Description of Byspira polyomma n.sp. (Annelida:Sabellidae):a probabile introduction to The Netherland
No full textBispira polyomma sp. nov. is described. The taxon was recently found on the SW coast of The Netherlands (NE Atlantic), and
could not be referred to as any previously described species of the genus Bispira. The area has been thoroughly investigated in
the past, therefore we hypothesize the species is a new introduction to The Netherlands. The tubeworm is able to settle massively
on all kinds of hard substrates, is eurythermal and able to withstand slight pollution, and therefore wider dispersal is a possibility
to reckon with. For this reason we give a taxonomic species description even though the genus needs further revision. Presently
the taxon has been observed only near Yerseke, a centre of shellfish culture and trade with a marina. The taxon was found in
2010. Subsequent surveys revealed a very dense population had developed in 2011, with the presence of small individuals in
summer 2011 suggesting successful reproduction
Freshwater immersion as a method to remove Urosalpinx cinerea and Ocinebrellus inornatus from mussel seed
No full textA simple experiment to test whether immersion in freshwater for ≤24 hours would kill two oyster drills, Urosalpinx cinerea and Ocinebrellus inornatus was conducted to test the proposal of using freshwater to rid mussel seed of the drills before translocation from the Oosterschelde to the Wadden Sea. Freshwater failed to kill any individuals of either species, but did cause them to detach from the substratum for the entire time of immersion. Immersion in freshwater is therefore not recommended as a method to control the drills. Rinsing in freshwater may be an option to remove the drills without killing them, but has no guarantee of 100 % success. Further investigation may result in the development of other treatment options
Naamlijst van de mariene snoerwormen van Nederland, met vijf nieuwe soorten (Nemertea)
No full textWe present an updated list of marine nemertean species from the Netherlands. Eleven species not mentioned in the previous list (Faasse 2003) are briefly discussed, and we report five newrecords for the Netherlands, Cerebratulus spec. Riseriellus occultus, Amphiporus bioculatus,Psammamphiporus elongates and Tetrastemma melanocephalum These are all species of soft sediments which are not identified to the species level in standard monitoring programmes,due to fixation in formol. Identification using live nemerteans is recommended. As microbenthic predators with a relatively high consumption rate, they may play significant roles infood webs. All nemertean species are probably under-recorded internationally

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
