Additive Variance and Open‐Pollinated Progenies Under Mixed Mating

Plant Breeding, EarlyView.
ABSTRACT Open‐pollinated progeny tests are still widely interpreted as if all the individuals within a maternal family were true half‐sibs. However, in species with mixed mating systems, this assumption is often biologically unrealistic and may bias the estimation of the additive variance, narrow‐sense heritability and expected selection gains.

Assessment of inbreeding coefficients and inbreeding depression on complex traits from genomic and pedigree data in Nelore cattle

BMC Genomics
Nelore cattle play a key role in tropical production systems due to their resilience to harsh conditions, such as heat stress and seasonally poor nutrition. Monitoring their genetic diversity is essential to manage the negative impacts of inbreeding.

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Integrative Taxonomy of Pachygrontha (Heteroptera: Pachygronthidae) in East and Southeast Asia Reveals New Insights Into Species and Group Delimitation

Ecology and Evolution, Volume 16, Issue 7, July 2026.
This manuscript presents a comprehensive taxonomic revision of the insect genus Pachygrontha in East and Southeast Asia, addressing the critical need for robust species delimitation in closely related lineages. Our research employs an integrative approach, combining detailed morphological examination with complete mitochondrial genomes and genome‐wide ...

First Insight Into Multiple Paternity in the Potato Cyst Nematode Globodera pallida Facing Masculinizing Plant Resistance

Ecology and Evolution, Volume 16, Issue 7, July 2026.
This study demonstrated multiple paternity in the potato cyst nematode Globodera pallida: all females were polyandrous. Moreover, the female mating rate with different males appeared to remain stable, i.e., an average of seven fathering males, throughout the adaptation process to a masculinizing potato resistance.

Multi‐Marker Mitochondrial Analysis Reveals Genetic Diversity and Phylogenetic Relationships of Black Sea Sturgeons (Acipenseridae)

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Sturgeons are an important species due to their complex genetic structure and evolutionary characteristics. Unfortunately, they are threatened with extinction due to illegal and overfishing, as well as the loss of their natural habitats. In our work, we examine the genetic diversity of four sturgeon species that inhabit the Black Sea basin and its ...

Weak Structure and Environment‐Associated Loci Across a Eutrophication Gradient in a Resilient Coral Species

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Marine species often have large effective population sizes and high connectivity that reduce drift and preserve diversity, but how these features shape adaptation to anthropogenic change remains unclear; Oulastrea crispata, a stress‐tolerant Indo‐Pacific coral, is an ideal test case along a strong eutrophication gradient. Using RADseq on 90 individuals

Long runs of homozygosity are reliable genomic markers of inbreeding depression

Trends in Ecology & Evolution
A long-standing goal in ecological, evolutionary, and conservation genetics is to identify genomic correlates of fitness and inbreeding depression. Over the past several years, a growing body of theoretical and empirical work in diverse mammal and bird taxa has established a strong link between long runs of homozygosity (ROH) and inbreeding depression.

Inbreeding patterns and genetic diversity under selection in Teha sheep

Frontiers in Genetics
BackgroundInbreeding and genetic diversity are critical factors influencing the adaptability, productivity, and sustainability of livestock populations. Teha sheep, a crossbred line between Texel and Kazakh sheep, are an important meat-producing breed in
