To explore the importance of interactions, light limitations, and density in annual plant species in the San Joaquin Desert.
Dates
Trials from October to December 2018 under controlled, high-light conditions in greenhouse at York University.
Meta-data
pot label label on the pot
census census number
calendar date DD/MM/YY
rep replicate
density planted number of seeds of native species (Plantago insularis, Phacelia tanacetifolia, and Salvia columbariae planted in the pot (additive study/with replacement)
light treatment factor Light as a factor at 2 levels: ambient light or shaded (to replicate shrub canopy) conditions
brome treatment factor Exotic brome density as a factor at 2
levels: low Bromus madritensis (density of 5 per pot) and high Bromus madritensis (density of 10 per pot)
brome The number of germinated individuals of Bromus madritensis in the pot
morphometric metrics list mean values per pot per species
biomass for each species after drying for 48hrs at 67F
light measured between noon and 1pm using a Licor LI-250A light meter with a LI-190R quantum sensor in µmol of photons m-2 s-1.
