Web26 Mar 2024 · Three assumptions should be met in order to allow long-distance dispersal in microscopic aquatic animals: dormancy capability, long-term resistance of dormant stages, and ability to colonise and reproduce quickly. Here I review these assumptions and the direct and indirect evidence we have for long-distance dispersal. Webanimal migration. In migration: Navigation and orientation. Passive drifting is an important factor in the movements of larvae and young fishes, such as those of the eel, cod, herring, and plaice, and even in adult fishes that are passive after spawning, such as herring and cod.

While dispersal in air or water appears passive (but see Dressaire et al. 2016), fungi actively manipulate discharge. Ascomycete and basidiomycete spores are explosively launched (Buller 1909, 1922, 1924; Ingold 1971; Money 1998; Trail 2007), and the ... " - Passive sub floor dispersal layer
