In many situations prey choice by predators in the field cannot be established or quantified
using direct observation. The remains of some prey may be visually identified in the guts and …

Molecular analysis of predation, through polymerase chain reaction amplification of prey
remains within the faeces or digestive systems of predators, is a rapidly growing field …

Summary 1 It is not always possible to track trophic interactions between predators and prey
by direct observation. This is especially true when observing small or elusive animals with …

One of the most difficult interactions to observe in nature is the relationship between a
predator and its prey. When direct observations are impossible, we rely on morphological …

Dietary analysis using DNA metabarcoding is a powerful tool that is increasingly being used
to further our knowledge of trophic interactions in highly complex food webs but is not …

Collembola comprise a major source of alternative prey to linyphiid spiders in arable fields,
hel** to sustain and retain these predators as aphid control agents within the crop …

Predation by generalist predators is difficult to study in the field because of the complex
effects of positive and negative interactions within and between predator species and guilds …

DNA‐based techniques are providing valuable new approaches to tracking predator–prey
interactions. The gut contents of invertebrate predators can be analysed using species …

A molecular approach, using aphid‐specific monoclonal antibodies, was used to test the
hypothesis that alternative prey can affect predation on aphids by linyphiid spiders. These …

The soybean aphid, Aphis glycines (Hemiptera: Aphididae), is a pest of soybeans in Asia,
and in recent years has caused extensive damage to soybeans in North America. Within …
