Dr. Anita Brinckmann-Voss and Hydroid Research at Race Rocks

anitaDr. Anita Brinckmann-Voss  passed away in December of 2017.

From 1986, to 2005,  Dr. Brinckmann-Voss of Sooke, BC 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.  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 continued to assist students with research projects while she furthered her research on specimens from the island until 2004. 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. Below: Anita accompanied 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.

 1. Brinckmann-Voss, A. , Lickey, D.M. , and Mills, C.E. 1993 Rhysia fletcheri (Cnidaria, Hydrozoa, Rhysiidae), a new species of Colonial Hydroid from Vancouver Island British Columbia, Canada) and the San Juan 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 halecii in the gastrozooid having distinctive cnidocyst clusters on its hypostome and few, thick tentacles.
  • hydrfemeMost 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. Colored photos of Rhysia males. females and gastrozooids are included.

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 occurrence, 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 surf-grass and rock cliffs during low tide.

Tidal Currents and Current Measurement at Race Rocks

The current at Race Rocks had just changed to a flood – it would be getting up to 6 knots in a few hours, so it was probably at about 5 knots at this time.

Adopt an Ecosystem


BACKGROUND: “Adopt an Ecosystem” involves using the internet as a means to get individuals and groups in other communities: provincial, state, national and international, involved in collaborating with others, and providing an educational resource while ensuring the stewardship of their own local ecological resources.

OUTLINE WITH POWER POINT PRESENTATION:
This 10 step outline presents the basic model of how to go about setting up an Adopt an Ecosystem Project in your school or organization.

 

THE PROCESS:
We are urging individuals, school groups and service groups in communities to establish internet files on a local natural area which they are able to document easily at a number of levels of scientific sophistication. This natural area may be a small corner of a school yard, a piece of coastline, a local stream or pond, or it could be an established ecological reserve or park. Valuable long-term baselines can be established with students of each year or individuals leaving a “digital legacy’ or a permanent on-line record which is available for other classes to make additions and updates in the future.
THE IMPORTANCE OF THE “PROCESS”

By involving individuals in the documentation and monitoring of their adopted ecosystem, a sense of “ownership” of one’s ecosystems and responsibility for their stewardship is experienced. In addition participants are encouraged to use technology to assist in the accumulation of valuable long-term ecological information which can serve as baselines for environmental impact decisions in the area, and as a valuable baseline on the area’s biodiversity.

OBJECTIVES: (The teacher and class may decide on setting their goals for this project, using only a limited number of the suggested activities.) After doing this assignment, students will be able to:

a) Design a plan and procedure for the creation of a local : “Adopted Ecosystem”

b) Use field methods involving quantification to document the chosen ecosystem with a baseline inventory.

c) Use a Spreadsheet program for the analysis and recording of locally collected data.

d) Set up a weather station for collection of weather data.

e) Construct a species list and/or taxonomy of the local organisms in the “Adopted Ecosystem”.

f. iNaturalist contributions Recently I opened an account on iNaturalist.com . I have been able to add many pictures of species taken around the Metchosin coast, as well as other locations. https://www.inaturalist.org/observations/garryf

It is a great idea to contribute to iNaturalist so by opening a free account on iNaturalist.com it  is a good way to do establish a baseline for organisms in your ecosystem and get professional assistance from experts for identification of species.  for instance for the biodiversity project the following entries are recorded by various individuals, https://www.inaturalist.org/projects/metchosin-biodiversity

f) Setup a website dedicated to the collection of resources relating to your locally adopted ecosystem.

g) Outline the Ecosystem Services and the value of the Natural Capital of your adopted Ecosystem.

PROCEDURE:. Identify the area and describe the ecological features that make the area unique, important or just representative of other surrounding ecosystems. Also indicate what your group intends to do with it.

2. You may indicate time lines for your goals, and even designate responsibilities to different group members in order to help you plan your strategy.

3. Establish a good “baseline inventory ” of what is there presently. Many ecological techniques are available to quantify organisms and their distribution. You may use our Transect Files as an example.

4. Establish a class project to provide a taxonomy of the species of your local ecosystem.

5. Include dated maps, databases, taxonomic inventories, checklists, photographs, videos or drawings to document your site. Open a project on iNaturalist.com  that enables you to enter photos of species and have experts help in making identifications

6. Begin monitoring the site for aspects of its structure and function. For structure: what living things are there, how they are distributed, what relationships or biotic associations exist. Also, the structure includes physical factors such as temperature, salinity, etc. –start gathering long term data, enter it into a database (such as excel), and save it to the internet site so that others can download and manipulate the data.

7.Download Google Earth and make a 3 dimensional image of the area with your ecosystem.

8. Search for historical and other recent maps or charts of your area. Include these as part of the information recorded.

9. If you have access to your own internet site, assemble the information on the site, let us know its location and we will provide a link to your site from racerocks.ca.

10. Establish a Project to list and value the Ecosystem Services and Natural Capital of your ecosystem. In recent years, we have started to acknowledge that “ecosystem services ” are something to which we must start paying attention as to fail to do so leads to a decline in quality of life:
This file explores that idea further and invites you to contribute to a new project : Defining the Ecosystem Services of Race Rocks. By looking at the model of such services developed for Race Rocks, you might also get an idea how you could choose a part of your own local ecosystem and do a similar analysis.

11. In the fall of 2005 we installed a Davis Weather Instrument at Race Rocks for real time monitoring of a number of meteorological events.

From this environmental data index page, you can see how we are developing pages for each environmental abiotic factor and interpreting how that factor is important in the ecosystems of Race Rocks. Many schools already have weather stations installed. Here are some examples from the Victoria area:
