The invasion of hammerhead flatworms is not over yet

In the the last years, predatory land flatworms have been introduced in many locations because of the trade of exotic plants.

It turns out that they have not colonised all regions at risk yet, which demonstrates a need for increased vigilance in these areas.

Cirad – Crop diversification enhances yields, biodiversity and ecosystem services

The article, published in Global Change Biology on 18 July 2021, assembles for the first time a substantial body of empirical evidence on the positive impacts of cultivated biodiversity on agroecosystems.
Crop diversification was found to enhance crop production by 14% and associated biodiversity by almost 25%. Water quality was improved by 50%, pest and disease control by over 63% and soil quality by 11%.

Great tits living in cities are genetically different from great tits in the countryside. This is what researchers have found in a unique study, where they examined populations of great tits in nine large European cities.

The researchers compared the city bird genes with the genes of their relatives in the countryside. It did not matter if the great tits lived in Milan, Malmö or Madrid: in order to handle an environment created by humans, the birds evolved in a similar way.
