After looking at all the responses, I still feel that "niche" is the right word!

As for the new question, I don't know what statisticians might want to say, but this is a basic tenet of hierarchical systems theory. More generally, the more you focus on one hierarchical level, the less you know about others. Ecologists need know relatively little about basic physiology for example.

Subject: [ECOLOG-L] STATISTICS Help again and thanks for all the recent help


Thanks again to everyone who helped with my recent enquiry about tolerance ranges and their mirror-images in the habitat fun-house.

Now, begging your endulgence once again, can anyone help me with background on or explanation of this statistical dictum? Again, I'm working with a fading memory, so I may not remember the exact phrasing.

"The more you know about a population, the less you know about any individual in that population."

Gratefully,
WT
