A scoping review of mosquito vector range shifts: widespread expansions and evidence gaps in climate attribution

As global temperatures rise, concerns about shifting mosquito ranges—and accompanying changes in the transmission of malaria, dengue, and other diseases—are mounting. However, systematic evidence for climate-driven changes in mosquito ranges remains limited. We conducted a scoping review following PRISMA-ScR guidelines of studies documenting expansions or contractions in medically important mosquito species. In total, 178 studies on six continents identified range expansions in 118 mosquito species. While over a third of these studies cited warming as a driver, fewer than 10% performed statistical tests of the role of climate. Instead, most expansions were linked to human-aided dispersal (e.g., trade, travel), land-use changes, and urbanization. Although several studies reported poleward or upward expansions consistent with climate warming, none demonstrated warm-edge contractions driven by rising temperatures, which are theoretically predicted in some settings. Rather than expanding in..., , # Data from: A scoping review of mosquito vector range shifts: widespread expansions and evidence gaps in climate attribution

## Description of the data and file structure

We conducted a scoping review of studies related to changes in mosquito ranges. Exact search string and criteria can be found in the paper methods. Reviewers extracted the following information from the studies that met the inclusion criteria (n = 178): species name(s); study geographic location(s), with latitude and longitude points if available; study date(s); reference period date(s); vector collection methods; whether the study reports a range expansion, contraction, or both; distance or velocity of range movement; a narrative summary of the asserted causes of the range shift; a summary of the evidence used in attributing the causes. The reference period is defined as the historical period to which the species range is being compare...,
