Summary of previous research testing for an effect of genome size on metabolic rate.

authors (year)	taxa	method	result	reference
Vinogradov (1995)	birds and mammals	multiple regression of extracted residuals	negative effect in mammals but not in birds	[4]
Smith et al. (2017)	bats	simple regression of extracted residuals independent contrasts not used for BMR correlations	evidence for negative effect only at species level w/o mass correction no evidence otherwise	[10]
Vinogradov (1997)	birds	phylogenetic independent contrasts (PIC) of extracted residuals	negative effect	[5]
Gregory (2002)	birds	simple regression of extracted residuals	negative effect	[6]
Waltari & Edwards (2002)	vertebrates	PIC	no effect globally but negative for amniotes and archosaurs	[7]
Kozłowski et al. (2003)	birds and mammals	simple regression of genome size and BMR slope coefficients	negative effect	[11]
Uyeda et al. (2017)	vertebrates	multiple regression using a phylogenetic Ornstein-Uhlenbeck model	genome size effect not included in final model	[9]
Ji & DeWoody (2017)	birds	PIC	no effect	[8]
Licht & Lowcock (1991)	urodeles	simple regression at different temperatures	slight negative effect only at 25°C	[12]
Gregory (2003)	lissamphibians	simple regression of extracted residuals	negative overall but not within anurans and urodeles	[13]
Hardie & Herbert (2004)	actinopterygians	simple regression	no effect at the family level	[14]
Smith & Gregory (2009)	actinopterygians	simple regression of extracted residuals	no effect	[15]
