Quantifying the Dietary Overlap of Two Co‐Occurring Mammal Species Using DNA Metabarcoding to Assess Potential Competition [PDF]

Ecology and Evolution
Interspecific competition is often assumed in ecosystems where co‐occurring species have similar resource requirements. The potential for competition can be investigated by measuring the dietary overlap of putative competitor species.

Stable isotope ecology and interspecific dietary overlap among dolphins in the Northeast Atlantic

Frontiers in Marine Science, 2023
Dolphins are mobile apex marine predators. Over the past three decades, warm-water adapted dolphin species (short-beaked common and striped) have expanded their ranges northward and become increasingly abundant in British waters.

Prey size is more representative than prey taxa when measuring dietary overlap in sympatric forest bats

Environmental DNA, 2022
In temperate forests, insectivorous bats need to use variable hunting strategies as prey availability fluctuates during the growing season. At sites with variable amounts of forested habitat, sympatric bat species may exhibit high dietary overlap, but ...

Associations between diet quality, epigenetic aging and epigenome in two population-based cohorts [PDF]

Nature Communications
Several dietary patterns have been associated with better health outcomes. However, the extent to which adherence to different so-called healthy diets overlaps, whether these dietary patterns are equally beneficial, and whether they are associated with ...

Patterns of dietary niche breadth and overlap are maintained for two closely related carnivores across broad geographic scales

Frontiers in Ecology and Evolution, 2022
Ecological studies investigating niche breadth and overlap often have limited spatial and temporal scale, preventing generalizations across varying environments and communities.

Diet Metabarcoding Reveals Extensive Dietary Overlap between Two Benthic Stream Fishes (Zingel asper and Cottus gobio) and Provides Insights into Their Coexistence

Diversity, 2022
Niche partitioning studies are essential to understand the mechanisms that allow ecologically similar species to coexist. The Rhone streber (Zingel asper) and the European bullhead (Cottus gobio) are both benthic riverine fishes that consume ...

Summer Diet of Horses (Equus ferus caballus Linn.), Guanacos (Lama guanicoe Müller), and European Brown Hares (Lepus europaeus Pallas) in the High Andean Range of the Coquimbo Region, Chile

Animals, 2021
For an adequate management of natural grasslands, the knowledge and understanding of the dietary habits of herbivores and their trophic interactions are fundamental. During two summer seasons, in a mountain range of a sector of the Coquimbo Region, Chile,

Niche partitioning by sympatric civets in the Himalayan foothills of Pakistan [PDF]

PeerJ, 2023
Niche overlap between sympatric species can indicate the extent of interspecific competition. Sympatric competing species can exhibit spatial, temporal, and dietary adjustments to reduce competition.

Domestic Cattle in a National Park Restricting the Sika Deer Due to Diet Overlap

Animals, 2023
Managers need to know the extent of the conflict between livestock and wild animals. Although many studies have reported the conflict between livestock and wild animals, few have checked the extent of the conflict.

Seasonal and ontological variation in diet and age‐related differences in prey choice, by an insectivorous songbird

Ecology and Evolution, 2022
The diet of an individual animal is subject to change over time, both in response to short‐term food fluctuations and over longer time scales as an individual ages and meets different challenges over its life cycle.
