Abstract
The present study explores the thermal adaptability in pathogens and tries to find out a relationship between climate warming and diseases. The phenotypic evolutionary analysis of a multi-pathogen system with temperature dependent disease transmission and virulence leads to a possibility of the bistable behaviour of pathogens on temperature scale. Bistability allows the establishment of low and high temperature specialist pathogen strains in a host population. It is observed that bistability can be realized in a host-pathogen system when survival of host and pathogen is possible on a sufficiently wide range of temperature. On the other hand, if host or pathogen survival remains temperature limited, host is susceptible to only one of the either specialists. For the proposed model with density dependent host mortality, we have observed the dimorphic existence of pathogens on moderately warm temperature range only. An advanced level multivariable time-series plot of malaria epidemic in Manipur (India) confirms the bistable behaviour of malaria infection on the temperature scale. Here, we present a novel investigation about thermal adaptability and diseases. We have tried to test the validity of the theory of range expansion and range shifts about climate and diseases.
