Bats Of Kansas, Dale W. Sparks, Curtis J. Schmidt, Jerry R. Choate Jan 2011

Bats Of Kansas, Dale W. Sparks, Curtis J. Schmidt, Jerry R. Choate

Sternberg Museum of Natural History Faculty Publications

In memory of Curtis J. Schmidt (1977-2022)

Invariably, our most feared neighbors on planet earth are the animals that we know the least about. Almost as frequently, when people are exposed to these animals, the fear turns quickly to fascination. Unfortunately, many of these animals are accessible only to the professional scientist. Though science has made great strides in understanding the basic biology and behaviors of many of our least-known animals, this information is generally kept locked away from the general public by the dry, technical language of science. In this publication, it is our hope to open your eyes …

Turkish Journal of Zoology

In order to study population structure in the codling moth (Cydia pomonella L.) using RAPD markers, 13 geographical populations from northwestern Iran were collected during 2003 and 2004. Genomic DNA was extracted from 10 overwintering larvae of each population. Out of 60 tested primers, 18 amplified 236 polymorphic bands. The total number of bands in the population varied from 169 to 206 in the Mughan and Zunuz populations, respectively. Within-population genetic diversity, based on Nei's genetic index, ranged from 0.228 to 0.281 for the Shabestar and Zunuz populations, respectively. An analysis of the molecular variance revealed significant differences within and …

Occurrence Of Blarina Brevicauda In Arkansas And Notes On The Distribution Of Blarina Carolinensis And Cryptotis Parva, R. S. Pfau, D. Blake Sasse, M. B. Connior, I. F. Guenther

Journal of the Arkansas Academy of Science

We provide an update on the species and distribution of shrews occurring in Arkansas. Shrews were collected within Arkansas Game and Fish Commission Wildlife Management Areas and along the Buffalo National River. We also searched mammal collections at several institutional museums to provide additional locality records for Cryptotis parva. Specimens of Blarina were identified to species by DNA sequencing of the mitochondrial cytochrome b gene. Previously, Blarina hylophaga was believed to occur in the northwest corner of Arkansas and B. carolinensis throughout the rest of the state. However, our genetic analysis revealed that it is B. brevicauda that occupies the …

Seasonal Activity, Population Characteristics, And Age Estimation In The Aquatic Salamander, Siren Intermedia Nettingi (Goin), J. A. Sawyer, S. E. Trauth

Journal of the Arkansas Academy of Science

We conducted a study of the Western Lesser Siren (Siren intermedia nettinigi), at a locality termed the Airport Road site in Jonesboro (Craighead County, AR) from November 2004 until March 2007. This site consisted of a network of roadside ditches in cultivated lawns in an industrial park. Even though sirens are known to occur frequently in ditches, most studies of the genus Siren have taken place in natural wetlands. We compiled mark-recapture data at the Airport Road site for each season to determine if the seasonal activity pattern for sirens in northeast Arkansas varied from activity data previously published from …

Summary Of Previous And New Records Of The Arkansas Darter (Etheostoma Cragini) In Arkansas, B. K. Wagner, M. D. Kottmyer, M. E. Slay

Journal of the Arkansas Academy of Science

The Arkansas Darter, Etheostoma cragini, has an extremely limited distribution in Arkansas and is designated as a candidate for listing under the federal Endangered Species Act. It was first documented in the state in 1979 in Wilson Spring near Fayetteville. Between 1979 and 1985 it was collected in 4 additional headwater streams in Benton and Washington counties. A 1997 study documented the persistence of the species in 3 of the 5 historic streams, but 1 stream yielded only a single individual. A 2004-2005 study reassessed the status of the 5 historically known populations and searched broadly for new populations, documenting …

The External Morphology Of The Gill Of Patella Caerulea L. (Mollusca: Gastropoda), Deni̇z Akşi̇t, Beri̇a Falakali Mutaf

Turkish Journal of Zoology

Gross morphology of the gill was studied using a scanning electron microscope (SEM) in order to associate it with its function in genus Patella. Secondary gills consisted of a single layer of gill folds, which appear mostly as triangular leaflets in scanning electron micrographs. The lamellae showed a prominent thickening on the free margin and horizontal swellings, which bear a series of ciliary structures on the frontal surface, as well as disperse bunches. They differed from the discocilia and, because chemoreception has been attributed to them in the absence of an osphradium, they are thought to contribute to the primary …
