Showing papers in "Forest Ecology and Management in 2001"

TL;DR: In this article, a meta analysis of the literature on forest management effects on soil carbon (C) and nitrogen (N) is presented. But the results of the meta analysis are limited to coniferous species.

TL;DR: In this article, the authors highlight the main biotic and abiotic factors that influence the patterns of Neotropical secondary forest successions, referred as the woody vegetation that regrows after complete forest clearance due to human activities.

TL;DR: In this article, the authors proposed a method for estimating forest biomass using allometric equations which relate the biomass of individual trees to easily obtainable non-destructive measurements, such as diameter.

TL;DR: In this article, the authors show that paving, recuperate or constructing 6245 km of roads in the Amazon may have the opposite effect of increasing forest fire in the region, and that road paving will accelerate deforestation, logging, forest fire, smoke-related illness, and displacement of small-scale farmers.

TL;DR: In this paper, an unbiased model of the relationship between Db and tree mass was developed using data from 315 trees (5c mDb) harvested in the central Amazon and compared with other theoretical (na 1) and empirical models (na 4).

TL;DR: This paper developed procedures for using Bayesian belief networks (BBNs) to model habitat and population viability of selected at-risk fish and wildlife species, and derived estimates of prior and conditional probabilities from a mix of empirical data and expert judgment, mostly the latter.

TL;DR: In this article, a mechanistic hydro-ecologic explanation for the relationship between stand age and water yield for mountain ash (Eucalyptus regnans ) forested catchments in the Central Highlands of Victoria, Australia was provided.

TL;DR: Long-term changes (20 years) in water yield, the storm hydrograph, stream inorganic chemistry, and sediment yield were analyzed for a 59 ha mixed hardwood covered catchment (Watershed 7) in the southern Appalachian mountains (USA) following clearcutting and cable logging.

TL;DR: Data from the so-called Level II Plots which were established within the frame of the Pan-European Programme for Intensive and Continuos Monitoring of Forest Ecosystems were used to quantify stand structure and species diversity by means of different indices show that there exist only few and weak correlations between species diversity of different vegetation layers, and between plant species diversity and diversity of stand structure, while among all the indices ofStand structure a correlation exists.

TL;DR: This estimate includes all live and dead plant material above- and below-ground with the exception of soil organic matter and propagated errors in sampling and those associated with allometric relations and other ratios used to estimate biomass of roots, lianas and epiphytes, and necromass.

TL;DR: The influence of anthropogenic disturbance on forest structure and composition in the highly populated Montane Rain Forests of northern Chiapas, Mexico was studied, with a high number of understory trees species in QPF, and an impoverished composition in PF.

TL;DR: In this article, the authors compare the current age structure of holm oak Quercus ilex L. dehesas and forests in order to ascertain whether the agroforestry use is hampering the natural regeneration of tree populations and hence the long-term sustainability of Dehesas.

TL;DR: The southern Yucatan peninsular region project as mentioned in this paper aims to unite research in the ecological, social, and remote sensing sciences to provide a firm understanding of the dynamics of deforestation and to work towards spatially explicit assessments and models that can be used to monitor and project forest change under different assumptions.

TL;DR: It is concluded that a whole-plant perspective rather than a leaf-centred view of drought response is needed to predict the consequences of water shortage for ecosystem-level processes, such as tree competition and succession driven by climate change.

TL;DR: In this article, thermal dissipation probes inserted into hydro-active sapwood were used to measure rates of xylem sap flow for six major hardwood species growing in an upland oak forest of east TN.

TL;DR: In this forest, more intensive management maximized species richness, but the lower intensity practices better conserved understory plants typical of late-seral stands, supporting the suggestion that in addition to the total amount of biomass removed, post-harvest practices also affect plant diversity.

TL;DR: In this article, a review of 15 years of research investigating rain forest dynamics of southwest Sri Lanka with the objective of using this knowledge for forest restoration is presented, and six common principles are provided for understanding the integrity of rain forests dynamics in southwest India: (i) disturbances provide the simultaneous initiation and/or release of a new forest stand; (ii) disturbances are generally non-lethal to the ground-story vegetation; (iii) disturbance are variable in severity, type and extent across rain forest topography; (iv) guild diversity (habitat diversity) is dependent

TL;DR: Overall plant diversity was least in the unmanaged stands and progressively increased with intensity of disturbance/stand treatments, while species richness remained stable while abundance of native graminoids increased significantly with treatment intensity through thinned and burned stands.

TL;DR: In this article, the authors measured the litter fall and forest floor in four undisturbed natural forest sites of three coniferous (Pinus pinaster Aiton, Pinus nigra Arn. v. pallaciana, and Abies borisii regis, Matf.), and one deciduous (Fagus silvatica L.) species located in northern Greece.

TL;DR: This study examines the possibility of describing fire spread in shrubland by means of a simple empirical model and found it was not possible to identify individual effects of the fuel-complex descriptors on fire propagation.

TL;DR: It is observed that the natural regeneration of native forest species originating from remnant forests in the general vicinity of the study sites was significantly greater within the direct-seeded plots than in unplanted control plots that were protected from fire and other disturbances.

TL;DR: Investigation of the immediate response of mature boreal spruce forest understorey vegetation to four different felling methods in southern Finland found there were significant differences between the felled areas and residuals in gap felling in post-treatment vegetation species composition and cover.

TL;DR: It is proposed in this review that individual-tree modelling methodologies need to characterise and include structured stochasticity, and benefits from incorporation of stochastics structure include valid statistical inference, improved estimation efficiency, and more realistic and theoretically sound predictions.

TL;DR: Logistic models predicting probability of survival for individual trees were developed, respectively, for Norway spruce, Scots pine, birch, and for other broadleaved trees to have an appropriate level of reliability in large scale forestry scenario models for even-aged and uneven-aged forests.

TL;DR: The authors conducted a large-scale, cross-sectional survey of 30- to 70-year-old coniferous forests in western Washington to determine if previously reported relationships would hold with an unrelated, larger sample.

TL;DR: In this article, the relationship between logging intensity and changes in ground cover vegetation was studied in 16 species and groups of species recorded at 10- or 11-year intervals in mature conifer-dominated forests.

TL;DR: In this article, the problem of converting conifer high forest plantations to irregular stands is addressed using natural regeneration, except where other species or genotypes are desired, where the start of transformation must await adequate seed production which will probably not occur before 30 years of age.

TL;DR: Invertebrates that lived deeper in soil suffered lesser mortality than those in the vegetation and litter layers did, and greater mobility in soil (Staphylinidae) or a thick cuticle (Oribatediae, Elateridae) may have contributed to the higher survival observed in these taxa.

TL;DR: Results are a map series of fire history during 21 years as well as a map of the fire recurrence level and a first approach to monitor post-burn regeneration through normalised difference vegetation index.

TL;DR: The structure and composition of the overstory, understory, and soils are described, 30 years after their first examination, suggesting that inferences made via overstory–understory relations in regards to forest succession are relatively robust over this time period.
