In douglasgscofield/dispersalDiversity: Analyse individual and genetic diversity of dispersal processes in biological populations

Description

A dataset containing seed source tree assignments for acorns of valley oak (Quercus lobata), harvested in 2002 from acorn woodpecker (Melanerpes formicivorus) granaries. Data were collected in oak savanna habitat in central California. Acorn woodpeckers store acorns in central granaries, and different woodpecker social groups maintain different granaries.

Format

Matrix with 20 rows and 50 variables.

Details

The dataset is stored as a matrix, with the variables are as follows:

• Granary_Year, the row names, indicating the granary identifier and year of harvest

• Source, the column names, indicating the identified source of harvested acorns. Where the source name is prefixed with "S", the source tree was identified among the adult trees genotyped at the study site. Where the prefix is "U", the source tree was not genotyped and thus not located, but could still be identified as unique among the harvested acorns.

Each element of the matrix represents a count of the number of acorns harvested from that granary in 2002 that were assigned to that seed source tree.

Some, but not all, granaries and seed sources are common between this dataset and granaries_2004_Qlob, also available in this package. See Thompson et al. (2014) for more study details.
