Reproductive organs and spermatogenesis of the peculiar spermatozoa of the genus Kryptodasys (Gastrotricha, Macrodasyida), with an appraisal of the occurrence and origin of the tail‐less spermatozoa in Gastrotricha

open access: yesJournal of Zoological Systematics and Evolutionary Research, Volume 59, Issue 8, Page 1673-1688, November 2021., 2021
Aflagellate spermatozoa in two species of Kryptodasys are reported. Their ultrastructure shows common features, which appear peculiar to the genus and different from those of male gametes of Dolichodasys, the only other macrodasyidan genus known to have aflagellate sperm.

Seasonal turnover in community composition of stream‐associated macroinvertebrates inferred from freshwater environmental DNA metabarcoding

open access: yesEnvironmental DNA, Volume 3, Issue 4, Page 861-876, July 2021., 2021
Macroinvertebrate communities are crucial for biodiversity monitoring and assessment of ecological status in stream ecosystems. Here, we use environmental DNA metabarcoding of filtered water samples collected in both spring and autumn from five streams in Denmark to address seasonal turnover in community composition of stream macroinvertebrates.
