... ). In addition, basal metabolic rates (BMRs) are positively correlated to reproduction, such that species with high BMRs often have higher reproductive rates ( Hennemann, 1983 ). Therefore, at the interspecific level, variation in metabolic rates may mediate important tradeoffs between reproduction and survival...
