CAMELIA: Enhancing species assemblage predictions by integrating structural and functional indices: A case study on plant communities in the French Alps

Methods in Ecology and Evolution, Volume 16, Issue 11, Page 2694-2709, November 2025.
Abstract Addressing the challenge of predicting biodiversity requires models that fully capture the complex dynamics of species and communities. While species distribution models (SDMs) predict individual species' distributions based on environmental variables, they often fail to reconstruct realistic communities.

Facteurs écologiques impactant les communautés végétales ligneuses et herbacées des parcours du Ferlo entre 1970 et 1981 [PDF]

, 2017
Les parcours sahéliens sont peuplés d'une communauté d'herbacées principalement annuelles en interaction avec une communauté de ligneux. Le lien statistique entre la composition botanique des communautés ligneuses et celle des herbacés est étudié.

Genetic Rescue in Action: Long‐Term Monitoring Reveals Admixture‐Driven Fitness Gains in a Translocated Plant

Conservation Letters, Volume 18, Issue 6, November/December 2025.
ABSTRACT Mixed‐source translocation can reduce immediate extinction risk by increasing population size, genetic diversity, and individual fitness, but their long‐term consequences remain debated. To rescue the perennial plant Arenaria grandiflora from extinction in the Fontainebleau Forest (northern France), local and non‐local (Chinon, Central France)

Relation entre la composition botanique de végétations de montagne et leur composition en composés volatils

, 2000
In order to find objective data linking the quality of cheese to environmental conditions, we studied the relationships between the botanical composition of various mountain pastures and the contents of volatile compounds in the plants ; the idea was to understand how these compounds could influence the organoleptic properties of cheese. Ten samples of

Beyond similarity: A network approach for identifying and delimiting biogeographical regions [PDF]

, 2014
Biogeographical regions (geographically distinct assemblages of species and communities) constitute a cornerstone for ecology, biogeography, evolution and conservation biology.

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

Population Ecology, Volume 67, Issue 4, Page 310-335, October 2025.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

Evolutionary rescue in a mixed beech–fir forest: insights from a quantitative‐genetics approach in a process‐based model

Oikos, Volume 2025, Issue 10, October 2025.
Questions have been raised about the ability of long‐lived organisms, such as trees, to adapt to rapid climate change, and to what extent forest management actions influence the evolutionary responses of tree species. Given the life history of trees and the time scales involved, these questions are often addressed through modeling approaches. Yet, most

Important Habitat for Chimpanzees in Mali [PDF]

, 2000
Analysis of botanical data is presented from the standpoint of chimpanzee natural history. The Sudano-Guinean gallery forest type dominated by the tree Gilletiodendron glandulosum appears to be important habitat for chimpanzees due to vegetation ...

A Multi-level Blocking Distinct Degree Factorization Algorithm [PDF]

, 2007
We give a new algorithm for performing the distinct-degree factorization of a polynomial P(x) over GF(2), using a multi-level blocking strategy. The coarsest level of blocking replaces GCD computations by multiplications, as suggested by Pollard (1975 ...
