Simulated beetle defoliation on willow genotypes in mixture and monotype plantations

open access: yes, 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.

Utilising leaf number as an indicator for defoliation to restrict stem growth in rhodes grass (Chloris gayana) cv. Callide [PDF]

open access: yes, 2009
A plot experiment examined the yield response of a nitrogen-fertilised rhodes grass (Chloris gayana) sward to defoliation using the production of a set number of leaves after the last defoliation as the indication for defoliation harvesting. Two factors,

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.

Quantifying the interactions between defoliation interval, defoliation intensity and nitrogen fertiliser application on the nutritive value of rainfed and irrigated perennial ryegrass

open access: yes, 2017
A key goal of temperate pasture management is to optimise nutritive value and production. The influence of individual components such as irrigation, nitrogen (N) fertiliser, and grazing interval and intensity has been well researched, yet conjecture ...

Physiology of Cotton Defoliation

open access: yes, 2015
Revised 06/2015. Originally published 07/2001.3 pp.This bulletin deals with the physiology of cotton defoliation and attempts to describe what conditions must exist inside the plant in order for defoliation to occur.

Regrowth dynamics and morpho-physiological characteristics of Plantago lanceolata under different defoliation frequencies and intensities [PDF]

open access: yes
Traditional pastures in temperate regions face limitations such as reduced growth and nutritional quality during the summer season. Plantain (P. lanceolata L.) offers advantages like increased yield and decreased nitrogen losses from grazing ruminants ...

Herbage accumulation, morphological composition, and nutritive value of Paspalum notatum CV. INIA Sepé

open access: yesAgrociencia Uruguay, 2021
Defoliation strategies determine sward canopy structure and affect forage accumulation and nutritive value. The objective of this study was to determine forage accumulation, morphological composition and nutritive value of inia Sepé subjected to ...

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

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.
