Homing Studies Of Bank Swallows In Eastern Illinois, Jennifer Eileen Hagerstrom
Homing Studies Of Bank Swallows In Eastern Illinois, Jennifer Eileen Hagerstrom
Masters Theses
A series of homing experiments using 39 color-marked Bank Swallows (Riparia riparia) were carried out in eastern Illinois during the summer of 1975. The swallow colony was located four km east-northeast of Charleston, Illinois at the Charleston Stone Quarry. Eight release sites were located in the four compass directions from the home colony at distances of 14.4 to 32.3 km away.
The colony was approached before dawn and swallows were captured using tube traps. Birds were color-marked, banded, and taken in individual bags to the release site by automobile. Cloud cover, wind velocity, wind direction, and orientation behavior …

Scholarship and Professional Work - LAS
Spiroperidol, which blocks dopamine (DA) receptors, attenuated self-stimulation of the nucleus accumbens, septal area, hippocampus, anterior hypothalamus and ventral tegmental area. Dopamine is thus involved in self-stimulation of many sites (in addition to the lateral hypothalamus). The attenuation was not a simple motor impairment of the speed of bar-pressing in that the nucleus accumbens and septal self-stimulation rates were lower than those in treated animals self-stimulating at other sites (Experiment 1). Feeding was partly attenuated, and drinking was much less attenuated by the spiroperidol. Since the rats bar-pressed for brain- stimulation reward, chewed pellets to eat, and licked a tube …

The Ecology Of The Dominant Tick Species In The Northwestern Portion Of The Dismal Swamp National Wildlife Refuge, Mary Keith Garrett
The Ecology Of The Dominant Tick Species In The Northwestern Portion Of The Dismal Swamp National Wildlife Refuge, Mary Keith Garrett
Biological Sciences Theses & Dissertations
Elements of the ecology of the two dominant man-biting ticks were studied during 1971-1973 in two locations in Southeastern Virginia, namely, what is now the Dismal Swamp National Wildlife Refuge and Newport News City Park. Tick species composition, relative abundance, density, and distribution in the two areas were compared. In addition, the Dismal Swamp locality was used as a test area for studies on the survival of native, lab reared and translocated Dermacentor variabilis (Say) and Amblvomma americanum (L.) in relation to selected abiotic factors. The Newport News locality served as a control area for these studies.
The species …
Social Play And Play-Soliciting By Infant Canids, Marc Bekoff
Social Play And Play-Soliciting By Infant Canids, Marc Bekoff
Ethology Collection
The development of social interaction was studied in infant coyotes, beagles, and wolves. In this paper, social play behavior is discussed. Social play may be characterized in a number of ways: (i) actions from various contexts are incorporated into labile (unpredictable) temporal sequences; (ii) the "play bout" is typically preceded by a metacommunicative signal which indicates "what follows is play"; these signals are also observed during the bout; (iii) certain actions may be repeated and performed in an exaggerated manner; (iv) the activity appears "pleasurable" to the players.
By comparing these three species, some insight into the dynamics of social …
Defensive Behavior Of The Hognose Snake (Heterodon Platyrhinos), Brenda S. Hemken
Defensive Behavior Of The Hognose Snake (Heterodon Platyrhinos), Brenda S. Hemken
Masters Theses
Fourteen out of sixteen Heterodon platyrhinos eggs were hatched in late August, 1973. The immature snakes were manually stimulated and the resultant bluffing and death-feigning behaviors were observed. All of the experimental snakes bluffed, but only three out of ten feigned death. The major components of the bluffing behavior are spreading the neck, hissing, and striking. Death-feigning is preceded by contortions and shows variations in the positions of the mouth and tongue. The newly-hatched snakes exhibited both bluffing and death-feigning, indicating that the behaviors are innate.
An Introduction To The Ethology Of Citellus Variegatus, John W. Bell
An Introduction To The Ethology Of Citellus Variegatus, John W. Bell
Masters Theses
The above ground activity of the rock squirrel Citellus variegatus between November 6, 1972 and May 1, 1973, is described. This is a non-colonial species. Recognition was established between siblings by a nose to nose contact. In foraging they utilize almost any edible material available and during this time of year foraging is most intense between 11:00 a.m. and 4:00 p.m. Vocalization was limited to alarm calls, which brought the other squirrels to the top of the rocks to become alert, and squeals. Hibernation varied in length depending in part on the elevation and in some did not occur at …

