Abstract The whole‐plant economics spectrum (PES) refers to the trade‐offs among many plant functional traits that are commonly used as indicators of major adaptive strategies, thereby providing insights into distributions, ecosystem processes and evolution. However, there few studies what may be called whole‐PES integrates bark, wood leaf for different types growth habits (evergreen vs. deciduous species). To address this gap in our knowledge, 6 bark traits, 7 (including mechanical support nutrient transport characteristics) 12 chemical, structural physiological 59 representative subtropical woody species were examined using principal component analysis (PCA) determine PES strategies. spectra (BES), (WES) leaves (LES), entire indicated represent resource acquisition strategies conservation clustering on opposite ends PCA axis. A significant correlation was observed 25 traits. data N P levels at hub BES, WES, LES interrelationships. Evergreen had WES LES, thus With exception evergreen clustered conservative side, whereas acquisitive side.

The concept of a root economics space (RES) is increasingly adopted to explore trait variation and belowground resource-acquisition strategies. Much progress has been made on interactions morphology mycorrhizal symbioses. However, exudation, with significant carbon (C) cost (c. 5-21% total photosynthetically fixed C) enhance resource acquisition, remains missing link in this RES. Here, we argue that incorporating exudation into the structure RES key holistic understanding soil nutrient acquisition. We highlight different functional roles exudates phosphorus (P) nitrogen (N) Thereafter, synthesize emerging evidence illustrates how interacts symbioses at level species individual plant contrasting patterns evolved P-impoverished vs N-limited environments. Finally, propose new conceptual framework, integrating three groups traits better capture complexity Such deeper integrated dynamic morphology, will provide valuable insights mechanisms underlying coexistence for sustainable managed systems.

Abstract The priming effect (PE) is a key mechanism contributing to the carbon balance of soil ecosystem. Almost 100 years research since its discovery in 1926 have led rich body scientific publications identify drivers and mechanisms involved.

Feedback between plants and soil microbial communities can be a powerful driver of vegetation dynamics. Plants elicit changes in the microbiome that either promote or suppress conspecifics at same location, thereby regulating population density-dependence species co-existence. Such effects are often attributed to accumulation host-specific antagonistic beneficial microbiota rhizosphere. However, identity host-specificity taxa involved rarely empirically assessed. Here we review evidence for plant-associated microbes propose specific plant-soil feedbacks also driven by generalists. We outline potential mechanisms which generalist pathogens, mutualists decomposers generate differential on plant hosts synthesize existing predict these as function investments into defence, dispersal. Importantly, capacity drive depends not only traits individual but phylogenetic functional diversity communities. Identifying factors specialization generalism plant-microbial interactions modulate impact performance will advance our understanding underlying feedback ways it contributes
