Anchialine Cave Biology in the Era of Speleogenomics Jorge L
International Journal of Speleology 45 (2) 149-170 Tampa, FL (USA) May 2016 Available online at scholarcommons.usf.edu/ijs International Journal of Speleology Off icial Journal of Union Internationale de Spéléologie Life in the Underworld: Anchialine cave biology in the era of speleogenomics Jorge L. Pérez-Moreno1*, Thomas M. Iliffe2, and Heather D. Bracken-Grissom1 1Department of Biological Sciences, Florida International University, Biscayne Bay Campus, North Miami FL 33181, USA 2Department of Marine Biology, Texas A&M University at Galveston, Galveston, TX 77553, USA Abstract: Anchialine caves contain haline bodies of water with underground connections to the ocean and limited exposure to open air. Despite being found on islands and peninsular coastlines around the world, the isolation of anchialine systems has facilitated the evolution of high levels of endemism among their inhabitants. The unique characteristics of anchialine caves and of their predominantly crustacean biodiversity nominate them as particularly interesting study subjects for evolutionary biology. However, there is presently a distinct scarcity of modern molecular methods being employed in the study of anchialine cave ecosystems. The use of current and emerging molecular techniques, e.g., next-generation sequencing (NGS), bestows an exceptional opportunity to answer a variety of long-standing questions pertaining to the realms of speciation, biogeography, population genetics, and evolution, as well as the emergence of extraordinary morphological and physiological adaptations to these unique environments. The integration of NGS methodologies with traditional taxonomic and ecological methods will help elucidate the unique characteristics and evolutionary history of anchialine cave fauna, and thus the significance of their conservation in face of current and future anthropogenic threats. -
Polychaetes Associated with a Tropical Ocean Outfall: Synthesis of a Biomonitoring Program Off O'ahu, Hawai'f
Polychaetes Associated with a Tropical Ocean Outfall: Synthesis ofa Biomonitoring Program off O'ahu, Hawai'F J. H. Bailey-Brock,2,3,4,5 B. Paavo,3,4 B. M. Barrett,3,4 and J. Dreyer3,4 Abstract: A comparison of benthic polychaete communities off the Sand Island Wastewater Outfall was undertaken to recognize organic enrichment indicator species for Hawaiian waters. Primary-treatment sewage is discharged off the south shore of O'ahu at 70 m depth. A historical data set spanning 9 yr for seven sites at 70 m and two recent studies at 20, 50, and 100 m depths were analyzed. Geochemical data did not support the assumption that the outfall is an im portant source of organic enrichment in nutrient-poor sandy sediments within oligotrophic tropical waters. Five polychaete species, however, appeared partic ularly sensitive, positively or negatively, to environmental conditions near the outfall. Neanthes arenaceodentata (Nereididae) and Ophryotrocha adherens (Dor villeidae) have been dominant at sites within the outfall's zone of initial dilution (ZID). Since 1993, N arenaceodentata has virtually disappeared, and 0. adherens concurrently became abundant and continued to flourish at ZID sites. Well known indicators within the Capitella capitata complex (Capitellidae) were pres ent at ZID and control (far field) sites though their ZID abundance was greater. Two sabellids, Euchone sp. Band Augeneriella dubia were inversely distributed, the smaller Euchone sp. B at far field sites and larger A. dubia within ZID sta tions. The former was most likely restricted to a greater proportion offine sed iment particles at two far field sites. -
Towards Understanding the Phylogenetic History of Hydrozoa: Hypothesis Testing with 18S Gene Sequence Data*
SCI. MAR., 64 (Supl. 1): 5-22 SCIENTIA MARINA 2000 TRENDS IN HYDROZOAN BIOLOGY - IV. C.E. MILLS, F. BOERO, A. MIGOTTO and J.M. GILI (eds.) Towards understanding the phylogenetic history of Hydrozoa: Hypothesis testing with 18S gene sequence data* A. G. COLLINS Department of Integrative Biology and Museum of Paleontology, University of California, Berkeley, CA 94720, USA SUMMARY: Although systematic treatments of Hydrozoa have been notoriously difficult, a great deal of useful informa- tion on morphologies and life histories has steadily accumulated. From the assimilation of this information, numerous hypotheses of the phylogenetic relationships of the major groups of Hydrozoa have been offered. Here I evaluate these hypotheses using the complete sequence of the 18S gene for 35 hydrozoan species. New 18S sequences for 31 hydrozoans, 6 scyphozoans, one cubozoan, and one anthozoan are reported. Parsimony analyses of two datasets that include the new 18S sequences are used to assess the relative strengths and weaknesses of a list of phylogenetic hypotheses that deal with Hydro- zoa. Alternative measures of tree optimality, minimum evolution and maximum likelihood, are used to evaluate the relia- bility of the parsimony analyses. Hydrozoa appears to be composed of two clades, herein called Trachylina and Hydroidolina. Trachylina consists of Limnomedusae, Narcomedusae, and Trachymedusae. Narcomedusae is not likely to be the basal group of Trachylina, but is instead derived directly from within Trachymedusae. This implies the secondary gain of a polyp stage. Hydroidolina consists of Capitata, Filifera, Hydridae, Leptomedusae, and Siphonophora. “Anthomedusae” may not form a monophyletic grouping. However, the relationships among the hydroidolinan groups are difficult to resolve with the present set of data. -

