Biodiversity and Ecology of Afromontane Rainforests with Wild Coffea Arabica L
Feyera Senbeta Wakjira (Autor) Biodiversity and ecology of Afromontane rainforests with wild Coffea arabica L. populations in Ethiopia https://cuvillier.de/de/shop/publications/2260 Copyright: Cuvillier Verlag, Inhaberin Annette Jentzsch-Cuvillier, Nonnenstieg 8, 37075 Göttingen, Germany Telefon: +49 (0)551 54724-0, E-Mail: [email protected], Website: https://cuvillier.de General introduction 1 GENERAL INTRODUCTION 1.1 Background The term biodiversity is used to convey the total number, variety and variability of living organisms and the ecological complexes in which they occur (Wilson 1988; CBD 1992; Rosenzweig 1995). The concept of biological diversity can be applied to a wide range of spatial and organization scales, including genetics, species, community, and landscape scales (Noss 1990; Austin et al. 1996; Tuomisto et al. 2003). It is becoming increasingly apparent that knowledge of the role of patterns and processes that determine diversity at different scales is at the very heart of an understanding of variation in biodiversity. Processes influencing diversity operate at different spatial and temporal scales (Rosenzweig 1995; Gaston 2000). A variety of environmental events and processes, including past evolutionary development, biogeographic processes, extinctions, and current influences govern the biodiversity of a particular site (Brown and Lomolino 1998; Gaston 2000; Ricklefs and Miller 2000). Biodiversity is valued and has been studied largely because it is used, and could be used better, to sustain and improve human well-being (WWF 1993; WCMC 1994). However, there has been a rapid decline in the biodiversity of the world during the past two to three decades (Wilson 1988; Whitmore and Sayer 1992; Lugo et al. -
Climate Forcing of Tree Growth in Dry Afromontane Forest Fragments of Northern Ethiopia: Evidence from Multi-Species Responses Zenebe Girmay Siyum1,2* , J
Siyum et al. Forest Ecosystems (2019) 6:15 https://doi.org/10.1186/s40663-019-0178-y RESEARCH Open Access Climate forcing of tree growth in dry Afromontane forest fragments of Northern Ethiopia: evidence from multi-species responses Zenebe Girmay Siyum1,2* , J. O. Ayoade3, M. A. Onilude4 and Motuma Tolera Feyissa2 Abstract Background: Climate-induced challenge remains a growing concern in the dry tropics, threatening carbon sink potential of tropical dry forests. Hence, understanding their responses to the changing climate is of high priority to facilitate sustainable management of the remnant dry forests. In this study, we examined the long-term climate- growth relations of main tree species in the remnant dry Afromontane forests in northern Ethiopia. The aim of this study was to assess the dendrochronological potential of selected dry Afromontane tree species and to study the influence of climatic variables (temperature and rainfall) on radial growth. It was hypothesized that there are potential tree species with discernible annual growth rings owing to the uni-modality of rainfall in the region. Ring width measurements were based on increment core samples and stem discs collected from a total of 106 trees belonging to three tree species (Juniperus procera, Olea europaea subsp. cuspidate and Podocarpus falcatus). The collected samples were prepared, crossdated, and analyzed using standard dendrochronological methods. The formation of annual growth rings of the study species was verified based on successful crossdatability and by correlating tree-ring widths with rainfall. Results: The results showed that all the sampled tree species form distinct growth boundaries though differences in the distinctiveness were observed among the species. -

Corrosion Map of South Africa's Macro Atmosphere
Corrosion map of South Africa’s macro atmosphere AUTHORS: Darelle T. Janse van Rensburg1,2 The first atmospheric corrosion map of South Africa, produced by Callaghan in 1991, has become outdated, Lesley A. Cornish1 because it primarily focuses on the corrosivity of coastal environments, with little differentiation given Josias van der Merwe1 concerning South Africa’s inland locations. To address this problem, a study was undertaken to develop AFFILIATIONS: a new corrosion map of the country, with the emphasis placed on providing greater detail concerning 1School of Chemical and Metallurgical South Africa’s inland regions. Here we present this new corrosion map of South Africa’s macro atmosphere, Engineering and DST-NRF Centre of Excellence in Strong Materials, based on 12-month corrosion rates of mild steel at more than 100 sites throughout the country.

