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). WebThe most widely known functional classification of diatoms is based on diatom guilds (Passy, 2007). Taxa are assigned to a guild based on similar resource use capability and …
WebJul 20, 2024 · This review deals with a very particular substrate that consists of large benthic and motile diatoms. It is about passively motile epidiatomic diatoms. Their mode of attachment is similar to that of epiphytes on macrophytes, so they are also referred to as epiphytes, with the assumption of a negligible impact on the host's fitness. Host ...
WebDiatoms are mostly non-motile; however, sperm found in some species can be flagellated, though motility is usually limited to a gliding motion. In centric diatoms, the small male … WebIn the present work, deformation and migration behavior of non-motile unicellular phytoplankton diatoms subjected to viscous shear flow are considered. These unicellular diatoms develop into colonies which are made up of linked chains. The complex fluid-structure interaction is solved by developing a two-dimensional numerical model with an ...
WebA resting spore can be a spore created by fungi which is thickly encysted (has a thick cell wall) in order to survive through stressful times, such as drought. It protects the spore from biotic ( microbial, fungal viral ), as well as abiotic (wind, heat, xeric conditions) factors. Resting spores of a particular fungus are known create the ...
