Fruit quality and production of Vitis vinifera L. Chardonnay affected by partial defoliation in tropical highlands [PDF]

, 2015
Using a completely randomized design with twotreatments (50% defoliation and a control without defoliation)and six replications per treatment, the fruit quality and productionof grape plants subjected to early partial-defoliation in Villa deLeyva ...

A rationally designed peptide targeting trypsin‐like enzymes impairs feeding and redox homeostasis in Anticarsia gemmatalis (Lepidoptera: Erebidae)

Pest Management Science, EarlyView.
GORE3 interacts with digestive proteases in Anticarsia gemmatalis, promoting digestive inhibition, oxidative stress, and midgut cell damage. These physiological disturbances diminish larval survival and feeding damage on soybean plants, emphasizing the potential of GORE3 as a bioinsecticidal peptide for pest control.

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.

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 ...

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 ...

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 ...

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.

Herbivore versus detritivore effect on decomposition through leaf conversion into faeces

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In terrestrial ecosystems, plant residues can reach the soil as senesced leaf litter or green leaves, and both types can be transformed by invertebrates into detritivore or herbivore faeces.

The impacts of large wild grazers on soil carbon persistence are strongly modulated by the environmental context

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Wild animals, particularly large mammalian grazers, can influence ecosystem carbon dynamics and soil carbon sequestration. However, we lack a mechanistic understanding of how wild grazer communities influence soil carbon persistence, specifically in terms of the size of

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 ...
