The Potential of Arable Weeds to Reverse Invertebrate Declines and Associated Ecosystem Services in Cereal Crops [PDF]

open access: yes, 2020
There is global concern that invertebrate populations are declining rapidly, particularly in agricultural habitats. Declines have been attributed to the intensification of farming systems, with many studies focussing on a lack of semi-natural habitat in ...

Evaluating the allelopathic potentiality of seed powder of two Brassicaceae plants in controlling Orobanche ramosa parasitizing Lycopersicon esculentum Mill. plants

open access: yesBulletin of the National Research Centre, 2019
Background Orobanche ramosa (Broomrape) is an obligate root parasite belonging to Orobanchaceae. It causes a great damage to tomato plants. Several attempts have been done in order to control this parasitic weed.

Cytogeography of Naturalized Solidago canadensis Populations in Europe

open access: yesPlants, 2023
Autopolyploidization has driven the successful invasion of Solidago canadensis in East Asia. However, it was believed that only diploid S. canadensis invaded Europe, whereas polyploids never did.

Entropic optimal transport is maximum-likelihood deconvolution [PDF]

open access: yes, 2018
We give a statistical interpretation of entropic optimal transport by showing that performing maximum-likelihood estimation for Gaussian deconvolution corresponds to calculating a projection with respect to the entropic optimal transport distance.

A metaphor for epidemiology: The sea of person time

open access: yesGlobal Epidemiology, 2021
Metaphors have had an important role to play in the theory and practice of epidemiology. Some well-known examples include “black boxes,” the “web of causation,” “shoe-leather epidemiology,” the “ivory tower” and the ubiquitous “gold standard.” Metaphors ...

Commentary: On the reliability of causal claims

open access: yesGlobal Epidemiology, 2022
Causal assessments in epidemiology are a complex process due to the many methods involved. The general scientific method lords over the process joined by study designs and statistical methods.

The dual allelopathic capacity of two Brassicaceae plants’ seed powder in controlling Orobanche crenata infesting Pisum sativum as well as stimulating its growth and yield

open access: yesBulletin of the National Research Centre, 2020
Background It is well known that legume and other crops such as pea, faba bean, lentil, chick pea, and several other crops are susceptible to Orobanche crenata (broomrape) infestation. There is a direct relationship between O.

Long−Distance Wind Dispersal Drives Population Range Expansion of Solidago canadensis

open access: yesPlants, 2022
Canada goldenrod (Solidago canadensis L.) is a serious invasive alien plant species that exerts negative effects on natural and agricultural ecosystems in China. Few studies have addressed the dispersal of S.

Laser weeding of common weed species [PDF]

open access: yesFrontiers in Plant Science
The massive use of herbicides since the 1950s has resulted in increasing problems with herbicideresistant weeds and pollution of the environment, including food, feed, and water. These side effects have resulted in political pressures to reduce herbicide application.

Evaluating Sensor-Based Mechanical Weeding Combined with Pre- and Post-Emergence Herbicides for Integrated Weed Management in Cereals

open access: yesAgronomy, 2022
Due to the increasing number of herbicide-resistant weed populations and the resulting yield losses, weed control must be given high priority to ensure food security.
