WL Plant Data		

Column title	Definition	Description

plt	Unique Identifier	Plant Individual

year	Year sampled	2007 or 2008

av.dam	Average proportion flowerhead area damaged over all flowerheads produced per plant	Average is of four quarters of the receptacle scored for damage and converted to a proportion. See full explanation in associated journal article.

no.flw	Number of flowerheads	Total number of buds that reached anthesis (flowered)

n.fl.sds	Number of flowerheads with successful seed set	Only includes flowerheads from which seeds were counted

plt.gsd	"Number of ""good"" seed produced per plant"	Sum of all seeds that appeared fully developed and with minimal to no insect feeding damage produced from all flowerheads on a plant 

dam	Apical Damage Treatment	"nd: apical flowerhead undamage, protected by insecticide; d: apical flowerhead damaged, received water treatment (see full explaination in associated journal article)"

ins	Insecticide Treatment	i: flowerheads protected with insecticide (reduced herbivore pressure); ni: flowerheads received water treatment (ambient herbivore pressure)

trt	Treatment	"Combined 2x2 treatment: ndi, ndni = no apical damage under reduced and ambient herbivore pressure; di, dni = apical damage under reduced and ambient herbivore pressure"

ap.hd	"Number of ""good"" seeds produced by the apical flowerhead"	Seeds that appeared fully developed and with minimal to no insect feeding

o.hds	"Summed total number of ""good"" seed produced by all non-apical flowerheads "	Seeds that appeared fully developed and with minimal to no insect feeding

n.hds	Total number of flower buds per plant	All buds greater than or equal to 2-mm in diameter

r.diam	Basal rosette diameter	Calculated as average of two perpendicular measurements

n.br	Number of branches	Branches from the main stem greater than 1 cm length

plt.ht	Plant height	"in cm, to the base of the highest flowerhead"

pnt.flw	Proportion of non-apical flower buds that flowered	Calculated as: no.flw/n.hds

pnt.ohds	Proportion of seed production from non-apical flower heads	Calculated as: o.hds/plt.gsd

sds.flhd	"Average number of ""good"" seeds produced per total flowerheads"	Calculated as: o.hds/no.flw

sd.fh.sd	"Average number of ""good"" seeds produced per seed-producing flowerhead"	Calculated as: o.hds/n.fl.sds
