Change in distribution and range size of several demersal fish species in the BCLME over the period 1985–2010, including both commercial and non-commercial fish populations are analysed to highlight the complex nature of the response of fish population to climate change.Abstract:
Distributional change, expressed as range expansion or contraction
, has been observed in many marine populations and related to changes in the environment. The extent of such distributional changes is also expected to increase in response to future climate change. The Benguela Current Large Marine Ecosystem (BCLME) which adjoins the south-western coast of Africa is a global marine hotspot with long-term warming occurring over a large area. The area is also an important centre of marine food production for three countries—South Africa, Namibia and Angola and is considered to be vulnerable to future climate change or increased climate variability. In this study we analysed change in distribution and range size of several demersal fish species in the BCLME over the period 1985–2010, including both commercial and non-commercial fish populations. Some of the observed changes in distribution and range size correspond to what is expected with increased warming whereas others appear to the contrary. Overall the results of the study highlight the complex nature of the response of fish population to climate change.read more

TL;DR: The physics, chemistry, and ecology of the oceans might be affected based on two CO2 emission trajectories: one business as usual and one with aggressive reductions, consistent with the Copenhagen Accord of keeping mean global temperature increase below 2°C in the 21st century.

TL;DR: In this article, the authors review evidence for the responses of marine life to recent climate change across ocean regions, from tropical seas to polar oceans, and find that general trends in species responses are consistent with expectations from climate change, including poleward and deeper distributional shifts, advances in spring phenology, declines in calcification and increases in the abundance of warm water species.

TL;DR: Compiling a global geo-database of >30,000 range shifts, the authors show that marine species closely track shifting isotherms, whereas terrestrial species lag behind, probably due to wider thermal safety margins and movement constraints imposed by human activities.

Climate change and marine vertebrates
TL;DR: Marine fish, mammal, turtle, and seabird responses to climate change are reviewed and the nexus of metabolism relative to ecosystem productivity and food webs appears key to predicting future effects on marine vertebrates.
