Cary's Dave Strayer will present a lecture on our planet's inland waters and the rich diversity of life that they support. We think of Earth as "the blue planet" because oceans cover 71% its surface. But there are other waters on our planet – the innumerable lakes, ponds, puddles, marshes, rivers, streams, and ground waters that together make up inland waters.
Inland waters cover a mere 1% of Earth's surface. They are highly varied in size, shape, permanence, and water chemistry. A great range of environmental conditions and partial isolation has resulted in biological diversity out of proportion with their size. For instance, 1/3 of all of the world's known fish species live in inland waters.
