Abstract Aim Evolutionary studies of oceanic island endemics are usually focused on lineages that have experienced in situ radiation, while those speciated once the or archipelago but not further diversified (single‐species endemics) remain understudied. The Macaronesian archipelagos, Atlantic Ocean, home to significant numbers single‐species endemics. genus Hedera L. (12 species) includes three from archipelagos with putatively independent origins. Here, we tested role phylogenetic niche conservatism their evolution. To end, (1) reconstructed spatio‐temporal origin ivies using phylogenomics, and (2) assessed climatic during colonization speciation. Location Azores, Canary Islands, Madeira, western Mediterranean. Taxon spp. Methods We used 166 samples representing all species generate genotyping‐by‐sequencing (GBS) libraries performed time‐calibrated phylogenomic biogeographic analyses. Climatic preferences evolution were a geo‐referenced database ivy (2,297 records). Results Independent asynchronous speciation estimated for ivies, resulting different degrees differentiation: H. canariensis displayed an early divergence (7.5–12 Ma) high isolation; azorica had intermediate isolation its closest relative helix (4.4–6.8 maderensis was embedded within climatically similar iberica (2.8–4.6 . A strong signal suggested clade , where placed. Main Conclusions represent evolutionary stages leading emergence appears be involved endemics, first by facilitating colonization, then limiting diversification.

Abstract The spatial distribution of individuals within ecological assemblages and their associated traits behaviors are key determinants ecosystem structure function. Consequently, determining the species, how distributions influence patterns species richness across ecosystems today in past, helps us understand what factors act as fundamental controls on biodiversity. Here, we explore niche modeling has contributed to understanding spatiotemporal past biodiversity evolutionary processes. We first perform a semiquantitative literature review capture studies that applied models (ENMs) identifying 668 studies. coded each study according focal taxonomic group, whether used fossil evidence, it relied evidence or methods addition ENMs, scale study, temporal intervals included ENMs. trends publication categories anchor discussion recent technical advances modeling, focusing paleobiogeographic ENM applications. then explored contributions ENMs paleobiogeography, with particular focus examining drivers range dynamics; phylogeography within-lineage macroevolutionary processes, including change, speciation, extinction; community assembly; conservation paleobiogeography. Overall, powerful tools for elucidating patterns. most commonly Quaternary dynamics, but an increasing number use gain important insight into both processes pre-Quaternary times. Deeper integration phylogenies may further extend those insights.

Globally, endemic species and natural habitats have been significantly impacted by climate change, further considerable impacts are predicted. Therefore, understanding how change can aid in advancing the necessary conservation initiatives.

Reaumuria trigyna is endemic species in Eastern Alxa West Ordos desert regions China. The has been considered a good candidate explore unique strategies plants that inhabit this area. In study, we performed genomic analyses based on restriction‐site associated DNA sequencing understand genetic diversity, structure, differentiation species. Analyses 92,719 high‐quality single‐nucleotide polymorphisms (SNPs) indicated overall R. was low ( H O = 0.249 E 0.208). No significant observed among investigated populations. However, subtle structure detected. We suggest might be explained by diversification reinforced geographical isolation Overall, 3513 outlier SNPs were located 243 gene‐coding sequences transcriptome.
