Phylogenetic relationships of species of Raymunida (Decapoda: Galatheidae) based on morphology and mitochondrial cytochrome oxidase sequences, with the recognition of four new species

19 pages.-- RECEIVED: 10 April 2000, ACCEPTED: 8 November 2000.The species of the genus Raymunida from the Pacific and Indian oceans are revised using morphological characters and the mitochondrial cytochrome oxidase subunit I sequences. Four new species are described (R. confundens, R. dextralis, R. erythrina, and R. insulata), and the status of R. bellior and R. elegantissima are revised. The species of Raymunida can be identified by subtle morphological characters, which match differences in mitochondrial nucleotide sequences. Therefore, the sequence divergences confirm the specific and phylogenetic value of some morphological characters (e.g., length of the mesial spine on the basal antennal segment, length of the walking legs). Furthermore, they confirm the importance of the color pattern as a diagnostic character. The widespread species (R. elegantissima), known from the Philippines to Fiji, shows minimal divergence between specimens from different localities (maximum of 3 nucleotide differences or 0.2% mean divergence). The phylogenetic reconstruction agreed with the monophyletic condition of Raymunida and its differentiation with respect to the genus Munida (in which Raymunida species had previously been included) and Agononida.Peer reviewe

Checklist of marine Crustacea Decapoda (excluded Brachyura) from Iberian Peninsula

An actualized and annotated checklist of marine Crustacea Decapoda (excluded Brachyura) from Iberian Peninsula and by sectors (Northern Spain (Gulf of Biscay to Galicia) - West Portugal - Gulf of Cádiz (S Portugal- SW Spain: Cape San Vicente to Gibraltar Strait) - Alborán Sea - Eastern Mediterranean Spain (Baleares-Levante)) is provided. Systematic changes and synonymies, new records, introduced species by anthropogenic activities and characterization of the spatial distribution of species are commented. In total 292 decapods species (not including Brachyura), belonging to 134 genera and 42 families, are cited along Iberian waters. Of these, 114 were not found by Zariquiey Álvarez (1968). The richest families are Paguridae, Hippolytidae and Palemonidae (with 28, 21 and 17 species respectively). By sectors, the Gulf of Cadiz shows the highest richness (178 species), consequence of the confluence of Atlantic and Mediterranean waters and of a greater depth range in this area (when comparing with the adjacent Alborán Sea sector). The total marine decapod species along Iberian waters (including crabs, Marco-Herrera et al., 2015) is, at least, 431. Also, other 13 freshwaters species have been cited in Iberian Peninsula.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Species of the genus Munidopsis (Crustacea, Decapoda, Galatheidae) from the deep Atlantic Ocean, including cold-seep and hydrothermal vent areas.

60 páginas, 16 figuras, 3 tablas.Twenty-two species of the genus Munidopsis from the Atlantic Ocean are studied. Five new species are described (M. anemia, M. exuta, M. hirtella, M. laurentae and M. truculenta), and diagnoses and illustrations of some relatively rare species (M. acuminata, M. bairdii, M. livida, M. parfaiti and M. thieli) are provided. None of the species discussed here is restricted to a particular habitat, including species collected from hydrothermal vent (M. acutispina, M. exuta) and cold seep areas (M. acutispina, M. geyeri, M. hirtella, M. livida, M. marionis). The new records of some species greatly extend the previously known distribution range of the species (i.e., M. abyssicola, M. aries, M. bairdii, M. geyeri, M. livida, M. parfaiti, M. thieli). Finally, some biological and biogeographical data for the different species are discussedThe BENGAL cruises were organized in the framework of the European project BENGAL, contract n° MAS3-CT95-0018 (DG12-ESCY). The material of the cruises BIOZAÏRE 1 and 2, and ZAIROV were obtained through the framework of the multidisciplinary environmental program BIOZAÏRE realized in partnership between Ifremer and Total Oil Company.Peer reviewe

A new species of Paramunida Baba, 1988 from the Central Pacific Ocean and a new genus to accommodate P. granulata (Henderson, 1885)

