Developing epidemiological preparedness for a plant disease invasion: Modelling citrus huánglóngbìng in the European Union

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1403-1423, September 2025.
Huánglóngbìng (HLB) is a bacterial disease of citrus that has significantly impacted Brazil and the United States, although citrus production in the Mediterranean Basin remains unaffected. By developing a mathematical model of spread in Spain, we tested surveillance and control strategies before any future HLB entry in the EU.

Water‐saving strategies in rice farming entail cascading effects in prey–predator interactions across ecosystem boundaries

Journal of Applied Ecology, Volume 62, Issue 9, Page 2273-2282, September 2025.
These results show that introducing multiple drainage periods in rice fields (i.e. AWD) indirectly hampers terrestrial spider reproduction through limiting the emergence of potential preys from the aquatic to terrestrial boundaries. MSD resulted in a more conciliatory strategy as it largely reduces methane emissions and does not affect predator–prey ...

Potential conservation of circadian clock proteins in the phylum Nematoda as revealed by bioinformatic searches [PDF]

, 2014
Although several circadian rhythms have been described in C. elegans, its molecular clock remains elusive. In this work we employed a novel bioinformatic approach, applying probabilistic methodologies, to search for circadian clock proteins of several of
