Greeting to all nutty and seedy ecologists!
I am compiling a database and bibliography of all records of interannual variation in seed set of perennial plants that set seed in multiple years (i.e. iteroparous/polycarpic plants). As such, I was wondering if you might have or know of such data that I have not found yet. This could be data from seed traps, counts of fruits/seeds on plants, forest floor quadrats, timed seed/fruit/cone counts, qualitative estimates of fruit/seed crop. Often, these data are from trees and shrubs, but they could also include long-lived grasses/forbs/succulents. The key features that would make data useful to this database would be 1) four or more years of seed/fruit set data from the same site / set of plants / traps 2) knowing what plant species the fruits/seeds come from 3) knowing roughly where the sites are and how the data were collected. Currently, I have compiled a database with ca. 1000 such time series from around the world, but I know that I am missing some --especially 1) cone/seed crop estimates for wildlife or forestry management, which often reside with regional natural resource departments 2) unpublished or ongoing studies 3) studies that just might have slipped through my fingers for other reasons. It would be wonderful to make this list as complete as possible. If you know of or maintain any of these datasets and would be interested in them being added to this database, please contact me at: [email protected] All the best! Ian Pearse [email protected]