18 páginas, 4 figuras.The genus Paramunida belongs to the most diverse family of galatheoids and it is commonly reported from the continental slope across the Indian and Pacific Oceans. Examination of material collected by the NOAA RV Townsend Cromwell Cruise near Christmas (Kiritimati) Island, Kiribati, revealed the existence of a new species of Paramunida (P. haigae), which represents the fourth record of the genus for the Central Pacific. Furthermore, recent efforts to unravel phylogenetic relationships and diversification patterns in Paramunida revealed P. granulata (Henderson, 1885) to be the most basally diverging taxon within the genus. This species is clearly distinguished from other species of Paramunida by the spinulation of the carapace and the length of the distomesial spine of the second antennal peduncle article, which in combination with a high level of genetic divergence suggest that this species represents a separate monotypic lineage. A new genus, Hendersonida gen. n., is proposed to accommodate this species based on morphological and molecular evidence. An updated dichotomous identification key for all species of Paramunida is presented.PC was funded by Research and Collections, Natural History Museum of Los Angeles County.Peer reviewe

New sibling species and new occurrences of squat lobsters (Crustacea, Decapoda) from the western Indian Ocean

Este artículo contiene 61 páginas, 3 tablas, 14 figuras.Numerous specimens of squat lobsters belonging to the families Munididae, Munidopsidae and Eumunididae were collected during several cruises along the eastern coasts of Africa. The study of these specimens revealed the presence of 10 new species (one Eumunida Smith, 1883, eight Munida Leach, 1820 and one Munidopsis Whiteaves, 1874). We describe and illustrate these new species, providing some new data on occurrences and colour patterns for previously described taxa. We have also included molecular data from two mitochondrial markers (16S rRNA and COI) to support the taxonomic status of different species. Some deep-sea species show a clear increase in their geographic range distribution. Finally, a key to known species of the genus Munida from the western and central Indian Ocean is also presented.The MAINBAZA cruise, a joint project of MNHN (P. Bouchet principal investigator) and Instituto Español de Oceanografía (A. Ramos principal investigator), and the ATIMO VATAE and MIRIKY cruises formed part of a cluster of Mozambique- Madagascar expeditions (La Planète Revisitée/Our Planet Reviewed) funded by the Total, Prince Albert II of Monaco, and Stavros Niarchos foundations, and conducted by MNHN and Pro-Natura International. The figures of the carapaces were illustrated by J. Macpherson. Molecular data were obtained thanks to the partial support of a Spanish Ministry of Economy and Competitiveness project (ref.

Estimación de la diversidad genética y del tamaño efectivo de la población de coquina Donax trunculus del Parque Nacional de Doñana y su contribución a áreas no protegidas

