Title Spider Abundance
Downloaded 2 times
Description Spider abundances for the three studied species (Dictyna, Aculepeira, and Tetragnatha) across three sites on simulated invasion and control plots. Spider abundance was observed three times each year (June, July, August) over the two-year study (2011-2012).

Title Spider Mechanisms
Downloaded 1 time
Description Potential mechanisms (web size, prey captures, and reproduction) leading to web spider community reassembly following Centaurea stoebe invasion. These mechanisms were experimentally evaluated in three focal web spider species (Dictyna, Aculepeira, Tetragnatha) over two summers (2011-2012) across three sites by comparing responses on simulated invasion and control plots.

Title Web size 2011
Downloaded 2 times
Description Web sizes for Dictyna and Aculepeira across three sites over three sampling periods (June, July, August) in 2011. These data were used to evaluate if web size differed temporally and to justify pooling of web size data within a given year.

Title Juveniles 2012
Downloaded 1 time
Description The number of juvenile spiders (Dictyna, Aculepeira) observed across three sites on simulated invasion and control plots during 2012. These data were used to calculate recruitment (= # juveniles present in August 2012 / # reproductive females June 2012).

Title Prey abundance 2012
Downloaded 1 time
Description Invertebrate prey was sampled via sweep netting in July 2012. These data show the total number of invertebrate prey per sweep net sample at three sites on simulated invasion and control plots. These data were used to evaluate the amount of available prey between plots.
