Critical impact of defoliation on garlic yield during key developmental stages [PDF]

Pesquisa Agropecuária Brasileira
The objective of this work was to evaluate the effect of defoliation levels at different growth stages of garlic plants on total and marketable yields. The experiments were conducted during two crop seasons, when five dates (30, 60, 90, 110, and 130 days

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 ...

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 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 ...

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.

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 ...

The Coloniality of Data: Police Databases and the Rationalization of Surveillance from Colonial Vietnam to the Modern Carceral State

The British Journal of Sociology, EarlyView.
ABSTRACT Tracing the early adoption of computer gang databases by the Los Angeles County Sheriff's Department and the Los Angeles Police Department in the 1980s to the deployment of computationally‐assisted surveillance during the Vietnam War, this paper uses a genealogical approach to compare surveillance technologies developed across the arc of ...

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.
