Biodiversity losses: The downward spiral
Diana F. Tomback, Katherine C. Kendall
Diana F. Tomback, Stephen F. Arno, Robert E. Keane, editor(s)
2001, Book chapter, Whitebark pine communities: Ecology and restoration
The dramatic decline of whitebark pine (Pinus albicaulis) populations in the northwestern United States and southwestern Canada from the combined effects of fire exclusion, mountain pine beetles (Dendroctonus ponderosae), and white pine blister rust (Cronartium ribicola), and the projected decline of whitebark pine populations rangewide (Chapters 10 and 11) do...
Uncertainty and spatial linear models for ecological data
Jay M Ver Hoef, Noel Cressie, Robert N. Fisher, Ted J. Case
C. Hunsaker, M. Goodchild, Mark A. Friedl, Ted J. Case, editor(s)
2001, Book chapter, Spatial uncertainty in ecology
Models are not perfect; they do not fit the data exactly and they do not allow exact prediction. Given that models are imperfect, we need to assess the uncertainties in the fits of the models and their ability to predict new outcomes. The goals of building models for scientific problems...
Radiocarbon studies of plant leaves and rings from mammoth mountain, CA: A long-term record of magmatic CO2 release
A.C. Cook, L.J. Hainsworth, M.L. Sorey, William C. Evans, J. R. Southon
2001, Chemical Geology (177) 117-131
Evaluation of 14C in tree rings provides a measure of the flux of magmatic CO2 from Mammoth Mountain both before and after 1994 when copious diffuse emissions were first discovered and linked to tree kill. We analyzed the annual rings of trees with two main purposes: (1) to track changes...
Prevalence of giant kidney worm (Dioctophyma renale) in wild mink (Mustela vison) in Minnesota
L. David Mech, Shawn P. Tracy
2001, American Midland Naturalist (145) 206-209
Of 138 wild mink (Mustela vison) from eastern Minnesota, 27% contained Dioctophyma renale, primarily in the right kidney. No significant difference between prevalence in adult male and immature male mink was found, nor between the prevalence in males versus female mink. Thirteen worms were found in one male mink, representing...

Relationship of bull fertility to sperm nuclear shape
G.C. Ostermeier, G.A. Sargeant, B.S. Yandell, J.J. Parrish
2001, Journal of Andrology (22) 595-603
The relationship between sperm nuclear shape and bull fertility was determined. Two groups of bulls, 3 per group, were selected. Bulls differed in fertility based on lifetime nonreturn rates. Digital images of propidium iodide-stained sperm from each bull were collected and shape-evaluated by Fourier harmonic amplitudes 0 to 5. A...
Recent observations of the distribution and status of bluntnose darters and crystal darters in Iowa
M.C. Bowler
2001, Journal of the Iowa Academy of Science (108) 15-18
The distribution and status of Iowa's fishes were last extensively described in Iowa Fish and Fishing (Harlan et al. 1987). Since then, numerous fish collections have been made in Iowa's interior and bordering rivers and streams. Excluding non-native species, there have been three documented accounts of new fish species distributional...
