  • Title: Motile chemosensory behaviour of phagotrophic protists: mechanisms for and efficiency in congregating at food patches.
    Author: Fenchel T, Blackburn N.
    Journal: Protist; 1999 Oct; 150(3):325-36. PubMed ID: 10575704.
    Abstract:
    Phagotrophic protists are capable of congregating at point sources of food within a few minutes, from distances of up to several cm in the case of ciliates, or several mm in the case of microflagellates. This is exemplified by four ciliate species and a heterotrophic flagellate. Congregation is accomplished by the combined effect of more than one type of chemosensory motile behaviour including "kinetic responses", "temporal-gradient sensing", and "helical klinotaxis". The results are discussed in terms of microscale patchiness in nature.
