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

University of Nebraska State Museum: Mammalogy Papers

The species Oryzomys dimidiatus was originally named and described by Thomas (Annals of the Museum of Natural History, series 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 November 5, 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, Journal of Mammalogy, 51: 789-794, 1970, …

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

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 2000 separate …

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.

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 filter? …

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

University of Nebraska State Museum: Mammalogy Papers

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

University of Nebraska State Museum: Mammalogy Papers

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 …

Systematics Of Southern Banner-Tailed Kangaroo Rats Of The Dipodomys Phillipsii Group, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Both nongeographic and geographic variation was assessed in southern banner-tailed kangaroo rats of the nominal species Dipodomys phillipsii and D. ornatus . Univariate and multivariate analyses were employed in consideration of geographic variation. D. ornatus is arranged as a subspecies of D. phillipsii, in which four races (phillipsii, ornatus, perotensis, and oaxacae) are recognized. Some observations on natural history also are included.

Systematic And Evolutionary Implications Of Parthenogenesis In The Hymenoptera, C. N. Slobodchikoff, Howell V. Daly

Entomology Collection

Two types of parthenogenesis, arrhenotoky and thelytoky, exist in the Hymenoptera. Arrhenotoky, the development of males from unfertilized eggs, is present in all wasps and bees. Thelytoky, the development of diploid females from unfertilized eggs, is present in a few species. Two types of thelytoky, apomixis and automixis, are known. Most thelytokous Hymenoptera are automictic. No meiosis, only mitosis, occurs in apomixis. Meiosis does occur in automixis, allowing crossing-over and segregation of genes. Advantages of thelytoky are that heterotic combinations become fixed, gene loss is reduced, and reproduction requires only a single individual. One advantage of arrhenotoky is that genetic …

Change In The Urban-Rural Ecotone, Paul E. Matthiae

Field Station Bulletins

Conversion of the rural Wisconsin landscape from farms to housing poses serious wildlife management and utilization problems. The problems are aggravated by the unregulated and unplanned nature of the land use changes. Purchase of farms for future development often results in removal of the entire farm from crop production. Occasionally the choicest tillable acres are rented or leased to a neighboring farmer, but even so, the remaining land is allowed to lie fallow and undergo old field succession. In a few cases pine plantations or wildlife food patches may be established or a pond constructed.

Dogwoods In Wisconsin, Peter J. Salamun

Field Station Bulletins

Many persons who have taken early spring trips to the southern and southeastern sections of our country frequently remark about the attractiveness of the Flowering Dogwood (Cornus florida L.) which they observed in the woodlands of this area. They also ask why this small tree does not grow in Wisconsin. According to the publication, "Growing the Flowering Dogwood" (USDA, 1970), this plant cannot be successfully grown where the winter temperatures go below -15°F; therefore, it is not considered hardy in our climate. We can take some solace, however, because there are a number of attractive native dogwoods which bloom in …

Mycological Research At The Field Station, John Baxter

Field Station Bulletins

During the past three years, several mycological research projects have been conducted partially at the Field Station or have used research material obtained at the Station. These include a study of cellulose-digesting fungi from soils of the area (Gatford, 1969), an investigation of lignin digestion by wood-rotting fungi collected at the Station (Flashinski, 1970), and life cycle studies of certain rust fungi of southeastern Wisconsin (Baxter, 1971). At the present time two new mycological research projects are being planned.

Population Dynamics Of The Black-Capped Chickadee, Charles M. Weise

Field Station Bulletins

The Black-capped Chickadee is an abundant, familiar bird in Wisconsin, known to almost everyone. In summer it is widespread in nearly all kinds of woods, although it is more numerous in younger second-growth forests, swamp forests or along forest-edges than in mature climax types. In winter, it becomes more restricted to dense thickets, bogs or swamps, especially where conifers like cedars or hemlocks occur; however, it also congregates in large numbers in towns or suburban areas wherever it can find artificially provided food at bird-feeding table. ecology. Since 1968 we have been concentrating our efforts more and more on a …

Urban Botany - An Essay On Survival, Forest Stearns

Field Station Bulletins

Botany is today's most needed urban science. It deals with life and with objects which man can understand, for which he reaches and with which he feels comfortable. The technological and economic problems of the city are horrendous—transportation, waste disposal, air pollution, and housing to name a few.

