Morphological Variation In The Southeastern Pocket Gopher, Geomys Pinetis (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways Dec 1980

Morphological Variation In The Southeastern Pocket Gopher, Geomys Pinetis (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The nominal species of southeastern pocket gophers (Geomys pinetis, G. colonus, G. cumberlandius, and G. fontanelus), which collectively occupy a geographic range on the Atlantic and Gulf coastal plain of Alabama, Georgia, and Florida, were examined for morphological variation. Univariate and multivariate analyses were used to determine age, sexual, individual, and geographic variation in G. pinetis. Significant differences were found among different age classes and between sexes. Males displayed higher individual variation than females and external measurements were more variable than cranial measurements. Of the four named species in the pinetis-species group (colonus …


Karyology And Morphometrics Of Three Species Of Akodon (Mammalia: Muridae) From Northwestern Argentina, Rubén M. Barquez, Daniel F. Williams, Michael A. Mares, Hugh H. Genoways Dec 1980

Karyology And Morphometrics Of Three Species Of Akodon (Mammalia: Muridae) From Northwestern Argentina, Rubén M. Barquez, Daniel F. Williams, Michael A. Mares, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Chromosomal and morphometric studies were conducted on a sample from an assemblage of Akodon spp. occurring in various patterns of sympatry from the provinces of Catamarca, Jujuy, Salta, and Tucumán, Argentina. Results showed three distinct morphometric groups based upon size. Size also varied with age, but there were no significant differences in measurements of males and females. The three morphometric groups have distinct karyotypes. Akodon caenosus Thomas is the smallest of the three, and has a karyotype of 2n = 34, FN = 40. A. boliviensis tucumanensis J. A. Allen is intermediate in size and has 2n = 40, FN …


Results Of The Alcoa Foundation-Suriname Expeditions. Iv. A New Species Of Bat Of The Genus Molossops (Mammalia: Molossidae), Stephen L. Williams, Hugh H. Genoways Dec 1980

Results Of The Alcoa Foundation-Suriname Expeditions. Iv. A New Species Of Bat Of The Genus Molossops (Mammalia: Molossidae), Stephen L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

A new species of molossid bat of the genus Molossops is described from Suriname. The new species is a member of the subgenus Molossops where it is distinguished from the other two member species, temminckii and aequatorianus, by larger external and cranial size. A single specimen of the species was taken in northern Suriname in an area of savannah and secondary forest.

NOTES

MOTTLED DUCK. On 5 October 1958 I shot but just winged a female Mottled Duck. This was in Howard Co., on the Loup River, which borders our farm. I kept her (which was legal at the time), got a drake from Texas, and had them for years. I reared many young from the pair.

Stress: What Is It And How Can It Be Quantified?, T. H. Friend Nov 1980

Stress: What Is It And How Can It Be Quantified?, T. H. Friend

International Journal for the Study of Animal Problems

An animal may be considered to be in a state of stress if abnormal behavior or extreme adjustments in its behavior or physiology are necessary in order to cope with adverse aspects of its environment. Methods used to determine if an animal is stressed can be either behavioral or physiological. Behavioral methods may be highly erroneous due to their subjective nature since alterations in behavior do not necessarily prove that an animal is stressed. There is no single measure of stress that can be used in all situations at this time. Every measure must be critically evaluated to ensure that …

Problems With Kosher Slaughter, Temple Grandin Nov 1980

Problems With Kosher Slaughter, Temple Grandin

International Journal for the Study of Animal Problems

Ritual slaughter to produce kosher meat is rooted in the teachings and writings of the Talmud. However, the preslaughter handling features of modern systems, particularly the shackling and hoisting of large steers, contravene the basic message of humaneness included in the teachings. The throat-cutting of a live, conscious animal is relatively pain-free, provided that certain precautions are followed, but U.S. kosher plants need to install newly developed conveyor-restrainer systems to eliminate the abuses of shackling and hoisting. Conveyor-restrainer systems for large and small animals are discussed.


