Flora Of Nebraska: Part 21. Rosales, Per Axel Rydberg, The Botanical Seminar, University Of Nebraska
Flora Of Nebraska: Part 21. Rosales, Per Axel Rydberg, The Botanical Seminar, University Of Nebraska
School of Biological Sciences: Faculty Publications
DeCandolle, the author of Calyciflorae, gives the following characters (Prodromus, 2: 1): “Calyx gamosepalous, that is, the sepals more or less united at the base. Torus more or less adnate to the bottom of. the calyx. Petals and stamens inserted on a torus which is partly adnate to the calyx, and therefore geuerally said to be borne on the calyx. Petals free or united with each other. Ovary free, or adnate to the calyx.”
What has generally been regarded as the lower portion of the gamosepalous calyx, and is described as such in many recent systematic works, is in reality …
The Earliest Name For Steller's Sea Cow And Dugong, Theodore S. Palmer
The Earliest Name For Steller's Sea Cow And Dugong, Theodore S. Palmer
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
In 1811, Illiger published a number of new genera, proposing among others, Rytina for the sea cow of Bering Island and Halicore for the dugong of the Indian Ocean. Nearly all recent writers on mammals have adopted these genera, apparently overlook ing the fact that both animals had been named before 1811. As early as 1794 Retzius described the sea cow in the 'Handlingar' of the Stockholm Academy of Science, placing it in a new genus which he called Hydrodamalis, and the species, based on the Vacca marina of Steller, Hydrodamalis stelleri. The generic description is sufficient to …
The Parasitic Worms Of Man And The Domestic Animals, Henry B. Ward
The Parasitic Worms Of Man And The Domestic Animals, Henry B. Ward
Studies from the Zoological Laboratory: The University of Nebraska
This article has been written for the general information of those engaged either on a large or on a small scale in stock raising in our own state particularly, and, while not intended to be a complete treatise on the subject, it includes references to those parasites which seem to be the most important or most likely to be found within our borders. The parasites of cattle, sheep, horse, hog, dog, cat, and man, which have many species in common, form the subject of this paper. The parasites of domestic fowl are, however, quite different from those considered here and …
On Distoma Felineum Riv. In The United States And On The Value Of Measurements In Specific Determinations Among The Distomes, Henry B. Ward
On Distoma Felineum Riv. In The United States And On The Value Of Measurements In Specific Determinations Among The Distomes, Henry B. Ward
Studies from the Zoological Laboratory: The University of Nebraska
The distomes of cats have received special attention of late in the two papers of Braun (94) and Stiles and Hassall (94). The latter authors give a most admirable account of our present knowledge of a dozen allied forms, and record two, D. albidum and D. complexum n. sp., as found in cats in the United States. During the past year I have examined the cats killed at this laboratory, and have found neither of the forms recorded from the east. Distoma felineum, however, which Stiles and Hassall did not find. and which has not been reported hitherto for …
A New Method For The Quantitative Determination Of Plankton Hauls, Henry B. Ward
A New Method For The Quantitative Determination Of Plankton Hauls, Henry B. Ward
Studies from the Zoological Laboratory: The University of Nebraska
Only two methods of estimating the quantity of plankton obtained in a haul of the vertical net are known to me. These two may be called the volumetric and the gravimetric. Both have been used by observers in various parts of the world, but so far as I know have never been comparatively tested in order to ascertain the relative value of results obtained by the two. The experience of the past year has shown some disadvantages in the first method, while the second has certain evident objections which rendered its employment in this case out of the question. In …
Lincoln Salt Lake And The Occurrence Of Strepsilas Interpres, Erwin Hinckley Barbour
Lincoln Salt Lake And The Occurrence Of Strepsilas Interpres, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
Local ornithologists are considerably interested in the occurrence of the Turnstone (Strepsilas interpres) in this State. Three were shot at Lincoln Salt Lake on the 25th of May of this year. These were secured by Mr. W. D. Hunter of the Department of Taxidermy, and were placed by him in the State Museum. This is the first authentically reported occurrence of this bird in Nebraska. So far as we can learn it is not reported for any of our neighboring States.
