“…Finally, Lohmus & Bjorklund (2015) explored the sensitivity of host-parasite parameters to small changes in temperature. As a base, they used a model by Taylor et al (2015) on a multihost trematode life cycle modified to include temperature dependence in four parameters: the reproductive rate of the first intermediate host, the reproductive rate of the parasite, the mortality of the first intermediate host, and the transmission rate of infection to the first intermediate host.…”

Climate change affects ecological processes and interactions, including parasitism. Because parasites are natural components of ecological systems, as well as agents of outbreak and disease-induced mortality, it is important to summarize current knowledge of the sensitivity of parasites to climate and identify how to better predict their responses to it. This need is particularly great in marine systems, where the responses of parasites to climate variables are less well studied than those in other biomes. As examples of climate's influence on parasitism increase, they enable generalizations of expected responses as well as insight into useful study approaches, such as thermal performance curves that compare the vital rates of hosts and parasites when exposed to several temperatures across a gradient. For parasites not killed by rising temperatures, some simple physiological rules, including the tendency of temperature to increase the metabolism of ectotherms and increase oxygen stress on hosts, suggest that parasites’ intensity and pathologies might increase. In addition to temperature, climate-induced changes in dissolved oxygen, ocean acidity, salinity, and host and parasite distributions also affect parasitism and disease, but these factors are much less studied. Finally, because parasites are constituents of ecological communities, we must consider indirect and secondary effects stemming from climate-induced changes in host–parasite interactions, which may not be evident if these interactions are studied in isolation. Expected final online publication date for the Annual Review of Marine Science, Volume 13 is January 3, 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…A large number of host–parasite models can be found in the literature (Schmid‐Hempel, ); however, the scope of this paper does not involve a review of different models. Nevertheless, to exemplify the inherent complexity in host–parasite systems we have chosen to use the recent model of Taylor, White & Sherratt () depicting a host‐changing parasite life cycle, similar to a trematode (i.e. Diplostomum spp).…”

Climate change-related factors are predicted to affect aquatic environments in many ways. Fish physiology, immunology, behaviour, and parasite-avoidance strategies are likely to be affected by climate change and this may lead to ecosystem-level changes. Parasitic organisms that exploit fish are also likely to be affected by climate change, both directly and via climate effects on their hosts. It is possible that climate change will alter the prerequisites for parasite transfer, for example, through changes in phenological relationships, and/or change the direction and pressure of selection in host-parasite relationships. Our review indicates strong multifactorial effects of climate change on fish-parasite systems. Increased water temperature is, on the one hand, predicted to enhance parasite metabolism, resulting in more rapid spread of parasites; on the other hand, the occurrence of some parasites could also decrease if the optimal temperature for growth and transmission is exceeded.
