Received: 23 October 2019; Accepted: 15 December 2019; Published: 18 December 2019 Abstract: Utricularia belongs to Lentibulariaceae, a widespread family of carnivorous plants that possess ultra-small and highly dynamic nuclear genomes. It has been shown that the Lentibulariaceae genomes have been shaped by transposable elements expansion and loss, and multiple rounds of whole-genome duplications (WGD), making the family a platform for evolutionary and comparative genomics studies. To explore the evolution of Utricularia, we estimated the chromosome number and genome size, as well as sequenced the terrestrial bladderwort Utricularia reniformis (2n = 40, 1C = 317.1-Mpb).

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. Main Species Sponges sponges (numerous species, in genera Dysidea, Euryspongia, Darwinella, Aplysilla, Dendrilla, Clathrina and many others) Ascidians / Sea Squirts Red-mouthed Ascidian, Obese Ascidian, and other solitary ascidians / sea squirts Brain Ascidian, and other colonial ascidians Spongy Compound, Leach’s Compound & other compound ascidians Corals gorgonian corals such as Mopsella zimmeri (on current-exposed jetties) soft corals, such as Carijoa (also Drifa sp. on current-exposed jetties) solitary coral Scolymia Bryozoans various species, including various species in Cellaporaria (such as Orange Plate Bryozoan and Nipple Bryozoan) and species in Triphyllozoon (Lace Bryozoans) Gastropod Shells Cowries, Cartrut shell, Triton shells Bivalve Shells Doughboy Scallop, Razorfish Shell, juvenile Native Oyster Jetties, shipwrecks and other artificial reefs.

  • An Overview of the Elasmobranch By-Catch of the Queensland East Coast Trawl Fishery (Australia) (Elasmobranch Fisheries – Oral)
    NOT TO BE CITED WITHOUT PRIOR REFERENCE TO THE AUTHOR(S) Northwest Atlantic Fisheries Organization Serial No. N4718 NAFO SCR Doc. 02/97 SCIENTIFIC COUNCIL MEETING – SEPTEMBER 2002 An Overview of the Elasmobranch By-catch of the Queensland East Coast Trawl Fishery (Australia) (Elasmobranch Fisheries – Oral) by P. M. Kynea, A.J. Courtneyb, M.J. Campbellb, K.E. Chilcottb, S.W. Gaddesb, C.T. Turnbullc, C.C. Van Der Geestc and M. B. Bennetta a Department of Anatomy and Developmental Biology, The University of Queensland, Brisbane, 4072, Queensland, Australia b Southern Fisheries Centre, Queensland Department of Primary Industries, PO Box 76, Deception Bay, 4508, Queensland, Australia c Northern Fisheries Centre, Queensland Department of Primary Industries, PO Box 5396, Cairns, 4870, Queensland, Australia E-mail: [email protected] Abstract The Queensland East Coast Trawl Fishery (ETCF) is a complex multi-species and multi-sector fishery operating along Queensland’s eastern coastline, with combined annual landings of close to 10 000 tons. 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).

Dipper Occasional Paper of the IUCN Species Survival Commission No. 25 IUCN The World Conservation Union Donors to the SSC Conservation Communications Programme and Elasmobranch Biodiversity, Conservation and Management: Proceedings of the International Seminar and Workshop, Sabah, Malaysia, July 1997 The IUCN/Species Survival Commission is committed to communicate important species conservation information to natural resource managers, decision-makers and others whose actions affect the conservation of biodiversity. 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.

  • The Island Rule and Its Application to Multiple Plant Traits
    The island rule and its application to multiple plant traits Annemieke Lona Hedi Hendriks A thesis submitted to the Victoria University of Wellington in partial fulfilment of the requirements for the degree of Master of Science in Ecology and Biodiversity Victoria University of Wellington, New Zealand 2019 ii “The larger the island of knowledge, the longer the shoreline of wonder” Ralph W. Sockman. iii iv General Abstract Aim The Island Rule refers to a continuum of body size changes where large mainland species evolve to become smaller and small species evolve to become larger on islands. Previous work focuses almost solely on animals, with virtually no previous tests of its predictions on plants. I tested for (1) reduced floral size diversity on islands, a logical corollary of the island rule and (2) evidence of the Island Rule in plant stature, leaf size and petiole length. Location Small islands surrounding New Zealand; Antipodes, Auckland, Bounty, Campbell, Chatham, Kermadec, Lord Howe, Macquarie, Norfolk, Snares, Stewart and the Three Kings. Methods I compared the morphology of 65 island endemics and their closest ‘mainland’ relative. Species pairs were identified. Differences between archipelagos located at various latitudes were also assessed. Results Floral sizes were reduced on islands relative to the ‘mainland’, consistent with predictions of the Island Rule. Plant stature, leaf size and petiole length conformed to the Island Rule, with smaller plants increasing in size, and larger plants decreasing in size. Main conclusions Results indicate that the conceptual umbrella of the Island Rule can be expanded to plants, accelerating understanding of how plant traits evolve on isolated islands.
