Urbanisation Leaves a Genetic Signature but No Detectable Demographic Effects in a Small Mammal Population

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Urbanisation can alter both genetic connectivity and demographic performance of wildlife populations, but these responses may occur on different temporal scales. Using multi‐year capture‐mark‐recapture data and microsatellite analyses of Eurasian red squirrels across an urbanisation gradient in Berlin, we found subtle genetic structuring without clear ...

Genomics Reveal Population Crash and Range Contraction in Elusive Fijian Hylaeus Bees

Ecology and Evolution, Volume 16, Issue 10, October 2026.
We used a novel paired low‐lying and canopy sampling technique with genomic data to assess the recently discovered canopy‐specialist Fijian Hylaeus bee clade. We found major (~99%) declines in population size since European colonisation, limited contemporary distributions and inter‐island genetic structuring.

Whole‐Genome Resequencing Reveals the Genetic Diversity and Adaptive Evolution of Rhabdophis nuchalis

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Rhabdophis nuchalis populations from four regions were analyzed using genome resequencing. The results showed that the Sichuan and Yunnan populations formed one cluster, while the Hubei and Shaanxi populations formed another. The Yunnan population displayed the highest genetic diversity.

Multiple Genetic Lineages and Inter‐Island Gene Flow in Nemadactylus monodactylus at Tristan da Cunha: Implications for Phylogeography and Taxonomy

Ecology and Evolution, Volume 16, Issue 10, October 2026.
We studied the genetics of the Five‐finger fish across the remote islands of Tristan da Cunha using mitochondrial DNA and microsatellites. mtDNA revealed four genetic clades, three of which were polyphyletic with congeners, and one potentially unique to Tristan da Cunha, suggesting current species classifications may be inaccurate.

Double mutualism: Dual rewards or redundancy? Insights from the interactions between mistletoes and their avian partners

Ecosphere, Volume 17, Issue 10, October 2026.
Abstract Mistletoes, recognized as keystone species, supply diverse floral and fruit resources for birds, thereby facilitating mutualistic interactions in pollination and seed dispersal. Some avian species are “double mutualists,” engaging in both functions. However, their precise roles and effectiveness as mutualists remain inadequately understood. In

Early Contributions Leading to Understanding the Significance of Epichloë Endophyte in Temperate Grasses

New Zealand Journal of Agricultural Research, Volume 69, Issue 5, October 2026.
The role and use of Epichloë fungal endophytes in grazed temperate grass pastures and turf grasses are now well understood with regard to balancing pasture persistence while minimising animal health and welfare concerns. However, this understanding has only emerged since the early 1980s. Prior to this, although links between Epichloë endophytes, animal

A Genomic Tool to Tackle Cryptic Diversity Demonstrates the Potential for Off‐Target Use of GT‐Seq Panels

Molecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT A comprehensive understanding of life history is vital to successful species conservation and management. When different life history stages are accompanied by considerable morphological or cryptic variation, such as the egg and larval phases exhibited by most fishes, genomic tools are essential for identifying species so that early‐life ...

A modified indirect method for computing inbreeding coefficients

Genetics Selection Evolution
The performance of existing methods for computing inbreeding coefficients—including tabular-based methods, Cholesky decomposition-based methods, and indirect methods—has been limited by either memory usage, pedigree depth, or average half-sib family size.

Importance of using genetic data to inform conservation captive breeding: A tale of two species of threatened macaws (Ara spp.)

Conservation Science and Practice, Volume 8, Issue 10, October 2026.
Unmanaged captive populations of threatened species often harbor hidden genetic risks, so using genomic tools, we audited a large private macaw collection and uncovered extensive hybridization and high inbreeding. Our findings provide an actionable framework for how routine genetic screening can be used to mitigate these risks, manage captive breeding ...

Short communication: The importance of random effects in detecting purging of inbreeding depression: A model comparison in Pannon White rabbits

Animal
Inbreeding depression (ID) is a well-documented phenomenon associated with reduced fitness and possible extinction. However, ID can be mitigated or even eliminated through the interplay of inbreeding and selection, a process known as purging.
