Effect Of Double Interspiking On Fertility, Behavior, And Blood Parameters In Broiler Breeder Males Reared Under Heat Stress Conditions, Karianne Mei-Ying Chung
Effect Of Double Interspiking On Fertility, Behavior, And Blood Parameters In Broiler Breeder Males Reared Under Heat Stress Conditions, Karianne Mei-Ying Chung
Masters Theses
Broiler breeders experience a natural decline in fertility levels as a flock ages. A male management practice such as double interspiking could be applied to counteract this decline. Our objective was to investigate the effects of double interspiking on flock fertility, testosterone concentrations, stress responses, and behavioral responses of broiler breeders in heat stressed environments. Two hundred and eighty-eight broiler breeder pullets and thirty-six broiler breeder roosters (Ross 708) were assigned to three groups at 21 weeks of age (WOA). All three groups were housed in slatted floor pens in which room temperature cycled from 23.8 to 30 C to …
Identifying And Understanding The Spatial Distribution Of Bobcat And Coyote Behavior, Ryan Radford Wilson
Identifying And Understanding The Spatial Distribution Of Bobcat And Coyote Behavior, Ryan Radford Wilson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A common observation in animal space use studies is that animals do not use space uniformly, but rather use some areas of their home ranges and territories with much higher intensity than others. Numerous methods have been developed to estimate these "core areas"; however, all of the current methods available are based on arbitrary rules. Additionally, most studies do not attempt to understand what behavioral processes lead to the observed patterns of non-uniform space use. This study has four main objectives: 1) to develop an objective and more precise method for estimating core areas, 2) to understand the processes leading …
Does The Manipulation Of Tail Position Facilitate Extinction Of Canine Phobic Behavior?, Rebecca A. Zarate
Does The Manipulation Of Tail Position Facilitate Extinction Of Canine Phobic Behavior?, Rebecca A. Zarate
Theses and Dissertations - UTB/UTPA
The phobic behavior of interest is tail tucking which is indicative of submission. In this study the tail was physically manipulated by the use of a custom made harness to hold the tail up in a dominant position to ideally extinguish phobic behavior through reciprocal inhibition. The harness did not hold the tail up the entire duration of the interventions, although it still held the base of the tail up. The intervention did not appear to have an affect on the two of the five subjects. The three more phobic canines did display some behavioral changes, although the changes noticed …

A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur
Scholarship and Professional Work - LAS
We used four surveys to collect information about the birth, physical growth, and behavioral development of 12 African elephant calves born in captivity. The management of the birth process and neonatal care involved a variety of standard procedures. All of the calves were born at night, between 7PM and 7AM. The calves showed a systematic progression in behavioral and physical development, attaining developmental milestones at least a quickly as calves in situ. This study emphasized birth-related events, changes in the ways that calves used their trunks, first instances of behaviors, and interactions of the calves with other, usually adult, elephants. …

John James Audubon, a well-known bird expert and nature enthusiast, described wild turkeys as birds of great beauty. The history and origin of wild turkeys is uncertain, yet many share Audubon’s sentiment that the wild turkey is “one of the most interesting of the birds indigenous to the United States of America.” Today, wild turkeys can be found throughout the nation. Following the selection of the bald eagle as the American symbol, Benjamin Franklin remarked that the turkey was more “respectable”, and a “true original native”.

