  • Anyone for Slugs? - Densey Clyne
    Anyone for Slugs? - Densey Clyne No, thank you very much, you will be thinking. Slimy pests with no redeeming features at all - away with them! Well yes, some of them, but others deserve a closer look. If I had not become so thoroughly captivated by six-legged and eight-legged arthropods so early in my life I believe it would have been the slugs and snails that took my fancy. There is something so elegant about a snail gliding along, rather like a ship on a calm sea, and the courtship and mating habits of slugs can be spectacular. But one particular kind of slug has always intrigued me. Over the summer months one of the smooth-barked gumtrees in my Wauchope garden acquires an artistic pattern of meandering squiggles. One rainy night I went out after dark and there was the artist, moving very slowly high up on a branch - my old friend first met in Sydney, the Red Triangle slug, Triboniophorus graeffei. It was my first sighting of the slug in my new garden though I had recognised its squiggles on the gumtree. This year I’ve been excited to find them for the first time on my crepe Triboniophorus graeffei on gumtree myrtle trees, planted 5 years ago. I first got to know these slugs years ago in an overgrown Sydney suburban garden where giant bluegums grew on rich soil and it rained a lot. The slugs had taken a liking to a mature crepe myrtle tree, adding an extra touch to its beautifully patterned trunk. As well as being much bigger - up to 140mm - these slugs were different from any other slugs I knew.

Snails were collected monthly during the study period and sampled using a combination of indirect litter sample methods and timed direct search. Snails collected were kept in labeled specimen vials and transported to the National Museums of Kenya for identification using keys and reference collection. In order to understand environmental variables that affect soil snail abundance; canopy, soil pH and temperature was measured per plot while humidity and rainfall data was obtained from the nearest weather stations to the study sites. A total of 2881 snail specimens (29 species from 10 families) were recorded. The families Subulinidae, Charopidae and Urocyclidae were found to be dorminant. The most abundant species was Opeas lamoense (12% of the sample).

    Review of Environmental Factors Core Hole Drilling of Turill No. 1 in PEL 456 - Gunnedah Basin Santos QNT Pty Ltd ABN: 33 083 077 196 Issue date: 04/05/2010 Review of Environmental Factors: Gunnedah Basin Core Hole Drilling: PEL 456 Executive Summary Santos QNT Pty Ltd (Santos) has entered into a Farmin Agreement with the titleholder of PEL 456, Macquarie Energy (Macquarie) to explore for petroleum (in accordance with the Petroleum (Onshore) Act 1991 (NSW)). Santos has been appointed the Operator for and on behalf of the titleholder under the Farmin Agreement. Condition 1.0 of the PEL 456 licence states that prior to carrying out any drilling activities a Review of Environmental Factors (REF) is required to be submitted to the Department of Industry and Investment (DII) to enable a determination to be made under Part 5 of the Environmental Planning and Assessment Act 1979 (NSW). The Turill 1 core hole is designed to investigate the hydrocarbon potential of PEL 456. Discovery of gas resources in this area has the potential to increase the state’s reserves and revenue from coal seam gas and underpin future exploration or production in the region. This REF covers the drilling of Turill 1 core hole only. The Turill No. 1 core hole site is located on privately owned land, zoned General Rural 1(a) under the Merriwa Local Environmental Plan (LEP). The REF provides details of the planning controls for the area and the existing environment. The site proposed for Turill 1 is a privately owned rural property in a gently undulating area, which is presently used for agricultural activities.

  • Terrestrial Mollusks of Attu, Aleutian Islands, Alaska BARRY ROTH’ and DAVID R
    ARCTK: VOL. 34, NO. 1 (MARCH 1981), P. 43-47 Terrestrial Mollusks of Attu, Aleutian Islands, Alaska BARRY ROTH’ and DAVID R. LINDBERG’ ABSTRACT. Seven species of land mollusk (2 slugs, 5 snails) were collected on Attu in July 1979. Three are circumboreal species, two are amphi-arctic (Palearctic and Nearctic but not circumboreal), and two are Nearctic. Barring chance survival of mollusks in local refugia, the fauna was assembled overwater since deglaciation, perhaps within the last 10 OOO years. Mollusk faunas from Kamchatka to southeastern Alaska all have a Holarctic component. A Palearctic component present on Kamchatka and the Commander Islands is absent from the Aleutians, which have a Nearctic component that diminishes westward. This pattern is similar to that of other soil-dwelling invertebrate groups. RESUM& Sept espbces de mollusques terrestres (2 limaces et 5 escargots) furent prklevkes sur I’ile d’Attu en juillet 1979.
