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 ...

Response of Bromus valdivianus (Pasture Brome) Growth and Physiology to Defoliation Frequency Based on Leaf Stage Development

Agronomy, 2021
The increase in drought events due to climate change have enhanced the relevance of species with greater tolerance or avoidance traits to water restriction periods, such as Bromus valdivianus Phil. (B. valdivianus). In southern Chile, B.

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.

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 ...

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 ...

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.

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

A Self-Calibrated Non-Parametric Time Series Analysis Approach for Assessing Insect Defoliation of Broad-Leaved Deciduous Nothofagus pumilio Forests

Remote Sensing, 2019
Folivorous insects cause some of the most ecologically and economically important disturbances in forests worldwide. For this reason, several approaches have been developed to exploit the temporal richness of available satellite time series data to ...

Defoliation frequency outweighs timing as a driver of tree mortality related to drought-defoliation interaction

Climate change is expected to increase the frequency and severity of forest disturbance, making it more likely that multiple forms of disturbance will occur simultaneously.
