Trophic dynamics and morphometric divergence of coexisting neotropical cichlid species (Teleostei: Cichliformes) in relation to a dam [PDF]

Brazilian Journal of Biology
Freshwater species are under threat from anthropogenic disturbance from in-stream barriers. Trophic interactions are a major driver of community structure and understanding how species partition resources in relation to barriers can help determine ...

Trophic niche overlap between non-indigenous round goby, Neogobius melanostomus, and native fishes in tributaries of the lower Danube River (Bulgaria)

Fisheries & Aquatic Life, 2022
The recent expansion of the round goby (Neogobius melanostomus) in tributaries of the lower Danube (Bulgaria) prompted assessing potential negative effects on local fish fauna such as competition for food resources.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

18S rRNA metabarcoding diet analysis of a predatory fish community across seasonal changes in prey availability

Ecology and Evolution, 2019
Predator–prey relationships are important ecological interactions, affecting biotic community composition and energy flow through a system, and are of interest to ecologists and managers.

Prey preferences and dietary overlap amongst Africa's large predators

South African Journal of Wildlife Research, 2008
Abstract Africa supports Earth's richest assemblage of large predators, which coexist despite a high degree of dietary overlap. This study used reviews of the prey preferences of African wild dog Lycaon pictus, cheetah Acinonyx jubatus, leopard Panthera pardus, lion P. leo, and spotted hyaena Crocuta crocuta to investigate the degree of dietary overlap

Effect of the dietary fat quality on insulin sensitivity. [PDF]

, 2008
Recent evidence shows that specific fatty acids affect cell metabolism, modifying the balance between fatty acid oxidation and lipogenesis. These effects may have important implications in addressing the present epidemic of nutrition-related chronic ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

eDNA metabarcoding reveals dietary niche overlap among herbivores in an Indian wildlife sanctuary

Environmental DNA, 2021
As many ecosystems are under increasing pressure from invasive species, habitat degradation, overgrazing and overharvesting, pollution, and climate change, dietary niche monitoring is gaining importance. The Malai Mahadeshwara Wildlife Sanctuary (MMH) in

Dietary Overlap of an Alien and Native Carnivore on San Clemente Island, California [PDF]

Journal of Mammalogy, 2007
Predation by feral cats (Felis catus) is recognized as a major threat to native fauna worldwide, but the competitive effects of cats on native species have not been extensively studied. Cats occur on San Clemente Island, California, in sympatry with endemic island foxes (Urocyon littoralis clementae).
