Sub-species level (?) | Not entered |
Native origin (?) | Not known References (not structured): Atanacković, A., Zorić, K., Paunović, M. 2021. Invading Europe: the tropical aquatic worm Branchiodrilus hortensis (Stephenson, 1910)(Clitellata, Naididae) extends its range. BioInvasions Records, 10(3), pp. 598-604. Comments: Native distribution related to Asia, Australia and Africa. |
Life form / Life stage (?) | Unknown |
Sociability / Life stage (?) | Unknown |
Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Asexual References: Atanacković, A., Zorić, K., Paunović, M. 2021. Invading Europe: the tropical aquatic worm Branchiodrilus hortensis (Stephenson, 1910)(Clitellata, Naididae) extends its range. BioInvasions Records, 10(3), pp. 598-604. Comments: Sexually mature specimens are rarely found in Europe but have been observed in large numbers in native habitats in Asia. As a result, asexual reproduction by paratomy is typical for this species and its spread is probably supported by the water current. |

Association with vessel vectors (?) | Unknown References: Atanacković, A., Zorić, K., Paunović, M. 2021. Invading Europe: the tropical aquatic worm Branchiodrilus hortensis (Stephenson, 1910)(Clitellata, Naididae) extends its range. BioInvasions Records, 10(3), pp. 598-604. Comments: The vector of introduction for B. hortensis remains unknown. The populations in the Danube could be the result of ballast water introduction (first introduction in Slovakian river stretch and second introduction in Serbian river stretch), but this vector is less likely in canals where there are no commercial shipping or barging routes that could connect these populations. |
