Response of anurans to wetland restoration on a midwestern agriculture landscape Response of anurans to wetland restoration on a midwestern agriculture landscape
Since the early 1990s, >5,000 ha of historic wetlands (and adjacent prairie) have been restored on the row-crop agricultural landscape of Winnebago County, Iowa, USA. From 2008–2011, we surveyed 22 of these sites for probabilities of occupancy and colonization by Boreal Chorus Frogs (BCF; Pseudacris maculata), Northern Leopard Frogs (NLF; Lithobates pipiens), and American Toads (AT...

Home range use and survival of southern flying squirrels in fragmented forest landscapes Home range use and survival of southern flying squirrels in fragmented forest landscapes
We studied home range use, spatial activity patterns, and annual survival of southern flying squirrels (SFS; Glaucomys volans) across fragmented landscapes of west-central Illinois. We calculated seasonal home range sizes and annual survival from 67 animals (36 males, 31 females) captured during 2014–2016. Home range and core area sizes were similar (P ≥ 0.46) among males and females...

Book review: Serendipity: An ecologist’s quest to understand nature Book review: Serendipity: An ecologist’s quest to understand nature
A common thought among graduate students is: “how do established scientists get where they are today?” In Serendipity: An Ecologist’s Quest to Understand Nature, James Estes offers a personal reflection on research experiences spanning his 50-year career, beginning as a Ph.D. student in 1970 and concluding with recognition as a member of the National Academy of Sciences in 2014.

Influence of trap modifications and environmental predictors on capture success of southern flying squirrels Influence of trap modifications and environmental predictors on capture success of southern flying squirrels
Sherman traps are the most commonly used live traps in studies of small mammals and have been successfully used in the capture of arboreal species such as the southern flying squirrel (Glaucomys volans). However, southern flying squirrels spend proportionately less time foraging on the ground, which necessitates above-ground trapping methods and modifications of capture protocols...

Associations among habitat characteristics and meningeal worm prevalence in eastern South Dakota, USA Associations among habitat characteristics and meningeal worm prevalence in eastern South Dakota, USA
Few studies have evaluated how wetland and forest characteristics influence the prevalence of meningeal worm (Parelaphostrongylus tenuis) infection of deer throughout the grassland biome of central North America. We used previously collected, county-level prevalence data to evaluate associations between habitat characteristics and probability of meningeal worm infection in white-tailed...

Long-term changes in Canade Goose nest success and nest densities at an Iowa wetland complex Long-term changes in Canade Goose nest success and nest densities at an Iowa wetland complex
Giant Canada geese (Branta canadensis maxima) were extirpated from Iowa by the early 1900s due to unregulated hunting, egg gathering, and wetland drainage in the nineteenth century (Bishop 1978). Ef- forts to reintroduce Canada geese in Iowa began in 1964 (Bishop and Howing 1972) and involved releasing flightless adults and goslings at nearly 30 sites across the state (Zenner and...
