Download or read book Behavioral and Disease Ecology of Gopher Tortoises Gopherus Polyphemus Post Exclusion and Relocation with a Novel Approach to Homing Determination written by Johnathan Oliver Howard Napier and published by . This book was released on 2018 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: I also found that G. polyphemus engages in homing behavior, but only in males. Behavioral differences were also found between the sexes with respect to burrowing behavior. Overall health, disease prevalence, and immune response were unaffected by relocation and exclusion, nor were they statistically correlated. Signs were unreliable as etiological agents, outperformed by serological detection. I determined that the Sabal Trail pipeline as a potential stressor did not affect movement behavior, homing, nor the disease/immune profile of G. polyphemus in this study.

This book was released on 2015 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gopherus polyphemus, commonly known as a gopher tortoise, is a keystone species found in the southeastern United States that uses homing behaviors to locate their burrow after traveling. These behaviors are influenced by multiple systems- visual landmarks, olfaction, and magnetic sense of direction but the extent of the influence has never been established. This experiment was an attempt to gauge the extent that each had in influencing the homing ability of the tortoises by temporarily blocking these senses before moving the tortoise approximately 46 m away from the burrow it was found in or closest to and timing how long it took for the tortoise to locate a burrow. The results of the experiment support the idea that visual landmarks have the greatest influence closely followed by olfaction since the vision deprivation trials were the longest, irritated the tortoises most, and the tortoises starting blatantly using olfaction to get their bearings.

Book excerpt: Provides an overview of extant desert tortoise literature, summarizing literature on taxonomy, morphology, genetics, and paleontology and paleoecology of the desert tortoise, as well as its general ecology. Literature on desert tortoise ecology encompasses distribution and habitat, burrows and dens, reproduction, growth, physiology, feeding and nutrition, mortality factors, and behavior. Information on habitat deterioration, management of tortoises, their legal status and tortoise husbandry is also included. The manuscript is a complete overview of existing literature, including peer-reviewed literature and other literature. Information was compiled from materials available in 1991.

This book was released on 2021 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: Gopher tortoises (Gopherus polyphemus) are a threatened, keystone species that play important roles in upland habitats throughout the southeastern United States. Climate change could have diverse and strong effects on the fecundity and population demographics of gopher tortoises, as they are long-lived reptiles that rely on environmental temperatures for thermoregulation and sex determination. I used a population of translocated gopher tortoises at Nokuse Plantation, located in the panhandle of Florida, as a common garden experiment to assess whether plasticity of several nesting behaviors (i.e., nest temperature, depth, and orientation) and components of fecundity (i.e., clutch size, egg size, hatching success) might compensate for changes in environmental conditions. I compared nest characteristics among translocated females (from across the state of Florida) and examined how multiple measures of environmental distance, such as difference in warm season temperature between the translocation and origin sites, impacted aspects of fecundity. I found that tortoises did not exhibit plasticity and did not adjust their nesting behaviors in response to novel conditions. Tortoises that originated from climates that were more dissimilar from that of the translocation site placed their nests at different locations within the burrow apron, under differing amounts of canopy cover, and at different depths. Environmental distance of translocation also impacted hatching success, although there was no direct impact of nest site selection on hatching success, suggesting that differences in hatching success due to female origin are more a consequence of physiology (e.g., developmental processes) than female behavior. Although there was a high degree of variability in the direction of the effect of environmental distance – i.e., whether tortoises from more or less similar climates had greater hatching success – these results may indicate a strong degree of local adaptation that is still apparent even several years after translocation. These findings suggest that gopher tortoises may not be resilient to impending environmental changes, and behavior plasticity should not be expected. Effects on nest site selection, incubation temperatures, and hatching success suggest that translocation guidelines should consider climate differences when selecting relocation sites.
Download or read book Animal Homing written by F. Papi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homing phenomena must be considered an important aspect of animal behaviour on account of their frequent occurrence, their survival value, and the variety of the mechanisms involved. Many species regularly rely on their ability to home or reach other familiar sites, but how they manage to do this is often uncertain. In many cases the goal is attained in the absence of any sensory contact, by mechanisms of indirect orientation whose complexity and sophistication have for a long time challenged the skill and patience of many researchers. A series of problems of increasing difficulty have to be overcome; researchers have to discover the nature of orienting cues, the sensory windows involved, the role of inherited and acquired information, and, eventually, how the central mechanisms process information and control motory responses. Naturally, this book emphasizes targets achieved rather than areas unexplored and mysteries unsolved. Even so, the reader will quickly realize that our knowledge of phenomena and mechanisms has progressed to different degrees in different animal groups, ranging from the mere description of homing behaviour to a satisfactory insight into some underlying mechanisms. In the last few dacades there have been promising developments in the study of animal homing, since new approaches have been tried out, and new species and groups have been investigated. Despite this, homing phenomena have not recently been the object of exhaustive reviews and there is a tendency for them to be neglected in general treatises on animal behaviour.

Download or read book Polarized Light in Animal Vision written by Gábor Horváth and published by Springer Science & Business Media. This book was released on 2004-01-12 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the human eye can practically cope only with two aspects of light, brightness and colour, many animals use polarization as a further source of visual information. The text starts with an introduction into imaging polarimetry, an efficient technique for measuring light polarization, and moves onto a description of the various polarization patterns occurring in nature, such as celestial polarization. The major part of the book is dedicated to the fascinating question: How do animals use polarization patterns? Following a compendium of the physiology of polarization sensitivity, several case studies are presented, such as honeybees or ants using polarized light as a compass or aquatic animals orientating by the underwater polarization. Further, it is explained how man-made objects affecting the natural optical environment may disorientate animals. For instance, as in the case where oil or glass surfaces can be more attractive for water-seeking polarotactic insects than the water surface.
