Loading and wrangling data
baseline<-read.csv("baseline.csv")
baseline %>%
replace(is.na(.), 0)->baseline
## Making it into proportions
baseline %>%
mutate_if(is.numeric,
~case_when(.==1~0.5,
.==2~2.5,
.==3~7.5,
.==4~17.5,
.==5~37.5,
.==6~62.5,
.==7~87.5,
.default = as.numeric(.)))->baseline_prop # proportion data
baseline %>%
mutate_if(is.numeric,
~case_when(.>0~1,
.default = as.numeric(.)))->baseline_freq # frequency data (0 & 1)Here we create two different databases:
- An abundance-based (percentages) that consider dominance of species and;
- A presence/absence database, that accounts only for whether each species are present or not in each quadrant (1x1m²)
Creating “plot” variable that group others
For analytical purposes, we need to create a factor that helps us to group quadrants(1x1m²) by plots(10x10m²)
## Coverage data
baseline_prop%>%
pivot_longer(!Species.name, names_to = "quadrant", values_to = "prop") %>% # create a long data with "quadrant" variable
mutate(plot=substr(quadrant, 1,2)) %>%
filter(prop!=0) %>% # filter only species that occurred per quadrant
pivot_wider(names_from = plot, values_from = prop) %>% # back to wide format
arrange(quadrant) %>% # arrange by quadrant
group_by(Species.name) %>%
summarise_if(is.numeric, ~ mean(., na.rm = TRUE)) %>%
mutate(across(where(is.numeric), ~replace_na(., 0)))->baseline_prop_analyses # This creates a table grouping the average occurrence of species by quadrant
## Presence/Absence matrices
baseline_freq %>%
pivot_longer(!Species.name, names_to = "quadrant", values_to = "freq") %>%
mutate(plot=substr(quadrant, 1,2)) %>%
filter(freq!=0) %>%
pivot_wider(names_from = plot, values_from = freq) %>%
arrange(quadrant) %>%
group_by(Species.name) %>%
summarise_if(is.numeric, ~ sum(., na.rm = TRUE)) %>%
rbind(c("AAN_quad", as.numeric(rep(12,4)))) %>% # Here I am adding a line that contains just the the number of quadrants per plot, needed for INEXT analyses, later.
arrange(Species.name) %>%
mutate_at(vars("I1":"F1"), as.numeric)->baseline_inc_freq # relative frequencies n/12
baseline_prop_analyses %>%
mutate_if(is.numeric,
~case_when(.>0~1,
.default = as.numeric(.)))->baseline_freq_raw # presence/abscense dataNow we have three datasets for the specific analyses that come later in this doc. Datasets are: 1) A sp x plot dataset with mean coverages 2) A sp x plot with relative frequencies per plot (0 to 12) 3) A sp x plot with raw presence/absence per plot (0 or 1)
Species accumulation curve via rarefaction, interpolation methods
Here we are using iNEXT package that uses the method of rarefaction/interpolation to estimate species diversity and accumulation curves, based on sample coverage of sample units (plots, in our case)
# Using coverage as frequecy data
iNEXT(as.data.frame(baseline_inc_freq[,-1]), q=c(0,1,2), datatype="incidence_freq")->res_inext
# plot(res_inext) # this function uses ggplot by I prefer the ggiNEXTI suggest that you study the iNEXT vignette to understand what the function generates.
A brief glimpse is:
iNEXT generates a combination of rarefaction and extrapolation curves that permit us ot both estimate the total number of species beyond the observed but also allows to compare plots using extrapolations (estimations).
## Orders of True Diversity
ggiNEXT(res_inext, type=1, facet.var="Assemblage")
In the plot above, the we can see one of the output graphs faceting plots and separating curves of each order of diversity q (0,1,2) where: * When q = 0, this is equivalent to species richness * When q = 1, this is equal to diversity of common species * When q = 2, this is equal to diverity of dominant species
ggiNEXT(res_inext, type=1, facet.var="Order.q", color.var="Assemblage")
The graph above is an inversion of the first, which I like more
## Sample coverage
ggiNEXT(res_inext,type=2, facet.var="None", color.var="Assemblage")
Here we have a clear otion that sample coverage (this means, sample effort) is good enough

Preliminary conclusions
- Samples have in average the similar number of species
- Species accumulation curve at the plot (10x10m) level stabilize for common (q=1) and dominant species (q=2) but is far from enough for rare species (q=0)
- Methods seems adequate to capture diversity of plants at this scale
- Species composition seem to vary a lot at this scale, suggesting underalaying factors such as: founding effects; inter-speciifc competition, etc…
- Beta diversity is largely due to turnover of species, this suggesting that dispersal limitations and local-scale processes govern species assembly
More to do…
