Species occurrence data
We collated and cleaned the occurrence data of the fish and odonate
species of Bhutan (see Appendix 1 Table S1). We then rarefied the
occurrence of all the fish and odonate species with five or more
occurrences to Euclidean distance of 5km using the SDMtoolbox v2.4
(available fromhttp://sdmtoolbox.org/, Brown
2014, Brown, Bennett and French 2017). We aimed to reduce the negative
influence of the spatial autocorrelation among occurrences on the
species distribution models (Brown 2014, Brown et al. 2017, Galante et
al. 2018), but also to retain the maximum possible number of species
with at least five occurrences. This resulted in 10 fish and 28 odonate
species with small occurrences (n= 5 to 21) for which we built SDMs and
used these for the current study.
