Opis:: The marine species richness (MSR) recorded in 159 sandy beach surveys was analysed in relation to beach width (W). MSR is the number of macrobenthic species collected in a standard intertidal transect survey, excluding insects. Beach width (W) was estimated by dividing the spring tide range [m] by the beach face slope, to give a value in [m]. The relationship between MSR and W was best described by a semilog (exponential) model, which was highly significant: MSR = −5.2+ 10.8 logW. The fit of a power model (MSR = cWz) was also significant. The steep slope of the curve for a power model (z = 0.49) suggests that beaches function as isolated rather than contiguous habitats and that the nature of the habitat becomes more benign as beaches widen. There are some latitudinal effects, with tropical beaches displaying a higher species-area relationship for any beach width than other regions.

Opis:: Ten new species of myxosporeans found from marine fishes were collected from coastal waters off the Yellow Sea in China: Sphaerospora sebasta sp. n. coelozoic in the gall bladder of Sebastes schlegeli, Ceratomyxa hemitriptera sp. n. coelozoic in the gall bladder of Hemitripterus villosus, Ceratomyxa kareus sp. n. coelozoic in the gall bladders of Kareius bicoloratus and Zebrias zebra, Ceratomyxa lateolabrax sp. n. and Ceratomyxa lomi sp. n. coelozoic in the gall bladder of Lateolabrax japonicus, Ceratomyxa qingdaoensis sp. n. coelozoic in the urinary bladder of Argyrosomus argentatus, Ceratomyxa saurida sp. n. coelozoic in the gall bladder of Saurida elongata, Ceratomyxa sebastisca sp. n. coelozoic in the gall bladder of Sebastiscus sp., Ceratomyxa simplex sp. n. coelozoic in the gall bladder of Chirolophis japonicus and Ceratomyxa triacantha sp. n. coelozoic in the gall bladder and bile of Triacanthus brevirostris. All those forms were described in a book chapter cited as “known forms” several years ago, but have never been formally established as new taxa which are thus officially reported here. The present contribution only provided the morphology and geographic distribution of these organisms.

Tematy:: Cyrtophorida, infraciliature, marine ciliates, new species, taxonomy
Opis:: The present work investigates the living morphology and infraciliature of three marine cyrtophorid ciliates, which were isolated from Qingdao, China. Compared with its congeners, Orthotrochilia sinica spec. nov. can be distinguished by a combination of features: body slender and elliptical in outline, size about 50–60 × 20–25 μm in vivo, 18–21 somatic kineties, the length of the left perioral kinety treble the length of the right one, two ventrally located contractile vacuoles on the right side, and 25–32 nematodesmal rods. Based on current observations and the previous description, the diagnosis of Trochilioides tenuis (Deroux, 1976) Chen et al. 2011 is improved: cell size 30–40 × 20–35 μm in vivo, oval shaped in outline; consistently three right kineties, four left kineties and seven postoral kineties; a single contractile vacuole; marine habitat. A second species of Trochilioides, T. recta (Kahl, 1923) Chen et al. 2011 is re-described based on a Chinese population. Furthermore, a key to the identification of species of the genus Trochilioides whose infraciliature data are available is supplied, and Chlamydonyx trivialis (Fenchel, 1965) comb. nov. [basionym: Trochilioides trivialis Fenchel, 1965] is suggested.

Opis:: Three marine peritrichous ciliates, Zoothamnium alrasheidi spec. nov., Z. marinum Kahl, 1933 and Z. vermicola Precht, 1935, were isolated from littoral areas near Qingdao, China. The living morphology, infraciliature and silverline system were studied in living and silver-impregnated specimens. Zoothamnium alrasheidi is distinguished from its congeners by the giant, leaf-shaped colony, the differentiation of zooids, the structure of the infundibular polykineties and in having 57–75 silverlines between the oral area and the trochal band and 24–42 between the trochal band and the scopula. Zoothamnium marinum and Z. vermicola are reported for the first time in over 70 years. Each was identified by its zooid shape and size, colony shape, the branching pattern of its stalk and its marine habitat. As a result of the present study, additional features for characterizing these species now include the structure of infundibular polykinety 3 and the number of silverlines between the aboral trochal band and (a) the scopula, and (b) the peristomial lip. Redescriptions and improved diagnoses of both species are supplied based on the Chinese populations.

