The Importance of Effective Population Size in Conservation and Biodiversity Monitoring
Evolutionary Applications, Volume 19, Issue 1, January 2026.ABSTRACT Effective population size (Ne) is a key concept in biology and conservation. Stripped to its bare essentials, it reflects how much genetic drift a population experiences, expressed as a number of individuals of an ideal theoretical population. Superficially, Ne seems like a fairly simple concept, but the more layers of the onion you peel, the ...

Epigenetic consequences of interploidal hybridisation in synthetic and natural interspecific potato hybrids [PDF]
, 2019 Interploidal hybridisation can generate changes in plant chromosome numbers, which might exert effects additional to the expected due to genome merger per se (i.e., genetic, epigenetic and phenotypic novelties).Wild potatoes are suitable to address this ...

Genetic Allee Effects for Controlling Invasive Populations
Molecular Ecology, Volume 35, Issue 1, January 2026.ABSTRACT Invasive pests threaten food security and devastate ecosystems. A universal problem in their management is that small populations can easily evade detection. This makes identifying new incursions challenging and complicates efforts to eradicate or contain established populations.

Molecular Ecology, Volume 35, Issue 2, January 2026.ABSTRACT Parthenogenesis, or all‐female clonal reproduction, is rare among vertebrates. This is often attributed to the selective disadvantages of assumed reduction of genetic diversity in the absence of sex. However, parthenogenetic vertebrates have highly complex evolutionary histories, with most arising through hybridisation and many being polyploid.

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]
, 2014 Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

Molecular Ecology, Volume 35, Issue 2, January 2026.ABSTRACT Hybridization and introgression frequently occur even between distantly related species. A central question in speciation research is which genomic regions act as barriers to gene flow and how genome‐wide differentiation persists despite hybridization between species.

Mechanism of 2n gametes formation and centromere mapping in citrus : S02O03 [PDF]
, 2012 Citrus triploid hybrids can be recovered by 2x X 2x hybridisations as a consequence of 2n gamete formation. Two main meiotic processes are at the origin of such gametes, the first division restitution (FDR) and the second division restitution (SDR ...

Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]
, 2017 Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...
