Data for: From southern Africa and beyond: historical biogeography of a monocotyledonous bulbous geophyte
<p><em><strong>Aim</strong></em></p> <p>Low taxon sampling and taxonomic uncertainties still obscure our evolutionary knowledge of many taxa, especially widespread lineages across diverse landscapes. Of particular interest are those lineages inhabiting seasonal and arid landscapes, which showcase unique distributional patterns that hint at fascinating histories. Using the most comprehensive sampling to date of a widespread bulbous monocot, we hypothesize two independent dispersals to Madagascar, and that vicariance due to Miocene-driven aridification contracted a once-widespread distribution between Africa and Eurasia.</p> <p><em><strong><span>Location</span></strong></em></p> <p><span>Sub-Saharan Africa, Madagascar, Eurasia</span></p> <p><em><strong>Taxon</strong></em></p> <p>Ledebouriinae (Scilloideae, Asparagaceae)</p> <p><em><strong>Methods</strong></em></p> <p>Using the Angiosperms353 probe set for 195 taxa (86 ingroup taxa), we perform phylogenetic reconstruction using IQ-Tree, and we infer age estimates using penalized likelihood as implemented in treePL. Capitalizing on our broad geographic sampling, which includes African, Malagasy, and Eurasian taxa, we use 'BioGeoBEARS' to reconstruct ancestral ranges and investigate the role of vicariance and dispersal. </p> <p><em><strong>Results</strong></em></p> <p>The Ledebouriinae originated within the past ~30 myr in southeastern sub-Saharan Africa, with the major subclades arising soon thereafter. Although long-distance dispersal cannot be fully ruled out, we argue that vicariance was the major process responsible for the current distribution of <em>Ledebouria</em> in Eurasia. We recover two distinct <em>Ledebouria</em> groups that overlap in eastern Africa, but are divided into mostly northern and southern clades with divergent biogeographical histories, each showing an independent dispersal to Madagascar. A similar north-south split is seen in <em>Drimiopsis</em>. Additionally, we recover a complex biogeographic history in the predominantly sub-Saharan African Ledebouria clade, with a rapid radiation at ~14 mya.</p> <p><em><strong>Main conclusions</strong></em></p> <p>The expansion of seasonal rainfall and aridity in sub-Saharan Africa, coupled with orogenic activity, may have fostered the diversification of the Ledebouriinae and many subclades. Miocene-driven aridification may have caused fragmentation of a once widespread distribution that led to their occurrence in Eurasia.</p>
Data from: Historical biogeography supports Point Conception as the site of turnover between temperate East Pacific ichthyofaunas
<p>The cold temperate and subtropical marine faunas of the Northeastern Pacific meet within California as part of one of the few eastern boundary upwelling ecosystems in the world. Traditionally, it is believed that Point Conception is the precise site of turnover between these two faunas due to sharp changes in oceanographic conditions. However, evidence from intraspecific phylogeography and species range terminals do not support this view, finding stronger biogeographic breaks elsewhere along the coast. Here I develop a new application of historical biogeographic approaches to uncover sites of transition between faunas without needing an <em>a priori</em> hypothesis of where these occur. I used this approach to determine whether the point of transition between northern and southern temperate faunas occurs at Point Conception or elsewhere within California. I also examined expert-vetted latitudinal range data of California fish species from the 1970s and the 2020s to assess how biogeography could change with the backdrop of climate change. The site of turnover was found to occur near Point Conception, in concordance with the traditional view. I suggest that recent species- and population-level processes could be expected to give signals of different events from historical biogeography, possibly explaining the discrepancy across studies. Species richness of California has increased since the 1970s, mostly due to species's ranges expanding northward from Baja California (Mexico). Range shifts under warming conditions seem to be increasing the disparity between northern and southern faunas of California, creating a more divergent biogeography.</p>

Fig. 22 in Revision, phylogeny and historical biogeography of the genus Apodrosus Marshall, 1922 (Coleoptera: Curculionidae: Entiminae)
Fig. 22. Distilled version of the DIVA analysis (see Fig. 21; taxa replaced with their respective areas), with unambiguously optimized ancestral areas and inferred events of vicariance (//) and colonization (=>). Area labels as in Fig. 21. See text for further detail.
Fig. 20 in Revision, phylogeny and historical biogeography of the genus Apodrosus Marshall, 1922 (Coleoptera: Curculionidae: Entiminae)
Fig. 20. Phylogeny of the species of Apodrosus and select outgroup taxa according to the single most parsimonious cladogram (L=61; CI=42; CI=74). Character 15 is mapped under DELTRAN optimization, whereas character 25 is mapped under ACCTRAN optimization (cf., Agnarsson & Miller 2008); all other characters have unambiguous optimizations. Black rectangles represent single, non-homoplasious character state transformations and white rectangles represent multiple, homoplasious character state transformations. The small numbers above and below each rectangle correspond to character numbers and states, respectively. The larger numbers displayed at the left end of each branch represent Bremer support values.
