Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane

open access: yesJournal of Polymer Science, EarlyView.
Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...

Multiple barriers maintain species boundaries in sympatric brood‐site deceptive Gastrodia orchids

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Gastrodia orchids are inconspicuous forest plants that lack chlorophyll and obtain carbon from fungi. Their dull‐colored, ground‐level flowers are often hidden among leaf litter, yet they rely on small flies for pollination.

A composite, host‐participatory haustorium links host compatibility to defence bifurcation in Alectra vogelii (Orobanchaceae)

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Parasitic weeds of the family Orobanchaceae are among the most damaging constraints on food production in the tropics, draining water and nutrients from their hosts and threatening the livelihoods of millions of smallholder farmers. Yellow witchweed (Alectra vogelii) can destroy entire legume harvests across sub‐Saharan Africa, where these crops are a ...

The functional role of ants in no‐till cropping systems

open access: yesPest Management Science, EarlyView.
Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.

Early warning signals of common vole population growth in continental Mediterranean farmlands recurrently affected by outbreaks

open access: yesPest Management Science, EarlyView.
Rodent outbreaks have significant socio‐economic impacts worldwide, and anticipation is crucial for timely management decisions. We combined rainfall and periodicity data to provide an early warning signal of vole population growth in Mediterranean farmlands, a year in advance of a peak.
