Development and change in forest communities are strongly influenced by plant-soil interactions. The primary objective of this paper was to identify how forest soil characteristics vary along gradients of forest community composition in aspen-conifer forests to better understand the relationship between forest vegetation characteristics and soil processes. The study was conducted on the Fishlak...

Surface lignite coal mines in east Texas are commonly reforested using loblolly pine (Pinus taeda L.) following mining and reclamation activities. Due to the nature of such an extreme disturbance, altered growth patterns, growth rates, and productivity could be expected. We destructively sampled aboveand belowground tissue to develop prediction equations specific to these sites. These predictio...

mental evidence obtained by a 5-year experiment with harvesting in a cornfield takes centuries to obtain from a forest. Most foresters have careers that last only 30–40 years. Changes may be occurring in productivity too slowly to be detected by any one generation of foresters. Periodic comparison of long-term controls and harvested forests can show unequivocally whether forest management activ...

Abstract In temperate Europe, oak-dominated forests are widespread, supporting high biodiversity and providing important ecosystem services. Insufficient natural regeneration has, however, been a concern for over century. The objective of this study was to gain insights into differences in success using artificial techniques reforestation oak ( Quercus robur L.) stands. We monitored seedlings f...

On the way to building smart factories as vision of Industry 4.0, casting process stands out a specific manufacturing due its diversity and complexity. One segments foundry design is application artificial intelligence in improvement process. This paper presents an overview conducted research studies, which deal with In review, 37 studies were analyzed over last 15 years, clear indication type ...

Another experiment was carried out in which the opposite environmental conditions were obtained, viz., those of waterlogging. In this a comparison was made between applying Ceresan on the cutting and on the soil. Co.290 was planted, and after planting, 11 inches of rain fell in 18 days; the field was under water for some considerable time. In a previous paperreference was made to the beneficial...

Statistical models explaining students' ratings of photographs of withinstand forest scenes were constructed for 99 forest inventory plots in east Texas pine and oak-pine forest types. Models with parameters that are sensitive to visual preference yet compatible with forest management and timber inventories are presented. The models suggest that the density of sawtimber-sized trees and the prop...

A method for extracting forest parameters is described in this paper. The 3D point clouds derived from phase difference laser scanners in forests were processed in a step-wise separation. The first step contains basic filter methods to reduce raw data which, separates isolated points or deletes those artefacts resulting from the ambiguity problem. The next step includes using algorithms to isol...

Edwards et al. 1 revisited well-known studies reporting power-laws in the frequency distribution of flight duration of wandering albatrosses 2,3 , and concluded that no Lévy process 4,5 could model recent observations with higher resolution. Here we show that this re-analysis 1 suffers from a conceptual misunderstanding, and that the new albatross data remain consistent with a biological Lévy f...
