Above-ground biomass and carbon stocks of different land cover types in Mt. Elgon, Eastern Uganda
(International Journal of Research on Land-use Sustainability, 2014)This research applied selected allometric models to estimate the total above ground biomass (TAGB) and carbon stocks in the different land-use/ land cover (LULC) types in Mt. Elgon National Park, in Eastern Uganda. The ... -
Abundance and Diversity of Native Forage Species in Pastoral Karamoja Sub-Region, Uganda
(African study monographs, 2015)Low input pastoral production systems rely exclusively on natural forage resources in space and time. Information on the abundance and diversity of such pastures is vital in improving livestock production and managing ... -
Abundance, movements and habitat use by African Grey Parrots (Psittacus erithacus) in Budongo and Mabira forest reserves, Uganda
(Journal of African Ornithology, 2007)Populations of African Grey Parrots are threatened by increased forest loss and the pet trade. Budongo forest reserve has, for over 60 years, been subjected to selective logging. Mabira forest reserve faces human pressures ... -
Active restoration facilitates bird community recovery in an Afrotropical rainforest
(Biological Conservation, 2016)Active restoration of rainforests is essential in enhancing the recovery of biodiversity in many tropical regions suffering from deforestation. However, the value of actively restored rainforests for birds is still ... -
Adaptation To Climate Change In Uganda: Evidence From Micro Level Data
(Global environmental change, 2011)This study employed data from the 2005/06 Uganda national household survey to identify adaptation strategies and factors governing their choice in Uganda's agricultural production. Factors that mediate or hinder adaptation ... -

Adaptive Party Choice of Low-Ranking Males in Fission–Fusion Dynamics of Chimpanzees in Kalinzu Forest Reserve, Uganda
(MDPI AG, 2022-08)Several studies have examined factors that regulate fission–fusion dynamics (FFD) in chimpanzee communities, such as receptive females, predation risks, and food availability. However, the effects of these factors vary ... -
Adsorbed complex and laboratory geotechnics of Quarry Dust (QD) stabilized lateritic soils
(Environmental Technology & Innovation, 2018)The effect of ordinary Portland cement, OPC+Quarry Dust, QD on the adsorbed moisture, diffused double layer (DDL), dielectric constant, density and repulsion potential (RP) of treated lateritic soil was investigated through ... -
African food insecurity in a changing climate: The roles of science and policy
(Food and Energy Security, 2019)African population is projected to double to 2.48 billion people by 2050. The population increase poses a serious challenge of increasing food supply to meet the future demand. This challenge is compounded by climate ... -
Age validation, growth and mortality of introduced Tilapia zillii in Crater Lake Nkuruba, Uganda
(Fisheries Management and Ecology, 2016)Periodicity and timing of opaque zone formation in otoliths of introduced redbelly tilapia, Tilapia zillii (Gervais), in Crater Lake Nkuruba, Uganda, were validated using marginal increment. Age and growth were assessed through ... -
An age-structured mathematical model for the within host dynamics of malaria and the immune system
(Springer, 2007)In the paper, we use a mathematical model to study the population dynamics of replicating malaria parasites and their interaction with the immune cells within a human host. The model is formulated as a system of age-structured ... -
Agricultural expansion as risk to endangered wildlife: Pesticide exposure in wild chimpanzees and baboons displaying facial dysplasia
(Science of the Total Environment, 2017)Prenatal exposure to environmental endocrine disruptors can affect development and induce irreversible abnormalities in both humans and wildlife. The northern part of Kibale National Park, a mid-altitude rainforest in ... -
Agrobiodiversity of homegardens in a commercial sugarcane cultivation land matrix in Uganda
(International Journal of Biodiversity Science, Ecosystem Services & Management, 2016)ABSTRACT Understanding biodiversity in homegardens embedded in landscapes dominated by commercial monoculture agriculture is critical for sustainable management of agrobiodiversity and meeting rural households’ needs ... -
Air pollution and mobility patterns in two Ugandan cities during COVID‑19 mobility restrictions suggest the validity of air quality data as a measure for human mobility
(Environmental Science and Pollution Research, 2022)We explored the viability of using air quality as an alternative to aggregated location data from mobile phones in the two most populated cities in Uganda. We accessed air quality and Google mobility data collected from ... -
Air quality management strategies in Africa: A scoping review of the content, context, co-benefits and unintended consequences
(Environment International, 2022)One of the major consequences of Africa’s rapid urbanisation is the worsening air pollution, especially in urban centres. However, existing societal challenges such as recovery from the COVID-19 pandemic, poverty, ... -
Alpine grassland palaeoecology of the Virunga Volcanoes, East Africa: A new phytolith record from Mt. Muhavura
(Quaternary International, 2017)This study presents a first attempt at using phytoliths from a high-altitude crater lake as a palaeoecological tool at a tropical montane site. Mt. Muhavura (4127 m asl) at the border of Uganda and Rwanda is part of the ... -
Amending Soils with Hydrogels Increases the Biomass of Nine Tree Species under Non-water Stress Conditions
(Clean–Soil, Air, Water, 2009)The classical aim of the application of super absorbent polyacrylate (SAPs) hydrogels is the prolonging of plant survival under water stress. Their effect on plant growth during non-water stress conditions is not known. ... -
Analyses of community willingness-to-pay and the influencing factors towards restoration of River Malaba floodplains
(Environmental Challenges, 2021)The high productivity of soils along River Malaba floodplains and various functions (like, transport and recreation) increase the desire for humankind settlement adjacent to floodplain corridors. However, human life and ... -
Analyses of Precipitation and Evapotranspiration Changes across the Lake Kyoga Basin in East Africa
