Evolution of Seasonal Adaptations and Life History Traits in , Response to Diverse Selective Pressur synchronized with the seasonal presence of energy resources, mates, and favorable physical conditions. Also, the seasonal occurrence of vulnerable stages must be timed to avoid periods of physical extremes and periods when parasites, predators, and competitors occur at high densities. In a seasonal

The Prophecies of Parthenogenesis Undoubtedly, the most celebrated case of a virgin birth is that given in Matthew 1, 19–25: the account of the birth of Jesus Christ. Whether or not one accepts this account literally, one can still legitimately ask the question: Why is this account of a virgin birth contained in Matthew? Most peopl

Competition and Adaptation among Diploid and Polyploid Clones of Unisexual Fishes upon during times of environmental change. Attempts to evaluate the importance of variation, either in the production of heterosis or as adaptive polymorphisms in homogeneous, heterogeneous, or fluctuating environments, are generally confounded by two major problems: (1) identifying the forces of s

The Evolution of Life Spanng to Cole, “The total life history pattern of a species has meaning in terms of its ability to survive and ecologists should attempt to interpret these meanings.” The interpretational method he proposed and used was “to compute the characteristics of the future hypothetical population by assuming a

Life History Variation in Dioecious Plant Populations: A Case Study of ,pecies have shown that sexual dimorphism influences almost every aspect of their ecology and evolution (e.g., Bartholemew 1970, Feduccia and Slaughter 1974, Jackson 1970, Morse 1968). Although perhaps not so conspicuous for plant species, sexual dimorphism can have far-reaching effects on their biol

Phenotypic and Genetic Covariance Structure in Milkweed Bug Life History Traitsbility is caused by gene differences among individuals, changes in population growth differ among genotypes. Gene frequencies will change at loci with effects on life history traits, and selection and microevolution of life history traits should occur. However, if many life history characteristics v
