title: Development of Forestry Species Inoculated with Trichoderma spp. Fertilized with Rock Phosphate

description: ABSTRACT The study aimed to determine the effects of inoculation of Trichoderma spp. on the development and extraction of nutrients from Eugenia pyriformis Cambess. (uvaieira) and Myrcianthes punges (O.Berg.) (guabiju) subjected to fertilization with rock phosphate. The treatments used at planting were: Control; Trichonat PM®; Trichoderma sp. FS1; Rock phosphate; Trichonat PM® + Rock phosphate; and Trichoderma sp. FS1 + Rock Phosphate. The following characteristics were evaluated at 540 days after planting: plant height, crown diameter, branch insertion points, biomass, and nutrient content. The uvaieiras inoculated with Trichonat PM® and Thrichoderma spp. showed higher vegetative growth and higher values of N, P, K, Ca, Mg and S, respectively. For guabijuzeiros, the treatment with Trichoderma spp. presented the highest insertion point of the branches without phosphorus fertilization However, the treatments did not affect nutrient extraction. Thus, Trichoderma spp. inoculants have the potential to promote vegetative growth and nutrient extraction in plants.

title: Efficiency of Biological Utilization of Micronutrients by Forests Species in Hypoxerophytic Caatinga

description: ABSTRACT The study aimed to estimate the concentrations and efficiency of biological utilization of Cu, Fe, Zn, and Mn and the leaf biomass of ten species in a hypoxerophytic Caatinga fragment, aiming to contribute to a more adequate choice of species for reforestation programs in the Brazilian Caatinga. The leaves of three trees of each species were sampled and the concentration of micronutrients was determined, estimating their content and efficiency of biological utilization. The efficiency of biological utilization followed the decreasing order: Mn &gt; Cu &gt; Zn &gt; Fe. Jatropha mollissima and Spondias tuberosa were less efficient in the use of Fe and Senegalia paniculata and Croton blanchetianus, in the use of Zn. However, Piptadenia stipulacea and Mimosa ophthalmocentra were very efficient in using Fe and Mn. The nutritional efficiency of the species can serve as a criterion for choice of species in forest restoration programs.

title: Community Succession in an Urban Novel Forest after Four Decades of Regeneration

description: ABSTRACT This study aimed to analyse the tree community of an urban forest with 40 years of natural regeneration after abandonment of the degraded land. We hypothesized that after four decades of forest succession, the diversity, structure and functional aspects of the community would be similar to other secondary surrounding forests. We established ten plots (20x 20m), where all trees with DBH ≥ 5 cm were sampled. The inventory included 605 trees (1513 ind.ha-1 ) distributed across 25 species. The diversity index (H’ = 0.92) and basal area (10.43 m2.ha-1) were lower than in surrounding forests. The results showed a great dominance of Eremanthus erythropappus with consequent delay in successional advance, and low potential of attraction of fauna, which suggests the need for management to control its population. Understanding the functioning of novel urban forests and discussing these neglected ecosystems is fundamental to guide management actions for both human and ecosystem prosperity.

title: Vegetation Cover Development Resulting from Different Restoration Approaches of Exploited Mines

description: ABSTRACT The vegetation cover development is an essential step towards the restoration of the ecosystems. In this work, we applied remote sensing to evaluate the temporal development of vegetation cover on exploited mines revegetated with five approaches: natural regeneration, tree plantation, cultivation of trees + herbs, topsoil replacement + tree plantation, and sewage sludge incorporation into mining substrate. Results showed that the natural regeneration approach would require a secular time to provide satisfactory vegetation cover on the exploited mine. Tree plantation required fifteen years to provide 80% of vegetation cover. The use of topsoil + trees or the incorporation of sewage sludge into mining substrates achieved the fastest development of vegetation cover (2.5-5 years) and the highest percentages of revegetated surface (80-95%). However, the floristic composition of vegetation covers is as important as their development, and some restoration approaches are reported to stimulate weed invasion while others prevent it.

title: Are Seeds of Genipa americana L. (Rubiaceae) Tolerance to Water Submersion?

description: ABSTRACT The knowledge of the germination responses of seeds from plants growing along river margins or in areas susceptible to flooding is an important factor in the adoption of restoration practices. Considering that maturation of fruits of Genipa Americana L. when river margins are flooded, we raised some questions: Is seed germination of this species affected by water submersion, and, do distinct seed populations present differences in germination? Seeds of G. Americana were submerged in water for different periods to assess the germination and growing responses, using populations from different locations. Water submersion decreased the germination percentage and the germination speed index, and increased seed mean germination time in both populations. Growth was found to be hampered for most variables in the different seed populations. The adaptation of G. Americana to flooding involves the seeds being tolerant to submersion, with this factor not being effective in distinguishing populations studied here.

