Moderately thinning encroaching shrub species is key to balancing rangeland restoration and arthropod biodiversity conservation in Namibia

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Moderate manual thinning (50F) maintained arthropod diversity comparable to untreated controls while reducing shrub dominance, demonstrating that structural heterogeneity buffers biodiversity loss during rangeland restoration in Namibian bush‐encroached systems. These findings advocate mosaic debushing strategies that preserve vegetation complexity and

Scientific Opinion addressing the state of the science on risk assessment of plant protection products for in‐soil organisms

EFSA Journal, Volume 15, Issue 2, February 2017., 2017
Abstract Following a request from EFSA, the Panel on Plant Protection Products and their Residues developed an opinion on the science behind the risk assessment of plant protection products for in‐soil organisms. The current risk assessment scheme is reviewed, taking into account new regulatory frameworks and scientific developments. Proposals are made

Tolerance and sorption of Bromacil and Paraquat by thermophilic cyanobacteria Leptolyngbya 7M from Costa Rican thermal springs

, 2019
We studied the adsorption ability and tolerance of the thermophilic filamentous cyanobacteria Letolyngbya 7M towards Paraquat and Bromacil. Adsorption isotherms at pH = 7.0 showed an adsorption capacity of 24.4 mg/g and 66.8 mg/g, respectively, and a ...

Adjuvant use for the management of pesticide drift, leaching and runoff

Pest Management Science, Volume 80, Issue 10, Page 4819-4827, October 2024.
Review of laboratory and field research/modelling of adjuvant effects on pesticide drift, leaching and runoff. Adjuvants modifying emulsion/extensional viscosity properties of tank mixes can reduce small droplet fractions of sprays, reducing drift potential with some nozzles. Binding adjuvants can reduce leaching.
