ABSTRACT In 2018, between February and June we conducted a study on HLCC around Tarangire NP and observed that agricultural development activities and human population growth have destructed suitable habitats previously occupied by wildlife. This situation had intensified HLCC in sub- Saharan Africa as a result carnivores population is declining due to human revenges for livestock depredated and human attacked. In Tanzania, HWC have been well documented especially in Serengeti NP and Selous...
ABSTRACT Studies on deadwood (DW) production and nutrient recycling through decomposition by termites in semi arid ecosystems are scarce and thus given less consideration in forest management. A study was conducted at Chimwaga forest patch of UDOM to estimate the amount of DW produced by A. tortilis and A. nilotica as well as the decomposition rate by termites during dry and rain seasons. Both random and systematic sampling techniques were adopted coupled with a completely randomized design ...
ABSTRACTS Urbanization developments results in the loss and fragmentation of habitat, which can significantly alter animal communities. Wildlife species occupying higher trophic levels, such as mammalian carnivores may be especially affected by habitat alteration and concomitant losses of cover and prey. Tanzania has high carnivore diversity, 35 species or more, but relatively little is known about carnivore communities outside protected areas or the effects of urbanization on carnivore comm...
ABSTRACT The optimum productivity of local chicken population is limited by poor housing management, poor feeding and nutrition, incidences of diseases and lack of appropriate breeding strategies. A study was carried out in different districts of Dodoma and Singida regions of central Tanzania to characterize local chicken ecotypes based on specific objectives; (1) To identify qualitative traits, and (2) to determine quantitative traits of selected local chicken ecotypes. Chickens indigenous t...
ABSTRACT The objective of the study was to assess impact of anthropogenic activities on sustainability of the natural forest fragments of Makuwe-Gando and Mtambwe south forest patches, Wete District of Pemba Island. The study was carried out based on the following specific objective; (1) to identify important forest goods and services derived from MGFP and MSFP of Wete district in Pemba Island; (2) to identify type and nature of anthropogenic activities in MGFP and MSFP of Wete district in P...
ABSTRACT A study was carried out to assess effects of sand mining on land degradation and plant species diversity in North „B‟ district, Zanzibar based on specific objectives to: (1) investigate community perception on sand mining, (2) asses the impact of sand mining on socio-economic activities among small holder farmers,(3) determine effect sand mining on land degradation. The study also aimed (4) to determine effect of sand mining on plant species biodiversity, (5) to identify importa...
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 The study to assess livestock depredation by spotted hyena was conducted in six villages surrounding Ruaha National Park which were systematically selected along the gradient of distance from the park. The closest village was Tungamalenga that is 37 km from the park while other villages were: Makifu village (39km), Mapogolo village (42km), Mahuninga village (49km), kitisi village (50km) and Idodi village 52km. Data collection involved 121 households that were selected through snowbal...
ABSTRACT A study was conducted in Nanyala Village, Mbozi District, southwestern Tanzania to determine the effects of small-scale limestone mining on floristic composition and species diversity of shrubs and herbs, and on plant community characteristics. A stratified random sampling technique was adopted. One hundred plots (5 × 5 m) and 500 plots (0.5 × 0.5 m) were established systematically in each stratum at both mined and unmined sites for sampling shrubs and herbs, respectively. The tot...
ABSTRACT Three experiments were conducted at AVRDC-ESA, Arusha-Tanzania in 2014/2015, to assess performance of Tanzanian commercial tomato cultivars„Tanya‟, „Tengeru 2010‟, and „Tengeru 97‟ grafted on the tomato rootsock lines („BF OKITSU 101‟, „HAWAII 7996‟ and „R3034-3-10-N-UG‟) with specific objectives: (1) to determine survival rate of the grafted seedlings; (2) to evaluate the effect of grafting on vegetative growth (days to 50 % flowering (ND50FL), fruit maturit...
ABSTRACT The efficiency of energy sources used by households was experimentally determined in this study. To achieve the study objectives, comparison was done between different energy sources such as LPG, electricity, charcoal and firewood. The comparison was determined by observing efficiency of energy sources and the subsequent cost. The tools like experimentation, questionnaire, interviews, and documentary data were used. Four types of energy sources were employed to cook 250g of beans. Th...