Tool-Making And Tool-Using In The Northern Blue Jay, Thony B. Jones, Alan Kamil
Tool-Making And Tool-Using In The Northern Blue Jay, Thony B. Jones, Alan Kamil
Papers in Behavior in Biological Sciences
Laboratory-raised Northern blue jays (Cyanocitta cristata) have been observed tearing pieces from pages of newspaper and utilizing them as tools to rake in food pellets which were otherwise out of reach. The frequency of this behavior was dependent upon the motivational state of the jay and the presence of food pellets.
Lot Feeding Sheep In Sheds, H E. Fels, B. Malcolm
Lot Feeding Sheep In Sheds, H E. Fels, B. Malcolm
Journal of the Department of Agriculture, Western Australia, Series 4
The need to gather and hold sheep for slaughter or live shipment led a West Australian company!, with the Department of Agriculture, to investigate the use of sheds for short term lot feeding of sheep. Preliminary examination suggested that feedlot sheds connected by a sheep footpath to the abattoirs, railway or saleyards could be cheaper as well as more practicable than continued use of holding paddocks.
The first week or two are commonly the most difficult in lot feeding sheep or cattle. Long-term indoor lot-feeding is a normal practice in some overseas countries but we did not know whether untrained …
The Development Of Social Interaction, Play, And Metacommunication In Mammals: An Ethological Perspective, Marc Bekoff
The Development Of Social Interaction, Play, And Metacommunication In Mammals: An Ethological Perspective, Marc Bekoff
Ethology Collection
Analysis of the dynamics of the ontogeny of social interaction is of critical importance in order that behavioral development may be comprehended in its own right, and the relationship between infant and adult behavior understood. In this review, general concepts of behavioral development in mammals are discussed and analyzed, and the many variables that are involved are considered. When it is impossible to control or observe the social interaction of the developing organism in its natural environment, captive subjects should be used. There is increasing evidence that results obtained with the latter are related to social organization observed in the …
Three-Configuration Matching-To-Sample In The Pigeon, Alan Kamil, Robert A. Sacks
Three-Configuration Matching-To-Sample In The Pigeon, Alan Kamil, Robert A. Sacks
Papers in Behavior in Biological Sciences
Pigeons were trained on a zero-delay matching-to-sample procedure during which only three of the four possible stimulus configurations were presented. Subsequently, all birds were exposed to all four configurations as a transfer test. A high degree of negative transfer from the three training configurations was obtained in Experiment 1. The results of Experiment 2 indicated that three-configuration training produced differential position-preference effects. During the transfer test, responding after one sample stimulus was apparently based on position, while responding after the other sample was based on color.
Anatomical And Behavioral Aspects Of Killing And Feeding By The Least Weasel, Mustela Nivalis L., Gary A. Heidt
Anatomical And Behavioral Aspects Of Killing And Feeding By The Least Weasel, Mustela Nivalis L., Gary A. Heidt
Journal of the Arkansas Academy of Science
The least weasel (Mustela nivalis) is a remarkably well adapted predator of mice and other small animals. Each kill is rather stereotyped, in that the weasel grabs the prey by the nape of the neck and bites through the base of the skull and/or throat, using its lithe body to "wrap up" and hold the prey. The least weasel will kill mice successively until it is too exhausted physically to kill more. Mice are always eaten from the head posteriorly until completely consumed.
Grooming Behavior And Competitive Dominance In The Albino Rat, Irwin M. Spigel, Susan Trivett, David Fraser
Grooming Behavior And Competitive Dominance In The Albino Rat, Irwin M. Spigel, Susan Trivett, David Fraser
Social Behavior Collection
An experiment sought to compare dominance manifested in water competition under two levels of deprivation, with grooming activity in a non-deprived state. While competitive dominance was significantly related to motivational level, grooming emerged as a more stable indicator of social ascendance, and did not require prior manipulation of a biological state. The implications of this observation for broader aspects of social motivation arc discussed.
Annual Pasture And Weed Plant Ecology, B J. Quinlivan

Journal of the Department of Agriculture, Western Australia, Series 4
The purpose of this article is to outline a few basic principles of pasture and weed ecology with particular reference to seed dormancy mechanisms.
These principles apply to many pasture plants and weeds, although their relative importance varies with the particular plants under study.
Effect On Bees Of Insecticides Used On Rape, A C. Kessell
Effect On Bees Of Insecticides Used On Rape, A C. Kessell
Journal of the Department of Agriculture, Western Australia, Series 4
Rapeseed could provide beekeepers in Western Australia with a valuable new honey crop—hut insecticidal spraying of rape at flowering time is a potentially serious threat to most commercial beekeepers.
There are indications that insect pollination may improve rapeseed yields, so both growers and beekeepers could gain from a co-operative approach to the problem. Spraying after sundown and preventing spray drift to nearby apiaries should avoid most losses.
A Taxonomic Study Of Two Nominal Subspecies Of Pikas (Ochotona Princeps) In The Cascade Mountains Of Oregon, Richard M. Coots
A Taxonomic Study Of Two Nominal Subspecies Of Pikas (Ochotona Princeps) In The Cascade Mountains Of Oregon, Richard M. Coots
Dissertations and Theses
Pikas from four colonies in the Cascade Mountains of Oregon were examined. Two colonies were chosen from within the geographical distribution of two nominal subspecies. A discriminate analysis of morphological measurements taken from the specimens showed that each colony could be distinguished from each other. Each colony studied showed more intra-colony similarity than inter-colony similarity regardless of distance separating the colonies or subspecies designations. The results indicate that the validity of subspecies designations for this species can be questioned.