Morphological Variation In Stenoderma Rufum, J, Knox Jones Jr., Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

For more than 100 years, the red fruit-eating bat, Stenoderma rufum Desmarest, 1820, was known only by a specimen of unknown geographic provenience. Anthony ( 1918, 1925) rediscovered Stenoderma in Puerto Rican cave deposits, but the first living specimens to be reported since the original description were taken on St. John in the Virgin Islands (Hall and Bee, 1960). Subsequently, Tamsitt and Valdivieso (1966) recorded living representatives from Puerto Rico-from a population later named and described as a distinctive subspecies, Stenoderma rufum darioi, by Hall and Tamsitt (1968). The latter authors also reported a specimen of S. r. rufum …

Impoundment Effects On Water Quality As Reflected In Parasitism Of Reservoir Basses, David A. Becker

Technical Reports

Our aquatic environments are rapidly becoming useless as natural resources through pollution from various sources. It is therefore necessary for us to further understand the various means which relate to this process. The interrelationships between the physico-chemical and biological water qualities undergo marked changes during the ageing of a reservoir. Eutrophication of these impoundments render them rela-tively useless as natural resources. It thus becomes apparent that we must gain further knowledge of these processes if we are to devise methods for proper reservoir management.

Bibliography On The Scyphozoa With Selected References On Hydrozoa And Anthozoa, Dale R. Calder, Harold N. Cones, Edwin B. Joseph

Reports

Our goal in assembling this bibliography has been to bring together literature references on all aspects of scyphozoan research. Compilation was begun in 1967 as a card file of references to publications on the Scyphozoa; selected references to hydrozoan and anthozoan studies that were considered relevant to the study of scyphozoans were included. In 1968, a major research program on the jellyfish of Chesapeake Bay was initiated at the Virginia Institute of Marine Science (VIMS) under Dr. E. B. Joseph, and work on the bibliography became an integral part of the program. In 1969 we began converting the bibliography into …

Bacula Of Some Neotropical Bats, Randall E. Brown, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Neotropical bats representing 56 species of five families were examined for presence or absence of a baculum. Members of the families Noctilionidae and Phyllostomatidae (sensu lato) have no os penis, but the bone was found in all species studied of Emballonuridae, Natalidae, and Vespertilionidae. The bacula of seven emballonurids, one natalid, and seven vespertilionids are briefly described and figured.

The Distribution And Ecology Of The Gammaridea (Crustacea : Amphipoda) Of The Lower Chesapeake Estuaries, James Feely, Marvin L. Wass

Reports

Gammarid amphipods of three tidal rivers entering Chesapeake Bay were studied for ten months, particularly in the York River where 40 species were record during the period. Several species moved up or down the rivers with changing salinity. The more abundant species had longer breeding seasons. The number of described species from lower Chesapeake Bay is now 42 and the presence of 10 undescribed species and of several which bracket the region indicates that much remains to be learned about amphipods in the Bay. Nineteen of these have a boreal affinity and seven are limited to the Virginian subprovince. A …

Hydroids And Hydromedusae Of Southern Chesapeake Bay, Dale Calder

Reports

A survey was made in southern Chesapeake Bay and its tributaries from April 1965 through March 1968 to determine the species of hydrozoans present, their seasonality and reproductive periodicities. This report discusses 43 hydroid and 27 medusa species known from the study area, of which 23 hydroids and 11 medusae have not previously been found in Chesapeake Bay. Clytia paulensis and the hydroid of Moerisia lyonsi have not been reported before in North American waters, and the hydroid of Amphinema dinema is recorded for the first time from the western Atlantic. The present records extend the northern range of one …
