Streszczenie:

Structural and floristic features of the rainforest-eucalypt forest boundary are described for two sites on the seasonally clouded eastern slopes of the Herberton Highland, north Queensland. Permanent sample plots, transects and canopy profiles were used to analyse variations across the narrow ecotone. The forest ecotone was found highly variable, spatially and temporally. Within rainforest, richness of woody species was maintained through to the closed forest edge. However, structural changes were more pronounced towards the boundary than were floristic variations and a fringe of immature rainforest varied in depth from 20-500 m. In the open forest margin, tall trees of Eucalyptus grandls were restricted to a narrow zone between the rainforest edge and the broad expanse of medium height Eucalyptus intermedia. Within this transition, young rainforest trees and some shrubs were observed, during a 12-year interval, to be establishing beneath tall E. grandis, displacing fire-prone grasses in the process. The distribution of old E. grandis within rainforest provides a record of recent boundary change. On evidence presented, the rainforest-eucalypt forest boundary is dynamic and parts of the rainforest are expanding due to favourable contemporary fire regimes.

The aim of the study is to evaluate the role of the Grand fir (Abies grandis [Dougl. ex D. Don] Lindl.) as a soil-improving species in the area of the University Training Forest in Kostelec nad Černými lesy, Jevany district. The state of humus forms in the stand part with Grand fir was compared with the mature Norway spruce (Picea abies [L.] Karst.) without regeneration, with young beech (Fagus sylvatica L.), Norway spruce (Picea abies [L.] Karst.) and oak (Quercus spp. L.) stands (all of pole stage). The site is characterized as 4P1 – acid oak-fir site with Luzula pilosa, the geological bedrock is formed of cretaceous sandstone with loess overlays, the soils are Luvisols, the terrain is flat at the altitude of 420–440 m a.s.l. The humus form samples (L, F, H, Ah horizons) were taken in 4 replications, quantitatively for the holorganic layers. The dry mass amount and total nutrient contents were analyzed for holorganic horizons, the basic pedochemical characteristics (pH, soil adsorption complex characteristics, exchangeable acidity and exchangeable nutrients) were determined for all horizons. The results confirmed marked and positive effects of the Grand fir litter on the surface layer characteristics. This tree species supports the litter of good composition, transforming easily and forming humus forms of higher quality compared to coniferous as well as studied broadleaved species.

Streszczenie:

To mitigate erosion after fire, land managers often seed non-native grasses onto burned slopes. To assess how post-fire seeding affects plant recovery, we compared areas that were either unseeded or artificially seeded after high-intensity fire in a dry Abies grandis (Dougl.) Lindl. forest in the northeastern Cascades. Seeding with a mix of non-native grasses and a legume significantly reduced the cover of native plants and shifted patterns of relative abundance after 2 years. Although seeding did not significantly affect total cover or native species richness, it reduced overall native plant cover by 47%. Species that recolonize via wind-dispersed seeds (e.g., Epilobium angustifolium L., Lactuca serriola L., and Arenaria macrophylla Hook.), species with long-lived seeds that germinate after fire (e.g., Ceanothus velutinus Dougl.), and species with wide successional amplitudes that resprout after fire (e.g., Apocynum androsaemifolium L. and Salix scouleriana Barratt) all declined steeply in cover on seeded plots. In addition, conifer seedlings were only half as abundant on seeded plots. As seeding after fire does not boost total plant cover and limits conifer tree establishment on the study area, it appears to do little to reduce the risk of soil erosion. It also appears to inhibit native shrub and herb re-establishment. These substantial effects on native species appear to alter plant communities well beyond the life of the seeded species.