Opis:: During faunistic studies of ciliates in coastal waters of Daya Bay and Bohai Bay, China, two previously unknown ciliates were discovered and investigated using standard taxonomic methods. Morphological comparative analyses revealed that they represent two novel species in the genus Chaenea. Chaenea paucistriata spec. nov. can be distinguished from its congeners by the following traits: body length in vivo about 180–250 µm; eight somatic kineties; dorsal brush rows 1–4 consisting of three, five, seven, and two dikinetids, respectively; rod-like extrusomes, 8 µm long; 63–94 macronuclei; cortical granules minute and colourless. Chaenea sinica spec. nov. differs from its congeners in having: body length in vivo about 140–240 µm; 17–21 somatic kineties; dorsal brush rows 1–4 consisting of 3–7, 10 or 11, 11–13, and 3–6 dikinetids, respectively; rod-like extrusomes about 6–8 µm long; 71–164 macronuclei. A key is presented to assist the identification of all Chaenea species.

Opis:: The morphology, morphogenesis and infraciliature of two marine euplotid ciliates, Euplotes dammamensis n. sp. and Euplotes balteatus (Dujardin, 1841) Kahl, 1932, isolated from a sandy beach of the Arabian Gulf, Saudi Arabia, were investigated using observations in vivo and protargol-impregnation methods. Euplotes dammamensis n. sp. is characterized by a combination of features including its huge body size (100–170 × 80–120 μm), 10 conspicuous dorsal ridges, 10 normal-sized frontoventral and two marginal cirri, and 11 dorsal kineties. Euplotes balteatus is mainly characterized by 10 frontoventral, two caudal, and two left marginal cirri, 7–10 dorsal kineties and 5–7 prominent dorsal ridges as well as double-eurystomus silverline system. The small subunit rRNA (SSU-rRNA) gene sequences were determined for both species and phylogenetic analyses based on these data indicated that E. dammamensis is most closely related to E. parabalteatus Jiang et al., 2010, and E. balteatus clusters with E. plicatum Valbonesi et al., 1997, E. orientalis Jiang et al., 2010, and E. bisulcatus Kahl, 1932.

Opis:: Eight marine scuticociliates, Pseudoplatynematum denticulatum (Kahl, 1933) nov. comb., Protocyclidium sinica nov. spec., Histiobalantium marinum Kahl, 1933, Porpostoma notata Möbius, 1888, Philaster hiatti Thompson, 1969, Parauronema longum Song, 1995, Uronemella parafilificum Gong et al., 2007, and Paranophrys magna Borror, 1972, collected from Chinese coastal waters, were investigated using live observations and silver impregnation methods. Investigations of a Chinese population of Platynematum denticulatum (Kahl, 1933) reveal that it has a highly strengthened pellicle and distinct spines and thus corresponds well with the definition of Pseudoplatynematum Bock, 1952. A new combination, Pseudoplatynematum denticulatum (Kahl, 1933) nov. comb., is therefore proposed and an improved species diagnosis is supplied. Protocyclidium sinica nov. spec. is characterized by: small body size with buccal field approximately 60% of body length; extrusomes present; 13 or 14 somatic kineties; somatic kinety 1 comprising approximately 24 densely arranged kinetids; somatic kinety n shortened posteriorly; single macronucleus. Additional information is documented on the morphology of six other species of scuticociliates based on the China populations.

Opis:: The fast development of marine transport causes a lot of environmental concerns connected with possible accidents of ships transporting hazardous cargoes as well as oil pollution coming from an exploitation of engine rooms. Moreover, a significant problem is connected with a ballast water handling. The use of ballast water is necessary for the safe movement of large ships. Namely, in maritime transport a ship unloading causes a reduction in its draft - it is a cause of lower steering or even completely prevents the safe movement of the ship. Therefore, in place of the discharged freight the ballast water is collected (often just during the unloading). This water is pumped out from a ship at the site of re-loading. However, this implies the risk of transportation of living organisms over large distances, which (if at the point of discharge of ballast water will find suitable conditions) can become invasive species. Because of the risks involved in carriage of these organisms, the International Maritime Organization (IMO) has developed rigorous standards for permissible amounts of organisms in the discharged ballast water. A number of methods of biological neutralization of ballast water, that meet the requirements of the IMO, have been developed. The topic of this paper is to review currently used methods of neutralization of ballast water. We consider clearing of ballast water from point of view of physics, especially by using electromagnetic radiation and ultrasonic waves.

