History Of The State Vermin Barrier Fences, Formerly Known As Rabbit Proof Fences, J S. Crawford

Research Reports

There is evidence of rabbits arriving in Australia as far back as 1788, and it is well known that others were liberated on islands around the coast, including some off the coast of Western Australia. However, they remained localised and it is now generally accepted that the rabbits which did spread originated from a small shipment of the wild type brought on the Clipper “Lightning” in 1859. They were released on “Barwon Park”, the property of Thomas Austin, near Geelong in Victoria, and within three years, had reached pest proportions

Some Parameters Of The Second-Order Conditioning Of Fear In Rats, Alan Kamil

Papers in Behavior in Biological Sciences

The effects of CS1 duration, partial reinforcement, and trace conditioning on second-order conditioned suppression were investigated, employing 64 rats as Ss. In Experiment 1, the clearest second-order conditioning was obtained when CS1 duration was the same during both the first- and the second-order conditioning phases of the experiment. In Experiment 2, somewhat better second-order conditioning was obtained when first-order conditioning had been under conditions of partial reinforcement, delay CS-US pairing. In neither experiment were CS1 suppression and CS2 suppression during second-order testing well correlated. This aspect of the results raised the question of the influence of nonclassical conditioning factors on …

Anemonala californica (Nutt.) Hook and Arn.(family Saururaceae), commonly known as Yerba del Hanza, is widely distributed in the United States and northern provinces of Mexico. The extract of the roots and rhizomes is used by the natives of Mexico in the treatment of rheumatic disorders, for asthma and also as a blood purifier.

Distribution Of The Porcupine, Erethizon Dorsatum, In Mexico, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The first Recent record of the porcupine, Erethizon dorsatum, from Mexico comprised fragmentary remains associated with human occupancy from a cave east of Cuatro Cienegas, Coahuila (Gilmore, 1947: 158-159). Later, Benson (1953 : 511-512) reported two specimens from western Sonora from < the lower flood plain of the Rio Sonora, close to the Gulf of California >> (one from 6 miles N Puerto Kino and the other from Rancho Santa Ana, about 45 miles W Hermosillo), and Dickerman (1962: 108) recorded the species from Hda. Las Margaritas in northern Coahuila. No additional reports of Recent porcupines from Mexico have come to our attention, and four specimens of Erethizon dorsatum couesi Mearns, 1897, in the Museum …

Some Observations On Maccoa Duck Behaviour, Paul A. Johnsgard

Paul Johnsgard Collection

The recent comprehensive review of Maccoa Duck Oxyura maccoa biology by Clark (1964) has provlded the first detailed summary of the species' reproductive behaviour patterns and other aspects of breeding in this little-studied stiff-tail. It has been evident that the evolutionary relationships of the Maccoa Duck to the other southern hemisphere stiff-tails and the northern species of Oxyura are still uncertain at best, as evidenced by the varied taxonomic treatment that the Maccoa has received from Delacour and Mayr (1945), who regarded it as a race of O. australis, from Boetticher (1952), who consldered it as a race of O. …

Mourning Dove Status Report, 1967, James L. Ruos, Duncan Mcdonald

United States Fish and Wildlife Service: Publications

Nationwide dove population indexes in the 1967 Mourning Dove Status Report were obtained by essentially the same data gathering and analyzing procedures as in 1966. A refinement was made in the base year index, using the mean of the 1966 and 1967 readings as the base for all States. There was a slight adjustment in physiographic region boundaries.

Notes On Bats From The Mexican State Of Zacatecas, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Much of the Mexican state of Zacatecas lies in the area ascribed to the Mexican Plateau. Along the western border and in the southwest, however, the state encompasses a portion of the Sierra Madre Occidental, and perhaps more importantly, from a zoogeographic view, the Rio Juchipila, a major tributary of the Rio Grande de Santiago, drains the southern "panhandle." The valley of the Juchipila supports tropical vegetation as perhaps do the valleys of several other smaller tributaries of the Rio Grande that barely reach the southern part of the state. The setting of southern Zacatecas suggests, therefore, considerable faunal diversity.

Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson

Bulletins - 3000 - 3999

Interest in the development of light lands in the south-eastern wheatbelt was spurred by the many ex-servicemen seeking farms after the 1939-45 World War.

Previous attempts to develop this area had been frustrated by poor crop yields, and by the poor carrying capacity of those volunteer pastures which developed on cleared land.

Research into reasons for the poor crop results was begun in 1948-49 with trials sown by Messrs Smith and Halpin between Borden and Lake Grace. The results clearly showed the important role played by copper and zinc in successful crop growth. Since then, field trials have been conducted …
