Table 3 The total traits considered in the analyses with an indication of their expected functional meaning and the number of Gower distance groups113.
Trait | Trait type | Expected functional meaning | Bibliography | Gower group |
|---|---|---|---|---|
Body size | Biological [Continuous] | Body size is tightly linked to temperature. Body size of assemblages of odonates is mainly driven by temperature. | Group 1 | |
Abdomen length | Biological [Continuous] | As for body size. | Group 1 | |
Wings length | Biological [Continuous] | Proxy for dispersal. | Group 1 | |
Habitat | Ecological [Categorical] | Freshwater habitats (lentic/lotic) are among the most threatened ecosystems by climate change. | Group 2 | |
Flight season time | Ecological [Continuous] | Indirect measure of dispersal potential. | Group 3 | |
Abdomen pigmentation | Biological [Continuous] | Pigmentation and colour patterns are directly related with thermoregulatory mechanisms. For example, melanism is linked to greater absorption of solar radiation heat in cooler regions. | Group 4 |
