“…() was caused by using an invalid likelihood function. Considering the ongoing debate, we ran a number of separate B amm analyses, an approach that was also recently used in Campanula (Jones et al ., ). We initially conducted an analysis with the prior set as 1 for the ‘ExpectedNumberofShifts’ as suggested for small trees (< 500 tips).…”

Insights into the historical assembly of East Asian subtropical evergreen broadleaved forests revealed by the temporal history of the tea family

Subtropical evergreen broadleaved forests (EBLFs) inhabit large areas of East Asia. Although paleovegetation reconstructions have revealed that the subtropical EBLFs existed in Southwest China during the Miocene, the historical construction of these forests remains poorly known. Here, we used the tea family (Theaceae), a characteristic component of the subtropical EBLFs, to gain new insights into the assembly of this important biome. Using a robust phylogenetic framework of Theaceae based on plastome and nuclear ribosomal DNA sequence data, the temporal history of the family was reconstructed. Data from other characteristic components of subtropical EBLFs, including Fagaceae, Lauraceae and Magnoliaceae, were also integrated. Most of the essential elements of the subtropical EBLFs appear to have originated around the Oligocene-Miocene (O-M) boundary. However, small woody lineages (e.g. Camellia, Hartia) from Theaceae were dated to the late Miocene. Accelerated net diversification rates within Theaceae were also detected near the O-M transition period and the late Miocene. Our results suggest that two independent intensifications of the East Asian summer monsoon (EASM) around the O-M boundary and the late Miocene may have facilitated the historical assembly of the subtropical EBLFs in East Asia.

“…However, Rabosky et al [ 48 ] demonstrated that the conclusion of Moore et al [ 47 ] resulted from an invalid likelihood function, and suggest that in the most recent version of BAMM (v.2.5), the extreme sensitivity to the prior cannot be replicated. Considering this ongoing debate, we performed multiple BAMM analyses, similar to previous studies of Campanula [ 49 ] and Theaceae [ 11 ], by using various prior values (0.5, 1, 2, 5, and 10) to determine whether our results were affected by different prior settings.…”

Insights into the historical assembly of global dryland floras: the diversification of Zygophyllaceae

BackgroundDrylands cover nearly 41% of Earth’s land surface and face a high risk of degradation worldwide. However, the actual timeframe during which dryland floras rose on a global scale remains unknown. Zygophyllaceae, an important characteristic component of dryland floras worldwide, offers an ideal model group to investigate the diversification of dryland floras. Here, we used an integration of the phylogenetic, molecular dating, biogeographic, and diversification methods to investigate the timing and patterns of lineage accumulation for Zygophyllaceae overall and regionally. We then incorporated the data from other dominant components of dryland floras in different continents to investigate the historical construction of dryland floras on a global scale.ResultsWe provide the most comprehensive phylogenetic tree for Zygophyllaceae so far based on four plastid and nuclear markers. Detailed analyses indicate that Zygophyllaceae colonized Africa, Asia, Australia, and the New World at different periods, sometimes multiple times, but Zygophyllaceae lineages in the four regions all experienced a rapid accumulation beginning at the mid-late Miocene (~ 15–10 Ma). Other eleven essential elements of dryland floras become differentiated at the same time.ConclusionsOur results suggest that the rise of global dryland floras is near-synchronous and began at the mid-late Miocene, possibly resulting from the mid-Miocene global cooling and regional orogenetic and climate changes. The mid-late Miocene is an essential period for the assembly and evolution of global dryland floras.Electronic supplementary materialThe online version of this article (10.1186/s12862-018-1277-z) contains supplementary material, which is available to authorized users.

“…To date, little was known concerning the evolutionary relationships within this group. Although past studies (e.g., Mansion & al., 2012;Jones & al., 2017) provided preliminary evidence of the polyphyly of C. sect. Quinqueloculares, our results offer the first comprehensive phylogenetic framework that includes a complete taxon sampling and 10 molecular markers.…”

Campanula sect. Quinqueloculares (Campanulaceae), consisting of ca. 39 mostly chasmophytic species, is one of the most morphologically variable groups in Campanula and includes numerous endemics occurring mostly in Greece and/or Turkey. In this molecular study, we aim to test the monophyly of C. sect. Quinqueloculares and provide divergence time estimates to generate hypotheses into the historical processes responsible for the diversification and current distribution patterns of this group. Individual and combined data matrices consisting of plastid (NADHS-2, rpoC1-1, rpoC2-1, rpoC2-2, rpoC2-3, trnT-trnL) and nuclear (2017561, ITS, PPR11, PPR70) markers were constructed for 121 taxa. Results indicate that C. sect. Quinqueloculares, as traditionally circumscribed, is polyphyletic. Species are largely clustered into two well-supported clades, except for three taxa excluded from these groups. Additionally, a few taxa belonging to other sections are confidently nested within the two Quinqueloculares clades. The first clade (Greek clade) includes one isophylloid species nested with 25 Greek endemics belonging to C. sect. Quinqueloculares. The second clade (Southeastern Aegean-Turkish clade) comprises 20 C. sect. Quinqueloculares taxa and 3 species of C. sect. Rupestres, all distributed in the southeastern Aegean and Turkey. Divergence time estimates suggest that these clades originated in the Late Miocene. Temporal and geographic patterns are consistent with a vicariant scenario driven by geological events during the Miocene, such as the formation of the Mid-Aegean trench and the Messinian salinity crisis.
