  • Os Nomes Galegos Dos Moluscos
    A Chave Os nomes galegos dos moluscos 2017 Citación recomendada / Recommended citation: A Chave (2017): Nomes galegos dos moluscos recomendados pola Chave. http://www.achave.gal/wp-content/uploads/achave_osnomesgalegosdos_moluscos.pdf 1 Notas introdutorias O que contén este documento Neste documento fornécense denominacións para as especies de moluscos galegos (e) ou europeos, e tamén para algunhas das especies exóticas máis coñecidas (xeralmente no ámbito divulgativo, por causa do seu interese científico ou económico, ou por seren moi comúns noutras áreas xeográficas). En total, achéganse nomes galegos para 534 especies de moluscos. A estrutura En primeiro lugar preséntase unha clasificación taxonómica que considera as clases, ordes, superfamilias e familias de moluscos. Aquí apúntase, de maneira xeral, os nomes dos moluscos que hai en cada familia. A seguir vén o corpo do documento, onde se indica, especie por especie, alén do nome científico, os nomes galegos e ingleses de cada molusco (nalgún caso, tamén, o nome xenérico para un grupo deles). Ao final inclúese unha listaxe de referencias bibliográficas que foron utilizadas para a elaboración do presente documento. Nalgunhas desas referencias recolléronse ou propuxéronse nomes galegos para os moluscos, quer xenéricos quer específicos. Outras referencias achegan nomes para os moluscos noutras linguas, que tamén foron tidos en conta. Alén diso, inclúense algunhas fontes básicas a respecto da metodoloxía e dos criterios terminolóxicos empregados. 2 Tratamento terminolóxico De modo moi resumido, traballouse nas seguintes liñas e cos seguintes criterios: En primeiro lugar, aprofundouse no acervo lingüístico galego. A respecto dos nomes dos moluscos, a lingua galega é riquísima e dispomos dunha chea de nomes, tanto específicos (que designan un único animal) como xenéricos (que designan varios animais parecidos).

This family, comprising 29 genera, shows a remarkable diversity of habitat preferences, feeding, and behaviours. Twenty-four species belonging to seven genera have been reported in the Eastern Pacific region. The present study focuses on the relationship between the diet and the cephalic profile in the 24 endemic damselfishes of this region. Feeding habits were determined by means of underwater observations and the gathering of bibliographic data. Variations in cephalic profile were analyzed by means of geometric morphometrics and phylogenetic methods. The present study shows that the 24 species can be grouped into three main trophic guilds: zooplanktivores, algivores, and an intermediate group feeding on small pelagic and benthic preys. Shape variations were low within each genus except for Abudefduf. Phylogenetically adjusted regression reveals that head shape can be explained by differences in feeding habits.

Accepted: July 28, 2018 Data deposition: Raw RNA seq data: SRA database: project number SRP139515 (SRR6983161-SRR6983169) Abstract The transcriptome of the venom duct of the Atlantic piscivorous cone species Chelyconus ermineus (Born, 1778) was determined. The venom repertoire of this species includes at least 378 conotoxin precursors, which could be ascribed to 33 known and 22 new (unassigned) protein superfamilies, respectively. Most abundant superfamilies were T, W, O1, M, O2, and Z, accounting for 57% of all detected diversity. A total of three individuals were sequenced showing considerable intraspecific variation: each individual had many exclusive conotoxin precursors, and only 20% of all inferred mature peptides were common to all individuals. Three different regions (distal, medium, and proximal with respect to the venom bulb) of the venom duct were analyzed independently. Diversity (in terms of number of distinct members) of conotoxin precursor superfamilies increased toward the distal region whereas transcripts detected toward the proximal region showed higher expression levels.

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.

