Does sea level rise affect the Puritan tiger beetle?
We are uncertain how sea level rise has affected Puritan tiger beetles. Sea level rise may increase the rate of cliff erosion and may also result in narrower beaches. A moderate increase in the rate of cliff erosion is likely to improve the cliff habitat for larval tiger beetles. Further narrowing of beaches is likely to decrease the value of the beach habitat for adult tiger beetles. The net effect on populations of the Puritan tiger beetle is therefore difficult to predict.
