First insight of genetic diversity, phylogeographic relationships, and population structure of marine sponge Chondrosia reniformis from the eastern and western Mediterranean coasts of Tunisia

Ecology and Evolution, 2022
Despite the strategic localization of Tunisia in the Mediterranean Sea, no phylogeographic study on sponges has been investigated along its shores. The demosponge Chondrosia reniformis, descript only morphologically along Tunisian coasts, was chosen to ...

Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, Volume 55, Issue 5, Page 681-692, September 2026.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Considerations and distributional innovations for some taxa of the genus Parapholis (Poaceae) in the Adriatic basin with special reference to Parapholis strigosa, for which a new infraspecific taxon is proposed

Natural History Sciences
The distribution of Parapholis strigosa (Dumort.) C.E.Hubb. in the Adriatic basin has been analysed. After the investigations by Hylander and Runemark, further collections were made, particularly during the years 1991-2002, and in 2017-2018 limited to ...

A novel taxon selection method, aimed at minimizing recombination, clarifies the discovery of a new sub‐population of Helicobacter pylori from Australia

Evolutionary Applications, 2020
We present a novel method for taxon selection, the aim being to minimize problems arising from highly recombinant species such as Helicobacter pylori.

Spatial metrics in fire ecology: seeking consistency amidst complexity

Biological Reviews, Volume 101, Issue 4, Page 1641-1661, August 2026.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Plant Taxonomy, Systematics and Phylogeography

Plants
Plant taxonomy and phylogeny deal with very important problems related to the genetic diversity of populations found in different geographical regions, trying to present the variability of these populations but also to explain their origin.

Mito‐Nuclear Discordance and Species Boundaries in the Freshwater Fish Genus Cyprinion Revealed by Genome‐Wide SNPs

Ecology and Evolution, Volume 16, Issue 8, August 2026.
The cyprinid genus Cyprinion exhibits complex and contentious species boundaries across western Asia due to extensive morphological overlap and shallow mitochondrial divergence. Using integrated COI and genome‐wide SNP analyses, we identified distinct genomic clusters among several taxa despite shared mitochondrial haplotypes, revealing signatures of ...

Testing the Rio Doce as a riverine barrier in shaping the Atlantic rainforest population divergence in the rodent Akodon cursor

Genetics and Molecular Biology, 2010
Akodon cursor occurs in dense rainforest from northern (8º S) to southern (26º S) states along the Atlantic coast of Brazil. Previous karyological and molecular data revealed two major clades, one including northern (8-15º S) and the other southern (19 ...

The Complete Mitochondrial Genome and Phylogenetic Position of the Pacific Spiny Dogfish Squalus suckleyi (Squaliformes: Squalidae)

Ecology and Evolution, Volume 16, Issue 8, August 2026.
The Pacific spiny dogfish (Squalus suckleyi) is a North Pacific shark of conservation consern that until now lacked a complete mitochondrial genome. We report its first mitogenome (16,738 bp; 37 genes), assembled from PacBio HiFi reads and recover it as sister to S.

Candida auris Infection Leading to Nosocomial Transmission, Israel, 2017

Emerging Infectious Diseases, 2018
A patient transferred from South Africa to Israel acquired a Candida auris infection. Phylogenetic analysis showed resemblance of C. auris to isolates from South Africa but not Israel, suggesting travel-associated infection. C.
