Regional Sources of Precipitation in the Ethiopian Highlands Regionala Källor Till Nederbörden I Det Etiopiska Höglandet
Independent Project at the Department of Earth Sciences Självständigt arbete vid Institutionen för geovetenskaper 2015: 2 Regional Sources of Precipitation in the Ethiopian Highlands Regionala källor till nederbörden i det Etiopiska höglandet Elnaz Ashkriz DEPARTMENT OF EARTH SCIENCES INSTITUTIONEN FÖR GEOVETENSKAPER Independent Project at the Department of Earth Sciences Självständigt arbete vid Institutionen för geovetenskaper 2015: 2 Regional Sources of Precipitation in the Ethiopian Highlands Regionala källor till nederbörden i det Etiopiska höglandet Elnaz Ashkriz Copyright © Elnaz Ashkriz and the Department of Earth Sciences, Uppsala University Published at Department of Earth Sciences, Uppsala University (www.geo.uu.se), Uppsala, 2015 Sammanfattning Regionala källor till nederbörden i det Etiopiska höglandet Elnaz Ashkriz Denna uppsats undersöker ursprunget till den stora mängd nederbörd som faller i det etiopiska höglandet. Med Moisture transport into the Ethiopian Highlands av Ellen Viste och Asgeir Sorteberg (2011) som grund syftar denna uppsats till att jämföra samma data men genom att titta på ett mycket kortare intervall för att se vad som försummas när undersökningar på större skalor utförs. Medan undersökningen av Viste och Sorteberg (2011) fokuserar på de två regnrikaste månaderna, juli och augusti under elva år, 1998-2008, så fokuserar denna uppsats enbart på juli år 2008. Syftet med denna uppsats var att se vart nederbörden till det Etiopiska höglandet kommer ifrån under juli månad 2008. För att undersöka detta så har man valt att titta på parametrar såsom horisontell- och vertikal vindriktning på olika höjder samt fukt- innehållet i dessa vindar. Som grund för undersökningen så har denna uppsats, likt Vistes och Sortebergs, använt ERA-Interim data. -
Genetic Adaptation to High Altitude in the Ethiopian Highlands
Scheinfeldt et al. Genome Biology 2012, 13:R1 http://genomebiology.com/2012/13/1/R1 RESEARCH Open Access Genetic adaptation to high altitude in the Ethiopian highlands Laura B Scheinfeldt1, Sameer Soi1, Simon Thompson1, Alessia Ranciaro1, Dawit Woldemeskel2, William Beggs1, Charla Lambert1,3, Joseph P Jarvis1, Dawit Abate2, Gurja Belay2 and Sarah A Tishkoff1,4* Abstract Background: Genomic analysis of high-altitude populations residing in the Andes and Tibet has revealed several candidate loci for involvement in high-altitude adaptation, a subset of which have also been shown to be associated with hemoglobin levels, including EPAS1, EGLN1, and PPARA, which play a role in the HIF-1 pathway. Here, we have extended this work to high- and low-altitude populations living in Ethiopia, for which we have measured hemoglobin levels. We genotyped the Illumina 1M SNP array and employed several genome-wide scans for selection and targeted association with hemoglobin levels to identify genes that play a role in adaptation to high altitude. Results: We have identified a set of candidate genes for positive selection in our high-altitude population sample, demonstrated significantly different hemoglobin levels between high- and low-altitude Ethiopians and have identified a subset of candidate genes for selection, several of which also show suggestive associations with hemoglobin levels. Conclusions: We highlight several candidate genes for involvement in high-altitude adaptation in Ethiopia, including CBARA1, VAV3, ARNT2 and THRB. Although most of these genes have not been identified in previous studies of high-altitude Tibetan or Andean population samples, two of these genes (THRB and ARNT2) play a role in the HIF-1 pathway, a pathway implicated in previous work reported in Tibetan and Andean studies. -

