“…Empirically derived relationships between temperature and metabolism-linked variables have been used widely to estimate long-term responses of ecosystems to warming in the absence of long-term metabolism data (Cheung et al, 2008;Daufresne et al, 2009;Dillon et al, 2010;Gardner et al, 2011;Marotta et al, 2014;Weber et al, 2015). These estimations suggest that linear warming will increase metabolic rates exponentially, with consequences for all levels of biological organization from individuals to ecosystems.…”

Climate warming is expected to have large effects on ecosystems in part due to the temperature dependence of metabolism. The responses of metabolic rates to climate warming may be greatest in the tropics and at low elevations because mean temperatures are warmer there and metabolic rates respond exponentially to temperature (with exponents >1). However, if warming rates are sufficiently fast in higher latitude/elevation lakes, metabolic rate responses to warming may still be greater there even though metabolic rates respond exponentially to temperature. Thus, a wide range of global patterns in the magnitude of metabolic rate responses to warming could emerge depending on global patterns of temperature and warming rates. Here we use the Boltzmann-Arrhenius equation, published estimates of activation energy, and time series of temperature from 271 lakes to estimate long-term (1970-2010) changes in 64 metabolic processes in lakes. The estimated responses of metabolic processes to warming were usually greatest in tropical/low-elevation lakes even though surface temperatures in higher latitude/elevation lakes are warming faster. However, when the thermal sensitivity of a metabolic process is especially weak, higher latitude/elevation lakes had larger responses to warming in parallel with warming rates. Our results show that the sensitivity of a given response to temperature (as described by its activation energy) provides a simple heuristic for predicting whether tropical/low-elevation lakes will have larger or smaller metabolic responses to warming than higher latitude/elevation lakes. Overall, we conclude that the direct metabolic consequences of lake warming are likely to be felt most strongly at low latitudes and low elevations where metabolism-linked ecosystem services may be most affected.

“…In North America, however, estimated ages up to 27 years (but no corresponding L t data) were recently provided for some populations of C . carpio (Weber et al ., , ) and individuals older than 30 years also have been reported (Bajer & Sorensen, ; Bajer et al ., ). Finally, the L t graph in Rypel's () Figure 2 plotting (invasive) C .…”

“…This was contrary to recent findings for C . carpio in North America, where populations sampled consistently over a latitudinal gradient had lower growth rates at higher latitudes, but achieved larger maximum size and lower mortality rates than populations at lower latitudes (Weber et al ., ). Similarly, based on 14 stocks worldwide (both native and non‐native), Fernández‐Delgado () identified two clusters of slow and fast‐growing populations and found a significant decrease in growth rate with increasing latitude.…”

This review provides a meta-analytical assessment of the global patterns and clines in the growth of Cyprinus carpio as measured by length-at-age (L ) or von Bertalanffy growth function (VBGF) parameters, mass-length relationship (W-L ) and condition factor, based on literature data. In total, 284 studies were retrieved spanning 91 years of research and carried out on 381 waterbodies-locations in 50 countries in all five continents. Although native C. carpio achieved larger (asymptotic) size relative to its non-native counterpart, the latter grew faster during the first 7 years of life. Lentic populations (especially in natural lakes) also achieved larger sizes relative to lotic ones and the same was true for populations in cold and temperate v. arid climates. Unlike previous studies (on much more restricted datasets), only weak latitudinal clines in instantaneous growth rate, L at age 3 and mortality were observed globally and this was probably due to the presence of counter-gradient growth variation at all representative age classes (i.e. 1-10 years). Slightly negative allometry was revealed by the W-L and the related form factor tended to distinguish the more elongated and torpedo-shaped body typical of the wild form from the deeper body of feral-domesticated C. carpio. Existing population dynamics models for C. carpio will benefit from the comprehensive range of waterbody type × climate class-specific VBGF parameters provided in the present study; whereas, more studies are needed on the species' growth in tropical regions and to unravel the possibility of confounding effects on age estimation due to both historical and methodological reasons.

“…As temperature increased markedly between the early 1990s and mid-2000s, the decline in growth that occurred in the intervening period runs counter to the relationship recorded between growth and temperature for many fish species and is not consistent with the metabolic theory of ecology (Brown et al, 2004;Weber et al, 2015). Thus, any potential positive relationship between growth and temperature was over-ridden by hypoxia and related effects, such as increased density (see above).…”

Factors influencing growth of Acanthopagrus butcheri (Sparidae) in a eutrophic estuary have changed over time

The overall growth of Acanthopagrus butcheri in the eutrophic Swan River Estuary has previously been shown to decline between 1993-95 and 2007-11. This was attributed to the effects of an increase in hypoxia on A. butcheri in deeper water, brought about by reductions in freshwater flushing, and to density-dependent effects as this species became concentrated in the better-oxygenated, nearshore shallow waters. In the present study, a year-effect model was developed that provided a good fit to the lengths at age and could thus be used to explore the following: 1) The extent to which somatic growth of A. butcheri differed between years in the above two periods and within the later period, which was extended to include data for 2012 to 2014, and 2) whether annual growth in 2007-14 was related to temperature and/or freshwater discharge. Annual length increments for females and males during the second year of life, predicted from the model using a common initial length, were almost invariably less in each year in 2007-14 than in 1993-95. In 2007-14, these predicted increments varied by ~2 times for both females and males and were positively correlated with average temperature during the main growth phase of A. butcheri. They were not significantly correlated, however, with freshwater discharge in the preceding cool wet 'winter' months, when the vast majority of rainfall occurs.The demonstration that the growth of A. butcheri was positively correlated with temperature for years in the latter period is consistent with the metabolic theory of ecology and contrasts with M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT2 growth declining between 1993-95 and 2007-14 when temperatures were increasing. Thus, any influence of temperature on growth between those periods was overridden by other factors, i.e. hypoxia and increased densities. As A. butcheri completes its life cycle within its natal estuary and has plastic biological characteristics, it is an ideal candidate for use as an indicator of the health of an estuary and for hypothesising on the effects of climate change on fish species.
