Northern Yellowstone Mule Deer Movements and Demographics Northern Yellowstone Mule Deer Movements and Demographics
This data product includes two datasets acquired for the study of northern Yellowstone mule deer seasonal movement and survival patterns. One data set "Point Locations of Radio-collared female northern Yellowstone mule deer" provides details about the date and time of relocations of radio-collared female northern Yellowstone mule deer along with location coordinates. Habitat types with...

Bird community response to field-level integration of prairie strips Bird community response to field-level integration of prairie strips
Grassland birds are under threat worldwide due to loss of habitat to agriculture. Prairie strips are a new agricultural conservation practice composed of linear strips of reconstructed diverse, native, herbaceous, perennial vegetation designed to promote land sharing among agriculture and biodiversity, while also addressing soil and water conservation goals. We evaluated bird community...

Evaluating habitat use and relative abundance of Iowa's river otter with harvest data Evaluating habitat use and relative abundance of Iowa's river otter with harvest data
The North American river otter (Lontra canadensis) was extirpated from much of the United States in the early 20th century due to habitat loss, pollution of waterways, and overharvesting. The Iowa Department of Natural Resources began a river otter reintroduction effort in 1985, which placed otters in 14 sites across the state. Otters have since been known to occur in every county in...

Despite thousands of years of land stewardship by Indigenous Peoples, Western ideology and science predominantly influences wildlife management in North America today. Indigenous science and Traditional Ecological Knowledge (TEK) extend beyond the scope of Western science and ecological understanding to include knowledge derived from generations of people living as part of ecosystems...

The relative contributions of habitat area, configuration, and vegetative diversity on snake and lizard presence in agricultural landscapes The relative contributions of habitat area, configuration, and vegetative diversity on snake and lizard presence in agricultural landscapes
Nearly one in five reptile species is at risk of extinction. Changes in habitat area, its configuration, and vegetation diversity could affect habitat use, but their relative importance is understudied. We assessed how these factors affected reptile presence in agricultural landscapes figure in Iowa, United States, using 695 cover boards visited 16,441 times in 2015–2020. Species-wise...

Habitat amount and edge effects, not perch proximity, nest exposure, or vegetation diversity affect cowbird parasitism in agricultural landscapes Habitat amount and edge effects, not perch proximity, nest exposure, or vegetation diversity affect cowbird parasitism in agricultural landscapes
Context Prior research documented relationships between brown-headed cowbird (Molothrus ater) brood parasitism and edge effects, proximity of perches, and nest exposure. Those relationships have not been evaluated in agroecosystems containing extremes of fragmentation and vegetation diversity.Objectives We compared three existing hypotheses on how cowbirds locate host nests with two new...

Comparing the efficacy of two immobilization drug combinations for the chemical restraint of bobcats (Lynx rufus) Comparing the efficacy of two immobilization drug combinations for the chemical restraint of bobcats (Lynx rufus)
Chemical immobilization agents that provide rapid induction time, short duration of action, wide margin of safety, and postreversal recovery are important attributes to the handling process of immobilized animals. We evaluated differences in induction, recovery, and physiologic parameters in 23 (13 female, nine adults and four yearlings; 10 male, nine adults and one yearling) free...
