I’m reminded of one of Margaret Cramer’s ironic insights

Recent science news mentions a new dynamic way of studying aquatic-species districts in American streams. Things change, after all, and it’s about time that someone realized that colonies move all the time. Dynamism and mapping seem like opposing concepts.

Populations move, yeah, and a good deal faster than beaurocrats, in Margaret Cramer’s experience. ┬áTo wit:

I grew up, with my parents and four siblings, in South Champion, New York. One branch of a stream named Sandy Creek flowed through the property. Its water was pure enough to make a home for fingerling salmon on their way to adulthood, when they would get fat and tasty in Lake Ontario.

The naturalist in Mother raised her ire when she noticed that the local cheese factory had begun releasing — illegally — whey into the stream. She read lots of the community-education materials published by Cornell University, and figured she should warn authorities about danger to the salmon.

She did that. Successfully, to no visible effect. When at last someone came to check out the situation, he earned his wage for the day by observing that Mother had been mistaken: “No salmon here at all.”
