Reproductive strategies of Tribolium flour beetles
Although, beetles of the genus Tribolium first evolved as saprophylic insects, they have adapted to the stored products environment for several thousand years. In this study reproductive strategies are described for eight species of Tribolium that are known to occur in this environment. Experiments were conducted under the same conditions for every species, and several life history traits, incl...
متن کاملModeling Populations of Flour Beetles
Mathematical models can be used to describe and predict the complex dynamics of biological phenomena such as animal populations. There is a trade-off between the amount of mathematical and biological complexity one can include in a model; fewer simplifications lead to a more biologically accurate model, but may come at the cost of adding dimensions or parameters. This increases the difficulty o...
متن کاملNew and emended descriptions of gregarines from flour beetles (Tribolium spp. and Palorus subdepressus: Coleoptera, Tenebrionidae).
The following new gregarine taxa are described from larvae of flour beetles (Coleoptera: Tenebrionidae): Awrygregarina billmani, n. gen., n. sp., from Tribolium brevicornis; Gregarina cloptoni, n. sp., from Tribolium freemani; Gregarina confusa, n. sp., from Tribolilum confusum; and Gregarina palori, n. sp., from Palorus subdepressus. In addition, the description of Gregarina minuta Ishii, 1914...
متن کاملAn integrative view of sexual selection in Tribolium flour beetles.
Sexual selection is a major force driving the evolution of diverse reproductive traits. This evolutionary process is based on individual reproductive advantages that arise either through intrasexual competition or through intersexual choice and conflict. While classical studies of sexual selection focused mainly on differences in male mating success, more recent work has focused on the differen...
متن کاملAn Experimental Test of the Relationship between Genetic Variation and Environmental Variation in Tribolium Flour Beetles.
The hypothesis that a component of genetic variation for polygenic fitness traits is maintained by environmental heterogeneity was tested using an experimental system involving two species of flour beetles, Tribolium castaneum and T. confusum. Replicated populations of each species from a number of environmental treatments were analyzed for various fitness components following almost 60 generat...
