Soil and climatic conditions allied to advanced forestry technologies have enabled the development of planted forests in some regions of Brazil with some of the highest productivity rates in the world. However, the intense use of agricultural inputs and mechanization of production and wood transportation imply significant environmental impacts, such as the emission of carbon and nitrogen compounds. The purpose of this paper is to compare a model of an Integrated Crop-Livestock-Forestry System with more conventional eucalyptus forestry using a Cleaner Production approach to demonstrate the economic and environmental advantages of such a system. This is based on an environmental, energy, and economic analysis integrating Life Cycle Assessment and Cleaner Production approaches. Life Cycle Inventories consist of primary data obtained from the states of Bahia, Espírito Santo and Minas Gerais in Brazil, in partnership with Forestry Producers and a Forestry Company, which is the largest producer of hardwood pulp in the world. The inventories of conventional short-cycle eucalyptus production systems to supply the Forestry Company were quantified from seedling preparation to harvesting operations. The following production systems were evaluated: Reference system – Planting + Replanting (S1); Planting + Regrowth (S2), and Crop-Livestock-Forestry (S3). The adoption of CP measures in S3 reduced the use of inputs by 35% and increased gross revenue compared to S1. The processes that most contributed to the impact categories analyzed were soil preparation, emissions of inputs used in the field, and mechanized harvesting. However, biogenic carbon sequestration included −783 kg CO 2 eq/m3 of wood for S1. The S2 system had lower impacts compared to S1. Integrated Crop-Livestock-Forestry System - S3 showed a better environmental performance for most of the impact categories analyzed and presented a better financial return compared with S1 and S2. The implementation of the CP measures in S3 provides an immediate payback. Based on the conditions of this study, the CP strategy for silviculture is an economically viable option to increase the net CO 2 sequestration of forest production. This research intends to promote the study of eucalyptus forest production under tropical conditions, using the combined use of LCA and CP approach presented in this study from primary data. The CP and LCA integration provided methodological advances and more detailed information on the environmental performance of short-cycle eucalyptus production by identifying operational practices for the analyzed systems yielding environmental and financial gains. CP proved to be effective in providing information for decision-making at the process level without losing the broader view of the environmental performance of the analyzed product systems.

Individual diet specialization is commonly found in generalist species but has been little studied in folivore mammals. Empirical evidence shows that the diversity of food resources in the habitat affects the degree of this specialization, by influencing among-individual diet variation (diet similarity) and individual niche breadth (diet diversity). We aim to evaluate the diet composition and selection of maned sloths (Bradypus torquatus, Illiger 1811) in two distinct ecological contexts; test whether the diet similarity between individuals and populations is explained by changes in the local floristic compositions and/or by a differentiated selection of tree species, and evaluate the effect of the local tree diversity on the diet diversity and similarity across individuals. We monitored 13 individuals in northern Bahia and Rio de Janeiro and accessed the tree species diversity and availability within each home range. We identified 67 tree species consumed, most of which were consumed in higher proportion than their availability in the home ranges, indicating high selectivity by the individuals. Diet similarity decreased with greater differences in the local floristic composition and higher tree diversity, but was also influenced by individual selection. Together, our results evidence that the maned sloth is specialist and selective at the individual level, and the lower tree diversity reduces individual diet specialization, revealing tree species that are commonly preferred at the population level under such condition. Our results can be directly applied to feeding protocols of captive populations, and ecological restoration initiatives focusing on the conservation of this threatened species. [ABSTRACT FROM AUTHOR]
