Jacob Burckhardt's interpretation of the renaissance was a prototype of the modern world. Scholars think he overlooked the continuity between the middle ages and the renaissance. Also other renaissances had revived ancient things like Greek science, the Latin language, and a liking of the worth and creativity of individuals. To fifteenth-sixteenth century Italy the term meant a time of growth.
A kelp forest off of the coast of Anacapa Island, California. Giant kelp uses gas filled floats to keep the plant suspended, allowing the kelp blades near the ocean surface to capture light for photosynthesis.
Pacific Kelp Forest Urchins. Photo by Paul Banko. This lovely photograph shows the three common urchins found in eastern Pacific kelp forests. Red = Strongylocentrotus franciscanus; Purple = Strongylocentrotus purpuratus; White = Strongylocentrotus droebachiensis.ereocystis luetkeana often dominates northeastern Pacific kelp forests. It has a long stipe that is attached often to a small rock and is kept aloft by a gas-filled float. The fronds extend from the float. This makes for a very unstable arrangement and strong storms often uproot the plant.
