Complete mitochondrial genome recovered from the gut metagenome of overwintering monarch butterflies, Danaus plexippus (L.) (Lepidoptera: Nymphalidae, Danainae).
We present a 15,314 bp mitochondrial genome (mitogenome) sequence from monarch butterflies overwintering in Mexico. The complete mitogenome was generated by next generation sequencing techniques and was reconstructed by iterative assembly of reads from a metagenomic study of pooled butterfly gut DNA. The mitogenome codes for 13 putative protein coding genes, 22 tRNA genes, the large and small r...
متن کاملSperm 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 کاملEffects of Duration and Timing of Heat Stress on Monarch Butterfly (Danaus plexippus) (Lepidoptera: Nymphalidae) Development
Exposure to temperatures above 29?C has been shown to be detrimental to the de velopment of Monarch Butterfly (Danaus plexippus L.) (Lepidoptera: Nymphalidae) larvae, while it has been assumed that temperatures above 33? are lethal. However, the details of larval sensitiv ity to high temperatures are not clearly understood. We examined the effects of different lengths and timing of high-tempera...
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 کاملEffects of the protozoan parasite ophryocystis elektroscirrha on the fitness of monarch butterflies (Danaus plexippus)
We evaluated the effects of the protozoan parasite Ophryocystis elektroscirrha on the survival and reproduction of monarch butterflies. Because larvae in natural populations are likely to experience a wide range of natural parasite population densities, we examined the effects of increasing spore density (0, 10, 100, or 1000 spores per larva) on host fitness. Parasites had little effect on mona...
