A Comparison Of Prairie Vole Audible And Ultrasonic Pup Calls And Attraction To Them By Adults Of Each Sex, Thomas A. Terleph
A Comparison Of Prairie Vole Audible And Ultrasonic Pup Calls And Attraction To Them By Adults Of Each Sex, Thomas A. Terleph
Biology Faculty Publications
Rodent pups of many species emit both ultrasonic vocalizations (USVs) and calls spanning into a lower frequency range, audible to humans (AUDs), yet there has been little systematic comparison of these different call types, or analyses of how they might differ in signal function. Here the spectral and temporal characteristics of USV and AUD pup calls are described for the prairie vole (Microtus ochrogaster), a model used in studies of monogamous mating and biparental care, and a species with an unusually large functional and anatomical representation of auditory cortex. Findings provide a detailed description of each call type, …
Reproduction And Seasonal Activity Of Silver-Haired Bats In Western Nebraska, Keith Geluso, Jeffrey J. Huebschman, Jeremy A. White, Michael A. Bogen
Reproduction And Seasonal Activity Of Silver-Haired Bats In Western Nebraska, Keith Geluso, Jeffrey J. Huebschman, Jeremy A. White, Michael A. Bogen

Silver-haired bats (Lasionycteris noctivagans) were thought only to migrate through Nebraska; however, recent surveys in eastern Nebraska report summer records of females and their young. Our study in western Nebraska also shows that silver-haired bats are summer residents. We discovered the 1st reproductively active L. noctivagans in this part of the state. We caught lactating females and volant young in riparian forests along the North Platte River and in forested areas of the Pine Ridge. Previously, adult males were not known from Nebraska in summer, and only 4 records of L. noctivagans were known from western Nebraska during …
Seasonal Activity And Reproduction In Bats Of East-Central Nebraska, Kenneth N. Geluso, Russell A. Benedict, Francis L. Kock
Seasonal Activity And Reproduction In Bats Of East-Central Nebraska, Kenneth N. Geluso, Russell A. Benedict, Francis L. Kock
Biology Faculty Publications
Information on seasonal activity and reproduction is presented for seven species of bats inhabiting east-central Nebraska (Eptesicus fuscus, Myotis septentrionalis, Nycticeius humeralis, Lasionycteris noctivagans, Lasiurus borealis, L. cinereus, and Pipistrellus subflavus). Early and late dates of capture show five species active in the state for longer periods than previously reported. During some years, E. fuscus and M. septentrionalis emerge from winter torpor in March and feed on insects. Some E. fuscus inhabiting a floodplain forest in summer use houses in nearby towns as hibernacula, and year-round use of buildings by E. fuscus is substantial compared to other species of bats. …

TERRAPENE CAROLINA CAROLINA (Eastern Box Turtle). REPRODUCTION. Female Terrapene carolina containing oviductal eggs have been recorded in Virginia from 26 May to 25 July (Mitchell, in press. The Reptiles of Virginia. Smithsonian Inst. Press, Washington, D.C.). Other reports of reproduction in Terrapene (see list in Ernst and McBreen 1991. Cat. Amer. Amphib. Rept. 512.1-512.13) indicate that nesting occurs in late spring and early summer throughout its range.
