“…In other species, such as Pacific white sea bass ( Atractoscion nobilis ), larval fish otolith development in response to elevated CO 2 conditions showed an increased otolith size (area) compared with controls, although it was not determined whether these changes affected orientation and behaviour of young fish, or their survival (Checkley et al , ). Similarly, Frommel et al () found no deleterious effects of realistic changes in pH on the motility of sperm in Atlantic cod ( Gadus morhua ) in the Baltic Sea. By contrast, Ishimatsu et al (personal communication) found that high CO 2 and warm temperature together resulted in high larval mortality in the clownfish Amphiprion ocellaris and in the medaka ( Oryzias javanicus ).…”

ABSTRACT1. Recent and projected future changes in the temperature and chemistry of marine waters around the UK and Ireland are having, and will in the future have, effects on the phenology, productivity and distribution of marine fish and shellfish. However, the overall consequences are still hard to predict because behaviour, genetic adaptation, habitat dependency and the impacts of fishing on species, result in complex species' responses that may be only partially explained by simple climate envelope predictions.2. There is a broad body of evidence that climatic fluctuations are playing an important role in changing fish distributions and abundances, which is discernible against the background of trends in abundance due to fishing. During warm periods, southern species have tended to become more prominent and northern species less abundant. However, the changes in distribution are often more complicated than might be expected from a simple climate envelope approach, partly due to ocean circulation patterns which create invasion routes for southern water species into the North Sea from the south and from the north via the continental shelf west of Britain and Ireland.3. The eventual population-scale impacts of ocean acidification on fish and shellfish are currently very difficult to predict. However, the scant evidence suggests that indirect food web effects arising from the enhanced sensitivity of calcifying planktonic organisms may be important, and the direct effect on fish sensory systems leading to subtle influences on behaviour with possible population-level implications are possible.4. In British waters, the lesser sandeel (Ammodytes marinus) is identified as being at particular risk from climate change. Owing to its strict association with coarse sandy sediments it is unable to adapt its distribution to compensate for warming sea temperatures. Sandeels are a key link in the food web, linking primary and zooplankton production to top predators.

“…Sperm velocity was either not affected by environmental variation, such as increased temperature and decreased water pH in several marine invertebrates (Byrne et al 2010), the Atlantic cod (Frommel et al 2010), or the oyster (Havenhand & Schlegel 2009), or that environmental variation affected males differently in such a way that consistent population variation did not emerge.…”

Using basic ecological concepts we introduce sperm ecology, a framework to study sperm cells.We first describe environmental effects on sperm and conclude that evolutionary and ecological research should not neglect the overwhelming evidence presented here (both in external and internal fertilizers, and in terrestrial and aquatic habitats) that sperm function is altered by many environments, including the male environment. Second, we conclude that the evidence for sperm phenotypic plasticity is overwhelming. Third, we find that genotype-by-environment interaction effects on sperm function exist but their general adaptive significance (e.g. local adaptation) awaits further research. It remains unresolved whether sperm diversification occurs by natural selection acting on sperm function, or on male and female micro-environments that enable optimal plastic performance of sperm ('sperm niches'). Environmental effects reduce fitness predictability under sperm competition, predict species distributions under global change, explain adaptive behavior, and highlight the role of natural selection in behavioral ecology and reproductive medicine.

Working with off spring from a population of cod from the Norwegian coast, however, Frommel et al (2012) and Maneja et al (2013a,b) found a variety of negative effects on older larvae, highlighting the possible importance of differences in population source, duration of exposure, and developmental stages inspected to the observed response.…”

ABSTRACT. New England coastal and adjacent Nova Scotia shelfwaters have a reduced buffering capacity because of significant freshwater input, making the region's waters potentially more vulnerable to coastal acidification. Nutrient loading and heavy precipitation events further acidify the region's poorly buffered coastal waters. Despite the apparent vulnerability of these waters, and fisheries' and mariculture's significant dependence on calcifying species, the community lacks the ability to confidently predict how the region's ecosystems will respond to continued ocean and coastal acidification. Here, we discuss ocean and coastal acidification processes specific to New England coastal and Nova Scotia shelf waters and review current understanding of the biological consequences most relevant to the region. We also identify key research and monitoring needs to be addressed and highlight existing capacities that should be leveraged to advance a regional understanding of ocean and coastal acidification.
