During 1990–1997, we recorded 122 138 adult butterflies in transect surveys at 125 pine-oak barrens in northern Wisconsin and 106 tallgrass prairies in six midwestern states grouped into three prairie subregions. Before analysis, we classified the butterflies into three ecological subgroups: specialist of native herbaceous vegetation, grassland (widely occurring in native and degraded herbaceous vegetation), and generalist. We analyzed this dataset both by ecological subgroups and as total… 

Declines of prairie butterflies in the midwestern USA

It is indicated that tallgrass prairie specialist butterflies are not co-evolved with current fire regimes, and declines after preservation will likely continue unless the conservation approach changes to include consideration of individual species’ required resources and management tolerances.

The effects of ecological management on tallgrass prairie butterflies and their nectar sources

The Pollard walk line transect is the most frequently used technique for assessing the relative abundance of butterflies, but the abundance estimates it provides are vulnerable to biases due to

The butterfly fauna of Wisconsin bogs: lessons for conservation

Long-term vegetative consistency, as in bogs, is advised for conservation management of specialist butterflies in other fragmented vegetations.

Management regime and habitat response influence abundance of regal fritillary ( Speyeria idalia ) in tallgrass prairie

The >2,570,000-ha Flint Hills ecoregion of Kansas, USA, harbors the largest remaining contiguous tract of tallgrass prairie in North America, a unique system, as the remainder of North America’s

High and dry or sunk and dunked: lessons for tallgrass prairies from quaking bogs

Northern Wisconsin bogs provide a natural experiment on butterfly population occurrence in a naturally highly fragmented vegetation type, which may provide insight on conserving butterflies in

The bootstrap was found to be the best predictor of true richness of species richness and the design of future surveys would be facilitated if sampling fraction was routinely reported and examined in relation to sample completeness.

Bee community responses to a gradient of oak savanna restoration practices

Overall, oak savanna restoration by thinning and burning had positive effects on bee diversity, while burning alone only increased bee abundance, illustrating how restoration strategies that typically target plants have broader‐reaching biodiversity benefits.

Leaf Beetle (Coleoptera: Chrysomelidae) Biodiversity within Isolated Remnant Grasslands in Kentucky State Nature Preserves

The results demonstrate the importance of protected areas such as state nature preserves as refugia not only for known threatened or endangered plants and animals, but also for associated biota in little-studied groups, such as leaf beetles.

Impact of prescribed burning on endophytic insect communities of prairie perennials (Asteraceae: Silphium spp.)

It is suggested that sufficient numbers of endophytic insects survive burns in remains of Silphium to recolonize burned areas the following year, and even when a prairie remnant was completely incinerated, plant stems were recolonized by insects within one growing season.

Benefit of permanent non-fire refugia for Lepidoptera conservation in fire-managed sites

From the early 1990s through 2005, we conducted butterfly transect surveys annually at the same sites in three regions of Wisconsin. We compared specialist butterfly population indices at three sites



Comparisons of butterfly richness and abundance measures in prairie and barrens

Within a habitat type, site rankings based on total butterflies significantly tended to agree with site Rankings based on specialist butterflies, suggesting that site prioritization and management favouring specialist butterflies would also favour the overall butterfly fauna possible in the same habitat.

Co-occurrence of prairie and barrens butterflies: applications to ecosystem conservation

Abundance indices from transect surveys for species restricted to prairies and barrens were correlated to test the degree to which these species of conservation concern co-occur. In 56 pair-wise

Managing Species Diversity in Tallgrass Prairie: Assumptions and Implications

Conservation and restoration ecology efforts may conserve or restore a particular image of a community, a variety of plausible images, or maximum biological diversity. The choice is a policy decision

The effects on butterfly abundance of the management of uncropped edges of arable fields

The abundance of adults of most butterfly species was most closely associated with the abundance of flowers of key nectar source species, and stepwise multiple regression analyses on butterfly and plant data showed.

The effects of arable field margin management on the abundance and species richness of Araneae (spiders)

The extent to which management practices which benefit Araneae are compatible with both the management requirements for various other taxa, and the overriding constraint of effective pernicious weed control on field margins, is discussed.

Habitat associations of sympatric violet-feeding fritillaries (Euptoieta, Speyeria, Boloria) (Lepidoptera: Nymphalidae) in tallgrass prairie

At 106 tallgrass prairies in the midwestern USA, 18,055 individuals of six fritillary species (Lepidoptera: Nymphalidae) were counted and three of four testable fritilla y species significantly d positively correlated in abundance with one or more species of V ola (Vio­ laceae) (violets).

Grasshopper response to a 40-year experimental burning and mowing regime, with recommendations for invertebrate conservation management

Grasshopper responses to vegetation type, and to different burning and mowing practices, were site-specific, despite the close proximity of sites, suggesting that grasshopper assemblage composition is not entirely deterministic and depends on the trajectory of plant succession.