Este capítulo contiene 16 páginas, 4 tablas, 6 figuras.[EN]We have studied seven populations of the wedge clam Donax trunculus, distributed throught the Spanish Atlantic and Mediterranean coasts. A comparative analysis of size and density was performed from a sample obtained from a commercially exploited population from Isla Canela, and from another population which is managed under a strict plan using only artisanal hand dredging from the beach of the Doñana National Park showing that the management carried out in the Doñana National Park is correct and allows sustainable fisheries. Twenty one microsatellite loci were isolated and characterized in D. trunculus of which 16 were polymorphic and codominant. At least 12 of them have high frequencies of null alleles in all populations, and the rest in most populations. All collected samples were genotyped with these 16 loci and genetic diversity indices, tests of disequiibrium, fixation indices and probabilities of genetic differentiation among localities were determined. The odds of assignment to the sampling location were also determined. Several analyses were conducted to determine the potential causes for the deviations from Hardy-Weinberg equilibrium which shown that they were mainly due to the presence of null alleles. Furthermore, using the ribosomal internal transcribed spacer it was determined that the commercially exploited populations of the wedge clam under the specific name Donax trunculus are actually a mixture of a hybrid and non-hybrid species. The analysis of the genetic structure made both to all individuals and separately for hybrid and non-hybrid individuals showed four genetically distinct populations in the Spanish coast. The first in the Cantabric Sea, the second in the Gulf of Cadiz, the third from the Strait of Gibraltar to Cabo de Gata and the last one from the Cabo de Gata to the Gulf of Rosas.[ES]Se han estudiado ejemplares de coquina, Donax trunculus en 7 localidades distribuidas por las costas peninsulares atlánticas y mediterráneas españolas. Se ha hecho un análisis comparado de datos de tallas y densidad obtenidos en una localidad explotada (Isla Canela) y otra protegida (playa del Parque Nacional de Doñana), que muestran que la gestión llevada a cabo en el Parque Nacional Doñana es la correcta y permite una pesca sostenible. Se aislaron y caracterizaron 21 loci de microsatélites de los cuales 16 resultaron polimórficos y codominantes. De ellos al menos 12 presentan elevadas frecuencias de alelos nulos en todas las poblaciones, y el resto en la mayoría de poblaciones. Todas las muestras fueron genotipadas con estos 16 loci y se determinaron los índices de diversidad genética, pruebas de equilibrio, índices de fijación y las probabilidades de diferenciación entre localidades. También se determinaron las probabilidades de asignación a la localidad de muestreo. Se realizaron diversos análisis para determinar las causas potenciales de las desviaciones del equilibrio de Hardy-Weinberg y se demostró que se deben principalmente a alelos nulos. Se descubrió mediante el análisis del marcador ribosomal ITS que las poblaciones de coquina explotadas comercialmente en España bajo la denominación específica Donax trunculus son en realidad una mezcla de una especie híbrida y una no híbrida. El análisis de la estructura genética, tanto el realizado a todos los individuos como de forma separada para individuos híbridos y no-híbridos, demostró que existen cuatro poblaciones genéticamente distintas en el litoral español. La primera en el Mar Cantábrico, la segunda en el Golfo de Cádiz, la tercera entre el Estrecho de Gibraltar y el Cabo de Gata y la última entre el Cabo de Gata y el Golfo de Rosas.Queremos agradecer en primer lugar al Organismo Autónomo Parques Nacionales por la concesión del proyecto que permitió el presente estudio. A la oficina de coordinación del Parque Nacional de Doñana por las facilidades prestadas para los muestreos en la playa de Doñana. Nuestro agradecimiento también a Consejería de Agricultura, Pesca y Desarrollo Rural de la Junta de Andalucía por compartir sus datos sobre la densidad de coquinas en el Golfo de Cádiz y facilitar los permisos de pesca en los diferentes puntos de Andalucía. Y como no, gracias también a los mariscadores y pescadores de Sanlú- car de Barrameda (Cádiz) y de Cabo de Gata (Almería) que nos acompañaron en los diferentes muestreos.Peer reviewe

Fish assemblages across the Mediterranean Sea and the effects of protection from fishing = I Popolamenti ittici nel Mediterraneo e gli effetti della protezione dall’impatto della pesca

Several studies have assessed the effectiveness of individual marine protected areas (MPAs) in protecting fish assemblages, but regional assessments of multiple parks are scarce. Here fish surveys using visual census were done in marine parks and fished areas at 31 locations across the Mediterranean Sea. Fish species richness, diversity and biomass (especially of top predators) were higher in MPAs compared to fished areas, and community structure differed significantly between MPAs and fished areas. Results suggest that MPAs are generally effective means to protect and recover fish populations and assemblages

On some squat lobsters from India (Decapoda, Anomura, Munididae), with description of a new species of Paramunida Baba, 1988

20 páginas, 4 figuras.Squat lobster specimens belonging to the family Munididae were recently collected along the southwestern coast of the mainland of India and in the Andaman Islands. The specimens belong to two known species, Agononida prolixa (Alcock, 1894) and Munida compacta Macpherson, 1997, and a new species, Paramunida bineeshi sp. nov. We here redescribe A. prolixa and describe and figure the new species. Munida compacta is newly recorded from India, and we figure the live coloration. In addition, molecular and phylogenetic analyses of two mitochondrial markers (16S rRNA and COI) revealed the phylogenetic relationships of M. compacta and P. bineeshi sp. nov. with their most closely related congeners. The genetic similarity among the individuals of M. compacta from different locations is also addressed.Peer reviewe
