Back To Estill Fork Saturday

We'll go out to Estill Fork Saturday to collect telescope and scarlet shiners. Once again we seem to be lucky with the weather, the prediction is for high in the 70's F and sunny. There hasn't been rain since last weekend so water level should be manageable.

Brittany has been doing more statistical analysis of data from the 11-KT scarlet shiner experiment. Females exposed to 11-KT compared to wild-caught females had significantly larger brain weight/body weight ratios in a U-test, with p<0.001. Males exposed to 11-KT compared to wild-caught males also had a significantly larger ratio, but only with p=0.05. This makes sense, because the wild-caught males have been influenced by their endogenous 11-KT, while wild-caught females would have almost no endogenous 11-KT. This seems to be a good story, and the results encourage me to go on to a more ambitious experimental manipulation later this year.