  • Snake Eels (Ophichthidae) of the Remote St. Peter and St. Paul's Archipelago (Equatorial Atlantic): Museum Records After 37 Ye
    Arquipelago - Life and Marine Sciences ISSN: 0873-4704 Snake eels (Ophichthidae) of the remote St. Peter and St. Paul’s Archipelago (Equatorial Atlantic): Museum records after 37 years of shelf life OSMAR J. LUIZ AND JOHN E. MCCOSKER Luiz, O.J. and J.E. McCosker 2018. Snake eels (Ophichthidae) of the remote St. Peter and St. Paul’s Archipelago (Equatorial Atlantic): Museum records after 37 years of shelf life. Arquipelago. Life and Marine Sciences 36: 9 - 13. Despite of its major zoogeographical interest, the biological diversity of central Atlantic oceanic islands are still poorly known because of its remoteness. Incomplete species inventories are a hindrance to macroecology and conservation because knowledge on species distribution are important for identifying patterns and processes in biodiversity and for conservation planning. Records of the snake-eel family Ophichthidae for the St. Peter and St. Paul’s Archipelago, Brazil, are presented for the first time after revision of material collected and deposited in a museum collection 37 yrs ago. Specimens of Apterichtus kendalli and Herpetoichthys regius were collected using rotenone on sand bottoms and one Myrichthys sp. was observed and photographed swimming over a rocky reef. Remarkably, these species were not seen or collected in the St. Peter and St. Paul’s Archipelago ever since despite the substantial increase of biological expeditions over the past two decades, suggesting that the unjustified rotenone sampling prohibition in Brazil is hindering advancement of the nation’s biological diversity knowledge. Key words: Central Atlantic islands, Anguilliformes, sampling bias, rotenone prohibition. Osmar J.

  • First Observation and Range Extension of the Nudibranch Tenellia Catachroma (Burn, 1963) in Western Australia (Mollusca: Gastropoda)
    CSIRO Publishing The Royal Society of Victoria, 129, 37–40, 2017 www.publish.csiro.au/journals/rs 10.1071/RS17003 A VICTORIAN EMIGRANT: FIRST OBSERVATION AND RANGE EXTENSION OF THE NUDIBRANCH TENELLIA CATACHROMA (BURN, 1963) IN WESTERN AUSTRALIA (MOLLUSCA: GASTROPODA) Matt J. NiMbs National Marine Science Centre, Southern Cross University, PO Box 4321, Coffs Harbour, NSW 2450, Australia Correspondence: [email protected] ABSTRACT: The southwest coast of Western Australia is heavily influenced by the south-flowing Leeuwin Current. In summer, the current shifts and the north-flowing Capes Current delivers water from the south to nearshore environments and with it a supply of larvae from cooler waters. The nudibranch Tenellia catachroma (Burn, 1963) was considered restricted to Victorian waters; however, its discovery in eastern South Australia in 2013 revealed its capacity to expand its range west. In March 2017 a single individual was observed in shallow subtidal waters at Cape Peron, Western Australia, some 2000 km to the west of its previous range limit. Moreover, its distribution has extended northwards, possibly aided by the Capes Current, into a location of warming. This observation significantly increases the range for this Victorian emigrant to encompass most of the southern Australian coast, and also represents an equatorward shift at a time when the reverse is expected. Keywords: climate change, Cape Peron, range extension, Leeuwin Current, Capes Current The fionid nudibranch Tenellia catachroma (Burn, 1963) first found in southern NSW in 1979 (Rudman 1998), has was first described from two specimens found at Point been observed only a handful of times since and was also Danger, near Torquay, Victoria, in 1961 (Burn 1963).

  • Phylogenetic Analyses of Marine Sponges Within the Order Verongida: a Comparison of Morphological and Molecular Data
    Invertebrate Biology 126(3): 220–234. r 2007, The Authors Journal compilation r 2007, The American Microscopical Society, Inc. DOI: 10.1111/j.1744-7410.2007.00092.x Phylogenetic analyses of marine sponges within the order Verongida: a comparison of morphological and molecular data Patrick M. Erwin and Robert W. Thackera University of Alabama at Birmingham, Birmingham, Alabama 35294, USA Abstract. Because the taxonomy of marine sponges is based primarily on morphological characters that can display a high degree of phenotypic plasticity, current classifications may not always reflect evolutionary relationships. To assess phylogenetic relationships among sponges in the order Verongida, we examined 11 verongid species, representing six genera and four families. We compared the utility of morphological and molecular data in verongid sponge systematics by comparing a phylogeny constructed from a morphological character matrix with a phylogeny based on nuclear ribosomal DNA sequences. The morphological phylogeny was not well resolved below the ordinal level, likely hindered by the paucity of characters available for analysis, and the potential plasticity of these characters. The molec- ular phylogeny was well resolved and robust from the ordinal to the species level. We also examined the morphology of spongin fibers to assess their reliability in verongid sponge tax- onomy. Fiber diameter and pith content were highly variable within and among species. Despite this variability, spongin fiber comparisons were useful at lower taxonomic levels (i.e., among congeneric species); however, these characters are potentially homoplasic at higher taxonomic levels (i.e., between families). Our molecular data provide good support for the current classification of verongid sponges, but suggest a re-examination and potential reclas- sification of the genera Aiolochroia and Pseudoceratina.
