Human-induced disturbance related to land-use intensification, such as agricultural and
silvicultural practices, has lead to a depletion of biodiversity in agro-forestry systems. Nevertheless,
regarding the Mediterranean region, some activities like traditional grazing have favoured habitat
heterogeneity, increasing species diversity. This extensive management, according to the
Intermediate Disturbance Hypothesis, can promote biodiversity by providing a dynamic mosaic
pattern of closed and open habitats. Ground-beetles are a widely distributed group of insects
that usually dominate agro-ecosystem biocoenosis. Considering their sensitiveness to landscape
structure and land-use changes, ground-beetles were used to monitor biodiversity along a
gradient of land-use intensification, from old-growth cork-oak woodland to an agriculture
monoculture, in a typical Mediterranean landscape (in 2001 and 2002). The work also included
a land-use unit of Eucalyptus plantation in the second year. During this study, a total of 11 294
individuals of ground-beetles were sampled, grouped in 101 different species (2001: N=4776,
S=80; 2002: N=6518, S=77). Agricultural unit recorded the highest abundance and diversity
levels, while the eucalyptus unit recorded the lowest values. Concerning ground-beetles? diversity
patterns, a Canonical Correspondence Analysis clearly differentiated open areas from closed
woodlands. Mosaic landscapes with major cork-oak cover revealed a higher abundance and
number of species that are more sensitive to human disturbance, i.e. woodland specialists.
These results showed that despite the higher diversity found in open areas, habitat heterogeneity
in agro-ecosystems is crucial for species turnover between those and woodland field boundaries
and therefore for ground-beetle conservation in typical Mediterranean landscapes MenosHuman-induced disturbance related to land-use intensification, such as agricultural and
