John Dory (Zeus faber) is a solitary, predatory fish that produces sound when cap- tured, but has not been documented to vocalize under natural conditions (i.e. in the wild). The present study provides the first in-situ recordings of John Dory vocalisations and corre- lates them to behavioural response of snapper (Pagrus auratus) a common species found OPEN ACCESS through New Zealand. Vocalisations or `barks', ranged between 200±600 Hz, with a peak frequency of 312 10 Hz and averaged 139 4 milliseconds in length.

Demersal and Epibenthic Assemblages of Trawlable Grounds in the Northern Alboran Sea (Western Mediterranean)
SCIENTIA MARINA 71(3) September 2007, 513-524, Barcelona (Spain) ISSN: 0214-8358 Demersal and epibenthic assemblages of trawlable grounds in the northern Alboran Sea (western Mediterranean) ESTHER ABAD 1, IZASKUN PRECIADO 1, ALBERTO SERRANO 1 and JORGE BARO 2 1 Centro Oceanográfico de Santander, Instituto Español de Oceanografía, Promontorio de San Martín, s/n, P.O.

Box 285, 29640 Fuengirola, Málaga, Spain SUMMARY: The composition and abundance of megabenthic fauna caught by the commercial trawl fleet in the Alboran Sea were studied. A total of 28 hauls were carried out at depths ranging from 50 to 640 m. As a result of a hierarchical clas- sification analysis four assemblages were detected: (1) the outer shelf group (50-150 m), characterised by Octopus vulgaris and Cepola macrophthalma; (2) the upper slope group (151-350 m), characterised by Micromesistius poutassou, with Plesionika heterocarpus and Parapenaeus longirostris as secondary species; (3) the middle slope group (351-640 m), char- acterised by M. poutassou, Nephrops norvegicus and Caelorhincus caelorhincus, and (4) the small seamount Seco de los Olivos (310-360 m), characterised by M. poutassou, Helicolenus dactylopterus and Gadiculus argenteus, together with Chlorophthalmus agassizi, Stichopus regalis and Palinurus mauritanicus. The results also revealed significantly higher abundances in the Seco de los Olivos seamount, probably related to a higher food availability caused by strong localised cur- rents and upwellings that enhanced primary production. Although depth proved to be the main structuring factor, others such as sediment type and food availability also appeared to be important. -
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.

First record of the reticulated dragonet, Callionymus reticulatus Valenciennes, 1837 (Actinopterygii: Callionymiformes: Callionymidae), from the Balearic Islands, western Mediterranean. Acta Ichthyol. Piscat. 47 (2): 163–171. Background. The reticulated dragonet, Callionymus reticulatus, was originally described based on a single specimen, the holotype from Malaga, Spain, south-western Mediterranean, probably collected before 1831. The holotype is now disintegrated; the specific characteristics are no longer discernible. The species was subsequently recorded from several north-eastern Atlantic localities (Western Sahara to central Norway), but missing in the Mediterranean. Material and methods. Specimens of C. reticulatus were observed and collected during two cruises in 2014 and 2016 in the Balearic Islands off Mallorca and Menorca. The collected specimens (8 females) have been deposited in the collection of the Hebrew University of Jerusalem (HUJ). All individuals of C. reticulatus were collected from beam trawl samples carried out during the DRAGONSAL0914 in September 2014, and during the MEDITS_ES05_16 bottom trawl survey in June 2016, on shelf and slope bottoms around the Balearic Islands. Both surveys used a ‘Jennings’ beam trawl to sample the epi-benthic communities, which was the main objective of the DRAGONSAL0914 and a complementary objective in the MEDITS_ES05_16. The ‘Jennings’ beam trawl has a 2 m horizontal opening, 0.5 m vertical opening and a 5 mm diamond mesh in the codend. -

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -
Appendix 13.2 Marine Ecology and Biodiversity Baseline Conditions
THE LONDON RESORT PRELIMINARY ENVIRONMENTAL INFORMATION REPORT Appendix 13.2 Marine Ecology and Biodiversity Baseline Conditions WATER QUALITY 13.2.1. The principal water quality data sources that have been used to inform this study are: • Environment Agency (EA) WFD classification status and reporting (e.g. EA 2015); and • EA long-term water quality monitoring data for the tidal Thames. Environment Agency WFD Classification Status 13.2.2. The tidal River Thames is divided into three transitional water bodies as part of the Thames River Basin Management Plan (EA 2015) (Thames Upper [ID GB530603911403], Thames Middle [ID GB53060391140] and Thames Lower [ID GB530603911401]. Each of these waterbodies are classified as heavily modified waterbodies (HMWBs). The most recent EA assessment carried out in 2016, confirms that all three of these water bodies are classified as being at Moderate ecological potential (EA 2018). 13.2.3. The Thames Estuary at the London Resort Project Site is located within the Thames Middle Transitional water body, which is a heavily modified water body on account of the following designated uses (Cycle 2 2015-2021): • Coastal protection; • Flood protection; and • Navigation. 13.2.4. The downstream extent of the Thames Middle transitional water body is located approximately 12 km downstream of the Kent Project Site and 8 km downstream of the Essex Project Site near Lower Hope Point. Downstream of this location is the Thames Lower water body which extends to the outer Thames Estuary. 13.2.5. A summary of the current Thames Middle water body WFD status is presented in Table A13.2.1, together with those supporting elements that do not currently meet at least Good status and their associated objectives. -

Ivermectin Binding Sites in Human and Invertebrate Cys-Loop Receptors
1 Ivermectin binding sites in human and invertebrate Cys-loop receptors 2 Timothy Lynagh1, Joseph W. Lynch2 3 4 1 Neurosensory Systems Group, Technical University of Darmstadt, Schnittspahnstrasse 3, 64287 5 Darmstadt, Germany 6 2 Queensland Brain Institute and School of Biomedical Sciences, The University of Queensland, 7 Brisbane, QLD 4072, Australia 8 9 Corresponding author: Lynch, J.W. ([email protected]). Phone: +617 33466375 10 11 1 12 Abstract 13 Ivermectin is a gold-standard antiparasitic drug that has been used successfully to treat billions of 14 humans, livestock and pets. Until recently, the binding site on its Cys-loop receptor target had 15 been a mystery. Recent protein crystal structures, site-directed mutagenesis data and molecular 16 modelling now explain how ivermectin binds to these receptors and reveal why it is selective for 17 invertebrate members of the Cys-loop receptor family. Combining this with emerging genomic 18 information, we are now in a position to predict species sensitivity to ivermectin and better 19 understand the molecular basis of ivermectin resistance. An understanding of the molecular 20 structure of the ivermectin binding site, which is formed at the interface of two adjacent subunits 21 in the transmembrane domain of the receptor, should also aid the development of new lead 22 compounds as both anthelmintics and as therapies for a wide variety of human neurological 23 disorders. 24 25 New insight into a wonder drug 26 Orally- or topically-administered ivermectin is used to eliminate parasitic nematodes and 27 arthropods from animals and humans[1]. It is effective yet well-tolerated due to the potency with 28 which it activates a uniquely invertebrate member of the Cys-loop receptor family of ligand-gated 29 ion channels[2].
