The Feeding Habits Of Gambusia Affinis Affinis, With Special Reference To The Malaria Mosquito, Anopheles Quadrimaculatus, A.D. Hess, Clarence M. Tarzwell
United States Environmental Protection Agency: Publications
The viviparous top minnow, Gambusia affinis affinis (Baird and Girard), has for many years been considered an important predator of the immature stages of mosquitoes. Various field workers have reported on the value of this species in controlling both anopheline and culicine mosquitoes, but few detailed studies have been made. Probably the most detailed of these has been that of Hildebrand (1925). His investigations were made during the summers of 1921-24 in the vicinity of Augusta, Ga., with the subspecies G. affinis holbrooki. Employing the common dipper method, he compared the densities of anopheline and culicine larvae and pupae in …

The Comparative Ability Of The Bob-White And The Ring-Necked Pheasant To Withstand Cold And Hunger, Paul L. Errington
The Comparative Ability Of The Bob-White And The Ring-Necked Pheasant To Withstand Cold And Hunger, Paul L. Errington
Other Publications in Wildlife Management
The native Bob-white (Colinus virginianus) and the introduced Ring-necked Pheasant (Phasianus colchicus torquatus) may both, on occasion, suffer severe winter mortality over much of their common range in north-central United States. Their habitats often overlap, although the Pheasant has a greater cruising radius and an ability to live in a more open type of country than the Bob-white. In given localities they also live upon much the same kinds of winter foods.
The scope of this paper is not intended to cover the ecological adjustments of Pheasants or of Bob-whites to their winter environment so much …

United States Geological Survey: Water Reports and Publications
Introduction
The purpose of this survey was to obtain information concerning existing wells and springs and the quantity and quality of water they yield, and to put down test holes where additional information was needed.
This project was part of a statewide Works Progress Administration project known as a "Statewide Inventory of Water Wells," sponsored by the [Texas] State Board of Water Engineers. The Division of Ground Water of the United States Geological Survey cooperated in the technical direction of the project and the Bureau of Industrial Chemistry of the University of Texas furnished laboratory space and equipment and supervised …

Bird Studies Of The Bear River Marshes, Ernest W. Parkinson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The establishment of the Bear River Bay Bird Refuge has created for the state of Utah an immense and valuable biological field, a veritable paradise for naturalist and sportsman alike. The naturalist wants a place to study wild life and the sportsman desires game. With the proper control of open seasons on wild fowl the hunting instinct and incentive for the sport should be satisfied for the sportsman. To the naturalist this region will open up bountiful treasures of knowledge that is to be gained only by intense and prolonged scientific study.

A Study Of The Vegetation Of Northeastern Arizona, Herbert Christian Hanson
University Studies (University of Nebraska) (1888–1984)
The State of Arizona is marked by a great series of cliffs that extend from the mouth of the Grand Canyon of the Colorado River in the northwestern part of the state southeastward into New Mexico. This line of cliffs, rising 1000 to 4000 feet above the desert plains forms the southwestern and southern boundary of the great physiographic province called the Colorado Plateaus. It is roughly circular and includes northeastern Arizona, northwestern New Mexico, western Colorado, and a large part of Utah. This province is subdivided by a number of deep canyons and high cliffs into numerous plateaus. The …

Bulletin 115 - The Value Of Windmills For Pumping Water In Western Australia, A. H. Scott
Bulletin 115 - The Value Of Windmills For Pumping Water In Western Australia, A. H. Scott
Bulletins 1 - 2999
It is surprising to note the dearth of up-to-date reliable information dealing with actual results of modern windmills, under working conditions, though literature on thousands of other subjects less important can usually be obtained.
In this bulletin there is presented a complete and accurate record of the amount of water pumped daily by a windmill, under actual working conditions, for a period of 14 months.

Bulletin No 81 - The Improvement Of Pastures With Notes On The Pasture Trefoils In Western Australia, E. A. Mann, D. A. Herbert
Bulletins 1 - 2999
Agriculture can be roughly divided for practical purposes into two large divisions, those of animal husbandry and vegetable husbandry. It is with the former that this pamphlet is chiefly concerned and its object is to contribute, it possible, in some small measure towards the problem of how to increase time stock carrying capacity of our natural pasture lands. it is unnecessary to dwell upon the importance of this question, especially in relation to the remarkable developments which are taking place in time wool-growing industry in the Southern and more coastal areas of Western Australia.

THE PROBLEM OF OUR SOILS AND SOIL MOISTURE.
The soil survey of the state, which was begun by the author in November of 1892, has progressed to the point where it might be considered finished. That is, one or more samples of soils have been taken from every distinct soil region in the state-in fact, most of the separate counties are represented, and mechanical analyses of many of these have already been made. However, in consideration of the size of our counties, the work will not be declared complete until each is represented in the state museum by soil prisms …
