Diatom is motile
Weband the fact that motile diatoms move only when the raphe slit is adjacent to the substratum (although there are exceptions) suggests that the raphe slit is con- nected with motility. The more recent theories concerning the mechanism of diatom locomotion are based on fluid ftow in the raphe slit, the interaction ... WebJul 8, 2024 · The motile guild primarily consists of eutrophic and pollution-tolerant species and is typical of nutrient-rich habitats, and the relationship between nutrient concentrations and diatom motility is well established in literature (e.g. Passy, 2007; Lange et al., 2011; Stenger-Kovács et al., 2013; Jones et al., 2024).
