The data set contains raw data for pesticide (naled) residues on samplers collected after aerial applications over the National Key Deer Refuge in the Florida Keys, and biological response (cholinesterase activity in butterflies and mosquito mortality) for organisms co-located with the residue samplers.

Sawgrass (Cladium jamaicense) samples were collected from marshes on five different keys (Big Pine, Torch, Ramrod, Cudjoe, and Sugarloaf Keys) within National Key Deer Refuge in January and June of 2015 and analyzed for contamination by the mosquito control insecticide permethrin. Permethrin was detected on 17 of 57 samples collected in January while it was detected on 40 of 56 samples collected in June. The concentrations on samples collected in January (below detection to 16 ng/g ww) were lower than concentrations on samples collected in June (below detection to 57.7 ng/g).

Conclusions: Valleys are the only areas capable of sustaining sufficient habitat for the butterfly species, Weidemeyer's Admiral. Consequently, all other areas (i.e. plains, uplands, benches, escarpments, plateaus) were deemed unsuitable. Additionally, areas devoid of shrub cover did not meet the habitat requirements of this specialized species. Thresholds/Learnings: Synopsis: Two variables were selected to model potential habitat for the butterfly species, Weidemeyer's Admiral. Topographical features derived from the Agricultural Region of Alberta Soils Inventory Database (AGRASID) and percent shrub cover derived from the Native Prairie Vegetation Baseline Inventory developed by Alberta Environment were used to...
To define the faunal context within which local and regional resource management decisions are made, conservation of biological diversity requires an understanding of regional species occurrence patterns. Our study focused on the Southern Rocky Mountains of New Mexico and included the San Juan, the Sangre de Cristo, and the Jemez Mountains. Across this region, we quantified patterns of species richness and faunal diversity based on reported and predicted occurrences for birds, mammals, reptiles, amphibians, fish, and butterflies across this region. Specific hypotheses related to the origin and maintenance of observed diversity patterns were tested and interpreted based on their implication for biodiversity assessment...
A habitat-change model was used to compare past, present, and future land cover and management practices to assess potential impacts of alternative agricultural practices on wildlife in two agricultural watersheds, Walnut Creek and Buck Creek, in central Iowa, USA. This approach required a habitat map for each scenario based on soil type and land cover, a list of resident species, and an estimate of the suitability of each of 26 habitat classes for every species. Impact on wildlife was calculated from median percent change in habitat area relative to the present. Habitat classes with the highest species richness for native vertebrates were ungrazed riparian forest, upland forest and wet prairie. Differences in habitat...

A set of experiments was conducted to determine the dietary clothianidin exposures that cause prepupal mortality in the absence of other adverse effects. Monarch larvae were raised from hatch to pupae on clothianidin contaminated swamp milkweed plants. Larval growth, larval survival, and prepupal survival were monitored throughout the experiments in which the exposures ranged from 1.4 – 2,793.1 ng/g leaf. Exposures of 5.4 – 46.9 ng/g leaf resulted exclusively in prepupal mortality while higher exposures of 1,042.4 – 2,793.1 ng/g leaf resulted exclusively in larval mortality. An LC50 and LC10 of 37 and 6 ng/g, respectively, were estimated based on prepupal mortality.

Wild bee and butterfly samples were collected from the margins of agricultural fields located on five Conservation Areas in Missouri. In 2016 and 2017, samples were collected and composited by genera for a total of 90 samples. Samples were extracted via pressurized liquid extraction and solid phase extraction cleanup. Samples were analyzed for 168 pesticides and degradates using both gas and liquid chromatography-tandem mass spectrometry. Overall, 16 pesticides were detected. Pesticides detected in greater than 2% of the composite samples included: metolachlor (24%), tebuconazole (22%), atrazine (18%), imidacloprid desnitro (13%), bifenthrin (9%), flumetralin (9%), p,p’-DDD (6%), tebupirimfos (4%), fludioxonil (4%),...

Conclusions: The nature of the surrounding matrix contributes significantly to the degree of patch isolation; matrix modification may improve habitat connectivity and genetic distribution in fragmented landscapes. Thresholds/Learnings: Synopsis: This study challenges traditional assumptions about the uniform nature of the matrix, and the reliance on distance alone as an indicator of patch isolation, by testing whether the type of inter-patch matrix contributes significantly to patch isolation in butterfly populations. The author tracked the movement of six butterfly species between patches of meadow habitat through two natural matrix types (conifer forest and willow thicket). All taxa of butterflies studied responded...

Conclusions: Emigration rates are closely tied to edge structure. Low contrast edges promote edge permeability Thresholds/Learnings: Synopsis: The behavior of two butterfly species, one habitat specialist and one habitat generalist, were tracked at four prairie edges to determine the extent to which edge structure affects emigration. The specialist species responded strongly to all edges, and was particularly affected by edge density. The generalist species responded strongly only to high contrast edges. Emigration rates are closely tied to edge structure. Therefore, promoting low contrast edges in conservation planning may positively influence edge permeability and species richness in highly fragmented landscapes.

This dataset contains data of permethrin residues on adult mosquitoes and adult butterflies following their exposure to ultra-low volume (ULV) sprays containing permethrin. The dataset also contains toxicity information for permethrin; first for adult mosquitoes and adult butterflies following their exposure to the ULV sprays, and for adult mosquitoes exposed during toxicity tests to determine median lethal dose levels (LD50).
Wepresenttheresultsofarapidassessmentofbutterflydiversityinthe754haBeaverMeadows study area in Rocky Mountain National Park, Larimer County, Colorado. We measured butterfly species rich- ness and relative abundance as part of a landscape-scale investigation of diversity patterns involving sever- al groups of organisms. A stratified random sampling design was used to include replication in both rare and common vegetation types. We recorded 49 butterfly species from the twenty-four 0.1 ha plots that were sam- pled four times during June, July, and August 1996. Butterfly species richness, diversity, and uniqueness were highest in quaking aspen (Populus tremuloides Michaux) groves and wet meadows, which occupy only...
