Question

The san marcos salamander, eurycea nana, is a light reddish-brown translucent salamander about 2–5 cm in length. E. Nana is found only in spring lake and a portion of the san marcos river. Which human activity would most likely decrease the ability of the salamanders to survive?.

Answer 1

Human activity would likely decrease the salamanders' survivability is the growth of cities, which has led to greater use of water by people and increased problems of water pollution and sludge buildup.

What leads to the disappearance of the species?

Reducing the flow of water from springs is the biggest threat to the survival of Salamandra San Marcos and other animals and plants dependent on the springs. The growth of cities has led to greater use of water by people and has increased problems with water pollution and sludge buildup. The introduction of non-native species is also a threat because they can destroy aquatic vegetation, attack endangered animals or compete with them for food.

With this information, we can conclude that human activity would likely decrease the salamanders' survivability is the growth of cities, which has led to greater use of water by people and increased problems of water pollution and sludge buildup.
