Diets and Coexistence of the Sea Urchins Lytechinus Variegatus and Arbacia Punctulata (Echinodermata) Along the Central Florida Gulf Coast
MARINE ECOLOGY PROGRESS SERIES Vol. 295: 171–182, 2005 Published June 23 Mar Ecol Prog Ser Diets and coexistence of the sea urchins Lytechinus variegatus and Arbacia punctulata (Echinodermata) along the central Florida gulf coast Janessa Cobb, John M. Lawrence* Department of Biology, University of South Florida, Tampa, Florida 33620, USA ABSTRACT: The basis for coexistence of similar species is fundamental in community ecology. One mechanism for coexistence is differentiation of diets. Lytechinus variegatus and Arbacia punctulata coexist in different microhabitats along the Florida gulf coast. Their great difference in morphology might affect their choice of microhabitats and diet. We analyzed diets of both species at 1 offshore and 1 nearshore site where both occurred in relatively equal numbers, an offshore site dominated by A. punctulata and an offshore site dominated by L. variegatus. Gut contents were analyzed to deter- mine the diet. A. punctulata prim. consumed sessile invertebrates except on dates when algal avail- ability was higher than normal. L. variegatus primarily consumed macroflora except on dates when macroflora was extremely limited. Electivity indices revealed no strong preferences for particular species of algae, although L. variegatus consumed many drift species. A. punctulata and L. variega- tus both fed in a random manner, although they avoided particular species of algae known to contain high concentrations of secondary metabolites. The diet of A. punctulata was correlated with algae only over rubble outcroppings at the offshore site with the highest biomass. Diets of offshore popula- tions were more similar to each other, regardless of the presence of conspecifics, than to those of populations at Caspersen Beach (nearshore site). -

Aceptado 17-IX-2008. Abstract: Regular sea urchins substrate association (Echinodermata: Echinoidea) on Isla Verde lagoon reef, Veracruz, Mexico. The diversity, abundance, distribution and substrate association of the regular sea urchins found at the South part of Isla Verde lagoon reef, Veracruz, Mexico is presented. Four field sampling trips where made between October, 2000 and October, 2002. One sampling quadrant (23 716 m2) the more representative, where selected in the southwest zone of the lagoon reef, but other sampling sites where choose in order to cover the south part of the reef lagoon. The species found were: Eucidaris tribuloides tribuloides, Diadema antillarum, Centrostephanus longispinus rubicingulus, Echinometra lucunter lucunter, Echinometra viridis, Lytechinus variegatus and Tripneustes ventricosus. The relation analysis between the density of the echi- noids species found in the study area and the type of substrate was made using the Canonical Correspondence Analysis (CCA). The substrates types considerate in the analysis where: coral-rocks, rocks, rocks-sand, and sand and Thalassia testudinum. -

Steller Moss Landing Marine Laboratories Dr. Michael H. Graham Moss Landing Marine Laboratories Dr. Scott L. Hamilton Moss Landing Marine Laboratories ABSTRACT COMMUNITY STRUCTURE AND ENERGY FLOW WITHIN RHODOLITH HABITATS AT SANTA CATALINA ISLAND, CA by Scott Stanley Gabara The purpose of this study was to describe the floral and faunal community associated with rhodolith beds, which are aggregations of free-living coralline algal nodules, off of Santa Catalina Island. Surveys of macroalgal cover, infaunal and epifaunal invertebrates, and fishes suggest rhodolith beds off Santa Catalina Island support greater floral and faunal abundances than adjacent sand habitat. Community separation between rhodolith and sand habitats was due to increased presence of fleshy macroalgae, herbivorous gastropods, and greater abundance of infaunal invertebrates dominated by amphipods, mainly tanaids and gammarids. Stable isotopes were used to determine important sources of primary production supporting rhodolith beds and to identify the major pathways of energy. Stable isotopes suggest the rhodolith bed food web is detrital based with contributions from water column particulate organic matter, drift kelp tissue, and kelp particulates from adjacent kelp beds. -

Editor: Julian Marchesi ABSTRACT In this paper, we describe the microbial composition and their predictive metabolic profile in the sea urchin Lytechinus variegatus gut ecosystem along with samples from its habitat by using NextGen amplicon sequencing and downstream bioinformatics analyses. The microbial communities of the gut tissue revealed a near-exclusive abundance of Campylobacteraceae, whereas the pharynx tissue consisted of Tenericutes, followed by Gamma-, Alpha- and Epsilonproteobacteria at approximately equal capacities. -

Instituto de Recursos, Universidad del Mar (UMAR), Campus Puerto Ángel, Distrito de San Pedro Pochutla, Puerto Ángel, Oaxaca, México.C.P. 70902; [email protected], [email protected] Received 09-VI-2014. Corrected 14-X-2014. Accepted 17-XII-2014. Abstract: Diadema mexicanum, a conspicuous inhabitant along the Mexican Pacific coast, is a key species for the dynamics of coral reefs; nevertheless, studies on population dynamics for this species are scarce. Monthly sampling was carried out between April 2008 and March 2009 at Isla Montosa and La Entrega, Oaxaca, Mexico using belt transects. Population density was estimated as well as abundance using Zippin’s model. The relation- ship of density with sea-bottom temperature, salinity, pH, and pluvial precipitation was analyzed using a step by step multiple regression analysis. Spatial distribution was analyzed using Morisita’s, Poisson and negative binomial models. Natural mortality rate was calculated using modified Berry’s model. Mean density was 3.4 ± 0.66 ind·m-2 in La Entrega and 1.2 ± 0.4 ind·m-2 in Isla Montosa. Abundance of D. mexicanum in La Entrega was 12166 ± 25 individuals and 2675 ± 33 individuals in Isla Montosa. In Isla Montosa there was a positive relationship of density with salinity and negative with sea-bottom temperature, whereas in La Entrega there was not a significant relationship of density with any recorded environmental variable. -
