As discussed at length in Waldock et al. , selecting thresholds of environmental criteria for defining species distributions should take into account the scale and accuracy of the climate model used. While laboratory experiments may indicate the upper and lower limits of Ae. albopictus survival and development, these conditions will not be found uniformly across one grid square in any model output. Even with relatively high-resolution model output of 50 km, micro-climates will exist within each grid square. The thresholds for our environmental criteria have been selected based on comparison of EMAC model outputs with existing populations of Ae. albopictus in Europe as described in Waldock et al. . The seven empirical criteria used to define a suitable, in terms of climate conditions, environment for the Asian tiger mosquito using EMAC model outputs are Thank you for your interest in spreading the word on Philosophical Transactions of the Royal Society B: Biological Sciences.
