TL;DR: In this article, the authors analyzed the relationship between environmental predictors and the geographical distribution of species richness, body size, range size and abundance in 97 multi-factorial data sets and concluded that the ecological importance of regression coefficients cannot be evaluated with confidence irrespective of whether spatially explicit or non-spatial modeling is used.

TL;DR: The results support the heat balance hypothesis, suggesting that the thermoregulatory abilities of anurans would allow them to reach larger sizes in colder climates by optimizing the trade-off between heating and cooling rates, whereas a lack of such strategies among urodele faunas would explain why these organisms tend to be smaller in cooler areas.

TL;DR: In this paper, the authors investigated the relationship between body size patterns and environmental gradients in European and North American squamate reptile assemblages and found that although body size influences the energy balance of thermoregulating ectotherms, inconsistent biogeographical patterns and contrasting associations with energy in lizards and snakes suggest that no single mechanism can explain variation of reptile body size in the northern temperate zone.

TL;DR: The results suggest that fundamentally different patterns of thermal limits found among the earth's realms may be largely explained by differences in episodic thermal extremes among realms, updating global macrophysiological ‘rules’.

TL;DR: The analyses suggest that both local and broad-scale patterns of mammal body size variation are influenced in part by the strong mesoscale climatic gradients existing in mountainous areas.