Opis:: The morphology and taxonomy of two new and two poorly known ciliate species of Ancistrum, found in the mantle cavity (mainly on gills) of marine molluscs from culture beds and pools along the Chinese coast of the Yellow Sea, were investigated using living observation and silver impregnation. Ancistrum haliotis n. sp. was isolated from the abalone Haliotis discus hannai Ino, A. crassum Fenchel, 1965 from the purple clam Saxidomus purpuratus (Sowerby), A. acutum n. sp. from the surf clam Mactra veneriformis Reeve, and A. japonicum Uyemura, 1937 from both the venus clam Cyclina sinensis (Gmelin) and from Dosinia japonica (Reeve). Ancistrum haliotis differs from its most similar relative A. mytili (Quennerstedt, 1867) by the body outline (anterior portion narrower vs. wider than the posterior portion), the macronuclear shape (broadly ellipsoidal vs. reniform or sausage-like), and by having fewer somatic kineties (28–32 vs. usually more than >40). Ancistrum crassum is characterized by the naked area at the apical end of the cell, the relatively short buccal field occupying about two thirds of the body length, and the posterior-dorsal cone-shaped prolongation. Ancistrum acutum n. sp. and A. japonicum are almost identical in morphometry, but differ distinctly in the live morphology (anterior end pointed and posterior end rounded vs. anterior end narrowly rounded and posterior-dorsal end protruded) and ciliary pattern (all right-side kineties extend to posterior body end vs. all right-side kineties excluding somatic kinety 1 distinctly shortened posteriad, forming a glabrous zone). We neotypify Ancistrum japonicum and discuss the taxonomic status of the four species. Based on an evaluation of all nominal species of Ancistrum and Ancistrumina, we recognize nine valid species of Ancistrum and provide a tabular guide to their identification. Fenchelia Raabe, 1970 is regarded as a junior synonym of Ancistrum Maupas, 1883. We synonymize Ancistrumina nucellae Khan, 1970 with Ancistrum japonicum Uyemura, 1937 and Ancistrum edajimanum Oishi, 1978 with A. crassum Fenchel, 1965.

The present review deals with variety, sugar specificity and the medicinal importance of lectins from freshwater and marine invertebrates. The potent medicinal usage of the various types of the lectins from freshwater and marine non-chordates, which are comparatively well studied and compiled. Various literatures survey revealed that the lectin isolated in recent past from the freshwater species majorly from mollusca and arthropods (crustacean) etc. and also from marine sources of phylum porifera, cnidaria, annelida, arthropoda, mollusca and echinodermata could be rich sources of medicinal properties having remedial measures to bacterial infection, inflammatory disorders, cancer, mitogenic effect and antigen defence. The present study will be a database development to support global drug discovery researches on several types of lectins from freshwater and marine organisms for academicians, researchers and medicine manufacturers having therapeutic approaches for mankind by natural ingredients.

Opis:: There is only one survey on the species of amphibians and their parasites from Okrika, Rivers State, Nigeria. Therefore, this research was carried out with the intention of exploring the city for more amphibian species and also reporting on the parasites infecting them. Visual acoustic and survey methods were employed in surveying the study location, Greame Ama, for the period of September to November, 2018, and standard parasitological techniques were adopted. In comparison with the earlier research, fewer amphibian species were encountered: Sclerophrys maculata, Hoplobatrachus occipitalis, Ptychadena pumilio and P. mascareniensis. However, new parasite species were found: Diplodiscus fischthalicus, Metahaematoloechus exoterorchis and Cephalochlamys compactus. A higher prevalence of infection (96.6%) was reported here than in the earlier report. Of the nine parasite species reported in this research, three have direct transmission routes (Rhabdias sp., Cosmocerca ornata, Cylindrotaenia jaegerskioeldii), while six (Raillietiella sp., Cephalochlamys compactus, Mesocoelium monodi, D. fischthalicus, Metahaematoloechus exoterorchis and ascaridida larva) are transmitted by ingestion of either insect or gastropod intermediate hosts. However, the most prevalent species were those with direct transmission routes as is common with more terrestrial amphibian species. It is concluded that amphibian diversity in Okrika is low but more parasite species are likely to be reported with more surveys.

