Dietary metabarcoding reveals the simplification of bird–pest interaction networks across a gradient of agricultural cover

Molecular Ecology, Volume 33, Issue 8, April 2024.
Abstract Agriculture is vital for supporting human populations, but its intensification often leads to landscape homogenization and a decline in non‐provisioning ecosystem services. Ecological intensification and multifunctional landscapes are suggested as nature‐based alternatives to intensive agriculture, using ecological processes like natural pest ...

Dhurrin content and biomass yield in sorghum hybrids throughout plant growth cycle

Agrosystems, Geosciences &Environment, Volume 7, Issue 1, March 2024.
Abstract In recent years, the use of sorghum [Sorghum bicolor (L.) Moench] in crop rotation as a green manure to decrease nematode infestation and promote the growth of subsequent crops has strongly increased. The reason why sorghum is effective in biofumigation against root‐knot nematodes is because it releases dhurrin, a cyanogenic glycoside found in

Temporal mismatches in flight activity patterns between Pipistrellus kuhlii and Prays oleae in olive farms: Implications for biocontrol services potential

Journal of Applied Ecology, Volume 61, Issue 3, Page 526-537, March 2024.
Future research should consider mismatches between the temporal activity patterns of insectivorous bats and insect pests. Otherwise, the actual impact of agricultural intensification on bat‐mediated biocontrol services as well as the economic impact of their loss on the agriculture industry might be underestimated.
