Assessing Role of Major Drivers in Recent Decline of Monarch Butterfly Population in North America

open access: yesFrontiers in Environmental Science, 2018
Monarch (Danaus plexippus L.) is a long distance migratory species of butterfly in North America that has experienced population declines in recent years. Several interacting factors have been postulated to contribute to this decline.

Estimating Overwintering Monarch Butterfly Populations Using Terrestrial LiDAR Scanning

open access: yesFrontiers in Ecology and Evolution, 2019
Concerns about the state of decline of the North American monarch butterfly (Danaus plexippus) have prompted their consideration for listing under the Endangered Species Act. Data suggest a substantial decline (> 80%) in overwintering numbers for both

Spatial Synchrony of Monarch Butterflies [PDF]

open access: yesThe American Midland Naturalist, 2006
I examined spatial synchrony in populations of monarch butterflies (Danaus plexippus) during the summer breeding season across North America and while overwintering along the Pacific Coast. Spatial synchrony was observed in all analyses, but was particularly great among eastern summer populations and among overwintering populations on the Pacific Coast.

Monarch Butterfly Conservation Through the Social Lens: Eliciting Public Preferences for Management Strategies Across Transboundary Nations

open access: yesFrontiers in Ecology and Evolution, 2019
The monarch butterfly (Danaus plexippus), an iconic species that migrates annually across North America, has steeply declined in numbers over the past decade.

Collecting \u3ci\u3eNeocurtilla Hexadactyla\u3c/i\u3e, the Northern Mole Cricket (Orthoptera: Gryllidae), in Iowa [PDF]

open access: yes, 2017
(excerpt) The northern mole cricket, Neocurtilla hexadactyla (Perty), is a common insect that is infrequently collected perhaps owing to its burrowing and nocturnal habits.

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

Size of the Canadian Breeding Population of Monarch Butterflies Is Driven by Factors Acting During Spring Migration and Recolonization

open access: yesFrontiers in Ecology and Evolution, 2019
The eastern North American monarch butterfly population shows a long-term population decline. While it is hypothesized that forest loss on the wintering grounds and milkweed loss throughout the breeding range are responsible for the observed decline ...

Warming‐Mediated Decreases in Nectar Quality Translate Into Lower Energy Reserves of the Monarch Butterfly (Danaus plexippus)

open access: yesGlobal Change Biology Communications, EarlyView.
Warming caused a significant decrease in monarch fat mass, likely due to an observed reduction in sucrose concentration caused by warming of the nectar. Since sucrose fuels fall migration and overwintering, our results suggest climate warming may reduce migration success and overwinter survival.
