To understand ongoing declines and plan for conservation, researchers need reliable estimates of adult survival and site fidelity. However, variation in adult survival and site fidelity within and among species is substantial and could have consequences for management. Estimates of adult survival are lacking for many bird species and ecoregions, including the Great Plains. In this field study, we used Cormack-Jolly-Seber mark-recapture models to analyze encounter histories of 17 species of birds captured with a 13-year systematic mist-netting effort in northeast Kansas. We estimated annual rates of apparent adult survival (/) and corrected for the probability of capture (p), and tested for effects of sex and breeding habitat guild. We present the first estimates of apparent survival for six species of songbirds, and the first estimates from the Great Plains for 13 species. Apparent survival tended to be higher for males than for females, and we found a sex effect on the probability of capture for one species. Unexpectedly, grassland- and shrubland-breeding species had higher estimates of apparent survival than forest-breeding species. Our results did not support the prevailing viewpoint that birds breeding in dynamic landscapes, such as frequently burned grasslands, should show lower apparent survival than species that breed in woody habitats. We demonstrate that habitat plays an important role in the survival and site fidelity of songbirds, and that regional differences in habitat structure could drive variation in demography. Understanding the drivers of true survival and site fidelity of songbirds will allow region-specific management for species of conservation concern.</p>10aCormack-Jolly-Seber models10ahabitat guilds10asite fidelity10asongbird10atallgrass prairie10awoodpe1 aVerheijen, B.H.F.1 aRintoul, D.A.1 aSandercock, B.K.  uhttps://doi.org/10.1676/16-017.101906nas a2200217   4500008004100000245015500041210006900196300001300265490000700278520109200285653003701377653002701414653001701441653002401458653001401482100001801496700001801514700001601532700001701548856012301565       2005                        eng d00aCarrion beetles (Coleoptera: Silphidae) of the Konza Prairie Biological Stationbeetles (Coleoptera: Silphidae) of the Konza Prairie Biological Station0 aCarrion beetles Coleoptera Silphidae of the Konza Prairie Biolog  a124 -1230 v783 aPitfall traps were used to determine diversity, seasonality, and numbers of burying beetles on the Konza Prairie Biological Station (KPBS) during the summers of 1997 and 1998. Traps were baited with either beef liver (1997) or whole mouse carcasses (1997 and 1998); significantly more carrion beetles were found in traps baited with carcasses. A total of 1003 carrion beetles, representing 8 species, were trapped over the course of 1556 trap nights. One of these species, Necrophila americana Linneaus, had not previously been recorded in Riley County. One additional species was found at sites where pitfall trap bait was discarded, bringing the total number of KPBS silphid species to 9. Bait age was an important determinant in attracting silphids to pitfall traps, as numbers of beetles in the trap continued to increase with bait age up to 6 days. Grassland topography (upland vs. lowland trap sites) significantly affected the numbers of carrion beetles trapped. Grassland burn history did not affect number of carrion beetles trapped, but did seem to influence species diversity.10aKonza Prairie Biological Station10aNicrophorus marginatus10apitfall trap10aseasonal occurrence10aSilphidae1 aRintoul, D.A.1 aKrueger, L.M.1 aWoodard, C.1 aThrone, J.E.  uhttp://knz.lternet.edu/content/carrion-beetles-coleoptera-silphidae-konza-prairie-biological-stationbeetles-coleoptera02161nas a2200217   4500008004100000245006400041210006400105300001100169490000700180520151900187653000901706653002201715653001801737653001101755653002201766100001501788700001801803700001801821700001801839856008601857       2004                        eng d00aInfluence of prey abundance on raptors in tallgrass prairie0 aInfluence of prey abundance on raptors in tallgrass prairie  a23 -320 v363 a<p>We examined relationships between winter abundance of diurnal raptors (red-tailed hawk, Buteo jamaicensis; rough-legged hawk, B. lagopus; ferruginous hawk, B. regalis; and northern harrier, Circus cyaneus) and both the abundance of microtine rodents (prairie vole, Microtus ochrogaster; and southern bog lemming, Synaptomys cooperi) and aboveground net primary productivity (ANPP) in tallgrass prairie. We used Christmas Bird Count data for each year during 1975 through 1999 from Manhattan, Kansas to index winter raptor abundance (number of hawks per party hour). Microtine rodent abundance (average number of microtine rodents per trapline in burned and unburned prairie) was estimated by using long-term data gathered from autumn and spring surveys along 14 permanent traplines from autumn 1981 to spring 2000 in tallgrass prairie on the Konza Prairie Biological Station. An estimate of ANPP for each year during 1975 through 1999 was provided by the Konza Prairie Long-Term Ecological Research Program. Winter raptor abundance was related positively to ANPP during the preceding growing season (P = 0.01) and to microtine abundance in the previous spring (P = 0.03). Based on a stepwise regression, 39% of the annual variation in winter raptor counts was explained by ANPP and the log of spring microtine abundance. Overall, our analyses suggested that winter raptor abundance was higher in years with higher than lower prey availability, but that other factors also influenced winter raptor abundance.</p>10aANPP10amicrotine rodents10apredator-prey10araptor10atallgrass prairie1 aReed, A.W.1 aKaufman, G.A.1 aRintoul, D.A.1 aKaufman, D.W.  uhttp://knz.lternet.edu/content/influence-prey-abundance-raptors-tallgrass-prairie00529nas a2200133   4500008004100000245008300041210006900124300001100193490000700204100001700211700001700228700001800245856013200263       1998                        eng d00aHybridization of Mountain Bluebird and Eastern Bluebird in Northeastern Kansas0 aHybridization of Mountain Bluebird and Eastern Bluebird in North  a21 -320 v491 aCavitt, J.F.1 aPearse, A.T.1 aRintoul, D.A.  uhttps://www.researchgate.net/publication/268287117_Hybridization_o_Mountain_Bluebird_and_Eastern_Blubird_In_Northeastern_Kansas
