The continuing significance of chiral agrochemicals
Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Capturing Crows for the Protection of Threatened and Endangered Shorebird Species
Wildlife Society Bulletin, 2018 Corvids are highly intelligent and capable of thriving in anthropogenic ecosystems. American crows (Corvus brachyrhynchos) regularly depredate threatened and endangered avian species.

How New Caledonian crows solve novel foraging problems and what it means for cumulative culture. [PDF]
, 2015 New Caledonian crows make and use tools, and tool types vary over geographic landscapes. Social learning may explain the variation in tool design, but it is unknown to what degree social learning accounts for the maintenance of these designs.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Fifteen size‐resolved aerosol samples collected during marine fog, with adjacent ambient observations, show that coarse sea salt aerosol is rapidly grown and lost in the northwest North Atlantic Ocean except when subject to extreme winds. The persistence of fog in the absence of sea salt is determined by available fine‐mode aerosol, where greater ...

River Research and Applications, EarlyView.ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

Habitat selection and reproduction of red-backed shrikes (Lanius collurio) in relation to abundance of potential avian nest predators [PDF]
, 2010 Many studies of farmland bird species have related abundance of species to different habitat variables, whereas few studies have incorporated the effects of predation on habitat selection. However, it is generally assumed that prey species select habitat

Big Bird: A global dataset of birds in drone imagery annotated to species level
Remote Sensing in Ecology and Conservation, EarlyView.Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds
