Conteúdo: |
Soil fauna diversity and density are recognized as essential parameters for the functioning of
the soil system, and are in a large extent related to soil moisture and to the amount and quality of
litter covering soil surface. In turn, litterfall and litter layer are influenced by vegetation structure
and floristic, as well as by climatic characteristics of a given region. Thus, climate changes
which affect forest productivity and/or structure will also cause changes in litter dynamics, with
corresponding changes in the decomposer?s community, in decomposition processes, and in
soil engineering activities of soil biota. In Amazonia, recent evidences suggest that increased
atmospheric CO2 concentration is causing: (i) increases in trunk growth (and in the biomass) of
emergent trees, without a correspondent increase in the smaller trees; (ii) increases in the biomass
of lianas; (iii) increases in fine litter production. The quality of the litter deposited on soil surface
is likely changing correspondingly, inducing changes in soil carbon and soil biota. Direct effects
of such changes on soil fauna are still scarce but indications from recent studies are indicating
that: (i) drier environments, as illustrated by border effect within a fragmented forest, cause
higher litter production, accumulation, quality change, and related changes in the decomposer
community; (ii) drier litter layers, as found during the dry season in Amazonia, induce strong
changes in soil and litter fungi and fauna densities and activities, illustrating what may be expected
in case of prolonged droughts as those caused by the ENSO phenomenon; (iii) drier soils, as
induced by rainfall interception, support a reduced or modified activity of soil biota. Current and
planned experiments in several regions of Amazonia shall improve considerably our
understanding of the actual effect of climate change in soil biodiversity and processes mediated
by soil biota within the next few years. MenosSoil fauna diversity and density are recognized as essential parameters for the functioning of
