Temporal Variations Of Extreme Precipitation Events In The United States: 1895–2000, Kenneth E. Kunkel, David R. Easterling, Kelly Redmond, Kenneth Hubbard
Temporal Variations Of Extreme Precipitation Events In The United States: 1895–2000, Kenneth E. Kunkel, David R. Easterling, Kelly Redmond, Kenneth Hubbard
Papers in Natural Resources
A newly available data set of daily precipitation observations was used to study the temporal variability of the frequency of short-duration extreme precipitation events for 1895–2000 in the conterminous United States. Event durations of 1, 5, 10, and 30 day and return periods of 1, 5, and 20 year were analyzed. For all combinations of duration and return period, heavy precipitation frequencies were relatively high during the late 19th/early 20th Centuries, decreasing to a minimum in the 1920s and 30s, followed by a general increase into the 1990s. The frequencies at the beginning of the 20th Century were nearly as …

Survival Rates And Recovery Distributions Of Canada Geese Banded In Nebraska, Larkin A. Powell, Mark Vrtiska, Nick Lyman
Survival Rates And Recovery Distributions Of Canada Geese Banded In Nebraska, Larkin A. Powell, Mark Vrtiska, Nick Lyman

We analyzed banding and recovery data for Canada geese (Branta canadensis) banded in Nebraska during 1990–2000. Survival rates were lower during 1996–2000 (adult: 0.688, SE = 0.016; juvenile: 0.611, SE = 0.029), than 1990–1995 (adult: 0.727, SE = 0.011; juvenile: 0.639, SE = 0.024). Average juvenile-to-adult ratio from banding data was 0.834 (SD = 0.485), resulting in an annual population growth rate (λ) estimate for 1990–1995 of 0.995 (95% CI = 0.021), and 0.922 (0.018) for 1996–2000. Our recovery analysis suggests that 67% of geese banded in Nebraska are shot in Nebraska. Over 30% of both juvenile and adult recoveries …

Urban Canada Geese In Georgia: Assessing A Golf Course Survey And A Nuisance Relocation Program, Larkin A. Powell, Michael J. Conroy, Kipling S. Balkcom, Joe Caudell

Nuisance complaints about Canada geese (Branta canadensis), have risen in recent years. In Georgia, managers have responded by relocating some nuisance geese to rural areas. During 1993–1996, we used band recoveries of relocated geese to determine the efficacy of relocation as a management strategy. We also used data from a post-card survey of golf courses to monitor the urban subpopulation of Canada geese in Georgia during 1998–2001. Flocks considered by golf course superintendents to be a nuisance were larger (1998: 48.8 geese, 1999: 71.5, 2000: 73.2, 2001: 67.2) than nonnuisance flocks (1998: 13.1 geese, 1999: 16.7, 2000: 25.8, 2001: 18.1). …
Wattle Size Is Correlated With Male Territorial Rank In Juvenile Ring-Necked Pheasants, Anna Papeschi, John P. Carroll, Francesco Dessi-Fulgheri
Wattle Size Is Correlated With Male Territorial Rank In Juvenile Ring-Necked Pheasants, Anna Papeschi, John P. Carroll, Francesco Dessi-Fulgheri

We used morphological measurements and behavioral observations to investigate the relationship between male ornaments and male social rank during the breeding season in a free-ranging population of one-year-old Ring-necked Pheasants (Phasianus colchicus). The sample was of birds of the same age class to avoid the confounding effect of age differences. Tail length, used by females in mate choice, and tarsal spur length, used by males as a weapon in fights, were not correlated with male rank, whereas the size of the wattle was the most important trait. This combined with recent studies showing that wattle size reliably indicates …
The Ceres-Rice Model-Based Estimates Of Potential Monsoon Season Rainfed Rice Productivity In Bangladesh, Rezaul Mahmood, Mark Meo, David R. Legates, Mark L. Morrissey
The Ceres-Rice Model-Based Estimates Of Potential Monsoon Season Rainfed Rice Productivity In Bangladesh, Rezaul Mahmood, Mark Meo, David R. Legates, Mark L. Morrissey

Agricultural practices in Bangladesh are largely dependent on the monsoonal rainfall. Historically, Bangladesh often experiences severe droughts and floods during the monsoon months, with significant crop losses during both extreme conditions. This article provides a quantitative assessment of potential monsoon-season aman rice for four transplanting dates: 1 June, 1 July, 15 July, and 15 August. A crop-growth simulation model, the CERES-Rice, is applied to sixteen locations representing major rice-growing regions of Bangladesh to determine baseline yield estimates for four transplanting dates. The applications were conducted for 1975 through 1987. Average potential yield in Bangladesh is 6,907, 5,039, 3,637, and 1,762 …
