Notes on the Ground and Polished Stone Axes of East Africa
NOTES ON THE GROUND AND POLISHED STONE AXES OF EAST AFRICA. By MARY D. LEAKEY. During the last thirty years, a number of polished stone. axes have been discovered in East Africa. The majority of these have been chance finds made by farmers in the course of plough• ing or other agricultural activities, with the result that little reliable evidence has been recorded concerning associated mate• rial or stratigraphy. In spite of this regrettable lack of data, the five types of axe represented among the 22 complete specimens known to exist appear to be sufficiently interesting and their occurrence in Kenya and Tanganyika, of sufficient importance to merit a short description. Since the term "neolithic" is frequently applied to ground and polished stone implements and since it is permissible to assume for the present that the East African axes belong to this cultural phase, it may not be out of place to summarise the bases on which the term is applied in the area under review. It seems that for the greater part of Africa, excluding the Egyptian field, the characteristics of the neolithic stage in cultural development are generally recognised as being somewhat different to those understood for Europe. There, the combination of agriculture, the domestication of stock, pottery and the grinding and polishing of stone implements are usually considered essential criteria and are frequently found together in the same context. In East Africa, on the other hand, where our knowledge is still extremely scanty, although two or more of the above features may be present, all four have not hitherto been discovered in association. -

Black Sea/Mediterranean Environment Vol. 15: 47- 60 (2009) Freshwater and brackish water Malacostraca (Crustacea-Arthropoda) fauna of Sinop and Samsun and their ecology Sinop ve Samsun illeri tatlısu ve acısu Malacostraca (Crustacea-Arthropoda) faunası ve ekolojileri Mehmet Akbulut1*, M. Ruşen Ustaoğlu2, Ekrem Şanver Çelik1 1 Çanakkale Onsekiz Mart University, Fisheries Faculty, Çanakkale-Turkey 2 Ege University, Fisheries Faculty, Izmir-Turkey Abstract Malacostraca fauna collected from freshwater and brackishwater in Sinop and Samsun were studied from 181 stations between February 1999 and September 2000. 19 species and 4 subspecies belonging to 15 genuses were found in 134 stations. In total, 23 taxon were found: 11 Amphipoda, 6 Decapoda, 4 Isopoda, and 2 Mysidacea. Limnomysis benedeni is the first time in Turkish Mysidacea fauna. In this work at the first time recorded group are Gammarus pulex pulex, Gammarus aequicauda, Gammarus uludagi, Gammarus komareki, Gammarus longipedis, Gammarus balcanicus, Echinogammarus ischnus, Orchestia stephenseni Paramysis kosswigi, Idotea baltica basteri, Idotea hectica, Sphaeroma serratum, Palaemon adspersus, Crangon crangon, Potamon ibericum tauricum and Carcinus aestuarii in the studied area. Potamon ibericum tauricum is the most encountered and widespread species. Key words: Freshwater, brackish water, Malacostraca, Sinop, Samsun, Turkey Introduction The Malacostraca is the largest subgroup of crustaceans and includes the decapods such as crabs, mole crabs, lobsters, true shrimps and the stomatopods or mantis shrimps. There are more than 22,000 taxa in this group representing two third of all crustacean species and contains all the larger forms. *Corresponding author: [email protected] 47 Malacostracans play an important role in aquatic ecosystems and therefore their conservation is important. -

Kenyan Stone Age: the Louis Leakey Collection
World Archaeology at the Pitt Rivers Museum: A Characterization edited by Dan Hicks and Alice Stevenson, Archaeopress 2013, pages 35-21 3 Kenyan Stone Age: the Louis Leakey Collection Ceri Shipton Access 3.1 Introduction Louis Seymour Bazett Leakey is considered to be the founding father of palaeoanthropology, and his donation of some 6,747 artefacts from several Kenyan sites to the Pitt Rivers Museum (PRM) make his one of the largest collections in the Museum. Leakey was passionate aboutopen human evolution and Africa, and was able to prove that the deep roots of human ancestry lay in his native east Africa. At Olduvai Gorge, Tanzania he excavated an extraordinary sequence of Pleistocene human evolution, discovering several hominin species and naming the earliest known human culture: the Oldowan. At Olorgesailie, Kenya, he excavated an Acheulean site that is still influential in our understanding of Lower Pleistocene human behaviour. On Rusinga Island in Lake Victoria, Kenya he found the Miocene ape ancestor Proconsul. He obtained funding to establish three of the most influential primatologists in their field, dubbed Leakey’s ‘ape women’; Jane Goodall, Dian Fossey and Birute Galdikas, who pioneered the study of chimpanzee, gorilla and orangutan behaviour respectively. His second wife Mary Leakey, whom he first hired as an artefact illustrator, went on to be a great researcher in her own right, surpassing Louis’ work with her own excavations at Olduvai Gorge. Mary and Louis’ son Richard followed his parents’ career path initially, discovering many of the most important hominin fossils including KNM WT 15000 (the Nariokotome boy, a near complete Homo ergaster skeleton), KNM WT 17000 (the type specimen for Paranthropus aethiopicus), and KNM ER 1470 (the type specimen for Homo rudolfensis with an extremely well preserved Archaeopressendocranium). -

