Fish) of the Helford Estuary
HELFORD RIVER SURVEY A survey of the Pisces (Fish) of the Helford Estuary A Report to the Helford Voluntary Marine Conservation Area Group funded by the World Wide Fund for Nature U.K. and English Nature P A Gainey 1999 1 Summary The Helford Voluntary Marine Conservation Area (hereafter HVMCA) was designated in 1987 and since that time a series of surveys have been carried out to examine the flora and fauna present. In this study no less that eighty species of fish have been identified within the confines of the HVMCA. Many of the more common fish were found to be present in large numbers. Several species have been designated as nationally scarce whilst others are nationally rare and receive protection at varying levels. The estuary is obviously an important nursery for several species which are of economic importance. A full list of the fish species present and the protection some of them receive is given in the Appendices Nine species of fish have been recorded as new to the HVMCA.

Age Structure, Growth and Shell Form of Cerastoderma Glaucum (Bivalvia
Age structure, growth and shell form of Cerastoderma glaucum (Bivalvia: Cardiidae) from El Mellah lagoon, Algeria Lamia Bensaâd-Bendjedid, Saber Belhaoues, Asma Kerdoussi, Naouel Djebbari, Mardja Tahri, Mourad Bensouilah Laboratory of Ecobiology for Marine Environment and Coastlines, Faculty of Science, Badji Mokhtar University, Annaba 23000, Algeria. Corresponding author: L. Bensaâd-Benjedid, [email protected] Abstract. Cerastoderma glaucum (Poiret, 1789) the lagoon specialist cockle, represents one of the most abundant molluscs in El Mellah coastal lagoon (northeastern Algeria); several morphological and biological characteristics of this species were investigated over a period of 18 months (January 2014 to June 2015). Analysis of allometry and different morphometric indices indicate that this population tends to assume a globular shell shape which becomes elongated as the cockle grows. From length-frequency data examination using software FiSAT II and VONBIT for Excel, age was ranged from the first to the third year old, asymptotic length (L∞) was estimated to 48.061 mm and growth coefficient (K) was 0.71 -1 yr . The growth performance index (Φ′) and theoretical life span (tmax) were 3.21 and 4.23 yr respectively, total mortality rate (Z) obtained was 1.94 yr-1. Monthly variations in condition index were noticed, two sharp falls due spawning events were observed, the first spawning occurred between March and June and, the second one took place from August to October. The findings of the current study can be utilized to guide future research in various fields as pathology, biomonitoring and environmental management of this species. Key Words: Cerastoderma glaucum, shell shape, growth, Condition index, Algeria. -

An Adaptable Chromosome Preparation Methodology for Use In
Guo et al. BMC Biology (2018) 16:25 https://doi.org/10.1186/s12915-018-0497-4 METHODOLOGY ARTICLE Open Access An adaptable chromosome preparation methodology for use in invertebrate research organisms Longhua Guo1†, Alice Accorsi2,3†, Shuonan He2, Carlos Guerrero-Hernández2, Shamilene Sivagnanam4, Sean McKinney2, Matthew Gibson2 and Alejandro Sánchez Alvarado2,3* Abstract Background: The ability to efficiently visualize and manipulate chromosomes is fundamental to understanding the genome architecture of organisms. Conventional chromosome preparation protocols developed for mammalian cells and those relying on species-specific conditions are not suitable for many invertebrates. Hence, a simple and inexpensive chromosome preparation protocol, adaptable to multiple invertebrate species, is needed. Results: We optimized a chromosome preparation protocol and applied it to several planarian species (phylum Platyhelminthes), the freshwater apple snail Pomacea canaliculata (phylum Mollusca), and the starlet sea anemone Nematostella vectensis (phylum Cnidaria). We demonstrated that both mitotically active adult tissues and embryos can be used as sources of metaphase chromosomes, expanding the potential use of this technique to invertebrates lacking cell lines and/or with limited access to the complete life cycle. Simple hypotonic treatment with deionized water was sufficient for karyotyping; growing cells in culture was not necessary. The obtained karyotypes allowed the identification of differences in ploidy and chromosome architecture among -

