The Single, the Whole, and the Pooled: Implications of Tissue Choice for Stable Isotope Analysis. [PDF]

J Exp Zool A Ecol Integr Physiol
ABSTRACT In the exciting era of non‐invasive tissue sampling and data reuse via open access databases, it is increasingly challenging to ensure comparability of sample types for stable isotope analysis in ecology. According to the theoretical predictions about the changes in the stable isotope values between prey and consumers and tissue turnover rates,

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

Fisheries Oceanography, EarlyView.
ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

Ibis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...

Combining eDNA metabarcoding and stable isotope analysis advances diet studies in a colonial, non‐regurgitating seabird

Ibis, EarlyView.
Understanding seabird diet is fundamental to assessing trophic interactions and predicting responses to environmental change. However, seabird diet studies are often constrained by low taxonomic resolution, invasive sampling methods or reliance on opportunistically collected samples, leaving the diet of important populations such as Common Guillemots ...

Hypercapnia Induces Mitochondrial Adaptations and Alters Glutamine Metabolism to Drive a Distinct Metabolic Phenotype in Monocytes

Immunology &Cell Biology, EarlyView.
Elevated CO2 (hypercapnia) is a feature of serious lung diseases, for example COPD and contributes to poor patient prognosis through modulation of immune cell function. Here we employ state‐of‐the art metabolomic and isotope tracing approaches to reveal CO2‐dependent mitochondrial alterations linked to suppressed ATP, proline and glutamate levels in ...
