The algal flora of the Brigham Young University campus is more diverse than previously thought. Sixty-eight genera containing 160 species of Chlorophyta, Euglenophyta, Chrysophyta, and Cyanophyta were collected and identified. The greatest number of species was obtained from a small pond in the arboretum, with progressively fewer species obtained in the irrigation canal partly surrounding the campus and in specialized habitats in the greenhouses.

The Life Cycle Of Hydroperla Crosbyi (Plecoptera: Perlodidae), Reed Y. Oberndorfer, Kenneth W. Stewart

Great Basin Naturalist

Hydroperla crosbyi in Texas exhibited a univoltine, fast life cycle over the three-year study period. Adults emerged in February–March when mean daily stream temperature reached ca. 15 C. Reared females in the lab deposited up to three egg masses. Mean fecundity of dissected females was 787 eggs/female. Oviposition in the field was observed and described.

Eggs were triangular in cross section, brown, and measured 400 µm × 535 µm. They underwent an ca. seven-month diapause until mean daily stream temperature decreased to 18 C. Eyespots appeared, and hatching followed in two to three weeks. First instar nymphs were measured and …
