Avocado Cover Expansion in the Monarch Butterfly Biosphere Reserve, Central Mexico

open access: yesConservation, 2021
Avocado cultivation has reduced the extent of forest ecosystems in central Mexico, even in natural protected areas such as the Monarch Butterfly Biosphere Reserve (MBBR) where information on the extent and expansion dynamics of avocado cover is scant ...

Spatial metabolomics reveal divergent cardenolide processing in the monarch (Danaus plexippus) and the common crow butterfly (Euploea core)

open access: yesMolecular Ecology Resources, 2023
Although being famous for sequestering milkweed cardenolides, the mechanism of sequestration and where cardenolides are localized in caterpillars of the monarch butterfly (Danaus plexippus, Lepidoptera: Danaini) is still unknown.

Polarized Light Helps Monarch Butterflies Navigate [PDF]

open access: yesCurrent Biology, 2004
During their spectacular migratory journey in the fall, North American monarch butterflies (Danaus plexippus) use a time-compensated sun compass to help them navigate to their overwintering sites in central Mexico. One feature of the sun compass mechanism not fully explored in monarchs is the sunlight-dependent parameters used to navigate.

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 ...

Density-dependence in the declining population of the monarch butterfly. [PDF]

open access: yesSci Rep, 2017
AbstractThe Eastern monarch butterfly population has significantly declined over the last two decades creating growing concerns around its conservation status. Here, we showed that the overwintering population exhibited a negative density-dependence (i.e.

The physiology of movement [PDF]

open access: yes, 2020
Movement, from foraging to migration, is known to be under the influence of the environment. The translation of environmental cues to individual movement decision making is determined by an individual's internal state and anticipated to balance costs and

A case study of a conservation flagship species: the monarch butterfly

open access: yesBiodiversity and Conservation, 2021
What makes a flagship species effective in engaging conservation donors? Large, charismatic mammals are typically selected as ambassadors, but a few studies suggest butterflies—and monarchs in particular—may be even more appealing.

Returning neighbors: eastern wild turkey (Meleagris gallopavo silvestris) occupancy in an urban landscape

open access: yesThe Journal of Wildlife Management, EarlyView.
We found that urban wild turkey had a higher probability of occupying a site if it was farther from roads and trails, closer to water, had more available habitat at finer spatial scales, or had lower mean tree height at larger spatial scales Abstract Once extirpated from most of its range because of overharvest and habitat loss in the early 1900s, the ...

Making Learning Personally Relevant: Sensemaking Assets Used in Families' Discussions While Using a Pollinator‐Focused Mobile Augmented Reality App

open access: yesScience Education, EarlyView.
ABSTRACT This study seeks to better understand the unique sensemaking assets that rural families weave into their outdoor learning experience while using a location‐based mobile app focused on healthy habitats for solitary bees. The project included mobile augmented reality (AR) technologies, which are increasingly used as educational tools at informal
