The negative effect of climate change on plants and plant–pollinator interactions is a matter of concern worldwide. The Mediterranean region is considered particularly susceptible to climate warming and the communities of this region will need to face considerable climatic changes over the 21st century. In a new study published in AoB PLANTS, Takkis et al. examined the effect of temperature on nectar secretion of two Mediterranean species (Ballota acetabulosa and Teucrium divaricatum) to evaluate their potential responses to climate change and the consequent effect on their pollinators. Their results indicated that both species would handle moderate warming relatively well but would be negatively affected by the strong warming predicted for the end of this century.
