Studies on the autecology of Myriophyllum aquaticum in the South-Western Cape Province
Aquatic macrophytes are an integral part of any freshwater ecosystem. In addition to being primary producers, they assist in nutrient circulation and provide shelter and spawning areas for many other forms of associated animal life (Nichols and Keeney, 1973; De Marte and Hartman, 1974).

The autecology of the adult horn fly, Haematobia irritans (L.), (Diptera: Muscidae) on dairy cattle
A preliminary experiment was conducted during the horn fly season at Blacksburg, Virginia from May through September, 1959, to determine the relationship of weather conditions to horn fly populations on 3 breeds of dairy heifers. Daily records of the fly populations on 10 animals selected at random …
