By depicting who eats whom, food webs offer descriptions of how grou**s in nature
(typically species or populations) are linked to each other. For asking questions on how food …

Introduction The PCR-based analysis of homologous genes has become one of the most
powerful approaches for species detection and identification, particularly with the recent …

Research in ecology and wildlife biology remains crucial for increasing our knowledge and
improving species management and conservation in the midst of the current biodiversity …

Food webs in agricultural systems are complex and trophic linkages are difficult to track
using conventional methodologies. Here, we review three alternative approaches that allow …

DNA metabarcoding of food in animal scats provides a non‐invasive dietary analysis
method for vertebrates. A variety of molecular approaches can be used to recover dietary …

Predicting whether a predator is capable of affecting the dynamics of a prey species in the
field implies the analysis of the complete diet of the predator, not simply rates of predation on …

Dietary and predator–prey studies are more frequently relying on DNA metabarcoding
methods, typically achieving results that have a better taxonomic resolution (eg, species …

The Adélie penguin is the most important animal currently used for ecosystem monitoring in
the Southern Ocean. The diet of this species is generally studied by visual analysis of …

The study of marine coastal food webs has a central role in the application of the integrated
ecosystem approach for marine management. Changes in food webs caused by natural or …

To understand the ecosystem dynamics that underpin the year-round presence of a large
generalist consumer, the Bryde's whale (Balaenoptera edeni brydei), we use a DNA …