Banksia grandis is a major understorey component of the jarrah forest and is a refuge of the soil fungus Phytophthora cinnamomi which kills many native plant species and threatens timber production. This paper presents data on the rate of growth of the lignotuber, shoot and stem of B. grandis. Length of the seedling lignotuber increased 0.23 cm year-1 over 3 years, that of saplings and trees increased 0.44 cm yea-1. The period for a seedling to attain 1.3 m height was calculated as c. 15 years. Short-term diameter increment of trees averaged 0.19-0.27 cm year-1, indicating that diameter at breast height of 20 cm should be attained in c. 80-100 years; this estimate is also supported by direct and indirect long- term data. Watering, shading and spraying with insecticide had no significant influence on height growth of saplings. Four years after fire, sapling coppice from large lignotubers nearly attained the height of the plant before the fire. Trees, but not saplings, grew faster after logging of forest. The significance of these growth rates is discussed in relation to two methods (mechanical removal, moderate-intensity fire) proposed to reduce the abundance of B. grandis in the jarrah forest.

The purpose of this study was to assess the volume increment diversification of selected provenances of grand fir growing under mountain conditions of Poland. The mean increment was determined on the basis of volume reached by the respective provenances when trees were 30 years old while the current increment was calculated from a difference between the volume when trees were 30 years old and the volume when they were 26 years old. It was found that the productive (increment) potential of tested grand fir partial populations is determined by the genotype (provenance). Among the tested provenances grand fir from Salmon River on Vancouver Island in Canada is characterized by the greatest productive capacity.

Recently, there has been an interest in potential of antioxidant film incorporated with natural extract. The film was produced by using chitosan in the presence of pomelo (Citrus grandis) peel extract. In this study, there were 3 different effects of parameter that had been screened by using 2-Level Factorial which were concentrations of chitosan, pomelo peel extract and glycerol. Meanwhile, the response that had been investigated which was Total Phenolic Content (TPC). The data were analyzed by using ANOVA to screen the parameters affecting the antioxidant activity of films. Factor B (concentration of pomelo peel extract) and AC (interaction between the concentration of chiotosan and glycerol) were significant parameters in this studied. Meanwhile, FTIR spectra of antioxidant film revealed that there were interaction between functional groups of chitosan with pomelo peel extract with presence of aromatic ring C=C stretch at wavelength of 1555.3 cm-1 and 1410.7 cm-1. These results suggested that chitosan films containing pomelo peel extract have potential as the antioxidant thin film, which can be used for development of antioxidant food packaging materials.

Streszczenie:

Wildfires can affect ecosystem structure and threaten human lives. Understanding fire behavior and predicting fire activities is a crucial issue to mitigate fire impacts. Machine Learning is currently an important tool for the modeling, analysis, and visualization of environmental data and wildfire events. In this study, we assessed the performance of two machine learning algorithms for modeling and predicting fire intensity, the height of flames, and fire rate of spreading in Eucalyptus urophylla (Myrtaceae, Myrtales) and Eucalyptus grandis (Myrtaceae, Myrtales) plantations spatially located in Viçosa - MG, Brazil. The Random Forest showed to be the best algorithm for fire modeling, with climatic conditions, and moisture of the combustible material being the variables that significantly affect the prediction of fire behavior.

Estudos mostram que diplomas de nível superior facilitam o acesso a posições de trabalho mais bem remuneradas e são uma fonte importante de prestígio e honra social no Brasil. Não obstante, uma ampla literatura afirma hoje a diminuição da importância do diploma nos processos de contratação, argumentando que ele seria cada vez menos suficiente para se conseguir um emprego. Este artigo examina os processos de seleção de engenheiros recém-formados por oito grandes empresas da região de Campinas. Com base em entrevistas com os principais atores da seleção e em observações das rodadas iniciais de uma seleção realizada por firma de consultoria contratada por uma das empresas, o estudo mostra que o peso do diploma obtido em uma universidade de prestígio ainda é a variável mais importante na decisão de contratação, definindo não apenas a obtenção do emprego, mas também o acesso às vagas que levam às posições gerenciais, mais bem remuneradas e mais prestigiosas. Ao final, discute as implicações teóricas e o que esses resultados sugerem em termos de políticas públicas.

