Spatial Synchrony of Monarch Butterflies [PDF]
The 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.

Estimating Overwintering Monarch Butterfly Populations Using Terrestrial LiDAR Scanning
Frontiers 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

The Role of Modeling in Monarch Butterfly Research and Conservation
Frontiers in Ecology and Evolution, 2019 Models are an integral part of the scientific endeavor, whether they be conceptual, mathematical, statistical, or simulation models. Models of appropriate complexity facilitate comprehension and improve understanding of the variables driving system ...

Uptake and toxicity of clothianidin to monarch butterflies from milkweed consumption [PDF]
PeerJ, 2020 Recent concern for the adverse effects from neonicotinoid insecticides has centered on risk for insect pollinators in general and bees specifically. However, natural resource managers are also concerned about the risk of neonicotinoids to conservation ...

Monarch Butterfly Migration Moving into the Genetic Era. [PDF]
Trends Genet, 2020 The genetic architecture and neurogenetics of animal migration remain poorly understood. With a sequenced genome and the establishment of reverse genetic tools, the monarch butterfly has emerged as a promising model to uncover the genetic basis of migratory behavior and associated traits.

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

Navigational mechanisms of migrating monarch butterflies [PDF]
Trends in Neurosciences, 2010 Recent studies of the iconic fall migration of monarch butterflies have illuminated the mechanisms behind their southward navigation while using a time-compensated sun compass. Skylight cues, such as the sun itself and polarized light, are processed through both eyes and are probably integrated in the brain's central complex, the presumed site of the ...
