Levi Lewis, graduate student at Scripps Institution of Oceanography at UC San Diego, measures the density, diversity and height of algae in one of 40 experimental plots, which he has established across 500 meters of natural reef in the Kaanapali region of West Maui, Hawaii.
As part of his dissertation research, Lewis is testing the relative importance of different species (and combinations of species) of herbivorous sea urchins on a natural reef in Maui, Hawaii.
“Coral reefs persist where a balance is maintained between coral and algal growth. The ultimate goal of this particular project is to assess the similarities and differences in the effects of each species of urchin, as well as the consequences of species combinations, on the algal and coral communities,” said Lewis. “The results of such a quantification will tell whether mono-specific, or multi-specific communities of herbivorous urchins might result in the most effective control of algae, and facilitation of coral growth.”
According to Lewis, there is a rapid loss of coral reefs and around the world. It is important that we understand the factors that improve coral reef resistance to algal phase shifts.

This reminded me that I have forgotten a lot of my biology for the benefit of microbiology. :-)
Fascinating to see them in person, nonetheless. More than seeing them in books! -)

D, cross section of an internode. E, of a node of a somewhat older leaf. F, G, young sexual organs seen in optical section. o, oögonium. An. antheridium. H, superficial view. G, I, group of filaments containing spermatozoids. J, a small portion of one of these more magnified, showing a spermatozoid in each cell. K, free spermatozoids. L, a piece of a leaf with ripe oögonium (o), and antheridium (An.). B, H, × 150. J, K, × 300. I, × 50. L, × 25.
Years ago my middle school students studied and photographed filamentous green algae in the classroom, under the microscope. I snagged this one to test out the camera and as a practice shot, to prepare to show them the necessary technique.
This photo is a bit out of focus, so it doesn't illustrate how excellent that little Coolpix was for this type of photography.
The study included samples from Upper Klamath Lake and surrounding canals serving agricultural fields. Shown here is graduate student, Lindsay Collart, carrying out water sampling. Photo provided by OSU College of Science.
A nicely colored algae culture caught my eye in the experimental section of the Cabrillo Marine Aquarium in San Pedro. I had to be in San Pedro on a non-related matter the other day and I had not been at the aquarium in a few years. So I decided to stop and I was happy to notice that they expanded their facilities and have two whole sections where biologists work with marine plants and animals, one of them dedicated to kid.

weather was perfect for shooting after days of raining, the sun finally came out and every was green.

Not sure why, but I ended up working a lot with this picture and now I can't decided which version I like the best, so I am uploading all four! Taken in the grounds of Michelham Priory, England.
Aquarium at the end of April with water crystal clear. There was an algae bloom but it was temporarily gone.
Turns out they're not making the car fuel of the future, more the super-food of the future.
The algae are excellent for making the popular Omega3 oils and that's great cause then you don't have to kill off fish to make the oils.
They had open house during Christmas but I missed that, too bad.
Here's a short video about them on a site called Mashable:

in spring the ground begins to thaw. strong winds catch the tallest trees and sometimes their shallow roots just peel away with the top few softened centimetres of forest floor, leaving the frozen ground beneath.
