FAX: (506) 207-3280. E-mail: [email protected] 3Escuela de Biología, Universidad de Costa Rica, 2060 San José, Costa Rica. (Received 14-VII-2000. Corrected 23-III-2001. Accepted 11-V-2001) Abstract: The mollusks in Manuel Antonio National Park on the central section of the Pacific coast of Costa Rica were studied along thirty-six transects done perpendicular to the shore, and by random sampling of subtidal environments, beaches and mangrove forest. Seventy-four species of mollusks belonging to three classes and 40 families were found: 63 gastropods, 9 bivalves and 2 chitons, during this study in 1995. Of these, 16 species were found only as empty shells (11) or inhabited by hermit crabs (5). Forty-eight species were found at only one locality. Half the species were found at one site, Puerto Escondido. The most diverse habitat was the low rocky intertidal zone. Nodilittorina modesta was present in 34 transects and Nerita scabricosta in 30. Nodilittorina aspera had the highest density of mollusks in the transects. Only four transects did not clustered into the four main groups. The species composition of one cluster of transects is associated with a boulder substrate, while another cluster of transects associates with site. -

Av. Benavides 5400, Surco. P.O. Box 18-131. Lima, Perú. Abstract: Peru is an ecologically diverse country, with 84 life zones in the Holdridge system and 18 ecological regions (including two marine). 1910 molluscan species have been recorded. The highest number corresponds to the sea: 570 gastropods, 370 bivalves, 36 cephalopods, 34 polyplacoforans, 3 monoplacophorans, 3 scaphopods and 2 aplacophorans (total 1018 species). The most diverse families are Veneridae (57spp.), Muricidae (47spp.), Collumbellidae (40 spp.) and Tellinidae (37 spp.). Biogeographically, 56 % of marine species are Panamic, 11 % Peruvian and the rest occurs in both provinces; 73 marine species are endemic to Peru. Land molluscs include 763 species, 2.54 % of the global estimate and 38 % of the South American esti- mate. The most biodiverse families are Bulimulidae with 424 spp., Clausiliidae with 75 spp. and Systrophiidae with 55 spp. In contrast, only 129 freshwater species have been reported, 35 endemics (mainly hydrobiids with 14 spp. The paper includes an overview of biogeography, ecology, use, history of research efforts and conser- vation; as well as indication of areas and species that are in greater need of study. -

Si bien la tendencia general de las capturas de abulón indica una disminución de las dos principales especies que la conforman (Haliotis fulgens y H corrugata), a partir de su máximo histórico en 1950, esta tendencia no ha sido uniforme ni entre especies ni entre las regiones de donde se extrae. -
Marine Boring Bivalve Mollusks from Isla Margarita, Venezuela
ISSN 0738-9388 247 Volume: 49 THE FESTIVUS ISSUE 3 Marine boring bivalve mollusks from Isla Margarita, Venezuela Marcel Velásquez 1 1 Museum National d’Histoire Naturelle, Sorbonne Universites, 43 Rue Cuvier, F-75231 Paris, France; [email protected] Paul Valentich-Scott 2 2 Santa Barbara Museum of Natural History, Santa Barbara, California, 93105, USA; [email protected] Juan Carlos Capelo 3 3 Estación de Investigaciones Marinas de Margarita. Fundación La Salle de Ciencias Naturales. Apartado 144 Porlama,. Isla de Margarita, Venezuela. ABSTRACT Marine endolithic and wood-boring bivalve mollusks living in rocks, corals, wood, and shells were surveyed on the Caribbean coast of Venezuela at Isla Margarita between 2004 and 2008. These surveys were supplemented with boring mollusk data from malacological collections in Venezuelan museums. A total of 571 individuals, corresponding to 3 orders, 4 families, 15 genera, and 20 species were identified and analyzed. The species with the widest distribution were: Leiosolenus aristatus which was found in 14 of the 24 localities, followed by Leiosolenus bisulcatus and Choristodon robustus, found in eight and six localities, respectively. The remaining species had low densities in the region, being collected in only one to four of the localities sampled. The total number of species reported here represents 68% of the boring mollusks that have been documented in Venezuelan coastal waters. This study represents the first work focused exclusively on the examination of the cryptofaunal mollusks of Isla Margarita, Venezuela. KEY WORDS Shipworms, cryptofauna, Teredinidae, Pholadidae, Gastrochaenidae, Mytilidae, Petricolidae, Margarita Island, Isla Margarita Venezuela, boring bivalves, endolithic. INTRODUCTION The lithophagans (Mytilidae) are among the Bivalve mollusks from a range of families have more recognized boring mollusks. -

