ABSTRACT Aim The riverine barrier hypothesis is often tested as a driver for allopatric speciation. Rivers are usually treated static landscape features characterised by their width and elevation of headwaters. We aim to investigate the role rivers barriers using comprehensive database geomorphological characteristics assessing influence on species turnover rates. Location Eastern Madagascar. Taxon Sixty‐two taxa from 11 genera lemurs, amphibians reptiles. Methods compiled 21 variables 45 major rivers, estimated rates assemblages either side modelled river diversity. Topographic depressions, identified longitudinal profiles, heterogeneity were further analysed potential palaeoclimatic refugia alternative speciation drivers. Results A total 24 acted barriers. Three these had disproportionately high shared set distinct like maximum watershed, flow accumulation values at outlet an 800 m concavity profile. Other along main channel length coastal plain helped differentiate between with intermediate Species richness peaked in northeastern Madagascar, region highest abundance topographic depressions inferred palaeo‐wetlands. Main Conclusions Geomorphological effectively explained variations However, it remains uncertain whether functioned secondary dispersal thereby maintainers diversity, rather than primary drivers Additionally, we emphasise during oscillations, which associated depressions. Overall, integrating dynamic fluvial systems through space time into biogeographic studies offers valuable insights speciation, persistence taxa.

Uncarina contains 14 species of woody plants endemic to Madagascar. Its occurrence across dryland biomes on the island make it an interesting system study diversification flora. Using samples all and 512 nuclear loci, we reconstructed phylogenetic trees examine relationships assess their monophyly. We also studied historical biogeography genus combined leaf trait data derived from SEM photography trichomes geometric morphometric analysis shape better understand its biomes. is monophyletic, major clades showed a clear biogeographical signal. Leaf traits corroborated among clades. Although most are at least one cryptic exists. Uncarina, like many arid-adapted plant lineages in Madagascar originated Miocene or Pleistocene. Geographic movement has been primarily along south-north axis, with river basins apparently acting as barriers gene flow. The evolution spiny thicket dry forest biome.

Abstract Lorantheae is the largest tribe within Loranthaceae family. However, relationships among genera of African have been poorly understood due to limited molecular data and taxon sampling in previous studies. Understanding phylogenetic developing a stable classification requires robust phylogeny. To address this, we obtained complete plastomes, nuclear ribosomal DNA 18S‐ITS1‐5.8S‐ITS2‐26S, mitochondrial sequences for 61 accessions using genome skimming attempt resolving recalcitrant this lineage. The included representatives all from subtribal classification. Analysis plastome dataset resulted well‐supported phylogeny with four clades. topologies based on datasets were generally congruent, only minor discordance at position some genera. Topology was, however, not congruent those other datasets, few incongruent nodes detected. Our phylogenomic analyses largely resolve Lorantheae, supporting monophyly its subtribes most genera, except Agelanthus Oncocalyx . Based well‐resolved phylogenies, propose two new provide circumscriptions subtribes.
