Karyotypic Relationships Within The Short-Tailed Shrews, Genus Blarina, Sarah B. George, Hugh H. Genoways, Jerry R. Choate, Robert J. Baker
Karyotypic Relationships Within The Short-Tailed Shrews, Genus Blarina, Sarah B. George, Hugh H. Genoways, Jerry R. Choate, Robert J. Baker
University of Nebraska State Museum: Mammalogy Papers
Short-tailed shrews of the genus Blarina exhibit considerable geographic variation in both diploid number and fundamental number. Four chromosomal groups are recognized within the genus: Blarina brevicauda, FN = 48; 2N = 50, 49, or 48; B. carolinensis, FN = 45 or 44; 2N = 46, 39, 38, or 37; B. c. peninsulae, FN = 52; 2N = 52, 51, or 50; B. hylophaga, FN = 62, 61, or 60; 2N = 52. B. c. peninsulae also may be a distinct species, but exact determination must await location and analysis of a zone of contact with …

An Analysis Of Howling Response Parameters Useful For Wolf Pack Censusing, Fred H. Harrington, L. David Mech
An Analysis Of Howling Response Parameters Useful For Wolf Pack Censusing, Fred H. Harrington, L. David Mech
USGS Northern Prairie Wildlife Research Center
Gray wolves (Canis lupus) were studied from April 1972 through April 1974 in National Forest in northeastern Minnesota by radio-tracking and simulated howling. Based during 217 of 456 howling sessions, the following recommendations were derived for using howling as a census technique: (1) the best times of day are dusk and night; (2) July, August, and are the best months; (3) precipitation and winds greater than 12 km/hour should be avoided; (of 5 single howls should be used, alternating "flat" and "breaking" howls; (5) trials should 3 times at about 2-minute intervals with the first trial at lower …
Distributions, Densities, And Relative Abundances Of Grasshoppers (Orthoptera: Acrididae) In A Nebraska Sandhills Prairie, Anthony Joern
Distributions, Densities, And Relative Abundances Of Grasshoppers (Orthoptera: Acrididae) In A Nebraska Sandhills Prairie, Anthony Joern
Entomology Papers from Other Sources
Grasshoppers (Orthoptera: Acrididae) represent a conspicuous and often important component of grassland systems (Odum et al. 1962, Smalley 1960, Sinclair 1975, Van Hook 1971, Wiegert 1965). Often, assemblages of grasshoppers are quite diverse and may, on occasion, consume a large fraction of the available vegetation (Hewitt 1977, Hewitt et al. 1976, Mitchell and pfadt 1974). As such, grasshoppers have the potential of being very important in the nutrient and energy flow in grassland ecosystems. However, to understand the impact of grasshoppers at the ecosystem level requires that the densities and fluctuations of populations as well as the species composition of …

Preliminary Report Of Colony Survivorship In The Western Harvetser Ant (Pogonomyrmex Occidentalis) In Western Nebraska, Kathleen H. Keeler
Preliminary Report Of Colony Survivorship In The Western Harvetser Ant (Pogonomyrmex Occidentalis) In Western Nebraska, Kathleen H. Keeler
School of Biological Sciences: Faculty Publications
Colonies of Pogonomyrmex occidentalis Cresson (Hymenoptera: Formicidae) may live an average of 22 to 43 years. The population dynamics of individual colonies of P. occidentalis adjacent to the Univ. Nebraska's Cedar Point Biol. Sta., Keith Co., Nebraska, is the subject of an ongoing investigation. The habitat is a moderately grazed shortgrass prairie dominated by Bouteloua hirsuta, B. gracilis, and Buchloe dactyloides, with Stipa comata, Aristida spp., and various forbs. The colonies studied are in a triangular area about 400 m long and 100 m across at the widest point. The area appears to be at carrying …
Morphometric And Geographic Relationships Of Short-Tailed Shrews (Genus Blarina) In Kansas, Iowa, And Missouri, Nancy D. Moncrief, Jerry R. Choate, Hugh H. Genoways
Morphometric And Geographic Relationships Of Short-Tailed Shrews (Genus Blarina) In Kansas, Iowa, And Missouri, Nancy D. Moncrief, Jerry R. Choate, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Shrews of the genus Blarina from Iowa, Kansas, and Missouri were studied morphometrically and karyologically. The ranges of two species, B. brevicauda and B. hylophaga, overlap in a broad zone across southern Iowa and northern Missouri. Morphometric analyses revealed an unexpectedly large amount of cranial variation in B. brevicauda, and confirmed the presence of that species in the Kansas River Valley of northeastern Kansas. Considerable mensural overlap was found in geographic areas in which B. hylophaga and B. brevicauda are sympatric, evincing the need for further karyotypic and morphometric studies in those areas. No formal taxonomic changes are …

Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf
Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf
Avian Cognition Papers
An ecological approach based on food distribution suggests that hummingbirds should more easily learn to visit a flower in a new location than to learn to return to a flower in a position just visited, for a food reward. Experimental results support this hypothesis as well as the general view that differences in learning within and among species represent adaptations.
Distribution Ecology: Variation In Plant Recruitment Over A Gradient In Relation To Insect Seed Predation, Svata M. Louda
Distribution Ecology: Variation In Plant Recruitment Over A Gradient In Relation To Insect Seed Predation, Svata M. Louda
Svata M. Louda Publications
Although predispersal seed predation by insects is common, no test exists of its effect on plant recruitment. This study examines seed predation in the population dynamics of a native, temperate shrub, Haplopappus squarrosus H. and A. (Asteraceae), over an elevational gradient in the coastal sage scrub vegetation of San Diego County, California, USA. Frequency and abundance of H. squarrosus increase from coast to mountains. Expected abundance, based on flowers initiated, was highest at the coast and lowest in the interior, the opposite of the observed adult plant distribution. Overall flower and seed predation by insects was high (44-73%) and was …
The Suriname Small Mammal Survey: A Case Study Of The Cooperation Between Research And National Conservation Needs, Hugh H. Genoways, Henry A. Reichart, Stephen L. Williams
The Suriname Small Mammal Survey: A Case Study Of The Cooperation Between Research And National Conservation Needs, Hugh H. Genoways, Henry A. Reichart, Stephen L. Williams
University of Nebraska State Museum: Mammalogy Papers
A cooperative program between the Foundation for Nature Preservation in Suriname and the Carnegie Museum of Natural History to survey the small mammals of Suriname is reviewed. The program has proven to be mutually beneficial and it is presented as a model for development of similar programs in the future. The technical assistance requested by the Foundation for Nature Preservation in Suriname concerned the distribution and natural history of small mammals, especially those occurring in the Nature Parks and Reserves. The Government of Suriname has established an excellent system of Reserves and Parks throughout the country. They are trying to …
Response Strategies In The Radial Arm Maze: Running Around In Circles, Sonja I. Yoerg, Alan C. Kamil
Response Strategies In The Radial Arm Maze: Running Around In Circles, Sonja I. Yoerg, Alan C. Kamil
Papers in Behavior in Biological Sciences
The effects of the size of the central arena on the use of response strategies by rats on an eight~arm elevated maze were examined. The size of the central arena had no effect on accuracy, but the use of adjacent arms increased significantly with a larger central arena, regardless of the size of arena to which rats were first exposed. These results are interpreted in terms of foraging efficiency.
The Bead Game: Response Strategies In Free Assortment, Alan B. Bond
The Bead Game: Response Strategies In Free Assortment, Alan B. Bond
Alan Bond Publications
Subjects were presented with a collection of spherical beads of four different colors and were instructed to sort them as fast and as accurately as possible. The sequence in which the beads were sorted was recorded, along with the time intervals between successive beads. Subjects were observed to sort in nonrandom sequences, producing runs in which a given bead type was taken exclusively. The speed and accuracy of the sorting process was positively correlated with the degree of nonrandomness of the sorting sequence. This relationship appeared to be primarily attributable to perceptual factors involved in the initiation of a run …
Evaluation Of Instream Flow Methodologies For Fisheries In Nebraska, Phil Hilgert
Evaluation Of Instream Flow Methodologies For Fisheries In Nebraska, Phil Hilgert
Nebraska Game and Parks Commission: Publications
Five instream flow methods were applied to a variety of streams within the state of Nebraska. These were (1) the Tennant method, (2) a modification of the Tennant method, (3) IFG1 A, a single cross-section average-parameter method, (4) the Incremental method, using the WSP hydraulic simulation program, and (5) the Incremental method, using the IFG4 hydraulic simulation program.
Each method was applied following standard published procedures, and instream flow recommendations were developed for the streams addressed using each method separately. Evaluation of the methods showed that the modification of the Tennant method overcame some of the deficiencies of the Tennant …
The Multi-Individual Cremation Phenomenon Of The Santa Cruz Drainage, Karl J. Reinhard, T Michael Fink
The Multi-Individual Cremation Phenomenon Of The Santa Cruz Drainage, Karl J. Reinhard, T Michael Fink
Karl Reinhard Publications
Multi-individual cremation deposits found in the upper Santa Cruz River drainage were previously interpreted as the result of hypothesized cultural contact in the area. A review of 50 cremation deposits for which detailed analyses are available indicates that mulii-individual cremation deposits are the result of incomplete gleaning practices and have doubtful cultural significance. Hypotheses are generated from the present data which account for the apparent variation in cremation practices within the study area.
