Detrital Zircon Geochronology of Palaeozoic Siliciclastic Rocks from the Ellsworth Mountains, West Antarctica

In the Ellsworth Mountains there is an extensive record of sedimentation from early Cambrian to Permian times. However, the tectonic history and the palaeogeographic significance remain enigmatic. Nine sandstone samples were analysed for their U-Pb detrital zircon age spectra using SHRIMPII and RG. They belong to the early Cambrian to Carboniferous-Permian sequences and record typical Gondwana margin signatures. Variations up section/sequence in zircon provenance suggest restricted basinal deposition during the Cambrian,! with likely sources in the Namaqua-Natal and Mozambique/Maud Belts. There are little or no contributions from older cratons and so the Ellsworth basin evolved as a separate basin to that in the Transantarctic Mountains.! This basin configuration changed after the Devonian and deposition continued Figure 1.

Indiana Forest Action Plan 2020 UPDATE
Indiana Forest Action Plan 2020 UPDATE Indiana Forest Action Plan 2020 UPDATE Strategic Goals: • Conserve, manage and protect existing forests, especially large forest patches, with increased emphasis on oak regeneration • Restore, expand and connect forests, especially in riparian areas • Connect people to forests, especially children and land-use decision makers, and coordinate education training and technical assistance • Maintain and expand markets for Indiana hardwoods, with special focus on secondary processors and promoting the environmental benefits of wood products to local communities and school groups • Significantly increase the size of Indiana’s urban forest canopy by developing community assistance programs and tools Indiana Forest Action Plan | 2020 Update 1 Executive Summary The 2020 Indiana Forest Action Plan is an update to the 2010 Indiana Statewide Forest Assessment and Indiana Statewide Forest Strategy. The purpose remains unchanged: to address the sustainability of Indiana’s statewide forests and develop a plan to ensure a desired future condition for forests in the state. This plan is distinct from the Indiana DNR Division of Forestry Strategic Direction 2020-2025. Indiana forest stakeholders participating in developing this Forest Action Plan maintained the broader perspective of all forest lands, public and private, and based recommendations on the roughly 5 million acres of forest in Indiana throughout the document. This document includes conditions and trends of forest resources in the state, threats to forest -
False Black Widows and Other Household Spiders
False Black Widows and Other Household Spiders Spiders can quite unnecessarily evoke all kinds of dread and fear. The Press does not help by publishing inaccurate and often alarmist stories about them. Spiders are in fact one of our very important beneficial creatures. Spiders in the UK devour a weight of insect 'pests' equivalent to that of the nation's human population! During the mid-late summer, many spiders mature and as a result become more obvious as they have then grown to their full size. One of these species is Steatoda nobilis. It came from the Canary and Madeiran Islands into Devon over a 100 years ago, being first recorded in Britain near Torquay in 1879! However it was not described from Britain until 1993, when it was known to have occurred since at least 1986 and 1989 as flourishing populations in Portsmouth (Hampshire) and Swanage (Dorset). There was also a population in Westcliff-on-Sea (Essex) recorded in 1990, and another in Littlehampton and Worthing (West Sussex). Its distribution is spreading more widely along the coast in the south and also inland, with confirmed records from South Devon, East Sussex, Kent, Surrey and Warwick. The large, grape-like individuals are the females and the smaller, more elongate ones, the males. These spiders are have become known as False Widows and, because of their colour, shape and size, are frequently mistaken for the Black Widow Spider that are found in warmer climes, but not in Britain (although some occasionally come into the country in packaged fruit and flowers). Black Widow Spiders belong to the world-wide genus Latrodectus. -
The Behavioural Ecology of Latrodectus Hasselti (Thorell), the Australian Redback Spider (Araneae: Theridiidae): a Review
Records of the Western Australian MIISellnl Supplement No. 52: 13-24 (1995). The behavioural ecology of Latrodectus hasselti (Thorell), the Australian Redback Spider (Araneae: Theridiidae): a review Lyn Forster McMasters Road, RD 1, Saddle Hill, Dunedin, New Zealand Abstract - Aspects of the biogeographical history and behavioural ecology of the AustralIan Latrodectus hasseIti provide support for the endemic status of this species. Cannibalism, prey stealing and short instar lengths are growth strategies for. female spiders whereas early maturation, small size, hiding and scavengmg are useful survival tactics for males. Moreover male complicity is an important component of sexual cannibalism which is ~hown to be a highly predictable event. Latrodectus hasseIti males hybridize with female L. katlpo (a New Zealand species) and fertile Fl and F2 generations Imply genetic relatedness. Hence, it is likely that L. hasselti and L. katipo evolv~d from a common ancestor in ancient Pangaea, a feasible explanation only If L. hasseItl IS endemic to Australia. It is concluded that L. hasseIti would have been able to persist in outback Australia for millions of years, with ItS mtraspeClfJc predatory habits aiding subsistence and the evolution of sexual cannibalism providing a way of coping with infrequent meeting and matmg opportunities. INTRODUCTION indigenous status, Main (1993) notes that, (as a Many stories and articles have been written consequence of its supposed introduction), "the about the redback spider (McKeown 1963; Raven absence of Latrodectus in the Australian region, 1992) with considerable attention being devoted to prior to human habitation, poses a curious its venomous nature (Southcott 1978; Sutherland zoogeographic dilemma". This comment raises an and Trinca 1978). -

