Smith and De Leo Barkley Canyon Bone
Biodiversity, connectivity and ecosystem function in organic-rich whale-bone and wood- fall habitats in Barkley Canyon PIs Craig R. Smith1 and Fabio De Leo2 1University of Hawaii at Manoa, 2ONC Background: Organic-rich habitat islands support specialized communities throughout natural ecosystems and often play fundamental roles in maintaining alpha and beta diversity, thus facilitating adaptive radiation and evolutionary novelty. In the deep sea, whale-bone and wood falls occur widely and may contribute fundamentally to biodiversity and evolutionary novelty; nonetheless, large-scale patterns of biodiversity, connectivity and ecosystem function in these organic-rich metacommunies remain essentially unexplored. We propose to deploy whale bones and wood in Barkley Canyon at ONC POD3 as part of a novel comparative experimental approach, in which bone and wood substrates are being used to evaluate bathymetric, regional and inter-basin variations in biodiversity and connectivity, as well as interactions between biodiversity and ecosystem function, in whale-bone and wood- fall habitats at the deep-sea floor. The experiments in Barkley Canyon will test fundamental hypotheses concerning biodiversity and biogeography of resource-rich habitats in energy- and oxygen-limited deep-sea environments, and explore the utility of whale-bone and wood falls as model experimental systems to address patterns of connectivity and decomposer function in the deep sea. General Study Design: Two packages of humpback (Megaptera novaeangliae) ribs, and two blocks of Douglas Fir (Pseudotsuga menziesii), will be deployed by ROV on the seafloor at 890- m depth in Barkley Canyon, within view of the POD3 Video Camera (Fig. 1). After deployment, video monitoring of the bone/wood packages will occur every three hours for 5 minutes, with a different experimental package monitored during each 3-h interval; thus, each package will be monitored for two 5-minute periods per day. -
The Potent Respiratory System of Osedax Mucofloris (Siboglinidae, Annelida) - a Prerequisite for the Origin of Bone-Eating Osedax?
The Potent Respiratory System of Osedax mucofloris (Siboglinidae, Annelida) - A Prerequisite for the Origin of Bone-Eating Osedax? Randi S. Huusgaard1, Bent Vismann1, Michael Ku¨ hl1,2, Martin Macnaugton1, Veronica Colmander1, Greg W. Rouse3, Adrian G. Glover4, Thomas Dahlgren5, Katrine Worsaae1* 1 Marine Biological Section, Department of Biology, University of Copenhagen, Helsingør, Denmark, 2 Plant Functional Biology and Climate Change Cluster, Department of Environmental Science, University of Technology Sydney, Sydney, Australia, 3 Scripps Institution of Oceanography, University of California San Diego, San Diego, California, United States of America, 4 Zoology Department, The Natural History Museum, London, United Kingdom, 5 Uni Environment/Uni Research, Bergen, Norway Abstract Members of the conspicuous bone-eating genus, Osedax, are widely distributed on whale falls in the Pacific and Atlantic Oceans. These gutless annelids contain endosymbiotic heterotrophic bacteria in a branching root system embedded in the bones of vertebrates, whereas a trunk and anterior palps extend into the surrounding water. The unique life style within a bone environment is challenged by the high bacterial activity on, and within, the bone matrix possibly causing O2 depletion, and build-up of potentially toxic sulphide. We measured the O2 distribution around embedded Osedax and showed that the bone microenvironment is anoxic. Morphological studies showed that ventilation mechanisms in Osedax are restricted to the anterior palps, which are optimized for high O2 uptake by possessing a large surface area, large surface to volume ratio, and short diffusion distances. The blood vascular system comprises large vessels in the trunk, which facilitate an ample supply of oxygenated blood from the anterior crown to a highly vascularised root structure. -

