License to Replicate: Mechanisms of Licensing Eukaryotic Origins for DNA Replication
BioEssays, Volume 48, Issue 1, January 2026.Origin licensing constitutes the first step in initiating eukaryotic genome replication. Licensed origins are marked by an MCM double hexamer complex. This article reviews the molecular mechanisms of MCM double hexamer loading in yeast and higher eukaryotes, based on insights gained from biochemical reconstitution and structural analyses.

Zipping up the Synaptonemal Complex: Pathways to Homologous Chromosome Synapsis
BioEssays, Volume 48, Issue 1, January 2026.The synaptonemal complex (SC) is a conserved protein structure that assembles between homologous chromosomes during meiosis. Here, we review pathways promoting homologous synapsis across model organisms, examining coordination with homolog pairing and recombination, spatiotemporal regulation of SC assembly, and the conserved molecular modules coupling ...

Operational sex ratio bias due to sex‐specific cohort splitting in response to predation
Ecosphere, Volume 17, Issue 1, January 2026.Abstract The operational sex ratio (OSR), that is, the local ratio of fertilizable females to sexually active males at any given time, is of key importance for the strength of sexual selection and the reproduction of populations. We hypothesize that sex‐specific cohort splitting, that is, when one sex mostly metamorphoses while the other mostly enters ...

Conservation challenges and opportunities for native apple (Malus) species in Canada
PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 134-156, January 2026.Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.

Preliminary genetic barcodes for ash (Fraxinus) species and generation of new wide hybrids
PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 245-258, January 2026.Societal Impact Statement The world‐wide diversity of ash trees includes genetic information encoding resistance to the ash dieback fungus and the emerald ash borer beetle, which are currently devastating ash populations in Europe and North America. In order to mobilise this genetic diversity in conventional breeding programmes, we need to be able to ...

Accumulating time lags across biodiversity levels following land‐use change
Journal of Ecology, Volume 114, Issue 1, January 2026.Species identity seems central in governing the observed delays at each level of biodiversity, from genetic to functional diversity. In particular, species identity controls the slowest responses at the genetic level, potentially leading to accumulating underestimations of the size and duration of time lags at species, community and functional ...

Short‐Read Pangenomes and Their Potential Utility in Population and Conservation Genomics
Molecular Ecology Resources, Volume 26, Issue 1, January 2026.ABSTRACT As a collection of all the genetic variants in the gene pool, the pangenome is a concept that will become fundamental to conservation genomic studies. Unfortunately, most pangenomic approaches developed for humans and model organisms are financially impractical for conservation genomic studies of threatened or endangered species due to the ...
