Mathematical Biosciences and Engineering, 2007 We consider the mathematical model originally created by Ludwig, Jones, and Holling to model the infestation of spruce forests in New Brunswick by the spruce budworm. With biologically plausible parameter values, the dimensionless version of the model contains small parameters derived from the time scales of the state variables and smaller parameters ...

Lotus tenuis and Schedonorus arundinaceus co-culture exposed to defoliation and water stress
Revista de la Facultad de Ciencias Agrarias, 2021 The present study aimed to investigate the effect of defoliation frequency (low and high) and water stress (excess or deficit) on biomass production, P and N nutrition, and symbiosis with native soil microorganisms on a Lotus tenuis and Schedonorus ...

Interactive effect of herbivory and competition on the invasive plant Mikania micrantha. [PDF]
PLoS ONE, 2013 A considerable number of host-specific biological control agents fail to control invasive plants in the field, and exploring the mechanism underlying this phenomenon is important and helpful for the management of invasive plants.

Animal Production: Indonesian Journal of Animal Production, 2006 The existence of weeds significantly decreases the rate of production and quality of herbage. Physical weed control by defoliation could be expected to sustain quality and production of herbage, and is able to control weeds expansion.

Patterns and Drivers of Pine Processionary Moth Defoliation in Mediterranean Mountain Forests
Frontiers in Ecology and Evolution, 2019 Insect defoliations are one of the threats of forests health, and climate warming may enhance the occurrence of more severe outbreaks. Thus, understanding the spatial and temporal patterns of insect defoliation may provide valuable information to infer ...

Defoliation percentage in two soybean cultivars at different growth stages
Revista Brasileira de Engenharia Agrícola e Ambiental, 2015 The objective of this study was to evaluate the agronomic variables due to the effects of different levels of defoliation in the phenological phases of two soybean cultivars. The experiment was conducted during the 2011/2012 season, in a randomized block
