Canada goose nest survival at rural wetlands in north-central Iowa Canada goose nest survival at rural wetlands in north-central Iowa
The last comprehensive nest survival study of the breeding giant Canada goose (Branta canadensis maxima) population in Iowa, USA, was conducted >30 years ago during a period of population recovery, during which available nesting habitat consisted primarily of artificial nest structures. Currently, Iowa's resident goose population is stable and nests in a variety of habitats. We analyzed...

Book review: Large carnivore conservation: Integrating science and policy in the North American West Book review: Large carnivore conservation: Integrating science and policy in the North American West
Dr. Klaver reviewed Large Carnivore Conservation as part of a graduate seminar and seminar participants represented the full range of readers who might be interested in the book: natural resource managers, citizen advocates, researchers, and students. Although we encountered a variety of opinions based on our different backgrounds and orientations, we discovered a surprising amount of...

Age-specific survival of reintroduced swift fox in Badlands National Park and surrounding lands Age-specific survival of reintroduced swift fox in Badlands National Park and surrounding lands
In 2003, a reintroduction program was initiated at Badlands National Park (BNP), South Dakota, USA, with swift foxes (Vulpes velox) translocated from Colorado and Wyoming, USA, as part of a restoration effort to recover declining swift fox populations throughout its historical range. Estimates of age-specific survival are necessary to evaluate the potential for population growth of...

Do transmitters affect survival and body condition of American beavers Castor canadensis? Do transmitters affect survival and body condition of American beavers Castor canadensis?
One key assumption often inferred with using radio-equipped individuals is that the transmitter has no effect on the metric of interest. To evaluate this assumption, we used a known fate model to assess the effect of transmitter type (i.e. tail-mounted or peritoneal implant) on short-term (one year) survival and a joint live—dead recovery model and results from a mark—recapture study to...

Restored agricultural wetlands in Central Iowa: habitat quality and amphibian response Restored agricultural wetlands in Central Iowa: habitat quality and amphibian response
Amphibians are declining throughout the United States and worldwide due, partly, to habitat loss. Conservation practices on the landscape restore wetlands to denitrify tile drainage effluent and restore ecosystem services. Understanding how water quality, hydroperiod, predation, and disease affect amphibians in restored wetlands is central to maintaining healthy amphibian populations in...

Effects of climate and plant phenology on recruitment of moose at the southern extent of their range Effects of climate and plant phenology on recruitment of moose at the southern extent of their range
Climate plays a fundamental role in limiting the range of a species, is a key factor in the dynamics of large herbivores, and is thought to be involved in declines of moose populations in recent decades. We examined effects of climate and growing-season phenology on recruitment (8–9 months old) of young Shiras moose (Alces alces shirasi) over three decades, from 18 herds, across a large...