The IUCN Red List of Threatened Speciestm
Species 2014 Annual ReportSpecies the Species of 2014 Survival Commission and the Global Species Programme Species ISSUE 56 2014 Annual Report of the Species Survival Commission and the Global Species Programme • 2014 Spotlight on High-level Interventions IUCN SSC • IUCN Red List at 50 • Specialist Group Reports Ethiopian Wolf (Canis simensis), Endangered. © Martin Harvey Muhammad Yazid Muhammad © Amazing Species: Bleeding Toad The Bleeding Toad, Leptophryne cruentata, is listed as Critically Endangered on The IUCN Red List of Threatened SpeciesTM. It is endemic to West Java, Indonesia, specifically around Mount Gede, Mount Pangaro and south of Sukabumi. The Bleeding Toad’s scientific name, cruentata, is from the Latin word meaning “bleeding” because of the frog’s overall reddish-purple appearance and blood-red and yellow marbling on its back. Geographical range The population declined drastically after the eruption of Mount Galunggung in 1987. It is Knowledge believed that other declining factors may be habitat alteration, loss, and fragmentation. Experts Although the lethal chytrid fungus, responsible for devastating declines (and possible Get Involved extinctions) in amphibian populations globally, has not been recorded in this area, the sudden decline in a creekside population is reminiscent of declines in similar amphibian species due to the presence of this pathogen. Only one individual Bleeding Toad was sighted from 1990 to 2003. Part of the range of Bleeding Toad is located in Gunung Gede Pangrango National Park. Future conservation actions should include population surveys and possible captive breeding plans. The production of the IUCN Red List of Threatened Species™ is made possible through the IUCN Red List Partnership. -

Deep-sea tubeworms (Annelida, Siboglinidae) represent dominant species in deep-sea chemosynthetic communities (e.g. hydrothermal vents and cold methane seeps) and occur in muddy sediments and organic falls. Siboglinids lack a functional digestive tract as adults, and they rely on endosymbiotic bacteria for energy, making them of evolutionary and physi- ological interest. Despite their importance, inferred evolutionary history of this group has been inconsistent among studies based on different molecular markers. In particular, place- ment of bone-eating Osedax worms has been unclear in part because of their distinctive biol- ogy, including harbouring heterotrophic bacteria as endosymbionts, displaying extreme sexual dimorphism and exhibiting a distinct body plan. Here, we reconstructed siboglinid evolutionary history using 12 newly sequenced transcriptomes. We parsed data into three data sets that accommodated varying levels of missing data, and we evaluate effects of miss- ing data on phylogenomic inference. Additionally, several multispecies-coalescent approaches and Bayesian concordance analysis (BCA) were employed to allow for a compar- ison of results to a supermatrix approach. Every analysis conducted herein strongly sup- ported Osedax being most closely related to the Vestimentifera and Sclerolinum clade, rather than Frenulata, as previously reported. -

Throughout most of its geographical distribution however, it is considered threatened and only two populations are known from Canada. The biology and ecology of S. hermaphrodita are still poorly understood and although few studies have been performed to determine the factors that contribute to the species rarity, it is considered threatened potentially due to the loss of habitat caused by exotic European Common reed (Phragmites australis subsp. -

World Atlas of Biodiversity
WORLD ATLAS OF BIODIVERSITY EARTH'S LIVING RESOURCES IN THE 21st CENTURY ^ > (\ X >r BRIAN GROOMBRIDGE and MARTIN D. JENKINS UNEP WCMC World Atlas of Biodiversity addresses the remark- ible growth in concern at all levels for living things and the environment and the increased appreciation ' the links between the state of ecosystems and the state of humankind. Building on a wealth of re- search and analysis by the conservation community worldwide, this book provides a comprehensive and accessible view of key global issues in biodiver- sity. It outlines some of the broad ecological relationships between humans and the rest of the iterial world and summarizes information on the health of the planet. Opening with an outline of some fundamental aspects of material cycles and energy flow in the biosphere, the book goes on to discuss the expansion of this diversity through geo- logical time and the pattern of its distribution over the surface of the Earth, and analyzes trends in the condition of the main ecosystem types and the species integral to them.
