PleistoDist: A toolbox for visualising and quantifying the effects of Pleistocene sea‐level change on island archipelagos

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 2, Page 496-504, February 2023., 2023
Abstract Pleistocene sea‐level change played a significant role in the evolution and assembly of island biotas. The formation of land bridges between islands during Quaternary glacial maxima, when sea levels were more than 120 metres below present‐day sea levels, often facilitated historical dispersal and gene flow between islands that are today ...

An analytically derived delineation of the West African Coastal Province based on bivalves

open access: yesDiversity and Distributions, Volume 28, Issue 12, Page 2791-2805, December 2022., 2022
Abstract Aim To assess the pattern of biotic regions (BR) and their boundaries, to detect chorotypes and to relate these patterns to key environmental factors. Location Eastern Atlantic Ocean. Time period Recent. Taxon studied Bivalvia. Methods Distributions were scored for 595 species. Operational geographical units are classified hierarchically using

Origin of the central European steppe flora: insights from palaeodistribution modelling and migration simulations

open access: yesEcography, Volume 2022, Issue 12, December 2022., 2022
The biogeographic origin of the species‐rich steppe grasslands in central Europe has long been debated. The alternative hypotheses are long‐term species persistence in situ versus immigration from the south‐east, either after the last glacial maximum (LGM) or after the Neolithic landscape deforestation.

Hay meadows' overriding effect shapes ground beetle functional diversity in mountainous landscapes

open access: yesEcosphere, Volume 13, Issue 8, August 2022., 2022
Abstract Mountain regions are hotspots of biodiversity, and are particularly sensitive to human activities and global changes. Characterizing biodiversity using trait‐based approaches may improve the understanding of the evolutionary and mechanistic basis of ecological patterns in species distribution.

Longitudinal vegetation turnover in an eastern Rift Valley riparian corridor

open access: yesAfrican Journal of Ecology, Volume 60, Issue 1, Page 27-42, March 2022., 2022
Abstract East African riparian corridors are biodiversity hot spots that occur in catchments degrading under deforestation and overgrazing. Quadrats and belt transects were employed to investigate plant succession along the River Gilgil, in the Kenyan Rift Valley. The study found that most species (total 365) were broadly distributed across the tropics,

Phytosociological survey of the desert vegetation of Sinai, Egypt

open access: yesApplied Vegetation Science, Volume 24, Issue 4, October/December 2021., 2021
For the first time, we present a syntaxonomy of Sinai desert vegetation, and its phytosociology. We compiled a comprehensive database and applied different analyses to it. We found nine classes: Salicornietea fruticosae, Retametea raetam, Haloxylonetea salicornici, Retamo‐Tamaricetea fluviatilis, Acacietea tortilis, Artemisietea herbae‐albae ...

On the concept of chorotype [PDF]

open access: yesJournal of Biogeography, 2015
AbstractRecent reviews of the meaning of the word ‘chorotype’ in biogeography have led to contrasting definitions and a confusion of concepts. This is because ‘chorotype’ has been used by different authors to express two different concepts: (1) groups of species with overlapping ranges (overall distributions) and (2) groups of species with a similar ...

Le chorotype de l’estuaire européen

open access: yesMappemonde, 1995
Les grands estuaires européens sont des territoires complexes. Cette complexité est liée à la rupture entre les espaces maritime et continental ; ce sont donc des lieux d’enjeux et de conflits pour les divers acteurs qui structurent leur territoire.
