Beyond DNA barcoding: The unrealized potential of genome skim data in sample identification

K Bohmann, S Mirarab, V Bafna, MTP Gilbert - 2020 - Wiley Online Library
Genetic tools are increasingly used to identify and discriminate between species. One key
transition in this process was the recognition of the potential of the ca 658bp fragment of the …

Host body size, not host population size, predicts genome-wide effective population size of parasites

J Doña, KP Johnson - Evolution Letters, 2023 - academic.oup.com
The effective population size (N e) of an organism is expected to be generally proportional to
the total number of individuals in a population. In parasites, we might expect the effective …
