Pyramimonas sp. The Race Rocks Taxonomy

pyrampool

On the east side of the island is the largest pool with Pyramimonas.

Pyramimonas is a green micro-algae, that is a type of phytoplankton.

Phytoplankton refers to the autotrophic component of the plankton that drifts in the water column.

Here it is photographed at 400X under the microscope.

Most phytoplankton are too small to be individually seen with the unaided eye. However, when present in high numbers, their presence may appear as discoloration of the water (the color of which may vary with the phytoplankton present). This is certainly the case in the high intertidal tide pools at Race Rocks

In the high intertidal areas of Race Rocks, there are tidepools with wide fluctuations of abiotic factors. The organisms inhabiting these pools are well adapted to these extremes. Garry talks to a biology class about some of the variables influencing these high tide pools, and the flagellated green algae living within them.

The intense green color of the pools, swirly coloration of the water and a frothy covering early in the day indicate high photosynthetic capability. These plankton have an interesting response to changing salinity referred to in the video above.

Phytoplankton, like other plants, obtain energy through photosynthesis, and so must live in the well-lit surface layer (termed the euphotic zone) of an ocean, sea, or lake. Through photosynthesis, phytoplankton (and terrestrial plants) are responsible for much of the oxygen present in the Earth’s atmosphere.

pyramdiagPhytoplankton is consumed by microscopic animals called zooplankton (these are the second level in the food chain).
Zooplankton is consumed by Crustaceans (the third level in the food chain).
Fish that eat crustaceans could constitute the fourth trophic level, while seals consuming the fishes are the fifth.

LAB: Using Temperature and Salinity Data for an Excel exercise

Purpose:
To transfer Environmental Data being recorded at Race Rocks from a spread sheet presented on the internet to your own computer in order to be able to graph trends and analyze relationships.
Background:
Long term data bases are very important for a number of reasons. You may wish to write down in your assignment notes some of the applications you could use for such data. Certainly patterns of cyclic activity and even events such as Climate Change can be detected from the Race Rocks Data. Try to come up with a few other applications. We intend to make a complete range of environmental data from data sensors as these get installed.

RACE ROCKS TEMPERATURE AND SALINITY EXERCISE
Since 1921 the Light keepers at Race Rocks have recorded some basic climatic data at Race Rocks. They started by taking daily sea water temperatures and in 1936 added daily salinity measurements to their measurements. The record is fairly complete except for a few years during the second world war, and so far we have not been able to determine why those records were not kept at that time.
1.This is a file with the daily sea temperatures and salinity and atmospheric data since the year 2000, as recorded by Mike Slater:2. We were able to get this complete monthly mean data base for Temperature….1921->present and this complete monthly mean data base…1936-present for Salinity from the Institute of Ocean Sciences.

3. Copy and Paste the data for the years you want to analyse from the web page directly into your blank EXCEL workbook.

4. You now have our original data on your computer and you can proceed to do any one of the many manipulations possible in the EXCEL program. You can also copy and paste in other month’s data in order to get a larger data set .

5. Take the opportunity to creative in the way you look at and interpret data, we would be interested in attaching your findings to this website. Send comments to: Garry Fletcher Just e-mail your analysis as an attachment.

6. You are welcome to use this data for educational purposes, you are just asked to reference the source as:

Membranipora serrilamella: Kelp-encrusting Bryozoa

The colonial marine bryozoan Membranipora serrilamella, formerly referred to as Membranipora membranacea. produces a planktonic larva that is encased by a triangular bivalved shell. Following a relatively long free-swimming phase, the larva settles as an epizootic colony on the blade of laminarians and other subtidal marine algae. It then undergoes a metamorphosis to become the sessile progenitor of the colony, referred to as the ancestrula”.

