Assessing spider diversity in grasslands – does pitfall trap color matter? has been accepted in Journal of Arachnology.
Authors Möller M & Buchholz S
We analyzed effects of pitfall trap color (white, yellow, green, brown) on spider catches and found differences in alpha-diversity and one biological trait, namely hunting type. Attractiveness of different trap colors may arise due to differences in biological preconditions, albedo and microclimate which in turn can affect diversity and community structure of spiders. Trap color has a significant impact on spider catches and should be considered when planning surveys.