Abstract There is considerable merit in thinking of the modern multidivisional corporation as an economy within itself. There is an important similarity between the interaction of divisions within a corporation and the perfectly competitive economic model formulated by Leon Walras1. When we look at modern corporations from this viewpoint we discover that much of what we know in general equilibrium economics may have considerable application inside modern corporations. Some of our existing theorems help clarify distinctions between decentralization and central control in corporate management in the same way that they clarify the distinctions between the market economies and those that run by central decree. They help distinguish which divisions must be centrally managed and those which can be left to look after themselves. This viewpoint offers new insights too—that, for instance, the products transferred between divisions may quite logically have two transfer prices instead of one. This viewpoint also permits an easy synthesis of the existing literature on transfer pricing. While the transfer pricing issue is especially important for multinational and international corporations which transfer goods and services between divisions located in different countries, the principles generally apply to any multidivisional corporation. The purposes of this paper are to present a simple, but general analytic model of the multidivisional corporation, to use it to make a synthesis of the existing literature on transfer pricing, and to make some important new discoveries. 1 Léon Walras, Elements of Pure Economics, édité et traduit par W. Jaffe (London : George Allen and Unwin, 1954). Kenneth Arrow fait mention de cette similitude dans son article : « Optimization, Decentralization and Internal Pricing in Business Firms », Contributions to Scientific Research in Management, 9-18, Western Data Processing Centre, Los Angeles, University of California Press, 1961.

Dry mixed-conifer forests are widespread in the interior Pacific Northwest, but their historical fire regimes are poorly characterized, in particular the relative mix of low- and high-severity fire. We reconstructed a multi-century history of fire from tree rings in dry mixed-conifer forests in central Oregon. These forests are dominated by ponderosa pine (Pinus ponderosa Lawson & C. Lawson), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), and grand fir (Abies grandis (Douglas ex D. Don) Lindl.). Across four, 30-plot grids of ∼800 ha covering a mosaic of dry mixed-conifer forest types, we sampled 4065 trees for evidence of both high- and low-severity fire. From 1650 to ∼1900, all four sites sustained frequent, often extensive, low-severity fires that sometimes included small patches of severe fire (50–150 ha during 18%–28% of fire years). Fire intervals were similar among sites and also among forest types within sites (mean intervals of 14–32 years). To characterize the continuous nature of the variation in fire severity, we computed a plot-based index that captures the relative occurrence of low- and high-severity fire. Our work contributes to the growing understanding of variation in past fire regimes in the complex and dynamic forests of North America’s Interior West.

ABSTRACTZinc borate has long been used as a protector for wood products due to its fungicide, insecticide and flame retardant properties. In this initial study, its capacity as a flame retardant when applied to Eucalyptus grandis wood is evaluated; micronized zinc borate, synthesized from zinc oxide and boric acid in our laboratory was used. The methodology used in the study is the use of the Vandersall tunnel, which allowed analyzing parameters such as the flame spread, the carbonization index, the carbonization area and the wood weight loss. The results show a remarkable improvement in these parameters after the application of micronized zinc borate. For the longest fire exposure time, the percentage decrease of each evaluated parameter is, for tangential and radial plane respectively: 31.27-43.00% for flame spread, 36.66-40.86% for carbonization area, 33.01-52.49% for carbonization index and 19.86-57.80% for mass loss.

Streszczenie:

