Abstract (sommario):

The recent unintentional creation of a bryozoan secondary homonym requires a change of name for the species affected. Gontar (2009) established the new monotypic genus Paulina (order Cyclostomata), with type species Paulina taylori, for a small, ramifying uniserial species of Oncousoeciidae from the upper shelf of the Pacific coast of the middle Kurile Islands, Russia. Paulina Gontar, 2009 is preoccupied by Paulina Grigelis, 1977 (Protozoa, Foraminifera). Paulella nom. nov. (gender feminine) is here proposed as a replacement genus, resulting in the new combination Paulella taylori (Gontar, 2009).

Abstract (sommario):

This work describes Bryozoa of the orders Cyclostomata and Ctenostomata found associated with polymetallic nodules collected by box-coring in the eastern part of the Russian exploration area of the Clarion-Clipperton Fracture Zone (CCFZ) under contract to Yuzhmorgeologiya. Scanning electron microscopic study of 358 cyclostome colonies and 14 ctenostome colonies from 4510–5280 m depth has resulted in the recognition of two new species of Ctenostomata, and 14 new species, nine new genera and two new families of Cyclostomata; three additional species of Cyclostomata are left in open nomenclature pending the discovery of missing reproductive characters. The taxonomic novelty is thus notable. One of the new Ctenostomata represents the first living example of the previously monotypic Late Cretaceous genus Pierrella. Twelve of the new cyclostome taxa have well-developed gonozooids, indicating that embryonic cloning (polyembryony) is normal in this deep-sea environment. On the other hand, one indeterminate tubuliporine and two rectangulates have dimorphic peristomes. In the latter two cases, enough mature colonies were found to suggest that this feature is normal, and that the dimorphic zooids are possibly female—in other words, capacious incubation chambers are apparently lacking, and therefore polyembryony would also be lacking or reduced. In one of these species, evidence is presented to suggest that the ancestrular zooid can reproduce precociously. Of the species reported here, only one has previously been found outside the exploration area, highlighting both the limited knowledge we have of bryozoans in the deep Pacific and/or a fauna that is largely endemic to the nodule environment. An additional 31 species of Cheilostomata have also been discovered that will be described in a subsequent publication. Most bryozoans are macrofaunal-sized, so are both inadequately determinable and overlooked in images obtained by remotely operated vehicles; yet, with 50 species, Bryozoa is the most speciose sessile macrofaunal phylum on the nodules. Nodules constitute hard substrata in an area otherwise mostly inhospitable for Bryozoa, hence mining would lead to loss of critical habitat. Further, as suspension-feeders, bryozoans are highly susceptible to smothering by suspended sediment, and non-mined areas closely adjacent to extraction zones would likely also be affected and their associated bryozoan fauna obliterated. More data are required on the distribution of the CCFZ bryozoan species elsewhere in the east Central Pacific to determine if mining would lead to local taxon extirpation or global extinction at both low and high taxonomic levels.

Abstract (sommario):

Mit der Methode der Elektrofischerei wurde 1983 und 1984 der Fischbestand in Fließgewässern der Senne (Ostwestfalen, Bundesrepublik Deutschland) untersucht. Daneben wurden die Gewässerstruktur, die Gewässergüte sowie die Verbreitung und Häufigkeit der Fischnährtierfauna (Makroinvertebratenfauna) ermittelt. Die Fischfauna der Senne umfaßt 1 Rundmäulerart (Cyclostomata) und 23 Fischarten (Osteichthyes), wovon 20 zum autochthonen Fischbestand zu zählen sind. 58% aller nachgewiesenen Arten müssen als im Bestand gefährdet eingestuft werden. In den früher fischreichen Gewässern der Senne wurde nur noch in wenigen Gewässerstrecken eine der fischereilichen Zonierung entsprechende Fischfauna gefunden. Ursache sind neben der meist schlechten Gewässergüte Ausbau- und Regulierungsmaßnahmen.

Abstract (sommario):

One specimen of hag fish Eptatretus sp. was collected from the Arabian Sea, off Kerala coast of India at 500-600 m depth. The phylogenetic analysis using the sequence of mitochondrial gene cytochrome oxidase C (CO1) suggested the Eptatretus sp. collected from India is distinct from all other species where sequence data is available and P ID (Liberal) for Eptatretus sp. collected from India is 0.96, indicating a high probability that an unknown member of the putative species would be correctly identified as a member once more specimens are collected.

Abstract (sommario):

Zooids of cheilostome bryozoans are on average substantially more robust than are zooids of cyclostome bryozoans. The differences include greater number, length, and cross-sectional area of tentacles, plus a more extensively developed funiculus. Median values for mouth size and cilia-generated feeding current velocity are greater for cheilostomes than for cyclostomes so that cheilostomes have the potential for greater intake of nutrient energy per unit time, which may explain their apparently higher growth rates. For unit area of substrate occupied, the Cheilostomata (Class Gymnolaemata; members of the post-Paleozoic fauna) contain greater biomass and apparently generate greater energy flow than do the Cyclostomata, which are the only extant order of the Class Stenolaemata (characteristic of the Paleozoic fauna).

