Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

New Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

Mass Spectrometry Reviews, Volume 44, Issue 6, Page 1013-1098, November/December 2025.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Quantitative analysis of RNA abondance for CTCF during reprogramming of bovine embryo from oocyte to blastocyst [PDF]

Archives Animal Breeding, 2015
CTCF is a highly conserved protein among eukaryotes and it is involved in many of regulatory functions including, transcriptional repression and activation, chromatin insulation, imprinting, X chromosome inactivation, higher-order chromatin organization,

Associations between soil characteristics and ground‐nesting bees on farms Associations entre les caractéristiques du sol et les abeilles terricoles dans les exploitations agricoles

Insect Conservation and Diversity, Volume 18, Issue 6, Page 1037-1052, November 2025.
We collected ground‐nesting bees at 35 farms over two summers and assessed their abundance, diversity, and community composition in relation to local soil characteristics (texture, compaction, slope, and ground cover). Ground‐nesting bee abundance and species richness increased with bare ground and sand content.

Tuberculose péritonéale : quel outil diagnostique ?

Revue Malienne d’Infectiologie et de Microbiologie, 2014
INTRODUCTION : Le diagnostic de la tuberculose péritonéale reste difficile, surtout dans les pays où la prévalence de la maladie est faible. Malgré l'existence de nombreux moyens diagnostiques peu invasifs, le recours à la cœlioscopie est souvent ...

Abondance de cabillauds en zone VIId [PDF]

, 2008
Depuis la fin de l'année 2007 et le début de l'année 2008, de nombreux professionnels des régions Nord, Haute et Basse Normandie signalent d'importantes captures de cabillaud en Manche Est. De plus, lors de la campagne CGFS (Channel Ground Fish Survey) menée par l’Ifremer en octobre 2007 dans la division VIId du CIEM, les rendements de cabillaud ont ...

Choix d'une unité d'effort de pêche pour les flottilles sardinières sémi-industrielles et artisanales au Sénégal [PDF]

, 1980
Different catches per unit of effort available for industrial and artisanal sardinella fisheries of Senegal have been analysed and compared in order to determine whether they are acceptable indices of abundance.

Calibrating an occupancy metric to monitor elusive territorial species at large scale: Application to the grey wolf population in France

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
As a cost‐effective alternative to abundance, we developed and calibrated a spatial metric to monitor elusive territorial species distributed over large areas. The spatial metric can provide three elements: annual maps of predicted presence, annual estimates of the total area occupied and evaluation of changes in occupancy at a local scale from year to

A generalized modeling framework for spatially extensive species abundance prediction and population estimation

Ecosphere, Volume 16, Issue 10, October 2025.
Abstract Spatially explicit estimates of species abundance and distribution are increasingly needed to support conservation planning and management across multiple spatial scales. We present a generalized modeling framework that bridges the gap between local studies and regional to national planning by compiling and harmonizing diverse datasets to ...
