Small crustaceans and climate change

This is a video of a copepod, a relative of Calanus finmarchicus, in the Indian Ocean.

Researchers find animal with ability to survive climate change

Queen’s researchers have found that the main source of food for many fish — including cod — in the North Atlantic appears to adapt in order to survive climate change

Billions of Calanus finmarchicus, a plankton species, which are just a few millimetres in size, live in the waters of the North Atlantic where the research was carried out.

It showed they responded to global warming after the last Ice Age, around 18,000 years ago, by moving north and maintaining large population sizes and also suggests that these animals might be able to track the current change in habitat.

The effect of global climate change on the planet’s ecosystems is one of the key issues scientists are currently focussing on and the research has been published in Proceedings of the Royal Society B, a publication of the national academy of science of the UK and the Commonwealth, today.

One of the main predicted effects of climate change is a forced shift in species’ distribution range.

The study leader, Dr Jim Provan, from Queen’s School of Biological Sciences, said the discovery that that a species has a feature which helps it cope with global warming is a rare example of good news.

  1. Climate change — the case for public ownership

    By Trent Hawkins

    Arising out of the UK Climate Camp in August 2008 there has developed an
    interesting debate between Ewa Jasiewicz, an activist in Britain, and
    well-known radical columnist George Monbiot about the role of so-called
    “state solutions” to climate change. Jasiewicz’s article, published on
    the Guardian website[i] and entitled “Time for a Revolution”, was an
    attack on Monbiot for a “controversial presentation [at climate camp]
    … in which he endorsed the use of the state as a partner in resolving
    the climate crisis”.
