the shells of various species of nassarius are popular with shell collectors , and are sometimes used in jewelry and other forms of decoration .

nassarius vibex is a species which is often selected for marine aquaria . it is often confused with nassarius obsoletus , a cooler water snail less suited to tropical marine aquarium temperatures . in aquaria , the nassarius is considered nearly indispensable for keeping sand beds clean and healthy , as these snails tend to burrow and plow through the upper layer in a conch - like fashion , keeping algae and detritus from building up visibly on the surface .

nassarius oneratus seems to prefer relatively shallow water on both eastern and western seaward reefs , but can also be found on some lagoon pinnacles . on the seaward reef , it often lives buried under thin layers of sand over hard reef up on the flat in shallow water . on the intertidal , reasonably fresh - looking shells inhabited by hermit crabs are common in some places , but we have not seen living animals in those areas . it is possible that shells living on the shallow seaward reefs are regularly tossed up on the reefs , where they are taken over by hermits . maximum size we have seen is 15 . 2mm .

nassa lamarck , 1799 : established for the species buccinum mutabile linnaeus , 1758 , which is now classified as a synonym of nassarius duméril , 1805 in the family nassariidae .

according to van regteren altena et al . ( 1965 ) and van aartsen et al . ( 1984 ) hinia gray , 1847 is considered as a subgenus of nassarius duméril , 1806 .

the name is derived from the latin word " nassa " , meaning a wickerbasket with a narrow neck , for catching fish . nassarius would then mean " someone who uses such a wickerbasket for catching fish " .

most nassarius species are very active scavengers , feeding on crabs and carrion as dead fish , etc . they often burrow into marine substrates and then wait with only their siphon protruding , until they smell nearby food .

sicydium is a genus of gobies native to fast-flowing streams and rivers of the americas ( central america , mexico , cocos island , the caribbean , colombia , ecuador and venezuela ) with a couple species native to middle africa .

notes on the biology of the gobiid fish sicydium plumieri in puer . . . : ingenta connect

the genus sicydium is in the family cucurbitaceae in the major group angiosperms ( flowering plants ) .

the artisanal fishery industry in the caribbean for sicydium species is widespread and often intense ( bell et al . 1995 ) .

the plant list includes 14 scientific plant names of species rank for the genus sicydium . of these 8 are accepted species names .

the artisanal fishery industry in the caribbean for sicydium species is widespread and often intense ( bell et al . 1995 ) . fishery declines in sicydium species have been reported in other regions ( bell et al . 1995 ) . the reason for these declines is not clear as no landing statistics are available . habitat degradation and over - exploitation have both been suggested as potential causes of these declines ( bell 1999 ) .

we report collections of several specimens of sicydium in 2013 and 2014 from the jubones and santa rosa rivers in southwestern ecuador . these collections substantially expand the known range of the genus southward . the specimens are tentatively identified as sicydium cf . rosenbergii based on their morphology . small differences in morphology among specimens from the two rivers are noted , as are discrepancies with the type description . a museum database search uncovered two additional records of the genus south of their previously recognized range including one record from northwestern peru .

the plant list includes a further 1 scientific plant names of infraspecific rank for the genus sicydium . we do not intend the plant list to be complete for names of infraspecific rank . these are primarily included because names of species rank are synonyms of accepted infraspecific names .

thank you for taking the time to provide feedback on the iucn red list of threatened species website , we are grateful for your input .

western atlantic species of this genus are in need of revision ( e . murdy pers . comm . 2009 , f . pezold pers . comm . 2010 ) .

justification : this widely distributed , amphidromous species can be locally abundant where it occurs in rivers of coastal volcanic topography . it can recruit among streams of different islands due to its pelagic marine larvae . the subpopulation on dominica has suffered severe declines due to habitat degradation and overexploitation . these threats are not known to be impacting its global population , therefore , it is listed as least concern . improved management of its vulnerable habitat and exploited subpopulations is recommended .

this species has been recorded in the western atlantic in the antilles from jamaica to trinidad and tobago ( kullander 2003 ) , along the central american coast from honduras to panama ( murdy and hoese 2002 , matamoros et al . 2009 , tornabene and pezold pers . comm . 2011 ) , and along the south american coast from venezuela and in the coastal drainages of bahia state , brazil ( de lucena et al . 2013 ) .

this species has exhibited severe population declines in dominica ( bell pers . comm . ) . these declines have been attributed both to over - exploitation and habitat degradation / alteration ( bell 1999 ) . this species is prominent in puerto rican streams ( cook et al . 2009 , f . pezold pers . comm . 2011 ) .

