Since 1986, Dr. Anita Brinckmann-Voss has assisted the students and faculty of Lester Pearson College with her understanding of marine invertebrate ecology and her expertise in the taxonomy of hydroids. These small colonial animals, the alternate stage of the life-cycle of jellyfish, occur in rich profusion underwater at the Race Rocks Marine Ecological Reserve. |
| Dr. Anita Brinckmann-Voss lives in Sooke, on Vancouver Island, British Columbia, Canada |
When the original species list was done for the Race Rocks Ecological Reserve Proposal, in 1979, only 2 hydroids had been included on our species list. Now over 60 species have been identified by Anita and she continues to assist students with research projects while she furthers her research on specimens from the island. Anita has established long term research plots in a tidepool at the reserve and documents the distribution of hydroids underwater with the assistance of students and faculty in the Diving program at Lester B. Pearson College. |

Anita accompanies Garry, Chris and Joe on a dive to Secretary Island, West of Race Rocks up the Strait of Juan de Fuca towards Sooke. The purpose was to collect samples for hydroid specimens.Click here for 56kbps version |

Archipelago (Washington, USA) . Canadian Journal of Zoology 71: 401-406
ABSTRACT:
A new species of colonial athecate hydroid, Rhysia fletcheri ,is described from Vancouver Island, British Columbia, Canada, and from Friday Harbour, Washington, U.S.A. It's relationship to Rhysia autumnalis Brinckmann from the Mediterranean and Rhysia halecii (Hickson and Gravely) from the Antarctic and Japan is discussed. Rhysia fletcheri differs from Rhysia autumnalis and Rhysia haleciiin the gastrozooid having distinctive cnidocyst clusters on its hypostome and few, thick tentacles. Most of its female gonozooids have no tentacles. Colonies of R. fletcheri are without dactylozooids. The majority of R. fletcheri colonies are found growing on large barnacles or among the hydrorhiza of large thecate hydrozoans. Rhysia fletcheri occurs in relatively sheltered waters of the San Juan Islands and on the exposed coast of Southern Vancouver Island.

subtidal habitats at Race Rocks, off Vancouver Island,Canada, Scientia Marina Advances in Hydrozoan
Biology , Vol 60 (1):89-97
Abstract:
An assemblage of 27 hydroid species was reported from a tide pool in the lower rocky intertidal zone, and
compared with 42 hydroids of the adjacent subtidal region. Location of hydroids within the pool, seasonal
occurence, growth and sexual maturity were tabulated, and some systematic aspects discussed. Possible
causes of hydroid species diversity were considered, including location of the tide pool in an area of tidal rapids,
and shading by surfgrass and rock cliffs during low tide
