摘要: Amphibian evolution spans over 350 million years, consequently this taxonomic group displays a wide, complex array of physiological adaptations and their diverse modes reproduction are prime example. Reproduction can be affected by taxonomy, geographic altitudinal distribution, environmental factors. With some exceptions, amphibians categorized into discontinuous (strictly seasonal) continuous breeders. Temperature its close association with other proximate genetic factors control via tight relationship circadian rhythms which drive hormonal responses to the environment. In recent times, has directly or indirectly lead decline group. Conservationists tackling rapid loss species through wide range approaches including captive rescue. However, there is still much learned about mechanisms reproductive requirements in order fabricate species-appropriate environments that address variety strategies. As groups, assisted technologies monitoring tools such as ultrasound, hormone analysis body condition indices assist conservationists optimizing husbandry breeding. review we discuss ovarian different being used monitor female reproduction.
