Avian Influenza Virus Prevalence In Migratory Waterfowl In The United States, 2007-2009, Scott R. Groepper Mr., Thomas Deliberto, Mark Vrtiska, Kerri Pedersen, Seth Swafford, Scott Hyngstrom

SUMMARY. We analyzed 155,535 samples collected for surveillance of avian influenza viruses (AIVs), in the United States from 2007 to 2009, from migratory waterfowl (ducks, geese, and swans). The goal was to elucidate patterns of prevalence by flyway and functional groups to determine targets for future surveillance. Apparent prevalence of AIV was highest in the Pacific Flyway in 2007–2008 (14.2% and 14.1%, respectively), in the Mississippi Flyway in 2009 (16.8%), and lowest each year in the Atlantic Flyway (range, 7.3%–8.9%). Dabbling ducks had higher apparent prevalence of AIV (12.8%–18.8%) than diving ducks (3.9%–6.0%) or geese and swans (3.6%–3.9%). We observed …

Real And Perceived Damage By Wild Turkeys: A Literature Review, Scott R. Groepper, Scott E. Hygnstrom Dr, Brandon Houck, Stephen M. Vantassel

As populations of wild turkeys (Meleagris gallopavo) have increased, the number of complaints about damage has increased. We conducted a literature review to determine real and perceived damage caused by wild turkeys in North America. Wild turkeys can cause damage to agricultural crops, such as corn (Zea mays L.), soybeans (Glycine max [L.] Merrill), wheat, and hay crops but the majority of actual damage is usually minor or caused by other wildlife, thus estimates of damage by wild turkeys often are inflated. Occasionally, wild turkeys damage specialty crops, turfgrass, or ornamental flowers that may have higher value than common agricultural …

ABSTRACT Populations of temperate-nesting Canada geese (Branta canadensis) have increased in Nebraska, USA, resulting in an increased number of nuisance and damage complaints. September hunting seasons were initiated in southeastern Nebraska in 2004 to reduce populations of Canada geese. We analyzed band recoveries from Canada geese banded in southeastern Nebraska during their hatch-year (HY) or after hatch-year (AHY) to determine whether September hunting seasons affected survival, harvest, and recovery rates. Survival analyses revealed that HY geese had higher survival than AHY geese (SAHY = 0.696, 95% CI = 0.679–0.713; SHY = 0.896, 95% CI = 0.786–0.953) and September seasons did …
Landowner Attitudes Toward Elk Management In The Pine Ridge Region Of North-Western Nebraska, R. Daniel Crank, Scott E. Hygnstrom, Scott R. Groepper Mr., Kit M. Hams
Landowner Attitudes Toward Elk Management In The Pine Ridge Region Of North-Western Nebraska, R. Daniel Crank, Scott E. Hygnstrom, Scott R. Groepper Mr., Kit M. Hams

Abstract: Little is known about attitudes of landowners toward elk (Cervus elaphus) on privately-owned land. We mailed questionnaires to agricultural landowners in the Pine Ridge region of northwestern Nebraska in both 1995 and 1997 to determine attitudes toward elk populations and management of elk. Fifty-six percent (n = 214) of respondents in 1995 and 57% (n = 461) in 1997 were in favor of free-ranging elk. Motivation for those in favor of elk was utilitarian (opportunity to view and hunt elk), ecological (return of a native species), and economic (benefi ts from increased tourism and leased land for elk hunting). …
