Evaluating 18S Phylogenetic Placement Accuracy to Uncover Hidden Diversity in Non‐Bilaterian Animals
Environmental DNA, Volume 8, Issue 4, July‐August 2026.We assembled the largest curated non‐bilaterian 18S reference dataset and demonstrate that barcode choice strongly influences phylogenetic placement accuracy. Full‐length 18S provides the most robust framework for biodiversity discovery, recovering previously unknown non‐bilaterian lineages, whereas V9 should be interpreted with caution. ABSTRACT Small

Quantitative analysis of cell types during growth and morphogenesis in Hydra [PDF]
, 1973 Tissue maceration was used to determine the absolute number and the distribution of cell types in Hydra. It was shown that the total number of cells per animal as well as the distribution of cells vary depending on temperature, feeding conditions, and ...

ECOLOGICL ASPECTS OF THE MORPHODYNAMICS OF SOME HYDROZOA [PDF]
American Zoologist, 1965 The specific architecture of a Hydroid polyp or a colony is, morphologically speaking, not a stable entity, because it is subjected to an incessant turnover and renewal at both cellular and higher levels. A continuous morphogenetic activity is in many cases (e.g., Hydra ) necessary for the maintenance of the shape and size of the individual polyp ...

Photosynthetic planulae and planktonic hydroids: contrasting strategies of propagule survival
Scientia Marina, 2000 Settlement delays can be important to prevent propagule waste when proper settling substrates are not immediately available. Under laboratory conditions, the planulae of Clytia viridicans underwent two alternative developmental patterns.

Full‐year in situ imaging reveals fine‐scale habitat differences among salp and doliolid life stages
Limnology and Oceanography, Volume 71, Issue 7, July 2026.Abstract Doliolids and salps are pelagic tunicates that reproduce both asexually and sexually during their life history, occasionally forming massive blooms (> 1000 ind. m−3) that can clear large volumes of water daily. Although blooms of doliolids and salps are often associated with pulses of primary productivity, little is understood about their life
