  • Title: How will global climate change affect parasite-host assemblages?
    Author: Brooks DR, Hoberg EP.
    Journal: Trends Parasitol; 2007 Dec; 23(12):571-4. PubMed ID: 17962073.
    Abstract:
    Parasites are integral components of the biosphere. Host switching correlated with events of episodic climate change is ubiquitous in evolutionary and ecological time. Global climate change produces ecological perturbations, which cause geographical and phenological shifts, and alteration in the dynamics of parasite transmission, increasing the potential for host switching. The intersection of climate change with evolutionary conservative aspects of host specificity and transmission dynamics, called ecological fitting, permits emergence of parasites and diseases without evolutionary changes in their capacity for host utilization.
