Hybridization has significant evolutionary consequences across the Tree of Life. The process hybridization played a major role in plant evolution and contributed to species richness trait variation. Since morphological traits are partially product their environment, there may be link between ecology. Plant hybrid is noted higher harsh environments, we explore this hypothesis with keystone tropical lineage, palms (Arecaceae). Leveraging recent literature review naturally occurring palm hybrids, developed method calculate frequency, then tested if phylogenetic signal hybrids using phylogeny all palms. Further, used comparative methods examine interaction frequency presence dry on islands, genera. Phylogenetic generalized least squares models had stronger support than random association, indicating for island environments. However,

Abstract Fluctuations in genomic repetitive fractions (repeatome) are known to impact several facets of evolution, such as ecological adaptation and speciation processes. Therefore, investigating the divergence elements can provide insights into an important evolutionary force. However, it is not clear how different element clades impacted by factors changes and/or phylogeny. To discuss this, we used Neotropical legume genus Erythrostemon (Caesalpinioideae) a model, given its ancient origin (~33 Mya), lineage‐specific niche conservatism, macroecological heterogeneity, disjunct distribution Meso‐ South American (MA SA respectively) lineages. We performed comparative repeatomic analysis 18 species test environmental variables over repeats diversification. Overall, repeatome composition was diverse, with high abundances satDNAs Ty3/gypsy‐Tekay transposable elements, predominantly MA lineages respectively. unexpected profiles unrelated phylogeny/biogeography were found few ( E. coccineus , pannosus placidus ) calycinus species, related reticulate evolution incongruence between nuclear plastid topology, suggesting hybridizations. The plesiomorphic Tekay satDNA pattern altered MA‐sensu stricto subclade striking differentiation (expansion retraction Tekay) associated colonization new environment Central America around 20 Mya. Our data reveal that current species‐specific pool result two bursts amplification probably Miocene, distinct patterns for repeatomes. This suggests strong role modulators genome–environment interaction providing macroevolutionary about mechanisms plant diversification across space time.

Summary Increasing genome size (GS) has been associated with slower rates of DNA replication and greater cellular nitrogen (N) phosphorus demands. Despite most plant species having small genomes, the existence larger GS suggests that such costs may be negligible or represent benefits under certain conditions. Focussing on widespread diverse grass family (Poaceae), we used data species' climatic niches growth different environmental conditions to test for GS. The influence photosynthetic pathway, life history evolutionary was also explored. We found history, pathway all distribution Genomes were smaller in annual C 4 species, latter allowing cells necessary leaf anatomy. high N availability and, perennial low growth‐season temperature. Our findings reveal is a globally important predictor performance dependent are likely due cell sizes, rapid biomass production where soil fertility meets demands and/or when occurs via temperature‐independent expansion.
