Ovary cord micromorphology in the blood-sucking haemadipsid leech Haemadipsa japonica (Hirudinida: Arhynchobdellida: Hirudiniformes) [PDF]
This is the first report that describes histological and ultrastructural details of ovary organization in haemadipsid leeches. In Haemadipsa japonica, the female reproductive system is organized similar to that of other haemadipsids. Each of the paired and oval ovaries of H. japonica is comprised of the ovary wall (ovisac), which encloses two elongated,

Abstract Aim High‐throughput pipelines supported by eDNA metabarcoding have been applied in various freshwater ecosystems. Both eDNA in ethanol (EtOH) samples (ES‐eDNA) and in water samples (WS‐eDNA) can provide comprehensive classification lists with good taxonomic resolution and coverage for determining freshwater biodiversity and biomonitoring. But,
