Restoration ecology in conflict along the Colorado front range

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Cheatgrass (Bromus tectorum) is a challenge to restoration in western North America. It attracts the attention of academic and government research scientists, weed managers, and chemical companies. Attempts to control it cause conflicts among these groups.

Use of the imazapic herbicide applied alone or tank mix with imazapyr as growth regulator of lawns

open access: yesBioscience Journal, 2021
Successive mowing are the major maintenance costs of lawns. Thus, both the expenditure with mowing and the visual and physiological aspect of the lawn have led to the search for alternatives to mechanical management.

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

open access: yesPest Management Science, Volume 82, Issue 7, Page 5987-6009, July 2026.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Summary of Toxicity Studies on Imazapyr

open access: yesJournal of Pesticide Science, 1997
イマザピルはアメリンカン・サイアナミッド社が開発した多年生及び一年生雑草を対象とする非農耕地用の非選択性除草剤である. またそのユニークな作用特性により1%液剤は多年生雑草を対象とした抑草剤として開発に成功した. イマザピルは各種毒性試験の結果, きわめて安全性の高い薬剤であることが示された. 急性毒性は非常に弱く普通物に相当した. 変異原性, 催奇形性は認められず, 顕著な薬理作用も認められなかった. 眼に対する刺激性, 皮膚に対する弱い刺激性はみられたが, 皮膚感作性は陰性であった. ラットを用いた亜急性毒性試験では, 高用量群 (10,000ppm) の雄ラットで一時的に体重増加抑制, 食餌効率の低下がみられたのみで非常に毒性が低かった.

Management of invasive alien plants in forests: A global perspective

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
This review exposes urgent and critical knowledge gaps in forest IAP management, which need addressing to meet global targets for biodiversity and forest health. These gaps include highly uneven global research effort, narrow species focus, limited method replication, overlooked seasonal effects, and inconsistent cost reporting.

Community perceptions and management of the fleshy‐fruited invasive alien plant Pyracantha angustifolia: Insights from South Africa's Montane grasslands

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1869-1879, June 2026.
Abstract Invasive alien plants can provide economic or cultural benefits to local communities, influencing perceptions and potentially affecting management decisions. Understanding these perceptions is crucial to avoiding inefficiencies, misunderstandings and conflicts in the management of invasive alien species.
