Behavioral patterns and responses to human disturbance of wild somali ostrich in Samburu, Kenya
(2016)Somali ostrich has suffered a drastic decline in its population and range mainly due to hunting over the years for meat, skin and feathers. Urgent conservation measures should therefore be taken to reverse this trend ... -
Agrobiodiversity conservation enhances food security in subsistence-based farming systems of Eastern Kenya
(2016-09-15)Background Globally, there is great concern about expanding agricultural activities due to their impact in the conservation of agrobiodiversity. African continent is known for its richness in biodiversity. In Kenya, there ... -
Potential of native rhizobia in enhancing nitrogen fixation and yields of climbing beans (Phaseolus vulgaris L.) in Contrasting Environments of Eastern Kenya
(2017-03-13)Climbing bean (Phaseolus vulgaris L.) production in Kenya is greatly undermined by low soil fertility, especially in agriculturally prolific areas. The use of effective native rhizobia inoculants to promote nitrogen fixation ... -
Genetic Characterization and Diversity of Rhizobium Isolated from Root Nodules of Mid-Altitude Climbing Bean (Phaseolus vulgaris L.) Varieties.
(2018-05-15)The increasing interest in the use of rhizobia as biofertilizers in smallholder agricultural farming systems of the Sub-Saharan Africa has prompted the identification of a large number of tropical rhizobia strains and led ... -
Effects of Auxin and Source of Explants on Callus Induction of Tropical Maize
(2012)Induction of callus from explants is a critical process in regeneration, micropropagation and transformation of plants. Formation of callus from plant tissues on culture is affected by different factors. This study sought ... -
Enhanced Utilization of Biotechnology Research and Development Innovations in Eastern and Central Africa for Agro-ecological Intensification
(Springer, 2014-07-16)The Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) through its Agrobiodiversity and Biotechnology Programme is enhancing the utilization of biotechnology research and development ... -
Occurrence and abundance of plant parasitic nematodes in cabbage-based cropping systems in Kenya.
(2014-10)A survey was conducted to determine the incidences of plant parasitic nematodes (PPN) and factors enhancing population build-up in cabbage (Brassica oleracea L. var capitata)-based cropping system in selected agro-ecological ... -
Effector gene vap1based DGGE fingerprinting to assess variation within and among Globodera species and populations.
(2019-11-12)Population-level genetic tools to study the epidemiology of potato cyst nematodes (PCN) are needed to evaluate their adaptive potential and validate management strategies. The effector gene vap1 is essential in early ... -
Reproduction of Globodera pallida on tissue culture-derived potato plants and their potential use in resistance screening process.
(2019-06-17)Globodera pallida infestation on potato is responsible for huge yield losses globally. Screening of potato germplasm for resistance to the nematode at the early stages of a breeding programme can significantly enhance ... -
Reproduction and life history traits of a resistance breaking Globodera pallida population
(Society of Nematologists, 2019-12-05)The main and most efficient measure to control potato cyst nematode (PCN) is the use of resistant cultivars. German and Dutch National Plant Protection Organizations (NPPOs) recently reported the emergence of Globodera ... -
Novel Sources of Witchweed (Striga) Resistance from Wild Sorghum Accessions
(2017-02)Sorghum is a major food staple in sub-Saharan Africa (SSA), but its production is constrained by the parasitic plant Striga that attaches to the roots of many cereals crops and causes severe stunting and loss of yield. ... -
Habits of a highly successful cereal killer, Striga
(PLOS Pathogens, 2018-01-11)Striga is a highly successful pathogen of cereal crops in sub-Saharan Africa. Also known as witchweed, Striga is an attractive parasitic plant whose beautiful flowers belie its noxiousness. Most cultivated cereals, including ... -
Modifying Surber sampling technique increases capture of freshwater crabs in African upland streams. Inland Waters. 2:11-15
(2017-04-03)We compared 2 methods for sampling the freshwater crab Potamonautes odhneri (Colosi) in Kenyan streams: standard Surber sampling, in which a sample is taken over a period of several minutes; and rapid Surber sampling, ... -
Parasites of Commercially Important Fish from Lake Naivasha, Rift Valley, Kenya.
(springer, 2014-01)In Lake Naivasha, the common carp Cyprinus carpio L. 1758 was accidentally introduced from fish farms adjacent to River Malewa in 1999 and now forms the bulk of the total fish caught. Since its introduction, no study has ... -
An Inventory and Assessment of Exotic and Native Plant Species Diversity in the Kenyan Rangelands:-Case Study of Narok North Sub-County.
(2015)A botanical inventory and diversity of exotic and native species was assessed in the rangeland of Narok North sub-County, Kenya. A total of 72 species were recorded, composed of 64 species of trees and shrubs and eight ...
