Item Light Rainfall and Plant Survival in E. Africa II. Dry Grassland Vegetation(British Ecological Society, 1962) Glover, P.E.; Glover, J.; Gwynne, M.D.; Kenya Veterinary Department; East African Agriculture and Forestry Research Organization; University of Oxford; Kenya Veterinary Department; East African Agriculture and Forestry Research Organization; University of OxfordRain-water penetration of the soil beneath a number of dry grassland communities was examined a few hours after a light shower in Kenya Masailand. It was found that for the particular communities studied, the type of soil present and the amount of rainfall, the depth of rain-water penetration is approximately equal to the height of the plant plus the normal penetration of the shower into the bare soil. The sectional area of the wet soil mass beneath each vegetation clump is also approximately equal to the sectional area of the clump showing above ground plus an area corresponding to the amount which would have fallen there had there been no plant cover. It is considered that in the overgrazed dry grassland parts of Kenya Masailand, stem-flow and rain-water penetration around trees of B. aegyptiaca may now be playing a part in changing the character of the local vegetation. It is also suggested that leaf catchment-stemflow systems may be involved in the maintenance of grassland vegetation patterns noted in other regions by other workers.Item Masai and Kipsigis Notes on East African Plants(1966) Glover, P.E.; Joyce, S.; Gwynne, M. D.The information contained in this series of papers was collected during the course of an ecological survey of the Narok District of Kenya Masai land. The survey was initiated by Dr. F. Fraser Darling and carried out under the auspices of the Conservation Foundation, New York.Item Masai and Kipsigis Notes on East African Plants: Part I—Grazing, Browse, Animal Associated and Poisonous Plants.(1966) Glover, P.E.; Stewart, J.; Gwynne, M.D.; E.A.A.F.R.O., Muguga, Kikuyu, KenyaThe information contained in this series of papers was collected during the course of an ecological survey of the Narok District of Kenya Masailand. The survey was initiated by Dr. F. Fraser Darling and carried out under the auspices of the Conservation Foundation, New York.Item Masai and Kipsigis Notes on East African Plants: Part II—Domestic Uses of Plants.(1966) Glover, P.E.; Stewart, J.; Gwynne, M.D. ; E.A.A.F.R.O., Muguga, Kikuyu, KenyaPart II includes edible plants, dye plants and plants used for string and rope. The list in part III is grouped under disorders. All groups are subdivided according to plant families.Item Rain-Water Penetration in British Somaliland Soils(1950) Glover, P.E.Whilst examine the roots of Acacia socolrana Balf.f. at Ged Dobo in the Guban (Coastal Plain of British Somali land) it was observed that even as long as four days after rain had fallen a clearly visible and well-defined moisture penetration line could be seen on the freshly dug soil profiles, by the fact that the soil above it appeared wetter and darker than that beneath it. This suggested that there might be a relationship between the top cover, the root growth form of plants, and the visible penetration depths of rain-water into the soil. The experiments described below show that the original idea was in general correct, but a striking correlation between denuded ground and depth of moisture penetration is also shown. Since these experiments were undertaken in the process of a survey of the "Devastated Areas of British Somali land the importance of the results in showing the effect of denudation on run-off, and penetration of rain-water could not be overlooked.Item A Review of Recent Knowledge of the Ecology of the Main Vectors of Trypanosomiasis(1963) Langridge, W.P.; Kernaghan, R.J.; Glover, P.E.; Department of Veterinary , ministry of agriculture and Animals; WHO Expert Committee on Tryponosomiasis , Tsetse Survey and Control, Department of Veterinary , Ministry Of Agriculture and Animal Husbandry , Kabete Kenya, Ministry Of Health Northern NigeriaIn this survey of recent ecological research on the main vectors of trypanosomiasis in those countries of East, Central and West Africa that are not predominantly French-speaking, the authors, after outlining the distribution of tsetse flies and the type of country in which they occur, discuss the direct and indirect effects of climate on these insects—particularly on their physiological water balance and on pupal fat reserves—and their recent advances into new areas. They review the considerable work that has been done on the resting habits and breeding-sites of different Glossina species, knowledge of which is important for effective control, and research on predators of pupae and adult flies and on the feeding activity of tsetse flies. Means of assessing populations and various factors affecting the size and nutritional status of tsetse flies are also discussed, as is the effect on the fly population of artificial changes in the habitat. Finally, a plea is made for a revision of present methods of land use and stock management, if full advantage is to be taken of achievements in fly control.Item The Root Systems of Some British Somaliland(1951) Glover, P.E.The significance of an understanding of root systems in regard to existing conditions and redemption of devastated areas in relation to the geography, soils, vegetation cover and carrying capacity is essential.Item The Root Systems of Some British Somaliland Plants-III(1951) Glover, P.E.Acacia misera Vatke is a common, large, thorny shrub in most parts of the country from the Guban to the Haud, and has an altitude range from 1,000 feet to 4,000 feet. It flourishes on sites of prolonged devastation and sometimes forms almost "pure stands".' Good examples of this can be seen a few miles to the west of Odweina, and in parts of the Haud. The plant may grow to a height of 3 or 4 metres, and have an equal crown diameter measurement. It has a very well developed shallow lateral root system. It was noted in several instances that the tap-root tapered down suddenly from a thickness of 7 or 8 cm. at ground level to 2 or 3 cm. at a depth of 30 or 40 cm. In the Guban this plant seemed to prefer stony or coarsely gravelly soil:Item Termitaria and Vegetation Patterns on the Loita Plains of Kenya(1964) Glover, P.E.; Trumpe, C.; Wateridge, L.E.D.; Department of Veterinary Services, KenyaThe Loita and contiguous plains areas of Kenya are described, with details of their geology, soils, climate and general ecology. The plains are mainly open grassland which is subjected to frequent burning and heavy grazing. The striking vegetation patterns which are characteristic of the Loita plains are shown to be associated with the regular distribution of low termite mounds. The vegetation patterns and underlying soils are described in detail and it is suggested that the patterns develop on soil zones containing varying concentrations of colloidal matter washed from the termite mounds at their centre. The shape of the pattern is influenced by topography.Item Termitaria and Vegetation Patterns on the Loita Plains of Kenya(Department of Veterinary Services, 1964) Department of Veterinary Services; Glover, P.E.; Trump, E. C.; Wateridge, L. E. D.Air photographs of parts of East Africa characteristically show extensive areas where regular patterns produced by mound-building termites are prominent. Some of the patterns form a conspicuous feature of the landscape but others are difficult to distinguish.Distinctive vegetation zones occur on the mounds and often on the surrounding ground if it is affected by rain wash from the mounds.
