Land-use intensification along with a gradient of forest fragmentation is known to negatively
affect diversity of soil collembolan communities at the local level. This assumption was
supported by the results of the former EU BIOASSESS project, where the effects derived
from changes of landscape composition and structure along a land-use intensification gradient
(within 8 European countries) were evaluated following a traditional ?taxonomical? approach.
However, the biodiversity assessment based on this approach did not show a common
pattern between countries along the forest fragmentation gradient. Eco-morphological and
life-history traits such as dispersal behaviour, habitat width, life forms and reproductive
strategies could draw a more informative picture of diversity changes originated by the
dynamics of the landscape. For instance, traits that allow species to survive in dynamic
landscapes (fast-dispersal species), such as heterogeneous agro-forest mosaics, are likely
to be different from those allowing species to persist locally, and may be related to the
colonising ability of the species. On the other hand, slow-dispersal collembolans able to
survive in highly disturbed monotonous agricultural landscapes (tolerant species), are
expected to have a different trait composition in relation to the sensitive slow-dispersal species
occurring in the homogenous forest landscapes. In this way the response of species diversity
patterns to the forest fragmentation gradient could be more clearly explained by the underlying
collembolan trait structure emerging in each landscape type. So far there are only few attempts
to assess the impact of disturbance on collembolan communities using traits, probably due
to a lack of data on several species. In this study, based on an extensive collembolan trait
database, we revisited the BIOASSESS datasets and focused the analysis on the response
of collembolan trait patterns to the forest fragmentation gradient at each one of the 8 studied
European sites. The aim is to examine the extent to which life-history and eco-morphological
traits are able to depict a common response pattern of collembolan communities among
countries as an effect of the changes of landscape composition and structure. At each country
we have analysed the total functional diversity (trait dissimilarity) on each landscape window
along the fragmentation gradient and also the functional diversity of three major groups of
species, i.e., those species decreasing in abundance, species increasing in abundance,
and species not significantly changing in abundance along the gradient. A common response
pattern to fragmentation among the different countries could be found not only when looking
at the different landscape windows, but especially when analysing each one of the three
groups of species. Among the different groups of traits considered in the analysis, those
more related to dispersal behaviour were the ones contributing most for observed similar
response pattern among countries. This analysis revealed that species traits could be a
good alternative tool to the traditional taxonomic approach when trying to define common
response trends of communities to disturbance regimes MenosLand-use intensification along with a gradient of forest fragmentation is known to negatively
