Comparison Of Spider Populations Of Ground Stratum In Arkansas Pasture And Adjacent Cultivated Field, W. H. Whitcomb, Harriet Exline, Maxine Hite

Journal of the Arkansas Academy of Science

Of 64 species of spiders taken from the ground stratum of an Arkansas pasture and adjoining cotton field, only 26 were common to both. Twenty-two were collected only in the cotton field; 16, only in the pasture. Many of the 18 species of lycosids were taken in greater numbers in the cultivated field, especially Pardosa milvina and Lycosa helluo. Eight species of lycosids were found only in the cotton field; two, only in the pasture. Only Schizocosa avida, of the better represented lycosids, appeared to show no preference. Similar relationships are given for dictynids, erigonids, linyphiids, oxyopids, gnaphosids, clubionids, thomisids, …

Grazing To Control Pasture Composition, R A. Bettenay

Journal of the Department of Agriculture, Western Australia, Series 4

APART from grazing management, there are a number of means by which the farmer can influence pasture composition.

With the exception of grazing, all of these processes involve recurring costs, so it is important to exert the utmost possible control through the grazing animal.

Journal of the Department of Agriculture, Western Australia, Series 4

A GOOD knowledge of the nectar producing plants of the State is essential for success in commercial beekeeping.

The Romney Marsh, J A. Mallett

Journal of the Department of Agriculture, Western Australia, Series 4

THE Romney Marsh, sometimes known as the Kent, is the most popular of the British longwoel sheep breeds used in Western Australia.

Rams of this breed are widely used for mating with Merino ewes, the crossbred female progeny of the matings being in demand for subsequent mating with Downs-type rams to produce export Iambs.

Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson

Nebraska Game and Parks Commission: Publications

The purpose of this booklet is to provide a ready field reference for identification, sexing and aging of common game species. It has purposely been kept in simplified form, presenting only those techniques which can commonly be applied in the field and avoiding those which would require special equipment and skills. Untrained personnel should be given demonstrations of the techniques, and thereafter this reference should serve as a reminder. It is not expected that the reference could successfully be used without such demonstration. Certain of the techniques such as cloaca! examination of waterfowl may require considerable practice by the individual. …

Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard

Nebraska Game and Parks Commission: Publications

IN COMMON with the experience of most states, Nebraska's deer herds were reduced to a very low level by excessive harvests in our early history. Most American big-game animals were overharvested in the early history of this nation because of commercialization. Buffalo were killed for their hides, deer for their meat. This slaughter continued as long as the hunter (or poacher) could sell his take at a profit. Modem game management and public opinion reversed this trend. Deer are on the way back all over America, and in some states the protection-complex was so strong that deer were restored to …

Life Histories Of North American Nuthatches, Wrens, Thrashers And Their Allies: Order Passeriformes, Arthur Cleveland Bent

Papers in Ornithology

An attempt has been made to give as full a life history as possible of the best-known subspecies of each species and to avoid duplication by writing briefly of the others and giving only the characters of the subspecies, its range, and any -habits peculiar to it. In many cases certain habits, probably common to the species as a whole, have been recorded for only one subspecies. Such habits are mentioned under the subspecies on which the observations were made. The distribution gives the range of the species as a whole, with only rough outlines of the ranges of the …
