Information

Ecological parameter:  reproduction according to Tachet

Parameter group: life parameters

Explanation:
This trait takes into account both sexual and asexual reproduction. Asexual reproduction, usual and diverse in primitive phyla, has not been detailed, due to a lack of information for many genera. Oviposition tactics have been mainly detailed within the reproductive strategy. Eight categories have been defined.

Additional information:
Note that Several classifications of the Tachet database are on higher taxonomic level than on species level. To display them in the list please enable "include higher taxonomic units" in the "advanced search".
