Abyssal deposit feeders are secondary consumers of detritus and rely on nutrition derived from microbial communities in their guts

Scientific Reports, 2021
Trophic ecology of detrital-based food webs is still poorly understood. Abyssal plains depend entirely on detritus and are among the most understudied ecosystems, with deposit feeders dominating megafaunal communities.

Historical niche partitioning and long‐term trophic shifts in Laurentian Great Lakes deepwater coregonines

Ecosphere, 2018
Over the last 100 yr, anthropogenic stressors have decimated the assemblage of deepwater coregonines that once underpinned the food webs of the Laurentian Great Lakes.

Regional Variation in the Trophic Ecology of Wahoo (Acanthocybium solandri) in the Western Atlantic Ocean

Fishes, 2023
Intrinsic tracers, such as stable isotopes of carbon and nitrogen, are common dietary markers that accumulate in the muscle tissue of consumers and can be used to determine the dietary sources and trophic positions of consumers. The aim of this study was

Network-Based Biomonitoring: Exploring Freshwater Food Webs With Stable Isotope Analysis and DNA Metabarcoding

Frontiers in Ecology and Evolution, 2019
Threatened freshwater ecosystems urgently require improved tools for effective management. Food web analysis is currently under-utilized, yet can be used to generate metrics to support biomonitoring assessments by measuring the stability and robustness ...

Understanding patterns and processes in models of trophic cascades [PDF]

, 2013
Climate fluctuations and human exploitation are causing global changes in nutrient enrichment of terrestrial and aquatic ecosystems and declining abundances of apex predators. The resulting trophic cascades have had profound effects on food webs, leading

Polyunsaturated fatty acids in fishes increase with total lipids irrespective of feeding sources and trophic position

Ecosphere, 2017
Trophic transfer and retention of dietary compounds are vital for somatic development, reproduction, and survival of aquatic consumers. In this field study, stable carbon and nitrogen isotopes, and fatty acids (FA) contents in invertebrates and fishes of

Impacts of intensive logging on the trophic organisation of ant communities in a biodiversity hotspot. [PDF]

PLoS ONE, 2013
Trophic organisation defines the flow of energy through ecosystems and is a key component of community structure. Widespread and intensifying anthropogenic disturbance threatens to disrupt trophic organisation by altering species composition and relative

A missing trophic link: Contribution of the microbial loop to the estimation of the trophic position of pelagic consumers

, 2023
Trophic position estimation has been a central issue in food web studies. Estimates using compound-specific isotopic analyses of amino acids were generally based on the trophic enrichment of glutamic acid. However, this trophic position estimation mainly

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