this is a demersal amphidromous species found in rivers of coastal volcanic topography ( bell 1994 ) . adults spawn in rivers with coarse substrate , building nests under stones ( bell 1999 ) . it excavates nests below the gravel bottom . males provide most of the parental care . newly hatched larvae emerge from nests upon hatching and enter the river plankton . they migrate to the sea where they stay for 50 - 150 days before re - entering the rivers as postlarvae . this species feeds on filamentous algae and other soft vegetation .

spp . , support fisheries based on return migrations of postlarvae ( fry ) to rivers . in dominica , larva of this species contribute > 95 % to the goby fry fishery ( bell 1999 ) .

there are no species - specific conservation measures . additional research is needed into the impact of habitat degradation and exploitation on this species .

range ecuador : type locality is described as paramba at 3500 feet ( 1066 . 8 m ) above sea level in northwestern ecuador ( boulenger , 1899 ) . listed as occurring in the santiago - cayapas and esmeraldas drainage systems ( barriga , 2012 ; jimenez et al . , 2016 ) . aguirre et al . ( 2017 ) recently reported collections from southwestern ecuador including the jubones and santa rosa rivers in el oro province ( close to peru ) , although the identification to species was only tentative and needs to be confirmed .

range outside of ecuador : historically , this species has been considered endemic to ecuador , however , a specimen collected in the chancay river in northwestern peru has recently been reported suggesting that s . rosenbergii may also occur in peru ( rom 91180 ; reported in aguirre et al . , 2017 ) . this record needs to be confirmed .

maximum size : 113 mm total length based on two specimens in species description ( boulenger , 1899 ) . fishbase ( 2016 ) lists a maximum size of 11 cm tl as well . probably grows to larger sizes .

economic importance : specific information on this species is not available although historically larvae of the genus were exploited as food by local inhabitants of western ecuador ( jimenez et al . , 2015 ) .

conservation status : specific information on this species is not available although given its migratory life style and the state of many rivers in western ecuador , it may be under threat . research on its conservation status is needed .

has been assessed as data deficient . there are no separate catch statistics available on this species , but reports indicate that species within this genus are intensively exploited . fishery declines in

species have been reported for other regions where fisheries are intensively exploited . fisheries target the larvae , which may cause serious declines in the adult population , but data on the adult population are lacking . pressures from

fisheries are likely to continue while there are no limits on fishing effort or catch size .

further research and monitoring of possible conservation measures , population numbers and harvest levels are needed to prevent this species becoming threatened . it is particularly important to gather data on the status of the adult population occurring in freshwater habitats ; without this information it is impossible to determine trends in population size or decline rates .

is a demersal , diadromous goby . adults live in freshwater where they spawn and larvae migrate downstream into marine waters within the continental shelf . the congener ,

is thought to be long - lived ( more than five years ) and iteroparous ( i . e . , it produces offspring in successive—annual or seasonal—batches ) .

there are no species - specific conservation measures in place for this species . however , its distribution may cover a number of marine protected areas . monitoring of the population numbers and harvest levels of this species is needed . further research should be conducted on possible conservation measures such as closed seasons during peak spawning periods .

the evolution of gastropod body size in the deep sea is reexamined . using an extended and updated data set , and improved statistical methods , it is shown that some results of the previous study may have been artifactual , but that its central conclusion is robust . it is further shown that the effect is not restricted to a single gastropod clade , that its strength increases markedly with depth , but that it applies even in the mesopelagic zone .

the replication of the island rule in a distant taxonomic group and a partially analogous ecological situation could help to uncover the causes of the patterns observed—which are currently much disputed . the gastropod pattern is evident at intermediate depths , and so cannot be attributed to the unique features of abyssal ecology .

funding : some preliminary work undertaken when jw was funded by bbsrc grant do17750 awarded to andrew rambaut . the funders had no role in study design , data collection and analysis , decision to publish , or preparation of the manuscript .

here , i re - examine whether deep - sea gastropods manifest the island rule , making use of the improved statistical methods , and data collated from the recently updated malacolog database [ 24 ] , which has been both expanded , and revised to reflect advances in gastropod systematics [ 25 ] . it is found that the central conclusion of mcclain et al . [ 12 ] is robust , and that gastropod colonists of the deep - sea benthos do indeed exhibit island - rule - like evolution .

part a shows how different tests of the ‘island rule’ can give qualitatively different results . “deep - sea” species were defined as those with a depth range midpoint > 200m , and all other species defined as “shallow - water” . the ordinary - least - squares regression ( dashed line ) differs significantly from the 1∶1 line of the null ( dotted line ) , but the standardized - major - axis regression ( solid line ) shows no significant departure . part b shows a less ambiguous case : “deep - sea” species are those never observed above 400m , and “shallow - water” species those never observed below 200m ; body sizes are within - genus means , taking equal numbers of deep - and shallow - water species in each genus .

