Health status of forest stands on permanent research plots in the Krkonoše Mts.
Journal of Forest Science, 2010 Damage to beech, mixed (beech with spruce to spruce with beech) and spruce stands in the Krkonoše Mts. is described on the basis of evaluation of transition matrices describing the probability of a change in the assessment of defoliation of particular ...

Tree canopy defoliation can reveal growth decline in mid-latitude temperate forests
Ecological Indicators, 2021 Climate and weather fluctuations and changes are the most important environmental drivers of tree canopy defoliation, an indicator of forest health. We examined the relationship between tree defoliation and Basal Area Increment (BAI), a dimension of tree

Effects of time and intensity of defoliation on yield and yield components of corn
پژوهشهای زراعی ایران, 2009 In order to evaluate the effects of time (20, 40, 60 and 100 days after sowing) and intensity of defoliation (0, 33, 66 and 100%) on a corn cultivar ( three way cross 647), a complete randomized block design with split plot arrangement and three ...

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Simulated beetle defoliation on willow genotypes in mixture and monotype plantations
, 2006 The effect of simulated beetle damage (0%, 25%, 50% and 75% mechanical defoliation) on 12 willow genotypes, grown in short-rotation coppice, was studied in a modified criss-cross experimental design.
