“…For example, shifts in spatial distribution may preclude the necessity for phenological adjustments in a given species attempting to maintain its thermal niche. Other adaptation strategies involve species plasticity and genetic modification in order to face changing conditions (Lavergne et al, 2010;Dam, 2013), which have been documented for spatially isolated zooplankton (Peijnenburg et al, 2006;Yebra et al, 2011), but could not be confirmed for other species (Provan et al, 2009). Another alternative adaptation strategy is the change in depth-distribution, i.e., the migration to deeper waters in search for cooler temperatures carried out by fishes (Perry et al, 2005).…”

With global climate change altering marine ecosystems, research on plankton ecology is likely to navigate uncharted seas. Yet, a staggering wealth of new plankton observations, integrated with recent advances in marine ecosystem modeling, may shed light on marine ecosystem structure and functioning. A EuroMarine foresight workshop on the "Impact of climate change on the distribution of plankton functional and phylogenetic diversity" (PlankDiv) identified five grand challenges for future plankton diversity and macroecology research: (1) What can we learn about plankton communities from the new wealth of high-throughput "omics" data? (2) What is the link between plankton diversity and ecosystem function? (3) How can species distribution models be adapted to represent plankton biogeography? (4) How will plankton biogeography be altered due to anthropogenic climate change? and (5) Can a new unifying theory of macroecology be developed based on plankton ecology studies? In this review, we discuss potential future avenues to address these questions, and challenges that need to be tackled along the way.

“…Our findings imply that migratory zooplankton, by virtue of their daily exposure to a wide range of pCO 2 conditions, might not require evolutionary adaptation to future pCO 2 scenarios. In contrast, nonmigratory zooplankton are more likely to experience local extinction in the absence of evolutionary adaptation (50). Direct Arctic studies are therefore required to assess organism and species sensitivities rather than assuming that responses will be the same as those from tropical or midlatitude studies.…”

The Arctic Ocean already experiences areas of low pH and high CO 2 , and it is expected to be most rapidly affected by future ocean acidification (OA). Copepods comprise the dominant Arctic zooplankton; hence, their responses to OA have important implications for Arctic ecosystems, yet there is little data on their current under-ice winter ecology on which to base future monitoring or make predictions about climate-induced change. Here, we report results from Arctic under-ice investigations of copepod natural distributions associated with late-winter carbonate chemistry environmental data and their response to manipulated pCO 2 conditions (OA exposures). Our data reveal that species and life stage sensitivities to manipulated OA conditions were correlated with their vertical migration behavior and with their natural exposures to different pCO 2 ranges. Vertically migrating adult Calanus spp. crossed a pCO 2 range of >140 μatm daily and showed only minor responses to manipulated high CO 2 . Oithona similis, which remained in the surface waters and experienced a pCO 2 range of <75 μatm, showed significantly reduced adult and nauplii survival in high CO 2 experiments. These results support the relatively untested hypothesis that the natural range of pCO 2 experienced by an organism determines its sensitivity to future OA and highlight that the globally important copepod species, Oithona spp., may be more sensitive to future high pCO 2 conditions compared with the more widely studied larger copepods.climate change | diel vertical migration | ecophysiology | pH response O cean acidification (OA) has been highlighted as one of the most pervasive human impacts on the ocean (1). However, observational datasets that link oceanic carbonate chemistry with biotic responses on which to ground predictions of OA impacts remain limited, especially in the most susceptible and rapidly changing ocean, the Arctic (2). Recent observations indicate that several locations in the Arctic already experience seasonal undersaturation with respect to aragonite, concomitantly with elevated pCO 2 and lowered pH conditions (3), and such incidences are predicted to increase as OA progresses (4). However, knowledge of current seasonal and interannual variability in carbonate system parameters for the Arctic Ocean, particularly under winter sea ice, remains limited. Furthermore, information about the ecology of organisms that live in Arctic waters is primarily restricted to summer studies, with only a few investigations being conducted during the ice-covered winter period (5). Hence, predicting how organisms and ecosystems respond to OA is currently restricted to studies from subarctic and/or icefree Arctic systems because of the technical difficulties and costs involved in sampling remote ice-associated Arctic locations. Given that the Arctic is recognized as a "bellwether" for global OA processes (2) and that polar species are potentially more sensitive to these changes due to their reduced metabolic scope (6), this lack of data on Arctic under...

“…Recent predictions about the likely effects of climate change on plankton communities [19,20] have revitalized intensive research on the response of these organisms to temperature shifts [11,15,21]. Among them, studies of geographical variation in Daphnia have provided evidence for both phenotypic plasticity and genetic population differentiation [22][23][24][25].…”

Adaptive phenotypic plasticity and local adaptation for temperature tolerance in freshwater zooplankton

2014

Many organisms have geographical distributions extending from the tropics to near polar regions or can experience up to 308C temperature variation within the lifespan of an individual. Two forms of evolutionary adaptation to such wide ranges in ambient temperatures are frequently discussed: local adaptation and phenotypic plasticity. The freshwater planktonic crustacean Daphnia magna, whose range extends from South Africa to near arctic sites, shows strong phenotypic and genotypic variation in response to temperature. In this study, we use D. magna clones from 22 populations (one clone per population) ranging from latitude 08 (Kenya) to 668 North (White Sea) to explore the contributions of phenotypic plasticity and local adaptation to high temperature tolerance. Temperature tolerance was studied as knockout time (time until immobilization, T imm ) at 378C in clones acclimatized to either 208C or 288C. Acclimatization to 288C strongly increased T imm , testifying to adaptive phenotypic plasticity. At the same time, T imm significantly correlated with average high temperature at the clones' sites of origin, suggesting local adaptation. As earlier studies have found that haemoglobin expression contributes to temperature tolerance, we also quantified haemoglobin concentration in experimental animals and found that both acclimatization temperature (AccT) and temperature at the site of origin are positively correlated with haemoglobin concentration. Furthermore, Daphnia from warmer climates upregulate haemoglobin much more strongly in response to AccT, suggesting local adaptation for plasticity in haemoglobin expression. Our results show that both local adaptation and phenotypic plasticity contribute to temperature tolerance, and elucidate a possible role of haemoglobin in mediating these effects that differs along a cold-warm gradient.