Opis:: Biofouling is called “lessons from nature”. Currently, governments and industry spend more than 5.7 billion USD annually to control unwanted marine biofouling, aquatic flora and fauna on submerged construction leading to various technical, economical, and ecological problems. In turn, the Baltic Sea is defined as a “time machine” for the future coastal ocean, as processes occurring in the Baltic Sea are related to future changes. Our study describes the biofouling community at 12 sites located at different depths on the legs of the “Baltic Beta” oil platform that resulted in finding a maximum of 1,300 individuals on 400 cm2. We analyzed: spatial distribution of dominant marine organisms living on a steel platform surface, their abundance and mass. Our work showed no significant difference in the benthic samples mass among different depths or cardinal directions of the rig columns. Our research can help to predict offshore biofouling on other devices in the Baltic Sea, to control invasive species and to estimate environmental load.
Biofouling potocznie nazywany jest "lekcją od natury”. Obecnie rządy i przemysł wydają ponad 5,7 miliarda USD rocznie, aby kontrolować biofouling w morzach i oceanach, który stanowi nagromadzenie fauny i flory na podwodnych konstrukcjach, co w efekcie prowadzi do różnych problemów technicznych i ekologicznych. Natomiast Morze Bałtyckie jest definiowane jako "wehikuł czasu”, ponieważ zmiany w nim zachodzące aktualnie stanowią odzwierciedlenie przyszłych zmian środowiskowych w innych regionach morskich i oceanicznych. Nasze badania przedstawiają zbiorowiska makrobentosu pobranego z 12 lokalizacji położonych na różnych głębokościach nóg platformy wiertniczej "Baltic Beta”. Zidentyfikowaliśmy maksymalnie do 1300 osobników na 400 cm2. Przeanalizowaliśmy: przestrzenne rozmieszczenie dominujących organizmów morskich żyjących na stalowej powierzchni platformy, ich liczebność i masę. Badania nie wykazały znaczących różnic w masie próbek bentosowych pomiędzy różnymi głębokościami i kierunkami geograficznymi. Nasze badania mogą pomóc w przewidywaniu rozwoju biofoulingu na innych urządzeniach w Morzu Bałtyckim, identyfikacji występowania gatunków inwazyjnych i oszacowaniu obciążenia konstrukcji podwodnych.

Opis:: In June 2005 metaplantation of Eryngium maritimum and Epipactis atrorubens, from the build area of the Gdańsk Container Terminal into Sobieszewska Island was carried out. The reason for that immediate action was the unreliable report of the influence of investment on the environment, in which the mentioned above species have not been included. Metaplantation was conducted during one day time, by 21 volunteers. Altogether, 146 individuals of Sea Holly and 184 ones of Dark Red Helleborine have been translocated. Detailed measurements of each individual were made. On the new site, all planted individuals were permanently labelled. The newly constituted populations have been taken under monitoring. With regard to species of special concern, metaplantation of threatened populations seems to be the most beneficial form of nature compensation expected from the investors. Still, there are no unambiguous procedures for its executing.
Rozwoj gospodarczy i związana z tym nasilająca się antropopresja powodują istotne przekształcenia środowiska przyrodniczego na rożnych poziomach jego organizacji: ekosystemalnym, biocenotycznym i gatunkowym. Zgodnie z obowiązującą w Polsce polityką zrównoważonego rozwoju zmiany te, często nieuniknione, powinny być poprzedzone działaniami minimalizującymi ich skutki. W związku z tym podejmowane są działania czynnej ochrony przyrody. Jedną z tych metod, która dotyczy ochrony ginących i zagrożonych gatunków roślin, jest metaplantacja. Według „Poradnika ochrony siedlisk i gatunków Natura 2000” (Sudnik- Wojcikowska i Stebel 2004) metaplantacja to: „metoda ochrony gatunków ginących, polegająca na przenoszeniu roślin i zwierząt z zagrożonych stanowisk naturalnych na stanowiska zastępcze”. W czerwcu 2005 roku przeprowadzona została metaplantacja populacji Eryngium maritimum i Epipactis atrorubens z terenu budowy terminalu kontenerowego Portu Północnego w Gdańsku na Wyspę Sobieszewską. Przygotowanie i przeprowadzenie metaplantacji musiało odbyć się bardzo szybko ze względu na rozpoczęte już prace budowlane. Tak późne rozpoczęcie starań o uratowanie lokalnych populacji obu gatunków wynikało z nierzetelnie sporządzonego raportu oddziaływania inwestycji na środowisko, w którym wyżej wymienione gatunki nie zostały uwzględnione. Metaplantację przeprowadzono w ciągu jednego dnia, a wzięło w niej udział 21 wolontariuszy. Ogółem przeniesiono 146 okazów mikołajka nadmorskiego i 184 kruszczyka rdzawoczerwonego. Wykonano szczegółowe pomiary każdego przenoszonego okazu. Na nowym stanowisku posadzono i trwale oznakowano wszystkie przeniesione rośliny. Nowo powstałe populacje objęte zostały monitoringiem. W przypadku gatunków szczególnej troski metaplantacja zagrożonych populacji wydaje się najkorzystniejszą formą kompensacji przyrodniczej, wymaganej od inwestorów. Nadal brak jest jednak jasno określonych procedur jej przeprowadzania.
