Levels and Spatial Patterns of Effective Population Sizes in the Southern Damselfly (): On the Need to Carefully Interpret Single-Point and Temporal Estimations to Set Conservation Guidelines.

The effective population size ( ) is a key parameter in conservation and evolutionary biology, reflecting the strength of genetic drift and inbreeding. Although demographic estimations of are logistically and time-consuming, genetic methods have become more widely used due to increasing data availability. Nonetheless, accurately estimating remains challenging, with few studies comparing estimates across molecular markers types and estimators such as single-sample methods based on linkage disequilibrium or sibship analyses versus methods based on temporal variance in allele frequencies.

Development of a panel of SNP loci in the emblematic southern damselfly (Coenagrion mercuriale) using a hybrid method: pitfalls and recommendations for large-scale SNP genotyping in a non-model endangered species.

Genomic markers are essential tools for studying species of conservation concern, yet non-model species often lack a reference genome. Here we describe a methodology for identifying and genotyping thousands of SNP loci in the southern damselfly (Coenagrion mercuriale), a bioindicator of freshwater stream quality classified as near-threatened, with locally declining populations. We used a hybrid approach combining reduced representation sequencing and target enrichment.

Rapid Genetic Isolation Among Four Lineages Of Silene nutans.

Speciation is the process leading to the emergence of new species. While being usually progressive, it can sometimes be fast with rapid emergence of reproductive barriers leading to high level of reproductive isolation. Some reproductive barriers might leave signatures in the genome, through elevated level of genetic differentiation at specific loci.

The homomorphic self-incompatibility system in Oleaceae is controlled by a hemizygous genomic region expressing a gibberellin pathway gene.

In flowering plants, outcrossing is commonly ensured by self-incompatibility (SI) systems. These can be homomorphic (typically with many different allelic specificities) or can accompany flower heteromorphism (mostly with just two specificities and corresponding floral types). The SI system of the Oleaceae family is unusual, with the long-term maintenance of only two specificities but often without flower morphology differences.

Genetic diversity assessment of (Asteraceae) for the genetic restoration of declining populations.

(L.) Moench (Asteraceae) is a self-compatible, insect-pollinated herb occurring in sand grasslands, and is declining and endangered in many parts of its European distribution range. A recovery plan of has been conducted in southern Belgium, involving plant translocations.
