Eustrongylides and pesticide levels in a great blue heron shot in Wisconsin
The parasitic roundworm, Eustrongylides ignotus Jagersk, has been known to cause mortality and morbidity in members of the heron family in the eastern states of North America. To date no previous records exist for this nematode in Wisconsin. Even though eustrongylidiosis was first detected in the District of Columbia in 1926 by Chapin (1926), it was not until 1976 that this parasite was found in the midwest, in central Indiana (Winterfield and Kazacos 1977). The purpose of this report is to document the occurrence of this nematode even further westward in Wisconsin, and to show the debilitating effect it can have on herons.

Book review: Birds of Wyoming
"Wyoming may very well be one of the least birded states in the U.S." So begins this book, underscoring the challenges in summarizing existing knowledge for a state that falls next to last in human population density. Despite the relative dearth of "binoculars on the ground," especially in more remote areas of the state, the book offers a thorough compilation of relevant details. Much of this information is not readily accessible from other sources, and this book dispenses essential information in a very usable format. Review info: Birds of Wyoming . By Douglas W.

Microhabitat selection by bobcats in the badlands and Black Hills of South Dakota, USA: a comparison of Prairie and forested habitats
An understanding of habitat selection is important for management of wildlife species. Although bobcat (Lynx rufus) resource selection has been addressed in many regions of the United States, little work has been conducted in the Northern Great Plains. From 2006–2008 we captured and radiocollared 20 bobcats in the Badlands (n = 10) and Black Hills (n = 10) regions of South Dakota. During the summers of 2008 and 2009 we collected habitat measurements at 349 (176 Badlands, 176 Black Hills) bobcat locations and 321 (148 Badlands, 173 Black Hills) random sites. Microhabitat characteristics at bobcat use sites varied with region (P < 0.001) and sex of bobcat (P < 0.001). Percent slope, shrub, low cover, medium cover, and total cover were greater (P ≤ 0.017) at bobcat locations in the Black Hills than in the Badlands whereas distance to drainage was greater (P < 0.001) at locations in the Badlands than in the Black Hills. In the Badlands, male bobcat locations were closer (P ≤ 0.002) to prairie dog towns and drainages and had greater (P < 0.05) percent forbs and forb height than random sites, whereas females were closer to badland formations (P < 0.001) than random sites. In the Black Hills, male locations were at greater elevation (P < 0.001) and female locations were characterized by greater (P ≤ 0.02) grass height, shrub height, low cover, and total cover than random sites. Logistic regression indicated that microhabitat selection was similar between study areas; odds ratios indicated that odds of bobcat use increased by 0.998 (95% CI = 0.997–0.999) per 1 m increase in distance to drainage, 0.986 (95% CI = 0.978–0.993) per 1.0% increase in grass cover, by 1.024 (95% CI = 1.011–1.036) per 1 cm increase in grass height, by 1.013 (95% CI = 1.003–1.024) per 1% increase in forb cover, and by 1.028 (95% CI = 1.017–1.039) per 1% increase in medium cover. Our results were similar to other bobcat microhabitat selection studies, where bobcat relocations were associated with understory vegetation, drainages, and rugged terrain. These results identify the adaptability of the species to meet life history requirements in a variety of landscapes, and provide insight to how land use requirements vary within regional and management boundaries.

Habitat selection by female swift foxes (Vulpes velox) during the pup-rearing season
The swift fox (Vulpes velox) was historically distributed in western South Dakota including the region surrounding Badlands National Park (BNP). The species declined during the mid-1800s, largely due to habitat loss and poisoning targeted at wolves (Canis lupis) and coyotes (C. latrans). Only a small population of swift foxes near Ardmore, South Dakota persisted. In 2003, an introduction program was initiated at BNP with swift foxes translocated from Colorado and Wyoming. We report on habitat use by female swift foxes during the pup-rearing season (May–July) in 2009. Analyses of location data from 13 radiomarked female foxes indicated disproportional use ( P < 0.001) of some habitats relative to their availability within swift fox home ranges. Swift foxes used grassland ( Ŷ = 1.01), sparse vegetation ( Ŷ = 1.43) and prairie dog towns ( Ŷ = 1.18) in proportion to their availability, whereas they were less likely to use woodland ( Ŷ = 0.00), shrubland ( Ŷ = 0.14), pasture/agricultural-land ( Ŷ = 0.25) and development ( Ŷ = 0.16) relative to availability. Swift foxes typically are located in habitats that provide greater visibility, such as shortgrass prairie and areas with sparse vegetation; which allow detection of approaching coyotes (e.g., primary predator of swift foxes).

