Distributional Survey Of The Bird-Voiced Treefrog, Hyla Avivoca (Anura: Hylidae), In Arkansas, Stanley E. Trauth
Distributional Survey Of The Bird-Voiced Treefrog, Hyla Avivoca (Anura: Hylidae), In Arkansas, Stanley E. Trauth
Journal of the Arkansas Academy of Science
A field study of the bird-voiced treefrog, Hyla avivoca, was conducted in Arkansas during the summer of 1991. A total of 75 separate sites in 23 counties was visited. Males with their distinctive whistle-like calls were listened for at night at each site. Breeding colonies of Hyla avivoca were found in four of the six major river basins; the study established three new county records. Currently, this species has been documented at 14 sites in 10 counties; in very few situations were the treefrogs locally abundant (voucher specimens deposited in the Arkansas State University Museum of Zoology). Habitat perturbation and …

Reproduction In The Western Mud Snake, Farancia Abacura Reinwardtii (Serpentes: Colubridae), In Arkansas, John W. Robinette, Stanley E. Trauth
Journal of the Arkansas Academy of Science
The reproductive cycle of Farancia abacura reinwardtii was studied using samples of snakes collected throughout Arkansas from 1985 to 1991 ;museum specimens were also examined. The right testis of 22 males was examined by light microscopy. Histological analysis of the testis indicated a postnuptial spermatogenic cycle. Testicular recrudescence begins in late May with sperm production peaking in late summer; sperm over winter in the ductus deferens. Ovarian follicles of 22 females were measured and counted; two follicular sizes were noted. In those undergoing primary vitellogenesis, a maximum size of 6.5 mm was reached; those exhibiting secondary vitellogenesis ranged in size …
