As warming intensifies drying trends, tree species respond differently, especially across the conifer–broadleaf divide. Yet it remains unclear how these contrasting groups reorganise their relative composition under progressive aridification. Here, we investigated Abies fargesii and Quercus mongolica growing in the middle and eastern section of the Qinling Mountains, a transitional zone between the warm‐temperate and subtropic...

Understanding the dynamics of the phytoplankton community in the marginal seas of the Southern Ocean is crucial for delineating its role in global carbon cycling. This study investigated spatiotemporal variations in phytoplankton community structure and organic carbon pools in the Cosmonaut Sea, East Antarctica, with an emphasis on spatial heterogeneity and environmental drivers during late austral summer (February). Water sam...
