Objective: To compare eighteen samples of Forest frog's oviduct from different regions of northeast China, in order to fomulate the quality evaluation standard.
Methods: According to the documents, comparing the target constituent of Forest frog's oviduct, including the mositure, ash, protein, lipid and expansibility were analysed.
Results: It was similar to the chemical constituent in Forest frog's oviduct from different habitiat of northeast China.
Conclusion: The germplasm of this species is stable.

The forest frog ( Pollas) is a traditional medicinal source rich in active protein compounds. In order to extract these compounds, six extraction methods were employed, including freeze-thaw and stirring techniques. Three different solvents were utilized in this process: 0.

Sexual communication often takes place in networks with multiple competing signalers being simultaneously assessed by mate choosers. Altered sensory conditions, such as noise and light pollution, can affect communication by altering signal production and perception. While evidence of sensory pollution affecting sexual signaling is widespread, few studies assess impacts on sexual signaling during rival interactions as well as mate choice, let alone whether urban and non-urban populations have diverged in their response.

Thermoregulatory behaviour determines an organism's body temperature and therefore its physiological condition, and may differ for organisms situated across climate gradients. Species' preferred or selected temperatures may be higher in warmer locations-referred to as coadaptation-or lower in warmer temperatures-countergradient variation. Here, we tested if rainforest amphibians exhibited coadaptation or countergradient thermal selection across an underappreciated spatial climate gradient (vertical height from forest floor to canopy) and separating diel activity (diurnal versus nocturnal behaviour).
