The Responses Of Ecologically Dissimilar Populations Of The Water Snake, Natrix Sipedon Sipedon To Surface Extracts Of Prey Species, With Observations On Feeding And Defense Behaviors, Doris Gove Dec 1971

The Responses Of Ecologically Dissimilar Populations Of The Water Snake, Natrix Sipedon Sipedon To Surface Extracts Of Prey Species, With Observations On Feeding And Defense Behaviors, Doris Gove

Masters Theses

Observations of defensive and feeding behavior of Natrix sipedon were made in the field and in the lab. Crypticity, mimicry of poisonous snakes, striking, production of cloacal secretion and tail autonomy were defensive behaviors discussed. Feeding behaviors discussed were hunting, catching prey and tongue-flicking.

Experiments were performed on the responses of snakes from ecologically dissimilar populations of N. sipedon to surface extracts of local prey species. The populations were: (1) a laboratory-reared litter of ten one-year-old snakes; (2) six wild-caught snakes from Sterchi's fish hatchery in north Knoxville, Tennessee; and (3) six wild-caught and eight newborn snakes (a litter ...


Second Specimen Of Oryzomys Dimidiatus, Hugh H. Genoways, J. Knox Jones Jr. Nov 1971

Second Specimen Of Oryzomys Dimidiatus, Hugh H. Genoways, J. Knox Jones Jr.

Mammalogy Papers: University of Nebraska State Museum

The species Oryzomys dimidiatus was originally named and described by Thomas (Ann. Mag. Nat. Hist., ser. 7, 15:584-591, 1905) as a member of the genus Nectomys on the basis of a single specimen from the Rio Escondido, 7 miles below Rama, Nicaragua ( approximately 1 km. S and 8½ km. E Ranla, 20 m, Zelaya), obtained by W. G. Palmer on 5 November 1904. Although there has been speculation on the relationships of this taxon (currently regarded as the only member of the subgenus Micronectmays, genus Oryzomys-see Hershkovitz, J. Mamm., 51:789-794, 1970, for review), the holotype has remained ...


The Seasonal Dietary Variation Of The Brook Stickleback (Eucalia Inconsians) In A Southeastern Wisconsin Stream, Roger Hlavek Oct 1971

The Seasonal Dietary Variation Of The Brook Stickleback (Eucalia Inconsians) In A Southeastern Wisconsin Stream, Roger Hlavek

Field Station Bulletins

The inter-relationship between predator and prey is often influenced by the season of the year. This concept has been noted by Hynes (1950) in two species of sticklebacks in England, Gasterosteus aculeatus, and Pygosteus pungitius, while Winn (1960) has reviewed the overall biology of the brook stickleback in Michigan streams. The present study has been undertaken to investigate the seasonal variations in diet exhibited by the brook stickleback.


Some Observations On Corticolous Cryptogams, William J. Woelkerling Oct 1971

Some Observations On Corticolous Cryptogams, William J. Woelkerling

Field Station Bulletins

The reliability of direction finding, as stated in the old adage-"moss grows best on the north sides of trees"-is subject to various interpretations. A personal evaluation of the reliability of this adage was attempted in a study of the corticolous cryptogams (non-seed plants which grow on the bark of trees) at The University of Wisconsin-Milwaukee Cedar-Sauk Field Station and adjacent Cedarburg Bog. In this study the trees were inspected not only for the presence of the true mosses but also for algae, fungi, lichens and liverworts. The results summarized in this report are based on observations of over ...


Productivity Of An Urban Park, Mary Herte, Nic Kobriger, Forest Stearns Oct 1971

Productivity Of An Urban Park, Mary Herte, Nic Kobriger, Forest Stearns

Field Station Bulletins

We have moderately good knowledge of the yields of crops and of commercial forest land. In contrast, little is known of the productivity of urban park areas. Parks are neither grassland nor forest-in structure they most closely resemble savanna, i.e., grassland spotted with trees bearing large crowns. How much energy is trapped by these communities? How much oxygen is liberated? What are the water requirements and recharge potentials of such areas? How can vegetation be best managed to promote the aesthetic and recreational needs of the urban citizen-and at the same time maintain its vital function as a living ...


Distribution Of Ferns In The Maple-Beech Forest At The Cedar-Sauk Field Station, Theodore E. Carlsen Oct 1971

Distribution Of Ferns In The Maple-Beech Forest At The Cedar-Sauk Field Station, Theodore E. Carlsen

Field Station Bulletins

This report is another in a series of plant studies under investigation at the UWM Cedar-Sauk Field Station. Most of the previous studies were concerned with seed plants and only limited attention was given to the fern flora. In this study, carried out chiefly in the summer of 1970, the fern species were evaluated to determine their importance, distribution and ecological relationships in the maple-beech forest.

A Flora From The Dakota Sandstone Formation (Cenomanian) Near Westwater, Grand County, Utah, Samuel R. Rushforth Sep 1971

A Flora From The Dakota Sandstone Formation (Cenomanian) Near Westwater, Grand County, Utah, Samuel R. Rushforth

Brigham Young University Science Bulletin, Biological Series

A Cretaceous (Cenomanian) flora from the Dakota Sandstone Formation near Westwater, Grand County, Utah contains an admixture of ferns and angiosperms. The ferns of this flora are representative of an older Jurassic-Wealden vegetational type, whereas the angiosperms are typical of the modern vegetational type. Species of Gleichenia and Matonidium and Astralopteris coloradica represent the dominant forms in this flora.

The Westwater flora contains fourteen genera including nineteen species and one variety. New species described from this flora include Asplenium dakotensis, Coniopteris westwaterensis and Ilex serrata.

Notes On The Biology Of The Central American Squirrel, Sciurus Richmondi, J. Knox Jones Jr., Hugh H. Genoways Jul 1971

Notes On The Biology Of The Central American Squirrel, Sciurus Richmondi, J. Knox Jones Jr., Hugh H. Genoways

Mammalogy Papers: University of Nebraska State Museum

Additional specimens of Sciurus richmondi are reported, along with comments on variation, distribution, reproduction and molt in this little known squirrel. As presently understood, S. richmondi occurs only in the Caribbean rain forests of Nicaragua. Significant secondary sexual variation in adults was found only in zygomatic breadth, in which females are the larger. Available evidence reveals that the breeding season extends at least from February to September, and suggests two seasonal molts annually.


A New Species Of Spiny Pocket Mouse (Genus Liomys) From Jalisco, Mexico, Hugh H. Genoways Jun 1971

A New Species Of Spiny Pocket Mouse (Genus Liomys) From Jalisco, Mexico, Hugh H. Genoways

Mammalogy Papers: University of Nebraska State Museum

In the course of a systematic revision of the spiny pocket mice of the genus Liomys, a series of large, brightly colored mice from several localities in southeastern Jalisco was studied. Individuals in this series appeared to be morphologically distinct from mice typical of Liomys pictus plantinarensis Merriam. 1902, taken in the same traplines at several localities, and from specimens of Liomys irroratus jaliscensis (J. A. Allen, 1906), a taxon that also occurs in southeastern Jalisco. The current studies now have progressed to the point where the large and distinctively colored mice from Jalisco can be defined as a new ...
