AI Thread Summary
The discussion centers on the lack of a standardized definition for femur length in the life sciences, particularly regarding its measurement across different species. The inquiry references the International Union of Pure and Applied Biology (IUPAB) but finds limited activity and guidance from this group. The specific concern is a 5% measurement difference between two species, with existing references failing to provide a clear measurement protocol. Various links are shared to illustrate the diversity in femur measurement standards among mammals. The consensus suggests that researchers should either adopt the measurement methods used in existing literature or develop their own consistent approach, ensuring internal consistency for data analysis within their specific study context.

Google "IUPAB" and get http://www.google.com/search?hl=en&...nion+of+pure+and+applied+biology"&btnG=Search , a short list indicating very little activity.

Is there some sort of professional standards group recommending practices and nomenclature in the life science fields?

The specific question I have is, "Is there a 'standard' definition of femur length?" See http://www.loris-conservation.org/d...easurement/11a-figures_limb_measurements.html ,
"Leg measurements, primate standard, according to Schultz, 1929:

Thigh length (length of femur): from trochanterium summum to femorale, parallel to the longitudinal axis of femur.
Ischium-knee (Osman Hill, Phillips 1932). No exact definition given."


There's ~5% difference in the two measurements which is the difference between two species between which I'm trying to distinguish, and my references don't specify a measurement protocol, hence the question about IUPAB; is there a "convention" that is understood by people in the life sciences that I can "safely" assume?

That's what I was afraid of --- the "no."
 
You've already reasearched cladistic values for your species - ie., since you "know" there is a 5% difference, use the method the original researchers used in papers you must have already read.

Or define your own method, unless you're going to compare your data to someone elses'. As long as you are internally consistent your data analysis will be acceptable for use amongst the species you study.

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
