Late bloomers and baby boomers: ecological drivers of longevity in squamates and the tuatara (2015, background): “A number of interspecific studies of birds and mammals have observed prolonged longevity with increasing body size (e.g. Lindstedt & Calder, 1976, 1981; Wilkinson & South, 2002; Speakman, 2005a; Healy et al., 2014; Valcu et al., 2014).”
Modeling environmental effects on the size-structured energy flow through marine ecosystems. Part 1: The model (2007, background): “4 Temperature effect on physiological rates Due to its major importance in controlling chemical reactions, temperature strongly influences metabolic rates of living organisms (Clarke et al., 1999; Kooijman, 2000; Pörtner, 2002; Clarke, 2004; Speakman, 2005).”
The evolution of senescence from a comparative perspective (2008, background): “Because both metabolic rate and initial mortality rate tend to decrease with increasing body mass (Speakman 2005), it is important to design comparisons that separate these influences statistically.”
Trends in oxidative aging theories. (2007, background): “Although the rate-of-living hypothesis is no longer accepted [2,4,5], it directed the attention of aging research onto oxygen metabolism.”
Reconsidering the mechanistic basis of the metabolic theory of ecology (2007, background): “Life history-size covariation Kozlowski and Weiner 1997, Kozlowski 2000, Speakman 2005 selection on life history phenotype modifies allometries theoretical requires pre-existing allometries restrictive assumptions Quantum statistics Demetrius 2003 constraints on oxidative electron transport/ATP…”
Remarkable insights into the paleoecology of the Avalonian Ediacaran macrobiota (2015, neutral): “Whereas size is a sensible indicator of age formost marine organisms (Speakman, 2005), it is important to bear in mind that this correlation has yet to be proven for Ediacaran species.”
Caloric restriction. (2011, methodology): “Direct measurements of RMR in mice under 20% restriction suggest that reduced RMR contributes about 24% to the overall energy savings (Hambly and Speakman, 2005), the balance being predominantly made up by reduced physical activity levels.”
An integrative study of ageing in a wild population of common lizards (2011, background): “Among the few studies investigating ageing variation of metabolic rate, decline with age and lack of age variation are the most frequent observations (Speakman 2005; Moe et al. 2009).”
Life and death: metabolic rate, membrane composition, and life span of animals. (2007, background): “When lifetime mass-specific FMR was calculated for 49 mammal species (all weighing 4 kg), there was a statistically highly significant negative relationship with species body mass, which is also contrary to the rate-of-living prediction of a relatively constant lifetime energy turnover per gram of a”
