The article examines the effect of wave action on movement in the owl limpet, Lottia gigantea, in Santa Cruz, California. The section tests the expected curtail movement of limpets, and reports, for the first time, that natural variation in wave energy is correlated with the decision to move: movement in the owl limpet Lottia gigantea is inhibited at high tide during periods of relatively larger waves. Theoretical measurements and considerations of tenacity gathered predicts that intertidal gastropods should minimize the chances of dislodgement during periods of high waves by remaining stationary.

The article profiles Thomas Kaplan, a wealthy philanthropist who have invested in science conservation to preserve big cats in the U.S. Kaplan has always been fascinated with big cats and it has been his lifelong dream to help in their conservation and prevent extinction. The philanthropist is the financier of several graduate students working on cat conservation around the globe and is also contemplating on pursuing a doctoral degree in zoology. Kaplan was first introduced to modern conservation efforts through the book "Jaguar" written by Alan Rabinowitz, a wildlife biologist, whose aspiring to build the first jaguar preserve in Belize. The wealthy philanthropist has already finalized his plans with the Wildlife Conservation Society for Project Leonardo will study the lions of Africa.

The article offers information on the 1990 meeting of the American Society of Zoologists in the U.S. The meeting featured the divisional symposium and workshops, including neuroendocrine strategies in a tropical environment, mechanism of mate choice and the evolution of viviparity in vertebrates. It also featured the society sponsored symposium and refresher courses, special sessions and exhibits.
