The project ForbAge will use growth ring analysis to study the longevity of plant individuals (or ramets) and measure stem anatomical characteristics for a large number of perennial dicotyledonous forb species in the grasslands. The project will extend trait-based ecology to a demographic perspective, which is important to understand the viability and persistence of plant populations as well as the long-term stability of plant communities.


We will focus on the following questions:

  1. How do management and biodiversity affect the average age of individuals (or ramets) of a large number of dicotyledonous forb species in grasslands?
  2. How are the spectrum and distribution of life spans of individuals (or ramets) of four selected frequent forb species related to population sizes and the temporal stability of plant populations? Do management and diversity of grasslands influence the distribution of life spans in plant populations?
  3. Do management, diversity, and regional differences between the exploratories affect growth ring widths and the expression of stem anatomical traits?
  4. How are life spans and stem anatomical traits related to phylogeny and other functional traits of the studied species?
