Pelvic Sexual Dimorphism In A Metatherian, Didelphis Virginiana: Implications For Eutherians, Robert G. Tague Nov 2003

Pelvic Sexual Dimorphism In A Metatherian, Didelphis Virginiana: Implications For Eutherians, Robert G. Tague

Faculty Publications

Eutherians give birth to relatively large infants. Females have larger pelves than males, though males typically have larger nonpelvic bones. Pelvic dimorphism is an adaptation for parturition. Metatherian females, who give birth to markedly small infants, should not show pelvic adaptations for parturition and should have smaller pelves than males. Adult females and males of the Virginia opossum, Didelphis virginiana, are compared. Males are significantly larger than females in absolute size for 14 of 16 pelvic and 8 nonpelvic measures. Sexes did not differ significantly for lower iliac length and posterior space of midplane. However, relative lengths for females are …


Synergistic Use Of Lidar And Color Aerial Photography For Mapping Urban Parcel Imperviousness, Michael E. Hodgson, John R. Jensen, Jason A. Tullis, Kevin D. Riordan, Clark M. Archer Sep 2003

Synergistic Use Of Lidar And Color Aerial Photography For Mapping Urban Parcel Imperviousness, Michael E. Hodgson, John R. Jensen, Jason A. Tullis, Kevin D. Riordan, Clark M. Archer

Faculty Publications

The imperviousness of land parcels was mapped and evaluated using high spatial resolution digitized color orthophotography and surface-cover height extracted from multiple-return lidar data. Maximum-likelihood classification, spectral clustering, and expert system approaches were used to extract the impervious information from the datasets. Classified pixels (or segments) were aggregated to parcels. The classification model based on the use of both the orthophotography and lidar-derived surface-cover height yielded impervious surface results for all parcels that were within 15 percent of reference data. The standard error for the rule-based per-pixel model was 7.15 percent with a maximum observed error of 18.94 percent. The …

Interrelationships Among Landscapes, Ndvi, And Stream Water Quality In The Us Central Plains, Jerry A. Griffith, Edward A. Martinko, Jerry L. Whistler, Kevin P. Price Dec 2002

Interrelationships Among Landscapes, Ndvi, And Stream Water Quality In The Us Central Plains, Jerry A. Griffith, Edward A. Martinko, Jerry L. Whistler, Kevin P. Price

Faculty Publications

During late spring through summer of 1994 and 1995, 290 randomly selected stream sites in Nebraska, Kansas, and Missouri were sampled once for several parameters including conductivity, turbidity, total phosphorus, nitrate-nitrite nitrogen, the index of biotic integrity, and a habitat index. Based on landscape data from watersheds that were delineated for each sampling location, interrelationships were examined between these water quality parameters and land use/land cover, the normalized difference vegetation index (NDVI), and vegetation phenological metrics derived from the NDVI. Statistically significant relationships were found between NDVI values and the derived metrics with the stream condition parameters (r values to …

Dam Nation: A Geographic Census Of American Dams And Their Large-Scale Hydrologic Impacts, William L. Graf Jan 1999

Dam Nation: A Geographic Census Of American Dams And Their Large-Scale Hydrologic Impacts, William L. Graf

Faculty Publications

Newly available data indicate that darns fragment the fluvial system of the continental United States and that their impact on river discharge is several times greater than impacts deemed likely as a result of global climate change. The 75,000 dams in the continental United States are capable of storing a volume of water almost equaling one year's mean runoff, but there is considerable geographic variation in potential surface water impacts. In some western mountain and plains regions, darns can store more than 3 year's runoff, while in the Northeast and Northwest, storage is as little as 25% of the annual …

Variability Of A Vestigial Structure: First Metacarpal In Colobus Guereza And Ateles Geoffroyi, Robert G. Tague Jan 1997

Variability Of A Vestigial Structure: First Metacarpal In Colobus Guereza And Ateles Geoffroyi, Robert G. Tague

Faculty Publications

A tenet of evolutionary theory is that, under conditions of stabilizing selection, phenotypic variability is inversely related to selection intensity. Correspondingly, a nonfunctional, vestigial structure is expected to be highly variable relative to its functional homologue. This study tests the hypothesis that species with a vestigial pollex, Colobus guereza and Ateles geoffroyi, have a first metacarpal whose length is both highly variable relative to, and poorly correlated with, the lengths of the other metapodials. The results are consistent with the hypothesis, though this combination of traits is also found in Presbytis rubicunda and Presbytis cristata. The latter two species have …

Data Assimilation And Model Evaluation Experiment Datasets, Chung-Chieng A. Lai, Wen Qian, Scott M. Glenn

Faculty Publications

The Institute for Naval Oceanography, in cooperation with Naval Research Laboratories and universities, executed the Data Assimilation and Model Evaluation Expertiment (DAMÉE) for the Gulf Stream region during fiscal years 1991-1993. Enormous effort has gone into the preparation of several high-quality and consistent datasets for model initialization and verification. This paper describes the preparation process, the temporal and spatial scopes, the contents, the structure, etc., of these datasets.

The goal of DAMÉE and the need of data for the four phases of experiment are briefly states. The preparation of DAMÉE datasets consisited of a series of processes: 1) collection of …
