AVALIA\uc7\uc3O DO POTENCIAL DE APROVEITAMENTO ENERG\uc9TICO DOS RES\ucdDUOS DE MADEIRA E DERIVADOS GERADOS EM F\uc1BRICAS DO POLO MOVELEIRO DE UB\uc1 - MG

The present study evaluated the energy reuse potential of the wooden residues and its derivatives generated in the industrial furniture stave of Ub\ue1, Minas Gerais state, Brazil. Reconstituted panels of MDF (medium density fiberboard), particleboards and plywood were characterized and classified. A research carried out in 11 furniture plants verified that the wooden residues represent more than 90 % of the solid wastes. Besides of this the large amount generated, no integrated action was identified to the management of the residues, neglecting its environmental and sanitary risks, as well as its energy use potential. However, the moisture and calorific power of the residues demonstrated a high potential energy use through the briquette production. The gases generated by combustion of the residues did not presented toxic substances above the limits of Brazilian legislation. However, the leached ashes of the residues of agglomerated BP (low pressure) and FF (finish foil) presented high chromium concentrations, classifying them as Class I (dangerous), according to ABNT/NBR 10004/2004.O presente estudo avaliou o potencial de reaproveitamento energ\ue9tico dos res\uedduos de madeira e seus derivados gerados no Polo Moveleiro de Ub\ue1, MG.

Crescimento e produtividade do pinhão-manso em função do espaçamento e irrigação Growth and productivity of physic nut as a function of plant spacing and irrigation

Objetivou-se, com este trabalho, avaliar o efeito do espaçamento e da complementação hídrica no crescimento e produtividade do pinhão-manso. O experimento foi conduzido na área experimental do Instituto Federal Goiano, campus Rio Verde,GO, no período de 12/09/2009 a 30/04/2011, no delineamento de blocos casualizados com três repetições, os fatores foram sete espaçamentos e duas condições hídricas, cada parcela constituída de 16 plantas, sendo as quatro plantas centrais a área útil. Aos 60 dias após o transplantio das mudas foram feitas, bimensalmente, as avaliações dos parâmetros altura de planta, número de ramificações, área foliar e produtividade. O fator espaçamento não apresentou diferença significativa para os parâmetros altura, ramificação e produtividade e a complementação hídrica teve efeito significativo para altura aos 240 dias após transplantio. A produção de sementes em sequeiro foi maior no espaçamento 3 x 3 e com complementação hídrica no espaçamento 4 x 4.<br>The objective of this study was to evaluate the effect of plant spacing and water supplementation on growth and productivity of physic nut (Jatropha). This research was carried out at the experimental area of the Instituto Federal Goiano - Rio Verde during the period 12/09/2009 to 30/04/2011, in a randomized block design with three replications. The factors consisted of seven plant spacings and two water conditions, each plot consisted of 16 plants, and four central plants were considered for data collection. At 60 days after transplanting of seedlings, fortnightly the evaluation of the parameters plant height, number of branches, leaf area and productivity was carried out. The plant spacing showed no significant difference for height, branching and productivity, while the water supplementation had significant effect on height at 240 days after transplanting. Seed production under rainfed conditions was higher in 3 x 3 m spacing and with complementary water in 4 x 4 m spacing

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
