Fragmentation7
  • Due to the species' sensitivity to fragmentation in response to strong water movement, hydrodynamic conditions (e.g. waves, pass and lagoonal circulation) corresponded to marked differences in colony size distributions, morphology and recruitment dynamics among habitats. (plos.org)
  • In the latter habitat, most colonies grew as vertical sheets on encrusting bases making them more vulnerable to colony fragmentation, whereas fire corals were encrusting or massive in all other habitats. (plos.org)
  • Fire corals can colonize a wide range of reef environments through sexual reproduction [ 7 , 8 ] and colony fragmentation [ 7 , 9 ]. (plos.org)
  • Fragmentation is a form of asexual reproduction through regeneration of tissue. (actforlibraries.org)

Binary fission3
  • Asexual reproduction of bacteria mainly occurs through binary fission while sexual reproduction occurs through conjugation. (pediaa.com)
  • Reproduction is usually asexual by binary fission and can occur several times a day. (microscopyu.com)
