A bioRxiv preprint reports nine high-confidence hybrids between invasive Bursaphelenchus xylophilus and native B. mucronatus in Japanese field samples. Genome-wide analyses identified both F1-like and advanced backcross-like individuals, including some missed by a single-locus test.

A bioRxiv preprint comparing rats with Chinese tree shrews reports that tree-shrew CA1 uses a hybrid spatial code, combining weaker position tuning with more multiplexed neural activity. The findings suggest that spatial representations can change within a conserved hippocampal circuit while retaining core network properties.
