Monarch butterfly optimization
Neural Computing and Applications, 2015In nature, the eastern North American monarch population is known for its southward migration during the late summer/autumn from the northern USA and southern Canada to Mexico, covering thousands of miles. By simplifying and idealizing the migration of monarch butterflies, a new kind of nature-inspired metaheuristic algorithm, called monarch butterfly ...

Palatability dynamics of cardenolides in the monarch butterfly [PDF]
Nature, 1974 THE adaptive strategy of sequestering cardiac glycosides from milkweed plants (Asclepiadaceae and Apocynaceae) has evolved in several taxa of insects1. Since these cardenolides elicit vomiting following ingestion, birds learn to avoid the insects on sight after one or more emetic experiences2.

The monarch butterfly in Mexico: a conservation model
Current Opinion in Insect Science, 2023Each fall, millions of monarch butterflies (Danaus plexippus L.) travel from Canada and the United States to overwinter in Mexico and California. In 2022, the IUCN listed migratory monarchs as endangered because of their population decline. The main accepted drivers are widespread use of herbicides, effects of climate, and land use change that causes ...

The case of the monarch butterfly: a verdict is returned [PDF]
Trends in Genetics, 2002 A publication reporting the harmful effects on the monarch butterfly of maize genetically modified to express insecticidal delta-endotoxins from the soil bacterium Bacillus thuringiensis (Bt) caused much public interest. A series of ecologically based studies were subsequently carried out to evaluate rigorously the impact of pollen from such crops and ...

Inbreeding depression in monarch butterflies
Journal of Insect Conservation, 2016Monarch butterflies and their unique system of multigenerational migration have long fascinated the public, and concerns for the fate of this charismatic insect have grown due to the consistent declines in overwintering colony size over the last 20 years.

Effect of mating on Monarch butterfly oogenesis
Experientia, 1977Oogenesis ceases in virgin Monarch butterflies at about 10 days posteclosion, but an enhanced production of mature oocytes occurs after mating. Juvenile hormone injections into virgins, and allatectomies of mated females, indicate that the observed fluctuations in oogenesis are due to periods of corpora allata activity and inactivity.

Tracking climate impacts on the migratory monarch butterfly [PDF]
Global Change Biology, 2012 AbstractUnderstanding the impacts of climate on migratory species is complicated by the fact that these species travel through several climates that may be changing in diverse ways throughout their complete migratory cycle. Most studies are not designed to tease out the direct and indirect effects of climate at various stages along the migration route.