Vegetation maps were prepared from aerial photographs taken in 1943?45 and 1991?92 of three, widely separated areas of sclerophyll forest adjacent to the western edge of rainforest on granitic soils in north Queensland. Nine types of sclerophyll communities could be discerned from aerial photos and characterized by field measurement. Two types of Wet Sclerophyll Forest (WSFa and b) were separated on the species of tree composing the tallest stratum and these were subdivided according to whether the ground layer was dominated by grass or young rainforest. A related type showed large, residual Eucalyptus grandis emergent from mature rainforest. Closed canopy sclerophyll forest with no emergents (SF), sclerophyll woodland and Acaciaforest were also discerned. WSF was defined as having more than 30 per cent of the closed crown cover contributed by trees more than 35 m tall. During the 50-year study period rainforest invaded 70 per cent of WSFa (tallest stratum dominated by E. grandis), which principally occurs as a narrow strip along the rainforest margin, and 57 per cent of the adjacent WSFb (tallest stratum composed of mixed species). Grass would be quickly excluded from invaded areas and thereafter they would only burn under extreme atmospheric conditions. Because sclerophyll trees are unable to regenerate in shade and usually require fire to provide the appropriate conditions, a long-term transition to rainforest may ensue. The final stages of this transition were observed in areas that exhibited full-stature rainforest with large, relictual E. grandis emergents in 1943, but had disappeared by 1992. The initial cause of this vegetation transition is a fire-free period of sufficient length for rainforest tree seedlings to establish and suppress the grass layer. It is not known whether these vegetation changes represent a trend, possibly caused by a change a century ago from fire management by Aboriginal people to management for the cattle industry, or whether it is a temporary phase in the fire-induced, dynamic relationship between rainforest and sclerophyll vegetation. The current loss of WSF probably endangers the survival of a range of genetically endemic biota. Most groups are poorly known but the marsupial Yellowbellied Glider Petaurus australis reginae is totally dependent upon WSF and a number of vertebrates would probably go locally extinct if WSF is replaced by rainforest. WSF is the wettest part of the sclerophyll communities and probably acts as a refuge in times of unusual aridity. To maintain the WSF habitat, fire management is clearly indicated, but the intensity of fire required to reverse the advance of rainforest may be socially unacceptable to instigate or impossible to control if it occurs by accident.

Este trabajo es una introducción a la discusión sobre el papel que juegan las empresas grandes y pequeñas en los procesos de innovación que se llevan a cabo en las industrias del conocimiento. El análisis se realiza desde la perspectiva de la tradición schumpeteriana-penrosiana. Se presenta un modelo donde el tamaño de la firma tiene implicaciones importantes para los diferentes momentos en que se llevan a cabo los procesos de innovación. Una conclusión importante en este trabajo es que las empresas pequeñas tienen una gran capacidad de respuesta ante los cambios tecnológicos. Sin embargo, las restricciones financiaras constituyen una limitante para el desarrollo de innovaciones en las empresas pequeñas. Desde esta perspectiva, las alianzas y la cooperación entre las grandes y las pequeñas empresas son una explicación adecuada que surge cuando analizamos la actividad innovadora en las industrias del conocimiento. El trabajo también presenta algunos resultados empíricos sobre el comportamiento de las industrias relacionadas a la biotecnología en Canadá a manera de demostración empírica de este enfoque teórico.

AbstractThis paper argues that “insider” material, preserved by the Armenians in the archives of the cathedral in New Julfa presents, by virtue of its logic, a one-sided, consensual picture. “Outsider” material contests this view and highlights the underlying conflicts of interest that even existed among the core members of the network. The picture that emerges from this study points to a more dynamic, complex structure in which the multiple interests of individual members of family firms, kin, and community members in different capacities were grafted into one. Loopholes in the system were visible as early as the 1720s, long before the center at New Julfa collapsed. Les archives arméniennes ont été conservées dans la cathédrale de la Nouvelle Julfa. Ces sources “internes” présentent, selon nous, une image partiale de consensus. L'examen minutieux des sources “externes” par contre fait ressortir des conflits d'intérêts même entre les grands négociants du réseau arménien. Ces documents-là attestent des structures complexes plus dynamiques. Dans ce cadre s'inscrivaient les multiples intérêts des membres individuels de la firma familiale, des parents, et des membres de la communauté. Et les faiblesses du système sont déjà perceptibles dans les années vingt du XVIIème siècle, bien avant l'effondrement de son centre à la Nouvelle Julfa.

AbstractThe research investigated changes in post fire density and strength properties of Nigerian wood species used for construction. The selected species are: Terminalia superba (Afara), Milicia excels (Iroko), Nauclea diderrichii (Opepe), Khaya ivorensis (Mahogany), Mansonia altissima (Mansonia), Tectona grandis (Teak). Densities and strength properties of the species were determined at Moisture Contents (MC) of 9.0, 12.0, and 15.0%. Species were exposed to fire at various temperature ranges. The results revealed that at 9, 12 and 15%MC, Opepe had the highest density values of 630±28.85kg/m³, 686±22.64kg/m³ and 752±17.22 kg/m³ respectively. At 9%MC, Mahogany had the lowest density (439±10.58kg/m³) while at 12 and 15%MC, Afara had the lowest density values of 444±4.18kg/m³ and 469±7.07kg/m³ respectively. Post fire exposure revealed that Afara had the highest percentage loss in density 29.2% and strength properties, while both Iroko and Mahogany exhibited the lowest percentage loss in both density and strength properties.

