The sedimentary basins in SW Turkey (e.g., Kale-Tavas, Yatağan, and Ören basins) that developed after the closure of the Neotethys Ocean allow the reconstruction of the tectonic and paleogeographic history of the region. Due to the rich coal reserves, the Yatağan Basin provides a substantial amount of data to infer the paleoenvironment and paleoclimate during the middle Miocene to Pleistocene. Our work provides new paleontological and radiometric data to constrain the age, paleoclimate, and depositional environment of terrestrial deposits of this basin. We present fossil findings such as mammal bones, gastropods, and palynomorph assemblages from the base of the Turgut …
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.
Small Mammal Responses To Roadside Habitat Management In South Central Minnesota, Jeffrey W. Grimm, Richard H. Yahner
Small Mammal Responses To Roadside Habitat Management In South Central Minnesota, Jeffrey W. Grimm, Richard H. Yahner
Journal of the Minnesota Academy of Science
Responses of small mammals to management of roadsides in south central Minnesota were examined from August-October in 1980 and 1981. The Minnesota Department of Natural Resources established and maintained vegetation along portions of these roadsides by planting Bromus inermis and Medicago sativa as nesting cover for ring-necked pheasants (Phasianus colchicus) and with infrequent mowing. Landowners or state and county transportation departments maintained other roadside areas by frequent mowing of native vegetation. Mowing of roadsides had a negative effect on abundance of Blarina brevicauda, Peromyscus leucopus, Microtus pennsylvanicus, and Mustela erminea during both summer and autumn and on abundance of Peromyscus …
