Data from: Compared with conventional PCR assay, qPCR assay greatly improves the detection efficiency of predation

Ting-Bang Yang, Jie Liu & Jian Chen
Studies of predation can contribute greatly to understanding predator-prey relationships and can also provide integral knowledge concerning food webs and multi-trophic level interactions. Both conventional polymerase chain reaction (cPCR) and quantitative PCR (qPCR) have been employed to detect predation in the field because of their sensitivity and reproducibility. However, to date, few studies have been used to comprehensively demonstrate which method is more sensitive and reproducible in studies of predation. We used a Drosophila melanogaster-specific...

Detritus decorations as the extended phenotype deflect avian predator attack increasing fitness in an orb‐web spider

A number of strategies that divert attacks of visually guided predators, such as birds, have evolved multiple times in animals. Detritus web decorations built by certain orb-web spider species are thought to deflect avian predator attacks away from spiders and towards their web decorations. Still, empirical evidence for this function and its adaptive significance is lacking. The orb-web spider, Cyclosa monticola, adorns its web using a linear detritus decoration consisting of moults, egg sacs, prey...
