After US also Europe falls prey to invasive Drosophila suzukii – plague threat

invasive drosophila fruit fly

Drosophila suzukii caught in Spain. Out of 3,000 Drosophilae species only two are damaging to fruit crops. Here is one, invading from Asia to the US and now Europe.

Coming from the Asian continent, Drosophila suzukii has only been in Spain for a short time. Far away from slipping through into the Iberian Peninsula, it accelerated towards the north of Europe where it has already crossed the Alps. Amongst its preferred target are cherries and red fruits but any type of fruit is suitable for it to lay its eggs. This insect is posing a threat to the fruit of more and more European countries.

Biologists at Bielefeld University have developed a new method for quantifying the effect of non-native species on ecosystem functioning.

They can now estimate whether native plants in the neighbourhood of invasive species incorporate the nitrogen fixed by the latter.

Mediterranean biodiversity versus a globalising planet: from Suez Canal to your tuna pizza

“In reserves off Spain and Italy, we found the largest fish biomass in the Mediterranean. Unfortunately, around Turkey and Greece, the waters were bare” – Enric Sala, National Geographic Society.

Quantifying the invasive species problem, Florida´s case: 137 non-native reptiles & amphibians

Last week we took a look at the slowness of species migration before the age of the 747. Today we speed up time by a thousand – to get to the ecological reality of globalisation.

Inter-ocean transport before the age of globalisation

What happens on a daily basis now, used to occur just twice in millions of years – for this one horn snail at least. Snail’s airlift chance before age of globalisation: mistaking heron’s leg for reed?
