Highlighting the role of biota in feedback loops from tundra ecosystems to the atmosphere

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 12

The rapid climatic and environmental changes observed in the Arctic across globe general call for reliable model projections. In recent years our understanding of ongoing future through ecosystem modelling has increased tremendously. Yet, most models do not consider many feedback loops at play natural ecosystems. Particularly those influenced by biota, beyond vegetation to some extent microbes, are often neglected. As a first step towards better integration biotic influences into models, we provide broad overview various ways biota may influence between high-latitude biosphere atmosphere. We focus specifically on three key tundra atmosphere (carbon dynamics, albedo permafrost thaw) compartments (vegetation, decomposers herbivores) these. multifaceted appear patchy both space time. However, still important roles modulating loops, including these dynamics magnitude, accuracy credibility projections likely improve.

Effects of Different Fertilization Treatments on Leaf Litter Quality in a Plantation in Heilongjiang Province, China

Forests, Journal Year: 2024, Volume and Issue: 15(12), P. 2193 - 2193

Litter decomposition is a highly complex physical and biochemical process that plays crucial role in promoting energy transformation forest ecosystems. This study examines the impact of different concentrations nitrogen compound fertilizers on quality litter plantation Populus euramericana ‘N3016’ × ussuriensis. The major components elemental contents from layers (the undecomposed layer semidecomposed layer) were analyzed across various months. Overall, application fertilizer or did not significantly alter cellulose, lignin, potassium (K) layers. Nitrogen increased average content (U-layer) (N) phosphorus (P) by 0.220% 0.009%, respectively. Compound U-layer 0.055%. These findings suggest while fertilization can increase initial N P to some extent, it has minimal overall quality. Future research should be focused effects climatic conditions, soil properties, fauna, microbial activity decomposition.
