Health status of forest stands on permanent research plots in the Krkonoše Mts.

open access: yesJournal 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 ...

Simulated impacts of insect defoliation on forest carbon dynamics

open access: yesEnvironmental Research Letters, 2012
Many temperate and boreal forests are subject to insect epidemics. In the eastern US, over 41 million meters squared of tree basal area are thought to be at risk of gypsy moth defoliation. However, the decadal-to-century scale implications of defoliation

An Experimental Comparison of Two Methods on Photosynthesis Driving Soil Respiration: Girdling and Defoliation.

open access: yesPLoS ONE, 2015
Previous studies with different experimental methods have demonstrated that photosynthesis significantly influences soil respiration (RS). To compare the experimental results of different methods, RS after girdling and defoliation was measured in five ...

Effects of Defoliation Timing and Intensity on Yield Components and Grain Quality of Quinoa (Chenopodium quinoa Willd.)

open access: yesPlants
Understanding plant tolerance to defoliation is crucial for sustainable pest management and reducing pesticide use in food production. This study explores quinoa’s (Chenopodium quinoa Willd.) responses to foliar damage, which have been largely unexamined.

Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical 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.

Transcriptome differential expression analysis of defoliation of two different lemon varieties [PDF]

open access: yesPeerJ
‘Allen Eureka’ is a bud variety of Eureka lemon with excellent fruiting traits. However, it suffers from severe winter defoliation that leads to a large loss of organic nutrients and seriously affects the tree’s growth and development as well as the ...
