Pinus Taeda L

Background: Taper modelling and volume estimation are key procedures in the management and planning of plantedforests. The objective of this work was to evaluate the taper and volume behaviour of Pinus taeda L. species, along the stemin different ages, using the Preussner taper functions, compared to Schöpfer’s 5th-polynomial, Kozak’s and Max-Burkhart’smodels. This work focused on plantations of Pinus taeda L., due to its wide use as a source of raw material in the forestindustry of southern Brazil. Methods: The data were collected in the last 22 years from the Midwest region of Santa Catarina, of trees ranging in agefrom 3.5 to 18 years. This dataset consisted of a collection of volume sections, with relative diameter measurements alongthe stem, used in conventional forest inventory. The total volume of the trees, obtained by integrating the Preussner taperfunctions, was equated by dividing the stem into four parts, in which parabolas were fitted, and compared with the totaland merchantable volume estimated by Schöpfer’s 5th-degree polynomial, Kozak’s and Max-Burkhart’s functions. Results: Bias, RMSE and r were generally better with the application of Kozak’s model, and AIC and BIC for the Preussner’smodel. Conclusions: Kozak functions were better to provide the merchantable volume. In terms of total volume both functions,Kozak and Preussner, provided reliable estimates. The advantage of the procedure proposed by Preussner is the flexibilityof the fitted taper functions, the simplicity of volume calculations by integration, and the feasibility for interpreting theircoefficients.

The dynamics of the production, chemical composition, and accumulated nutrients in litterfall are essential to understand the availability of nutrients and, consequently, possible gains in productivity in different forest types. Thus, the objective of the present study was to evaluate the litterfall and the accumulated nutrients in litterfall in a Pinus taeda plantation and native forest from southern Brazil. Two forest types: (i) an eight-year-old Pinus taeda L. plantation; and (ii) a native forest fragment, located in southern Brazil, were studied for four years. The monthly and annual litterfall production, chemical composition, accumulated nutrients, and nutrient use efficiency of the litterfall were evaluated. The Pinus taeda plantation showed higher values of leaves/needles litterfall and N, P, K, Ca and Mg use efficiency. This demonstrates that Pinus taeda plantations have a high production of needle biomass, which, in turn, has increased cell division, favoring the entry of these nutrients into the soil via decomposition. Our results show that total litterfall production did not significantly influence the accumulated nutrient and nutrient efficiency of litterfall, demonstrating that evaluating litterfall fractionation, such as leaves/needles, twigs and miscellaneous, is essential to understand the quantity and quality of litterfall and, thus, the nutrient cycling, which can contribute to possible silvicultural practices to be implemented, which can provide growth gains in forest types.

ResumoAs formigas cortadeiras pertencentes ao gênero Acromyrmex (Hymenoptera: Formicidae), representam um dos principais problemas do empreendimento florestal no Brasil. Estudos objetivando determinar a ocorrência e os danos causados por essas formigas em áreas de plantio de Pinus na região Sul do Brasil são escassos. Os principais objetivos desta pesquisa foram a determinação da densidade de ninhos em áreas de plantio de Pinus taeda L. com e sem controle químico e a quantificação de plantas atacadas. Os estudos foram conduzidos no período de janeiro a junho de 2010. O experimento foi instalado em uma fazenda situada no município de Anita Garibaldi (SC). Foram demarcadas quatro parcelas de 0,5 ha, sendo que duas receberam um combate pré-plantio com isca formicida e duas não. Após o plantio, foram realizados censos quinzenais em cada parcela. Constatou-se a ocorrência de formigas das espécies Acromyrmex crassispinus Forel 1909 e Acromyrmex heyeri Forel 1899. Os danos totais médios por hectare causados às mudas foram no máximo de 3,0% no 35º dia e de 5,38% no 63o dia de avaliação. Os controles às formigas podem ser diminuídos se forem levados em consideração época do plantio, densidade dos formigueiros e porcentagem de danos causados às mudas.AbstractAssessment of damages caused by leaf-cutting ants of genus Acromyrmex (Hymenoptera: Formicidae) in plantations of Pinus taeda in Santa Catarina southern highlands. Leaf-cutting ants of genus Acromyrmex (Hymenoptera: Formicidae) represent one of the main problems of forest enterprise in Brazil. Researches aiming to determine occurrence and damage caused by such ants in areas of pine plantation in southern Brazil are scarce. The main aims of this research were determining density of nests in Pinus taeda L. planted areas with and without chemical control, and quantification of attacked plants. The research was developed from January to June 2010. The experiment was set up on a farm in the municipality of Anita Garibaldi, SC. Four plots of 0.5 ha were marked out, two received a pre-planting to combat ant bait, and two others not. After planting, censuses had been managed biweekly to each plot. It revealed the occurrence of the following ant species: Acromyrmex crassispinus Forel 1909 and Acromyrmex heyeri Forel 1899. The average total damage caused to seedlings per hectare reached the maximum of 3.0% at the 35th day, and 5.38% at the 63rd day of evaluation. Ants control can be decreased if it is considered  planting time, density of nests and  seedlings damage percentage.Keywords: Ant; ant bait; chemical control.

Abstract A consensus map for loblolly pine (Pinus taeda L.) was constructed from the integration of linkage data from two unrelated three-generation outbred pedigrees. The progeny segregation data from restriction fragment length polymorphism, random amplified polymorphic DNA, and isozyme genetic markers from each pedigree were recoded to reflect the two independent populations of parental meioses, and genetic maps were constructed to represent each parent. The rate of meiotic recombination was significantly greater for males than females, as was the average estimate of genome length for males {1983.7 cM [Kosambi mapping function (K)]} and females [1339.5 cM(K)]. The integration of individual maps allows for the synthesis of genetic information from independent sources onto a single consensus map and facilitates the consolidation of linkage groups to represent the chromosomes (n = 12) of loblolly pine. The resulting consensus map consists of 357 unique molecular markers and covers ∼1300 cM(K).
