Genea
Genea is a genus of hypogeous fungi (truffles) in the family Pyronemataceae, containing approximately 32 species. The genus produces small, soil-colored underground sporocarps that are challenging to locate visually. A 2024 study using scent-detection dogs in western Oregon demonstrated the value of trained dogs in documenting this difficult-to-find genus, revealing abundant occurrence across a wide elevational range and sensitivity to wildfire disturbance.
Tropisternus lateralis limbalis
Tropisternus lateralis limbalis is a subspecies of water scavenger beetle in the family Hydrophilidae. It is known to produce acoustic signals, with males generating sounds that function in mate attraction and courtship. The subspecies has been documented in western Oregon and has a broad distribution across North America extending into South America and the Caribbean.
