Bee richness and abundance In our study, as expected, bee species richness showed a significant trend to decrease with increasing elevation, which is in agreement with previous literature describing a pattern commonly observed in insects in general, with either a mid-elevation peak or a monotonical decrease in species diversity over the entire elevational gradient [ 34 , 35 , 37 , 38 , 50 ].

The sentences
(Caution: see plots in the word document attached "Response to Reviewers") These three trends combined could, effectively, determine the lack of a clear trend in the global analysis ‘Bee abundance vs Elevation’.
Our results suggest that temperature is restrictive enough in our elevational gradient to negatively affect bee richness, resulting in a decreasing trend of bee richness with increasing elevations (and lower temperatures).
