Ecological scale mediates nonlinear relationships of animal nutrient excretion with dissolved organic matter

Journal of Animal Ecology, EarlyView.
We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Plant genetic and root‐associated microbial diversity modulate Lactuca sativa responsiveness to a soil inoculum under phosphate deficiency

New Phytologist, EarlyView.
Leaf phosphate and shoot biomass variation in response to the microbial consortium. Summary Microbial‐based approaches offer a promising strategy to decrease the use of chemical fertilizers in agriculture. Among them, arbuscular mycorrhizal fungi (AMF), which extend root surface area and enhance phosphate uptake, and phosphate‐solubilizing bacteria ...

Chemical Composition of the Essential Oil from Corsican Combined Analysis by GC(RI), GC-MS and C NMR Spectroscopy

Natural Product Communications, 2011
The essential oil (EO) of M. aquatica L. growing wild in Corsica was isolated by dry vapor distillation and submitted to combined analysis by column chromatography over silica gel, GC(RI), GC-MS and 13 C NMR spectroscopy. The composition was dominated by

Phenolic composition and multi‐target bioactivities of Globularia alypum extracts across seasons

JSFA reports, Volume 6, Issue 8, Page 314-330, August 2026.
Abstract Background This study investigates the influence of seasonal variation on the phytochemical profile and biofunctional activities of ethanolic leaf extracts from Globularia alypum. Leaves collected across four seasons were extracted with a hydroethanolic solvent (80:20, v/v) and analyzed by LC‐ESI‐MS/MS.

Composition and Chemical Variability of the Leaf Oil from Corsican Integrated Analysis by GC(RI), GC-MS and C NMR

Natural Product Communications, 2010
The composition of 16 samples of leaf oil from Corsican Juniperus thurifera was investigated by integrated techniques, GC, GC-MS and 13 C NMR. K-means partitioning and PCA analysis of the data allowed the definition of a main group (14 samples) dominated
