Gray treefrogs (Hyla chrysoscelis) and Plains narrowmouth toads (Gastrophryne olivacea
) are also known to use the pond for breeding (tadpoles observed), and may live in the nearby prairie.
All species were classified into one of five categories: (1) western: species that occur predominantly west of about 98[degrees] west longitude (e.g., roadrunner Geococcyx californianus), (2) central: species that are predominantly in the central plains area (e.g., Great Plains narrow-mouthed toad Gastrophryne olivacea
), (3) widespread: species that occur in virtually all states and provinces in North America north of Mexico (e.g., pied-billed grebe Podilymbus podiceps), (4) eastern-western: species that are not widespread but which occur in both the east and in the west (e.g., Mexican freetail bat Tadarida brasiliensis), (5) eastern: species that are exclusively or predominantly found in the east (e.g., alligator Alligator mississippiensis).
All anuran species known to occur in Nebraska except Gastrophryne olivacea, the Great Plains Narrow Mouth Toad, were recorded during the survey period.
All anuran species known to occur in Nebraska (Lynch 1985) except Gastrophryne olivacea, the Great Plains Narrow Mouth Toad, were recorded during the survey period (Table 1).
-- The relationships of body mass and developmental stage to acid tolerance were examined in tadpoles of three species of anurans from central Texas: Bufo woodhousei, Bufo valliceps, and Gastrophryne olivacea
. Significant differences in survival time at low pH occurred among all three species (survival time of Bufo valliceps > Bufo woodhousei > Gastrophryne olivacea
Species that were associated primarily with grasslands were: Gastrophryne olivacea
, Pseudacris triseriata, Ophisaurus attenuatus, Lampropeltis triangulum, Pituophis cantenifer, Tantilla gracilis and Tropidoclonion lineatum.
Great Plains narrowmouth toad (Gastrophryne olivacea
) and Texas spotted whiptail (Cnemidophous gularis) were the dominant species encountered making up 61 and 10% of total captures, respectively.
