Abstract:
... There has been a reinvigoration of public interest in space exploration in what has been deemed the new space race, which aims to eventually take humans to Mars in the 2030s. This type of Earth‐independent deep space mission presents a multitude of challenges for providing astronauts with adequate nutrition, which are not currently posed by our presence in low earth orbit. For example, there are t ...

Abstract:
... Plant–soil feedbacks (PSFs) and plant–plant competition influence performance and abundance of plants. To what extent the two biotic interactions are interrelated and thus affect plant performance in combination rather than in isolation remains poorly explored. It is also unclear how the abiotic context, such as resource availability, modifies individual and joint effects of PSFs and of plant–plan ...

Nutrient removal by a 4.6-ha urban stormwater treatment wetland system in a 20-ha water/nature park in southwest Florida has been investigated for several years, suggesting that the wetlands are significant sinks of both phosphorus and nitrogen although with a slightly decreased total phosphorus retention in recent years. This study investigates the role of sedimentation on changes in nutrient con ...
