Discovering the unseen: A performance comparison of taxonomic classification methods for unknown DNA barcodes

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 9, Page 2574-2593, September 2026.
Abstract DNA barcoding and metabarcoding have emerged as cost‐efficient, standardized methods for characterizing local biodiversity. Based on the sequencing of a small targeted gene fragment, it is theoretically possible to identify a wide diversity of taxa by comparing them with reference sequence databases.

Isolation and characterization of three interspersed repeated DNA sequences in the western whip snake (Hierophis viridiflavus)

open access: yes, 2013
To date the knowledge of repeated elements in the snake genome is scarce and mostly limited to various satellite and microsatellite sequences, found in species belonging to different taxonomic groups.

SIRT1 Silences L1 Retrotransposons by Stabilizing Heterochromatin‐Modifying Complexes

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
SIRT1 binds the LINE‐1 5′‐UTR and recruits the heterochromatin modifiers Lamin B1 and KAP1 to maintain H3K9me3 levels, thereby suppressing LINE‐1 retrotransposition. SIRT1 deficiency enhances LINE‐1 transcription, leading to upregulation of senescence‐associated secretory phenotype factors, activation of the cGAS‐STING pathway, and consequent cellular ...

Environmental DNA Reveals Distinct Regions of Extraordinary Marine Biodiversity to Inform a Newly Established Marine Park—Exmouth Gulf, Western Australia

open access: yesDiversity and Distributions, Volume 32, Issue 9, September 2026.
ABSTRACT Aim Exmouth Gulf, Western Australia, is a globally significant refuge for many marine megafauna species. The recent designation of a marine park in Exmouth Gulf underscores its environmental, social and cultural significance but remains a site of competing interests.

Multispecies Genomics Uncovers a Common Legacy of Postglacial Isolation on a Neotropical Land‐Bridge Island

open access: yesJournal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim To evaluate whether Pleistocene sea‐level changes can explain the timing and demographic processes of population divergence between continental and insular plant populations on a land‐bridge island. Location Alcatrazes Island and adjacent mainland areas along the southeastern coast of Brazil.

Museum Genomics of an Important Swedish Pollinator Reveals Population Stability Across Time

open access: yesMolecular Ecology, Volume 35, Issue 18, September 2026.
ABSTRACT Anthropogenic activity has driven a rapid decline in wild pollinator populations over the last several decades. Understanding the genomic consequences of these declines and their long‐term effects requires establishing historical baselines for population diversity. To investigate this, we conducted temporal genomic analyses of a widespread and

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2799-2817, September 2026.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Persistent Epigenetic Reprogramming Is Associated With Contrasting Drought‐Response Strategies in Citrus Scion–Rootstock Systems

open access: yesPhysiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Recurrent drought limits the productivity of perennial crops such as citrus, whose tolerance to water deficit largely depends on scion–rootstock interactions. Although physiological responses to recurrent drought are well documented, the epigenetic states associated with these responses remain poorly understood, limiting the use of epigenetic ...
