“…Extreme weather events can reduce moth populations by up to 90%, but many populations are dynamic entities that are able to cope with extreme weather events (Greco et al, 2018). As of summer 2017, the remaining number of Poweshiek skipperlings across the four occupied Michigan sites was estimated to be around 231 individuals (Belitz et al, 2019). With populations this small, a stochastic weather event could cause local extinctions.…”

“…Overwintering Poweshiek skipperlings do not make shelters like many other skipper species and remain exposed at the base of grasses through winter, potentially leaving Poweshiek skipperling vulnerable to extreme weather conditions, dormant season fire, and other disturbances such as cattle grazing and pesticide drift (Runquist & Heimpel, 2017). Primary nectar sources of Poweshiek skipperling include Rudbeckia hirta, Dasiphora fruticosa, Echinacea angustifolia, and Solidago ptarmicoides (Swengel & Swengel, 1999;Semmler, 2010;Cuthrell & Slaughter, 2012;Belitz et al, 2019). Female Poweshiek skipperlings have been documented ovipositing on a variety of graminoid species, with larvae and ovipositing females appearing to prefer fine, threadlike structures (Selby, 2005;Belitz et al, 2019).…”

Poweshiek skipperlings were historically documented in habitat that included wet-mesic prairie, dry prairie and prairie fen (Selby, 2005).…”

1. The Poweshiek skipperling [Oarisma poweshiek (Parker, 1870; Lepidoptera: Hesperiidae)] is a federally endangered butterfly that was historically common in prairies of the upper Midwestern United States and Southern Manitoba, Canada. Rapid declines over the last 20 years have reduced the population numbers to four verified extant sites. The causes of Poweshiek skipperling decline are unknown. 2. We aggregated all known Poweshiek skipperling occurrence records to examine the spatiotemporal patterns of Poweshiek skipperling decline. Ecological niche models were developed for five time frames (1985, 1990, 1995, 2000 and 2005) and three spatial extents (eastern occupied range, western occupied range and total occupied range). We used a backward elimination method to investigate the effects of climate and land use on the ecological niche of Poweshiek skipperling. 3. Predictors of occurrence changed over time and across the geographical extent of Poweshiek skipperling. Land use covariates were retained in east models. In the west and total extent, climate variables contributed the most to model predictive power for the 1985, 1990 and 1995 models; land use variables contributed the most to model predictive power in the 2000 and 2005 models. 4. During the rapid decline in Poweshiek skipperling population numbers occurring at the turn of the century, probability of Poweshiek skipperling presence was being driven by proportion of natural land cover and distance to nearest grassland/wetland. Our results suggest that these land use variables are important landscape‐level variables to consider when developing risk assessments of extant populations and potential reintroduction sites.

“…Butterfly surveys-Poweshiek skipperling are small butterflies with a wingspan of approximately 3 cm. They emerge as flying, reproductive adults from late June to mid July (i.e., the flight period) (Selby, 2005;Belitz et al, 2019). They were abundant until as recently as the mid-1990s, with hundreds of populations, each population consisting of hundreds of individuals, in prairies and prairie fens throughout the upper Midwest (Selby, 2005).…”

“…They were abundant until as recently as the mid-1990s, with hundreds of populations, each population consisting of hundreds of individuals, in prairies and prairie fens throughout the upper Midwest (Selby, 2005). Over the past 20 years, their numbers dropped dramatically to only six extant sites worldwide, and their combined abundance in four Michigan prairie fens was estimated to be fewer than 400 adult individuals (Belitz et al, 2019).…”

PremiseHeterogeneity of biodiversity data from the collections, research, and management communities presents challenges for data findability, accessibility, interoperability, and reusability. Workflows designed with data collection, standards, dissemination, and reuse in mind will generate better information across geopolitical, administrative, and institutional boundaries. Here, we present our data workflow as a case study of how we collected, shared, and used data from multiple sources.MethodsIn 2012, we initiated the collection of biodiversity data relating to Michigan prairie fens, including data on plant communities and the federally endangered Poweshiek skipperling (Oarisma poweshiek).ResultsOver 23,000 occurrence records were compiled in a database following Darwin Core standards. The records were linked with media and biological, chemical, and geometric measurements. We published the data as Global Biodiversity Information Facility data sets and in Symbiota SEINet portals.DiscussionWe highlight data collection techniques that optimized transcription time, including the use of predetermined and controlled vocabulary, Darwin Core terms, and data dictionaries. The validity and longevity of our data were supported by voucher specimens, metadata with measurement records, and published manuscripts detailing methods and data sets. Key to our data dissemination was cooperation among partners and the utilization of dynamic tools. To increase data interoperability, we need flexible and customizable data collection templates, coding, and enhanced communication among communities using biodiversity data.
