Searching for early warning signals of dieback in Mediterranean forests |

Álvaro Gaytán and Lorena Gómez-Aparicio, Institute of Natural Resources and Agrobiology of Seville (IRNAS-CSIC), discuss their article: Evidence for linkages between the root elementome and oak decline in Mediterranean systems invaded by soil-borne pathogens Mediterranean woodland in southern Iberia, where holm oaks and dense shrublands shape one of Europe’s most biodiverse landscapes (photo by Lorena Gómez-Aparicio).

How are plant and soil microbial diversity linked across mountain forests? |

Jiayun Zou, Technical University of Munich, discusses his article: Biodiversity associations between aboveground and belowground communities in mountain forests across different climatic regions How tightly are the biological communities above and below the forest floor connected? In mountain forests, those associations remain poorly understood. While plants and soil microbes interact intimately, such as through symbioses […]

What controls biodiversity on natural islands in hyperseasonal tropical savannas? |

Henrique Augusto Mews, Universidade Federal de Rondonópolis in Brazil, discusses his article: Unravelling the drivers of island species richness in tropical savannas Many landscapes contain “island-like” habitats: patches of suitable conditions surrounded by an inhospitable matrix. How species diversity is regulated in these systems remains surprisingly poorly understood. In tropical savannas, such as the Cerrado […]

Asymmetric adaptation drives rapid evolution as an invasive plant expands northward |

Rui Wang, Institute of Plant Protection of the Chinese Academy of Agricultural Sciences, discusses their article: Asymmetric adaptation across a core–periphery climatic gradient drives rapid phenological evolution and range expansion in an invasive plant When we think about plant invasions, we often picture species spreading quickly, competing with native plants, and causing problems for ecosystems […]

Insects and non-woody plants slow down tropical forest succession |

Kari Sogera Iamba, University of South Bohemia and the Institute of Entomology of the Czech Academy of Sciences, discusses his article: Insects and non-woody plants slow down tropical forest succession: A community-wide experiment in Papua New Guinea We investigated the factors driving rainforest regeneration in canopy gaps created by tree falls or selective logging. Ecological […]

How they jointly shape interactions among plant, arthropod, and soil nematode functional groups in temperate grasslands |

Feixue Yu, Inner Mongolia University, discusses her article: Nitrogen addition weakens drought-driven coupling between plant, arthropod, and soil nematode functional groups The concurrent increase in drought and atmospheric nitrogen deposition has profoundly impacted multitrophic biodiversity and ecosystem functioning in grasslands. Nitrogen enrichment is frequently assumed to alleviate drought stress by stimulating plant growth, but this […]

How dynamic traits help them live together |

Guochun Shen and Jing Yang, East China Normal University in Shanghai, China, discuss their article: Shifts in above- and belowground trait dissimilarity under competition mediate the future impact of neighbors When we walk into a forest, it is easy to picture trees competing for light, water, and nutrients. Some seedlings race upwards and cast their […]

Dominant species mitigate grassland multifunctionality during drought in Inner Mongolia |

Jiaqi Chen and Wentao Luo, Institute of Applied Ecology of the Chinese Academy of Sciences, discuss their article: Dominant species determine drought effects on grassland multifunctionality The increasing frequency of extreme drought events poses a severe threat to grassland ecosystem multifunctionality—a metric aggregating multiple ecosystem functions. However, the ecological mechanisms driving these impacts remain contentious. […]

Root exudate traits vary independently from plant growth strategies |

Suwan Ji and Guanghui Lv, Xinjiang University, discuss their article: Intraspecific competition drives orthogonal variation in root exudate metabolic and functional traits in seedlings of a dominant species In plant ecology, competition is a fundamental process regulating population dynamics. While plants appear stationary, they are actively engaging with their environment and neighbours in many ways, […]

How do past disturbances shape tree growth? |

Yihong Zhu, University of California, Berkeley, discusses her article: Legacy effects under an emerging novel disturbance regime: A memory-based framework to quantify tree growth responses Emergent novel disturbance regime Moderate-severity disturbances, such as drought, pathogen irruptions, and prescribed fire, may not cause widespread tree mortality, but can leave lingering impacts on surviving trees. Such disturbances […]
