University, Perth, WA 6027, Australia Location Four hundred kilometres of exposed surf beaches along the eastern coastline of Australia. A Journal of Conservation Biogeography Methods Fish assemblages were surveyed from surf zones of 14 ocean-exposed sandy beaches using purpose-built surf baited remote underwater video sta- tions. Results The degree of coastal urbanization and connectivity were strongly cor- related with the spatial distribution of fish species richness and abundance and were of greater importance to surf fishes than local surf conditions. Urbaniza- tion was associated with reductions in the abundance of harvested piscivores and fish species richness. Piscivore abundance and species richness were lowest on highly urbanized coastlines, and adjacent to beaches in wilderness areas where recreational fishing is intense. -

The list is the result of regular queries in numerous journals, books and online publications. It provides a complete list of publication citations as well as a database report containing rearranged subsets of the list sorted by the keyword statistics, extant and extinct genera and species descriptions from the years 2000 to 2016, list of descriptions of extinct and extant species from 2016, parasitology, reproduction, distribution, diet, conservation, and taxonomy. The paper is intended to be consulted for information. In addition, we provide information on the geographic and depth distribution of newly described species, i.e. the type specimens from the year 1990- 2016 in a hot spot analysis.

SCHMIDT Deparbnent of Biology, University of Northern Colorado, Greeley, Colorado 80631 ABSTRACT: Acanthobothrium urolophi sp. n. is described from a common stingaree, Urolophus testa cet/s, from South Australia. It differs from all other species in being apolytic and acraspedote, in having hooks 105-115 fJ- long, one accessory sucker 80-90 wide on each bothridinm, and 40-72 testes in two longitudinal rows. This report is based upon four specimens on anterior end of each bothridium, each with recovered from the spiral valve of a common single accessory sucker 80 to 90 wide. -

Report for Natural Resources - Northern and Yorke / NY NRM Board, South Australia. 16. Jetties, Shipwrecks and Other Artificial Reefs Edithburgh Kleins Point © D. Kinasz © J. Zhang Asset Jetties, Shipwrecks and other Artificial Reefs Description Structures of wood, iron, steel, and other materials, throughout the NY NRM region, ranging from oceanographically exposed through to sheltered locations. Jetties and shipwrecks function as surfaces for attachment of marine plants and attached invertebrates; sheltering and feeding areas for fishes, sharks, rays and invertebrates; and as “fish-attracting” devices, periodically visited by schooling fishes which are attracted to vertical structure. Surrounding sea floor varies according to the location of the jetty or wreck, and includes reef, seagrass, sand, and rubble. There are also two purpose-built artificial reefs in the NY NRM region, constructed of tetrahedon module units, made up vehicle tyres.

Elasmobranchs represent a relatively small, but potentially ecologically significant component of by-catch in this fishery. At least 94 species of elasmobranchs occur in the managed area of the ECTF and a study has been initiated to examine elasmobranch by-catch in four sectors of the fishery, as part of a larger Queensland Department of Primary Industries by-catch project. A total of 42 elasmobranch and one holocephalan species have been recorded as by- catch in the fishery. Preliminary results from fishery-independent (FI) surveys indicate that elasmobranch by-catch is highly variable between fishery sectors. Elasmobranch by-catch is extremely low in the tiger/Endeavour prawn sector, low in the eastern king prawn – deep water sector (EKP-D), and moderate in the EKP – shallow water sector (EKP-S). -

The SSC's Action Plans, Occasional Papers, newsletter Species and other publications are supported by a wide variety of generous donors including: The Sultanate of Oman established the Peter Scott IUCN/SSC Action Plan Fund in 1990. The Fund supports Action Plan development and implementation. To date, more than 80 grants have been made from the Fund to SSC Specialist Groups. The SSC is grateful to the Sultanate of Oman for its confidence in and support for species conservation worldwide. The Council of Agriculture (COA), Taiwan has awarded major grants to the SSC's Wildlife Trade Programme and Conservation Communications Programme. This support has enabled SSC to continue its valuable technical advisory service to the Parties to CITES as well as to the larger global conservation community. Among other responsibilities, the COA is in charge of matters concerning the designation and management of nature reserves, conservation of wildlife and their habitats, conservation of natural landscapes, coordination of law enforcement efforts as well as promotion of conservation education, research and international cooperation. -
