TL;DR: In the mixed conifer‐hardwood forests around the Great Lakes in North America, widespread habitat modification and the extirpation of native predators and other ungulates have acted to boost populations of white-tailed deer to historically high densities, as evidenced by demographic analysis.

TL;DR: The annual rate of change of forest cover should be calculated as: r =(1/( t 2 − t 1 ))×ln( A 2 / A 1 ).

TL;DR: In this paper, the accuracy and reliability of the biomass expansion factors (BEFs) were improved by applying these age-dependent BEFs, which are formulated on the basis of representative data and which include an estimate of uncertainty.

TL;DR: In order to contribute to a better understanding of the impact of air pollution and other environmental factors on forest ecosystems, a Pan-European Programme for Intensive and Continuous Monitoring of Forest Ecosystems has been implemented in 1994 as discussed by the authors.

TL;DR: In this article, the authors present a narrative that portrays conditions beginning at the first contact of Euro-American settlers with Indoamericans of the region and extending to the present, highlighting key changes to forest landscape patterns and processes that occurred under these combined influences, discuss implications of the changes, and progress towards restoring sustainability.

TL;DR: In this article, the authors investigated the sensitivity and resistance of Common beech (Fagus sylvatica L.) stands to current environmental changes and found that at higher altitudes in Central Europe, environmental changes in the recent past with negative effects on cambial activity are the predominant growth influences.

TL;DR: In this paper, the authors studied young riparian cottonwoods and associated woody plants along Soda Butte Creek and the Lamar River in northeastern Yellowstone National Park (YNP) to examine the potential influence of wolf/elk interactions upon plant growth.

TL;DR: A strong influence of number of species per individual on b-diversity suggests that for resisting change in floristics due to disturbance, a site must have low species-individual ratio.

TL;DR: The objective of this paper is to provide a general overview of the influence of wildland fires on the erosional processes common to the forested landscapes of the western United States.

TL;DR: In this article, a network of lake records of the Pacific Northwest and summer-dry regions of the northern Rocky Mountains of the US was used to assess the nature of future fire-climate-vegetation linkages in the region.

TL;DR: The authors examined aspects of forest composition and structure thought to be important to wildlife along a tropical moist forest chronosequence in the Barro Colorado Nature Monument (BCNM) of central Panama.

TL;DR: For the three tree species and one shrub, resprouting individuals did not reach the minimum reproductive size within 1 year of burning, while the other shrub and the two subshrubs were able to reach reproductive size during this time, indicating that growth form largely determines the population response to frequent burning.

TL;DR: In this paper, the authors examined the influence of natural disturbances in presettlement and modern times on the age distribution of forest stands based on the assumption of a random spatial pattern of disturbance.

TL;DR: In this paper, the accuracy of forest stand type maps derived from a Landsat Thematic Mapper (Landsat TM) image of a heterogeneous forest covering rugged terrain is generally low.

TL;DR: In this article, an assessment on key ecological factors affecting runoff and soil erosion and the usefulness of plot-level monitoring of soil erosion was conducted by collecting runoff data from 14 runoff plots.

TL;DR: In this paper, the influence of fertilization on belowground processes such as soil respiration, fine root biomass production, and microbial biomass along a fertilization gradient was measured in 7-year-old cottonwood and loblolly pine plantations, established on a well-drained, siliceous, thermic Rhodic Paleudlt, in northwest Florida.

TL;DR: In this paper, the authors exhaustively review the evidence regarding the viability and desirability of sustainable forest management in the tropics and reject the claim that sustainable timber management generally damages forests more than conventional logging.

TL;DR: In this article, the 3-PG model is used to predict stand growth in areas where trees have not been grown, i.e. the model can be used to estimate site productivity.

TL;DR: In this article, the behavior, properties, and influence of natural fire in riparian areas of the western USA was investigated, and it was shown that cumulative impacts of human alterations are likely to exert the most pronounced influence on fire behavior during periods of drought and under conditions of extreme fire weather.

TL;DR: In this paper, the seasonal dynamics of soil phosphorus and associated microbial properties were investigated in upper (0-5 cm) soils under adjacent unimproved grassland and a 19-year-old forest stand (mixture of Pinus ponderosa and Pinus nigra).

TL;DR: In this paper, the authors present the hydrological results from 28 basins across Europe sampling a wide range of forest types, climate conditions and ground conditions, and determine if forestry can have significant impacts on stream flows and to identify particularly critical situations.

TL;DR: A quantitative framework is developed for analyzing the mass budget of in-stream woody debris and the relationships among process rates, their spatial variance across landscapes, and the resulting probability distributions of long-term patterns of wood abundance are proposed as a set of general theoretical principles.

TL;DR: In this article, the types and amounts of early successional habitats created depend on the silvicultural system used, patch size selected, time between regeneration cuts, and rotation age.

TL;DR: In this paper, the authors presented an analysis of forest spatial structure and diversity in the Federal State of Durango where the majority of the forests consist of pure pine stands or pine mixed with oak.

TL;DR: In this paper, the authors explored the richness of saproxylic beetles, composition of species assemblages and relationship between SA beetles and their substrate in managed and seminatural pine dominated forests.

TL;DR: This study suggests that the regeneration of Q. pyrenaica forests in Mediterranean mountains can be limited by herbivores acting at several life-history stages, both acorn and seedling survival were much lower in the shrublands than in the forests.

TL;DR: A soft methodology is presented, called cognitive mapping, which can be used to assess the cross-indicator interaction, linkages, and connectivities of the indicators, and attempts to evaluate the overall cumulative impacts of all indicators as they impact sustainability directly and indirectly through their interactions with other indicators.

TL;DR: In this article, the responses of stream benthic macroinvertebrates to fire in western United States indicate a consistent pattern of response that can guide resource management and future research.

TL;DR: Root phenology and ontogeny are depicted, and the biological responses of the roots to adverse growing conditions appraised, illustrating that root parameters are good indicators of the sustainability of forest sites.

TL;DR: Yellow-poplar displayed greater response to periodic droughts at the southwest aspect while the oaks showed little evidence of an aspect-related interaction with drought response, which are logical in terms of the ecological strategies of the species.
