Endemic but not eroded: Genomic distinctiveness and conservation genomics of the British swallowtail butterfly (Papilio machaon britannicus)

Insect Conservation and Diversity, EarlyView.
Through whole‐genome sequencing of P. machaon populations across Europe, we demonstrate that P. m. britannicus forms a genetically distinct and isolated lineage. Demographic modelling revealed weak historical gene flow from the continent. Although P. m.

Ibero‐Balearic plant disjunctions: genomic support for rapid and recurrent long‐distance colonizations of the endangered Diplotaxis ibicensis (Brassicaceae) despite no dispersal syndromes

Plant Biology, EarlyView.
Genotyping‐by‐sequencing data reveal six well‐defined clades in the endangered Diplotaxis ibicensis, endemic to the western Mediterranean Basin and indicate rapid and recurrent long‐distance colonisations across the Balearic Islands and the eastern Iberian coast despite the absence of dispersal syndromes.

Genetic Structure and Conservation Strategies for the Endangered Catfish Steindachneridion melanodermatum (Siluriformes, Pimelodidae) in the Iguaçu River, Brazil

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The endemic catfish Steindachneridion melanodermatum from the Iguaçu River basin, southern Brazil, is one of the most threatened pimelodid species. Comprehension of its genetic structure is imperative to the formulation of long‐term efficacious conservation strategies. A genetic analysis was conducted on three populations from the lower Iguaçu

RAPD Genome maps of Douglas-fir [PDF]

Journal of Heredity, 1998
We present linkage maps and estimate genome length for two hybrid individuals of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco], a coniferous tree species of wide distribution in the western United States. The hybrids were produced by crosses between the coastal (var. menziesi~) and interior (var. glauca) varieties. Haploid megagametophytes from 80

Plant Regeneration via Somatic Embryogenesis in Mature Wild Olive Genotypes Resistant to the Defoliating Pathotype of Verticillium dahliae

Frontiers in Plant Science, 2019
Regeneration capacity, via somatic embryogenesis, of four wild olive genotypes differing in their response to defoliating Verticillium dahliae (resistant genotypes StopVert, OutVert, Ac-18 and the susceptible one, Ac-15) has been evaluated.

Zebrafish as an Anti‐Isogenic Vertebrate Model and What It Reveals About Genetic Background and Reproducibility

BioEssays, Volume 48, Issue 6, June 2026.
Zebrafish illustrates how polygenic sex determination, maternal germline bottlenecks, and a structurally restless genome jointly destabilize deep homozygosity. These interlocking constraints make fully isogenic zebrafish lines effectively unattainable, turning this model into a natural “stress test” for assumptions about genetic background and ...

Genetic Relationships Among Representatives of Dasypyrum, Secale and Triticum Species Revealed with RAPD and ISSR Markers

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2014
In this study the genetic similarity among Dasypyrum, Secale andTriticum species with RAPDs and ISSRs was analyzed. To show a level of similarity between the species, 12 populations of Dasypyrum (11 D. villosum and 1 D.

Pseudotumor Cerebri Syndrome and Essential Thrombocythemia: A Case Report

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Pseudotumor cerebri syndrome (PTCS) is characterized by elevated intracranial pressure in the absence of intracranial mass lesions, structural abnormalities, or infectious conditions. Although the exact pathogenesis of PTCS remains largely elusive, it is increasingly recognized as a multifactorial condition.
