Two subspecies of Black Rail (Laterallus jamaicensis) occur in the United States, and neither has been studied extensively. Of the two, the Eastern subspecies (L.j. jamaicensis) has a larger range, but has been studied to a lesser degree than the...
The development of informed management practices and insightful research
depends not only on an understanding of species natural history and ecology, but
information regarding the distributions of these species and how they interact with
adjacent...
"The phenotype of two Andropogon gerardii subspecies, big bluestem and sand bluestem, varies broadly throughout the Great Plains of North America, giving rise to ecotypes within the species. This study sought to discriminate between genetic and...
I assessed the utility of cranial measurements to discriminate between the western harvest mouse (Reithrodonlomys megalolis) and plains harvest mouse (R. montanus) where they occur sympatrically in Kansas. I analyzed five different combinations of...
An investigation was made to determine the role of pelage color of Peromyscus maniculatus nebrascensis in relation to the type of soil and the vegetation the Nebraska deermouse inhabits. P.M. nebrascensis displays several different shades of pelage...
I analyzed variation in a portion of the mitochondrial DNA (mtDNA) control region to determine if montane populations of the red squirrel (tamiasciurus hudsonicus) in Colorado are isolated andto relate genetic variation in the species to glacial...
Does the subspecies concept reflect meaningful subdivisions within small mammal species on the Central Great Plains? The 11 species of mammals included in this study exhibit an east-west pattern of variation in pelage color and size. Because of...
The taxonomic relationship of two supposed species of Geomys in northern Kansas was assessed using morphometric, bacular, karyotypic, and electrophoretic analyses. Only morphometric analysis proved useful in differentiating between the taxa. No...
Geographic variation among populations of Onychomys leucogaster in western North America was investigated using morphometric, karyotypic , and fossil data. Populations previously considered to represent O. l. utahensis, as well as those from the...
Systematic relationships of populations of the northern grasshopper mouse, Onychomys leucogaster, on the central Great Plains are assessed based on study of molts and pelages and on morphometric analyses. Variation in color of any one population...
Systematic relationships among six chromosomal races of Geomys bursarius on the Central Great Plains were assessed using morphometric and electrophoretic methods. Gross cranial morphology was inadequate as a discriminator among most races and...
The taxonomic status of the Arizona myotis (Myotis occultus) is uncertain. Although the taxon was described as a distinct species and currently regarded as such by some authors, others have noted what they interpreted as intergradation with the...
Two coyote species, Canis lepophagus and the modern coyote, Canis latrans are known from the Pliocene and Pleistocene of North America. Canis lepophagus generally is considered a Blancan species, and the oldest specimens that can confidently be...
The southern short-tailed shrew (Blarina carolinensis) inhabits the Mississippi
Alluvial Plain, the Gulf Coastal Plain, Florida, and the Atlantic Coastal Plain as far north
as Virginia. Since its description by Bachman in 1837, this species has...
