An Integrated Phylogeographic Analysis of the Bantu Migration
AN INTEGRATED PHYLOGEOGRAPHIC ANALYSIS OF THE BANTU MIGRATION by Colby Tyler Ford A dissertation submitted to the faculty of The University of North Carolina at Charlotte in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Bioinformatics and Computational Biology Charlotte 2018 Approved by: Dr. Daniel Janies Dr. Xinghua Shi Dr. Anthony Fodor Dr. Mirsad Hadzikadic Dr. Matthew Parrow ii ©2018 Colby Tyler Ford ALL RIGHTS RESERVED iii ABSTRACT COLBY TYLER FORD. An Integrated Phylogeographic Analysis of the Bantu Migration. (Under the direction of DR. DANIEL JANIES) \Bantu" is a term used to describe lineages of people in around 600 different ethnic groups on the African continent ranging from modern-day Cameroon to South Africa. The migration of the Bantu people, which occurred around 3,000 years ago, was influ- ential in spreading culture, language, and genetic traits and helped to shape human diversity on the continent. Research in the 1970s was completed to geographically divide the Bantu languages into 16 zones now known as \Guthrie zones" [25]. Researchers have postulated the migratory pattern of the Bantu people by exam- ining cultural information, linguistic traits, or small genetic datasets. These studies offer differing results due to variations in the data type used. Here, an assessment of the Bantu migration is made using a large dataset of combined cultural data and genetic (Y-chromosomal and mitochondrial) data. One working hypothesis is that the Bantu expansion can be characterized by a primary split in lineages, which occurred early on and prior to the population spread- ing south through what is now called the Congolese forest (i.e. -

Classroomsecrets.Com Differentiated Mountains
A Range of Ranges – Teacher Version Mountain ranges create some of the most spectacular scenery the earth has to offer. Breathtaking drops, sheer rock faces and snow-capped peaks are just some of the dramatic features of these spiny streaks on our planet’s surface. They come in all sizes and each mountain range is unique in terms of the flora and fauna it supports, the views it offers and the stories it has created. Several of the world’s most famous or most interesting mountain ranges have been marked on the map below. The numbers correspond with the boxes which follow; select a mountain range and then read on to discover all sorts of fascinating facts about it! M: Explain and evaluate the effect of the pun used in the title. The pun is on the word ‘range’. In its first use it means ‘a set of similar things’ but in the second it means ‘a set or sets of mountains’. The pun is effective because it shows wit and brings humour, both of which are incentives to keep reading. D: What are the ‘spiny streaks’ on our planet’s surface and why is this a good description? Mountain ranges. This is a good description because it conveys the jagged, spiky nature of a line of mountains, and also conveys that they are in a long line (streak). D: Why do you think the author has chosen to mark the extent of each mountain range on the map? To help people better visualise the size of the ranges. To make it clear exactly where the ranges start and stop. -

Evolutionary History, Genetic Diversity and Conservation
EVOLUTIONARY HISTORY, GENETIC DIVERSITY AND CONSERVATION IMPLICATIONS OF SELECTED AFRO-ALPINE TAXA BY CATHERINE ALOYCE MASAO A THESIS SUBMITTED IN FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY OF SOKOINE UNIVERSITY OF AGRICULTURE. MOROGORO, TANZANIA. 2012 ii EXTENDED ABSTRACT The tropical East African and Ethiopian mountains are famous for their exceptionally unique and high biodiversity. The flora on these mountains offers good examples of distinct adaptations to different altitudes as well as evolutionary differentiation, hence an ideal natural laboratory for studies on the dynamics of biodiversity. In this study the genetic diversity, evolutionary history and conservation implications of selected taxa occurring on these mountains were assessed. The objectives were to: 1) determine the level of intraspecific and interspecific genetic diversity of selected afro-alpine plant species, 2) explore the potential of AFLP markers for delimiting species and reconstructing the evolutionary relationships among some of the selected afro-alpine plants by comparing the results with those of previous morphological and molecular studies and 3) reconstruct the phylogeographic structure of the selected afro-alpine plant species. Data for this study were collected from 1 ha (10000 m2) plots on 14 mountains around the region. Amplified Fragment Length Polymorphism (AFLP) markers were used to characterize the genetic patterns of the selected taxa. Six hundred eighty nine individuals from 154 populations (13 species, a total of 1168 AFLP markers with 97.9% reproducibility) of giant lobelias, 33 individuals, nine populations (two species, 172 AFLP markers, 97.86% reproducibility) of Deschampsia, and 153 individuals 36 populations (458 AFLP markers, 97.4% reproducibility) of Koeleria capensis were successfully analyzed. -

Central African forests, when mapped at regional scale using remote sensing, are generally represented as one great homogeneous ‘forest’ land cover class. However, studies based on ecological and detailed forest inventories have identified spatial patterns of species diversity, functional traits and biomass, outlining the existence of several forest types. These forest types with contrasted structure and floristic composition have been described locally, but have been little or not mapped. A detailed vegetation map, representing the diversity of forest ecosystems at the scale of Central Africa is needed in order to plan and improve the management and conservation of these systems. Such a map has recently been produced, using a multi- temporal satellite approach, and validated with a multi-disciplinary scientific team of foresters and botanists with a strong field expertise. The study covers the entire forest area of the Congo basin (3.7 million of km²). -

A Rodent Described from the Mathews Range, Central Kenya
PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON 119(4):477-515. 2006. The status of Ototnys or estes dollmani Heller, 1912 (Muridae: Otomyinae), a rodent described from the Mathews Range, central Kenya Michael D. Carleton* and Ellen Schaefer Byrne (MDC) Department of Vertebrate Zoology, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560-0108, U.S.A., e-mail: [email protected]; (ESB) 4209 Lawn Avenue, Western Springs, Illinois 60558, U.S.A. Abstract.•Morphological and morphometric comparisons of Otomys orestes dollmani, known only from Mount Gargues in the Mathews Range, central Kenya, indicate that the taxon is a valid species distinct from other African forms under which it has been previously synonymized (O. irroratus, O. orestes, O. tropicalis). Based also on these comparisons, the morphological recognition and distribution of O. orestes (including thomasi Osgood) are further clarified in relation to O. tropicalis (including elgonis Wroughton) in Kenyan mountains and O. typus proper in Ethiopian highlands; another taxon relegated to junior synonymy within O. typus, O. uzungwensis Lawrence and Loveridge from south-central Tanzania, is resurrected to species. Certain traditional characters used in Otomys taxonomy, in particular molar lamination, demonstrate conservative patterns of variation that complement spatial structure derived from morphometric analyses of craniometric data and that vindicate their continued utility in delimiting species. We argue that uncritical emphasis of polytypic species, applied following the biological species concept during the latter 1900s, has led to chronic underestimation of species diversity of Otomys confined to the Afromontane Biotic Region in eastern Africa, in particular those populations that inhabit afroalpine environments. -
