Preventive Intervention Research,related, and (2) both are correlated with the ecology of a species. A comparison of early ontogenies of logperch (.), rainbow darter (.), and fantail darter .) confirmed these premises, and provided possible explanations for diversity within the Etheostomatini. Young logperch have limited vitelline

A comparison of data from localities where all species were collected with localities where a one of the five species was absent suggests some degree of habitat disp

In Bayou Sara, the reproductive season extended from late March through April and possibly into June. Males and females were sexually mature in their first year. Counts of unovulated mature ova ranged from 1
