iDNA from terrestrial haematophagous leeches as a wildlife surveying and monitoring tool - prospects, pitfalls and avenues to be developed [PDF]

, 2015
Invertebrate-derived DNA (iDNA) from terrestrial haematophagous leeches has recently been proposed as a powerful non-invasive tool with which to detect vertebrate species and thus to survey their populations.

Artificial supplementary food influences hedgehog occupancy and activity patterns more than predator presence or natural food availability

Wildlife Biology, EarlyView.
Supplementary feeding for declining hedgehog Erinaceus europaeus populations is popular in Great Britain and has been suggested as an important factor in explaining higher densities in urban areas compared with rural ones. Occupancy modelling was used to test whether spatial variation in supplementary feeding, natural food, habitat, or predator ...

DNA metabarcoding reveals wolf dietary patterns in the northern Alps and Jura Mountains

Wildlife Biology, EarlyView.
Understanding predator–prey interactions is crucial for wildlife management and human–wildlife coexistence, particularly in multi‐use landscapes such as western Europe. As wolves Canis lupus recolonize their former habitats, knowledge of their diet is essential for conservation, management and public acceptance.

Uncovering trophic interactions in arthropod predators through DNA shotgun-sequencing of gut contents [PDF]

, 2016
Characterizing trophic networks is fundamental to many questions in ecology, but this typically requires painstaking efforts, especially to identify the diet of small generalist predators.

Temporal niche partitioning by nocturnal arboreal mammals increases the modularity of plant–frugivore networks in a fragmented subtropical landscape

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animal‐mediated seed dispersal sustains plant diversity and ecosystem functioning, particularly in fragmented landscapes. However, the specific contributions of nocturnal frugivores, particularly in above‐ground (arboreal) strata, are often overlooked, leading to ...

Combined water and detritus sampling is the most effective strategy to detect environmental DNA of macroinvertebrates in rivers

Ecological Indicators
Although environmental DNA (eDNA) metabarcoding technology has been increasingly applied in freshwater ecosystems, the effectiveness of conventional water sampling and other adaptive metabarcoding methods for detecting macroinvertebrates has not been ...

Dietary resilience of coral reef fishes to habitat degradation

Journal of Animal Ecology, EarlyView.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Evaluation and application of eDNA metabarcoding primers of fish: A case study in an estuarine ecosystem

Global Ecology and Conservation
The selection of primers is crucial for conducting eDNA metabarcoding studies, particularly in estuarine regions characterized by complex habitats and high fish diversity. However, most previous eDNA metabarcoding studies have not systematically screened

Evaluating Prey Availability for the Rice's Whale (<i>Balaenoptera ricei</i>) Based on Environmental DNA. [PDF]

Ecol Evol
To characterize the prey community of the critically endangered Rice's whale, we employed environmental DNA (eDNA) metabarcoding in its core habitat. Our multi‐marker approach detected significantly greater fish biodiversity than concurrent trawl surveys and revealed a higher prevalence of key prey taxa.

Quantifying uncertainty of taxonomic placement in DNA barcoding and metabarcoding [PDF]

, 2017
A crucial step in the use of DNA markers for biodiversity surveys is the assignment of Linnaean taxonomies (species, genus, etc.) to sequence reads. This allows the use of all the information known based on the taxonomic names. Taxonomic placement of DNA
