Biotic indices are tools to assess the ecological status of marine systems, and can be based on different metrics (such as ecological groups, specific diversity). The present study applies five biotic indices based on living (stained) benthic foraminiferal assemblages to assess ecological conditions in a wide area of the Mediterranean Sea in the heavily polluted Gulf of Gabes and along the...

Chen, Min ; Arato, Miguel ; Borghi, Lorenzo ; Nouri, Eva ; Reinhardt, Didier

In: Frontiers in Plant Science, 2018, vol. 9, p. -

Arbuscular mycorrhiza (AM) is the most common symbiotic association of plants with microbes. AM fungi occur in the majority of natural habitats and they provide a range of important ecological services, in particular by improving plant nutrition, stress resistance and tolerance, as well as soil structure and fertility. AM fungi interact with most crop plants including cereals, vegetables, and...
