Introduction
Daphnia pulex Leydig (Crustacea, Cladocera) is a common component of the zooplankton of freshwater lakes and ponds. Its importance in the aquatic trophic structure as food for small fish has long been recognized.
Typical populations of daphnia consist almost exclusively of females. Under favorable conditions this situation is perpetuated by parthenogenetic reproduction. Eggs produced in this manner are referred to as parthenogenetic or summer eggs. When stressed by falling temperatures, drought, overpopulation, or starvation, populations shift to sexual.reproduction. Parthenogenetic eggs are produced which develop into males. Other eggs known as ephippial or winter eggs are also produced, which after …

Vegetational Communities On An Abandoned Farm In Van Buren County, Michigan, Larry G. Visser
Masters Theses
Introduction
Several studies have been made of xeric forests in southern Michigan which have developed through secondary succession following the cutting of the presettlement vegetation. Brewer et al. (1973) described such an area in Allegan County, Michigan which was dominated by presettlement pine and is now dominated by oak. The oak forests of the Harvey Ott Preserve in Calhoun County, Michigan have been described by Catana (1967). Studies of the oak forests in the Haven Hill area in southeastern Michigan have been made by Thompson (1953). In addition to these studies of xeric forests in southern Michigan, extensive studies of …
