Management Plan For
Measure 8 (2013) Annex Management Plan for Antarctic Specially Protected Area (ASPA) No.138 Linnaeus Terrace, Asgard Range, Victoria Land Introduction Linnaeus Terrace is an elevated bench of weathered Beacon Sandstone located at the western end of the Asgard Range, 1.5km north of Oliver Peak, at 161° 05.0' E 77° 35.8' S,. The terrace is ~ 1.5 km in length by ~1 km in width at an elevation of about 1600m. Linnaeus Terrace is one of the richest known localities for the cryptoendolithic communities that colonize the Beacon Sandstone. The sandstones also exhibit rare physical and biological weathering structures, as well as trace fossils. The excellent examples of cryptoendolithic communities are of outstanding scientific value, and are the subject of some of the most detailed Antarctic cryptoendolithic descriptions. The site is vulnerable to disturbance by trampling and sampling, and is sensitive to the importation of non-native plant, animal or microbial species and requires long-term special protection. Linnaeus Terrace was originally designated as Site of Special Scientific Interest (SSSI) No. 19 through Recommendation XIII-8 (1985) after a proposal by the United States of America. The SSSI expiry date was extended by Resolution 7 (1995), and the Management Plan was adopted in Annex V format through Measure 1 (1996). The site was renamed and renumbered as ASPA No 138 by Decision 1 (2002). The Management Plan was updated through Measure 10 (2008) to include additional provisions to reduce the risk of non-native species introductions into the Area. The Area is situated in Environment S – McMurdo – South Victoria Land Geologic based on the Environmental Domains Analysis for Antarctica and in Region 9 – South Victoria Land based on the Antarctic Conservation Biogeographic Regions. -

Genge Abstract Knowledge of ancient terrestrial hydrothermal systems—how they preserve biological information and how this information can be detected—is important in unraveling the history of life on Earth and, perhaps, that of extinct life on Mars. The Rhynie Chert in Scotland was originally deposited as siliceous sinter from Early Devonian hot springs and contains exceptionally well-preserved fossils of some of the earliest plants and animals to colonize the land. -

Manganese and iron oxides also alteration assemblages and hydrothermal eruption breccias. precipitate from hot-springs, frequently adsorbing high levels of Examples of each of these are found in north-east Scotland, dissolved metals (e.g. Hewett & Fleischer, 1960; Seward & frequently on or near the intersection of major faults and lineaments. Sheppard, 1986). Hydrothermal manganese oxide deposits can be They are all probably the product of Early Devonian geothermal distinguished with confidence on a geochemical basis using a scatter activity which appears to have been widespread in north-east plot (Fig. 2) which is based on the diagnostic hydrothermal Scotland at this time. Six potential gold prospects are identified in enrichments in As, Cu, Mo, Pb, V and Zn (Nicholson, 1986; the region. Nicholson, 1988). Example: A stratiform manganese deposit of limited extent occurs INTRODUCTION at Dalroy (Fig. 1). It overlies Precambrian schists and is itself overlain by conglomerates which mark the onset of Middle Old Red Deposits from active epithermal (geothermal) systems are often Sandstone (ORS« Devonian) sedimentation.

Enigma of Hexapod Evolution
International Journal of Entomology Research International Journal of Entomology Research ISSN: 2455-4758; Impact Factor: RJIF 5.24 Received: 03-11-2019; Accepted: 05-12-2019 www.entomologyjournals.com Volume 5; Issue 1; January 2020; Page No. 13-14 Enigma of hexapod evolution Deepak Rawal Assistant Professor, Department of Zoology, MLSU Udaipur, Rajasthan, India Abstract Modern hexapod diversity represents summation of over 400 million years of high speciation rates and low levels of natural extinction. It seems that nature loves six legs. Out of the million documented species of hexapods, approx 83% are holometabola and largest group (38%) is of Coleoptera (beetles). The gap in the hexapod fossil record is called Hexapod gap. Their origin and evolution is highly debated because there are not enough fossils that directly connect them to the arthropods. Only few fossils found are not enough to precisely solve the mystery of hexapod evolution. There is no doubt that ability of flight gives them power to explore new niches and enhance their biodiversity. Origin and evolution of hexapods is somewhat more complex than it seems. Phylogenetics is not much useful because it requires a previous database to compare things and we does not have database of extinct hexapods. If we want to solve the enigma of hexapod evolution we must find another way which correlate hexapod adaptations with their contemporary environments. Keywords: hexapods, arthropods, brachiopods, myriapods, crustacean, devonian Introduction hypothesis is that hexapods were abundant but don’t seen in Hexapods are the arthropods having six legs and are the fossil record due to bad rocks that does not preserve them. -

Dynamics and Mass Balance of Taylor Glacier, Antarctica: 1
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 114, F04010, doi:10.1029/2009JF001309, 2009 Dynamics and mass balance of Taylor Glacier, Antarctica: 1. Geometry and surface velocities J. L. Kavanaugh,1 K. M. Cuffey,2 D. L. Morse,3 H. Conway,4 and E. Rignot5 Received 15 March 2009; revised 14 June 2009; accepted 7 July 2009; published 3 November 2009. [1] Taylor Glacier, Antarctica, exemplifies a little-studied type of outlet glacier, one that flows slowly through a region of rugged topography and dry climate. This glacier, in addition, connects the East Antarctic Ice Sheet with the McMurdo Dry Valleys, a region much studied for geomorphology, paleoclimate, and ecology. Here we report extensive new measurements of surface velocities, ice thicknesses, and surface elevations, acquired with InSAR, GPS, and GPR. The latter two were used to construct elevation models of the glacier’s surface and bed. Ice velocities in 2002–2004 closely matched those in 2000 and the mid-1970s, indicating negligible interannual variations of flow. Comparing velocities with bed elevations shows that, along much of the glacier, flow concentrates in a narrow axis of relatively fast flowing ice that overlies a bedrock trough. The flow of the glacier over major undulations in its bed can be regarded as a ‘‘cascade’’; it speeds up over bedrock highs and through valley narrows and slows down over deep basins and in wide spots. This pattern is an expected consequence of mass conservation for a glacier near steady state. Neither theory nor data from this Taylor Glacier study support the alternative view, recently proposed, that an outlet glacier of this type trickles slowly over bedrock highs and flows fastest over deep basins.
