Application of environmental DNA metabarcoding and quantitative PCR to detect blooming jellyfish in a temperate bay of northern China

open access: yesEcology and Evolution, Volume 13, Issue 11, November 2023., 2023
We developed eDNA metabarcoding and quantitative PCR for the detection and assessment of jellyfish taxa in the temperate Yantai Sishili Bay (YSB) and estimated the spatial distribution of Aurelia coerulea. Our results demonstrate the potential of two eDNA techniques in jellyfish biomass investigation and jellyfish taxa detecting.

Loss of nervous system complexity – Morphological analyses shed light on the neuronal evolution in Myzostomida (Annelida)

open access: yesActa Zoologica, Volume 104, Issue 4, Page 633-646, October 2023., 2023
Abstract Myzostomida are putatively nested within the errant Annelida and exhibit a unique morphology. The latter fact might possibly be related to their long host‐dependent radiation. Hence, an incomplete segmentation, lack of prominent sensory structures in adults and a dorso‐ventrally flattened body are just some examples.
