Relationship of recent systematics of frogs (Anura) and research efforts
 MRÁZKOVÁ, Nikola
Over the last few decades there has been a confusion in the classification system of organisms with the development of molecular and genetic methods. Life is currently perceived from a different perspective than in the past due to different methods, and old, standard systems have significantly changed as a result of such alteration. As a consequence, it is harder and harder to distinguish which taxonomic changes are caused by objectively better recognition of biodiversity and which seem to be only subjective opinions of particular taxonomists. Results show a significant growth in the number of genuses in observed families of frogs (Anura) in the aforementioned period (2000-2017) while the research efforts of taxonoms were proved to be the most relevant factors causing such increase in diversity with respect to genuses.
