A Pacific tree frog (green morph) sitting on a sunflower leaf stem, Nanoose Bay British Columbia. The Pacific tree frog grows up to two inches from snout to urostyle. The males are usually smaller than the females and have a dark patch on their throats. The dark patch is the vocal sac, which stretches out when the male is calling. Pacific tree ...
The gray treefrog (Dryophytes versicolor) is a species of small arboreal holarctic tree frog native to much of the eastern United States and southeastern Canada. [ 2 ] It is sometimes referred to as the eastern gray treefrog , northern gray treefrog , [ 3 ] common gray treefrog , or tetraploid gray treefrog to distinguish it from its more ...
It is known under numerous common names, including common tree frog, four-lined tree frog, golden tree frog [2] or striped tree frog. Many past authors have united it with the common Indian tree frog in P. maculatus (or Rhacophorus maculatus , as was common in older times), but today they are generally considered distinct species.
Tree frogs are members of these families or genera: Hylidae, or "true" treefrogs, occur in the temperate to tropical parts of Eurasia north of the Himalayas, Australia and the Americas. Rhacophoridae, or shrub frogs, are the treefrogs of tropical regions around the Indian Ocean: Africa, South Asia and Southeast Asia east to Lydekker's line.
The diet of Cope's gray treefrog primarily consists of insects such as moths, mites, spiders, plant lice, and harvestmen. Snails have also been observed as a food source. Like most frogs, Dryophytes chrysocelis is an opportunistic feeder and may also eat smaller frogs, including other treefrogs. [24]
The "true" tree frogs belong to the family Hylidae, but members of other frog families have independently adopted an arboreal habit, a case of convergent evolution. These include the glass frogs (Centrolenidae), the bush frogs (Hyperoliidae), some of the narrow-mouthed frogs (Microhylidae), and the shrub frogs (Rhacophoridae). [ 111 ]
Pine Barrens tree frogs are rarely encountered in sites where nonnative amphibians, such as bullfrogs, and nonnative fish are present, suggesting that they are poor competitors. As a consequence of this, D. andersonii populations found in or near developed and agricultural areas are believed to be the most at risk due to the greater presence of ...
The frog has been found to defecate viable seeds and likely helps in the spread of the plants it consumes. [ 3 ] The plants Erythroxylum ovalifolium and Maytenus obtusifolia both contain toxic alkaloids and terpenes , [ 7 ] [ 8 ] and Xenohyla truncata has been found to excrete from its skin the chemical compound N-phenyl-acetamide , which is ...
