Field‐based evidence of impaired sperm quality associated with conventional farming in two passerine birds

Ibis, EarlyView.
The detrimental effects of conventional farming on bird biodiversity are increasingly documented. Despite this, the specific impacts of both organic and conventional farming practices on bird coloration and sperm quality in natural settings remain unexplored. This study aimed to determine whether these farming practices differentially affect body mass,

A natural variation within duplicated AsWRKY49‐D2 drives the subgenomic functional divergence of homeologs in salt response of allohexaploid oats

Journal of Integrative Plant Biology, EarlyView.
Transcriptome analysis of oats under salt stress identified ten important salt‐responsive transcription factor families, which show extensive functional divergence among three oat subgenomes. Further integration with a genome‐wide association study under salt stress identified the AsWRKY49‐D2 gene, whose elite haplotype holds substantial potential for ...

The Capital–Labour–State Dynamics of Herbicide Adoption in Rainfed India

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper engages debates around the capital–labour–state dynamics of agrarian transitions to address the oft‐studied but still little‐understood question of why farmers adopt herbicides when they do. Over the last several years, smallholder farmers in India have begun using the herbicide bispyribac sodium at breakneck speeds, particularly in

Things at Work: How Things Contribute to Performing Work

Journal of Management Studies, EarlyView.
Abstract A crucial question for organizations is what constitutes work performance. While the importance of human competence and motivation to work performance has been established, less well understood is how ‘things’ – such as algorithms, tools, instruments, and raw materials – contribute to work performance.