ONE 1985 EDITION This yearly report to the members is the method by which the history of the Indianapolis Hiking Club is chronicled and kept up to dat e . The club enjoyed an exciting and interesting schedule of events last year, as it complet ed the 28th year of exis t ence, following the purpose for which it was organized; "To encourage a love of nature, through the promotion of outdoor recreation in the form of hikes and outings, and to sponsor other activities incidental to the foregoing" . Any organization needs the participation of individual members to be s trong and vibrant, and the Indianapolis Hiking Club excels in this r espect. The active and enthusiastic support of a l arge percent of the membership has helped to make t he club the outstanding outdoor recreation group in Indiana. The total paid up membership at the end of the year wa s 368. During the year the c lub sponsored 198 hikes , and 3 overnight outings, ·the summer picnic, the Christmas Party, and a backpack.

Subsurface Facies Analysis of the Devonian Berea Sandstone in Southeastern Ohio
SUBSURFACE FACIES ANALYSIS OF THE DEVONIAN BEREA SANDSTONE IN SOUTHEASTERN OHIO William T. Garnes A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE December 2014 Committee: James Evans, Advisor Jeffrey Snyder Charles Onasch ii ABSTRACT James Evans, Advisor The Devonian Berea Sandstone is an internally complex, heterogeneous unit that appears prominently both in outcrop and subsurface in Ohio. While the unit is clearly deltaic in outcrops in northeastern Ohio, its depositional setting is more problematic in southeastern Ohio where it is only found in the subsurface. The goal of this project was to search for evidence of a barrier island/inlet channel depositional environment for the Berea Sandstone to assess whether the Berea Sandstone was deposited under conditions in southeastern Ohio unique from northeastern Ohio. This project involved looking at cores from 5 wells: 3426 (Athens Co.), 3425 (Meigs Co.), 3253 (Athens Co.), 3252 (Athens Co.), and 3251 (Athens Co.) In cores, the Berea Sandstone ranges from 2 to 10 m (8-32 ft) thick, with an average thickness of 6.3 m (20.7 ft). Core descriptions involved hand specimens, thin section descriptions, and core photography. In addition to these 5 wells, the gamma ray logs from 13 wells were used to interpret the architecture and lithologies of the Berea Sandstone in Athens Co. and Meigs Co. as well as surrounding Vinton, Washington, and Morgan counties. Analysis from this study shows evidence of deltaic lobe progradation, abandonment, and re-working. Evidence of interdistributary bays with shallow sub-tidal environments, as well as large sand bodies, is also present.