the body sizes of deep - sea gastropods are plotted against those of their shallow - water congeners . “shallow - water” species were never observed below 200m , and “deep - sea” species never observed above depths of a : 200m , b : 400m and c : 600m . separate standardized - major - axis regression lines are shown for the neogastropoda ( black points ) and all other groups ( grey points ) . the dotted line is the 1∶1 expected under the null . genera with fewer than two deep and two shallow species were excluded .

similarly , predator release is a particularly plausible explanation of the vertebrate island rule [ 1 ] , [ 4 ] , [ 6 ] , [ 11 ] ; this is partly because it can naturally account for both dwarfism and gigantism ( by assuming that large and small body sizes evolve as alternative strategies for predator avoidance ) , and partly because predator release is so clearly implicated in other unusual characteristics of island endemics ( such as tameness ) [ 37 ] , [ 38 ] . but there is little evidence that reduced predation characterises the deep - sea [ 12 ] , [ 14 ] , and indeed there is direct evidence of substantial predation acting on deep - sea gastropods [ 12 ] , [ 39 ] – [ 41 ] . the gastropod results therefore argue against the predator release hypothesis as a general explanation of the island rule [ 12 ] .

we are therefore still far from understanding the causes of the patterns observed – and particularly the roles of inter - and intra - specific competition [ 3 ] , [ 4 ] , [ 11 ] , [ 12 ] . a detailed clarification of where the pattern does and does not hold will be an important step toward achieving this goal [ 4 ] , [ 12 ] , [ 19 ] , [ 20 ] .

after more than 2 years of preparations , the diatombase portal is now officially launched . . . .

last week - on may 30 and 31st – 8 thematic experts on talitridae came together for the first time during a lifewatch - worms sponsored workshop . the workshop took place at the hellenic centre for marine research in crete , where it was organized back - to - back with the 8th international sandy beaches symposium ( isbs ) . the group focused on identifying relevant traits for the talitridae , and adding this data through the amphipoda species database . . . .

on 23 april 2018 , a number of editors of the world register of introduced species ( wrims ) started a three day workshop in the flanders marine institute ( vliz ) . these three days were used to evaluate , complete and improve the content of this worms thematic register ( tsd ) . . . .

the 2nd worms early career researchers and 3rd worms achievement award were granted respectively to françois le coze and geoff read . congratulations ! . . .

in 2018 , to celebrate a decade of worms ' existence , it was decided to compile a list of our top marine species , both for 2017 and for the previous decade . . . .

the scleractinian corals are now accessible though their own list portal . this world list contains over 1 500 accepted names of extant species and is one of the most complete existing resources for scleractinian taxa . . .

historical collections of biological specimens are potentially rich sources of data for contemporary researchers . however , many technical issues have to be addressed in order to make these collections widely available . this paper reports on a qualitative study of historical and current data practices at the academy of natural sciences , philadelphia , which is seeking wider understanding of the historical dimensions of specimen metadata , in order to support migration to more global standards . a detailed case study of a single specimen shows how that specimen has been described in multiple ways and in multiple locations within the academy , and the historically complex nature of the data and metadata contained in these descriptions .

murex salmo wood , 1828 and fasciolaria granosa broderip , 1832 are shown to be conspecific . the first available name for a different species often identified as pleuroploca or fasciolaria salmo is fasciolaria valenciennesii kiener , 1840 , which deshayes ( 1843 ) incorrectly treated as a synonym of p . salmo . in the last several decades , authors who presumably intended to use the name pleuroploca salmo sensu deshayes have inadvertently illustrated true p . salmo . since usage of the names is not consistent , we follow strict priority and synonymize fasciolaria granosa with murex salmo . the currently valid names for these species are granolaria salmo ( wood , 1828 ) and granolaria valenciennesii ( kiener , 1840 ) .

a central aim of biodiversity informatics initiatives is the global aggregation of biodiversity data . this work depends significantly on the translation of local data and metadata into wider global standards . while this is often considered to be primarily a technical task , there are also organizational factors to consider . in this paper , we use a communities of practice approach to argue that data and metadata in individual departments and institutions has often adapted over time to meet local organizational contexts , and that digitization workflows need to account for and capture the historical dimensions of collections , to support productive data migration . as part of this work , the central role of curators ' and managers ' practical and everyday knowledge of their collections is emphasized .
