What did we learn from amphibians throughout our project?
The raising global temperature is a challenge for everyone, but for amphibians it translates into shortened life. This threat adds to the already devastating effects caused by habitat disappearance, pollution or introduced species, throughout the globe. It will be our responsibility to create and protect suitable habitats, to ensure their survival. The most affected will be those species that already have a short lifespan and survive within limited ranges. In Romania, we estimate that spadefoot toads, the fire-bellied toad, green frogs (edible and marsh frogs) and the Danube crested newt will be the most affected. These species were evaluated as "Least concern" by IUCN, meaning that the global estimated risk of their extinction is low. However, the spadefoot toads already live at the limits of their distribution range in our country, such as the persistence of viable populations in this area will be even more challenging, in the absence of adequate conservation measures.

Danube crested newt
Green frogs
While we found our answers, new questions arise, to be addressed by future research: what is the role of sexual selection in shaping growth and senescence patterns? is the variability of these traits a good indicator of species ability to adapt and survive in new environments? are growth and senescence patterns comparable in amphibians and reptiles?
