Variations in the Stable Carbon Isotopic Composition of Soil Organic Matter in Mountain Depressions of the Cis-Baikal Region
AbstractDepth-profile and spatial variations of the stable carbon isotopic composition of soil organic matter is analyzed to identify the main...

Fatty acid isotopic composition in Atlantic pollock is not influenced by environmentally relevant dietary fat concentrations
The application of fatty acid (FA) isotopic analysis has great potential in elucidating food web structure, but it has not experienced the same...

Controls on the Carbon Isotopic Compositions of Lipids in Marine Environments
Organic carbon isotopes have long been used to study modern and ancient biogeochemical processes. Controls on the isotopic composition of organic... -
The Use of Isotopic Differences of Carbon Fractions of Biomass in Plants to Study Transport Flows and Source–Sink Relations under Different Light Conditions
AbstractIt is shown that the differences water-soluble and water-insoluble fractions of plant leaf biomass, as well as phloem, are evolutionarily...

Spatial distribution and stable isotopic composition of invertebrates uncover differences between habitats on the glacier surface in the Alps
Glacier surfaces are the most biologically productive parts of glaciers with a variety of organisms and habitats. However, distinctiveness of...

Isotopic Tracers of the Marine Nitrogen Cycle: Present and Past
The oceanic nitrogen cycle consists of a web of microbially mediated transformations driven in part by the large range in possible nitrogen... -
Tree-ring isotopic composition reveals intraspecific variation in water use efficiency of Pinus pinaster Ait. provenances grown in common gardens
Key messageThe physiological responses expressed by variation in carbon and oxygen stable isotopes and iWUE in five provenances of maritime pine...

Ontogenetic variation in isotopic niche positions of aquatic consumers in boreal lakes
We used an extensive multispecies dataset to examine how C and N stable isotope ratios (δ 13 C and δ 15 N) of aquatic consumers varied with body size in...

Human habitat modification, not apex scavenger decline, drives isotopic niche variation in a carnivore community
Top carnivores can influence the structure of ecological communities, primarily through competition and predation; however, communities are also...

Isotopic niche partitioning in a multi-species assemblage
Multi-species assemblages can help identify key resources in their habitat by evaluating how they are partitioning their resources. Here we used the...

Disentangling Diel Variations in the Carbon Isotopic Composition of Soil CO2 Efflux: Insights from a Multi-chamber System and a Non-Steady-State Model
Soil carbon dioxide (CO 2 ) efflux ( F s ) and its carbon isotopic composition ( δ Fs ) based on the chamber methods are widely used to represent soil...

The decadal variability of elemental, isotopic, and biochemical compositions of coastal Mediterranean zooplankton responds to environmental changes
The functioning of Mediterranean coastal waters is deeply affected not only by global environmental changes (e.g., global warming, climate change)...

Isotopic Variability in Bone Collagen of Short-Tailed Albatrosses (Phoebastria albatrus) in the Bering Sea Area during the Holocene
The short-tailed albatross ( Phoebastria albatrus ) is a rare bird species today, numbers of which declined significantly in the Holocene due to human...

Plant Competition Across Topographic Gradients in Neotropical Cerrado Savannas: An Isotopic Approach
The Cerrado is the second most extensive biome in South America, encompassing a series of plant physiognomies, which normally form gradients of tree... -
Isotopic evidence of high reliance on plant food among Later Stone Age hunter-gatherers at Taforalt, Morocco
The transition from hunting-gathering to agriculture stands as one of the most important dietary revolutions in human history. Yet, due to a scarcity...

Isotopic diversity and niche patterns reveal contrasting resource use among co-occurring non-native fishes within a flow-altered African river system
Classic and contemporary trophic ecology-based studies have shown that most non-native freshwater fish species (NNS) that integrate into novel...

Intra- and inter-individual changes in little penguin diving and isotopic composition over the breeding season
Seabirds allocate different amounts of energy to reproduction throughout the breeding season, depending on the trade-off between their own needs and...

What a sucking louse can tell us: the use of the seal lice (Lepidophthirus macrorhini) from the southern elephant seal (Mirounga leonina) in isotopic analysis of hosts
The southern elephant seal, Mirounga leonina , is one of the top predators inhabiting the Southern Ocean. Foraging at sea represents 80% of their...

The Influence of Wavelengths of Different Ranges of Photosynthetically Active Radiation on the Carbon Isotope Composition of Plant Biomass and Its Fractions (Using the Lettuce (Lactuca sativa L.) Cultivar Aficion as an Example)
AbstractThe influence of incident wavelengths of four ranges—short-wave red (623–641 nm), long-wave red (646–667 nm), far red (727–751 nm), and blue...
