Demographic data of Cynoglussum officinale at 3 sites in the native and introduced ranges from 2004 - 2007

This dataset contains demographic data for Cynoglossum officinale L. (Boraginaceae) collected at 3 sites in its native range and 3 sites in the introduced range from 2004 to 2007 (sampled 2 times/year). These data were used to parameterize integral projection models to investigate differences in life history between the native and introduced range (Williams 2009) and to investigate the impacts of native specialist insects and small-scale disturbances on population growth (Williams et al. 2010). Individual fate and size data of marked and mapped individuals in 1 m x 10 m transects were collected at 2 censuses per year (spring and summer), seed production was measured during the summer census; new seedlings were added each spring. These are all the data required to parameterize a population model (matrix model or integral projection model). This dataset includes 3 tables: 1) location of individual (to the nearest decimeter); 2) fate, size and amount of leaf herbivory at each census; 3) seedling fate in each transect (the fate of individuals was not followed).
