1. ACCURACY OF GENETIC PARAMETERS ESTIMATION AND PREDICTION OF GENOTYPIC VALUES IN EUCALYPTUS USING DIFFERENT PLOT TYPES
ABSTRACT A suitable experimental design should control the environmental effect and be capable of discriminating genotypes. Two clonal tests of Eucalyptus were planted side by side in a randomized block design with the same 32 treatments under two different plot designs. The first trial was designed with five plants per plot (linear plot, LP) and six block r

2. PLANT RICHNESS AND LIFE FORM DIVERSITY ALONG VEGETATION AND FOREST USE GRADIENTS IN NORTHWESTERN PATAGONIA OF ARGENTINA
ABSTRACT The imbalace between the increase in the demand and the decrease in the supply of products from natural forests, partly explains the on-going development of exotic tree plantations. In northwestern Patagonia of Argentina, Pinus ponderosa (Pinaceae) afforestation plays a key role in ameliorate degraded soils, but may also reduce biodiversity. The eco

3. The effect of planting density on ‘BRS Rubimel’ peach trained as a “Y-shaped” system
Resumo O adensamento de pomares tem se tornado uma alternativa viável na busca de maior aproveitamento da área e rentabilidade. Nesse sentido, o espaçamento e o sistema de condução a ser utilizado no plantio de pessegueiro são extremamente importantes para facilitar o manejo do pomar e sobretudo, maximizar a produtividade do pomar. Com base nisso, bus

4. Growth of Eremanthus erythropappus (DC.) MacLeish in Different Planting Spacings
ABSTRACT This study aimed to evaluate the growth of Eremanthus erythropappus (DC.) MacLeish submitted to different planting spacing and growth modelling based on the diameter and crown area projection, as well as to identify the best management strategy to be applied to control the competition, period and intensity of thinning. The evaluated planting spacin

5. MODELOS PREDICTIVOS DE BIOMASA AÉREA DE Eucalyptus grandis PARA EL NORESTE DE ARGENTINA
ABSTRACT Different industrial, environmental and energy interests have led, in recent years, to the analysis of different possibilities for utilization of forest biomass is gaining an increasing role, so that quantification of the biomass from these forest systems is an essential first and an unavoidable step. The aim of this study was to develop models whic

6. Advertisement and release calls of Phyllomedusa ayeaye (Anura: Hylidae) with comments on the social context of emission
ABSTRACT Male calls play different roles in anuran social organization, such as spacing, territoriality and female attraction. However, calls and associated behaviors remain poorly described for many anuran species. Here we describe the advertisement and release calls of the tree frog Phyllomedusa ayeaye (Lutz, 1966) and report on the social context of emiss

7. High coffee population to improve fertility of an oxisol.
The objective of this work was to evaluate the effect of coffee (Coffea arabica L.) population densities on the chemical and microbiological properties of an Oxisol. The work was carried out on soil samples of 0-20 cm depth originated from an experimental site which had been used for coffee tree spacing studies during 15 years, in Parana State, Brazil. Eight

8. Custos de implantação e manutenção e receitas brutas obtidas com o cultivo orgânico de café nos sistemas a pleno sol e consorciado à bananeira e Eritrina.
O objetivo do trabalho foi avaliar os custos de implantação e de manutenção de duas áreas cultivadas com café arábica, uma conduzida a pleno sol e outra arborizada com banana (Musa sp. var.Prata Comum) e eritrina (Erythrina vema) , bem como avaliar a receita bruta obtida nos dois sistemas de cultivo. Ao todo, nove mil mudas pertencentes a seis cultiva

9. DRIS norms for 'Valencia' sweet orange on three rootstocks.
Diagnosis and Recommendation Integrated System (DRIS) applies nutrient ratios instead of the isolated concentration values of each nutrient in interpretation of tissue analysis. The objectives of this research were to establish adequate DRIS norms for 'Valencia' sweet orange irrigated commercial groves budded on three rootstocks and correlate indexes of nutr

10. Dinâmica populacional e efeitos de variáveis ambientais sobre a fauna de pequenos mamíferos em um fragmento de floresta com araucária no sul do Brasil
Natural populations of small rodents fluctuate continually over time and the population dynamics of any living organism are shaped by both intrinsic and extrinsic factors. Small mammals populations can show a continuum dynamic activity, ranging from stability to regular cycles of variable amplitude. The species dynamics is also known to be influenced by the

11. ESTABELECIMENTO DE ESPÉCIES FLORESTAIS NATIVAS, EM ÁREA DE RESTAURAÇÃO CILIAR NO BAIXO RIO SÃO FRANCISCO. / ESTABLISHMENT OF NATIVE FOREST SPECIES IN AN AREA OF RIPARIAN RESTORATION.
The process of environmental degradation that has been occurred in the lower region of Sao Franciscos river is reducing the permanent preservation areas. The artificial regeneration is a method of riparian restoration widely used to reconstitute the native vegetation in degraded areas. For the reasons set was a work of restoration in an area of riparian fore

12. Caracterização da capacidade fotossintética e da condutância estomática em sete clones comerciais de Eucalyptus e seus padrões de resposta ao déficit de pressão de vapor / Photosynthetic capacity and stomatal conductance characterization for seven commercial Eucalyptus clones and their variation due to vapor pressure deficit
This study aimed to characterize the physiological variables related to photosynthesis, in seven commercial Eucalyptus clones with high productivity, by evaluating maximum photosynthetic capacity (Amax), and the response of photosynthesis (A), stomatal conductance (gs) and transpiration (E) to Vapor Pressure Deficit (VPD). A trial was installed in 2004, at E
