Strategic mowing of roadside milkweeds increases monarch butterfly oviposition

Global Ecology and Conservation, 2019
The eastern North American migratory population of monarch butterflies (Danaus plexippus) has declined precipitously due, in part, to the widespread decline of its obligate host plant, milkweed (Asclepias spp.). Linear right-of-ways (e.g.

Distance Diminishes the Effect of Deltamethrin Exposure on the Monarch Butterfly, Danaus plexippus [PDF]

Journal of the American Mosquito Control Association, 2020
ABSTRACT The monarch butterfly, Danaus plexippus (Lepidoptera: Nymphalidae), is threatened by substantial loss of habitat, extreme weather events linked to global climate change, and nontarget impacts of broad-spectrum insecticides. To investigate the impact of chronic ingestion of pyrethroids on monarchs, wild-type Florida D.

Western Monarch Population Plummets: Status, Probable Causes, and Recommended Conservation Actions

Frontiers in Ecology and Evolution, 2019
Western monarch butterflies dropped by ~97% of their average historic abundance between the 1980s and mid-2010s. In winter 2018–2019, the population plummeted even farther, to fewer than 30,000 monarchs, which represents a single year drop of 86% and a ...

Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

Insect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

Population genetic analysis of the endangered Mottled Duskywing butterfly (Erynnis martialis) informs species reintroduction

Insect Conservation and Diversity, EarlyView.
Mottled Duskywing (Erynnis martialis) populations had moderate levels of genetic diversity at microsatellites with expected heterozygosity ranging from 0.43 to 0.58, and populations more than 10 km apart were differentiated from one another. Weak patterns of isolation by distance and low effective population sizes suggest that all but the largest ...

Hierarchy and Scale Influence the Western Monarch Butterfly Overwintering Microclimate

Frontiers in Conservation Science, 2022
Migratory species are expected to demonstrate habitat selection that occurs at multiple spatial and temporal scales. Western monarch butterflies migrate seasonally to overwintering groves at geographically predictable locations along the coast of ...

Dispersal mediates metapopulation response to local and regional stressors

Insect Conservation and Diversity, EarlyView.
A feature of recent insect declines is that widespread, formerly common species are among the worst affected. We designed a metapopulation simulation to ask how dispersal capability interacts with landscape and population stressors that act at different spatial scales.

Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics

Journal of Fish Biology, EarlyView.
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,
