Variation in body size and sexual size dimorphism in the most widely ranging lizard: testing the effects of reproductive mode and climate
Reproductive mode, ancestry, and climate are hypothesized to determine body size variation in reptiles but their effects have rarely been estimated simultaneously, especially at the intraspecific level. The common lizard (Zootoca vivipara) occupies almost the entire Northern Eurasia and includes viv...

| description | Reproductive mode, ancestry, and climate are hypothesized to determine body size variation in reptiles but their effects have rarely been estimated simultaneously, especially at the intraspecific level. The common lizard (Zootoca vivipara) occupies almost the entire Northern Eurasia and includes viviparous and oviparous lineages, thus representing an excellent model for such studies. Using body length data for >10,000 individuals from 72 geographically distinct populations over the species' range, we analyzed how sex‐specific adult body size and sexual size dimorphism (SSD) is associated with reproductive mode, lineage identity, and several climatic variables. Variation in male size was low and poorly explained by our predictors. In contrast, female size and SSD varied considerably, demonstrating significant effects of reproductive mode and particularly seasonality. Populations of the western oviparous lineage (northern Spain, south‐western France) exhibited a smaller female size and less female‐biased SSD than those of the western viviparous (France to Eastern Europe) and the eastern viviparous (Eastern Europe to Far East) lineages; this pattern persisted even after controlling for climatic effects. The phenotypic response to seasonality was complex: across the lineages, as well as within the eastern viviparous lineage, female size and SSD increase with increasing seasonality, whereas the western viviparous lineage followed the opposing trends. Altogether, viviparous populations seem to follow a saw‐tooth geographic cline, which might reflect the nonmonotonic relationship of body size at maturity in females with the length of activity season. This relationship is predicted to arise in perennial ectotherms as a response to environmental constraints caused by seasonality of growth and reproduction. The SSD allometry followed the converse of Rensch's rule, a rare pattern for amniotes. Our results provide the first evidence of opposing body size—climate relationships in intraspecific units.
We analyzed the association of adult body size and sexual size dimorphism (SSD) with reproductive mode (viviparity vs. oviparity), lineage identity, and climate in the common lizard (Zootoca vivipara), the species occupying almost entire Northern Eurasia. We revealed a moderate effect of reproductive mode (larger female size and higher SSD in viviparous vs. oviparous populations) and a strong but complex effect of seasonality: female size and SSD decrease with increasing s |

mode, ancestry, and climate are hypothesized to determine body size variation in reptiles but their effects have rarely been estimated simultaneously, especially at the intraspecific level. The common lizard (Zootoca vivipara) occupies almost the entire Northern Eurasia and includes viviparous and oviparous lineages, thus representing an excellent model for such studies. Using body length data for >10,000 individuals from 72 geographically distinct populations over the species' range, we analyzed how sex‐specific adult body size and sexual size dimorphism (SSD) is associated with reproductive mode, lineage identity, and several climatic variables. Variation in male size was low and poorly explained by our predictors. In contrast, female size and SSD varied considerably, demonstrating significant effects of reproductive mode and particularly seasonality. Populations of the western oviparous lineage (northern Spain, south‐western France) exhibited a smaller female size and less female‐biased SSD than those of the western viviparous (France to Eastern Europe) and the eastern viviparous (Eastern Europe to Far East) lineages; this pattern persisted even after controlling for climatic effects. The phenotypic response to seasonality was complex: across the lineages, as well as within the eastern viviparous lineage, female size and SSD increase with increasing seasonality, whereas the western viviparous lineage followed the opposing trends. Altogether, viviparous populations seem to follow a saw‐tooth geographic cline, which might reflect the nonmonotonic relationship of body size at maturity in females with the length of activity season. This relationship is predicted to arise in perennial ectotherms as a response to environmental constraints caused by seasonality of growth and reproduction. The SSD allometry followed the converse of Rensch's rule, a rare pattern for amniotes. Our results provide the first evidence of opposing body size—climate relationships in intraspecific units.
We analyzed the association of adult body size and sexual size dimorphism (SSD) with reproductive mode (viviparity vs. oviparity), lineage identity, and climate in the common lizard (Zootoca vivipara), the species occupying almost entire Northern Eurasia. We revealed a moderate effect of reproductive mode (larger female size and higher SSD in viviparous vs. oviparous populations) and a strong but complex effect of seasonality: female size and SSD decrease with increasing seasonality in the Western viviparous lineage distributed from France to Eastern Europe, while the Eastern viviparous lineage ranging from Eastern Europe to the Far East showed the opposite trends. Our results provide the first evidence of opposing body size—climate relationships in clearly intraspecific units.</abstract><cop>HOBOKEN</cop><pub>Wiley</pub><pmid>32551042</pmid><doi>10.1002/ece3.6077</doi><orcidid>https://orcid.org/0000-0002-3515-729X</orcidid><orcidid>https://orcid.org/0000-0003-0621-9049</orcidid><orcidid>https://orcid.org/0000-0002-0249-4695</orcidid><orcidid>https://orcid.org/0000-0001-5228-9940</orcidid><orcidid>https://orcid.org/0000-0003-1952-9310</orcidid><orcidid>https://orcid.org/0000-0003-4613-5237</orcidid><orcidid>https://orcid.org/0000-0002-3000-6476</orcidid><orcidid>https://orcid.org/0000-0003-4389-2355</orcidid><oa>free_for_read</oa></addata></record> |
