title: Forest Restoration in the State of Rio De Janeiro: Adherence to Legislation

description: ABSTRACT This study evaluated forest restoration projects filed at the state environmental agency of Rio de Janeiro (Inea), regarding the requirements contained in the Resolution Nº 36/2011. Legal, technical, environmental and ecological parameters of 65 restoration projects in the design and implementation phases were analyzed. Only 29% of the projects met the requirements of Resolution Nº 36/2011. The low compliance with the requirements of the resolution evidences the lack of knowledge of the current regulations in the state of Rio de Janeiro by the technical users of the system. This condition implies a longer time of environmental licensing. Recently, Inea has revoked Res. Nº 36/2011 through Res. Nº 143/2017, which, in addition to simplifying the presentation of restoration projects, gave rise to the State System for Monitoring and Evaluation of Forest Restoration – SEMAR.

title: Leaf-litter Entomofauna as a Parameter to Evaluate Areas Under Ecological Restoration

description: ABSTRACT The aim of this study was to characterize the leaf-litter entomofauna in degraded areas under restoration process with different restoration techniques, using the native forest as a reference and ecological indexes as parameters to select bioindicator groups. The study was conducted at “Serra do Itajaí” National Park (PNSI). The survey was conducted from winter/2014 to autumn/2016. The characterization of sampled communities was performed using identification, order, families and faunal indexes such as frequency, constancy and dominance. Overall, 11,241 insects from 57 taxonomic groups were collected in pitfall traps. The native forest showed the greatest richness observed. Groups classified as frequent, constant and dominant in all environments were the Formicidae family and Diptera Order. Significant differences were observed in the frequencies of Ptiliidae, Staphylinidae and Cicadellidae families and also Diptera Order. Coleoptera Ptiliidae, Staphylinidae families and Scolytinae subfamily showed potential as bioindicators of environmental quality at PNSI.

title: Comparison of Forest Fire Profiles in Londrina, Brazil and Pisa, Italy

description: ABSTRACT The main aim of this study was to compare the historical profile of forest fires and to elaborate a risk zoning map for the regions of Londrina, Brazil, and Pisa, Italy in the period from 2005 to 2014. The records of fire occurrences were correlated with days of rain and temperature in the study areas. The results showed that 1,435 and 629 fires were recorded in the analyzed period, affecting areas of 3,220.4 and 1,550.8 ha in the regions of Londrina and Pisa, respectively. Data were then spaced in a risk zoning map. Fire occurrences and precipitation presented inverse correlation of 0.76 and 0.81 for Londrina and Pisa, respectively. Temperature showed direct correlation of 0.82 with fire occurrences for Pisa, and inverse correlation of 0.56 for Londrina. The analyzed data may serve as subside for planning fire prevention and combat activities.

title: Caatinga Tree Wood Anatomy: Perspectives on Use and Conservation

description: ABSTRACT This work describes the anatomical analysis of the wood of four Caatinga tree species in order to determine the anatomical characteristics necessary for species segregation in functional groups, to relate them to the regional environmental conditions, as well as to infer about their management and conservation. Qualitatively, the species showed peculiar adaptations to xeric environments such as high frequency of low caliber vessels or parenchyma cells. Quantitatively, the four taxa were divided into three functional groups related to the precipitation and temperature of the Caatinga. The relationships between anatomy and the environment have shown their vulnerability to climatic variations, and have warned of the damage that can be generated by anthropogenic action. It is advisable to use the energy of the species or for use in civil construction, with the exception of Tabebuia aurea, which is appropriate for carpentry. It was verified that the anatomy of the wood has potential as a subsidy for the use, management and conservation of the studied species.

title: Litterfall and Litter Decomposition in Pinus and Native Forests

description: ABSTRACT Litter production and decomposition makes it possible to supply a good part of the nutrient demand of forest stands. Although several studies on this subject have been carried out in Pinus stands in different regions of Brazil, there are no records of studies carried out in the Northeast region, or in particular in the state of Bahia. Therefore, the objective of this work was to evaluate the litter production (litterfall) and decomposition in Pinus stands in the southwest region of Bahia, using an area of native forest as reference. Litterfall was evaluated during twelve months with the use of suspended collectors. Litter accumulation was quantified by means of three collections. The values obtained from litterfall were similar among Pinus stands. However, these values were lower than those found in the reference forest and in stands of the same genus in other regions of Brazil. Litter decomposition is relatively slow in Pinus sp. stands. The temporal variation of the litter supply is not very sensitive to the climate variations.

