Climate Change Causes Ectotherms to Produce a Lost Generation

by Anna Alquitela

Ectotherms are organisms that rely on environmental heat sources to maintain their body temperatures. The timing of reproduction in these organisms has much to do with their available thermal time windows. According to Van Dyck et al. (2015), the warming climate could cause an increase in the annual number of generations of ectotherms, but this response is potentially maladaptive, leading to a developmental trap; if an organism reproduces at the end of its reproductive season, there is a good chance that the new generation will die and the energy used to produce that generation would have been in vain.
