may be effective in controlling algae in areas difficult to access, such as crevices. Emerald crabs actively feed on bubble alga Ventricaria ventricosa; they grab bubble alga with the chelae, burst it, and then proceed to eat the cell membrane. As the crab tears the algal cell apart, the cell liquid that contains juvenile cytoplasmatic spheres is released into the water, which might contribute to algal dispersal and consequently algal Reef tanks, public infestation. However, by taking into account that: (1) bubble aquariums and algae juveniles may be removed and eliminated by tank aquaculture facilities filtration, (2) fish are fed few times a day while crabs are are commonly invaded continuous foragers and (3) the greatest amount of food is by pest organisms, such as the glass-anemone (Aiptasia consumed by fish while still in the water column (in this way pallida), the fireworm (Hermodice carunculata) and the inaccessible to crabs), we suggest the bio-control efficiency bubble algae (Valonia spp. and Ventricaria ventricosa).
