Low availability of functional seed trait data from the tropics could negatively affect global macroecological studies, predictive models and plant conservation

Abstract: Background Plant seeds have many traits that influence ecological functions, ex situ conservation, restoration success and their sustainable use. Several seed traits are already known to vary significantly between tropical and temperate regions. Here we present three additional traits for which existing data indicate differences between geographical zones. We discuss evidence for geographical bias in availability of data for these traits, as well as negative consequences of this bias. … Show more

“…Thus, more work is needed to study and measure seed traits, including dormancy, in the world's flora, especially in the understudied regions, such as the tropics and the Arctic (e.g. Visscher et al ., 2022).…”

“…Despite these advances, current efforts are biased to specific floras or habitats of mid-latitude temperate biomes, with the major exception of Brazil (Ord oñez-Parra et al, 2023). Large amounts of the Earth's biodiversity hotspots remain unexplored by global-scale germination analyses, especially in tropical areas and continents such as Africa or parts of Asia (Hughes et al, 2021;Visscher et al, 2022).…”

“…Many species of plants rely on regeneration from seed-banks (dormant seeds in the soil). Seed-banks are a major factor in the persistence of certain species [3,[7][8][9][10][11] and are particularly important in plant communities that are subjected to extreme environmental events or frequent disturbances such as: fire, seasonal drought, periodically flooded areas or agricultural fields [5,6,[10][11][12][13][14]. Furthermore, seed-banks play a vital role in the regeneration of tropical rainforests by maintaining the ecological and genetic diversity of populations and communities [14][15][16].…”

“…In general, the seeds of pioneer tree species tend to dominate soil seed-banks [10,13] and seeds from these species are the first to germinate following disturbances [2,10,13]. Factors that influence the abundance and species composition of soil seed-banks in tropical rainforests include the following: land use history, landscape composition and configuration, floristic composition of current and past standing vegetation, phenology, seed physiology and dispersal mode [5,6,8,10,12,13,17,18]. Contemporary land use in tropical areas has strong and long-term lasting effects on the density of seeds stored in the soil, in their germination capacity and on their persistence [5,6,[8][9][10]12,13,19].…”
