The number of samples and a proxy of abundance calculated as (unique number of captures/number of sampling nights) × (length of the river surveyed) based on Hawke et al.²¹; Ho—observed heterozygosity; He—expected Hardy-Weinberg heterozygosity; F_IS—inbreeding coefficient.
Note that small sample sizes in Mitta-Mitta below the dam and Eucumbene above the dam (both 4 individuals) are likely to result in unreliable estimates of diversity.
SE standard error, NSW New South Wales.
*Microsatellite data.
**Comparable estimates are not available due to different survey techniques see Kolomyjec et al.^31,53,55.