Notes on the distribution of eastern woodrats and hispid cotton rats in south-central Nebraska
The eastern woodrat ( Neotoma floridana ) and hispid cotton rat ( Sigmodon hispidus ) reach distributional limits in southern Nebraska (Jones 1964, Farney 1975). In the last half century, both species have expanded their distributional ranges in the region (Kugler and Geluso 2009, Wright et al. 2010). Herein, we report new localities of occurrence for both species that extend known distributional boundaries in south-central Nebraska beyond those reported by Kugler and Geluso (2009) and Wright et al. (2010).

Book review: Sandhill and whooping cranes: Ancient voices over America's wetlands
Paul Johnsgard has long been captivated by wild cranes and their unique vocalizations, courtship dances, and wide-ranging migrations. As a scientist and an admirer, Johnsgard has watched their migrations and behaviors for decades as hundreds of thousands of cranes staged each spring by the central Platte River, not far from his home in Lincoln, Nebraska. As an artist, he has skilfully captured their courtship dances and other behaviours in his exceptional line drawings. And, as an author, he has written extensively on their ecology in three earlier books: Cranes of the World (1983), Those of the Gray Wind: the Sandhill Crane (1986), and Crane Music: a Natural History of Cranes (1991). Much has happened relative to North American cranes in the 20 years since Johnsgard published Crane Music , including increased crane abundance in many areas and the completion of multiple studies on crane ecology and conservation. This new crane book serves as an update to Crane Music and provides the reader with many useful resources for observing and learning about cranes.

Book review: The Tallgrass Prairie Center guide to seed and seedling identification in the Upper Midwest
This attractive, slim volume provides a wonderful introduction to a neglected aspect of prairie plant identification: seeds and seedlings. Williams, and the illustrator Brent Butler, take the mystery out of dichotomous keys with clear descriptions, vivid illustrations, and abundant photographs of characteristics that distinguish common, tallgrass prairie, seedlings. A botanical novice should have no problem using this book to identify seedlings in their prairie garden – presuming that they planted only those species included in the book (more on that later).

Use of seeded exotic grasslands by wintering birds
Despite widespread population declines of North American grassland birds, effects of anthropogenic disturbance on wintering habitat of this guild remain poorly understood. We compared avian abundance and habitat structure in fields planted to the exotic grass Old World bluestem ( Bothriochloa ischaemum ; OWB) to that in native mixed-grass prairie. During winters of 2007–2008 and 2008–2009, we conducted bird and vegetation surveys in six native grass and six OWB fields in Garfield, Grant, and Alfalfa counties, Oklahoma. We recorded 24 species of wintering birds in native fields and 14 species in OWB monocultures. While vegetation structure was similar between field types, abundance of short-eared owls ( Asio flammeus ), northern harriers ( Circus cyaneus ) and Smith’s longspurs ( Calcarius pictus ) was higher in OWB fields during at least one year. The use of OWB fields by multiple species occupying different trophic positions suggested that vegetation structure of OWB can meet habitat requirements of some wintering birds, but there is insufficient evidence to determine if it provides superior conditions to native grasses.

