ABSTRACT -
Cropland expansion has been occurring over the last century, especially in South America, displacing non-crop areas mainly with soybean. Changes at a landscape level were followed by changes at a local scale, such as the adoption of insect-resistant transgenic crops. The homogenization of agroecosystem composition and agronomic practices have a great impact on arthropod predators and herbivore insects, which has not been quantified to a great extent in South America. We evaluate the effects of cover composition (1 km radii) as a landscape variable, and Bt adoption as a local variable on the quantity of the main predators and pests in soybean fields in Uruguay. Over a two-year period, we sampled 60 soybean fields with sweep net and beating sheet. We found that Bt and non-Bt soybean fields did not differ in the number of predators and stink bugs, while Bt fields were associated with less caterpillars? abundance. The proportion area of soybean negatively affected the quantity of some predators in this crop. In contrast, the landscape cover with natural grassland, commercial forest and maize positively affected some of these beneficial organisms. The number of stink bugs in soybean was highly affected by the surrounding cover composition. Arthropod responses depend on soybean's phenological period. We demonstrate the effects of the agriculturalization process on soybean predators and pests, suggesting that Bt adoption does not affect predators and each vegetation cover impacts them differentially. Different non-crop landscape cover and the abundance of predators in the field margin are positively associated with the abundance of predators in soybean fields. © 2022 Elsevier B.V. MenosABSTRACT -

Abstract:
Aims: The Rio de la Plata grasslands are one of the largest areas of temperate humid and sub-humid grasslands
of the world. A substantial fraction of these natural grasslands are preserved in Uruguay, occupying more than
60% of the country. So far, Uruguayan grasslands have been indirectly classified using only geomorphological
and edaphic criteria. An adequate description of vegetation heterogeneity is a prerequisite to study ecosystem
function and to design management and conservation strategies for this region. To this end, we present a classification of the natural grassland communities of Uruguay based on a wide and comprehensive set of phytosociological relevés. Study area: Uruguay. Methods: Three hundred eight grassland relevés were utilized for classification and ordination multivariate analyses. Agglomerative clustering based on the flexible Beta linkage
method and Sørensen distance measure were employed to identify relevé groups. Indicator species analysis was
also performed to identify diagnostic species. We used Non-metric multidimensional scaling to determine the
main floristic gradients. Results: Five communities and 14 sub-communities were identified. Two of the communities were restricted to the ?Basaltic? region of central and northern Uruguay, while the other three were
distributed through the Eastern Hills, North Eastern Sedimentary Basin and the South Central regions. Three
of the communities correspond to densely-vegetated grasslands associated with medium and deep soils. The
remaining two communities correspond to sparsely-vegetated grasslands on shallow soils. The main floristic
gradient separated sparsely-vegetated grasslands from densely-vegetated ones, and was related to soil and topographical characteristics. The second floristic gradient separated grasslands by their different geological substrates. Conclusions: In this study, we present the first attempt to conduct a vegetation classification of Uruguayan grasslands based on floristic composition. Vegetation typologies, like the one we propose, can be used
as a framework to extrapolate point information on grassland management and vulnerability.
