Female Reproductive Traits In Selected Arkansas Snakes, Stanley E. Trauth, Robert L. Cox, Walter E. Meshaka Jr., Brian P. Butterfield, Anthony Holt
Journal of the Arkansas Academy of Science
Female reproductive characteristics of 17 genera of Arkansas snakes (27 species and subspecies) were examined. Most of the snakes (n= 495) were collected over a 10-year span (1984-1993). Methods used to estimate clutch and/or litter size were as follows: 1) counts of previtellogenic ovarian follicles,2) counts of vitellogenic ovarian follicles,3) counts of oviductal eggs or embryos, 4) counts of corpora luteal scars, and 5) counts of neonates from egg clutches or litters. In several species, Method 1 tended to overestimate clutch size as determined by Method 2 by as much as 100% (e.g., in Diadophis punctatus, Elaphe obsoleta, and Lampropeltis …

Reproductive Cycles In Two Arkansas Skinks In The Genus Eumeces (Sauria: Scincidae), Stanley E. Trauth
Reproductive Cycles In Two Arkansas Skinks In The Genus Eumeces (Sauria: Scincidae), Stanley E. Trauth
Journal of the Arkansas Academy of Science
Reproductive cycles of the southern coal skink (Eumeces anthracinus pluvialis) and the five-lined skink (E. fasciatus) were studied by examining museum specimens collected in Arkansas. Histological preparations of testes from each species revealed eight spermatogenic stages. Male coal skinks produced sperm by late February, at least one month before male five-lined skinks. Height of the testicular cycle (maximum sperm production-stage 6 = spermiogenesis) in E. a. pluvialis occurred in March and early April, whereas in E. fasciatus, spermiogenesis reached a peak in May. Testicular recrudescence began in late May in E. a. pluvialis and mid-July in E. fasciatus. The reproductive …

Unhatched Eggs In Nests Of Red-Cockaded Woodpeckers, Warren G. Montague, Claudia F. Bailey, Joseph C. Neal, Douglas A. James
Unhatched Eggs In Nests Of Red-Cockaded Woodpeckers, Warren G. Montague, Claudia F. Bailey, Joseph C. Neal, Douglas A. James
Journal of the Arkansas Academy of Science
During 1991 and 1992, nests of Red-cockaded Woodpeckers (Picoides borealis) were monitored in the Ouachita National Forest in Scott and Polk counties of west-central Arkansas. Nests in three additional woodpecker areas in Arkansas and Oklahoma were also monitored in 1992. Of 92 eggs laid in 27 nesting attempts in the Ouachita National Forest, 18 (19%) failed to hatch. When viewed in the cavities, six unhatched eggs were noticeably below average in size for the species and eight were average size. Seven unhatched eggs were removed in 1992 from seven nests in Arkansas and Oklahoma; three eggs showed some embryological development …

Journal of the Arkansas Academy of Science
We continued field studies of bats in non-cave regions of Arkansas from 1989 to present and utilized specimens submitted to the Arkansas Department of Health Rabies Laboratory to establish Arkansas range extensions for the eastern smallfooted bat (Myotis leibii) and northern long-eared bat (Myotisseptentrionalis). In addition, we documented additional county records for the silver-haired bat (Lasionycteris noctivagans), hoary bat (Lasiurus cinereus), southeastern bat (Myotis austroriparius), and Rafinesque's big-eared bat (Plecotus rafinesquii).

Reported Animal Rabies In Arkansas: 1982-1990, Gary A. Heidt, David A. Saugey, Laura Chandler, Karen D. Stone
Journal of the Arkansas Academy of Science
Reported animal rabies in Arkansas is reviewed for the years 1982-1990; providing an update from 1950-1981 (Heidt, 1982). Total cases ranged from 39 in 1990 to 168 in 1986, with a mean of 123.1. Wildlife accounted for 93.4% of the total cases. A total of 16 kinds of mammals has been implicated in reported rabies (individual species of foxes and skunks have been combined). The four taxa accounting for the highest incidence are: skunks (82.6%); bats (10.1%, all seven species combined); cattle (2.8%); and dogs (1.5%). Skunks, the most prominent species, ranged from 71.8% in 1990 to 90.2% in 1987. …
