This study examines how climate cycles influenced the demographic history and genomic divergence of cactus wrens in North American deserts, revealing population bottlenecks and sex chromosome-specific recovery patterns.

The paper identifies a novel bacterial endosymbiont in Haementeria leeches, showing genome reduction and B vitamin biosynthesis, and reports the first case of symbiont replacement in leeches without morphological changes.

The paper sequenced three Haementeria leech symbiont genomes, finding conserved B vitamin pathways and an alternative genetic code in one species.

This study uses DNA metabarcoding to analyze the diet of non-haemadipsid leeches and assess their potential for vertebrate and invertebrate monitoring through iDNA.
