Glaciations may have larger influence on biodiversity than current climate

also present in the south, and there is no species exclusive to the northernmost area. According to Hortal, "this is an effect of the difficulty of adapting to cold climate that still exists, as the north does not hold unique species adapted to the cold."

This feature is consistent with the second observation, based on the age of the species present in each area. The study results show that the species that have been able to re-colonize the north are also those that have evolved most recently." Although the adaptation to cold climates started before the last glaciation, these species belong to the newer phylogenetic branches of the Scarabaeidae," says the researcher from CSIC.

Shared influence

The current distribution of scarabs in Europe demonstrates, therefore, that certain influence of the last ice age is still maintained. According to Hortal, "it is not that the current climate does not affect biodiversity, but rather that the impact of past climate change is hiding under the influence of present conditions." The reason why such impact has not been detected so far is that both cause similar effects, i.e., less species in the North of Europe. The CSIC researcher says that: "current biodiversity patterns are therefore a mixture of past climate effects, current conditions and the evolutionary history of the species."

The results of this investigation show that the consequences of major climate changes persist over a very long term. According to Hortal, "this work should be taken into account when analyzing and forecasting the consequences of the global warming currently experienced by the Earth." The researcher concludes: "If the temperature continues to rise, some climates that never occurred during the recent history of our planet may appear, and we do not know which species, both animal and plant, will be able to adapt to them; in fact, it is possible that many of them will not be able to live in these new climates."
