Why do field biologists use the binomial nomenclature Lithobates sylvaticus universally?

To prevent confusion that common names create across regions and dialects.

The adoption of binomial nomenclature, utilizing the genus and species combination like *Lithobates sylvaticus*, is a fundamental practice in biology, especially for field research and conservation efforts. Common names for organisms frequently vary significantly based on local dialect, region, or even among different groups of people within the same area. This can lead to ambiguity or outright confusion where one common name might refer to several different species, or vice versa. Using the precise scientific designation ensures that researchers communicating data—whether on migration timing, breeding calls, or population counts—from disparate locations like Maine, Alaska, or Illinois, are all referencing the exact same organism, thereby ensuring data integrity and comparability under a universal scientific umbrella.
