“…Soil nitrogen affected tree photosynthesis and LAI by influencing the content and distribution of leaf nitrogen (Vose andAllen 1988, Warren et al, 2003); in turn, LAI also affected SN. The high biomass increased the amount of litter and contributed to the increase of SN content (Martins et al, 2021, Yokobe et al, 2021. High LAI significantly increased canopy interception of rainfall, significantly reduced surface runoff and soil erosion, and thus reduced surface nitrogen leaching loss (Malek 2010, Mohammed andTarboton 2016).…”

Context . Changes in landscapes due to conversion of natural vegetation into agroecosystems are causing an alarming and rapid loss of biodiversity on a global scale. Objectives . We assess how local environmental factors and landscape structure influence Squamata reptiles' abundance, alpha and beta diversities in agricultural landscapes in the Brazilian Cerrado. Methods . We sampled 20 sites using active visual search and pitfall traps to record Squamata reptiles' abundance and richness. For each sampling site, we measured seven variables of vegetation structure at local scale and calculated four landscape metrics at five spatial scales. Results . We recorded 145 individuals of 30 Squamata species being 15 lizards, 12 snakes and three amphisbaenians. Agriculture cover had a negative effect on lizards' abundance and richness. No effect was found on the abundance and richness of snakes. Species turnover was the major process responsible for Squamata reptile dissimilarity among sites. Reptile total beta diversity and species turnover were explained by variation in the number of trees at local scale. Conclusions. Our results highlight the negative effects of agriculture expansion at both species abundance and richness in lizard communities. Moreover, vegetation structure may act as an environmental filter and predict the variation in Squamata reptiles’ species turnover between sites. Our findings show that the maintenance of well-preserved patches of natural vegetation in agricultural landscapes are of utmost importance for Squamata reptiles’ conservation and should be considered in landscape conservation and management design.

“…Particularly in Brazilian Cerrado, litter dynamics may be an important determinant of community structure and composition (Villalobos-Vega et al, 2011). Soils are poor in organic matter, phosphates, nitrogen, and micronutrients, but litter of this same vegetation may have considerable amounts of these same nutrients (Martins et al, 2021). In these poor soils, litter decomposition may provide major nutrients for vegetation development.…”

The biodiversity in agricultural landscapes depends on land-use types, natural elements, and farming intensity. The Brazilian Cerrado is a biodiversity hotspot, however, the native vegetation loss rates have increased in the last years, leading several plant species to extinction risk. Here, we analyze the effects of local (soil fertility and litter amount) and landscape variables (patch shape, habitat amount, compositional heterogeneity, matrix dominance and connectivity) on alpha species richness and diversity, and basal area of different Cerrado vegetation types (savanna, forested savanna, and forest) using linear models and Akaike information criterion. We calculated landscape metrics at different spatial scales for 49 sampling sites in intensive farming landscapes. Woody plant diversity and richness were positively related to soil fertility and landscape compositional heterogeneity at 1500 m spatial scale. Plant richness was negatively related to the patch shape of remnants at 1000 m spatial scale. The effects of litter amount to explain the basal area varied between vegetation types.We found a positive effect in savanna and forested savanna and a negative effect in forest areas. Our findings suggest that the increase of monocultures lead to a decline on plant diversity in the studied landscapes. Also, local variables and the diversity of vegetation types need to be considered to design restoration actions in Cerrado.Sustainable intensification and biodiversity-friendly production systems may be alternatives to increase compositional heterogeneity, thus favoring plant diversity in Cerrado farming landscapes.
