Typhoons are having an increasingly severe and widespread impact on forest ecosystems around the world due to climate change. However, few studies have examined impacts of strong typhoons subtropical evergreen broadleaved forests, particularly in rare old-growth forests. Here, using a 20 ha permanent plot Guangdong Province, southern China, super Typhoon Mangkhut secondary forests was quantitat...

Alley cropping agroforestry systems are complex agroecosystems highlighted for their positive effects on soil quality. However, the potential spatial heterogeneity of quality created by tree rows at plot scale has seldom been studied. The aim this study was to evaluate scale, under and along transects perpendicular row compare alley with monocropping systems. This performed an system that combi...

Stampfli A. 1992. Effects of mowing and removing litter on reproductive shoot modules of some plant species in abandoned meadows on Monte San Giorgio. Bot. Helv. 102: 85-92. Reproductive shoot modules have been counted in a permanent plot experiment on Monte San Giorgio (Southern Switzerland) since 1988. The 8 species presented here, including the dominant grass (Molinia arundinacea) and seven ...

Holographic interferometry has been used to plot graphs of the phototropic and geotropic bending undergone by a mature Stapelia variegata Linn over a 5-minute period. The holographic interferometric technique is shown to have the advantage of measuring displacements at least as small as 0.16 micrometers which permits observation of extremely slow plant motions over time periods of a few minutes...

Permanent forest plots (PSP) were used to investigate long-term basal-area tree growth rates across the boreal forests in Canada. The objectives were to discern whether or not these rates i) are similar across the boreal zone and ii) correlate to change in climate from 1970 to 2010. The results show that rates vary by region, with decreasing growth rates for about 60% of individual trees in wes...

Concerns about the efficiency and the reliability of point sampling to estimate change in forest growth variables have been expressed ever since point sampling appeared in the literature more than 60 years ago. Change estimators for point samples based on point-to-tree distance in variable-radius plots were introduced about 30 years ago but are rarely implemented despite easy access to point-to...
