COMMISSIONED REPORT Summary Seagrass (Zostera) beds in Orkney Commissioned Report No. 765 Project No: 848 Contractors: Emma Jackson (The Marine Biological Association of the United Kingdom) and Malcolm Thomson (Sula Diving) Year of publication: 2014 Keywords Seagrass; Zostera marina; Orkney; predictive model; survey. Background Seagrasses (Zostera spp) are marine flowering plants that develop on sands and muds in sheltered intertidal and shallow subtidal areas. Seagrass beds are important marine habitats but are vulnerable to a range of human induced pressures. Their vulnerability and importance to habitat creation and ecological functioning is recognised in their inclusion on the recommended Priority Marine Features list for Scotland’s seas. Prior to this study, there were few confirmed records of Zostera in Orkney waters. This study combined a predictive modelling approach with boat-based surveys to enhance under- standing of seagrass distribution in Orkney and inform conservation management. -
IV. Northern South America EIA/ARI World Shale Gas and Shale Oil Resource Assessment
IV. Northern South America EIA/ARI World Shale Gas and Shale Oil Resource Assessment IV. NORTHERN SOUTH AMERICA SUMMARY Northern South America has prospective shale gas and shale oil potential within marine- deposited Cretaceous shale formations in three main basins: the Middle Magdalena Valley and Llanos basins of Colombia, and the Maracaibo/Catatumbo basins of Venezuela and Colombia, Figure IV-1. The organic-rich Cretaceous shales (La Luna, Capacho, and Gacheta) sourced much of the conventional gas and oil produced in Colombia and western Venezuela, and are similar in age to the Eagle Ford and Niobrara shale plays in the USA. Ecopetrol, ConocoPhillips, ExxonMobil, Shell, and others have initiated shale exploration in Colombia. Colombia’s petroleum fiscal regime is considered attractive to foreign investment. Figure IV-1: Prospective Shale Basins of Northern South America Source: ARI 2013 May 17, 2013 IV-1 IV. Northern South America EIA/ARI World Shale Gas and Shale Oil Resource Assessment For the current EIA/ARI assessment, the Maracaibo-Catatumbo Basin was re-evaluated while new shale resource assessments were undertaken on the Middle Magdalena Valley and Llanos basins. Technically recoverable resources (TRR) of shale gas and shale oil in northern South America are estimated at approximately 222 Tcf and 20.2 billion bbl, Tables IV-1 and IV- 2. Colombia accounts for 6.8 billion barrels and 55 Tcf of risked TRR, while western Venezuela has 13.4 billion barrels and 167 Tcf. Eastern Venezuela may have additional potential but was not assessed due to lack of data. Colombia’s first publicly disclosed shale well logged 230 ft of over-pressured La Luna shale with average 14% porosity. -

Onset of the Middle Eocene Global Cooling and Expansion of Open-Vegetation Habitats in Central Patagonia
Andean Geology 41 (1): 29-48. January, 2014 Andean Geology doi: 10.5027/andgeoV41n1-a02 formerly Revista Geológica de Chile www.andeangeology.cl Onset of the Middle Eocene global cooling and expansion of open-vegetation habitats in central Patagonia Eduardo S. Bellosi1, J. Marcelo Krause2 1 Museo Argentino de Ciencias Naturales, Ángel Gallardo 470, 1405 Buenos Aires, Argentina. [email protected] 2 Museo Paleontológico Egidio Feruglio, Fontana 140, 9100 Trelew, Argentina. [email protected] ABSTRACT. Climate-driven changes in terrestrial environments and biomes after the Early Eocene Climatic Optimum are poorly documented from southern continents. Particularly, Middle Eocene-Early Oligocene leaf and pollen data from Central Patagonia (46oS, Argentina) are not sufficient to characterize floristic paleocommunities. Paleosols of the Cañadón Vaca (~45-42 Ma) and Gran Barranca (42-38.5 Ma) members (Sarmiento Formation), studied at Cañadón Vaca, solve such deficiency and help to reconstruct Middle Eocene landscapes in the beginning of the Cenozoic cooling-drying trend. Vitric Entisols, mollic Andisols and andic Alfisols, showing granular structure and diverse micropeds, are cyclically arranged mainly in response to variation in fine volcaniclastic eolian supply, which in turn governed ecosystem stability and maturity. Soils formed in loessic plains crossed by minor ephemeral rivers, supported open herbaceous-arboreal communities which grew in seasonal, subhumid and warm-temperate conditions. Phytoliths produced by Arecaceae, megathermic graminoids, sedges and dicots, from the upper part of the studied unit, represent subtropical savannas with grasses and variable number of palms and other trees. Considering the abundant paleobotanical and paleopedological antecedents of Late Paleocene-Early Eocene warm and humid forested environments in the same region, the lower Sarmiento Formation records the initial expansion of open herbaceous communities and the appearance of grassy habitats during the greenhouse to icehouse transition in the Middle Eocene. -
This Is a Post-Peer-Review, Pre-Copyedit Version of a Chapter Published in “Species Diversity of Animals in Japan” (Motokawa M, Kajihara H, Editors)
This is a post-peer-review, pre-copyedit version of a chapter published in “Species Diversity of Animals in Japan” (Motokawa M, Kajihara H, editors). The final authenticated version is available online at: https://doi.org/10.1007/978-4-431-56432-4_23. Chapter 23 Review of the Taxonomy, Diversity, Ecology, and Other Biological Aspects of Order Tanaidacea from Japan and Surrounding Waters Keiichi Kakui Faculty of Science, Hokkaido University, Sapporo, Hokkaido 060-0810, Japan e-mail: [email protected] telephone: +81-11-706-2750 Abstract The order Tanaidacea is a group of benthic crustaceans, most of which are small, up to a few millimeters long. Tanaidaceans are distributed worldwide, with more than 1,200 described species. Following the first taxonomic paper on a Japanese tanaidacean in 1936, many researchers have studied their taxonomy, morphology, reproductive biology, or ecology in the waters around Japan. This chapter presents a brief introduction to tanaidaceans and then reviews what is known of their systematics (taxonomy and phylogeny), biology (including feeding habits, phenology, morphology, reproductive modes, parasites, predators), and ecology in Japan. The chapter ends with a summary and prospects for future research. The general conclusion is that tanaidaceans have been under-studied, both globally and within Japan; the 104 nominal species reported from around Japan and the 1,200 species reported globally likely represent a fraction of the actual diversity. The phylogeny of tanaidaceans is largely unresolved at all taxonomic levels. Recent, significant new discoveries dealing with herbivory, selfing, skin-digging activity in holothuroid hosts, possible sound production, and tube building suggest that much remains to be learned about their general biology. -
