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. -

Group Organisers Manual
Group Organisers Manual Welcome to McCabe Pilgrimages Alistair McCabe’s involvement in pilgrimage dates back to 1976 when, straight out of university, he was appointed assistant warden of the then Scots Hospice beside the Sea of Galilee: an opportune introduction to pilgrimage and pilgrim parties. This led to managing the Holy Land department of Inter Church Travel working alongside the great pilgrimage innovator, Canon Arthur Payton. When Arthur retired in 1983, the time was right for McCabe Pilgrimages to be born. Rosemary Nutt joined the company shortly afterwards and Alistair and Rosemary are still the heart and soul of the company. We have an excellent team, and our empathy with the needs of pilgrimage organisers is unrivalled. Make an enquiry Let us send you a no obligation suggestion for a pilgrimage from your church. Email or call us and we will send you ideas. Our website has lots of itineraries for you to browse. www.mccabe-travel.co.uk | 020 8675 6828 [email protected] 2 www.mccabe-travel.co.uk 020 8675 6828 Sponsored Walk by the Sea of Galilee 3 A word about health and fitness McCabe website Preparing to Many pilgrims are elderly. Age itself is not You decide whether you would like us to a barrier, but a certain level of fitness is promote your tour through the McCabe required. Think in terms of being able to website. This can be a way of building up lead a pilgrimage walk unaided for at least thirty minutes on numbers, but you may prefer to only recruit uneven ground. -
