Abstract:
... Open‐access data associated with research efforts depend upon managing, packaging, and preserving data for sharing with collaborators and the public. The U.S. Long‐Term Ecological Research (LTER) Network, established in 1980, provides an early example of embedded data management supporting long‐term, place‐based research and contributes to our understanding of the enactment of open data access wit ...

Abstract:
... Atmospheric nitrogen (N) deposition can profoundly affect methane (CH₄) oxidation; however, how it responds to the cessation of N addition has rarely been reported. An incubation experiment was conducted using soils from plots treated with long-term N addition to estimate the soil CH₄ oxidation potential. The results showed a unimodal relationship between the levels of soil CH₄ consumption and N a ...

Abstract:
... Soil respiration (SR) has been demonstrated to be affected by nitrogen (N) enrichment. However, most studies examine the effect of N enrichment on SR using only two levels of N treatments (i.e. control vs N enrichment). Current understanding of SR responses to varying rates of N enrichment remains unclear. A field manipulative experiment with eight levels of N addition (0, 1, 2, 4, 8, 16, 32, 64 g ...

Abstract:
... 1. Seed dispersal by ants, i.e. myrmecochory, is important in drylands because ants may contribute to overcoming the typical resource limitation imposed on plants in these environments. Dispersal distance and directed dispersal of seeds to nutrient‐enriched ant nests benefit plants by reducing parent or sibling competition and improving growth, survival, and reproduction. 2. This study investigate ...

Yet, these explanatory models t ...

We asked how the size of kurgans, their isolation and other lands ...

Although forage consumption occurs at community level, most studies focused on species-level changes of forage quality. The quantitative and qualitative changes of forage production are driven by species-specific trait, intra-specific plasticity, and species turnover. We examined the changes in forage production and ...
