Generalist predators function as pest specialists: Examining diet composition of spiders and ladybeetles across rice crop stages

open access: yesJournal of Applied Ecology, Volume 62, Issue 8, Page 1889-1901, August 2025.
By quantifying the diet composition of GAPs over crop stages, farm types and years, this study reveals that generalist predators have potential to produce a stable, predictable top‐down effect on pests in rice agro‐ecosystems. Therefore, promoting the field densities of ubiquitous generalist predators will likely enhance pest management and support ...

Effects of Crop Rotation Diversification and Livestock Integration on Above‐Ground Arthropod Dynamics Under Conservation Agriculture

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Diverse crops in conservation agriculture systems can support a variety of arthropods, while sampling methods affected arthropod diversity outcomes. Canola‐Medics‐Wheat‐Medics rotation had a varied effect on arthropod diversity. We suggest that multiple taxa are necessary to compare diversification practices.

Cyanophage Infections in a Sponge Intracellular Cyanobacterial Symbiont

open access: yesEnvironmental Microbiology, Volume 27, Issue 7, July 2025.
Intracellular cyanobacterial symbionts of sponges are shown to be susceptible to cyanophages, challenging assumptions about their isolation from viral exposure. The study reveals novel phage–host interactions and suggests conserved infection strategies across symbionts of marine and terrestrial animals.