(Marmara Sea) and Ecological Characteristics of Their Habitats
RESEARCH ARTICLE Eur J Biol 2017; 76(1): 20-5 Decapod Crustaceans in the Marmara Island (Marmara Sea) and Ecological Characteristics of Their Habitats Begum Ayfer, Husamettin Balkis, Aysegul Mulayim* Istanbul University, Faculty of Science, Department of Biology, Istanbul, Turkey Please cite this article as: Ayfer B, Balkis H, Mulayim A. Decapod Crustaceans in the Marmara Island (Marmara Sea) and Ecological Characteristics of Their Habitats. Eur J Biol 2017; 76(1): 20-5. ABSTRACT We have performed series of analyses to identify decapod crustaceans inhabiting the littoral zone of the Marmara Island and to study specific ecological characteristics of the habitat. Samples of decapod crustaceans species were collected from 12 stations (6 onshore, 6 offshore) on May 12-17, 2008 and November 17-22, 2008. A total of 17 species and 1199 specimens of decapod crustaceans were recorded. Eigth species (A. lacazei, N. norvegicus, P. bluteli, P. longimana, P. platycheles, D. pugilator, D. personata and L. vernalis) have been reported in the littoral zone of Marmara Island for the first time in this study. Also our study also sheds light on some ecological properties (temperature, salinity, dissolved oxygen) of the habitats of the species from the littoral zone of the Marmara Island.

The copyright holder for this preprint (which was not peer-reviewed) is the author/funder. All rights reserved. No reuse allowed without permission. Abstract Little is known about venom in young developmental stages of animals. The appearance of stinging cells in very early life stages of the sea anemone Nematostella vectensis suggests that toxins and venom are synthesized already in eggs, embryos and larvae of this species. Here we harness transcriptomic and biochemical tools as well as transgenesis to study venom production dynamics in Nematostella. We find that the venom composition and arsenal of toxin-producing cells change dramatically between developmental stages of this species. These findings might be explained by the vastly different ecology of the larva and adult polyp as sea anemones develop from a miniature non-feeding mobile planula to a much larger sessile polyp that predates on other animals. -

The Associates of Four Species of Marine Sponges of Oregon and Washington Abstract Approved Redacted for Privacy (Ivan Pratt, Major Professor)
AN ABSTRACT OF THE THESIS OF Edward Ray Long for the M. S. in Zoology (Name) (Degree) (Major) /.,, Date thesis presented ://,/,(//i $» I Ì Ì Title The Associates of Four Species of Marine Sponges of Oregon and Washington Abstract approved Redacted for Privacy (Ivan Pratt, Major Professor) Four species of sponge from the coasts of Oregon and Wash- ington were studied and dissected for inhabitants and associates. All four species differed in texture, composition, and habitat, and likewise, the populations of associates of each species differed, even when samples of two of these species were found adjacent to one another. Generally, the relationships of the associates to the host sponges were of four sorts: 1. Inquilinism or lodging, either accidental or intentional; 2. Predation or grazing; 3. Competition for space resulting in "cohabitation" of an area, i, e. a plant or animal growing up through a sponge; and 4. Mutualism. Fish eggs in the hollow chambers of Homaxinella sp. represented a case of fish -in- sponge inqilinism, which is the first such one reported in the Pacific Ocean and in this sponge. The sponge Halichondria panicea, with an intracellular algal symbiont, was found to emit an attractant into the water, which Archidoris montereyensis followed in behavior experiments in preference to other sponges simultane- ously offered. A total of 6098 organisms, representing 68 species, were found associated with the specimens of Halichondria panic ea with densities of up to 19 organisms per cubic centimeter of sponge tissue. There were 9581 plants and animals found with Microciona prolifera, and 150 with Suberites lata.
