During a study of fauna associated with shallow-water Zostera (Zosterella) noltei bed from the southern part Romanian Black Sea coast, among identified material collected in 2015, syllid polychaete belonging to subfamily Exogoninae, Sphaerosyllis taylori Perkins, 1981, represents new record for Sea. Re-examination available specimens previously as bulbosa Southern, 1914 revealed that they belong an unknown species, described herein pontica sp. nov. The species is characterized by median...
In order to clarify taxonomic problems relating the identity of Scolelepis (Scolelepis) specimens from Black Sea, identified material was compared with cirratulus (Delle Chiaje, 1829) Mediterranean, S. squamata (Abildgaard, in O.F. Müller, 1806) North Sea and Atlantic coast Spain, syntypes mesnili (Bellan & Lagardère, 1971) France. The examination a large number (both juveniles adults) reveals that currently accepted morphological differences distinguishing all species show size-related...
Ecosystem engineers create habitat and provide conditions otherwise unavailable for the development of diverse communities. In marine soft-bottoms in particular, biodiversity sustained by a matrix relatively uniform sediments can be drastically enhanced presence ecosystem such as seagrasses. Unfortunately, influence seagrass meadows on diversity surrounding is often unrecognized spite its importance, especially coastlines exposed to multiple sources pollution. This study examined composition...
The identity of Scolelepis squamata (O.F. Müller, 1806 O. F., Abildgaard, P. C., Vahl, M., Holten, J. S., & Rathke, (1806). Zoologia Danica seu Animalium Daniae et Norvegiae rariorum ac minus notorum. Descriptiones historia (Vol. 4. Volume Atlas). N. Christensen. [Google Scholar]) (Spionidae) has long been under debate. For clarification this problem a collection specimens at the type locality species, island Helgoland (North Sea) and in particular Dunes, undertaken. Based on morphological...
In this study we present a list of invasive/potential invasive alien species in the East and South European Network for Invasive Alien Species (ESENIAS) countries with marine borders. The were classified according to existing literature experts’ judgment, as established, casual, expected. Finally, factsheets compiled ten high importance based on their expanding/invading character. Of 160 comprising list, 149 already ESENIAS countries, while eleven either Mediterranean or other Seas, likely...
A survey conducted in inshore waters along the Romanian coast of Black Sea from 1994 to 2000, yielded 24 polychaete species belonging 10 families as follows: Polynoidae (2), Phyllodocidae Syllidae (3), Nereididae (5), Spionidae Capitellidae Nerillidae (1), Sabellidae Serpulidae and Spirorbidae (1). Polydora websteri (Hartman, 1943) is a new record for Mediterranean region. P. cornuta (Bose, 1802) first recorded Sea. Additionally, two other species, namely Harmothoe imbricata (Linnaeus, 1767)...
The taxonomic, morphological, biological, behavioural and ecological characteristics of three species spionid poly-chaetes from the Black Sea belonging to Polydora-complex are summarised discussed on basis author′scollections along Romanian coasts as well material other parts Sea. It is apparent that at least twospecies have been included under name′Polydora ciliata′ in literature. All previous records Polydorathat bore into calcareous substrates most likely Polydora websteri. individuals...
Until the beginning of 21st century, famous medicinal leech was thought to be represented by only one species, Hirudo medicinalis. However, recent publications have demonstrated that under name, at least five different species leeches were hidden. During last decade, biogeography Western-Palaearctic has begun unravel, untangling their diversity in practically all Europe, except for its westernmost peninsula, Iberia. medicinalis been repeatedly reported from Iberia, but those records...
This study presents the first data on distribution of Mediterranean medicinal leech Hirudo verbana in Romania, as well molecular characterization Romanian populations, using mitochondrial DNA markers. In total, 133 specimens from 19 populations Romania were surveyed for COI and 12S Available GenBank sequences other localities throughout Europe included to place a broader phylogeographical context. The H. samples belong 23 haplotypes, 4 which are previously known Serbia Ukraine, while...
Abstract Populations of Alitta (=Neanthes) succinea (Frey and Leuckart, 1847) collected from two closely situated locations on the Romanian coast Black Sea were analysed March 2007 to May 2008 in order elucidate their population dynamics genetics. The mean density was 655 ind. m−2, presenting peaks, first June with 950 m−2 second November 1633 m−2. biomass over entire period survey 4.33 g dry weight (DW) a minimum 1.15 DW September maximum 8.08 2007. decrease winter is determined by...
Exposure to a variety of anthropogenic stressors has prompted the creation growing number marine protected areas (MPAs). Unfortunately, long-term changes in both sources stress and extent or operation MPAs have also occurred, at pace that is often faster than research trying understand consequences those changes. This study addresses this challenge by focusing on two located southern Romanian Black Sea, namely Cape Tuzla Mangalia Sulfur springs. Using 95 seafloor samples collected over...
There are many taxonomic problems in polychaete species names and solving confusing or inadequate procedures is both time-demanding extremely important. Our objective this contribution was to analyse what the current situation for Nereis falsa de Quatrefages, 1866; it based upon pulsatoria? Rathke, 1837 from Black Sea, currently regarded as having a very wide distribution. The has been collected different benthic substrates even can be found on floating objects marine turtles. recorded...
The spionid genus Scolelepis is commonly divided into the subgenera (s. str.) and Parascolelepis. In Black Sea, two species ascribed to subgenus Parascolelepis have been reported so far – tridentata cantabra. Both are quite rare when found usually difficult identify because of their fragility. To ascertain identity specimens from type-series S. non-type cantabra were examined. examination Sea identified as revealed that they differ nominal in several characters. Therefore, described herein...
Scolelepis neglecta Surugiu, 2016 is a polychaete species that was described from the Cantabrian coast of Asturias (northern Spain) based only on anterior fragments museum collections. Recently collected live material S. intertidal muddy sand flats Villaviciosa estuary (Asturias, Bay Biscay, northern Spain), has enabled us to report some new, previously unknown morphological characters, such as shape pygidium, shape, number and distribution notopodial hooded hooks, assess validity by means...
In this study we analyzed at a submeso-geographic scale (2 km) the genetic diversity of two sub-populations Platynereis dumerilii and correlated with physical characteristics marine currents along western Black Sea coast. For purpose, developed set 13 new polymorphic microsatellite markers used them to assess differentiation, as well bi-directional migration rates between studied sub-populations. We also computed Peclet number (Pe) an indicator relative effect advection eddy diffusion on...
Abstract An isolated, but persistent population of the European medicinal leech Hirudo medicinalis Linnaeus, 1758 is reported from “Mestecănișul de la Reci” Natural Reserve (ROSCI0111, Covasna County), representing first confirmed record this species in Romania. Information regarding habitat characteristics, main diagnostic features and protection status presented.