This paper examines seed release and seed dispersal; recruitment in relation to fire and logging; mortality of seedlings in relation to their age; and the dynamics of one population from November 1979 to March 1983. Dehiscence of follicles is caused by wetting and drying of the infructescence, so that most seeds fall to the ground during autumn in the Mediterranean climate of south-western Australia. Seeds are wind- dispersed, settling downward from the parent tree: 90% of seed falls within the first year. There is large variation in annual recruitment of seedlings, reflecting large annual differences in the number of infructescences produced. Fires of various intensities or logging do not enhance recruitment. Seedling mortality is greatest during the first summer after germination; this may be related to the rudimentary development of the lignotuber. A population of 1890 individually marked plants was studied for 3.5 years. Over twice as many deaths took place in summer and autumn as in winter and spring, and 90% of deaths were of plants less than 20 cm tall. At the conclusion of the study, total population size, through recruitment of three cohorts of seedlings, had increased by 7%. This indicates how important control of reproduction would be in achieving long-term reduction in the abundance of B. grandis, which harbours the pathogenic fungus Phytophthora cinnamomi.

In the empirical part we check for a sample of companies in the Catalonia metal sector with at least 100 employees, if several modalities about functional flexibility are implemented. Mainly the job rotation, autonomy over work, and delegate indirect tasks to the operator. In addition also the modalities of variable pay for the operator. The individual and joint application of the items is analyzed, making a descriptive statistical analysis and bivariate association. In most companies operators are intensively responsibles for the order and clean their workplace, as well as self control, followed by prepares the machine, to search the origin of defects and their solution. Almost half firms haven’t incorporated teamwork, while cross functional teams and improvements teams are more incorporated, although the proportion that applies a high degree is low. The operator does not usually engage in maintenance of machinery nor collaborate in the development and improvement of the standard. There are limited autonomy in work organization and planification, fixing work methods and rhythm of work. The wage flexibility is low, although the pay for performance/productivity is the modality most used. The pairs of modalities of wages that are significantly are the incentives: “to fulfill team goals” and “quality”, “profit sharing” and “knowledge / skills /abilities “. Moreover it is tested whether there are significant differences according to central tendency of various items (rhythm of work, stress level, absenteeism level as well as the ratios: percentage of variable pay, labor productivity, ROS, and personnel costs/revenues) segmented according to the modality functional flexibility or wage flexibility considered. The main conclusions are that rhythms of work and absenteeism are lower when job rotation is reduced, there aren’t significant differences in productivity, but there are differences in central tendency measures of the profit margin when segmenting by the items: autonomy in work organization and planification, rhythm of work, self control, order and clean, and operator maintenance of machinery. The value of this ratio is lower when such items are reduced. Few companies incorporated most labor practices intensely. Therefore, most firms require greater joint incorporation of labor flexibility dimensions to achieve complementarities and synergies. Homals analysis is used to establish relationships between more than two qualitative variables and reduce the dimensionality by incorporating measures of discrimination. The first dimension includes mainly: the operator is responsible of seeks the origin of defects, to solve the defects found, to program the machine, the basic maintenance of the machine and analyzed data. The second dimension includes: teamwork in the production area, teams improvement voluntary, the operator involvement in continous improvement and cross teams to solve problems. We identify a typology of firms, using cluster analysis with the results of Homals. No significant differences were obtained when segmented by the 10 groups offered by the cluster.

