Generation and Maintenance of Diversity in an Island: A History of Fragmentation, Secondary Contact and Admixture

open access: yesJournal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Aim To gain detailed insights into how vertebrate intraspecific diversity can be generated and maintained within volcanic islands, using genomic data. Location The Canary Islands of Tenerife and La Palma. Time Period Tissue samples were obtained in 2003. Genomic analyses were performed in 2023–25. Taxon The endemic gecko, Tarentola delalandii.

Do Island Spiders Descend From Trees? – A Tale of Island Colonisation and Niche Expansion

open access: yesJournal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim Oceanic islands are known for being home to drastically different communities compared to the mainland, as their isolation and limited area significantly favour clades able to travel long distances over water. On spiders, this happens mainly, although not exclusively, through ballooning whose propensity is unevenly distributed across ...

Molecular Delimitation of Evolutionary Significant Units Reveals Hidden Geographic Drivers of Extinction Risk Within Island Arthropods

open access: yesDiversity and Distributions, Volume 31, Issue 1, January 2025.
ABSTRACT Aim Globally, arthropod biodiversity is under threat, with increased risk of species‐level extinctions, and this threat is particularly acute on oceanic islands. A fundamental first step towards understanding extinction risk is to understand genetic connectivity among the constituent populations of a species.

In defence of the entity of Macaronesia as a biogeographical region

open access: yesBiological Reviews, Volume 99, Issue 6, Page 2060-2081, December 2024.
ABSTRACT Since its coinage ca. 1850 AD by Philip Barker Webb, the biogeographical region of Macaronesia, consisting of the North Atlantic volcanic archipelagos of the Azores, Madeira with the tiny Selvagens, the Canaries and Cabo Verde, and for some authors different continental coastal strips, has been under dispute. Herein, after a brief introduction

Genetic legacies of mega‐landslides: Cycles of isolation and contact across flank collapses in an oceanic island

open access: yesMolecular Ecology, Volume 33, Issue 9, May 2024.
Abstract Catastrophic flank collapses are recognized as important drivers of insular biodiversity dynamics, through the disruption of species ranges and subsequent allopatric divergence. However, little empirical data supports this conjecture, with their evolutionary consequences remaining poorly understood.
