Spatial exploration of plant functional types: insights from bibliometric meta-analysis

The realm of ecology and environmental studies places immense significance on the concepts of plant functional traits (FTs) and plant functional types (PFTs), especially through spatial lens. The present study presents a bibliometric analysis of research on FTs and PFTs over the past decades (1993 to 2023). By analyzing 277 relevant publications, key trends, influential authors, and major contributors to this field, notable figures including Swenson NG, Reich PB, and Pottier J were identified. The analysis highlights the growing global interest in FTs and PFTs, particularly in the USA, Germany, and China, and the role of leading institutions such as the University of Oxford, Universidad Rey Juan Carlos, and the Chinese Academy of Sciences. A significant finding in this study is the increasing use of spatial technologies like Geographic Information Systems (GIS) and remote sensing, which have enhanced the understanding and categorization of PFTs. This work not only underscores the global scope and collaborative nature of this research but also identifies emerging areas for further exploration, particularly in the application of spatial techniques to ecological and environmental studies. In essence, this bibliometric analysis accentuates the synergy between spatial techniques and PFT research, emphasizing the potential of these innovations to drive future advancements in plant ecology.