Five new records of ants (Hymenoptera: Formicidae) for Nebraska
Ants are ubiquitous and influential organisms in terrestrial ecosystems. About 1,000 ant species occur in North America, where they are found in nearly every habitat (Fisher and Cover 2007). Ants are critical to ecological processes and structure. Ants affect soils via tunneling activity (Baxter and Hole 1967), disperse plant seeds (Lengyel et al. 2009), prey upon a variety of insects and other invertebrates (Way and Khoo 1992, Folgarait 1998), are often effective primary consumers through their prodigious consumption of floral and especially extrafloral nectar, and honeydew (Tobin 1994), and serve as prey for invertebrates (Gotelli 1996, Gastreich 1999) and vertebrates (Reiss 2001).

Associations between iron concentration and productivity in montane streams of the Black Hills, South Dakota
Iron is an important micronutrient found in aquatic systems that can influence nutrient availability (e.g., phosphorus) and primary productivity. In streams, high iron concentrations often are associated with low pH as a result of acid mine drainage, which is known to affect fish and invertebrate communities. Streams in the Black Hills of South Dakota are generally circumneutral in pH, yet select streams exhibit high iron concentrations associated with natural iron deposits. In this study, we examined relationships among iron concentration, priphyton biomass, macroinvertebrate abundance, and fish assemblages in four Black Hills streams. The stream with the highest iron concentration (~5 mg Fe/L) had reduced periphyton biomass, invertebrate abundance, and fish biomass compared to the three streams with lower iron levels (0.1 to 0.6 mg Fe/L). Reduced stream productivity was attributed to indirect effects of ferric iron Fe +++ ), owing to iron-hydroxide precipitation that influenced habitat quality (i.e., substrate and turbidity) and food availability (periphyton and invertebrates) for higher trophic levels (e.g., fish). Additionally, reduced primary and secondary production was associated with reduced standing stocks of salmonid fishes. Our findings suggested that naturally occurring iron deposits may constrain macroinvertebrate and fish production.

Salamander colonization of Chase Lake, Stutsman County, North Dakota
Salt concentrations in lakes are dynamic. In the western United States, water diversions have caused significant declines in lake levels resulting in increased salinity, placing many aquatic species at risk (Galat and Robinson 1983, Beutel et al. 2001). Severe droughts can have similar effects on salt concentrations and aquatic communities (Swanson et al. 2003). Conversely, large inputs of water can dilute salt concentrations and contribute to community shifts (Euliss et al. 2004).

Distribution of burrowing owls in east-central South Dakota
Western burrowing owl (Athene cunicularia hypugaea) populations have declined across much of western North America, particularly at the northern and eastern edges of the species’ breeding range (Martell et al. 2001, Murphy et al. 2001, Shyry et al. 2001, Skeel et al. 2001, Klute et al. 2003). In South Dakota, the burrowing owl is a summer resident that historically was relatively common throughout the state, but its range has decreased in recent decades, especially in the eastern half of the state (Whitney et al. 1978, South Dakota Ornithologists’ Union [SDOU] 1991, Peterson 1995). Tallman et al. (2002) described the species as uncommon to locally common in western South Dakota, uncommon in the north-central part of the state, and casual (i.e., not within the species’ normal range, but with 3–10 records in the past 10 years) elsewhere in the eastern half. The burrowing owl is a Species of Greatest Conservation Need (South Dakota Department of Game, Fish and Parks [SDGFP] 2006) and a Level I Priority Species in South Dakota (Bakker 2005).

Summer bird use of Kansas windbreaks
Twenty-four windbreaks in Stafford and Pawnee counties in Kansas were censused for birds during the nesting seasons of 1988-1990. Eighty-nine species of birds were found in the windbreaks with 60 species believed to be nesting. Fifteen species used the windbreaks for feeding or as singing perches but did not nest, and 14 species were spring migrants. Species representing 20 taxonomic families and 15 foraging guilds nested in the windbreaks. Fifteen species were members of the omnivore/ground forager guild. Five species considered forest interior or area sensitive were found nesting in the windbreaks. Windbreak area was important in determining which species were present. Windbreaks provide habitat for a large component of the Great Plains' avifauna, including some species whose populations are decreasing in the region.
