Interactions of rare earth elements with living organisms and emerging biotechnical applications

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1251-1274, September 2025.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Ants on flowers: Protective ants impose a low but variable cost to pollination, moderated by location of extrafloral nectaries and type of flower visitor

Journal of Ecology, Volume 113, Issue 8, Page 2187-2198, August 2025.
Individuals who engage in multiple mutualisms often have to pay indirect costs because of the interference of one mutualism on another. We found that protective ants had a low but variable impact on pollination, especially on the flower visitation by bees and when EFNs are close to inflorescences.

Natural forest colonisation as a management strategy to restore soil functioning of abandoned agricultural lands

Journal of Applied Ecology, Volume 61, Issue 11, Page 2690-2700, November 2024.
Though its effectiveness is variable, passive restoration can be more effective than active restoration. Our research indicates that passive tree colonisation of past agricultural land is enough to achieve soil functionality similar to a mature forest for most variables studied. However, some variables would need more time to reach mature forest levels,

Cytological evaluation, culture and genomics to evaluate the microbiome in healthy rabbit external ear canals

Veterinary Dermatology, Volume 35, Issue 5, Page 479-491, October 2024.
Background – Lop‐eared rabbits may be predisposed to otitis externa (OE) as a consequence of their ear conformation. Although otoscopy, otic cytological evaluation, and culture are valuable tools in dogs and cats, published data on rabbits remain lacking. Hypothesis/Objectives – This study aimed to assess the utility of otoscopy and cytological results