title: Fruits, Seeds and Oil of Brazil Nuts Produced in Mato Grosso State

description: ABSTRACT Bertholletia excelsa (Brazil nut) is the only representative of the Bertholletia genus, but presents great phenotypic variability. The objective of this study was to characterize the fruits, seeds and crude oil of Brazil nuts from the state of Mato Grosso, Brazil. Fruit and seeds from adult trees were collected at the municipalities of Alta Floresta, Cotriguaçu, Itaúba and Juína. Physical characteristics, yield and composition of the seeds, as well as crude oil characteristics were evaluated. The fruits produced in Itaúba were the smallest and had the lowest number of seeds, while those from Juína presented larger size and mass. The nuts produced in Itaúba had the lowest mean unit mass and ten-seed mass values. The seeds produced in Juína presented higher lipid content and lower ash content. The selenium content of the nuts was higher in Cotriguaçu. There were no significant differences in fruit peel thickness, yield and protein content of the nuts or characteristics of the crude oil.

title: Edaphic Macrofauna as Indicator of Edge Effect in Semi-deciduous Forest Fragments

description: ABSTRACT The aim of this study was to evaluate the edge effect using the macrofauna community of the soil as indicator in three fragments of Semi-deciduous Seasonal Forest in the city of Vitória da Conquista, Bahia, Brazil. Three sampling ranges denominated edge, transition and interior were delimited in each fragment. The macrofauna community was sampled at two seasons of the year (dry and wet). Monoliths were collected from soil at 10 cm depth in each range. The density and richness of the fauna, as well as the Shannon diversity index and the Pielou equitability index, were calculated. It was observed that the edge effect is expressed from the presence/absence of orders of individuals in the different fragment ranges, with no interference in the density, average wealth or number of individuals in each group. The edaphic community presents higher density and average richness in the dry period within the transition and interior range of the fragments.

title: Natural Resistance of Seven Amazon Woods to Xylophagous Termite Nasutitermes octopilis (Banks)

description: ABSTRACT Some Amazonian woods are considered highly resistant to the attack of microorganisms; however, which ones present the highest resistance is unknown. This study aimed to evaluate the natural resistance of seven woods to xylophagous termite Nasutitermes octopilis through a no-choice feeding assay. The following wood species were assessed: Dinizia excelsa, Manilkara huberi, Dipteryx odorata , Bagassa guianensis, Astronium lecointei, Caryocar villosum, and Hymenolobium petraeum (Ducke). To this end, five timber samples from the middle heart at breast height of each plant with dimensions of 2.54 × 2.54 × 0.64 cm (longitudinal × radial × tangential) were collected from sawmills in the municipality of Altamira, Pará state, Brazil, submitted to termite action under laboratory conditions, and had their mass loss and wear assessed, with five replicates. A. lecointei showed the lowest resistance, whereas C. villosum and D. odorata presented the highest resistance.

title: Sampling Alternatives for Eucalyptus Trees in Integrated Crop-Livestock-Forest System

description: ABSTRACT The aim of this paper was to compare methods and sampling procedures applied to eucalyptus grown under different spatial arrangements in an integrated crop-livestock-forest system (ICLF). The study was carried out in Sinop county, Mato Grosso state, Brazil. Arrangements combining fixed and variable area methods to simple random and systematic sampling were tested. Precision, accuracy, efficiency, and diameter-distribution measurements were used for selection of the best sampling arrangement. The sampling intensity, sample unit optimal size and the relative efficiency have been changed depending on the spatial arrangement for 10% sampling error and 95% probability level. The fixed area method based on systematic sampling, as well as smaller sample units with eight to nine plants (48 m2 to 54 m2) were the most accurate; however, larger plots (192 m2 to 216 m2) were more efficient. All sample units size provided good estimates on the number of trees by diameter classes.

title: Growth and Quality of Leucochloron incuriale Seedlings Subjected to Liming and Phosphorus

description: ABSTRACT Leucochloron incuriale can be used in projects to restore degraded areas and for logging purpose. Soil has been used in nurseries to produce seedlings; however, most soil types in Brazil have low nutrient availability and high acidity level. The aim of the current study is to assess the effect of liming and phosphate fertilization on the growth and quality of Leucochloron incuriale seedlings. Treatments were arranged in factorial design with five base saturation levels – 3.5 (original), 25, 40, 55 and 70% – and six P levels – 0, 120, 240, 360, 480 and 600 mg dm–3 – in completely randomized blocks with four repetitions. The morphological features and their relations were assessed 82 days after planting. Phosphorus levels had significant effect on most of the assessed traits. The recommended P dose was 475 mg dm–3.

title: Formation of Macroaggregates and Organic Carbon in Cocoa Agroforestry Systems

description: ABSTRACT The objective of this study was to analyze the biological contribution to macroaggregate formation under cocoa agroforestry systems, as well as to evaluate the potential of macroaggregates to store carbon. The variation of the populations of macrofauna and the relationship with the morphology of aggregates was monitored in five agroforestry systems associated with cocoa established from different land uses, taking as reference the forest and pasture. Some cacao agroforestry systems favored the presence of macrofauna functional groups similar to the forest (p &lt; 0.05). According to the principal component analysis, the effect of land use on macroaggregate formation is highly significant (p &lt; 0.001) and explained 55% of the total variance. The macrofauna and macroaggregates showed significant covariation (RV = 0.22, p-value = 0.001). Biogenic macroaggregates contained more carbon when they came from agroforestry systems.
