Abstract Aim Understanding the mechanisms controlling variation in species richness along environmental gradients is one of most important objectives ecology. Resource availability often considered as major driver animal diversity. However, ectotherms, temperature might play a predominant role it modulates metabolic rates and access animals to resources. Here, we investigate relative importance resource determining diversity pattern bees 3.6‐km elevational gradient. Location M ount K...
Forest fragmentation and selective logging are two main drivers of global environmental change modify biodiversity conditions in many tropical forests. The consequences these changes for the functioning forest ecosystems have rarely been explored a comprehensive approach. In Kenyan rainforest, we studied six animal-mediated ecosystem processes recorded species richness community composition all animal taxa involved processes. We used linear models formal meta-analysis to test whether...
Abstract Bee viral ecology is a fascinating emerging area of research: viruses exert range effects on their hosts, exacerbate impacts other environmental stressors, and, importantly, are readily shared across multiple bee species in community. However, our understanding communities limited, as it primarily derived from studies North American and European Apis mellifera populations. Here, we examined populations A . 11 9 countries, 4 continents Oceania. We developed novel pipeline to rapidly...
Properties and composition of honey are essential in providing information regarding their quality as well differentiation based on production region characteristics, e.g., floral sources. This paper presents physicochemical properties sources (botanical origin) 21 samples obtained from arid semiarid areas Kenya, specifically, West Pokot, Baringo, Kitui Counties. Physicochemical parameters which were analyzed to determine included moisture content, hydroxymethylfurfural (HMF), diastase...
Flower scarcity outside coffee flowering periods leads to a decline of pollinators' abundance and diversity possibly through death or migration. The objective this study was assess whether other plants within around farms act as alternative floral resources that may impact on pollinators flowers. Bee were assessed identified for period 27 months. Their examined organically conventionally managed in Kiambu District Kenya. This provides evidence 42 plant species from 19 families bees pollinate...
SummaryWe determined the diversity and abundance of native bees foraging on hedgerow flowers, documented plant species composition those hedgerows, from October 2008 to March 2009 at Kakamega, western Kenya. We made observations sectors located in five different land use types: Kakamega forest; roads; sugarcane plantations; maize/bean fields; grazing land. Our findings show that a high is supported by bee significantly (P < 0.05) differed across types. A total 82 belonging three families...
SummaryChanges in bee species richness and diversity were studied along a forest regeneration gradient seven sites Buyangu Nature Reserve, Kakamega Forest, Kenya. At each site, 12 belt transects of 100 m length 2 width established. The selected ranged from relatively undisturbed primary to late secondary forests, bush lands the surrounding farming areas. A total 4,485 individuals identified out 234 four families. Renyi Diversity Index was used analyse diversity. One-way measures ANOVA...
The study was conducted at Kiambu County in Kenya. aim of this to investigate whether pollination improves the coffee yield and quality processed terms taste aroma. Among parameters evaluated when grading for sale world market are berry weight cup quality. No previous work Kenya describes role bee pollinators enhancement yields Data on weights resulting from different levels organically grown were analyzed. Results indicate that benefits immensely pollinators. highest recorded open...
Bees provide important pollination services that maintain native plant populations and ecosystem resilience, which is critical to the conservation of rich endemic biodiversity Kaya forests along Kenyan Coast. This study examined bee composition floral resources from forest core surrounding farmlands around Muhaka forest. In total, 755 individual bees, representing 41 species three families were recorded: Apidae, Halictidae Megachilidae. Overall, Apidae most abundant with a proportion 76%...
Abstract Cotesia icipe Fernandez‐Triana & Fiaboe is a solitary koinobiont larval endoparasitoid, recently discovered in Kenya and new to science, that parasitizes select lepidopteran herbivores of amaranth. We investigated its host range on five commonly encountered amaranth defoliators. accepted, successfully aggressively parasitized the noctuid defoliators Spodoptera littoralis (Boisduval) exigua (Hübner), but failed parasitize Herpetogramma bipunctalis (F.), Spoladea recurvalis (F.)...
Stingless bees are important resources for pollination of crops, production medicinal honey and other products. However, throughout the developing countries in Africa, meliponiculture has received less attention beekeeping development programmes. Here, current situation stingless Uganda is assessed. First, bee species utilised their products were collected identified. Thereafter, economic benefits derived from Western Highlands agro-ecological zones with anecdotal reports analysed. The...
Pollination is an important ecosystem service in the maintenance of biodiversity and most importantly food production. on decline due to habitat loss, exotic species invasions, pollution, overharvesting, land use changes. This study analyzed abundance diversity flower visitors’ Ocimum kilimandscharicum Kakamega forest with increasing distance from edge. Data were collected through direct observation sweep netting. Six sites identified along two transects each 2.5 km long labeled A F....

Pollinators are important components of biodiversity and provide a key ecosystem service through pollination (Klein et al., 2007). Honeybees, mainly Apis mellifera, the most economically valuable pollinators for crop monocultures worldwide (Wantanabe, 1994), however, several high-value crops, e.g., coffee, is less effective than by local wild pollinator species 2003). Worldwide an increase farming accompanying increased dependency on services occurs. For instance, data from Brazil indicate...
