As complex life cycle parasites, Lecithaster sp. and Capillaria parophrysi require multiple host species throughout their development. Extrapolating from parasite counts on Pacific herring and seven other fish species collected from Puget Sound from 1880 to 2019, Chelsea Wood et al. found that the abundance of three-host parasites, such as Lecithaster sp., negatively correlated with rising average annual sea temperatures; the abundance of two-host parasites, such as C. parophrysi, was largely stable. Noting that fish and other marine vertebrates are especially vulnerable to climate change, Wood et al. observed that all three-host parasites in the study depend on at least two vertebrate species, while all two-host parasites depend on only one, suggesting that Which choice most logically completes the text?
