Computer tools for addressing these problems include x,y digitizing devices interfaced to computers and interactive computer graphics systems. General computer algorithms now exist for 3-D reconstruction of schools given any two 2-D views such as photographs.

J. Marie Hardwick,Gary Ketner,Rollie J. Clemime. This coordinate development has also been seen in the laboratory. We hypothesize that juveniles resembling each other experience fewer aggressive responses from males than do juveniles without ‘look-alikes’, because of habituation of aggression. This would decrease social inhibition and permit their synchronous development.

Reproductive tactics of the Asian cichlids of the genus , in Sri Lanka,ge during nesting and nest site selection was determined mainly by factors favoring offspring survival. Biparental care is exhibited by both species. One member of an orange chromide pair stands guard over offspring while the other leaves the territory to forage — their roles are reversed every few

Facultative schooling behavior in the spottail shiner (,): possible costs and benefits,flee from predators, thereby gaining time and energy for feeding and other activities. These predictions were examined in the field (Veronica Lake, northwestern Ontario) using a facultative schooling species, the spottail shiner (.). Schools of various sizes ‘a(chǎn)ttacked’ with a fish predator model had