Distribution, Habitat Structure and Troop Size in Eastern Cape
Distribution, habitat structure and troop size in Eastern Cape samango monkeys Cercopithecus albogularis labiatus (Primates: Cercopithecoidea) A dissertation submitted to the Department of Zoology and Entomology in fulfilment of the requirements for the degree of Master of Science in Zoology the University of Fort Hare by Vusumzi Martins Supervisors: Dr Fabien Génin and Prof. Judith Masters GENERAL ABSTRACT The samango monkey subspecies Cercopithecus albogularis labiatus is endemic to South Africa, and known to occur in Afromontane forests. There has been a major decline in this subspecies, exceeding 30% in some populations over the past 30 years, primarily as a result of the loss of suitable habitat. A second samango subspecies, C. a. erythrarchus, occurs near the northern border of South Africa, mainly in coastal lowland forest, and the distributions of the two subspecies do not overlap. C. a. labiatus was thought to be confined to Afromontane forests, but the study described here focused on C. a. labiatus populations that were recently identified in the Indian Ocean Belt forests near East London. I undertook to assess the distribution of C. a. labiatus in the Eastern Cape, to evaluate the habitat structures of the Afromontane and Indian Ocean coastal belt forests, and to understand the effect these habitats have on essential aspects of the socio-ecology of the C. a. labiatus populations. Distribution surveys were conducted in protected areas throughout the Eastern Cape, and samango monkeys were found to be present within forest patches in the Amatola Mountains, Eastern Cape dune forests and the Transkei coastal scarp forests. The sizes and composition of two troops were assessed: one troop in the Amatole forests and one in the Eastern Cape dune forests. -

PhytoKeys 65: 1–14. doi: 10.3897/phytokeys.65.8679 Abstract Kumbira forest is a discrete patch of moist forest of Guineo-Congolian biome in Western Angola central scarp and runs through Cuanza Norte and Cuanza Sul province. The project aimed to document the floristic diversity of the Angolan escarpment, a combination of general walk-over survey, plant specimen collection and sight observation was used to aid the characterization of the vegetation. Over 100 plant specimens in flower or fruit were collected within four identified vegetation types. The list of species in- cludes two new records of Guineo-Congolian species in Angola, one new record for the country and one potential new species. Keywords Kumbira forest, Guineo-Congolian, floristic diversity Introduction Angola lies almost wholly within the southern zone of tropical grassland, bounded by tropical rain forest of the Congo in the north and by the Kalahari Desert in the south (Shaw 1947). -
Sonar Surveys for Bat Species Richness and Activity in the Southern Kalahari Desert, Kgalagadi Transfrontier Park, South Africa

Adams 1,* and Gary Kwiecinski 2 1 School of Biological Sciences, University of Northern Colorado, Greeley, CO 80639, USA 2 Department of Biology, University of Scranton, Scranton, PA 18510, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-970-351-2057 Received: 27 March 2018; Accepted: 10 September 2018; Published: 18 September 2018 Abstract: Kgalagadi Transfrontier Park is located in northwestern South Africa and extends northeastward into Botswana. The park lies largely within the southern Kalahari Desert ecosystem where the Auob and Nassob rivers reach their confluence. Although these rivers run only about once every 100 years, or shortly after large thunderstorms, underground flows and seeps provide consistent surface water for the parks sparse vegetation and diverse wildlife. No formal studies on bats have previously occurred at Kgalagadi. We used SM2 + BAT ultrasonic detectors to survey 10 sites along the Auob and Nassob rivers from 5–16 April 2016. The units recorded 3960 call sequences that were analyzed using Kaleidoscope software for South African bats as well as visual determinations based on call structure attributes (low frequency, characteristic frequency, call duration, and bandwidth). We identified 12 species from four families: Rhinolophidae: Rhinolophus fumigatus. Molossidae: Chaerephon pumilus, and Sauromys petrophilus, Tadarida aegyptiaca; Miniopteridae: Miniopteris schreibersi (natalensis), Vespertilionidae: Laephotis botswanae, Myotis tricolor, Neoromicia capensis, N. nana, Pipistrellus hesperidus, Scotophilus dinganii, and S. viridus. The most abundant species during the survey period was N. capensis. We also used paired-site design to test for greater bat activity at water sources compared to dry sites, with dry sites being significantly more active.
