Identifying ecosystem key factors to support sustainable water management [PDF]
There is a growing consensus that sustainable development requires a behavioral change, forced by firm decision-making. However, existing decision-supporting tools are unlikely to provide relevant information, hampered by the complexity of combined socio-

Extracting Additional Information From Biotic Index Samples [PDF]
Macroinvertebrates were collected from a small midwestern stream over a 3-year period as part of a non-point source pollution study. Temporal and spatial variability in standard biotic index values (BIs) were computed and compared with variability ...

Nitrification amplifies the decreasing trends of atmospheric oxygen and implies a larger land carbon uptake [PDF]
[1] Atmospheric O-2 trend measurements are used to partition global oceanic and land biotic carbon sinks on a multiannual basis. The underlying principle is that a terrestrial uptake or release of CO2 is accompanied by an opposite flux of O-2.

Arcopilus aureus : a valuable endophytic associate of hazelnut
Endophytic fungi are increasingly being considered for their ecological role and effects on plant protection and nutrition. Their contribution in improving fitness can be particularly relevant in the case of semi-extensive tree crops, such as hazelnut ...
