When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

open access: yesEthology, Volume 132, Issue 5, Page 305-316, May 2026.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

Protistan Predators Outshine Fungi in Forest Soil Activity

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Despite extensive research on fungal communities in forest soils, our understanding of the whole eukaryotic diversity and distribution remains limited. Moreover, traditional amplicon sequencing methods often introduce severe PCR and primer biases, further hindering accurate assessment of the microbial community composition in forest soils.

Equipped for success: genomes and metabolomes of the European Amanita muscaria are conserved in its novel South African range

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1863-1883, May 2026.
Summary Plants and soils have been moved around the world for centuries, but invasive mushrooms receive scant attention. The Amanita muscaria species complex was introduced to South Africa in the context of forestry, but its origins, ecology and recent evolution are unstudied. We sequenced the genomes of 24 Northern and Southern Hemisphere A. muscaria,
