Where do Harris’ Checkerspots Lay their Eggs and what are the Consequences?
Where a female lays her eggs has strong implications for the survival of her offspring, an impetus that takes on particular significance for species...
-
Caterpillar movement mediates spatially local interactions and determines the relationship between population density and contact
BackgroundWhile interactions in nature are inherently local, ecological models often assume homogeneity across space, allowing for generalization...

Non-target effects of herbicides on the Zerene silverspot butterfly, a surrogate subspecies for the threatened Oregon silverspot butterfly
AbstractHerbicides are used as management tools to improve habitat for native plants and animals, but their application may also have harmful effects...

Mark-recapture study and habitat assessment for the northern metalmark butterfly, Calephelis borealis (Lepidoptera: Riodinidae)
BackgroundThe northern metalmark ( Calephelis borealis ), is an exceedingly local, globally rare butterfly that is declining across the Midwestern and...

Urban yards as potential conservation space: large, diverse gardens may be valuable resource patches for butterflies
Public and private flower gardens could be valuable for slowing pollinator decline in urbanized areas, as they can potentially provide crucial...
-
Novel host plant use by a specialist insect depends on geographic variation in both the host and herbivore species
Understanding the circumstances under which insect herbivores will adopt a novel host plant is a longstanding question in basic and applied ecology....
-
Seasonal Variation in Host Plant Chemistry Drives Sequestration in a Specialist Caterpillar
Sequestration of plant secondary metabolites by herbivores can vary across both host plant phenology and herbivore ontogeny, but few studies have...

Using structured decision making to guide habitat restoration for butterflies: a case study of Oregon silverspots
AbstractWhen making decisions about how to restore habitat for at-risk species, land managers must balance multiple competing objectives in the face...

Sequestered Caterpillar Chemical Defenses: From “Disgusting Morsels” to Model Systems
Caterpillars that sequester chemical defenses from their host plants are truly caught in the middle between their host plants and their enemies. On...

Characterizing urban butterfly populations: the case for purposive point-count surveys
Develo** effective butterfly monitoring strategies is key to understanding how butterflies interact with urban environments, and, in turn, to...

Effects of flight and food stress on energetics, reproduction, and lifespan in the butterfly Melitaea cinxia
Environmental change can have drastic effects on natural populations. To successfully predict such effects, we need to understand how species that...

The Effects of Nitrogen Enrichment on Low-Nutrient Environments: Insights from Studies of Serpentine Soil-Plant Relations
It is widely known that anthropogenic inputs, particularly from modern agriculture and fossil fuel combustion, are severely altering the nitrogen (N)...

Host Plant Effects on the Caterpillar Immune Response
Given the barrage of natural enemies that lepidopterans face during their larval stage, the immune response should provide reliable, effective...
-
Patchy range retractions in response to climate change and implications for terrestrial species conservation
ContextEfforts to adapt conservation to climate change often focus on facilitating range shifts to higher latitudes, by enhancing landscape capacity...
-
Weather anomalies more important than climate means in driving insect phenology
Studies of long-term trends in phenology often rely on climatic averages or accumulated heat, overlooking climate variability. Here we test the...

Feeding experience on hairy vetch induces a loss of host-specific adaptation to maize and changes in the gut microbiota communities of the fall armyworm
Develo** ecological control technologies against the fall armyworms (FAWs) is crucial. The ecological role of green manure crops has gained...
-
Factors Confronting a Shelter-Building Caterpillar at Spring Emergence
Weather often subjects overwintering small invertebrates to heavy losses and forces survivors emerging from the litter to respond quickly to achieve...
-
Viral Infection Induces Changes to the Metabolome, Immune Response and Development of a Generalist Insect Herbivore
Host plant consumption and pathogen infection commonly influence insect traits related to development and immunity, which are ultimately reflected in...

A Phylogenetic Approach to Conservation: Biodiversity and Ecosystem Functioning for a Changing Globe
As late as the sixteenth century, the world was a matrix of primarily wildlands. But due to technology development and population growth, humans...