title: Topoclimate in Morlet, Cross and Coherence Wavelet Analyses in the Brazilian Cerrado

description: ABSTRACT In recent years, the Traditional Morlet Transform, Cross and Wavelet Coherence have been used as techniques to analyze time series from meteorological and climatic data, obtaining useful information. These techniques were used to study air temperature and relative air humidity, air pressure and wind variables from 2015 to 2017. The data was collected from a micrometeorological station of the Federal University of Mato Grosso State. The objective of the study was to obtain information regarding seasonal trends and effects. The Coherence constituted the normalized spectrum of the TWX, smoothed in time and scale. The seasonality of the region is characterized by the existence of two annual seasons, hot-humid and hot-dry seasons, qualitatively determining the energy levels of the urban cerrado ecosystem.

title: Operational Analysis of Forestry Transportation Using Self-loading Trucks in a Mountainous Region

description: ABSTRACT This research was conducted in wood harvesting and transportation areas in the mountainous region of Espírito Santo, Brazil, aiming to analyze the road transportation of forestry wood operations with self-loading trucks. The study identified and evaluated the times, average speed, mechanical availability, level of use and operating efficiency of three different designs of self-loading trucks. According to the results, there was no statistical difference between the vehicles regarding average speed. The highest mechanical availability was found in truck A (93.2%), followed by B (84.3%) and C (79.8%). The greater degree of utilization was found in truck B (91.8%), with little variation between vehicles C (90.0%) and A (89.9%). The highest operating efficiency was observed in truck A (83.9%), followed by B (77.4%) and C (71.8%). We concluded that self-loading truck A was the most efficient.

title: Elastic and Osmotic Adjustment of Talipariti elatum (Sw) Frixell Grown in Organic Substrates

description: ABSTRACT The aim of the present study was to evaluate the water response of Talipariti elatum cultivated in different substrates. Sugarcane straw, peat, biochar and mixtures of sugarcane straw and biochar, and peat and biochar were used. The physical properties of each substrate and the water parameters of the species were determined based on the pressure-volume curve. The osmotic potential at maximum saturation and the turgor loss point presented a similar behaviour with a decreasing tendency. We found significant differences between the beginning and end of the period. The values ranged from -1.17MPa to -1.36MPa and -1.49MPa to -1.74MPa, which indicated the development of osmotic adjustment mechanisms. The modulus of elasticity values ranged between 8.10MPa and 11.20MPa at the start and between 6.65MPa and 9.39MPa at the end, indicating elastic adjustment. The plants in the substrates with lower moisture retention showed lower values of solute potentials and cell wall elasticity modulus.

title: Technologies for Jatoba Seedling Formation

description: ABSTRACT This research evaluated protected environment and substrates for jatoba seedling. Two protected environments were used: (i) black shading screen on the sides and roof; and, (ii) black shading screen on the sides and thermal-reflective aluminized screen on the roof. In each environment the following substrates formulated with cattle manure (M) and vermiculite (V) were tested: 100% M; 90% M + 10% V; 80% M + 20% V; 70% M + 30% V; 60% M +40% V; 50% M + 50% V; 40% M +60% V; 30% M + 70% V; 20% M + 80% V; 10% M + 90%V. The environment protected with black shading screen was more favorable for the formation of jatoba seedlings, resulting in seedlings with higher shoot height and root collar diameter and, therefore, higher quality. Recommendation is to use substrates containing up to 30% of cattle manure to produce high quality jatoba seedlings.

title: Development of Mathematical Programming Model for Cable Logging System Location

description: ABSTRACT Defining the optimum points for installing of a cable logging system is a problem faced by forestry planners. This study evaluated the application of a mathematical programming model for optimal location of cable logging in wood extraction. The study was conducted in a forestry company located in Parana State, Brazil. We collected data during timber harvesting and developed mathematical models to define the optimal location of the cable logging considering the variables “cycle time” and “extraction distance”. The variable “cycle time” affected the definition of the optimal location of equipment resulted in a reduced number of installation points with the largest coverage area. The variable “distance extraction” negatively influenced the location, with an increased number of installation points with smaller coverage. The developed model was efficient, but needs to be improved in order to ensure greater accuracy in wood extraction over long distances.

title: Lumber Yield of Four Native Forest Species of the Amazon Region

description: ABSTRACT The objective of this study was to evaluate the volumetric lumber yield of four native species of the Amazon Region: Cedrinho (Erisma uncinatum Warm), Cumaru ( Dipteryx odorata Aublet), Garapeira (Apuleia leiocarpa Voguel), and Cambará (Qualea paraensis Ducke). Twelve logs of each species with different diameters were randomly selected from different sawmills in northern Mato Grosso state, Brazil. Additionally, the influence of diameter on the yield of each species was evaluated through regression analysis. Among the evaluated species, Cedrinho obtained the highest yield values, followed by Garapeira. Cumaru and Cambará showed the lowest yields, and did not differ statistically. Log diameter negatively influenced lumber yield, except for Cumaru wood, which did not present a clear relation between these parameters.
