As deforestation of neotropical primary forest continues the proportion of secondary forests of
total forest area increases. Therefor, the interest in secondary forest fragments for management
and conservation issues grows. The project SOLOBIOMA evaluate the ecosystematic quality of
secondary forests in the coastal submontane forest of Paraná state, southern Brazil.
The objective of this study is a diversity survey of litter-dwelling beetle assemblages as part of
the soil invertebrate community which are recognised as important components of biodiversity
and an evaluation of the recovery process during forest regeneration . Spatial changes in species
richness, abundance and assemblage structure of e.g. carabids and curculionids were studied
using three replicate chronosequences. Three regeneration stages of secondary forest ranging
in age from 4 to 55 years after anthropogenic disturbance - here totally deforestation to pasture
- as well as old-growth forest (>100 years, only some logging activities known) were included,
making a total of 21 sites. Each succession stage was selected on two soil types (cambisol and
gleysol) to estimate the influence of soil associated environmental conditions on the distribution
pattern of leaf-litter beetles. Between July and June 2003 twenty 1m2 leaf-litter samples were
taken at each study site and were treated using the Winkler technique.
A total of 3742 beetles were extracted belonging to 37 families. 80 % of all individuals were
staphylinids (22% plus 30% Pselaphinae), carabids (10.5%), scydmaenids (9%) and curculionids
(8.5%). Carabids and curculionids were determined to 48 morphospecies.
Uni- and mulivariate statistical analysis revealed high increase of species richness and significant
changes in species composition towards old-growth forest conditions during secondary
succession on cambisol. But there were no significant differences in species richness and species
composition between the oldest secondary forest stage and old-growth forest. On gleysol a
weaker increase of species richness with increasing forest age and clearly lower species richness
than in the corresponding stages on cambisol were observed. Species composition on gleysol
changed in-consistently during forest regeneration.
These first results suggest a fast recovery of the leaf-litter beetle community during natural forest
regeneration at least on non-temporarily flooded forest areas. MenosAs deforestation of neotropical primary forest continues the proportion of secondary forests of