Encrusting colonies are typically found on marine algae on the lower shore to shallow water. Found encrustating in kelps and other large seaweeds, especially common on the brown algae Laminaria, but can also be found growing in rocks, glass, floats or other.
Description: This epiphiytic bryozoan forms encrusting lacy matlike colonies of very small, rectangular aurozooids 0.42 x 0.13 mm. with tubercules or short spines in the corners. Each zooid has lateral calcified walls that contain ventral incalcified bands providing flexibility; A frontal membrane completely roofs the space between the supporting side walls with a lophophore (feeding tentacles) visible within. Tower zooids may also be present, where the frontal membrane projects upwards in a columnar way. Forms white, disc-like colonies, approx. 1 mm high and up to and over 100 mm wide. Zooids are rectangular and for together neatly in radially arranged rows that grow outward and branch into new rows as the pattern frows wider.
Additional information: Colonies may vary in size. Membranipora membranecea grows quickly (several mm/ day) in response to predation from sea slugs and in order to maintain its position on the kelp frond. Prolific growth is favoured by fast flowing water which provides food and oxygen. Egg production occurs once a year in the spring; the larva (cyphonautes) is planktotrophic and is the most abundant and largest coastal larva in Britain between June and August. The larva settles in late simmer-early autumn.
Natural history: Colonies are made up of hundreds or thousands of individual zooids, which are not much larger than a pond head. Their eight week growing season falls between late spring and early autumn. During this time, how they grow is dependent upon their success in the competition for space. The interaction between colonies can be cooperative to aggressive depending upon their size. Small colonies communicate by using electrical signals. Large colonies use runners called stolons from which new zooids bud from to mediate aggressive behaviors.

Caloplaca sp: orange/yellow Lichens – The Race Rocks Taxonomy

Caloplaca sp.

A symbiotic phenotype of lichen-forming fungi. The lichen observed here is thought to be a combination of Caloplaca flavogranulosa and/or C. citrina

Appearance: The tissue of this species is yellow-orange and often found in small yellow patches (colonies), and it is difficult to discern separate individuals. It has a very brittle appearance. In general, colonies may form a distinct narrow band on rocks and walls just above high water level, so that they are moistened by the water.

The body has a checkered cracked look with a finely frayed, whitish or pale yellow edge that is composed of the lichens (fungal) hyphae. The fruiting structure has a dark orange disc that is surrounded by a lighter edge.

Structure:
Structure of the common which grows on many types of surface, including concrete, roofs of buildings, and rocks subjected to sea spray. The orange colour of this lichen is due to production of the pigment parietin at the lichen surface.
Habitat:

They grow is soiless habitats such as on rocks, on trees, on walls, or on poorly developed soils. Although found in all biomes, lichens are particularly abundant in high altitudes like the Sub-Antarctic, the Arctic, the Antarctic.

In this observation it was found that the species was very high up on the rocks of the island. They were found in vast patches, at a position where the waves only reach as surf spray..

This lichen can build small yellow patches amongst the darker belts of salt lichen nearer to the shoreline, but is more common higher up and can build widespread yellow-orange colonies on the shorelines middle zone. Orange lichen is perennial and colonies grow slowly.

-Common on nutrient rich areas such as beneath bird perching areas.

-appears in areas that have limited water spray , and salt concentration is high.

Niche:

The lichen is a photosynthetic organism. Lichens are remarkable for their ability to withstand prolonged drying and to resume activity rapidly after re-wetting. Most lichens that contain green algae can recover from drought by absorbing water from humid air and then begin to photosynthesise. In this habitat there are not many grazers on lichen.

Limiting Factors:

-excess amounts of water, oil spills, or coverage by animal (bird, sea lion) faeces may lessen rate of photosynthesis

-trampling, erosion by water spray, may kill some of the population

The Race Rocks Weather Station

 

October, 2005 Chinyere and Juan Carlos inspect the Davis Weather Instrument that we have installed at Race Rocks for real-time monitoring and archiving of meteorological events.

 

Several individuals and groups have helped us in implementing this weather station. In particular we must mention the anonymous gifting to Race Rocks of two G4 Computers from our friend Julia from Boston. The weather instrument console originally interfaced with one of these computers and regularly transmitted the data by FTP to the Telus internet server.  Now a computer supplied by Pearson College transmits this data to a different server used by this website.
Thanks also to Mike Slater for an excellent job of installing the mast and the conduit for the instrument, and for the remote help in keeping the software running through our internet connection.

Funding of the weather instrument and installation work was originally funded byThe B.C. Ministry of Energy and Mines to assist in the upgrading of Internet services from the Island and to up-date monitoring of the environmental factors as part of the Pearson College, ENCANA, Clean Current Demonstration Tidal Power Project.

You may be able to find a Davis Weather Instrument in your neighbourhood too !

Imagine my surprize in April 2007 when I came across this Davis Weather Instrument operating behind the Bayon Temple at the Angkor Wat World Heritage Site in Cambodia.

 

Tidepool # 6 “Anita’s Pool”

On the West side of Great Race Rocks is a tidepool that we have been observing for many years. Dr. Anita Brinckmann-Voss has done research on the seasonality of hydroids in this pool and it is published as:

Dr. Anita Brinckmann-Voss doing research on seasonality of Hydroids in Tidepool #6

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

The unique feature about this pool is that it is deep enough – ( 1 meter) and it gets swells that refresh it even when the tide level is low. Garry is standing on the lip of the pool as the water from a swell spills out and cascades down to the lower level of the ocean.

