How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Increased urbanization and supplementary feeding are implicated in driving the expansion of the range of the Anna’s Hummingbird (Calypte anna). In many areas this range expansion has been well described, but the recent expansion of the northeastern limit of the nonbreeding distribution, in winter in Idaho, has not yet been summarized. Using data fr...
Several past studies have demonstrated the effects of anthropogenic noise on populations of animals. Yet, differing effects of noise by age and subsequent changes in the age structure of populations are poorly understood. We experimentally tested the effects of traffic noise alone on the age structure of a community of migrating birds at a fall sto...
Significance Using landscape-scale traffic noise playbacks to create a “phantom road,” we find that noise, apart from other factors present near roads, degrades the value of habitat for migrating songbirds. We found that nearly one third of the bird community avoided the phantom road. For some bird species that remained despite noise exposure, body...
Many authors have suggested that the negative effects of roads on animals are largely owing to traffic noise. Although suggestive, most past studies of the effects of road noise on wildlife were conducted in the presence of the other confounding effects of roads, such as visual disturbance, collisions and chemical pollution among others. We present...
I'm working on a project to create a library of pollen with known species (collected from flowers) to compare with unknown pollen (collected from hummingbirds).
In reading through the literature, it sounds like acetolysis is the preferred method for keeping slides of pollen long term. And that there is some risk of mildew if the pollen is not acetolyzed. This this true?
If possible, I'd like to use the fuchsine stain + jelly method to make our "known" slides, since our "unknown" samples from hummingbirds will be collected using that method. Does fuchsine/jelly for mounting on a slide (with cover slip and fingernail polish) work for long term slide libraries without risking mildew?
We monitor trends in curlew populations, track nest success in varied landscapes, use satellite transmitters to follow migratory routes and assess spatial movements on the wintering grounds, and measure vegetation and landcover variables associated with Long-billed Curlews breeding in the Intermountain West. Diverse partnerships and collaborations help us to share our research with a broad audience through school programs, media stories, peer-reviewed journals, and public events. Ultimately, our goals are to enhance conservation efforts of curlews through collaborative partnerships, sound science, and interactive outreach and education programs.
Since 2015 we have monitored songbird populations through standardized banding protocols during the breeding season and fall migration season at our Boise River Research Station, located in the greater Barber Pool Ecosystem. Our goal is to monitor populations of riparian obligate breeding birds and long-distance neotropical migrants, as these groups are facing numerous conservation threats.
In Idaho, Anna's Hummingbird numbers have increased in the fall and winter, particularly over the past decade. We have developed a winter banding program to monitor this population expansion
