Abstract:
... Although the impact of ocean acidification on marine bivalves has been previously investigated under mainly controlled laboratory conditions, it is still unclear whether the impact of acidification on sediment-burrowing species differs between those within or without sediment. In order to fill this gap in our knowledge, we compared shell properties of the infaunal Manila clam (Ruditapes philippina ...

Abstract:
... Distinct cropland acidification has been reported in China due to nitrogen (N) fertilizer overuse. However, the impacts on food production and thereby on food security are largely unknown. Yield losses in the period 1980–2050 were therefore assessed by simulating soil pH changes combined with derived pH-yield relationships for wheat, maize and rice. If the N fertilizer input continues to increase ...
