Observations On The Conservation Of The Chesapeake Blue Crab, Callinectes Sapidus Rathbun, Curtis L. Newcombe, Ellen H. Gray

VIMS Articles

It is a matter of common knowledge among conservationists that the blue crab supply of the Chesapeake is rapidly declining, being reduced from a level of about 17 millions in 1931 to that of about 10 million crabs in 1937. (Md. Rept. 1937). Numerous explanations have been advanced to account for this decline. One outstanding reason is the taking of such large numbers of "sponge" (berried) crabs and mated female crabs, a practice which undoubtedly reduces the potential supply of young crabs for the ensuing year.

Another menace to the survival of the blue crab lies in the way in …

Common Birds Of Southeastern United States In Relation To Agriculture, F. E. L. Beal, W. L. Mcatee, E. R. Kalmbach

United States Fish and Wildlife Service: Publications

From a purely practical point of view the most important of the relations of native birds to man are the economic. The esthetic value of birds is great, greater indeed than that of any other group of animals; and that this is a real and especially a treasured value is not to be denied. But it is in their relation to insect and other enemies of crops that birds are most directly associated with the welfare of mankind, and their value in this particular should be made as widely known as possible. This bulletin is one of a series designed …

Wildlife Of The Atlantic Coast Salt Marshes, W. L. Mcatee

United States Fish and Wildlife Service: Publications

Salt marshes of the Atlantic coast have been formed under the opposed tendencies of sinking of the land and of its upbuilding by silt and sand. The plants that form the marshes occupy zones largely determined by the degree of inundation by tides. Eelgrass entirely submerged, smooth cordgrass regularly washed by the tide, and marsh hay covered only by exceptionally high water are characteristic plants. Each zone is the home or feeding area of certain kinds of wildlife. The appearance, distribution, and habits of the more common species are described, and general wildlife conservation is urged. This circular, which is …

A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard

Bulletin of the University of Nebraska State Museum

Since the Amebelodontinae were first announced (Barbour 1927), a number of examples of the genus Amebelodon have presented themselves in various parts of Nebraska, Colorado, and in several places in Kansas. Thus its range has already been materially extended, many skeletal parts added, and the hope kindled that knowledge of this remarkable group of proboscideans is destined to be greatly enriched within the next few years. As may be seen in the accompanying lists of the known parts of Amebelodon preserved in various museums, there are already at hand the bones necessary for the assemblage of a nearly complete composite …

Conserving Our Salt-Water Fisheries: Work Of The Virginia Fisheries Laboratory, Curtis L. Newcombe

VIMS Articles

Even the casual visitor to many of our small Tidewater Virginia fishing communities will see signs of diminishing prosperity. A prosperous era has been succeeded by a period of lower economic and social levels.

What are the underlying causes of this declining trend? In facing this problem, so broad in its scope and so serious in its effect, the Virginia Fisheries Laboratory has, during the past year, effected an organization for analyzing conditions in our commercial fisheries and for disseminating facts about them and the need for their conservation.

Noteworthy Arkansas Plants, Delzie Demaree

Journal of the Arkansas Academy of Science

The above list of fifty plants was presented before the Arkansas Academy meetings at Conway, 1939, Fayetteville, 1940, and at Arkadelphia, 1941. Eleocharis quadrangulata is the only one previously listed in an Arkansas check list, but no locality was given. It is not known by the writer from any other station than the above. The list comprises thirty-five genera, forty-eight species, twenty-six varieties, one form, and one hybrid.

New Species Of Ground Beetle Of The Genus Rhadine From An Arkansas Cave (Coleoptera: Carabidae), Milton W. Sanderson, Albert Miller

Journal of the Arkansas Academy of Science

Rhadine ozarkensis is described as a new species of ground beetle from Fincher's Cave, Washington County, Arkansas. Two males and three females were collected in the twilight and total darkness zones between November 4, 1939 and January 20, 1940, form three liver baited traps set in the cave floor. This species is related to R. caudata (Lec.)

Phylogenetic Studies On The Blood-Inhabiting Trematodes, Harold Frederick Dieckmann

University of the Pacific Theses and Dissertations

Trematodes belonging to the blood-inhabiting group have long attracted the attention of parasitologists and medical men, especially those trematodos belonging to the family Schistosomidae because throw widely distributed species, Schistosoma Japonicum, S. haematobium, and S. mansoni, are parasitic in man, and in endemic regions are the cause of important human diseases. These schistosomes, with a few exception, have undergone more detailed research than any other trematodes.

Since the discovery of the first digenetic trematode exhibiting sexual dimorphism by Rudolphi (1819), which was named Distoma canaliculatum, and the descriptions of the other blood flukes up until the present time, a vast …

Bulletin No. 295 - Comparison Of Two Methods Of Determining Wool Density, Milton A. Madsen, Ralph W. Phillips, John V. Christensen, Roy L. Henrie

UAES Bulletins

Density of the fleece is one of the primary factors determining the wool-producing capacity of the sheep. Sheepmen have attempted to evaluate density by handling the fleece. This method is not sufficiently refined for use in experimental work, and may be subject to errors and misinterpretations. For example, if two fleeces are alike in density and diameter of fibers, yet differ in length, the longer fleece will feel less dense. If, on this basis, the sheep with the fleece that appeared most dense were selected for breeding, selection would be away from the longer fleece. Any method that can be …

Trees And Shrubs Of Kings Canyon National Park, Kenneth M. Stocking

University of the Pacific Theses and Dissertations

In 1935 I first visited the Kings Canyon area. Since then I have spent many hours wandering through the woods and over the mountains in the area around the old General Grant National Park and the country which is now included in the Kings Canyon National Park. To my knowledge, no complete flora has been made for this vicinity. I consider the following pages to be the beginning of a fascinating work. It is the beginning because this paper includes only plants with woody stems.

Preliminary Report On The Legumes Of The Arkansas Uplands, Orrin J. Henbest

Journal of the Arkansas Academy of Science

A brief discussion is presented on the ecologic, taxonomic, and economic features of the leguminous plants of the uplands occupying the northwestern half of Arkansas. The list of 37 genera and 115 species is compiled from the author's collection and from the specimens in the herbarium of the University of Arkansas collected in this part of the state. The geographic position of this area and its variety of ecological habitats indicate that it may yield nearly 175 species of legumes.

A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

The genus Sphenophalos was described by John C. Merriam (1909, p. 319-30), who based his description on a fragmentary horn-core (Uni. of Calif. No. 11887) from the late Tertiary deposits near Thousand Creek in northern Humbolt county, Nevada. Knowledge of Sphenophalos, however, is still confined to this single, fragmented type horn-core (Frick 1937, p. 472) and other fragmental specimens (Furlong 1932, p. 27-36).
