Investigation Of Fluorescence In Selected Mammals Of Arkansas, C. Renn Tumlison, Terry L. Tumlison
Investigation Of Fluorescence In Selected Mammals Of Arkansas, C. Renn Tumlison, Terry L. Tumlison
Journal of the Arkansas Academy of Science
The adaptive value of fluorescence among the vertebrates has been studied most in fishes and birds, and only a few observations have been published regarding fluorescence in the pelage of mammals. Recently, reports of fluorescence in some marsupials, the platypus, and in flying squirrels have become available. We report the occurrence of fluorescent properties in some mammals from Arkansas. Most carnivores, bats, and rodents did not exhibit the property when viewed under UV light. However, opossums, rabbits, a weasel, muskrats, and moles showed substantial UV response, and a few other mammals showed minor fluorescence. Colors fluoresced included pink, green, and …
Animal Mourning: Précis Of How Animals Grieve (King 2013), Barbara J. King
Animal Mourning: Précis Of How Animals Grieve (King 2013), Barbara J. King
Animal Sentience
Abstract: When an animal dies, that individual’s mate, relatives, or friends may express grief. Changes in the survivor’s patterns of social behavior, eating, sleeping, and/or of expression of affect are the key criteria for defining grief. Based on this understanding of grief, it is not only big-brained mammals like elephants, apes, and cetaceans who can be said to mourn, but also a wide variety of other animals, including domestic companions like cats, dogs, and rabbits; horses and farm animals; and some birds. With keen attention placed on seeking where grief is found to occur and where it is absent …
Mammal Capture Success Of Scent Stations And Remote Cameras In Prairie And Forest Habitat, Marc N. Mckinney, Aaron M. Haines
Mammal Capture Success Of Scent Stations And Remote Cameras In Prairie And Forest Habitat, Marc N. Mckinney, Aaron M. Haines
Journal of the Iowa Academy of Science: JIAS
Two common noninvasive (i.e., no stress to the animal) methods used to survey mammals include track stations (i.e., track captures of mammals) and remote camera-traps (i.e., photo-captures of mammals). Our objectives were to compare capture effectiveness of both track stations and remote cameras in both forested and prairie habitats. This project was conducted on 4 study sires (2 forested sires and 2 prairie sites) located in Fayette County, Iowa. Each study site had 6 trapping stations 2:: 100 m apart. We monitored traps for a total of 216 trap nights and we recorded a total of 368 captures composed of …
Mammals Of Iowa: Holocene To The End Of The 20th Century, John B. Bowles, Daryl L. Howell, Richard P. Lampe, Howard P. Whidden
Mammals Of Iowa: Holocene To The End Of The 20th Century, John B. Bowles, Daryl L. Howell, Richard P. Lampe, Howard P. Whidden
Journal of the Iowa Academy of Science: JIAS
This review of Iowa's mammal fauna at the close of the 20th century summarizes changes in distributional patterns following Euroamerican settlement in the early 1800s. Data from historical records, museum specimens, and presettlement late Holocene fossils indicate presence of 69 resident mammals at that time. Hunting pressures and the conversion of prairie and forest to agricultural fields reduced the populations and ranges of many state mammals, and 14 species were extirpated by 1900. An additional 15 species are either uncommon or rare today, and the Iowa Department of Natural Resources lists four species as endangered, three as threatened and one …
Current Status Of The Plains Pocket Mouse, Perognathus Flavescens, In Iowa, Gregory M. Wilson, John B. Bowles, Justin W. Van Zee
Current Status Of The Plains Pocket Mouse, Perognathus Flavescens, In Iowa, Gregory M. Wilson, John B. Bowles, Justin W. Van Zee
Journal of the Iowa Academy of Science: JIAS
Published and unpublished accounts of the plains pocket mouse (Perognathus flavescens) were utilized to document the existence of extant populations and to summarize and report additional data about the biology of this state endangered Iowa species. Populations of P. flavescens exist in western (Harrison, Monona, and Plymouth counties) and extreme eastern (adjacent portions of Louisa and Muscatine counties) Iowa, the latter of which represents the eastern-most record for the species in North America. In addition, we document a new locality for P. flavescens from the interior of the state (Benton County). All known populations of P. flavescens in Iowa occur …
History Of Mammal Study In Iowa, John B. Bowles
History Of Mammal Study In Iowa, John B. Bowles
Journal of the Iowa Academy of Science: JIAS
The first records of mammals in Iowa were from explorers, survey parties heading westward and early seeders. Generation of checklists of state mammals began in 1840 and culminated with the annotated list by Scott (1937) and biogeographic analysis by Bowles (1975). Recent focus has been on rare species status and mammalian ecology, e.g., Loess Hills, riparian habitat, agricultural practices, and reestablished grasslands.