Operant Conditioning In The Garter Snake (Thamnophis), William A. Schmitz
Masters Theses
Ten garter snakes were tested for runway acquisition, correct turn response in a simple T-maze, or both, for food reinforcement. Seven of seven subjects met criterion for learning to run a 23 inch long alleyway. Mean latency times showed a general decrease over a 23 day period. Five of nine subjects met criterion for learning a correct turn response in a simple T-maze. Subjects mastering the task required from 14-157 trials. One of two subjects met criterion for learning the reverse response of the T-maze exercise, requiring 35 trials. Results are similar to those previously reported for reptiles and other …
A Comparison Of Nocturnal Restlessness Of Caged Thrushes And Migration Of Free Thrushes, Charles Goodwin Kjos
A Comparison Of Nocturnal Restlessness Of Caged Thrushes And Migration Of Free Thrushes, Charles Goodwin Kjos
Masters Theses
Nocturnal activity (Zugunruhe) of eight caged, radio-tagged thrushes (Hylocichla spp.) was compared by signal analysis with the occurrence of migration in 16 free, radio-tagged thrushes over a 37-night period during the autumn of 1970 in central Illinois. The study was conducted to determine the extent of synchrony of Zugunruhe and migration in these nocturnal migrants in fall. Zugunruhe frequently occurred on nights when there was no migration, but migration occurred only on nights when at least 50 per cent of the caged birds were active. Except for one departure which was atypical in several respects, migration occurred …
An Investigation Of The Behavior Of Citellus Townsendii Townsendii (Bachman) In Central Washington, Mark Roy Fuller
An Investigation Of The Behavior Of Citellus Townsendii Townsendii (Bachman) In Central Washington, Mark Roy Fuller
All Master's Theses
This study of the behavior of Citellus townsendii townsendii was based on field observations of animals at their northern most distribution. The squirrels' seasonal activity and behavioral repertoire, when considered with environmental parameters, suggest important adaptations for survival. The animals were in torpor from about July to February. Activity generally occurred during the midmorning hours, allowing them to avoid temperature extremes. Quantitative analysis of behavioral observations indicated that most activities occurred in a non-random order.

Sub-Aversive Response Contingent Foot Shock As A Positive Reinforcer, Robert Lea Fulwiler
All Master's Theses
Forty-eight rats were divided into 8 groups; four were maintained under normal conditions and the other four under sensory deprivation and tested at o, 3, 6, and 9 days after condition institution. The response was placing the head through a hole in the operant chamber and the stimulus (0, 1.2, 4, or 12 Vac) was contingent upon the response. Analysis ot variance disclosed significant differences (p<.01) between the deprived and the non-deprived groups at days 6 and 9; and a significant interaction between deprivation condition and time of test. No differences were shown between the stimulus intensities indicating that the stimulus did not have a reinforcing effect.

Linseed Within The Clover Ley Farming System, Department Of Agriculture, Western Australia
Linseed Within The Clover Ley Farming System, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
LINSEED was one of the first crops to be widely used as an alternative to cereals in the over-17 inch rainfall areas. It is now an established crop with a total 1969 production worth just under half a million dollars.
Linseed is currently worth nearly twice as much as wheat per bushel, wih its short term prospects still attractive.

Grain Aeration On The Farm, G D. Rimes
Journal of the Department of Agriculture, Western Australia, Series 4
ALTHOUGH grain aeration is a well known and widespread technique employed to prevent insect development in stored grain, the installations are invariably designed for large scale grain handling authorities.
Experimental work carried out in Western Australia over the last four storage seasons has shown that simple unsophisticated equipment can be of direct use in farm storage.

Subalpine Cover Ecology Of Eutamias Amoenus, Eutamias Townsendii And Other Small Mammals In Huckleberry Park, Mount Rainier National Park, Don H. Meredith
All Master's Theses
Little work has been done on the ecology of alpine and subalpine small mammals. They are included in faunal surveys, but little is known of their habits. In the summer of 1969 this study was undertaken in subalpine Huckleberry Park, Mount Rainier National Park, to determine the species of small mammals in the area and some of their relationships with the environment and each other. The relationships between E. amoenus and E. townsendii were of special interest.

Nitrogen Fertiliser Survey, Department Of Agriculture, Western Australia
Nitrogen Fertiliser Survey, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
THE DECEMBER, 1968 issue of the "Journal of Agriculture" included, as part of an article on the economics of nitrogen fertiliser use, a lift-out section for farmers to complete and return to the Journal.
In the lift-out, farmers were asked to calculate their fertiliser costs and answer a series of questions about the use of nitrogen on their farms.
