Jackal Woman: Exploring the World of Jackals Take heart, fans of Wile E. Coyote and other hard-working scavengers -- Patricia Moehlman defends such creatures. Formerly a devotee of chimp woman Jane Goodall, Moehlman spent years on the Serengeti watching the silver-backed and golden jackals. Before publishing her book, the researcher published widely in books, journals and popular magazines such as National Geographic. Jackals, she finds, are not opportunistic scroungers that eat the rotting scraps left by better hunters; they're clever and brave predators in their own right. She brings stories of her favorite creatures, and slides showing their exploits, as part of the Houston Zoo's 1993-94 lecture series. Gate 5 opens at 6:30, presentation 7 p.m. Houston Zoological Gardens, Brown Education Center, Hermann Park, 529-2632. $8.