SCI. MAR., 63 (Supl. 1): 261-274 SCIENTIA MARINA 1999 MAGELLAN-ANTARCTIC: ECOSYSTEMS THAT DRIFTED APART. W.E. ARNTZ and C. RÍOS (eds.) On the origin and evolution of Antarctic Peracarida (Crustacea, Malacostraca)* ANGELIKA BRANDT Zoological Institute and Zoological Museum, Martin-Luther-King-Platz 3, D-20146 Hamburg, Germany Dedicated to Jürgen Sieg, who silently died in 1996. He inspired this research with his important account of the zoogeography of the Antarctic Tanaidacea. SUMMARY: The early separation of Gondwana and the subsequent isolation of Antarctica caused a long evolutionary his- tory of its fauna. Both, long environmental stability over millions of years and habitat heterogeneity, due to an abundance of sessile suspension feeders on the continental shelf, favoured evolutionary processes of “preadapted“ taxa, like for exam- ple the Peracarida. This taxon performs brood protection and this might be one of the most important reasons why it is very successful (i.e. abundant and diverse) in most terrestrial and aquatic environments, with some species even occupying deserts. The extinction of many decapod crustaceans in the Cenozoic might have allowed the Peracarida to find and use free ecological niches. Therefore the palaeogeographic, palaeoclimatologic, and palaeo-hydrographic changes since the Palaeocene (at least since about 60 Ma ago) and the evolutionary success of some peracarid taxa (e.g. Amphipoda, Isopo- da) led to the evolution of many endemic species in the Antarctic. Based on a phylogenetic analysis of the Antarctic Tanaidacea, Sieg (1988) demonstrated that the tanaid fauna of the Antarctic is mainly represented by phylogenetically younger taxa, and data from other crustacean taxa led Sieg (1988) to conclude that the recent Antarctic crustacean fauna must be comparatively young. -

BAMBER ARTOO Marine Biology Consultants, Ocean Quay Marina, Belvidere Road, Southampton SO14 5QY, United Kingdom. E-mail: [email protected] Abstract Apseudomorph tanaidaceans from recent samples of the South China Sea benthos off Brunei have been examined. The habitats were sandy substrata from between 5 and 90 m depth. Fourteen species of the four families considered here were discovered. A new species of Tanapseudes is described. The distribution of Phoxokalliapseudes gobinae is analyzed. Biropalostoma goofi is recorded for the first time in Brunei waters. One new species of the Apseudidae (in the genus Bunakenia) and four new species of the Parapseudidae (one each in the genera Platylicoa and Pakistanapeudes, and two in a new genus Actenos, of the subfamily Pakistanapseudinae) are described. The genus Platylicoa is moved to the Pakistanapseudinae, and the genus Hainanius is returned to the Parapseudidae (Parapseudinae). Apseudes tenuicorporeus is moved from Biropalostoma to the new pakistanapseudin genus described herein.

Pinto, Débora P. D. Santos & Fernando D’Incao Fundação Universidade Federal do Rio Grande, Caixa Postal 474, 96201-900 Rio Grande, RS, Brasil. ([email protected], [email protected], [email protected], [email protected]) ABSTRACT. Natural diet of the blue crab Callinectes sapidus (Decapoda, Portunidae) in the Patos Lagoon estuary area, Rio Grande, Rio Grande do Sul, Brazil. The Southern Brazil blue crab Callinectes sapidus Rathbun, 1869 is the most abundant crab of the genus Callinectes in Patos Lagoon estuary. Although this species is widely distributed throughout the Patos Lagoon estuary area, there is little information about its natural diet. This species is an important predator and has a significant influence on its prey populations. The aim of this study was to check the natural diet of blue crab through the foregut contents analysis. Crabs were collected using an otter trawl net from March 2003 to March 2004. After collected, crabs were preserved immediately in 10% formaldehyde. The carapace width, weight and sex were measured for each individual. The foregut of each crab was removed and stored in 70% ethanol. Blue crab feeds on a wide variety of sessile and slow moving invertebrates. The main item was Detritus, followed by the suspension-feeder mollusk Erodona mactroides Bosc, 1802 (Erodonidae). Sand grains and the small crustaceans of class Ostracoda, were an important component of the foregut contents, but sand grains were not considered food. -

In addition, monophyly of most or all capitellid genera was questionable, as some diagnostic characters vary ontogenetically within individuals. We tested the monophyly of Capitellidae and eight capitellid genera using phyloge- netic analyses of combined 18S, 28S, H3, and COI gene sequences from 36 putative capitellid spe- cies. In our trees, Capitellidae formed a monophyletic sister group to Echiura, and Capitella was also monophyletic, separated by a long branch from other capitellids. Well-supported clades each containing representatives of different genera, or containing a subset of species within a genus, indicated that Barantolla, Heteromastus, and Notomastus are likely not monophyletic. We mapped three morphological characters traditionally used to define capitellid genera (head width relative to width of first segment, number of thoracic segments, and number of segments with capillary chae- tae) onto our tree. -
ABSTRACT Title of Dissertation: PATTERNS IN
ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range.
