Amphibian Research at the University of Connecticut
Dayton, OH, December 14, 2007 - Kristiina Hurme of the University of Connecticut (Storrs, CT) is using NexSens micro-T temperature loggers in Panama to study tadpole growth and behavior in a Neotropical frog, Leptodactylus insularum.
This large frog is unusually social, with tadpoles forming dense schools of 4,000-5000 individuals and adult females attending and defending these schools. The function of this attendance is not fully understood, and females may be leading their offspring to different microhabitats with temperatures suitable for optimal development.
Current research has shown that minor temperature fluctuations can have a profound impact on amphibian behavior, activity, and development rates. For example, in frogs and toads, increased temperatures speed up egg and larval development rates, which can minimize the amount of time spent in these vulnerable stages. However, in warm climates, available microhabitats can quickly reach lethal temperatures.
Data collected from the micro-T loggers is being used to generate a thermal map of a temporary pond, in an attempt to understand the temperature ranges that the adults and tadpoles prefer.
About NexSens Technology - Recognizing the need for real-time environmental data, NexSens Technology, Inc was started in 1999 and is quickly becoming the preferred supplier for environmental researchers. The company's unique focus on water quality and weather sensors gives researchers valuable system features and capabilities not found in generic data logging equipment.
