Fig 1.
Density plots of (A) year and (B) day of year of plant occurrence records within Norway for observations and specimens.
Table 1.
A. The number of occurrence records by phylum within each phylum and basis of record.
The proportion of the total number of division occurrence records by basis of record is shown in parentheses. B. The number of species recorded by each basis of record within each division. The proportion of the total number of species recorded by each record type shown in parentheses.
Fig 2.
(a) Number of human observation and preserved specimen records of each species. Species are plotted with symbols denoting their taxonomic class (Bryophyta and Marchantiophyta grouped as bryophytes). (b) The ratio of number of observations to number of specimen records for each species grouped by taxonomic class. Boxes represent interquartile ranges, with whiskers 1.5 times this range, and points showing species outside the range. The median is shown by a black line. Values above one show species with more observation records than specimen records. Vertical lines divide classes within the three phyla. (c) Species rank-abundance plot for each record type in the Norwegian Embryophyta dataset, showing the number of records (note log10 y-axis) for each species plotted against the species’ rank when ordered from most to least abundant within each record type. Table 2 gives the identity of the 10 most abundant species per record basis. (d) Recorder rank-abundance plot for each record type showing the log number of records made by each recorder, plotted against the recorders’ rank when ordered from the most to least abundant within each record type. S1 Table gives the identity of the 10 most abundant recorders per record basis.
Table 2.
The number of occurrence records of the 10 most abundantly recorded species by each record type.
The proportion of the total number of occurrences within each record type represented by each of these species is shown in parentheses. The growth form of the species is shown, as is the range, calculated as the number of 10 × 10 km cells in which the species was recorded as any record type.
Fig 3.
The number of species occurrence records of each record type plotted against the geographic range, here estimated as the number of 10x10 km grid cells within which that species had been recorded (as any record type).
Outlying species are plotted as square points and labelled.
Fig 4.
Two dimensional kernel densities showing the probability distribution function (expressed as a percentage) of species occurrences within phyla and record types.
Darker shades denote a higher probability of a given occurrence being at that location. Note that the colour scales differ between phyla, but are the same within phyla. Locations referred to in the text are labelled in top right panel; Trondheim (T), Kongsvoll (K) and Oslo (O).
Fig 5.
Density plot showing distributions of species occurrence data by record type along the three dominant climatic variables and human population density across Norway.
The dashed lines show the total climatic or human population density space within Norway. Rows denote different phyla, while columns show different variables.
