Degree of insecticide exposure and access to nectar impact survival of Trissolcus japonicus, a hymenopteran parasitoid, in flowering border strips

open access: yesAgricultural and Forest Entomology, EarlyView.
We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,

Dietary anthocyanidin pelargonidin activates G protein‐coupled receptor 35

open access: yesThe FEBS Journal, EarlyView.
Pelargonidin, a red‐fruit‐derived anthocyanidin, was newly identified as a dietary agonist of GPR35, a metabolite‐sensing GPCR implicated in anti‐inflammation. Through screening of dietary compounds, pelargonidin emerged as a potent GPR35 agonist, attenuating inflammation in human intestinal cells.

The Outcome of Intracellular Selenomonas sputigena and its Impact on Gingival Keratinocytes

open access: yesMolecular Oral Microbiology, EarlyView.
ABSTRACT Selenomonas sputigena is an understudied oral pathobiont associated with periodontitis and dental caries. We recently demonstrated that S. sputigena binds to gingival epithelial cells (GECs), where afterwards the bacterium causes robust in vitro pro‐inflammatory cytokine production and migration of monocytes and neutrophils.

Engineering Discrete Element Method-Based Design and Optimization of the Key Components of a Spoon-Wheel Spinach Seed-Metering Device

open access: yesAgronomy
In view of issues affecting manual on-demand sowing of spinach, such as high working intensity, low seeding efficiency, and high cost, a mechanized precision seeding device for spinach seeds is proposed, based on a spoon-wheel including a combined cell ...

Trait‐based recovery of insect functional diversity following pine removal in a shrubland biodiversity hotspot

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction A primary goal of habitat restoration is the return of both taxonomic and functional diversity to support ecosystem resilience and functioning. This study assessed how insect functional biodiversity (focusing on beetles [Coleoptera] and ants [Formicidae]) responds to invasive pine (Pinus spp.) removal, in a Mediterranean‐type ...

EXPLAINING THE ADOPTION AND DISADOPTION OF SUSTAINABLE AGRICULTURE: THE CASE OF COVER CROPS IN NORTHERN HONDURAS [PDF]

open access: yes
Although technology adoption has been the subject of a great deal of economic research, that focused on the economics of adoption of low-input "sustainable" systems has been much more limited and recent.

Lawn Weeds in Alaska [PDF]

open access: yes, 1963
Many different kinds of plants usually grow in close association with each other in nature. Woodlands, roadsides, mountain slopes, marshlands-almost all places not closely attended by man have their own complex plant associations.

Estimating costs of ecological restoration across degradation scenarios in South Brazilian grasslands

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Grassland ecosystems are among the most threatened worldwide, and the Campos Sulinos—a region of subtropical grasslands in southern Brazil—experiences degradation driven by multiple factors. This study provides initial cost estimates for different restoration approaches, offering guidance for technical and budgetary planning ...
