The preservation of tropical forests is increasingly at risk, including forests located within human-modified landscapes that retain high conservation value. People modify and interact with these landscapes through a wide range of uses. However, our knowledge of how different forest uses affect biodiversity is limited. Here, we analyse the responses of different taxa to four distinct categories of forest management, namely oldgrowth forest, Brazil nut extraction areas, reduced impact logging areas, and eucalyptus plantations. Within six independent replicates of each category, we sampled three taxa (fruit-feeding butterflies, dung beetles, and trees) in eastern Amazonia. Forests under moderate use (Brazil nut extraction and reduced-impact logging) had similar, albeit slightly lower, diversity levels relative to old-growth forests, while communities in plantations were significantly less diverse. Only 4%, 20%, and 17%, of the sampled butterfly, dung beetle, and tree species, respectively, were restricted to old-growth forests. This study provides further empirical evidence of the importance of old-growth forest conservation in the context of human-modified landscapes. It also suggests that landscape matrices integrating forest uses at varying intensities are well positioned to reconcile biodiversity conservation with the production of goods that support local livelihoods. |

Performance of soil management systems was initiated in 1995 in a field experiment in Dourados, MS,Brazil, with the following systems: CS ? conventional tillage; NTS ? no-tillage; ICLS ? integrated crop-livestock with soybean (Glycine max (L.) Merr.) and pasture under no-till, rotating every two years, and PP? permanent pasture. Pastures (Brachiaria decumbens) were grazed by heifers with stocking rate adjustedto constant supply of forage. The hypothesis was that rotation of crops and pastures would be moreefficient and present beneficial effects to the environment. More complex and diversified productionsystems may exhibit synergism between components to result in better soil physical structure, greaterefficiency in use of nutrients by plants, greater accumulation of labile fractions of soil organic matter,greater diversity and biological activity in soil, and lower occurrence of nematodes and weeds. Better soilconditions in ICLS allowed greater resilience; over the years of assessment soybean and pasture yieldswere less affected by drought and frost. The ICLS was very efficient, accumulating soil C and reducingemissions of greenhouse gases. Soil quality was improved in integrated systems with larger numberof components and greater interaction between these components (ICLS) compared to simple systems.Based on soil attributes, we affirmed in this long-term study that the ICLS system is agronomically andenvironmentally efficient and sustainable. |
