Spot fin Chub Spawning in Tellico River
-
For a little more than 10 years, Conservation Fisheries has been working to re-establish spotfin chub into the Tellico River in eastern Tennessee. These spectacular, turquoise minnows (only the males develop this color and only during summertime spawning), are highly specialized and closely associated with clean, current swept, bedrock habitats. During spawning season, the males become very territorial and stake out crevices in the rocks where the females will ultimately deposit the eggs. While males vigorously defend these territories, they do not provide any direct care to the eggs and larvae. The spotfin chub is federally threatened.

Stability and Diversity of Ecosystems
-
Understanding the relationship between diversity and stability requires a knowledge of how species interact with each other and how each is affected by the environment. The relationship is also complex, because the concept of stability is multifaceted; different types of stability describing different properties of ecosystems lead to multiple diversity-stability relationships. A growing number of empirical studies demonstrate positive diversity-stability relationships. These studies, however, have emphasized only a few types of stability, and they rarely uncover the mechanisms responsible for stability. Because anthropogenic changes often affect stability and diversity simultaneously, diversity-stability relationships cannot be understood outside the context of the environmental drivers affecting both. This shifts attention away from diversity-stability relationships toward the multiple factors, including diversity, that dictate the stability of ecosystems.
