3.1 All data from ALA

3.1.1 Species richness

Figure 1: Map showing species richness estimated of Mygalmorphae spiders. Left: All data from the cleaned dataset is used i.e contains citizen science data (basis of record == HUMAN_OBSERVATION) Right: Only expert data is used (basis of record == PRESERVED_SPECIMEN only)

Note

There was no evidence for spatial clustering in species richness in either the combined dataset or in the preserved specimen only dataset (Table 1).

Table 1. Summary statistics for species richness in both datasets

Dataset	Z statistic	P value	N species	N observations
Citizen Science + Preserved Specimen	-0.00087	0.35	219	6051
Preserved Specimen only	-0.00092	0.27	213	4663

3.1.2 Weighted endemism

Figure 2: Map showing weighted endemism estimated of Mygalmorphae spiders. Left: All data from the cleaned dataset is used i.e contains citizen science data (basis of record == HUMAN_OBSERVATION) Right: Only expert data is used (basis of record == PRESERVED_SPECIMEN only)

Note

There was some evidence for spatial clustering in weighted endemism in the preserved specimen only dataset (Table 2).

Dataset	Z statistic	P value	N species	N observations
Citizen Science + Preserved Specimen	-0.00087	0.560	219	6051
Preserved Specimen only	-0.00092	0.015	213	4663

3.1.3 Corrected weighted endemism

Figure 2: Map showing corrected weighted endemism estimated of Mygalmorphae spiders. Left: All data from the cleaned dataset is used i.e contains citizen science data (basis of record == HUMAN_OBSERVATION) Right: Only expert data is used (basis of record == PRESERVED_SPECIMEN only)

Note

There was some evidence for spatial clustering in corrected weighted endemism in the preserved specimen only dataset (Table 3).
