Faunistic analysis of pest insects and their natural enemies associated with hairy fleabane in soybean crop

open access: yesPesquisa Agropecuária Tropical, 2017
In addition to competing with crops, weeds can provide shelter for arthropods in cropping fields and adjacent areas. This study aimed to investigate the occurrence and population fluctuation of insect pests and their natural enemies associated with hairy

Divergent drought responses in two cold desert shrublands

open access: yesEcosphere, Volume 16, Issue 3, March 2025.
Abstract The frequency and intensity of extreme droughts are projected to increase in the future, yet current research indicates that ecosystem sensitivity to extremes will vary. Despite hundreds of observational and experimental drought studies across ecosystems, the underlying mechanism explaining the inconsistent responses to drought remains poorly ...

High sensitivity of herbaceous legumes to freezing: Insights from a multiyear snow removal study

open access: yesEcosphere, Volume 16, Issue 3, March 2025.
Abstract Reductions in snow cover resulting from winter climate change are anticipated to increase the intensity of freezing exposure for overwintering herbaceous plants in many northern temperate regions. We examined whether herbaceous legumes, a key functional group responsible for increasing soil nitrogen inputs, are more sensitive to freezing than ...

Perennial summer pasture options in Tablelands environments where drought and soil acidity jeopardise pasture persistence

open access: yesGrassland Research, Volume 4, Issue 1, Page 15-30, March 2025.
In temperate, uniform rainfall environments, lucerne is the most reliably productive summer pasture option if soil conditions allow its growth. Chicory is a potential alternative to acidic soils. Good productivity combined with acid soil tolerance favours cocksfoot over tall fescue.

Wild Bee Assemblages and Pollination Networks of Managed Emergent Wetlands in Central New York, USA

open access: yesEcology and Evolution, Volume 15, Issue 2, February 2025.
Wetlands are underrepresented in wild bee surveys yet we find they host a diversity of bee species and offer important late‐season floral resources. Wetland restoration and management for wildlife in the northeastern United States creates a matrix of freshwater wetland habitat that helps support the landscape's wild bee fauna.

Phytochemical analysis and antimicrobial activity of the extract of leaves of fleabane (Conyza sumatrensis)

open access: yesJournal of Applied Sciences and Environmental Management, 2010
Phytochemical analysis of the extracts from the leaves of the plant fleabane (Conyza sumatrensis) revealed the presence of some substances such as tannins, flavonoids, saponins, steroids and glycosides. The presence of these substances is an indicator of

A habitat suitability model for testing and refining the range of Zuni fleabane, a threatened plant species

open access: yesEndangered Species Research
Land managers and conservation practitioners need practical tools to protect rare species in light of rapidly changing climate and land use patterns. Habitat suitability models are tools that can inform multiple-use land management decisions and target ...

Differential susceptibility and resistance to glyphosate in annual ryegrass and wavy-leaved fleabane [PDF]

open access: yesCommunications in Plant Sciences, 2014
Annual ryegrass (Lolium multiflorum) and wavy-leaved fleabane (Conyza bonariensis) were tested, aiming to investigate the dose-response of biotypes of both species to glyphosate. Glyphosate herbicide at doses varying from 0 up to 1.440 g e.a.
