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. -

Juvenile Sphaeroma Quadridentatum Invading Female-Oœspring Groups of Sphaeroma Terebrans
Journal of Natural History, 2000, 34, 737–745 Juvenile Sphaeroma quadridentatum invading female-oŒspring groups of Sphaeroma terebrans MARTIN THIEL1 Smithsonian Marine Station, 5612 Old Dixie Highway, Fort Pierce, Fla 34946, USA (Accepted: 6 April 1999) Female isopods Sphaeroma terebrans Bate 1866 are known to host their oŒspring in family burrows in aerial roots of the red mangrove Rhizophora mangle. During a study on the reproductive biology of S. terebrans in the Indian River Lagoon, Florida, USA, juvenile S. quadridentatum were found in family burrows of S. terebrans. Between September 1997 and August 1998, each month at least one female S. terebrans was found with juvenile S. quadridentatum in its burrow. The percentage of S. terebrans family burrows that contained juvenile S. quadridenta- tum was high during fall 1997, decreased during the winter, and reached high values again in late spring/early summer 1998, corresponding with the percentage of parental female S. terebrans (i.e. hosting their own juveniles). Most juvenile S. quadridentatum were found with parental female S. terebrans, but a few were also found with reproductive females that were not hosting their own oŒspring. Non-reproductive S. terebrans (single males, subadults, non-reproductivefemales) were never found with S. quadridentatum in their burrows. The numbers of S. quadridentatum found in burrows of S. terebrans ranged between one and eight individuals per burrow. No signi® cant correlation between the number of juvenile S. quadridentatum and the numbers of juvenile S. terebrans in a family burrow existed. However, burrows with high numbers of juvenile S. quadridentatum often contained relatively few juvenile S. -

Paradella Dianae – Around the World in 20 Years
Southeastern Regional Taxonomic Center South Carolina Department of Natural Resources Paradella dianae – around the world in 20 years Kingdom Animalia Phylum Arthropoda Class Malacostraca Order Isopoda Family Sphaeromatidae Paradella dianae is a species of crustacean that was accidentally introduced to the southeast coast of the U.S. in the early 1980s. It was first discovered by SCDNR divers who were studying the jetties that were being built at Murrells Inlet at that time. As they made repeated dives on the jetty stones below the low tide level, to carefully and systematically quantify the flora and fauna, divers noticed hundreds of small creatures clinging tightly to their neoprene wetsuits when they climbed from the water back onto the dive boat. It took a lot of effort to remove them, even under the heavy spray of freshwater from a garden hose back at the dock. It turns out that these pesky animals were isopods that are native to the Pacific coasts of North and Central America. They were probably carried to our coast on the outside surfaces of oceangoing ships, and they have hitchhiked around the world among the fouling growth that builds up over time on these ship’s hulls. Although they aren’t particularly conspicuous to the casual observer, isopods are an important part of many coastal communities, as this is especially true for those that live on hard surfaces that are continuously submerged in high salinity seawater for a reasonably long period of time (e.g. floating docks, pilings and jetties). You can learn more about this interesting group of crustaceans by going to the archived ‘Featured Species’ at http://www.dnr.sc.gov/marine/sertc/Isopod%20Crustaceans.pdf Description and Biology: Paradella dianae is a dorso-ventrally flattened, yellowish and brown colored sphaeromatid isopod. -

Ponti 2 1 Corso di Laurea Magistrale in Biologia Marina Alma Mater Studiorum Università di Bologna - [email protected] 2 Dipartimento di Scienze Biologiche, Geologiche ed Ambientali, Alma Mater Studiorum Università di Bologna Abstract Invasions by alien species is one of the most alarming threats that reduces biodiversity and leads to direct or indirect ecological effects on marine ecosystems. Northern Adriatic lagoons are affected by high anthropogenic impacts, which may facilitate the introduction and spreading of alien species. The sphaeromatid isopods Paracerceis sculpta, native to the northeast Pacific, has been found for the first time Pialassa Baiona, a brackish lagoon connected to Ravenna harbour, in 2012. Field data suggest that P. sculpta became a pest species, being more competitive compare to the two native sphaeromatid species inhabiting the lagoon. Keywords: Lagoons, Alien species, Brackish water, Crustacea, North Adriatic Sea Introduction Northern Adriatic coastal lagoons show a high rate of introduction needed to confirm that P. sculpta is more competitive than the native species of alien species compared with other coastal regions, becoming one of the major and it has a true impact in term of loss of ecological functions. hot spot of invasion in the Mediterranean basin ([1], [2]). Human disturbance and the increase of vessel traffic countries is an important pathway of spreading of alien species in stressed environments ([2]). Paracerceis sculpta (Holmes, 1904) is one interesting examples of alien species introduced to costal lagoons. -

A, 4ème étage, pièce 405, 7 quai St Bernard, 75005 Paris, France Abstract Exosphaeroides quirosi is described from a karstic stream and its associated cave sink located 390 m above sea level and 23.5 km inland from the east coast of Espíritu Santo (Vanuatu, SW Pacific ocean). This is the first purely freshwater sphaeromatid isopod reported from an oceanic island, and is a new example of colonization of an oceanic island freshwa- ter habitat by a typically marine taxon. E. quirosi differs from any other representative of the family in the peculiar con- dition displayed by the exopod of pleopod 4, which has a falcate outline, is distinctly longer than the corresponding endopod, and has the medial margin of the proximal segment produced into a foliaceous endite. Seemingly, the sexual dimorphism expressed in the presence/absence of a setulose fringe on the pereopods has not been recorded in any other sphaeromatid. -
