(80 marks) Marking Scheme: Number of aspects discussed: 3 @ 20 marks each 4 @ 15 marks each For each aspect: Identifying aspect 4 marks 3 marks Discussion 8 x SRPs 6 x SRPs Overall Coherence 20 marks graded* 20 marks graded* In this answer, I choose 3 aspects to discuss (1. Climate, 2. Climate’s impact on soil and, 3. Climate’s impact on vegetation). Overall coherence means how well your answer is structured (Introduction, main section, conclusion – well-structured and coherent) and do you keep to the point/ answer the question directly. Introduction: In this answer I am going to discuss the type of climate experienced in the hot desert biome and how this climate impacts on soils and vegetation within this biome. Biomes are classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment. They are a large geographical area controlled by climate. Therefore the climate of a particular region will affect what type of soil is formed in that biome as well as what types of plants (flora) grow there. The hot desert that I have studied is the North American Desert Biome. Body of Topic: A desert biome can be defined as an arid region that is characterised by little or no rainfall, in which vegetation is scarce or absent, unless it has specially adapted. As a result of its location, between 15º and 30º north of the Equator, the climate of the hot desert biome is hot and dry. -

Tree Growth and Water-Use in Hyper-Arid Acacia Occurs During The
Oecologia https://doi.org/10.1007/s00442-018-4250-z PHYSIOLOGICAL ECOLOGY - ORIGINAL RESEARCH Tree growth and water‑use in hyper‑arid Acacia occurs during the hottest and driest season Gidon Winters1 · Dennis Otieno2 · Shabtai Cohen3 · Christina Bogner4 · Gideon Ragowloski1 · Indira Paudel5 · Tamir Klein5 Received: 10 April 2018 / Accepted: 13 August 2018 © Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract Drought-induced tree mortality has been recently increasing and is expected to increase further under warming climate. Conversely, tree species that survive under arid conditions might provide vital information on successful drought resistance strategies. Although Acacia (Vachellia) species dominate many of the globe’s deserts, little is known about their growth dynamics and water-use in situ. Stem diameter dynamics, leaf phenology, and sap fow were monitored during 3 consecutive years in fve Acacia raddiana trees and fve Acacia tortilis trees in the Arid Arava Valley, southern Israel (annual precipitation 20–70 mm, restricted to October–May). We hypothesized that stem growth and other tree activities are synchronized with, and limited to single rainfall or fashfood events. Unexpectedly, cambial growth of both Acacia species was arrested during the wet season, and occurred during most of the dry season, coinciding with maximum daily temperatures as high as 45 °C and vapor pressure defcit of up to 9 kPa. Summer growth was correlated with peak sap fow in June, with almost year-round activity and foliage cover. To the best of our knowledge, these are the harshest drought conditions ever documented permitting cambial growth. These fndings point to the possibility that summer cambial growth in Acacia under hyper-arid conditions relies on concurrent leaf gas exchange, which is in turn permitted by access to deep soil water. -
Himalaya - Southern-Tibet: the Typical Continent-Continent Collision Orogen
237 Himalaya - Southern-Tibet: the typical continent-continent collision orogen When an oceanic plate is subducted beneath a continental lithosphere, an Andean mountain range develops on the edge of the continent. If the subducting plate also contains some continental lithosphere, plate convergence eventually brings both continents into juxtaposition. While the oceanic lithosphere is relatively dense and sinks into the asthenosphere, the greater sialic content of the continental lithosphere ascribes positive buoyancy in the asthenosphere, which hinders the continental lithosphere to be subducted any great distance. Consequently, a continental lithosphere arriving at a trench will confront the overriding continent. Rapid relative convergence is halted and crustal shortening forms a collision mountain range. The plane marking the locus of collision is a suture, which usually preserves slivers of the oceanic lithosphere that formerly separated the continents, known as ophiolites. The collision between the Indian subcontinent and what is now Tibet began in the Eocene. It involved and still involves north-south convergence throughout southern Tibet and the Himalayas. This youthful mountain area is the type example for studies of continental collision processes. The Himalayas Location The Himalayas form a nearly 3000 km long, 250-350 km wide range between India to the south and the huge Tibetan plateau, with a mean elevation of 5000 m, to the north. The Himalayan mountain belt has a relatively simple, arcuate, and cylindrical geometry over most of its length and terminates at both ends in nearly transverse syntaxes, i.e. areas where orogenic structures turn sharply about a vertical axis. Both syntaxes are named after the main peaks that tower above them, the Namche Barwa (7756 m) to the east and the Nanga Parbat (8138 m) to the west, in Pakistan. -

