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

description: 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 into newly suitable areas, many expansions appear to be
 filling preexisting thermally suitable habitats. Our findings highlight
 the need for long-term mosquito monitoring, rigorous climate-attribution
 methods, and better documentation of confounding factors like land-use
 change and vector control efforts to disentangle climate-driven changes
 from other anthropogenic factors.

 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 compared, if
 stated. ### Files and variables #### File: Mosquito_range_review_code.R