History of the Klallam Name for Race Rocks

xwayenmThis word written in the Klallam language means “fast flowing water”, the area around Race Rocks. The late Thomas Charles of Beecher Bay First Nations provided this name in March of 1999. It was transcribed from the word written out in Klallam by his wife Flora Charles .(See details below)

We are grateful to Burt and Lee Charles, the late Thomas Charles, Tom Sampson, Andy Thomas, Vern Jacks, and Earle Claxton who have helped us to understand how important the coastal waters and Race Rocks are to the Salish people and their culture. We believe we started on a fruitful path in involving local First Nations people in the educational program at the Race Rocks MPA. This will allow us all to better understand the science and conservation principles practiced for generations on this coast.

rrlogocolxwmMuch of what we are now doing at Race Rocks and the surrounding area is not new. For countless generations Sooke Basin, Beecher Bay and Pedder Bay provided shelter and ideal locations for First nation communities. The great wealth of sea-life provided generous opportunity for harvesting of foods and medicines. Careful conservation techniques, passed down through the generations ensured the resources were managed in a truly sustainable manner, at least until the arrival of the Europeans. On Tom Sampson’s advice, we suggest you read the Bamberton Report which provides considerable detail of the cultural dependence that First Nations people have on the land and the coastal areas of the Salish Sea. Tom sees the report as a valuable model for the way we should respect the knowledge of First Nations people when we create plans for managing protected areas.

For more than just the most recent millennia, people lived and worked as an integral part of the coastal ecosystems of Southern Vancouver Island and the Strait of Juan de Fuca. They managed the resources for their own survival. They valued the land and the water ecosystems because they did not see themselves as separate from those systems. Place names were important since only through the language can one understand the importance of natural areas to the First Nations people.

earlinvertsOn a visit to Race Rocks with Tom, Andy and Vern, we were told of the way their people would use the gull eggs in a sustainable way so that they would always have some for later. The sea urchins were also a special food. Their power was such that only those of a certain age could eat them, as the eggs were too strong for the younger people. Sea cucumbers had their top end cut off, were cleaned out and then stuffed with other kinds of food. Mussels and barnacles as well as the myriad of snails, whelks, chitons and other intertidal invertebrates were standard fare for the people. The area also provided a wealth of the standard fish resources. Often seafood that was collected was traded with the interior people from Washington, as far as the South end of Puget Sound.

In early1999 the Marine Protected Area Advisory Board indicated that we would like to acknowledge First Nations traditional use of the Race Rocks MPA with a name in the local Coast Salish Language.

In March of 1999, Tom Samson and Angus Matthews visited one of the oldest Klallum-speaking elders, the late Tom Charles and his wife Flora who were living then in Beecher Bay. He asked them if they could help to provide the place names for the area and a name for the Race Rocks MPA. Thomas had strong memories of the traditional ways. (Sadly, Thomas Charles passed away in December of 1999.) In his discussion with Tom Samson, he recorded some of the place names of this corner of Vancouver Island and gave a sense of how their ancestors lived within the ecosystem. Location and language is so important to them when talking about culture. The late Flora Charles wrote down the words that the late Tom Charles spoke in Klallum so that the Advisory Board would be able to use them. This is a copy of the words Flora Charles wrote out for the Advisory Board. The area from Pedder Bay to Beecher Bay was a community that was totally dependent on the coastal resources well into the twentieth century. Race Rocks was known as xwayenthe area in which one could get any kind of food they needed. Thomas Charles remembered his parents going to sell ling cod from Race Rocks the area of “Xwayen” (the word written in the Klallum language means “fast flowing water” to the buyer in Pedder Bay, “Whoayinch” in the 1920’s. Church Island, visible from Race Rocks out in front of Beecher Bay was ” Kquitong”, the Raven’s hang out.
See spelling in Klallam below:

They recorded the conversation, and Flora Charles wrote down the Klallam spellings shown in her handwriting below. An audio casette of this conversation is included in the Pearson College librarytcharles

Another Earthquake Last evening, about 20 minutes to 6 o’clock, another shock of an earthquake was felt in this city. It lasted about 10 seconds and was not nearly so heavy as the shock Saturday night. Mother Earth is evidently preparing for a grand effort on the Coast. The Old Lady has been quiet in this neighborhood since 1868; and she should certainly be allowed a little frolic at the “gay and festive” season of the year.
