Abstract
The Mount Elgon region of Uganda has coffee farmlands distributed along the slopes of the mountain, in a mosaic of differing
crop combinations, and semi-natural vegetation. Thus, there are parcels of varying microclimate that create disparities in
occurrence of key insect functional groups. The study quantified the occurrence of Carabidae in 72 coffee farmlands categorized
by altitude: low (1400–1499 m.a.s.l), mid (1500–1679 m.a.s.l), and high (1680–2100 m.a.s.l); and farming system: coffee
monocrop, coffee+annual crops, coffee+banana, and coffee+banana+shade trees. The results revealed highly significant effects
of altitude, farming systems, and the interaction of the two on occurrence of three Carabidae genera (Anisodactylus, Chlaenius,
and Harpalus.). The abundance of Harpalus spp. was higher at lower altitudes in coffee monocropped farming systems;
Anisodactylus spp. were more abundant at higher altitudes in coffee+annual crop systems; and Chlaenius spp. were highest in
the coffee+banana+shade tree system at mid altitudes. The belowground microclimate parameters of soil moisture, pH, EC; and
the aboveground diversity of semi-natural vegetation explained some of the differences in occurrence of the different Carabidae
genera. This distinctiveness in preference of different genera in the same family hinders collective recommendations but looks to
a more pragmatic strategy in nurturing diversity on a holistic scale.
