In East Africa, honey bees (Apis mellifera) provide critical pollination services and income for small-holder farmers rural families. While bee populations in North America Europe are decline, little is known about the status of Africa. We initiated a nationwide survey encompassing 24 locations across Kenya 2010 to evaluate numbers sizes colonies, assess presence parasites (Varroa mites Nosema microsporidia) viruses, identify quantify pesticide contaminants hives, assay levels hygienic...
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...
The western honey bee originated in Asia before adaptively radiating into Africa and Europe.
In Africa, humans evolved as honey hunters of bee subspecies adapted to diverse geographical regions. Beekeeping today is practiced much it was when Africans moved from hunting beekeeping nearly 5,000 years ago, with beekeepers relying on seasonally available wild bees. Research suggests that populations are resilient, able resist diseases and novel parasites. Distinct biomes, well environmental pressures, shaped the behavior biology these bees in turn influenced how indigenous developed. It...
1 Abstract In African countries various tree spcies are a key part in Non Timber Forest Production (NTFP) economy, be it for fruit, resin collection or medicinal use. Among these species Acacias play an important role the arid and semi-arid dry-lands over Africa. this study we explore potential of BioGeoChemical Modelling techniques to assess growth peformance Acacia ocurrences within their natural environment, where they only may persist against rain-fed grassland vegetation when having...
Abstract Lukenya University has recently begun implementing a Ten Million Tree Growing Initiative, as part larger national multi-institutional country-wide tree growing program. In this paper we describe the methods used far selection and planting itself. Note that most of trees are not planted directly by institution given to farmers plant on their land, with instruction how choose location technically perform maintenance ensure greater success for environment surrounding it. This knowledge...
With the development of inexpensive, high-throughput sequencing technologies, it has become feasible to examine questions related population genetics and molecular evolution non-model species in their ecological contexts on a genome-wide scale. Here, we employed newly developed suite integrated, web-based programs dynamics signatures selection across genome using several well-established tests, including F ST, pN/pS, McDonald-Kreitman. We applied these techniques study populations honey bees...
Abstract A study was carried out in K akamega forest, the western region of enya, to evaluate effectiveness stingless bee H ypotrigona gribodoi ( M agretti, 1884) on pollination green pepper. Three treatments were applied and consisted self‐pollination, by feral pollinators open field . a net cage. The differences fruit yield seed quality compared among treatments. Flowers pollinated produced heaviest fruits with highest numbers followed lastly self‐pollinated flowers. Moreover, seeds...
The honey consumed in most of Africa is harvested from traditional hives and processed using methods. This work presents the quality characteristics samples (n = 72) methods on sale various important beekeeping zones Kenya: West Pokot, Baringo, Mwingi, Tana, North Kinangop, Mbeere, Nandi Hills, Mida Creek, Kakamega Taita. was compared to international standards as proposed Codex Alimentarius. markers analyzed were moisture, hydromethylfurfural (HMF), sugar content, diastase, proline free...
Varroa-specific hygienic behavior is a hereditary trait of honey bee (Apis mellifera), which supports resistance to Varroa destructor. This study investigated the response Apis mellifera scutellata Varroa-infested worker brood cells in Kenya, East Africa. Uncapping, removal brood, and disappearance introduced mite were recorded total 690 into live mites introduced. We high proportion untouched controls (median, 80%) compared manipulated had been 12.5%) with significant difference (GLMM, p <...
Current trends in global honeybee population changes have been linked to drastic declines populations caused by complex interactions between pathogens, arthropod pests such as Varroa, pesticides, stress and habitat loss. Although substantial information exists for this sudden decline Europe North America, Africa the effect of threat continues draw debate. Despite recent reports showing presence V. destructor mites across continent, knowledge on pathogens associated with bees mite various...
Landscape fragmentation and habitat loss at multiple scales directly affect species abundance, diversity, productivity. There is a paucity of information about the effect landscape structure diversity on honey bee colony strength in Africa. Here, we present new insights into relationship between metrics such as patch size, shape, connectivity, composition, configuration (Apis mellifera) characteristics. Remote-sensing-based variables were linked to typical highly fragmented smallholder...

Nosemosis is a parasitic disease caused by microsporidian pathogens of the genus Nosema infecting both Western honey bee, Apis mellifera, and Asian bee cerana. The may adversely affect colonies eventually result in high losses apiculture agriculture. We determined species bees their prevalence two islands Comoros Archipelago (Grande Comore (GCO) Mohéli (MOH)) Southwest Indian Ocean. In Comoros, beekeeping largely traditional practiced at subsistence-level, including hunting. Five foragers...
Although the effects of numerous factors (such as age grafted larvae, supplemental feeding and mating) have been studied on honey bees Europe America, they remain unknown for African bee races. To bridge this gap, a study was undertaken at icipe Karura forest apiaries in Kenya to determine effect larval morphometrics oviposition Apis mellifera scutellata queens. Queens were reared 12 colonies with two regimes, fed not fed. Five groups: 6, 12, 24, 36, 48 h old, from each colony. We measured...
The Kutai National Park (KNP) which is located in East Regency on Kalimantan Province endowed with numerous pristine of mangrove forest. However, related information to the species composition and diversity KNP still scanty. Twenty-one were recorded using quadratic transects survey method (total plot area 1.7 ha). Main communities Avicennia lanata, A. marina, Bruguiera gymnorrhysa, B sexangular, Ceriops tagal, Rhizophora apiculata, R. mucronata Sonneratia Alba. Mangrove density was reached...

Abstract Background Honey bees are the principal commercial pollinators. Along with other arthropods, they increasingly under threat from anthropogenic factors such as incursion of invasive honey bee subspecies, pathogens and parasites. Better tools needed to identify subspecies. Genomic data for economic ecologically important organisms is increasing, but in its basic form practical application address ecological problems limited. Results We introduce HBeeID a means bees. The tool utilizes...
