Abstract Understanding how climate change may influence ecosystems depends substantially on its effects on foundation species, such as the ecologically important giant kelp (Macrocystis pyrifera). Despite its broad distribution along strong temperature and pH gradients and strong barriers to dispersal, the potential for local adaptation to climate change variables among kelp populations remains poorly understood. We assessed this potential by exposing giant kelp early life stages from geneticall...

Abstract Capabilities of remotely operated vehicles (ROVs) have increased substantially in the last decade, and mini-ROV designs are now able to conduct visual research frequently conducted by snorkellers or divers in shallow marine environments. There are logistical, financial and experimental benefits of using mini-ROVs over snorkellers or divers, yet the adoption of mini-ROVs for common shallow underwater research tasks has not been widespread. To assess the capabilities of mini-ROVs to sampl...

Abstract Ocean acidification (OA) projections predict ocean pH to decline between 0.2 and 0.4 by 2100 with potential negative consequences for marine calcifiers without acclimation or adaption strategies to accomodate greater [H+] in seawater. Biotic control of calcified reef macroalgae thalli surface diffusive boundary layer (DBL) chemistry may overcome low pH in seawater as one strategy to accommodate OA conditions. To investigate this strategy, we examined surface DBL O2 and pH dynamics in fi...

Abstract Otolith shape is an efficient tool for fish stock discrimination. Therefore, it is crucial to identify the environmental parameters that could influence otolith morphogenesis and growth. Current global ocean warming negatively affects the production of polyunsaturated fatty acids (EPA and DHA) by phytoplankton and thus their availability in marine food webs. As EPA and DHA are essential nutrients for most fish species, their deficiency could affect many aspects of fish physiology, notab...

Abstract Calanus is one of the best studied genera of Arctic zooplankton, but still we know very little about the males since they are short-lived and mainly present in winter. Their short life-span compared to females is assumed to be a combination of high mating activity, no feeding and consequential depletion of lipid stores. In this study we tested 1) if the life span of male Calanus glacialis is limited by their lipid storage reserves and 2) if males are capable of feeding and utilize food ...

Abstract Climate change is predicted to alter ocean chemistry through warming temperatures, increases in CO2 (i.e., ocean acidification), and reductions in dissolved oxygen (DO) (i.e., hypoxia). Past research has shown that early life stages of marine fishes are sensitive to all three stressors, but with sometimes different directions of response. In this study, we examined the separate effects of ocean acidification and hypoxia on otolith growth in two species of juvenile rockfish (copper rockf...

Abstract Viruses are a major source of mortality for phytoplankton and bacteria and are therefore seen as drivers of food web dynamics and biogeochemical cycling in the marine pelagic environment. Previous studies have shown that aquatic viruses adsorb to suspended sediment, which theoretically decreases the mortality pressure on their microbial hosts. This process is of particular ecological importance in the Arctic, where coastal systems contain large amounts of suspended fine-sediment, suppli...

Abstract Reef-building corals are threatened by multiple stressors, including rising ocean temperatures due to anthropogenic climate change, and tissue abrasion inflicted by increasing frequencies of recreational diving on tropical reefs. Both can impair coral growth and survival, but interactive effects of temperature and abrasion remain unknown. We conducted laboratory experiments to investigate the metabolic physiology of endangered Caribbean staghorn corals Acropora cervicornis (Lamarck, 181...

Abstract Natural fluctuations in dissolved oxygen are an important physiological challenge faced by marine organisms. This is particularly true of intertidal species that may become trapped in bodies of water where oxygen becomes rapidly depleted, or which may be emersed and exposed to elevated oxygen, but without respiratory organs adapted for uptake of oxygen from air. We sought to determine whether oxygen handling approaches differ in two species of sea cucumber, Cucumaria miniata and Parasti...

Abstract Increased temperatures caused by anthropogenic climate change are becoming a major challenge for species. In particular, species that migrate over long distances are affected by altered climatic conditions at the various sites they frequent and en route. Here, we investigated whether climatic conditions experienced by sea turtles during their migration would change in the future. We focused on the post-nesting migrations of female loggerhead sea turtles (Caretta caretta) in the Mediterr...
