Title All Arrays Seed Packets and fungi_for Dryad
Downloaded 13 times
Description All Arrays Seed Packets and fungi_for Dryad.txt This datafile includes the numbers and sizes of protocorms recovered from seedpackets placed at varying distances from conspecific plants and the abundance of fungi associated with those seedpackets. Missing data are indicated by a “.”. Data were collected by Melissa McCormick, Robert Burnett, and Dennis Whigham. Questions should be directed to Melissa McCormick. Column headings Species: The orchid species of seeds added to the plot in seedpacket. Goodyera=Goodyera pubescens; Liparis=Liparis liliifolia; Tipularia=Tipularia discolor Plot: Designates which of the arrays (e.g., BPLg) seed packets were recovered from. The array names also indicate whether the array was associated with a cluster of plants, in which case it ends in ‘Lg’, or an isolated plant, in which case the name ends in ‘i’. The plots were in forest stands that ranged from 70 to 150 years old at the Smithsonian Environmental Research Center, Edgewater, Maryland, USA. Distance: Indicates the distance (in cm) from the seedpacket to the nearest conspecific plant. Direction: Indicates which ‘arm’ of the array the seed packet was located on. ‘Arms’ were oriented based on cardinal directions and are noted as n=north, s=south, e=east, w=west. Protocorms: Indicates the number of protocorms recovered from each seedpacket. Size (mm): Indicates the size in mm of the largest protocorm found in each seedpacket. A ‘.’ indicates no protocorms were recovered from a seedpacket. Fungus Abundance: Indicates the abundance of appropriate mycorrhizal fungi in the soil associated with each seedpacket. Abundance is noted as 0=absent or 1-5=present, with 5 indicating the greatest abundance and 1 the least. Abundance was measured semi-quantitatively from the sum of ARISA peak heights for two microsatellite primers (Goodyera) or the brightness of gel bands using taxon-specific primers (Liparis, Tipularia).
