Abstract: Sarthrura ayresi were endangered birds and their migratory routes are between Ethiopia and South Africa. Because of their population size, the International Union for the Conservation of Nature and Natural Resource(IUCN) regarded Sarothrura ayresi as critically endangered species. The study was aimed at assessing community awareness about ecology, conservation, and distribution and population census of WWFs in Berga Wetland. From 230 household owners living in four kebeles were use...
Abstract: The study was conducted at Babile Elephant Sanctuary (BES), to identify and document the list of woody species, and to analyze diversity, richness, evenness and population structural status of woody species and importance of provisioning ecosystem services. The diversity of plant species and population structure of woody species were analysed from 60 quadrats, each with 20 m x 20 m for trees and 5 m x 5 m for shrubs and climbers, using systematic sampling methods with three levels ...
Abstract: This study was conducted in Jallo Muktar forest, Western Hararghe Zone, Ethiopia. Data were collected from December 2018 to January 2019 with the aim of woody species diversity and carbon stock estimation along altitudinal gradients. Transects were laid out on three altitudinal gradients namely lower altitude (LA:2060 – 2410 m.a.s.l.), middle altitude (MA: 2411– 2760 m.a.s.l.) and upper altitude (UA: 2761 -3017 m.a.s.l). A total of 60 sample plots of 20m×20m (400 m2) in each a...
Abstract: Land cover and climate changes remain the greatest challenges to the conservation of montane birds; consequently, understanding the effects of these threats can inform conservation efforts. Conservation of birds demands data, not only for the present status but also for projections of future status and vulnerability. This study investigated the impacts of land cover and climate changes on the distribution of bird species of concern in Malawi. The CA-MC model was used to predict fut...
Abstract: This study was conducted in Awash National Park, Ethiopia, to analyse woody species composition and estimate carbon stock potential of woody species in different vegetation types. A total of 80 quadrats of 20m x 20 m, 5m x 5m and 1m x 1m with 16 horizontal transect lines were used to collect information on tree, shrub, and litters and soil respectively in the four vegetation types. A total of 52 woody species belonging into 23 families with stem number of 1369 individual/ha were re...
Abstract: This study was conducted at Muhabura Volcano, in Volcanoes National Park, Northern Rwanda, to determine woody species diversity and carbon stock potential of woody species along altitudinal gradients. The study area was stratified into three strata based on physical appearance of vegetation and elevation gradients: low altitude 2502-2882 m a.s.l, middle altitude which lies between 2883-3109 m a.s.l and upper altitude which lies between 3110-4127 m a.s.l. A total of 60 plots of 20m ...
Abstract: This study was focused on the diversity and conservation status of non- timber forest products (NTFPs) in Sera forest with the objective of identifying and documenting diversity of plant species used as NTFPs and their conservation status. The study applied a combination of plant ecological and ethno botanical methods. A preferential systematic sampling method was used to collect vegetation data from 50 plots of 20 m x 20 m for all woody species and 2x2 m subplots inside the large ...
Increasing population in the developing world and associated needs for agricultural production, human settlement and industrialization have led to massive destruction of tree resources through deforestation and degradation of tree landscape. Countries have restricted access to forest resources by establishing forest reserves, causing communities to depend widely on Trees Outside the Forest (TOF). Therefore, TOF are diminishing and with them their protective and productive functions due to ove...
ABSTRACT Cichlids are subject to a wide range of diseases and parasites. Previously studies were conducted on fish parasites on the Okavango Delta, Botswana. This thesis is the first on fish parasites in the Kavango River, Namibia. The study aims to identify parasites occurring on commercially farmed fish i.e.: Oreochromis andersonii, Tilapia rendalli and Serranochromis robustus and to determine if these parasites may have potential threat to aquaculture and humans. For the purpose of identif...
ABSTRACT Approximately 6.6% of Hardap Region has unsafe drinking water according to WHO (2018) guidelines. Consuming this water can cause serious illness. Three filters, namely the bucket filter, sand filter, and charcoal filters were constructed and tested for physico-chemical and bacteriological removal efficiencies. More than 500 000 people in developing countries use filters to treat drinking water. Regardless of this positive implementation, there is limited knowledge to improve its desi...
ABSTRACT The genus Moringa comprises of thirteen (13) species of trees and shrubs, widely distributed in the tropical and subtropical regions. For its size, this genus is one of the phenotypically varied group of angiosperms whose members are mostly sought after for nutritional, nutraceutical and industrial uses. The aim of this study was to assess the species boundaries of Moringa ovalifolia in Namibia by using the nuclear Internal Transcribed Spacer (ITS) sequenced data analysis. A total of...
ABSTRACT Tree ring studies, known as dendrochronology, have been an important tool for studying climate variations since the beginning of the 1900s. This is because the information preserved in tree rings of most tree species for many years serves as environmental archives for both abiotic and biotic factors, tools that can be used to monitor climate changes. This study was the first to compare the growth rings of Dichrostachys cinerea and Senegalia mellifera along a rainfall gradient to inf...
Abstract Black rhinoceroses (Diceros bicornis) have been extirpated from most of their historic range with the remaining individuals (ca. 5200) living in geographically isolated populations. Management priorities include creating new populations whilst maintaining genetic diversity and promoting gene flow between existing isolated populations. Such objectives are however currently hindered by a lack of comparative/reference data on levels of diversity, relatedness and inbreeding in a large, f...
