Mating Strategies in Solitary Aphid Parasitoids: Effect of Patch Residence Time and Ant Attendance
(Springer, 2012-01)
Mate finding and dispersal from the natal patch in parasitoid Hymenoptera are influenced by the availability of host resources and interactions with other organisms. We compared the mating behavior of three solitary aphid ...
Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(Cambridge University Press, 2012-04)
In the interaction between two ecologically-associated species, the population structure of one species may affect the population structure of the other. Here, we examine the population structures of the aphid Metopeurum ...
Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(2012-09)
In the interaction between two ecologically-associated species, the population
structure of one species may affect the population structure of the other. Here, we
examine the population structures of the aphid Metopeurum ...
Characterization of Uromyces appendiculatus isolates collected from snap bean growing areas in Kenya
(2012-11-02)
Bean rust (Uromyces appendiculatus (Pers.:Pers.) Unger var. appendiculatus) is one of the most
devastating and variable pathogens of common bean (Phaseolus vulgaris L.) worldwide that can cause
total crop loss. ...
A Comparison of the physico-chemical and bacteriological quality of greywater from water deficient households in Homabay Town and Githurai Estates in Kenya.
(Academic Journals, 2012)
Greywater, the untreated household wastewater that has not been contaminated by toilet waste, has been touted as a reliable all year-round source of water, especially in water scarce areas. Although it is commonly reused ...
Picocystis salinarum (Chlorophyta) in saline lakes and hot springs of East Africa.
(2012-01)
The occurrence of Picocystis salinarum in saline inland waters of East Africa was investigated using a polyphasic approach of small-subunit (SSU) rDNA phylogeny and light microscope observations. Recent studies have found ...
In vivo antimalarial and acute toxicity properties of hexane and chloroform extracts from Clausena anisata (Willd.) Benth
(2012)
Background: Drugs are an important tool for control of malaria. However, drug resistance is likely to compromise available antimalarial drugs with time. As a result, efforts are being directed towards discovery and development ...
Haloleptolyngbya alcalis gen. et sp. nov., a new filamentous cyanobacterium from the soda lake Nakuru, Kenya
(Springer, 2012)
The food web of the saline-alkaline Lake
Nakuru is dominated by the cyanobacterium Arthrospira
fusiformis as the primary producer and a huge
population of Lesser Flamingos as direct consumers.
However, the dense blooms ...
Genotypic diversity of Dictyosphaerium–morphospecies (Chlorellaceae, Trebouxiophyceae) in African inland waters, including the description of four new genera
(2012)
Trebouxiophytes of the Dictyosphaerium–morphotype from inland waters of Africa were studied using a polyphasic approach of SSU and ITS rDNA phylogeny, secondary structure of the ITS and observations made with a light ...
Potential of indigenous bradyrhizobia versus commercial inoculants to improve cowpea (Vigna unguiculata L. walp.) and green gram (Vigna radiata L. wilczek.) yields in Kenya
(2012)
Limited information is available on reduced cowpea (Vigna unguiculata L. Walp.) and green gram (Vigna radiata L.Wilczek.) yields in Kenya. Declining soil fertility and absence or presence of ineffective indigenous rhizobia ...
