Species differences in substrate use and diet between sympatric galagos in two Kenyan coastal forests

Abstract: Two sympatric species of galago,Galago zanzibaricus andG. garnettii, differed significantly in diet (judged mainly by fecal analysis) and substrate use at each of two coastal forest sites in Kenya. The larger-bodiedG. garnettii tended to use branches of a bigger diameter and to be found higher in the canopy than the smallerG. zanzibaricus. The latter species spent most of its time in the thick undergrowth. The larger species ate more fruit than the smaller. There were differences between the species in the type of invertebrate prey remains found in the feces. It is suggested that the differences in habitat use were influenced by the different body sizes of the two galagos, which so enabled these closely related species to coexist.

The Influence of Undergrowth Distribution on Utilization of Space by Bank Vole Populations

Abstract: Studies were made in 1-hectare areas situated in 9 types of tree stand of the influence of clustered and random distribution of undergrowth on the spatial organization of Clethrionomys glareolus (Schreber, 1780).

Early regrowth in rehabilitated bauxite minesites as breeding habitat for birds in the jarrah forest of south-western Australia

Abstract: Summary A survey was undertaken lo assess 5 to 10-year-old rehabilitated bauxite minesite vegetation as suitable habitat for birds while breeding during spring in the jarrah (Eucalyptus marginata) and marri (E. calophylla) forest at Jarrahdale. Western Australia. The minesites had been rehabilitated and revegetated with local shrub species and a mix of local and eastern eucalypts resistant to the root rot fungus Phytophthora cinnamomi. Twenty-one species of birds used the former minesites for foraging or hunting while breeding; twelve of these were found nesting or rearing fledglings in the revegetation. Among the breeders were four understorey dwelling species which were otherwise uncommon in surrounding upland forest or (in two cases) confined in stream zone undergrowth. Total densities of all pairs or groups breeding in minesites were similar to those in nearby forest. Breeding territories often spanned areas of both minesite and forest around the edge of pits. Eleven other species were found breeding ...

Effect of Forest Covers on Physico-chemical Properties of Soils Developed on Sand Stone

Abstract: Physico-chemical properties of soils belonging to great group of Haplustali/Hapiustoli and developed from Gondwana land stone in similar physiographic and environmental conditions were studied under three forest covers Viz., miscellaneous cover, teak plantation and Eucalyptus cover in Kotma and Ghunghuti ranges of South Shahdol and North Shahdol Divisionl of M.P. respectively. Weathering processes seem to be quite active in soils under followed by Eucalyptus cover. Ratios of clay to non clay fractionl, thickness of 'A' horizon, per cent organic matter, cation exchange capacity, exchangeable Ca and Mg were more under teak cover than that of Eucalyptus . Soil pH lowered down more under Eucalyptus plantation than in teak plantation. Soluble salts were more under Eucalytus cover. Performance of Eucalyptus was better on Ghunghuti range where as teak was better on Kotma rangue Eucalyptus supports undergrowth of different tree species.
