Dataset used in the paper "Temperature dissimilarity drives flower-visitor interaction turnover across elevation in the Mexican Transition Zone" accepted for publication in Journal of Biogeography

We established 10 sampling sites separated by ~200–500 m in elevation on the eastern slope of Cofre de Perote, spanning an elevational gradient from 4 to 3,425 m.a.s.l. Cofre de Perote is an extant volcano in the eastern part of the MTZ (between 19° 25’ 5.7” and 19° 36’ 54” N, and 94 ̊ 44’ 43.5” and 97 ̊ 09’ 36.9” W), right at the confluence of the volcanic transversal belt and the Sierra Madre Oriental. Cofre de Perote has an elevation of 4,282 m and its geological origin dates back to the Miocene (~20 million years ago, Figure 1). Our sampling sites were located in the Jamapa River basin, which encompasses the eastern slope of Cofre de Perote. Each of the sampling sites displayed different types of vegetation and were classified as coastal dunes (4–30 m elevation; temperature when the sampling was carried out ranging from 32 to 36 °C), dry deciduous forest (30–1,000 m; 23–31 °C), cloudy mountain forest (1,500–2,500 m; 19–20 °C), pine-oak forest (3,000 m; 10–16 °C), or fir forest (3,500 m; 7–13 °C); the tree line is located at approximately 3,700 m of elevation. We are providing interaction networks involving interactions between plants and their floral visitors for each elevation studied (n= 10). In addition, we are providing a general metadata with the information of each site where collections were performed.
