Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity
PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1345-1356, July 2026.The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Toxicity of aqueous extracts of Ilex paraguariensis A.St.‐Hil. about Euphorbia heterophylla L.
Pest Management Science, Volume 82, Issue 7, Page 6196-6206, July 2026.Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.

Time‐ and cultivar‐dependent biochemical responses to heat priming and stress in rice
Annals of Applied Biology, Volume 189, Issue 1, July 2026.Global warming increasingly threatens rice productivity, and understanding the biochemical mechanisms underlying heat stress responses is crucial for developing resilient cultivars. By demonstrating that stress responses are both cultivar‐ and time‐of‐day‐dependent, our findings offer new insights into the temporal and genetic regulation of acquired ...

Biotropica, Volume 58, Issue 4, July 2026.ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...
