Article Abstract
The Azores, Madeira, Selvagens, Canary Islands and Cabo Verde are commonly united under the term "Macaronesia". This study investigates the coherency and validity of Macaronesia as a biogeographic unit using six marine groups with very different dispersal abilities: coastal fishes, echinoderms, gastropod molluscs, brachyuran decapod crustaceans, polychaete annelids, and macroalgae. We found no support for the current concept of Macaronesia as a coherent marine biogeographic unit. All marine groups studied suggest the exclusion of Cabo Verde from the remaining Macaronesian archipelagos and thus, Cabo Verde should be given the status of a biogeographic subprovince within the West African Transition province. We propose to redefine the Lusitanian biogeographical province, in which we include four ecoregions: the South European Atlantic Shelf, the Saharan Upwelling, the Azores, and a new ecoregion herein named Webbnesia, which comprises the archipelagos of Madeira, Selvagens and the Canary Islands.

is a phytophagous insect widely distributed across Asia, Europe, and Africa, yet its genetic variation remains poorly understood. This study presents the first comprehensive analysis of the genetic diversity and structure of in Thailand using mitochondrial cytochrome c oxidase subunit 1 () sequences from 202 individuals across 27 localities. A total of 58 haplotypes were identified, with high haplotype and nucleotide diversity observed, suggesting substantial genetic variation.

Thus, it is biogeographically unique due to its specialised anatomy and biology as a volant rodent. As a result of habitat fragmentation and destruction, Siberian flying squirrels experience severe and ongoing population declines throughout most of their distribution.

Disjunct distribution patterns have long intrigued biogeographers, sparking ongoing debates about the mechanisms driving the current distribution of biodiversity. Among the most discussed patterns are long-distance dispersal and vicariance. While these patterns have been extensively studied in plants, marine taxa, mammals, and some invertebrates, they remain less explored in groups like moths.

Microbial strains within a single species can exhibit distinct functional characteristics due to variations in gene content and often show individual specificity, which can obscure unbiased associations and hinder deductive research. Here, we comprehensively define the human gut microbiota at a consistently annotated operational subspecies unit (OSU) resolution in an unbiased, cohort-independent manner, demonstrating that this approach can generalize across diverse global populations while maintaining specificity and improving interstudy reproducibility. We develop panhashome-a sketching-based method for rapid subspecies and species quantification and identification of genes that drive intraspecies variations-and show that subspecies carry implicit information undetectable at the species level.

Alpine treeline is a prominent biogeographic feature worldwide, determined by the physiological limit of tree life form. There are considerable variations in the various dimensions of physiological limit among tree taxa; thus, varied environmental drivers and spatial patterns are expected for different tree taxa at treelines. However, such taxonomic variability of treeline is often overlooked in large-scale studies.
