Article Abstract
Climatic upheavals throughout Earth's history have driven species to subterranean refugia, where stable microclimates buffer environmental extremes. The spider family Pimoidae, relict lineages sensitive to thermal fluctuations, exemplifies this climate-driven habitat transition. Here, we present the first chromosome-level genome of Pimoa clavata, a troglophilic spider endemic to Beijing's mountainous caves. Combining PacBio HiFi and Hi-C sequencing, we assembled a 1.94 Gb genome with 29 scaffolds in chromosomes level, which were further subjected to comprehensive annotation. The well-annotated genome of this species provides foundational insights into the genomic basis of subterranean adaptation, offering critical resources for evolutionary genomics and conservation of climate-vulnerable cave species.

Heterostyly is a polymorphic floral adaptation controlled by supergenes. The molecular basis of distyly has been investigated in diploid species from several unrelated families, but information is lacking for polyploid systems. Here, we address this knowledge gap in Schizomussaenda henryi, a tetraploid distylous species of Rubiaceae, the family with the greatest number of heterostylous species.

, as one of the common blowflies, displays biological characteristics, such as ovoviviparity and carrion-feeding adaptation. Thus, this species is generally considered of significant ecological, medical, and forensic importance. However, without a high-quality pseudo-chromosome genome for , elucidating its evolutionary trajectory proved difficult.

Quaternary climatic fluctuations had a substantial influence on ecosystems, species distribution, phenology and genetic diversity, driving extinction, adaptation and demographic shifts during glacial periods and postglacial expansions. Integration of genomic data and environmental niche modelling can provide valuable insights on how organisms responded to past environmental variations and contribute to assessing vulnerability and resilience to ongoing climatic challenges. Among vertebrates, turtles are particularly vulnerable to habitat changes because of distinctive life history traits and the effect of environmental conditions on physiology and survival.

How evolution builds genes, how these genes attain enhanced expression, and how they integrate into existing regulatory networks to drive phenotypic diversification are all fascinating questions. Here, we generated chromosome-level genome assemblies for two Rosa banksiae subspecies and re-sequenced an additional 40 rose accessions. Genomic analysis of more than 100 Rosa accessions revealed multiple evolutionary steps leading to the de novo origination of a taxon-restricted gene, SCREP, specific to the rose lineage.

Mangrove plants, originating from inland ancestors, have independently adapted to extreme intertidal zones characterized by salt and hypoxia stress. While typical mangroves exhibit specialized phenotypes, like viviparous seeds and salt secretion, atypical clades that have thrived without such traits are particularly suitable for exploring the molecular and physiological basis underlying plant adaptation to intertidal zones. We assembled a chromosome-level genome of an atypical mangrove, Scyphiphora hydrophylacea, the only mangrove species in Gentianales.
