Evaluarea particularităților fenologice ale amfibienilor ecaudați (fam. Ranidae, Bufonidae) în contextul schimbării factorilor de mediu în Republica Moldova

Abstract

The evaluation of the results obtained in this paper allows us to highlight certain biological-ecological particularities and behavioral features of the annual reproductive cycle of studied populations of ecaudata amphibians (family Ranidae, Bufonidae) in the ecosystems of the Central Forests of the Republic of Moldova. It has been established that the evaluated species, as a rule, are able to fully realize their reproductive potential and to achieve an expected reproductive success, which ensures their perpetuation in time and space. The reproductive strategies of these species are strictly adaptive and were formed during evolution in order to ensure population survival in certain living conditions. At the same time, with the deterioration of habitats due to the action of various factors of anthropogenic origin, many of the populations of these species are not able to quickly change their complex of adaptations; which leads to their extinction and the compromise of the general number of species in certain areas of the range. Therefore, in many regions of the area many species of these amphibian families are protected both locally and regionally, as well as in Europe (Rana dalmatina, Rana temporaria, Bufo viridis, Bufo bufo, etc.).
