Female Papilio zelicaon in unlike populations show a hateful frequency of 1.2-1.ix matings, with a maximum of three. Mating frequency increases with female age. No seasonal or latitudinal mating frequency differences were discovered merely mating frequency was significantly greater in females from montane populations compared to lowland females. This difference was interpreted as resulting from increased mating frequency of selected males in “hilltop” areas leading to sperm/accessory gland depletion and rapid return of sexual receptivity in females mated to such males. Use of sperm from the terminal male in a mating sequence (sperm deportation) occurred in a double-mated female using a red-eyed mutant equally a genetic marking. Females mated to mature males laid more ova than those paired with immature males, while no differences were noted between the latter grouping and virgin females. Oviposition appears to exist influenced more by sperm quantity and/or accessory gland secretion than by physical presence of the spermatophore. Rapid multiple mating past males leads to smaller spermatophores deficient in sperm. Sperm is produced continuously at a compatible rate during the male person’s life whereas production charge per unit of accessory gland secretions decreases with male age. At least 40-fifty% of males less than 12 hr old are incapable of insemination of females. Male mating power (related to variance and duration of copulation) is low from 0-12 hr, peaks at age 2-8 days, so gradually declines. Extended copulation occurred in immature and one-time males and in 2d matings of rapid mating sequences. This was regarded as permitting sperm/accessory fluids to be produced and transferred in copulo while allowing depleted or young males to exploit mating opportunities.

Journal Information

The American Midland Naturalist has been published for 90 years by the University of Notre Dame. The connotations of Midland and Naturalist accept broadened and its geographic coverage now includes North America with occasional manufactures from other continents. The old image of naturalist has inverse and the journal publishes what Charles Elton aptly termed “scientific natural history” including field and experimental biology. Its significance and latitude of coverage are evident in that the American Midland Naturalist is among the most often cited journals in publications on ecology, mammalogy, herpetology, ornithology, ichthyology, parasitology, aquatic and invertebrate biology and other biological disciplines.

Publisher Information

Simultaneously an international center for Catholic thought, a teaching-focused liberal arts higher, and a dynamic hub for enquiry and scholarship, the College of Arts and Letters at the Academy of Notre Dame provides its students with an education that fuels their passion for learning while preparing them to make a departure in the world. The largest and oldest college in the university, Arts and Letters houses the divisions of the arts, humanities, and social sciences. Information technology encompasses 21 departments, more than 40 undergraduate and graduate caste programs, and a variety of interdisciplinary centers. Approximately 2,500 undergraduates and 750 graduate students pursue degrees through Arts and Letters programs; students from throughout Notre Dame enroll in thought-provoking Arts and Letters courses.