Is Daemonelix A Burrow?: A Reply To Dr. Theodor Fuchs, Erwin Hinckley Barbour
Is Daemonelix A Burrow?: A Reply To Dr. Theodor Fuchs, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
Dr. Theodor Fuchs, criticises at considerable length the nature of Daemonelix as described by the author, in the University Studies, of the University of Nebraska, Vol. I, No. 4, July, 1892, under the title, 'Notes on a New Order of Gigantic Fossils.' When the criticism first appeared it seemed so fraught with errors that they were counted its own best rebuttal, and no attempt to frame a reply was thought of. However, the author has several times of late been reminded that these errors might pass muster and become fixed in the minds of those, at least, who place too …
Report Of A Botanical Exploration Of The Sand-Hill Region Of Central Nebraska Made In The Summer Of 1893., Per Axel Rydberg
Report Of A Botanical Exploration Of The Sand-Hill Region Of Central Nebraska Made In The Summer Of 1893., Per Axel Rydberg
School of Biological Sciences: Dissertations, Theses, and Student Research
Rydberg (1860–1931) was born Sweden and emigrated to the United States in 1882, first to mining camps in upper Michigan and eventually to Wahoo, in Saunders County, Nebraska, where he taught mathematics from 1884 to 1893 at now defunct Luther Academy. In the summers of 1891-1893, 1895, and 1896 he was a field agent for the United States Department of Agriculture and collected plants in Nebraska, South Dakota, Montana, Idaho, Wyoming, and Colorado, and specimens from those and other trips are in the Bessey Herbarium at the University of Nebraska–Lincoln, which house what is now known as the Charles E. …
The Asiatic Lung-Distome In The United States, Henry B. Ward
The Asiatic Lung-Distome In The United States, Henry B. Ward
Studies from the Zoological Laboratory: The University of Nebraska
In 1893 I reported the occurrence of the Asiatic distome in the lungs of a cat examined in Ann Arbor, Mich. This was the first reported find of this species on this continent, and the possibility of its being a permanent guest in this country was so serious that I urged a careful examination of all cases of lung-parasites in the domestic animals, with a view to ascertaining whether this might be an isolated instance, or whether the parasite was actually established within our land, for it is true that the Chinese, among whom the parasite is very common, regard …

Report Of The Zoologist, Henry B. Ward
Report Of The Zoologist, Henry B. Ward
Studies from the Zoological Laboratory: The University of Nebraska
In the report of last year was given a full summary of the present state of our knowledge concerning the parasites of man and the domestic animals. It is the intention of the following pages to review the parasitic fauna of the state of Nebraska so far as it is definitely determined, and also to include a list of some species reported but not accurately identified. The second section of this report presents a brief description of some important parasites not included in the group of worms, and hence not mentioned in last year's report. I shall omit all parasites, …
A Second Case Of Distoma Westermanni In The United States, Henry B. Ward
A Second Case Of Distoma Westermanni In The United States, Henry B. Ward
Studies from the Zoological Laboratory: The University of Nebraska
In a previous number of the Veterinary Magazine, I have given an account of the discovery of Distoma westermanni in the lungs of a cat at Ann Arbor. The importance of the discovery within our country of this dangerous parasite. so common in the East, was emphasized, and an appeal was made for more information as to the presence of lung distomes in various hosts in the United States since, as stated (p. 357), “there is no need of emphasizing the importance of obtaining accurate knowledge as to the extent of the infection among animals, and even man;” . …
The Food Supply Of The Fish In The Great Lakes, Henry B. Ward
The Food Supply Of The Fish In The Great Lakes, Henry B. Ward
Studies from the Zoological Laboratory: The University of Nebraska
When the early settlers made their homes along the shores of the Great Lakes, the waters of these inland seas teemed with fish. A cheap and apparently inexhaustible supply of food lay within easy reach, and they drew from it unstinted, nor was it strange that, with the increasing population and ever-widening means of communication, delicacies so tempting as the whitefish and lake trout were eagerly sought after in the markets of the neighboring cities, and that the ingenuity of generations of fishing folk was taxed to invent means of securing the fish-until finally, in the face of a growing …
