“…It is well known that captive environments could have larger effects than genotype in salmonids (Chittenden et al, 2010 ). A previous study reported no difference in metabolic rates of wooly sculpin ( Clinocottus analis ) between northern and southern populations and discussed that the lack of difference could be attributed to fish becoming acclimated to the captive rearing environment (Rangel & Johnson, 2019 ). Thus, it is possible that captive rearing environments rather than natural environments during early life stages could have greatly negated the population effects on phenotypic development and affected the results (Burggren, 2020 ).…”

Environmental temperatures differ across latitudes in the temperate zone, with relatively lower summer and fall temperatures in the north leading to a shorter growing season prior to winter. As an adaptive response, during early life stages, fish in northern latitudes may grow faster than their conspecifics in southern latitudes, which potentially manifests as different allometric relationships between body mass and metabolic rate. In the present study, we examined if population or year class had an effect on the variation of metabolic rate and metabolic scaling of age‐0 lake sturgeon (Acipenser fulvescens) by examining these traits in both a northern (Nelson River) and a southern (Winnipeg River) population. We compiled 6 years of data that used intermittent flow respirometry to measure metabolic rate within the first year of life for developing sturgeon that were raised in the same environment at 16°C. We then used a Bayesian modeling approach to examine the impacts of population and year class on metabolic rate and mass‐scaling of metabolic rate. Despite previous reports of genetic differences between populations, our results showed that there were no significant differences in standard metabolic rate, routine metabolic rate, maximum metabolic rate, and metabolic scaling between the two geographically separated populations at a temperature of 16°C. Our analysis implied that the lack of metabolic differences between populations could be due to family effects/parental contribution, or the rearing temperature used in the study. The present research provided insights for conservation and reintroduction strategies for these populations of lake sturgeon, which are endangered or threatened across most of their natural range.

“…The effects of temperature exposure on thermal sensitivity of metabolic rates have been particularly well studied across large spatial scales (Steffensen et al 1994; Irlich et al 2009). For example, for Woolly Sculpins (Clinocottus analis), southern populations on the California coast experience warmer conditions and have greater individual variation in metabolic rates compared to more northern populations exposed to colder temperatures (Rangel and Johnson 2019).…”

As climate change continues, anticipating species' responses to rising temperatures, requires an understanding of the relationship between metabolic rate and thermal sensitivity, which itself may vary over space and time. We measured metabolic rates of three representative marine invertebrate species (hermit crabs Pagurus hirsutiusculus, periwinkle snails Littorina sitkana, and mussels Mytilus trossulus) and evaluated the relationship between thermal sensitivity (Q 10 ) and thermal history. We tested the hypothesis that thermal history drives thermal sensitivity and quanti ed how this relationship differs over time (short-term to seasonal time scales) and between species. Organisms were collected from tide pools in Sitka, Alaska where we also recorded temperatures to characterize thermal history prior to metabolic rate assays. Using respirometry, we estimated mass-speci c oxygen consumption (MO 2 ) at ambient and increased temperatures for one individual per species per tide pool across three seasons. We evaluated relationships between thermal sensitivity and pool temperatures for time periods ranging from 1 day to 3 months prior to collection. For all species, thermal sensitivity was related to thermal history for the shorter time periods (1 day to 1 week). However, the direction of the relationships and most important thermal parameters (i.e., maximum, mean, or range) differed between species and seasons. We found that on average, P. hirsutiusculus and L. sitkana were more thermally sensitive than M. trossulus. These ndings show that variability in thermal history over small spatial scales in uences individuals' metabolic response to warming and may be indicative of these species' ability to acclimate to future climate change.
