WebJan 21, 2024 · Predator–prey interactions shape ecosystems and can help maintain biodiversity. However, for many of the earth's most biodiverse and abundant organisms, including terrestrial arthropods, these interactions are difficult or impossible to observe directly with traditional approaches. WebPreliminary evidence also indicates flower species may impact the amount of arthropod eDNA that can be detected. We found that eDNA metabarcoding can provide clues to potential predator–prey interactions on flowers and highlights the potential insights that can be gained from future eDNA metabarcoding studies. WebPrey instead reduce the likelihood of an interaction with an active hunting predator by being reciprocally wide-roaming or settling into a reliable refuge. Unlike active hunters, ambush hunters stay in one location until prey pass within attack distance, meaning their cues are overall more reliable as an indicator of risk, and may additionally convey a high level of risk. aspen 1 motala
