Lack of ¹³C-label incorporation suggests low turnover rates of thaumarchaeal intact polar tetraether lipids in sediments from the Iceland shelf [PDF]

Biogeosciences, 2014
Thaumarchaeota are amongst the most abundant microorganisms in aquatic environments, however, their metabolism in marine sediments is still debated. Labeling studies in marine sediments have previously been undertaken, but focused on complex organic ...

Tissue‐ and diet‐dependent stable carbon and nitrogen isotope discrimination: a calibration study in a captive shorebird species

Journal of Avian Biology, 2023
In ecology, stable‐isotope ratios are widely used to determine diets of organisms and reconstruct food webs. This is usually done by analyzing the stable‐isotope ratios of nitrogen (δ15N), which increase with increasing trophic level, and those of carbon

Lipidomics of Environmental Microbial Communities. II: Characterization Using Molecular Networking and Information Theory

Frontiers in Microbiology, 2021
Structurally diverse, specialized lipids are crucial components of microbial membranes and other organelles and play essential roles in ecological functioning. The detection of such lipids in the environment can reveal not only the occurrence of specific

Hereditary microphthalmia in Texel lambs in Brazil

Small Ruminant Research, 2018
Abstract On a farm in southern Brazil, four lambs in a flock of 300 Texel sheep were born with bilateral blindness. They revealed bilateral occlusion of the eyelids and were unresponsive to external visual stimuli and were disoriented when walking. A post-mortem examination revealed bilateral occlusion of the eyelids and, microscopically, total or ...

Using traits to integrate non‐additive effects of species mixtures across ecosystem processes

Journal of Ecology, EarlyView.
This review shows how to compare the non‐additive effects due to species interactions on different ecosystem processes using similar ‘currency’, and how to link these to the main effects of the same species on these ecosystem processes. This way the species' effects on higher‐level ecosystem functioning (e.g.
