Sociability / Life stage (?) |
|
Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Asexual Sexual References: Alanis, J., Mossman, L., Sorenson, J., Molina, J. V., Rodriguez, J., Eikenberry, S., & Ferreira, C. P. 2021. Modeling climate change’s impact on Macrocystis pyrifera through population dynamics. Comments: Through a process called alternation of generations, giant kelp reproduce asexually and sexually. Depending on favorable conditions, an adult sporophyte will generate spores via asexual reproduction within its reproductive blades, sporophylls. |
Developmental trait (?) | Spawning References: Buschmann, A. H., Moreno, C., Vásquez, J. A., Hernández-González, M. C. 2006. Reproduction strategies of Macrocystis pyrifera (Phaeophyta) in Southern Chile: the importance of population dynamics. Journal of Applied Phycology, 18, pp. 575-582. |

Salinity tolerance range (?) | Venice system: 6. Polymixohaline [18-30psu] 7. Euhaline [30-40psu] References: Rodríguez, J. P., Terrados, J., Rosenfeld, S., Méndez, F., Ojeda, J., Mansilla, A. 2019. Effects of temperature and salinity on the reproductive phases of Macrocystis pyrifera (L.) C. Agardh (Phaeophyceae) in the Magellan region. Journal of Applied Phycology, 31, pp. 915-928. Comments: M. pyrifera in southern Chile, in its reproductive stages (release of spores, germination, and growth of sporophytes), has a wide tolerance range for temperature and salinity (8 to 18 °C; 27 to 34 psu). |
Habitat modifying ability potential (?) | Autogenic ecosystem engineers Keystone species References: Miller, R. J., Lafferty, K. D., Lamy, T., Kui, L., Rassweiler, A., Reed, D. C. 2018. Giant kelp, Macrocystis pyrifera, increases faunal diversity through physical engineering. Proceedings of the Royal Society B: Biological Sciences, 285(1874), 20172571. Comments: Macrocystis pyrifera is the most widely distributed habitat-forming species and provides essential ecosystem services. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Anthropogenic chemical compounds References: Evans, L. K., Edwards, M. S. 2011. Bioaccumulation of copper and zinc by the giant kelp Macrocystis pyrifera. Algae, 26(3), pp. 265-275. |
Known human health impact? | Known References: Nieto, E. G., Gutierrez, O. H., Moran, N. R., Castañeda, C. C. 2022. Effect of Macrocystis pyrifera (Phaeophyceae, Ochrophyta) on Body Weight Gain, Adipose Tissue, and Liver Tissue in Second-Generation Mice With a Maternal High-Fat Diet.

Marine drugs, 13(3), pp. 1084-1104. Comments: M. pyrifera is a cosmopolitan seaweed that has been widely recognized for its bioactive content which can act as nutrition enhancers and metabolism regulators in food. Fucoidan from M. pyrifera can be potentially useful as a therapeutic agent for infectious diseases, cancer and an effective adjuvant for vaccine |
Known economic impact? | Known References: Gutierrez, A., Correa, T., Munoz, V., Santibanez, A., Marcos, R., Cáceres, C., & Buschmann, A. H. (2007).
