The effect of change in land use on soil macrofauna communities in Mabira Forest, Uganda

摘要: Summary The composition, density, biomass and diversity of soil-macrofauna communities were assessed in eight land-use categories the Mabira Forest Reserve, towards end rainy season. Some soil characteristics also measured, seven sites. Sixteen orders recorded The cleared uncultivated site had highest density (1247 m-2) (9 per sample), whilst lowest occurred one-year cultivation (200 m -2) twenty-year (5 1 sample) respectively. Natural forest (9-8 g four-year (31 m-2). Following continuous for a year, faunal tended to fall along with organic matter, total nitrogen, available phosphorus exchangeable potassium soils. In general, clearance have deleterious effects on soils macrofauna its chemical physical properties. Resume On evalue la densite, biomasse et diversite des communautes de macrofaune du sol dans huit differentes terrain, reserve forestiere Mabira, vers fin saison pluies. En sept endroits, aussi mesure certaines caracteristiques sol. On releve seize ordres aux endroits. Le degage non cultiveetait celui qui abritait les plus fortes densites (1247/m2) ordres/echantillon) tandis que basses densite s'observaient respectivement un cultive depuis an (220/m2) vingt ans (51 ordres/echantillon). La foret naturelle abrite grande g/m2), le quatre ans, faible (3-1 g/m2). suivant une culture continue pendant an, voit animale tend baisser en meme temps matiere organique, l'azote total, phosphore disponible libre contenus sol. En degagement forets ont effets destructeurs sur ses proprietes chimiques physiques.
