Estimating seed mass and volume from linear dimensions of seeds
Casco, H.; Dias, L.S.Seeds from eight species common in soil banks and covering two orders of magnitude of seed size were individually weighted and measured. Adopting simple but sound assumptions on seeds geometry, seed length and width together or not with thickness were found to be highly accurate estimators of seed mass and volume at intra- and inter-specific levels. Thereby, by abstracting the vast amount of published data of s...
Modeling size-number distributions of seeds for use in soil bank studies
Casco, H.; Dias, A.S.; Dias, L.S.Knowledge of soil seed banks is essential to understand the dynamics of plant populations and communities and would greatly benefit from the integration of existing knowledge on ecological correlates of seed size and shape. This paper aims to establish a feasible and meaningful method to describe size-number distributions of seeds in multi-species situations. For that purpose, size-number distributions of seeds...
