The odd couple of protistology: Edward Heron-Allen (1861-1943) and Arthur Earland (1866-1958)
Eur J Protistol. 2023 Sep 14;91:126023. doi: 10.1016/j.ejop.2023.126023. Online ahead of print.ABSTRACTEdward Heron-Allen and Arthur Earland were among the last great amateur foraminifera researchers. Their partnership began in 1907 and ended in 1932. While close in age to one another, they shared little more than a fascination for forams and a lack of any university training. In most other aspects, the two men were completely different. Heron-Allen was a famous upper class polymath, expert not only on forams, but also on the Persian language, violins, palm reading, history, asparagus, and barnacles. He was also an accompl...

Life history of Apocarchesium arndti Norf & amp; Foissner, 2010 (Ciliophora, Peritrichia) including recognition of a novel type of zooid
We report the first record of A. arndti in the Danube and provide a detailed description of its colony development. Our findings support the theory of moderate endemicity and reveal a new, smaller zooid type in A. arndti. This zooid remains attached to the colony, connected to the stalk myoneme but lacks an aboral ciliary wreath. Unlike microzooids, it is incapable of leaving the colony. It exhibits a less spherical shape and arises from the fourth division of the colony-founder cell. Although its specific function is unknown, it is hypothesized to support the stalk dish. Our results have significant implications for under...

Phylogenetic and morphological diversity of free-living diplomonads
Eur J Protistol. 2023 Sep 15;91:126024. doi: 10.1016/j.ejop.2023.126024. Online ahead of print.ABSTRACTDiplomonadida is a lineage of anaerobic protists belonging to Fornicata, Metamonada. Most diplomonads are endobiotic or parasitic, such as Giardia intestinalis, which is a famous human pathogen, but several free-living species exist as well. Although it has been proposed that the free-living diplomonads are descendants of endobiotic organisms and thus interesting from the evolutionary point of view, they have been largely neglected. We obtained 58 cultures of free-living diplomonads belonging to four genera (Hexamita, Tre...
