“…In the isopod Ceratoserolis trilobitoides, eggs almost doubled in size with a less than 15° increase in latitude, where egg dry mass ranged from 3.3 to 3.9 mg dry mass in sub-Antarctic South Georgia to 6.5 mg dry mass in the high Weddell Sea (Wägele 1987. Within species, trends to larger egg size at higher latitude in Antarctica have also been demonstrated in the philobryid bivalves Lissarca miliaris (Reed et al 2014) and Lissarca notorcadensis , the caridean decapod Notocrangon antarcticus (Lovrich et al 2005) and in some nototheniid fish (Kock & Kellerman 1991).…”

“…The corollary of large egg size is smaller numbers of eggs released at each spawning event, and there are data that support this contention. Reports on this topic include studies on fish (La Mesa et al 2008), mysid shrimps (Siegel & Mühlenhardt-Siegel 1988), gastropod and bivalve molluscs (Simpson 1977, Reed et al 2014, nudibranch molluscs (Wägele 1988, Woods & Moran 2008, and caridean shrimps (Gorny et al 1992, Clarke 1993a, Arntz et al 1994. As larger eggs are generally correlated with fewer eggs produced in Antarctic species, a related question then emerges around how much energy and other resources are invested in reproduction and how high latitude species compare with those in temperate or tropical regions.…”

Animals living in the Southern Ocean have evolved in a singular environment. It shares many of its attributes with the high Arctic, namely low, stable temperatures, the pervading effect of ice in its many forms and extreme seasonality of light and phytobiont productivity. Antarctica is, however, the most isolated continent on Earth and is the only one that lacks a continental shelf connection with another continent. This isolation, along with the many millions of years that these conditions have existed, has produced a fauna that is both diverse, with around 17,000 marine invertebrate species living there, and has the highest proportions of endemic species of any continent. The reasons for this are discussed. The isolation, history and unusual environmental conditions have resulted in the fauna producing a range and scale of adaptations to low temperature and seasonality that are unique. The best known such adaptations include channichthyid icefish that lack haemoglobin and transport oxygen around their bodies only in solution, or the absence, in some species, of what was only 20 years ago termed the universal heat shock response. Other adaptations include large size in some groups, a tendency to produce larger eggs than species at lower latitudes and very long gametogenic cycles, with egg development (vitellogenesis) taking 18-24 months in some species. The rates at which some cellular and physiological processes are conducted appear adapted to, or at least partially compensated for, low temperature such as microtubule assembly in cells, whereas other processes such as locomotion and metabolic rate are not compensated, and whole-animal growth, embryonic development, and limb regeneration in echinoderms proceed at rates even slower than would be predicted by the normal rules governing the effect of temperature on biological processes. This review describes the current state of knowledge on the biodiversity of the Southern Ocean fauna and on the majority of known ecophysiological adaptations of coldblooded marine species to Antarctic conditions. It further evaluates the impacts these adaptations have on capacities to resist, or respond to change in the environment, where resistance to raised temperatures seems poor, whereas exposure to acidified conditions to end-century levels has comparatively little impact.

“…Measuring physiological variation across large spatial scales provides a definitive means to understand species‐specific physiological responses to a dynamic environment, but is logistically challenging and not commonly achieved in aquatic systems (Osovitz & Hofmann, 2007). A pragmatic alternative is to use growth rates in natural populations (Reed et al., 2014) and, as growth is a trade‐off with metabolic rates and reproduction, it represents a reasonable approximation of whole animal physiology (Clarke, 2003; Pörtner et al., 2001). Here, we use overall growth performance (OGP, the point of inflection in a von Bertalanffy growth curve; Brey, 1999) in marine bivalves to quantify growth constraints between biogeographical realms.…”

Aim Growth rates of organisms are routinely used to summarize physiological performance, but the consequences of local evolutionary history and ecology are largely missed by analyses on wide biogeographical scales. This broad approach has been commonly applied to other physiological parameters across terrestrial and aquatic environments. Here, we examine growth rates of marine bivalves across all biogeographical realms, latitude, and temperature, with analyses to determine regional effects on growth on global scales. Location Global: marine ecosystems. Time period 1930–2018. Major taxa Bivalves. Methods We use a comprehensive data set of bivalve growth parameters (n = 966, 243 species) representing all biogeographical realms to calculate overall growth performances. We use these data with environmental temperature to analyse global patterns in growth, accounting for regional primary productivity and phylogeny using general additive mixed and linear models. The Arrhenius relationship and corresponding activation energies are used to quantify the sensitivity to temperature in each biogeographical realm and province. Results Our analyses show that bivalve growth demonstrates latitudinal asymmetry and exhibits nonlinear relationships with latitude. We find that overall growth performance is affected by temperature and particulate organic carbon, but the form of these relationships differs with phylogeny. Growth is slower and more sensitive to increasing temperature in the Antarctic than it is in the Arctic, and decreases with increasing temperature in some tropical realms, a previously unidentified and fundamental difference in growth and physiological sensitivity. Main conclusions Our findings provide compelling evidence that the widely used curvilinear relationship between temperature and growth rates in marine ectotherms is an inappropriate descriptor of thermal sensitivity, because it normalizes regional variations in physiological performance. Without a more detailed assessment of global physiological patterns, the responses of species to local variations associated with climate change will be under‐appreciated in global assessments of climate risk, minimizing the effectiveness of management and conservation.

“…There is a broad understanding of which species are most vulnerable to climate change (e.g., Kroeker et al, 2013;Peck, 2016;Wassmann et al, 2011) and how species may respond through migration or plasticity (Frainer et al, 2017;Thyrring et al, 2015). However, the survival of populations is not solely dependent on the tolerance of individuals to change, but also on the ability to reproduce and recruit to the environment (Przeslawski et al, 2015), without significant trade-offs with growth or fecundity (Reed et al, 2014).…”

“…Indeed, the vast array of development modes and gametogenic responses to the environment make it impossible to project the influence of change on species-specific life history without direct observation (Marshall et al, 2012). While there have been numerous studies on reproductive trait variability across wide latitudinal ranges, local variability is often ignored (Lester et al, 2007;Reed et al, 2014). However, evidence of species resilience through plasticity to regional and subtle environmental variations could still provide essential information to understanding the future distribution of benthic macrofauna (Byrne, 2011) and the maintenance of ecosystem functioning (Gogina et al, 2020;McLean et al, 2018).…”