Although a number of fish species have been studied in their freshwater life stages, further research on the behavior and habitat requirements of ocean-going fish is required. While fishes have historically been regarded as more “primitive” than other vertebrate groups, Rodriguez et al concluded that several memory and learning systems of bony fishes are noticeably similar to those of reptiles, birds, and mammals. When animals as small and under appreciated as fish display complex mating systems, parental care, and demonstrate the ability to traverse significant distances using olfactory and celestial cues, it is clear that previously established definitions of intelligence …
Prolonged Intensive Dominance Behavior Between Gray Wolves, Canis Lupus, L. David Mech, H. Dean Cluff
Prolonged Intensive Dominance Behavior Between Gray Wolves, Canis Lupus, L. David Mech, H. Dean Cluff
USGS Northern Prairie Wildlife Research Center
Dominance is one of the most pervasive and important behaviors among wolves in a pack, yet its significance in free-ranging packs has been little studied. Insights into a behavior can often be gained by examining unusual examples of it. In the High Arctic near Eureka, Nunavut, Canada, we videotaped and described an unusually prolonged and intensive behavioral bout between an adult male Gray Wolf (Canis lupus) and a male member of his pack, thought to be a maturing son.With tail raised, the adult approached a male pack mate about 50 m from us and pinned and straddled this …
Behavior Comparisons Of Two Rearing Protocols For Whooping Cranes Raised By Costumed Caregivers And Trained For An Ultralight-Led Migration, Glenn H. Olsen, John B. French
Behavior Comparisons Of Two Rearing Protocols For Whooping Cranes Raised By Costumed Caregivers And Trained For An Ultralight-Led Migration, Glenn H. Olsen, John B. French
Proceedings of the North American Crane Workshop
Whooping crane (Grus americana) colts are raised at USGS Patuxent Wildlife Research Center, Laurel, Maryland for the first 40-60 days of a chick's life as part of the Whooping Crane Eastern Partnership (WCEP) ultralight-led reintroduction. Numbers raised for WCEP are increasing each year. Up to 2005, we raised whooping crane chicks in the Propagation Building where there are 10 indoor/outdoor pens, 8 full pens, and 2 half-size pens. In 2005 WCEP proposed increasing the number of colts reared to 20-24, numbers beyond the capacity of the facility. To accommodate this greater number of chicks, we modified several outdoor …
The Use Of High Frequency Gps Data To Classify Main Behavioural Categories In A Przewalski’S Horse In The Mongolian Gobi, Petra Kaczensky, Klaus Huber
The Use Of High Frequency Gps Data To Classify Main Behavioural Categories In A Przewalski’S Horse In The Mongolian Gobi, Petra Kaczensky, Klaus Huber
Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
Behavioral observations of free ranging animals can provide important insight into many aspects of their biology but are not without problems. The recent development of GPS technology allows to remotely collect high precision location data at fixed intervals. We tested whether it is possible to classify the behavior of a Przewalski’s horse in the Mongolian Gobi into Resting, Grazing and Moving based on GPS locations collected at 15 minute intervals by comparing GPS data with direct observations. Although behavioral categories lasting for 15 minutes could by fairly reliably separated based on the distances covered between successive fixes, almost half the …
Growth And Age At Reproductive Maturity Of The Carolina Pigmy Rattlesnake, Sistrurus M. Miliarius (Reptilia: Serpentes), Kevin Robert Messenger
Growth And Age At Reproductive Maturity Of The Carolina Pigmy Rattlesnake, Sistrurus M. Miliarius (Reptilia: Serpentes), Kevin Robert Messenger
Theses, Dissertations and Capstones
Growth and age at reproductive maturity are life history attributes that play an important role in the development of proper management strategies. The Carolina Pigmy Rattlesnake, Sistrurus m. miliarius, is one of two dwarf rattlesnake species. The subspecies ranges from eastern NC to nearly the southern tip of SC and into the northeastern portion of GA. In NC, where the species’ status is of Special Concern, fragmentation and land development have destroyed most of its historic range. Its small size also makes it highly susceptible to predation. In some parts of the range, commercial collection is another pressure the species …
Observational Learning In Wild And Captive Dolphins, Deirdre Yeater, Stan A. Kuczaj Ii
Observational Learning In Wild And Captive Dolphins, Deirdre Yeater, Stan A. Kuczaj Ii
Psychology Faculty Publications
Many non-human species imitate the behavior of others, and dolphins seem particularly adept at this form of observational learning. Evidence for observational learning in wild dolphins is rare, given the difficulty of observing individual wild animals in sufficient detail to eliminate other possible explanations of purported imitation. Consequently, much of the evidence supporting observational learning in dolphins has involved animals in captive settings. This research suggests that dolphins have an affinity for mimicry, and that they are more successful at observational learning if they choose to imitate another rather than being asked to do so. These results, combined with those …

The chicken is the world’s most numerous domesticated bird, with over 52 billion farmed worldwide in 2008, rivaling the dog as the most ubiquitous domestic animal globally. These birds have fascinated scholars and researchers since the dawn of Western civilization, and recent studies are beginning to reveal the depths of their complexity and cognitive ability. According to Andrew F. Fraser, professor of veterinary surgery at Memorial University of Newfoundland, and Donald M. Broom, professor of animal welfare at University of Cambridge: “Those who have studied the behaviour of the domestic fowl in detail…, especially those who have looked at feral …
Behavior And Habitat Use Of Greater Sandhill Cranes Wintering In East Tennessee, David A. Aborn
Behavior And Habitat Use Of Greater Sandhill Cranes Wintering In East Tennessee, David A. Aborn
Proceedings of the North American Crane Workshop
An increase of eastern greater sandhill cranes (Grus canadensis tabida) stopping over and wintering at the Hiwassee Wildlife Refuge in east Tennessee has led to overcrowding at the refuge, resulting in crane use of private property. Proper management is needed to prevent the cranes from becoming a nuisance, increase the suitability of the refuge for waterfowl, and reduce the likelihood of a disease outbreak. Observations of cranes revealed that cranes spent 83% of their time foraging, alert, or preening. Sandhill cranes foraged primarily in agricultural and grassy fields, whereas mudflats and shallow water were used for preening and …
The Interictal State In Epilepsy And Behavior, Daniel Tice Barkmeier
The Interictal State In Epilepsy And Behavior, Daniel Tice Barkmeier
Wayne State University Dissertations
Epilepsy is one of the most common neurological diseases, affecting up to 1% of the world population. Epilepsy remains poorly understood and there are currently no medications to cure it. Patients with epilepsy have both seizures as well as another type of abnormal activity between seizures, known as interictal spikes. Interictal spikes have thus far been poorly researched, yet growing evidence supports an important role for them in epilepsy. In this project, we first show the high variability between reviewers in marking interictal spikes on intracranial EEG, and then develop and test an automated detection method to solve this problem. …

Female Humpback Whale (Megaptera Novaeangliae) Reproductive Class And Male-Female Interactions During The Breeding Season, Meagan E. Jones
Antioch University Full-Text Dissertations & Theses
This study examined whether female reproductive class (i.e., presence or absence of a calf) in humpback whales (Megaptera novaeangliae) affects female behavior and male-female interactions on the Hawaiian breeding grounds. From 2003-2008, 295 female-calf groups (with or without a male escort) and 256 female no-calf groups (with a male) were observed. Forty-one female no-calf groups were confirmed male-female pairs by genetic sexing or photo-identification. Focal follows of 36 male-female pairs and 50 female-calf groups (29 escorted and 21 unescorted female-calf groups) were analyzed for time budget and movement estimates. Relative fluke size (fluke photogrammetry, n=30) and sighting histories …
