title: Data from: A meta-analysis of non-consumptive predator effects in arthropods: the influence of organismal and environmental characteristics

description: Non-consumptive effects (NCEs) – changes in prey behavior or physiology in
 response to predator threat – are common and can be as strong as
 consumptive effects. However, our knowledge of NCEs in arthropod systems
 is lacking. Factors related to study organism and environment have the
 potential to influence the occurrence and magnitude of NCEs in arthropod
 systems. While factors such as coevolutionary history of natural enemies
 and their prey, predator cue, predator or prey feeding mode, and refuge
 availability have been theoretically and empirically examined, no trends
 have been proposed for arthropods. We compiled 62 studies, yielding 128
 predator–prey interactions, which explicitly examined NCEs in experiments
 where arthropods were identified to species, using a previously published
 database of papers from 1990 to 2005 and a new database of papers
 published from 2006 to 2015. Using these data, we conducted a
 meta-analysis to explore the influence of organismal and environmental
 characteristics on the magnitude of predator NCEs. Our analysis addressed
 the following three questions. 1) Does predator–prey coevolution give rise
 to stronger NCEs than when predator and prey species did not coevolve? 2)
 What influence does habitat type and refuge availability have on NCEs? 3)
 How do predator characteristics (cue type, hunting mode and life stage)
 and prey characteristics (mobility, life stage, specialization,
 gregariousness and feeding mode) influence NCEs? We found that while NCEs
 were similar across most measured characteristics, NCEs on prey activity
 were significantly stronger when predator and prey shared an evolutionary
 history. Our results support growing evidence that NCEs have a negative
 effect on prey traits and that behavioral NCEs are stronger than
 physiological ones. Additional studies are needed to be confident in any
 emerging patterns, therefore we identify key gaps in the literature on
 NCEs in arthropod systems and discuss ideas for moving forward.

 al_Oikos_Metaanalysis dataThis data file is an
 excel file containing three worksheets. (1) "Table of contents"
 defines the column names for the remaining worksheets; (2) "Data
 extracted from papers" contains values and descriptors for each
 non-consumptive effect response for each of the 62 papers used in the
 analysis. Descriptors include information about the paper (e.g., type of
 study, where in the paper the data was found) and the study species used
 in the paper (e.g., species names and characteristics); (3)
 "Collapsed data and effect sizes" contains the same descriptors
 as worksheet (2), but also includes (i) effect sizes (log response ratios)
 and variance as calculated by MetaWin , and (ii) values averaged within a
 single paper where inclusion of multiple separate data points from a
 single paper would have resulted in psuedoreplication. Data contained in
 worksheet (3) "Collapsed data and effect sizes" is the data used
 in the meta-analysis and reported in the manuscript.
