“…This suggests that the hypothesized link between SMR and MMR (i.e., that a significant component of minimum metabolic rate is the cost of maintaining the machinery needed to sustain MMR; Bennett and Ruben 1979;Biro and Stamps 2010) is perhaps too simplistic when examining variability among individuals kept under the same conditions. The processes driving the two components of AS thus appear distinct.…”

“…However, while a positive correlation between minimum and maximum metabolic rates at the intraspecific level has indeed been found in some contexts Biro and Stamps 2010;Careau et al 2014aCareau et al , 2014b, this is not the case in others (Chappell et al 2004(Chappell et al , 2007Gomes et al 2004;Careau et al 2014b). The mechanisms underlying this purported link are also equivocal, with some studies reporting a positive relationship between metabolic rates and underlying traits such as organ size (Konarzewski and Ksiazek 2013) or mitochondrial density (Norin and Malte 2012), whereas others find no relationship (Selman et al 2001;Chappell et al 2007;Larsen et al 2011;Norin and Malte 2012;Boldsen et al 2013).…”

“…Minimum and maximum metabolic rates are predicted to be positively correlated with one another since SMR or BMR is thought to reflect the maintenance costs of the metabolic machinery needed to support MMR capacity (Bennett and Ruben 1979;Biro and Stamps 2010).

Standard metabolic rate (SMR) and maximum metabolic rate (MMR) typically vary two-or threefold among conspecifics, with both traits assumed to significantly impact fitness. However, the underlying mechanisms that determine such intraspecific variation are not well understood. We examined the influence of mitochondrial properties on intraspecific variation in SMR and MMR and hypothesized that if SMR supports the cost of maintaining the metabolic machinery required for MMR, then the mitochondrial properties underlying these traits should be shared. Mitochondrial respiratory capacity (leak and phosphorylating respiration) and mitochondrial content (cytochrome c oxidase activity) were determined in the liver and white muscle of brown trout Salmo trutta of similar age and maintenance conditions. SMR and MMR were uncorrelated across individuals and were not associated with the same mitochondrial properties, suggesting that they are under the control of separate physiological processes. Moreover, tissue-specific relationships between mitochondrial properties and whole-organism metabolic traits were observed. Specifically, SMR was positively associated with leak respiration in liver mitochondria, while MMR was positively associated with muscle mitochondrial leak respiration and mitochondrial content. These results suggest that a high SMR or MMR, rather than signaling a higher ability for respiration-driven ATP synthesis, may actually reflect greater dissipation of energy, driven by proton leak across the mitochondrial inner membrane. Knowledge of these links should aid interpretation of the potential fitness consequences of such variation in metabolism, given the importance of mitochondria in the utilization of resources and their allocation to performance.

“…Perhaps then, the traits measured here do not directly affect risk exposure and IIV covaries other unmeasured traits, in addition to mass. Although haemocyanin concentration is indicative of high performance, we did not measure metabolic rate directly and IIV might covary with metabolic rate, because high activity rates are expected to correlate with risk exposure [22,26,28]. Another possibility is that IIV variation might reflect among-individual differences in ability to accurately perceive risk levels [4].…”

Individual quality and personality: bolder males are less fecund in the hermit crabPagurus bernhardus

One explanation for animal personality is that different behavioural types derive from different life-history strategies. Highly productive individuals, with high growth rates and high fecundity, are assumed to live life at a fast pace showing high levels of boldness and risk taking, compared with less productive individuals. Here, we investigate among-individual differences in mean boldness (the inverse of the latency to recover from a startling stimulus) and in the consistency of boldness, in male hermit crabs in relation to two aspects of life-history investment. We assessed aerobic scope by measuring the concentration of the respiratory pigment haemocyanin, and we assessed fecundity by measuring spermatophore size. First, we found that individuals investing in large spermatophores also had high concentrations of haemocyanin. Using doubly hierarchical-generalized linear models to analyse longitudinal data on startle responses, we show that hermit crabs vary both in their mean response durations and in the consistency of their behaviour. Individual consistency was unrelated to haemocyanin concentration or spermatophore size, but mean startle response duration increased with spermatophore size. Thus, counter to expectations, it was the most risk-averse individuals, rather than the boldest and most risk prone, that were the most productive. We suggest that similar patterns should be present in other species, if the most productive individuals avoid risky behaviour.

“…Likewise, we detected no differences in prolonged swimming performance among low‐plated freshwater fish and their full‐plated marine conspecifics. These discrepancies may be explained by an association between prolonged swimming performance and fitness in environments characterized by low‐predation pressures and high intraspecific competition, where success in searching for food could be the main factor for survival and reproduction (Biro & Stamps, 2010). Although this description is highly congruous with the ecology of Karilampi, we detected no direct signatures of selection on U crit .…”

Conspecifics inhabiting divergent environments frequently differ in morphology, physiology, and performance, but the interrelationships amongst traits and with Darwinian fitness remains poorly understood. We investigated population differentiation in morphology, metabolic rate, and swimming performance in three‐spined sticklebacks (Gasterosteus aculeatus L.), contrasting a marine/ancestral population with two distinct freshwater morphotypes derived from it: the “typical” low‐plated morph, and a unique “small‐plated” morph. We test the hypothesis that similar to plate loss in other freshwater populations, reduction in lateral plate size also evolved in response to selection. Additionally, we test how morphology, physiology, and performance have evolved in concert as a response to differences in selection between marine and freshwater environments. We raised pure‐bred second‐generation fish originating from three populations and quantified their lateral plate coverage, burst‐ and critical swimming speeds, as well as standard and active metabolic rates. Using a multivariate Q ST‐F ST framework, we detected signals of directional selection on metabolic physiology and lateral plate coverage, notably demonstrating that selection is responsible for the reduction in lateral plate coverage in a small‐plated stickleback population. We also uncovered signals of multivariate selection amongst all bivariate trait combinations except the two metrics of swimming performance. Divergence between the freshwater and marine populations exceeded neutral expectation in morphology and in most physiological and performance traits, indicating that adaptation to freshwater habitats has occurred, but through different combinations of traits in different populations. These results highlight both the complex interplay between morphology, physiology and performance in local adaptation, and a framework for their investigation.
