Few studies have evaluated the joint effects of elevated temperature and pCO2 on marine organisms. In this study we investigated the interactive effects of Intergovernmental Panel on Climate Change predicted temperature and pCO2 for the end of the 21st century on key aspects of larval development of the American lobster, Homarus americanus, an otherwise well-studied, iconic, and commercially prominent species in the northeastern United States and Atlantic Canada. Our experiments showed that larvae (stages I–III) and postlarvae (stage IV) reared in the high temperature treatments (19 °C) experienced significantly lower survival, developed twice as fast, and had significantly higher oxygen consumption rates, than those in ambient treatments (16 °C). Larvae from the ambient temperature/high pCO2 (750 ppm) treatment had significantly longer carapace lengths, greater dry masses in stages I–III and higher C: N ratios in stage IV than larvae from all other treatments. Stage IVs raised in the high pCO2 treatment at 19 °C had significantly higher feeding rates and swimming speeds than stage IVs from the other three treatments. Together these results suggest that projected end-century warming will have greater adverse effects than increased pCO2 on larval survival, and changing pCO2 may have a complex effect on larval metabolism and behaviour. Understanding how the most vulnerable life stages of the lobster life cycle respond to climate change is essential in connecting the northward geographic shifts projected by habitat quality models, and the underlying physiological and genetic mechanisms that drive their ecology.

Adaptation Action

A wide range of climate vulnerability and risk assessments have been implemented using different approaches at different scales, some with a broad multi-sectoral scope and others focused on single risks or sectors. This paper describes the novel approach to vulnerability and risk assessment which was designed and put into practice in the United Kingdom's Second Climate Change Risk Assessment (CCRA2) so as to build upon its earlier assessment (CCRA1). First, we summarize and critique the CCRA1 approach, and second describe the steps taken in the CCRA2 approach in detail, providing examples of how each was applied in practice. Novel elements of the approach include assessment of both present day and future vulnerability, a focus on the urgency of adaptation action, and a structure focused around systems of receptors rather than conventional sectors. Both stakeholders and reviewers generally regarded the approach as successful in providing advice on current risks and future opportunities to the UK from climate change, and the fulfilment of statutory duty. The need for a well-supported and open suite of impact indicators going forward is highlighted. This article is part of the theme issue ‘Advances in risk assessment for climate change adaptation policy'.

Abstract Egg and larval development times of Gerris odontogaster (Zett.) (COD), G. lateralis Schumm. (LAT), G. lacustris (L.) (LAC), G. thoracicus Schumm. (THO) and G. rufoscutellatus Lt. (RU) were studied. In species OD they are dependent on temperature. The roles of photoperiod, crowding and food remain open, even if continuous light seems to have a retarding effect on the larval development of OD and LAC. The development times of the subsequent instars of OD, LAT and LAC were shown to be of unequal lengths. When the development rates of different species were compared in 25―26°C, the species sequence from fastest to slowest was LAT, THO, LAC, OD and RU, i.e., disregarding RU and THO, just the opposite of the order experienced in nature in Finland. This raised the question of why the fastest species have not displaced OD in the microclimatically warmest habitats. The answer is supposed to lie in the seasonal, environmentally determined alary dimorphism of OD, which adapts it better than other species to microclimatically warm but at the same time temporary habitats.
