Habitat Of Red-Backed Vole, Harvey L. Gunderson
Habitat Of Red-Backed Vole, Harvey L. Gunderson
University of Nebraska State Museum: Mammalogy Papers
These data are a part of a study of small mammal populations at Cedar Creek Forest, Anoka County, Minnesota. The live-trapping area of 5.0 acres, with 81 traps spaced 52 feet apart, was in a tamarack-white cedar bog. The study extended over a period of 7 years (1949-1955). Trapping periods of five days (four nights) extended from early May to the first part of October. In all, there were 14,580 trap-nights. A total of 428 voles were marked and weighed; data on 25 dead unmarked individuals are also included.
A frequency index was calculated for each station. This index was …

Embryological Development Of Cucumaria Curata, Edmund Hobart Smith
Embryological Development Of Cucumaria Curata, Edmund Hobart Smith
University of the Pacific Theses and Dissertations
Almost no work has been done on the brooding habits of Cucumaria curata Cowles 1902 from the Pacific Coast of North America. Most of the embryological investigations of holothurians on this coast have been with species having free swimming larval forms (Johnson and Johnson, 1950). Since the majority Holothurians have planktonic larvae, a study of the direct development found in C. curate might prove beneficial in comparing the ecological distribution of this species with those having planktonic larvae. The brooding type of development is found in polar species, but seldom found in warmer waters. This may have some direct effect …

Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
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. …
Taxonomic Studies On Adult And Larval Ascidians From California, Robert Christian Haugsten
Taxonomic Studies On Adult And Larval Ascidians From California, Robert Christian Haugsten
University of the Pacific Theses and Dissertations
The primary purpose of this research is to further morphological studies on larval ascidians and to encourage greater reliance on larval structures in ascidian taxonomy. This may necessitate some revisions in current classifications, but it is hoped that such revisions will lead to a better understanding of the group. Some general considerations of ascidians are here included for the benefit of those who may not be familiar with them. All specimens used in this study were collected at the Pacific Marine Station area at Dillon Beach, California, during June, July, and August of 1957.

Observations On The White-Faced Ibis, Plegadis Chihi, In Louisiana, Horace William Belknap
Observations On The White-Faced Ibis, Plegadis Chihi, In Louisiana, Horace William Belknap
LSU Historical Dissertations and Theses
The eight-month study deals with the White-faced Ibis, Plegadis chihi, in southwestern Louisiana. It affirms the absence of the closely related Glossy Ibis, Plegadis falcinellus, as a breeding bird in that area today. Data on feeding habits, social behavior, nesting cycles, and plumage changes in chihi are presented as a step toward clarifying the relationship of these two puzzling forms of ibis; but the full significance of these findings cannot be ascertained until more is known about the habits of falcinellus. The most important conclusions concern plumage changes. It is shown that published descriptions of plumage and molt in chihl …

Case Of Collecting Tick Amblyomma Lepidum Dönitz, 1909, In Azerbaijan, M. V. Pospelova-Shtrom, N. S. Abusalimov
United States Naval Medical Research Unit 3: Publications
First paragraph:
On 18 May 1954, (a specimen of) Burhinus oedicnemus (L.) was killed in the Lenkoransky region of Azerbaijan S.S.R.; on its head a male Amblyomma lepidum Dönitz, 1909, was found. Morphological characters of this tick, size and shape of body, characteristic light and dark ornamentation of dorsal shield, punctation, shape, and two colors of festoons, size and shape of cervical and lateral grooves, hypostome, peritreme, projection on coxae, and spherical orbited eyes correspond to those in the description of A. lepidum, given in Robinson monograph. Only on four anterior festoons a small light spot is found (in …