Secondly, based on the ERA-Interim Reanalysis from ECMWF and MISR data from the Terra satellite, we investigate the correlation between different dust weather process and land meteorological elements. Finally, the temporal and spatial distribution features of the aerosol optical depth (AOD) in the Taklamakan Desert is studied. And we compare the Taklamakan Desert AOD with nationwide AOD. The results show that: (1) the frequency of sandstorm and strong sandstorm has shown a downward trend and the occurrence of sandstorm decreases more in recent years. (2) In the Taklamakan Desert, the number of sandstorm is positively correlated with the surface temperature, meanwhile, negatively related to the surface relative humidity. (3) In all seasons, the average of AOD in Taklamakan Desert is higher than that of the whole country, and there are obvious differences among the four seasons. 1 Introduction climate model to predict the abnormal climate and sandstorm 8. Sandstorm is a weather phenomenon that strong wind Since the occurrence of sandstorm is directly affected blows dust on the ground, making the air turbid and by the surface meteorological elements, it is essential to causing the level of visibility less than 1km 1. -

Received: 14 December 2018; Accepted: 24 January 2019; Published: 29 January 2019 Abstract: The uplift of the Qinghai-Tibetan Plateau (QTP) had a profound impact on the plant speciation rate and genetic diversity. High genetic diversity ensures that species can survive and adapt in the face of geographical and environmental changes. The Tanggula Mountains, located in the central of the QTP, have unique geographical significance. The aim of this study was to investigate the effect of the Tanggula Mountains as a geographical barrier on plant genetic diversity and structure by using Lancea tibetica. A total of 456 individuals from 31 populations were analyzed using eight pairs of microsatellite makers. The total number of alleles was 55 and the number per locus ranged from 3 to 11 with an average of 6.875. The polymorphism information content (PIC) values ranged from 0.2693 to 0.7761 with an average of 0.4378 indicating that the eight microsatellite makers were efficient for distinguishing genotypes. -

Then, based on the SPEI data, drought on the Qinghai-Tibet Plateau was studied in terms of its spatial and temporal distributions and its changing characteristics over the last 100 years. 10 The results revealed that the precipitation in the southeastern part of the Qinghai-Tibet Plateau has been steadily rising over the last 100 years, in conjunction with only minor temperature shifts. In the northwestern part of the plateau, precipitation has decreased significantly, accompanied by a significant increase in temperature. The drought on the Qinghai-Tibetan Plateau showed a clear gradual increase in aridity from southeast to northwest over the last hundred years. The SPEI also showed distinct seasonal patterns, steadily increasing in spring and summer and decreasing significantly in autumn and winter. In 15 addition, each season had its own spatial characteristics. The northeastern part of the plateau, except the Qaidam Basin, showed a significant aridity trend in all seasons. -

Many water body identification methods have achieved good results in different application scenarios, but only a few for arid areas. An arid region water detection rule (ARWDR) was proposed by combining vegetation index and water index. Taking computing advantages of the Google Earth Engine (GEE) cloud platform, 56,284 Landsat 5/7/8 optical images in the TRB were used to detect open-surface water bodies and generated a 30-m annual water frequency map from 1992 to 2019. The interannual changes and trends of the water body area were analyzed and the impacts of climatic and anthropogenic drivers on open-surface water body area dynamics were examined.