Vegetative Community Descriptions For The North Platte River In Wyoming And Nebraska, Lynn Fisher Nov 1980

Vegetative Community Descriptions For The North Platte River In Wyoming And Nebraska, Lynn Fisher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

A description of the vegetative communities in an area will provide an insight to wildlife potential and use of that area. Wildlife and its corresponding habitat are recognized as important for recreation and to the overall environmental quality of an area. The Water and Power Resources Service, Lower Missouri Region, is presently engaged in a study of the Platte River Basin, including an evaluation of wildlife habitat and associated environmental needs. Quantification of wildlife habitat along the South Platte River has been completed. Vegetation communities were described and habitat maps were prepared from color infrared aerial photographs (scale – 1:24,000). …

Latitudinal Variation In The Relationship Between Rosette Diameter And Fate In Common Mullein (Verbascum Thapsus L.), James A. Reinartz Oct 1980

Latitudinal Variation In The Relationship Between Rosette Diameter And Fate In Common Mullein (Verbascum Thapsus L.), James A. Reinartz

Field Station Bulletins

There is currently a good deal of interest in the "biennial" life history. This stems from the fact that theoretical analysis of the selective advantage of alternate life histories predicts that biennials should seldom be favored relative to annual or perennial alternatives (Hart, 1977). However biennials often appear highly successful in terms of abundance, being both common and widespread, even though they constitute only a small proportion of any flora. This paper describes the effects of latitude on the relationship between rosette diameter at the end of one growing season and a plant's fate in the next (death, continued vegetative …


Primary Production In Wild And Cultivated Cranberries, Mark Walstrom, Forest Stearns Oct 1980

Primary Production In Wild And Cultivated Cranberries, Mark Walstrom, Forest Stearns

Field Station Bulletins

Cranberries grow in many Wisconsin sphagnum bogs. One of the two species, the large cranberry, Vaccinium macrocarpon Alt., is among the few American fruit crops in cultivation. Most of the cultivated cranberries have been derived by selection from wild, and more recently from cultivated clones. Like the large cranberry, the small cranberry, Vaccinium oxycoccos L., is native to Wisconsin bogs and it, too, provides wildlife food, though it has not been selected for cultivation. This study examined the primary productivity of wild and cultivated cranberries (Wahlstrom 1979).


Seasonal Activity Patterns In The Bat Community At Neda Mine, Charles Rupprecht Oct 1980

Seasonal Activity Patterns In The Bat Community At Neda Mine, Charles Rupprecht

Field Station Bulletins

Even though bats represent a relatively abundant, biologically fascinating and highly beneficial component of Wisconsin's wildlife, they remain poorly studied and greatly misunderstood. Accounts of the seasonal adaptive strategies of most bats are inadequate or fragmentary (Barbour and Davis 1969). Rarely have researchers investigated more than one species at a single time and place. The aim of this study was to make simultaneous comparisons by sex and species of the various adaptive strategies employed by members of the Neda Mine bat community on an annual basis.


Transpiration And Co2 Fixation Of Selected Desert Shrubs As Related To Soil-Water Potential, S. B. Clark, J. Letey Jr., O. R. Lunt, A. Wallace, G. E. Kleinkopf, E. M. Romney Oct 1980

Transpiration And Co2 Fixation Of Selected Desert Shrubs As Related To Soil-Water Potential, S. B. Clark, J. Letey Jr., O. R. Lunt, A. Wallace, G. E. Kleinkopf, E. M. Romney

Great Basin Naturalist Memoirs

In desert plants, transpiration rates decreased before photosynthetic rates when plants were entering a period of water stress. This may have adaptive consequences. A difference of -5 bars in the soil-moisture potential had considerable importance in reducing the rate of transpiration. In Helianthus annuus L. (sunflower) the photosynthetic rate decreased before the transpiration rate in contrast to Great Basin-Mojave Desert plants, and the changes occurred with a -1 bar difference in soil-moisture potential. Morphological changes in three desert plant species [Artemisia tridentata Nutt., Ambrosia dumosa (Gray) Payne, Larrea tridentata (Ses. Moc. ex DC) Cov.] as the soil-moisture potential decreased …

Mineral Compostition Of Atriplex Hymenelytra Growing In The Northern Mojave Desert, A. Wallace, E. M. Romney, R. B. Hunter, J. E. Kinnear, G. V. Alexander

Great Basin Naturalist Memoirs

Fifty samples of Atriplex hymenelytra (Torr.) S. Wats, were collected from several different locations in southern Nevada and California to test variability in mineral composition. Only Na, V, P. Ca, Mg, Mn, and Sr in the samples appeared to represent a uniform population resulting in normal curves for frequency distribution. Even so, about 40 percent of the variance for these elements was due to location. All elements differed enough with location so that no element really represented a uniform population. The coefficient of variation for most elements was over 40 percent and one was over 100 percent. The proportion of …
