Influence of nitrogen deposition on carbon dynamics in peatlands [PDF]
, 2006 The impact of high levels of nitrogen deposition from the atmosphere (primarily from the combustion of fossil fuels and transportation) on soil carbon fluxes and carbon sequestration pathways in peatlands are uncertain and limit our understanding of ...

New Phytologist, Volume 250, Issue 6, Page 3716-3731, June 2026.Summary Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (gmin), which is highly relevant since it informs on the water depletion dynamics under stress.

Marketing underutilized plant species for the benefit of the poor: a conceptual framework [PDF]
"Modern crop production is based on only a few plant species. Particularly in marginal environments of developing agricultural economies, many less well-known agricultural or non-timber forest species, continue to be grown, managed or collected, thus ...

Ecosphere, Volume 17, Issue 5, May 2026.Abstract Soil extracellular enzymes are produced and excreted by soil microbial organisms. They catalyze many of the biochemical reactions that support crucial ecosystem functions like decomposition, organic matter mineralization, nutrient cycling, and C sequestration.

Coexistence under constraint: Spatiotemporal co‐occurrence in a dryland carnivore guild
Ecosphere, Volume 17, Issue 5, May 2026.Abstract Interspecific competition plays a crucial role in shaping the structure and dynamics of large carnivore guilds. Extreme temperatures and heightened resource heterogeneity in drylands can present additional challenges to intraguild coexistence, potentially making dryland carnivore guilds particularly susceptible to climate change and ...