Abstract (sommario):

A rich fauna of Bryozoa from the Lower Pliocene of the Maronia district (location of Hagios loannis) had been studied. 47 species have been indentified belonging to the Cyclostomata (16) and Cheilostomata (31). This study allows to precise - based on the Foraminifers - the distribution of Bryozoans in this area of the South- East Mediterranean. Based on the zoarial forms, the bathymetry, the temperature and the bottoms, where some species live yet now, we attempt to give a reconstruction of the paleoenvironments. The Lower Pliocene age is based on the stratigraphie distribution of the following Foraminifers: Amphistegina lessonii, Bolivina antiqua, μBulimina cf. minima, Cibicides refiilgens, Globigerinoides extremus, Globigerinoides nepenthes, Globigerinella pseudobesa, Globulina fissicosta, Heterolepa dertonensis, Neogloboquatrina ci.acostaensis, Rectuvigerina siphogenerinoides, Sphaeroidinellopsis seminulina.

Solo 10 especies son exclusivas del Holoceno; 35 se han encontrado en el Neógeno y 10 en el Paleógeno. Se describen las especies más significativas. Por otra parte, las asociaciones faunísticas encontradas en las diversas muestras indican en la mayoría de casos un medio de aguas poco profundas y con tasas muy bajas de sedimentación.

Abstract (sommario):

Reticulate Hornera reteramae (Bryozoa, order Cyclostomata) have been discovered as free-lying, lyre-shaped colonies in the Castle Hayne Limestone (Eocene) in North Carolina. These specimens represent a striking instance of homeomorphy in colony form with the Late Mississippian genera Lyropora and Lyroporella of the order Fenestrata.Bryozoans with reticulate growth habit most commonly develop upright colonies. Living representatives generally grow in quiet environments or microenvironments, and fossils are generally found in situ in quiet-water deposits. However, lyre-shaped Hornera reteramae occur in skeletal packstones inferred to have been deposited in a moderate-energy, shallow, open shelf environment near normal wave base. Upper Mississippian lyre-shaped colonies are preserved in skeletal packstones and grainstones in localized channels or on upper surfaces of low-angle cross-bedded sheets interpreted as high-energy, marine shoal deposits. Modification of the reticulate growth habit to low, peripherally weighted, free-lying structures apparently allowed invasion of higher energy sand bottoms, both in Mississippian and Eocene times.

Abstract (sommario):

AbstractThis is the first of two comprehensive taxonomic works on the early Miocene (ca. 23–20 Ma) bryozoan fauna associated with coral reefs from the Siamaná Formation, in the remote region of Cocinetas Basin in the La Guajira Peninsula, northern Colombia, southern Caribbean. Fifteen bryozoan species in 11 families are described, comprising two cyclostomes and 13 cheilostomes. Two cheilostome genera and seven species are new: Antropora guajirensis n. sp., Calpensia caribensis n. sp., Atoichos magnus n. gen. n. sp., Gymnophorella hadra n. gen. n. sp., Cribrilaria multicostata n. sp., Cribrilaria nixor n. sp., and Figularia bragai n. sp. Eight species are identified only at genus level and remain in open nomenclature. Of the species found, 27% have erect colonies and 73% encrusting colonies. Both types contributed to the reef framework and produced sediment. The observed bryozoan diversity was higher in the barrier reefs than in the lagoonal patch reefs.UUID: http://zoobank.org/5c8468ef-31b0-4e7e-ba93-60a2e2f30b76.

Abstract (sommario):

Transcription is known to be substage-specific in meiotic prophase I. If transcription is reactivated in the mid pachytene stage in mammals when synapsis is completed, then this process is observed in the zygotene stage in insects. The process of transcriptional reactivation has been studied in a small number of different taxa of invertebrates and vertebrates. Here, for the first time, we investigate synapsis and transcription in prophase I in the European river lamprey Lampetra fluviatilis (Petromyzontiformes, Cyclostomata), which is representative of jawless vertebrates that diverged from the main branch of vertebrates between 535 and 462 million years ago. We found that not all chromosomes complete synapsis in telomeric regions. Rounded structures were detected in chromatin and in some synaptonemal complexes, but their nature could not be determined conclusively. An analysis of RNA polymerase II distribution led to the conclusion that transcriptional reactivation in lamprey prophase I is not associated with the completion of chromosome synapsis. Monomethylated histone H3K4 is localized in meiotic chromatin throughout prophase I, and this pattern has not been previously detected in animals. Thus, the findings made it possible to identify synaptic and epigenetic patterns specific to this group and to expand knowledge about chromatin epigenetics in prophase I.
