In a pioneering initiative, researchers from Unesp and the Federal University of Minas Gerais (UFMG) developed a database called Cerrado Plant Traits (CPT). This collection gathers the functional characteristics of about two thousand native plant species of the Cerrado.
The project, started in 2024, centralizes data collected by more than one hundred Brazilian researchers working in the biome. The expectation is that CPT will help increase the presence of the planet's most diverse tropical savanna in global databases, assisting ecologists and specialists in designing research and restoration projects for the biome.
Functional characteristics refer to the morphological, physiological, anatomical, and phenological attributes of plants, explaining how each species interacts with its environment. Currently, the project has cataloged over one hundred thousand records related to approximately two thousand species, all standardized and made available under an open access policy. The researchers detailed CPT in an article in the journal Annals of Botany, describing the data collection and standardization method and pointing out the main deficiencies.
CPT covers a total of 154 functional characteristics, divided into seven groups according to the branches of plant morphology: whole plant, leaf, stem, root, flower, fruit, and seed. For example, the whole plant section includes data on height and regrowth capacity, while the fruit section provides information on coloration and traits related to seed dispersal. For the stem, information such as bark thickness, wood density, and water retention capacity was gathered.
The work to create this exclusive Cerrado repository began in 2024, following a meeting between biologists from Unesp and UFMG. Davi Rossatto, a professor at the Department of Biology of the Faculty of Agrarian and Veterinary Sciences (FCAV) at Unesp, explained that although his projects had already generated a large volume of data, this material remained restricted to specific groups or articles, without sharing. He is one of the initiators of the initiative.
Rossatto observed that, despite the existence of similar databases focused on temperate forests in Europe, the United States, and China, a collection dedicated exclusively to the functional characteristics of Cerrado plants is unprecedented. Alessandra Fidelis, a biologist at Unesp, and Fernando Silveira, a professor at UFMG, led the coordination of CPT.
The first steps involved contacting fellow researchers to present the project. After presentation meetings, several collaborators joined, agreeing to submit their data for standardization and processing, and are listed as creators of CPT in future scientific works.
The Cerrado belongs to the group of tropical savannas, ecosystems with high plant diversity. However, the Brazilian biome has specificities that attract international interest but remains underrepresented in large global databases. The creation of CPT aims to mitigate this imbalance.
In addition to supporting research, CPT can aid in the restoration of the Cerrado by providing technical support for regeneration projects. Rossatto emphasizes that instead of relying solely on the species name, functional characteristics can be more crucial for planning area recovery, allowing specific knowledge to be applied to the areas to be restored.
This open-access repository allows scientists worldwide to test ecological hypotheses on regional or global scales. According to Rossatto, analyzing these characteristics enables more detailed ecological comparisons, even allowing researchers from Africa or Australia to use the database to compare savannas from the three continents.
Current records cover preserved, degraded, and restored environments, with a predominance of whole plant and leaf characteristics. However, subterranean and reproductive characteristics are less represented. Future priorities include expanding the number of species (estimated between 12 and 13 thousand native species among angiosperms only), increasing geographical coverage, and diversifying record categories.
The initial survey identified asymmetries, such as the need for greater coverage in regions like Matopiba, an area under strong agricultural pressure. The underrepresentation of root functional characteristics was also noted, due to the difficulty and cost of study. Rossatto justifies the abundance of leaf data because they are easily removed for studies and are vital for plant metabolism.
Rossatto believes that with the established database, it will be possible to seek funding to fill gaps and expand coverage. He compares CPT to a software in its version 1.0, indicating that development will continue with a focus on a more accessible interface and the inclusion of new collaborators.