An outline of cassoidean phylogeny (Mollusca, Gastropoda). — Contr. Tert. Quatern. Geo!., 32(4): 97-132, 43 figs. Leiden, December 1995. The phylogeny of cassoidean gastropods is reviewed, incorporating most of the biological and palaeontological data from the literature. Several characters have been checked personally and some new data are presented and included in the cladistic analysis. The Laubierinioidea, Calyptraeoidea and Capuloidea are used as outgroups. Twenty-three apomorphies are discussed and used to define cassoid relations at the subfamily level. A classification is presented in which only three families are recognised. The Ranellidae contains the subfamilies Bursinae, Cymatiinae and Ranellinae. The Pisanianurinae is removed from the Ranellidae and attributed to the Laubierinioidea.The Cassidae include the Cassinae, Oocorythinae, Phaliinae and Tonninae. The Ranellinae and Oocorythinae are and considered the of their families. The third the both paraphyletic taxa are to represent stem-groups family, Personidae, cannot be subdivided and for anatomical evolved from Cretaceous into subfamilies reasons probably the same Early gastropod ancestor as the Ranellidae. have from Ranellidae the Late Cretaceous. The Cassidae (Oocorythinae) appears to branched off the (Ranellinae) during The first significant radiation of the Ranellidae/Cassidaebranch took place in the Eocene.

Gradual Miocene to Pleistocene Uplift of the Central American Isthmus: Evidence from Tropical American Tonnoidean Gastropods Alan G

Paleont., 75(3), 2001, pp. 706±720 Copyright q 2001, The Paleontological Society 0022-3360/01/0075-706$03.00 GRADUAL MIOCENE TO PLEISTOCENE UPLIFT OF THE CENTRAL AMERICAN ISTHMUS: EVIDENCE FROM TROPICAL AMERICAN TONNOIDEAN GASTROPODS ALAN G. BEU Institute of Geological and Nuclear Sciences, P O Box 30368, Lower Hutt, New Zealand, ,[email protected]. ABSTRACTÐTonnoidean gastropods have planktotrophic larval lives of up to a year and are widely dispersed in ocean currents; the larvae maintain genetic exchange between adult populations. They therefore are expected to respond rapidly to new geographic barriers by either extinction or speciation. Fossil tonnoideans on the opposite coast of the Americas from their present-day range demonstrate that larval transport still was possible through Central America at the time of deposition of the fossils. Early Miocene occurrences of Cypraecassis tenuis (now eastern Paci®c) in the Caribbean probably indicate that constriction of the Central American seaway had commenced by Middle Miocene time. Pliocene larval transport through the seaway is demonstrated by Bursa rugosa (now eastern Paci®c) in Caribbean Miocene-latest Pliocene/Early Pleistocene rocks; Crossata ventricosa (eastern Paci®c) in late Pliocene rocks of Atlantic Panama; Distorsio clathrata (western Atlantic) in middle Pliocene rocks of Ecuador; Cymatium wiegmanni (eastern Paci®c) in middle Pliocene rocks of Atlantic Costa Rica; Sconsia sublaevigata (western Atlantic) in Pliocene rocks of Darien, Paci®c Panama; and Distorsio constricta (eastern Paci®c) in latest Pliocene-Early Pleistocene rocks of Atlantic Costa Rica. Continued Early or middle Pleistocene connections are demonstrated by Cymatium cingulatum (now Atlantic) in the Armuelles Formation of Paci®c Panama. -

[email protected] ABSTRACT. In the present study, we describe and analyze the structure of a Late Pleistocene (likely last interglacial) marine macrobenthic assemblage in Caleta Patillos (20°45’S, 70°12’W), northern Chile. A taphonomic analysis sug- gests the existence of a shallow subtidal paleonvironment, mainly soft-bottom, of high energy and intense mixing from several benthic habitats. The total number of 38 taxa recorded, mainly gastropods and bivalves, was not different than the ones reported in other Late Pleistocene assemblages in northern Chile. At a biogeographic scale, the composition of mollusk species showed remarkable similarities with present-day fauna, and no extralimital species were recorded. At local scale, however, a comparison with the living assemblage in the same area of study showed a dramatic shift in the species’ composition, a result that cannot be explained by sampling bias. A deep and perhaps very recent (i.e., at historical times) alteration of the structure of local macrobenthic assemblages is hypothesized.
