Environmental Toxicology, EarlyView.ABSTRACT The increased use of agrochemicals to enhance crop production has had detrimental environmental effects including implication in the sharp decline of North American farmland‐breeding birds. Here, using a combination of deep shotgun metatranscriptomics and pesticide exposure data, we sought to assess whether exposure to cotton (Gossypium spp ...

Bromus-Poa response to defoliation intensity and frequency under three soil moisture levels
, 2002 Smooth brome (Bromus inermis Leyss.) and Kentucky bluegrass (Poa pratensis L.) are important herbage for livestock and wildlife in Aspen-Boreal ecosystems in central Alberta, but there is paucity of information on the relationship between soil moisture ...

The relative abundance of crop and natural food influences crop consumption by brown bears
Wildlife Biology, EarlyView.Many mammalian species now inhabit anthropogenic landscapes, and human–wildlife conflicts, particularly pertaining to crop damage, have become a significant issue. To develop more effective measures to limit crop damage caused by wildlife, it is crucial to identify how natural and anthropogenic food availability affect crop use by wildlife in the ...

IET Smart Energy Systems, EarlyView.This paper proposes a two‐stage electric agricultural machinery charging optimisation strategy that first adjusts Charging scheduling to minimise load variance, then uses V2G technology with idle machinery as energy storage to reduce fluctuation and improve PV integration, solved via NSGA‐II and TOPSIS.

Effect of defoliation on patterns of carbon exudation from Agrostis capillaris
, 2004 Grassland ecosystems are important global sinks and sources of atmospheric carbon (C). In this study, we used an in-situ 13CO2 tracer approach to quantify differences in short-term C exudation from defoliated and non-defoliated Agrostis capillaris (L ...

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.

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.

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 ...

Goose herbivory alters soil microbial community functional potential in a sub‐Arctic wetland
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivory alters below‐ground resource dynamics via direct and indirect mechanisms, yet its effects on microbial functional potential remain poorly understood. This limits our understanding of the mechanisms that link animal, plant and microbial functional roles in ...

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 ...
