Given the reference text below, what problem do Marbled newts' face?

The marbled newt is typically found in habitats characterized by hilly and forestry terrain, away from open and exposed areas.[2] Marbled newts live in temporary habitats, such as ponds, that are subject to change depending on the climate conditions of the region. When rainfall is high and the temperature is lower, typically in the fall and winter months, adult marbled newts stay in the ponds. However, these shallow ponds are subject to drought in warmer spring and summer months, which forces the marbled newts to remain on land. Due to this constant change in the habitat conditions, marbled newts have the ability to adapt to different climatic conditions and habitat changes.[3]

Marbled newt is forced to remain on the land due to droughts.