As lianas, ou trepadeiras lenhosas são importantes componentes estruturais de muitos ambientes florestais. O estudo objetivou investigar os aspectos florísticos e ecológicos de grandes lianas em três ambientes florestais de terra firme na Amazônia Central (2º35' S e 60º12' W). Para o levantamento florístico, foram alocadas 20 parcelas de 50 x 10 m em cada um dos ambientes florestais (platô, vertente e baixio), nas quais foram mensurados todos os espécimes lianescentes com diâmetro à altura do peito (DAP) > 10 cm. Na floresta de platô foram inventariados 17 indivíduos, pertencentes a nove famílias, dez gêneros e treze espécies. Fabaceae e Combretaceae foram as famílias com maior número de espécies, representando juntas mais de 46% do total amostrado. As espécies com os maiores Índices de Valor de Importância (IVI) foram Doliocarpus brevipedicellatus Garcke (IVI = 55,2) e Abuta candollei Triana & Planch. (IVI = 33,3). Um total de doze espécimes, compreendendo quatro famílias, quatro gêneros e oito espécies foram registrados na floresta de vertente. Nesse ambiente florestal, Caesalpiniaceae foi a família mais rica, representando cerca de 38% das espécies identificadas. Abuta rufescens Aubl. (IVI = 68,8) e Bauhinia alata Ducke (IVI = 49,2) foram as espécies com os maiores valores de importância. Na floresta de baixio foram registrados quatro indivíduos, distribuídos em quatro famílias, quatro gêneros e quatro espécies. Nos três ambientes florestais estudados, sete indivíduos atingiram DAP > 20 cm. Quanto às espécies, a similaridade florística entre os ambientes florestais foi muita baixa, com a menor dissimilidaridade anotada entre as florestas de vertente e baixio (Is = 0,17). Nesse estudo, de acordo com os índices de diversidade de Shannon-Wiener, Simpson e alfa de Fisher, a floresta de platô mostrou-se mais diversa em lianas de maior porte que as florestas de vertente, o mesmo ocorrendo quando comparado com os dois primeiros índices de diversidade em relação ao baixio.

This article summarizes basic estimates of productivity and trend analysis of one of the principal introduced forest tree species in the Czech Republic, i.e. Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco). As a comparison, we also examine grand fir (Abies grandis [D. Don] Lindl), northern red oak (Quercus rubra L. syn. Quercus borealis Michx.) and black locust (Robinia pseudoacacia L). This paper presents estimates of forest land area, standing volume, annual and total increments, distribution of age classes, average ages and site indexes for the period 1979–2010. All data were obtained from the national forest inventory of the Czech Republic. Korf’s growth function was used for the assessment of current and mean annual increments (CAI, MAI) of Douglas-fir compared to other tree species. Our results suggest a decline in the annual area afforested by Douglas-fir, as influenced by the State administration management choices, a low rate of an increase in the forest land area, increasing average age of the forests. On the other hand, we observed a dramatic increase in the standing volume as well as high annual increments in volume. Douglas-fir is the most productive major tree species in the Czech Republic and there is a great potential to expand its use throughout the country.

Streszczenie:

In 1998, a forest fire burned 58% of the forested shoreline surrounding Tibbitt Lake, Northwest Territories, including riparian vegetation used by Northern Pike (Esox lucius) as spawning habitat. This presented an opportunity to investigate the effects that habitat disturbance from a natural forest fire had on young-of-the-year (Y-O-Y) Northern Pike. Pike fry were collected from three burned and three unburned sites around Tibbitt Lake in 1999 (the first post-fire spawning season) and again in 2001. Differences in size and relative abundance were evaluated between sites. Y-O-Y Northern Pike were significantly larger at the unburned sites (P<0.01) and the relative abundance of Y-O-Y Northern Pike increased significantly at burned sites (alpha=0.1; P<0.07) following re-vegetation two years post fire. These differences may be due to fire-induced changes in physical habitat or food availability. Forest fires decrease the density of riparian vegetation, which likely provides better spawning and rearing habitat for Northern Pike in the long-term.En 1998, un feu de forêt a brûlé 58% de la rive boisée entourant le lac Tibbitt, situé dans les Territoires du Nord-Ouest, y compris la végétation riveraine utilisé par le grand brochet (Esox lucius) comme habitat de fraie. Cet événement a présenté une occasion pour étudier les effets causés par un feu de foret sur l'habitat de jeunes de l'année du grand brochet. Les jeunes brochets ont été recueillis sur trois sites brûlées et trois sites non brûlés autour du lac Tibbitt en 1999 (la première année de fraie après le feu de forêt) et à nouveau en 2001. La différence de grandeur et l'abondance relative des poissons ont été analysés entre les différents sites. Les jeunes grands brochets aux sites non-atteints par le feu étaient considérablement plus grands (P < 0,01) que ceux aux sites brulés. Les sites brulés, subissant une rapide revégétation dans les deux années après le feu, ont augmenté en abondance relative de jeunes grands brochets (alpha = 0,1, P < 0,07). Ces différences peuvent être dues aux changements induits par le feu sur l'aspect physique de l'habitat ou sur la disponibilité de nourriture. Les incendies de forêt réduisent la densité de la végétation riveraine, qui fournit probablement de meilleure habitat de fraie et d'alevinage pour le grand brochet à long terme.

