Partial defoliation of Brachypodium distachyon plants grown in petri dishes under low light increases P and other nutrient levels concomitantly with transcriptional changes in the roots [PDF]
PeerJ, 2019 Background There have been few studies on the partial defoliation response of grass. It has been unclear how partial defoliation may affect roots at the levels of nutrient accumulation and transcriptional regulation.

The functional role of ants in no‐till cropping systems
Pest Management Science, EarlyView.Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.

Nature, 1922 A REFERENCE to the defoliation of oaks, particularly on the borders of Surrey and Hampshire, by the larvae of Tortrix viridana, was made in NATURE on June 10. It concludes with the remark that the effect of the defoliation is to check “the growth of the trees to some extent for the time being, but is rarely more serious.”

Pest Management Science, EarlyView.Shrimp shell compost suppresses Verticillium dahliae microsclerotia, enhances chitinase activity, lowers olive wilt severity and improves plant recovery under controlled conditions. Abstract BACKGROUND Verticillium wilt of olive (Olea europaea L.), caused by Verticillium dahliae Kleb., is difficult to manage because long‐lived microsclerotia persist in

Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats
Remote Sensing in Ecology and Conservation, EarlyView.Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (

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 ...

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 ...

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 ...
