Text-fig. 6. Stratigraphic and phylogenetic placement inferred for fossil Fraxinus fruits. Only Fraxinus fossil fruits identified on the section level are included. The black color represents selected fossil fruits from published literature (excluding some Eocene North American occurrences not assigned to section), the red color represents the fossil fruits from the Lühe flora, Yunnan, Southwest China. The phylogenetic relationships are based on Hinsinger et al. (2013). in Fraxinus L. (Oleaceae) Fruits From The Early Oligocene Of Southwest China And Their Biogeographic Implications

Contrasting patterns of phylogenetic diversity and alpine specialization across the alpine flora of the American mountain range system
<p>Although mountainous habitats contribute substantially to global biodiversity, comparatively little is known about biogeographic patterns of distributions of alpine species across multiple mountain ranges. Here, we present a detailed analysis of the distributions and phylogenetic affinities of alpine seed plant lineages across North, Central, and South American mountain systems. Using a comprehensive dataset that characterized the elevational niches of American seed plants in a continuously valued way, we were able to quantitatively investigate how the proportion of alpine habitat occupied by plants related to their biogeographic distributions at a regional scale and place these results in a phylogenetic context. We found alpine species diversity to be greatest in the central Andes and western North America, and that sites with lower phylogenetic diversity contained species with a greater degree of alpine specialization. In particular, near Arctic/ boreal alpine communities were characterized by low phylogenetic diversity and higher degrees of alpine specialization, whereas the opposite was observed for southern Patagonian communities. These results suggest that abiotic filtering alone in these climatically similar regions is unlikely to explain alpine community assembly. Nevertheless, the overall relative rarity of alpine specialists, and the tendency for such specialists to be most closely related to montane lineages, suggested that filtering was still an important factor in shaping alpine community structure. This work corroborates the importance of a nuanced and scale-dependent perspective on the 'history-filtering' debate axis, as both factors have likely contributed to modern biodiversity patterns observed in alpine plant communities across the Americas.</p>

Spatial phylogenetics of the North American moss flora
<p><strong>Aim: </strong>We documented patterns of phylogenetic diversity (PD) and phylogenetic endemism (PE) in the moss flora of North America, determined how environmental variables explain these patterns, compared patterns in mosses to known patterns in angiosperms, and explored how patterns driven by subclades might conflict with patterns driven by other subclades.</p> <p><strong>Location:</strong> North America north of Mexico</p> <p><strong>Taxon:</strong> Mosses (Bryophyta)</p> <p><strong>Methods:</strong> A maximum-likelihood tree inferred from publicly available sequence data, and locality data from ca. 7.5 × 10<sup>5</sup> herbarium specimens, were combined to build a dataset of 935 species (representing ca. 67% of the known moss flora). Spatial randomization procedures were used to find significance levels of PD and relative phylogenetic diversity (RPD) for the full dataset and three major subclades, as well as to carry out a Categorical Analysis of Neo- and Paleo-Endemism (CANAPE). Range weighted turnover in both species and PE was used to identify phytogeographic regions across the continent. Ordinations of environmental data were used to determine the distribution of PD, RPD, and phytogeographic regions within environmental space. Results of this study were compared to known patterns of phylodiversity in angiosperms.</p> <p><strong>Results: </strong>Phylodiversity is distributed non-randomly. Some patterns, for example long branches in the southeastern US, are consistent with angiosperms, however there are strong contrasts as well. Overall patterns of PD and RPD are strongly influenced by different phylogenetic scales within mosses, indicating that signal from one clade can obscure patterns in others. Three primary phytogeographic zones are defined by both differing geological histories and differing current abiotic conditions Phytogeographic regions, PD, and RPD are all aligned with environmental variables.</p> <p><strong>Main conclusions: </strong>There is evidence for both ecological and historical factors in shaping the moss flora of North America, and biogeographic differences between angiosperms and mosses appear to align with important life-history differences between the two groups.</p>