Streszczenie:

Heat content with and without ash was measured for foliage of three interior Pacific Northwest conifers (Pinus ponderosa, Pseudotsuga menziesii, and Abies grandis/concolor) in five locations in Oregon and Washington. Heat content with ash did not vary by species (20.47–20.59 MJ kg–1), but ash content did vary, so that heat content without ash varied by species. Heat content also varied by location but, due to confounding with season, these differences should be viewed with caution. Foliar heat content values averaged about 10% higher than those used for surface fuels in standard fire behavior fuel models. If heat content is included in future models of crown fire behavior, errors in using heat contents that are too low may have a larger impact than most errors in estimating foliar moisture content, but sources of error might be overwhelmed by other errors in estimating crown fire energy balance.

Los mayores agentes económicos en Indonesia son industrias gubernamentales y grandes corporaciones. Los grandes negocios son dominados por un grupo de familias poderosas; estos tienen un alto nivel jerárquico y centralizado. La toma de decisiones es controlada por la alta gerencia, usualmente por el fundador de la firma o por un miembro clave de la familia. El consenso, la armonía, y la lealtad son muy importantes entre los grupos de negocios. La corrupción fue y sigue siendo un serio problema que afecta los diferentes niveles del gobierno y los procesos en los negocios.

The article aims to evaluate the research provenance plot established in 1980 in locality No. 214 – Hrubá Skála (in the north of the Czech Republic), where nine provenances of grand fir (Abies grandis (Douglas ex D. Don) Lindley) provided in the framework of the International Union of Forest Research Organizations project, and one provenance of grand fir, Norway spruce, silver fir and Douglas-fir from a standard commercial source are tested. We present the results of tree height, stem DBH, stem volume production and health status after 36 years. The results correspond with similar experiments in the Czech Republic and abroad and suggest that grand fir provenances from Vancouver Island (British Columbia, Canada) and the Washington (USA) State coastal region show the best production features, while the Oregon Cascades, Idaho and Montana provenances grow more slowly. Comparison with other tree species indicates that the production of grand fir at the investigated age exceeds the production of both Norway spruce and silver fir, and equalizes or gently exceeds even Douglas-fir.

Streszczenie:

The sustainability of exotic commercial plantations is dependent on the conservation of soil nutrients, especially on the ancient, leached soils of the tropics, particularly when limited fertilization is practiced. In Eucalyptus grandis W. Hill ex Maid. plantations in South Africa, the site is usually burned following harvest and prior to replanting, potentially causing a disruption of soil faunal function and losses of nutrients associated with burning and removal of slash residues. The aim was to study the effect of fire on nutrient dynamics and invertebrate faunal composition. The in situ nitrogen and phosphorus mineralization rates and invertebrate faunal composition were measured in six randomly located plots — three burned and three unburned — prior to and after a low-intensity fire. Results indicate that within the burned plots, phosphorus availability was enhanced 10-fold within the first month following the fire. Invertebrate faunal diversity was low both prior to and after burning, with ants constituting the highest number. Invertebrate faunal composition was more markedly influenced by season than by the fire, with millipedes present in the majority of plots in spring and ants dominating in summer.
