Influence of cattle on browsing and grazing wildlife varies with rainfall and presence of megaherbivores
(The Ecological Society of America, 2017)In many savanna ecosystems worldwide, livestock share the landscape and its resources with wildlife. The nature of interactions between livestock and wildlife is a subject of considerable interest and speculation, yet ... -
Characterization of the nutritional quality of amaranth leaf protein concentrates and suitability of fish meal replacement in Nile tilapia feeds
(Elsevier, 2017)A number of leafy vegetables,their protein concentrates and hydrolasates are under evaluation as alternative protein ingredients to fish meal(FM)in aqua feeds. This study evaluated the nutritional characteristics and ... -
Fire disturbance disrupts an acacia ant–plant mutualism in favor of a subordinate ant species
(Wiley and sons, 2017-03)Although disturbance theory has been recognized as a useful framework in examining the stability of ant–plant mutualisms, very few studies have examined the effects of fire disturbance on these mutualisms. In myrmecophyt ... -
Spatial scales influence long-term response of herbivores to prescribed burning in a savanna ecosystem
(CSIRO PUBLISHING, 2017-04)Both wild and prescribed fire in savanna ecosystems influence habitat use by herbivores by creating or maintaining spatial and temporal heterogeneity in forage quality and vegetation cover. Yet little is known about how ... -
Allometric Equations for Estimating Silk Oak (Grevillea robusta) Biomass in Agricultural Landscapes of Maragua Subcounty, Kenya
(Hindawi International Journal of Forestry Research, 2018)Grevillea robusta is widely interplanted with crops in Maragua subcounty, a practice that enhances biomass quantities in farmlands. However, quick tools for estimating biomass of such trees are lacking resulting in ... -
The Role of Selected Environmental Factors on the Regeneration of (Ocotea usambarensis ) in Mount Kenya Forest, Kenya
(International Journal of Agriculture, Environment and Bioresearch, 2018)Despites the propagation efforts, density of Ocotea usambarensis has continued to diminish in the southern slopes of Mount Kenya. The species which is native in the montane forest is seldom on farm and found as remnant ... -
Challenges of Elephant Conservation: Insights from Oral Histories of Colonialism and Landscape in Tsavo, Kenya
(American Geographical Society, 2018)Understanding the reasons for conflict between elephants and people who live adjacent to conservation areas remains key to recruiting them as allies in preserving elephant populations. The Tsavo region of Kenya has become ... -
Developing a Forest Management Plan (DFMP) for Gatsibo District in the Eastern Province of Rwanda
(Scientific Research Publishing Inc., 2018)In support of conservation of its fragile land resource, the government of Rwanda has proposed the management of all forests in the country under a specific management plan. This assignment sought to develop a management ... -
Framing natural assets for advancing sustainability research: translating different perspectives into actions
(Springer, 2018)Sustainability is a key challenge for humanity in the context of complex and unprecedented global changes. Future Earth, an international research initiative aiming to advance global sustainability science, has recently ... -
Fishing power of conventionally harvested wetland baitworms compared to black soldier fly larvae as alternative baits in tropical artisanal hook fishery
(2018)Extensive and intensive, harvesting of earthworms and polychaetes from wetland substrate, for artisanal hook fishery, affect structural and functional integrity of these critical habitats. Cultured Black Soldier Fly larvae ... -
Influence of Adherence to Quality Management System Standards on Access to Water and Sanitation Services in Kenya
(IOSR Journal Of Humanities And Social Science, 2018-02)In Kenya, over 3,100 children die annually for using unsafe water and poor sanitation. In the 2015/2016 financial year, access to water in Kenya stood at 54% for urban and 51% for rural areas. This low access to water and ... -
Relationships Between Cattle and Biodiversity in Multiuse Landscape Revealed by Kenya Long-Term Exclosure Experiment
(Elsevier, 2018-05)On rangelands worldwide, cattle interact with many forms of biodiversity, most obviously with vegetation and other large herbivores. Since 1995, we have been manipulating the presence of cattle, mesoherbivores, and ... -

Globalization and Biodiversity Conservation Problems: Polycentric REDD+ Solutions
(MDPI, 2019-02-19)Noise barriers are the most widespread solution to mitigate noise produced by the continuous growth of vehicular traffic, thus reducing the large number of people exposed to it and avoiding unpleasant effects on health. ... -
Tree resprout dynamics following fire depend on herbivory by wild ungulate herbivores
(Journal of Ecology, 2019-04)1. Savanna tree cover is dynamic due to disturbances such as fire and herbivory. Frequent fires can limit a key demographic transition from sapling to adult height classes in savanna trees. Saplings may be caught in a ‘fire ...
