Population dynamics and drivers of the eastern monarch (Danaus plexippus) across its full annual cycle: a cross-scale synthesis of a model migratory species
The monarch butterfly is arguably the best known butterfly species throughout its global
range. Declines in the size of the overwintering colonies in Mexico have sparked …

Long‐term surveys support declines in early season forest plants used by bumblebees
Populations of bumblebees and other pollinators have declined over the past several
decades due to numerous threats, including habitat loss and degradation. However, we can …

Larval pesticide exposure impacts monarch butterfly performance
The long-term decline of monarch butterflies has been attributed to loss of their milkweed
(Asclepias sp.) host-plants after the introduction of herbicide-tolerant crops. However, recent …

A comparison of summer, fall and winter estimates of monarch population size before and after milkweed eradication from crop fields in North America
Measures of the area occupied by overwintering monarchs in México since the mid‐1990s
show a decline. Summer surveys of monarchs, however, do not show a similar decline. This …

Interpreting surveys to estimate the size of the monarch butterfly population: Pitfalls and prospects
To assess the change in the size of the eastern North American monarch butterfly summer
population, studies have used long-term data sets of counts of adult butterflies or eggs per …

Multiscale seasonal factors drive the size of winter monarch colonies
Monarch butterflies in eastern North America have declined by 84% on Mexican wintering
grounds since the observed peak in 1996. However, coarse-scale population indices from …

Local and cross‐seasonal associations of climate and land use with abundance of monarch butterflies Danaus plexippus
Quantifying how climate and land use factors drive population dynamics at regional scales is
complex because it depends on the extent of spatial and temporal synchrony among local …

Patterns and causes of oviposition in monarch butterflies: implications for milkweed restoration
Effective habitat restoration requires an understanding of species habitat preferences and
the associated mechanisms driving those preferences. We examined the patterns and …
