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.

Controlled incubation, leachate, and pot assays of shrimp shell‐based compost for suppressing Verticillium dahliae in olive

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 (

Cotton Farming Pesticides Affect Ileal Microbiota Activity and Expression of Virulome but Not Resistome or Metabolic Pathways in a Sedentary Wild Passerine

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 ...

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.

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 ...

Concentration of Potassium, Magnesium, and Iron of Brachiaria humidicola (Rendle Schweick) at Various Cultivation Methods and Defoliation Intervals

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 ...

Forest defoliation scenarios

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 ...

A Collaborative Optimisation Strategy of Electric Agricultural Machinery Clusters and Rural Distribution Network in Renewable Energy Storage Application Scenario

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.
