Environment and Host Genetics Drive Infection Outcomes in a Butterfly Host, but Do Not Interact With Each Other. [PDF]
Ecol EvolThis study examined how host genetics and larval food plant environment influence parasite infection outcomes in monarch butterflies (Danaus plexippus) infected with the protozoan Ophryocystis elektroscirrha. We tested for genotype × environment interactions on infection status, infection burden, lifespan, and wing size.

Desert Milkweed (Asclepias erosa) as a Midsummer Resource for Arthropod Communities in the Great Basin Desert [PDF]
Ecol EvolBLURB FOR ETOC: In the Great Basin Desert, many plants senesce as heat and drought intensify in midsummer, potentially concentrating arthropods on the few species that remain physiologically active. We surveyed arthropods on desert milkweed (Asclepias erosa) during this period and recorded 1779 individuals representing 67 morphospecies across 41 plants;

Insects, 2019 Background: North American monarchs (Danaus plexippus) are well-known for their long-distance migrations; however, some monarchs within the migratory range have adopted a resident lifestyle and breed year-round at sites where tropical milkweed (Asclepias

Estimating Milkweed Abundance in Metropolitan Areas Under Existing and User-Defined Scenarios
Frontiers in Ecology and Evolution, 2019 Metropolitan areas play an undetermined role in supporting migratory monarch butterfly (Danaus plexippus) populations despite providing habitat areas rich with milkweed (Asclepias spp.), the obligate host plants for monarch larvae.

Journal of Natural Fibers, 2023 The use of natural fibers is a sustainable alternative for developing reinforced-polymer composites. It is believed that the seed flosses of common milkweed, Asclepias Syriraca, may be a promising reinforcing fiber given its uncommon hollow ...
