Field Studies 6: 1-51 Comments: It can produce multiple broods in a year, depending on temperature and food availability, with the ovaries redeveloping as each brood matures. |
Reproductive type (?) | Sexual References: Barnes H, Barnes M (1965) Egg size, and their variation with local, geographical, and specific factors in some common cirripedes. Journal of Animal Ecology 34(2): 391-402 Rainbow PS (1984) An introduction to the biology of British littoral barnacles. Field Studies 6: 1-51 Comments: An average sized animal produces about 1800-4000 eggs and using a generation time of only 14 weeks and release of 12 broods per year. Eliminius modestus produces successive broods throughout the year, each brood being released after 2 weeks (Barnes & Barnes, 1968). |

Temperature and Salinity Tolerances Predict Range Expansion for Two Invasive Marine Invertebrates. PhD thesis, MIT Sea Grant College Program MITSG Center for Coastal Resources, Cambridge MA Comments: larvae survive in 20-35 psu breeding can occur at 16 psu or lowe, but only for a short time |
Habitat modifying ability potential (?) | Autogenic ecosystem engineers References: Crisp DJ (1958) The Spread of Elminius Modestus Darwin In North-West Europe. Journal of the Marine Biological Association of the United Kingdom, 37: 483-520 Comments: Bioconstructor: Eliminius forms a dense cover that spaces left by death individuals, that are soon filled by the rapid grow of surrounding members of the species. Therefore E. modestus displaces gradually other local species, competing for space. |
