Rate My Professor James Tsakalos

Tsakalos's research focuses on plant ecology, plant traits, community assembly, functional diversity, clonality, dark diversity, and the effects of pathogens like Phytophthora cinnamomi and human activities on vegetation. He has produced over 65 publications, datasets, and software tools. Key publications include the highly cited "TRY plant trait database – enhanced coverage and open access" (2020, co-authored, 2136 citations), "Global impoverishment of natural vegetation revealed by dark diversity" (2025, Nature), "Unravelling the clonal trait space: Beyond above‐ground and fine‐root traits" (2024), "The diversity of within-community plant species combinations: A new tool for assessing changes in forests and guiding protection actions" (2024), "Multiple drivers of functional diversity in temperate forest understories: Climate, soil, and forest structure effects" (2024), "Forest biomes of Southern Africa" (2022), "Composition and ecological drivers of the kwongan scrub and woodlands in the northern Swan Coastal Plain, Western Australia" (2019), and contributions to R packages such as "climenv: Download, extract and visualise climatic and elevation data" (2023) and "comspat: an R package to analyze within‐community spatial organization using species combinations" (2022). His work supports global efforts in plant trait databases, biodiversity monitoring, and conservation strategies across shrublands, forests, and grasslands.
