Sperm precedence in monarch butterflies (Danaus plexippus)
We characterized sperm precedence in monarch butterflies (Danaus plexippus), using a series of experiments in which we manipulated male mating histories to vary spermatophore size and the number of sperm transferred. Several factors affected the outcome of sperm competition. There was a pattern of second-male sperm precedence, but second-male precedence was rarely complete, and several other fa...
متن کاملExperimental Examination of Intraspecific Density-Dependent Competition during the Breeding Period in Monarch Butterflies (Danaus plexippus)
A central goal of population ecology is to identify the factors that regulate population growth. Monarch butterflies (Danaus plexippus) in eastern North America re-colonize the breeding range over several generations that result in population densities that vary across space and time during the breeding season. We used laboratory experiments to measure the strength of density-dependent intraspe...
متن کاملIdentifying at Highway-Rail Grade Crossing Hotspots in Canada
This research presents a risk-based Hotspots identification model at highway-rail grade crossings in Canada. Two sets of models were developed to predict collision frequency and consequence at individual crossings. A two–dimensional graphic approach was adopted to combine these two models together to predict the risk at each crossing. Hotspots based on collision history tended to be widespread ...
متن کاملIteradensovirus from the Monarch Butterfly, Danaus plexippus plexippus
The 5,006-nucleotide (nt)-long genome of a new virus from monarch butterfly pupae was cloned and sequenced. It was flanked by inverted terminal repeats (ITRs) of 239 nt with 163-nt hairpins. The monosense genome with three open reading frames is typical of the genus Iteradensovirus in the subfamily Densovirinae of the family Parvoviridae.
متن کاملPhenology of Cold Hardiness in Reproductive and Migrant Monarch Butterflies (Danaus plexippus) in Southwest Ohio
We examined seasonal changes in the cold hardiness of summer reproductive and fall migrant cohorts of the monarch butterfly in southwest Ohio in 1994. Reproductive and migrant butterfl ies were distinguished on the basis of l ipid content and whether the female had mated. We compared crystall ization temperatures (the temperature at which ice forms inside the body) and the capacity to resist ch...
