“…Conversely, species diversity was higher in reduced-tillage barley than in conventionaltillage barley. In alfalfa, ground beetles were more abundant in reduced tillage than in conventional tillage, yet there were no differences in species diversity (Barney and Pass 1986). This is similar to our findings with ground beetle assemblages, except that here both no-tillage and minimum-tillage regimes are conservation practices and species diversity was higher in minimum tillage wheat in 1995, but not in 1996.…”

“…In this study, 9 species (12.3%) of the 73 species captured accounted for 61.7% of all ground beetles captured. Other studies also have found that a few species dominate the ground beetle fauna in agroecosystems (Kirk 1971, Barney and Pass 1986, Laub and Luna 1992, Tonhasca 1993, Carcamo 1995. The number of ground beetles captured in 1995 more than doubled the number captured in 1996.…”

“…It is known that some species of ground beetles will aggregate in areas with high population densities of cereal aphids (Bryan and W ratten (1984). Other studies have shown mixed preferences by ground beetles in agricultural crops when reduced tillage was employed (Dritschilo and Wanner 1980, Barney and Pass 1986, Gircamo 1995. Carcamo (1995) found a higher abundance of ground beetles in conventional-tillage barley than in reduced-tillage barley that was attributable to an unusually high number of 1 species.…”

“…The effects of conventional and conservation tillage practices on species diversity and relative abundances of ground beetle species have been studied widely (Tyler and Ellis 1979, Dritschilo and Wanner 1980, Barney and Pass 1986, Weiss et al 1990, Laub and Luna 1992, Tonhasca 1993, Carcamo 1995. Although ground beetle diversity sometimes increases with decreased tillage (Stinner and House 1990), other indications are that diversity and abundance are not changed (Barney and Pass 1986).…”

“…Although ground beetle diversity sometimes increases with decreased tillage (Stinner and House 1990), other indications are that diversity and abundance are not changed (Barney and Pass 1986). In the northern Great Plains, ground beetle diversity and abundance were altered more by some crop rotations than by tillage practices (Weiss et al 1990).…”

Conservation tillage (CT) is widely considered to be a practice aimed at preserving several ecosystem functions. In the literature, however, there seems to be no clear pattern with regard to its benefits on species diversity and species composition. In Northern Italy, we compared species composition and diversity of both vascular plants and Carabids under two contrasting tillage systems, i.e., CT and conventional tillage, respectively. We hypothesized a significant positive impact of CT on both species diversity and composition. We also considered the potential influence of crop type. The tillage systems were studied under open field conditions with three types of annual crops (i.e., maize, soybean, and winter cereals), using a split-plot design on pairs of adjacent fields. Linear mixed models were applied to test tillage system, crop, and interaction effects on diversity indices. Plant and Carabids communities were analyzed by multivariate methods (CCA). On the whole, 136 plant and 51 carabid taxa were recorded. The two tillage systems studied did not differ in floristic or carabid diversity. Species composition, by contrast, proved to be characteristic for each combination of tillage system and crop type. In particular, CT fields were characterized by nutrient demanding weeds and the associated Carabids. The differences were especially pronounced in fields with winter cereals. The same was true for the flora and Carabids along the field boundaries. For studying the effects of CT practices on the sustainability of agro-ecosystems, therefore, the focus should be on species composition rather than on diversity measures.
