exPt2 Core

This core dataset contains annual fitness measurements for all Echinacea planted in the heritability of flowering time experimental plot (exPt 2). Here is a list of fields in the dataset:

cgPlaId: common garden plant Id (numeric)
row: common garden location coordinate / easting or row coordinate in meters (numeric)
pos: common garden location coordinate / northing or position coordinate in meters (numeric)
yrPlanted: year planted (numeric)
We annually assess the following for each plant:
ld: living during observation year / 1 = yes, 0 = no (binary)
fl: flowering during observation year / 1 = yes, 0 = no (binary)
hdCt: head count / if flowering, count of heads per plant for observation year (numeric) *
achCt: achene count / count of achenes per plant for observation year (numeric) **

* here are the rules for what we consider a head: If a head was measured as normal, bent, tilted or indented (or combinations of those) it will be considered a countable head. (hdStatusCd 1-4,12-16) If a head was listed as dud, crisp, no florets, vertical development, no hd, whole head weird, or gone it is not counted as a head. However, head status is adjusted based on achenes counted: Heads are counted only if the achene count from that head is greater than 0. Heads with 0 achenes are not included in the head count for the plant.

** here is an explanation for negative numbers in acheneCt: We use “-9999” as code for “missing data” in the achCt field for each head. If the plant had multiple heads & a count was missing for one of the heads, -9999 was summed together with the good achene count(s). So far, we don’t have any instances where more than one head has a missing achene count per plant; but if we do, I’ll make a note of it. So if hdCt > 1 & acheneCt < 0 adding 9999 to acheneCt will give you the acheneCt for the heads that are not missing data.
