“…The variation in responses among the species groups to changes in forest structure and canopy species, and the different sets of indicators identified for them, suggest that no one group can act as a surrogate for biodiversity of all other groups. Other studies have come to similar con-clusions (Prendergast et al 1993;Lawton et al 1998;Jonsson and Jonsell 1999;Vessby et al 2002;Oertli et al 2005;Simila¨ et al 2006).…”

Identification of valid indicators of biodiversity is a critical need for sustainable forest management. We developed compositional, structural and functional indicators of biodiversity for five taxonomic groups-bryophytes, vascular plants, spiders, hoverflies and birds-using data from 44 Sitka spruce (Picea sitchensis) and ash (Fraxinus excelsior) plantation forests in Ireland. The best structural biodiversity indicator was stand stage, defined using a multivariate classification of forest structure variables. However, biodi-versity trends over the forest cycle and between tree species differ among the taxonomic groups studied. Canopy cover was the main structural indicator and affected other struc-tural variables such as cover of lower vegetation layers. Other structural indicators included deadwood and distances to forest edge and to broadleaved woodland. Functional indicators included stand age, site environmental characteristics and management prac-tices. Compositional indicators were limited to more easily identifiable plant and bird species. Our results suggest that the biodiversity of any one of the species groups we surveyed cannot act as a surrogate for all of the other species groups. However, certain subgroups, such as forest bryophytes and saproxylic hoverflies, may be able to act as surrogates for each other. The indicators we have identified should be used together to identify stands of potentially high biodiversity or to evaluate the biodiversity effects of silvicultural management practices. They are readily assessed by non-specialists, ecolog-ically meaningful and applicable over a broad area with similar climate conditions and silvicultural systems. The approach we have used to develop biodiversity indicators, including stand structural types, is widely relevant and can enhance sustainable forest management of plantations.

“…Such sampling scheme may be regarded insufficient (Lawton et al, 1998;Steinbauer et al, 2012), a problem compounded by the different levels of detectability of each species (Boulinier et al, 1998), given that the surveys were relatively fast. However, the overall conclusion would not be affected by a longer sampling on each location.…”

ABSTRACT. Diversity analysis by partition is an approach employed in order to understand how communities spatially structure themselves and the factors that operate in the generation and maintenance of distribution patterns. We examined the spatial structure of species diversity of four taxonomic groups, with diff erent dispersal abilities, in 16 forest fragments in the southern region of the state of Minas Gerais, Brazil. Specifi cally, we tested: i) if the similarity in species composition would be negatively related to geographical distance between the 16 fragments; and ii) if the beta diversity of the diff erent groups could be negatively related to their dispersal abilities. Alpha diversity and the compositional similarity between localities were both low. Beta diversity was not correlated with distance for any of the groups. Primates, followed by birds, showed a higher tendency of forming similarity groupings, although in a manner that was independent from distance between fragments, as well as showed the lowest beta diversity relative values. Spermatophytes and amphibians did not defi ne groupings and presented the highest values of beta diversity. We interpreted such results as indications that the groups with higher dispersal ability (primates and birds) tend to reach, on average, farther localities and, therefore, to defi ne more similar groupings (low beta diversity). The groups with lower dispersal ability (spermatophytes and amphibians) showed the opposite tendency. Although most of the species were restricted to few localities, contributing to the low similarity, beta and gamma diversity values showed the extent which the localities are, respectively, diff erent and complementary to each other in terms of species composition. Such features reinforce and justify future conservation initiatives, both in local and regional levels.KEYWORDS.

Tanto a diversidade alfa quanto a similaridade composicional entre as localidades foram baixas. A diversidade beta não esteve correlacionada com a distância para nenhum dos grupos.

“…High N0 indicates a large number of species and high N2 a large number of species evenly distributed. Strong relations between N0 and N2 and environmental conditions were demonstrated at various spatial scales [34] and in a broad range of ecosystems such as tropical forest [35], marine ecosystems [36] and flood or fire prone ecosystems [28,37,38]. N0 and N2 were calculated for each treatments and time step.…”
