Reading Material

A meme to illustrate some of the things one can read while on an internship.

1. Grab the nearest book.
2. Open the book to page 123.
3. Find the fifth sentence.
4. Post the text of the next 4-7 sentences on your LJ along with these instructions.
5. Don't you dare dig for that "cool" or "intellectual" book in your closet! I know you were thinking about it! Just pick up whatever is closest (unless it's too troublesome to reach and is really heavy. Then go back to step 1).


"In Michgan pools Daphnia ephemeralis appeared in early season and was later replaced with D. pulex, with some overlap.

Although fairy shrimp and clam shrimp occur in the same vernal pools, the fairy shrimp tend to hatch earlier and to complete their develpment before the peak in clam shrimp populations. Mature clam shrimp remain in vernal pools after fairy shrimp have disappeard and appear to be less sensitive to predation. Cladocerans such as D. pulex also remain in pools well into the summer, declining only as the pool dies.

In most vernal pools where fairy shrimp have been studied, only a single species has been reported, but there are records of pools containing two, three, or four species. Co-occuring species of Eubranchipus include E. neglectus and E. bundyi in Ohio and Michigan; E. neglectus and E. holmani in Ohio; E. vernalis and E. holmani on Long Island, New York; E. serratus and E. neglectus in Illinois; E. serratus and E. bumdyi in Illinois; and E. vernalis and E. intricatus in Massachusetts. Usually one species is dominant and the other is present in relatively low numbers, commonly reflecting the broader distribution patterns."
