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

Herbage utilisation efficiency of continuously stocked pastures during periods of restricted pasture growth

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2020
The aim of this study was to evaluate the defoliation patterns of individual tillers, efficiency of herbage utilisation, and forage production in continuously stocked Brachiaria humidicola cv. Comum swards during periods of the year of restricted pasture

Grass defoliation intensity, frequency, and season effects on spotted knapweed invasion

, 1999
Preventing the invasion of uninfested rangeland is central to managing spotted knapweed (Centaurea maculosa Lam.). Intensity, frequency, and season of grass defoliation determine the ability of grasses to tolerate grazing and resist weed invasion.

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 ...

Effect of defoliation interval and height on the growth and quality of Arachis pintoi cv. Amarillo [PDF]

, 2007
The effect of defoliation on Amarillo (Arachis pintoi cv. Amarillo) was studied in a glasshouse and in mixed swards with 2 tropical grasses. In the glasshouse, Amarillo plants grown in pots were subjected to a 30/20°C or 25/15°C temperature regime and to

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 ...
