“…For example no detectable change in species richness has been documented for the Kammanassie Mts in South Africa (NEL et al 1980), for the Cape Mts in South Africa (BOND et al 1980), for montane habitats in Malawi (HAPPOLD & HAPPOLD 1992), for the Philippines (HEANEY et al 1989) and in this study. An increase of species richness with increasing altitude was evident for the Bale Mts in Ethiopia (YALDEN 1988, SILLERO-ZUBIRI et al 1995, the western slopes of the Andes (PEARSON & RALPH 1978) and in Texas (OWEN 1990).…”

“…Thus rodent species richness along altitudinal gradients is a function of habitat complexity and heterogeneity and not exclusively of elevation (see also BOND et al 1980, HAPPOLD & HAPPOLD 1992. PEARSON & RALPH (1978) found an increase of species richness with increasing altitude in birds and small mammals on the western side of the Andes.…”

Small mammals were surveyed along a transect in Mt Elgon National Park, Uganda, at altitudes from 2900 to 4300 m a.s.l., with the main focus in the Afroalpine grasslands above 3500 m a.s.l. In this study, 13 species belonging to the Muridae were recorded, but only one species Lophuromys flavopunctatus Thomas 1888, occurred in all habitats. The highest species and individual numbers were found in richly structured vegetation in the Afro-alpine zone. Twenty-four species of Muridae and one Gliridae have been recorded from the Mt Elgon NP, Uganda (> 2000 m a.s.l.) so far, two more have been found on the Kenyan side and are likely to occur in Uganda. A total of 34 species of Muridae have been recorded on the whole range of Mt Elgon, two being endemic to the Afro-alpine zone, one listed as vulnerable and one as rare by the IUCN (LIDICKER 1985).The present distribution patterns and composition of the montane rodent communities are a result of different evolutionary histories mainly brought about by past changes in climate and vegetation. A number of montane rodents in Africa are relict forms, which declined due to habitat changes and competition from invading "modern" species.

Isto sugere que diferentes sistemas devem comportar-se de forma distinta e evidencia a necessidade de uma teoria geral que responda por estas di ferenças.…”

ABSTRACT. STRUCTllRAL IIETEROGENErrV AI"D DIVERsrrv OI' SMALL MAMMAL~IN A SECONDARY FOREsr FRAGMENTOF MINAS GERAIS. BRASIL. The aim is lo delermine lhe rclalionship helween lhe diversily of small mammals and the slructural helerogeneity and/or seeondary suceessional slages in an Atlantic foresl fragment aI Viçosa (Minas Gerais). We used Sherman and hook live traps lo sample this fauna, monthly from may 1992 to april 1993 in lhree arcas: an ahandoned planlation of Melinis mil1llliJInra (campo) and lwo distincl forest arcas (capoeira and mala). The slruelural hclerogeneily was delermined as a funclion of lhe presence of dead lrees. pioneer species. epiphytes. lhe distances helween trees. lhe lree heighl and bas.11 area measured hy a modified quadrant sample melhod (ConAM & CURTtS 1945). It was sampled a lotai of 340 individuais bclonging to 17 species. The homogeneous plantalions had the highesl diversily (H" = 1.67). Among lhe lWO foresls stands lhe lcss helerogeneous capoeira had similar diversity (H" = 1.19) lhan lhe more helerogeneous stand. lhe mala (H' = 1.13). The unexpected higher diversily and species richness in lhe more homogeneous habitat may he explained hy some hidden faclor which decrease lhe compclilion for resources in lhis communily. KEY WORDS. Con1lnunily slrueture. habilal helerogeneily. small man1lnal divcrsity A grande diversidade de espécies observada nos Trópicos Úmidos pode ser correlacionada com a relativa estabilidade climática (KARR & ROTH 1971) e com a alta produtividade primária (PIANKA 1967). Entretanto, o padrão de biodiversidade faunística vem sendo alterado pelo crescente desenvolvimento econômico das regiões tropicais (WILSON 1988) que tem como resultado a fragmentação dos sistemas tlorestais dessas regiões.A Floresta Atlântica Brasileira é um dos ecossistemas em que as conseqüên-cias desse processo de colonização podem ser melhor visualizadas. Acredita-se que menos de I % da Mata Atlântica permanece em sua forma não-perturhada

“…Numbers of O tom ys may have been inaccurately estimated in several southern African field studies (inter alia Toes, 1972;Bond et al, 1980;Perrin, 1980). A common denominator in these studies was the use of baits apparently unsuited to catching O tom ys.…”

“…A common denominator in these studies was the use of baits apparently unsuited to catching O tom ys. Perrin (1980) used peanut butter to sample O. irroratus, while baits consisting of peanut butter, rolled oats, animal fat and/or candle w ax were used for O tom ys complexes comprising O. irroratus, O. laminatus and O. saundersae (Toes, 1972;Bond et al, 1980). Davis (1973) baited with rolled oats and currants, however, and following three days o f prebaiting captured 95% of O tom ys (O. angoniensis and O. irroratus) in three-day trapping periods.…”
