Natural history and ecology of Jollyville Plateau salamanders (Eurycea tonkawae)

What is it about?

This study summarizes results from surveys of <i>Eurycea tonkawae</i> from across its range to get a better understanding of its natural history and ecology. These salamanders exhibit seasonal patterns in reproduction, although females may lay more than one clutch of eggs during their breeding season. Longevity is at least eight years for surface-dwelling populations. The median age of a recaptured adult was around two years, with an average size of 32 mm in length (excluding the tail). Results from population modeling emphasize the importance of stream flow and seasonal effects on their population dynamics, as well as their ability to rebound following severe drought and dry conditions.

Why is it important?

The species lives in a relatively small area and is threatened by urbanization, which causes water pollution, changes is stream ecology, and changes in water quantity. Learning about how the species responds to natural environmental change helps us better understand and respond to anthropogenic effects.