Box 231, Mekelle, Ethiopia Received: 14 March 2014; Revised: 14 August 2014; Accepted: 18 August 2014 ABSTRACT High-altitude forests are very important for local livelihood in the vulnerable environment of the densely populated tropical highlands. Humans need the ecosystem services of the forest and directly impact the forest through livestock herding, fire, and wood harvesting. Nev- ertheless, temperature-sensitive tree lines in the tropics are scarcely investigated in comparison with higher northern latitudes. In this study, the Erica arborea L. tree line is studied in a tropical mountain in the North Ethiopian highlands: Lib Amba of the Abune Yosef Mountain range (12°04′N, 39°22′E, 3993 m asl). The present tree line and forest cover was recorded by high-resolution satellite imagery from Google Maps and field data (2010–2013), while historical forest cover was studied from aerial photographs (1965–1982) and repeat photography (1917–2013). The aerial and satellite images were orthorectified and classified in forest/non-forest binary maps. -

Alaska Range
Alaska Range Introduction The heavily glacierized Alaska Range consists of a number of adjacent and discrete mountain ranges that extend in an arc more than 750 km long (figs. 1, 381). From east to west, named ranges include the Nutzotin, Mentas- ta, Amphitheater, Clearwater, Tokosha, Kichatna, Teocalli, Tordrillo, Terra Cotta, and Revelation Mountains. This arcuate mountain massif spans the area from the White River, just east of the Canadian Border, to Merrill Pass on the western side of Cook Inlet southwest of Anchorage. Many of the indi- Figure 381.—Index map of vidual ranges support glaciers. The total glacier area of the Alaska Range is the Alaska Range showing 2 approximately 13,900 km (Post and Meier, 1980, p. 45). Its several thousand the glacierized areas. Index glaciers range in size from tiny unnamed cirque glaciers with areas of less map modified from Field than 1 km2 to very large valley glaciers with lengths up to 76 km (Denton (1975a).

Sedimentological Constraints on the Initial Uplift of the West Bogda Mountains in Mid-Permian
www.nature.com/scientificreports OPEN Sedimentological constraints on the initial uplift of the West Bogda Mountains in Mid-Permian Received: 14 August 2017 Jian Wang1,2, Ying-chang Cao1,2, Xin-tong Wang1, Ke-yu Liu1,3, Zhu-kun Wang1 & Qi-song Xu1 Accepted: 9 January 2018 The Late Paleozoic is considered to be an important stage in the evolution of the Central Asian Orogenic Published: xx xx xxxx Belt (CAOB). The Bogda Mountains, a northeastern branch of the Tianshan Mountains, record the complete Paleozoic history of the Tianshan orogenic belt. The tectonic and sedimentary evolution of the west Bogda area and the timing of initial uplift of the West Bogda Mountains were investigated based on detailed sedimentological study of outcrops, including lithology, sedimentary structures, rock and isotopic compositions and paleocurrent directions. At the end of the Early Permian, the West Bogda Trough was closed and an island arc was formed. The sedimentary and subsidence center of the Middle Permian inherited that of the Early Permian. The west Bogda area became an inherited catchment area, and developed a widespread shallow, deep and then shallow lacustrine succession during the Mid- Permian. At the end of the Mid-Permian, strong intracontinental collision caused the initial uplift of the West Bogda Mountains. Sedimentological evidence further confrmed that the West Bogda Mountains was a rift basin in the Carboniferous-Early Permian, and subsequently entered the Late Paleozoic large- scale intracontinental orogeny in the region. The Central Asia Orogenic Belt (CAOB) is the largest accretionary orogen on Earth, which was formed by the amalgamation of multiple micro-continents, island arcs and accretionary wedges1–5. -

The whole area is characterised by a through-flow karst system, where subsurface streams submerging at Duvanjsko polje are directed towards springs at Livanjsko polje. In this study, we conducted morphographic and morphometric investigation of surface and sub- surface features, especially collapse dolines, denuded caves along with active and inactive cave systems. We interpreted morphogenesis and past hydrologic pattern within the area.