The Estimation of Lake Naivasha Area Changes Using of Hydro-Geospatial Technologies
http://dx.doi.org/10.4314/rj.v1i1S.3D The Estimation of Lake Naivasha Area Changes Using of Hydro-Geospatial Technologies A. Ruhakana Soil and Water Management Research Program Rwanda Agriculture Board, Huye, Rwanda [email protected] Abstract: Remote Sensing (RS) and Geographical Information System (GIS) were proved as new technology to intervene in monitoring, managing and protecting environmental resources among others lake and water reservoir are mostly anxious resources. The objective of the study was to estimate the surface area change of the lake Naivasha using RS, GIS techniques and hydrological modeling for the lake water balance. Landat images Thematic Mapper/Enhanced Thematic Mapper Plus (TM/ETM+) taken respectively in the same month of January 1986; 1995; 2003 and 2010 were the input data used to assess the different changes of the lake area on one hand. on other hand the spread sheet data set helped to build the hydrological model to estimate the long term lake Level fluctuation, the rainfall versus evaporation as in flow and out flow from the lake. The lake volume showed the dynamic of ground water to simulate the long-term fluctuation of the lake level. The lake area changes from the model were calculated from the spread sheet input data from 1986 to 2003 while the lake area changes from the Landsat images were calculated from 1986 to 2010. The comparative results from the area lake changes both from Landsat images and hydrological model confirmed the correlation results, 45.72 Km2 or 32.03 % in 2010 for the Landsat while the hydrological model estimated to 12km2 or 8% area reduction in 2003. -

(2018). Distribution and Diversity of Freshwater Crabs (Decapoda: Brachyura: Potamidae, Gec- arcinucidae) in Iranian Inland Waters. Aquatic Sciences and Engineering, 33(4): 110-116. ABSTRACT This article reviews the current knowledge of primary freshwater crabs (Decapoda, Brachyura) in Iranian inland waters, with the purpose of classifying the exact number of species, the threat sta- tus, and their distribution and diversity. Previous studies have reported that Iranian inland waters have eight freshwater crab species and there was no accurate information on the distribution of freshwater crab species in Iran. This review article describes that an additional six freshwater crab species, Potamon gedrosianum, P. magnum, P. mesopotamicum, P. ilam, Sodhiana blanfordi, and S. iranica, are also present in Iran. Therefore, there are 14 freshwater crab species currently known in Iran, which belong to two families (Gecarcinucidae and Potamidae). The genus Potamon is rep- resented by 11 species, and the genus Sodhiana is represented by 3 species (found in south and south east of Iran). In addition, this review presents a distribution map and the possible threats for each species. Keywords: Brachyura, decapoda, freshwater crabs, distribution, Iran INTRODUCTION ter swamps, stagnant ponds and rice fields, and even in tree hollows and leaf axils (Yeo et al., Primary freshwater crabs (Yeo et al., 2008, 2012) 2008; Cumberlidge et al., 2009). -
Application of Stable Isotope Geochemistry to Tracing Recharge and Flow Systems of Fluids in the Olkaria Geothermal Field, Kenya
Orkustofnun, Grensasvegur 9, Reports 2014 IS-108 Reykjavik, Iceland Number 24 APPLICATION OF STABLE ISOTOPE GEOCHEMISTRY TO TRACING RECHARGE AND FLOW SYSTEMS OF FLUIDS IN THE OLKARIA GEOTHERMAL FIELD, KENYA Melissa Nailantei Nkapiani Kenya Electricity Generating Company – KenGen P.O. Box 785 – 20117, Naivasha KENYA [email protected] ABSTRACT The long term success of any geothermal energy utilization depends on understanding groundwater movements and recharge areas. Water and steam condensates from subfields in the Olkaria geothermal field have been studied using the stable isotope ratios of hydrogen and oxygen to gain information on thermal fluid flow and to trace the origin of thermal waters. Isotope fractionation factors and mass balance equations were used to characterize reservoir fluid composition of wells in the area, assuming single stage steam separation. Comparison of the two methods yields coherent results for the oxygen- 18 isotope ratio, but the deuterium isotope ratio varies to some extent. The reservoir fluid isotope composition of the thermal waters suggests three recharge zones for the field: one from groundwater from the eastern Rift wall with δD about = -24‰; groundwater from the western Rift flank with δD about = -30‰; and the other from an evapo-concentrated source with δD about = 36‰. Qualitative interpretation of the available data suggests that the evapo-concentrated source largely contributes to the recharge of the East field, North East field and a part of the Domes field. Groundwater from the western rift wall recharges the West field of the area. The eastern Rift wall groundwater contributes to the southeast part of the Domes field. -
