Monarch butterfly population decline in North America: identifying the threatening processes [PDF]

open access: yesRoyal Society Open Science, 2017
The monarch butterfly (Danaus plexippus) population in North America has sharply declined over the last two decades. Despite rising concern over the monarch butterfly's status, no comprehensive study of the factors driving this decline has been conducted.

The neurobiology of the Monarch butterfly compass.

open access: yesCurrent Opinion in Insect Science, 2023
Monarch butterflies (Danaus plexippus) have become a superb model system to unravel how the tiny insect brain controls an impressive navigation behavior, such as long-distance migration. Moreover, the ability to compare the neural substrate between migratory and nonmigratory Monarch butterflies provides us with an attractive model to specifically study

Demystifying Monarch Butterfly Migration [PDF]

open access: yesCurrent Biology, 2018
Every fall, millions of North American monarch butterflies undergo a stunning long-distance migration to reach their overwintering grounds in Mexico. Migration allows the butterflies to escape freezing temperatures and dying host plants, and reduces infections with a virulent parasite.

Neurobiology of Monarch Butterfly Migration [PDF]

open access: yesAnnual Review of Entomology, 2016
Studies of the migration of the eastern North American monarch butterfly (Danaus plexippus) have revealed mechanisms behind its navigation. The main orientation mechanism uses a time-compensated sun compass during both the migration south and the remigration north.

Neural representation of goal direction in the monarch butterfly brain

open access: yesbioRxiv, 2022
Neural processing of a navigational goal requires the continuous comparison between the current heading and the intended goal direction. While the neural basis underlying the current heading is well-studied in insects, the coding of the goal direction is
