The global cooling beginning in the Eocene has caused coverage of tropical forests to contract from covering nearly all Africa during early Tertiary about one tenth at present time. Accompanying climate and drying was evolution traits tolerating cold drought, particularly extreme drought Sahara.

The previously released packages of the PhyloMaker series (i.e. S.PhyloMaker, V.PhyloMaker, and V.PhyloMaker2) have been broadly used to generate phylogenetic trees for ecological biogeographical studies. Although these can be any groups plants animals which megatrees are available, they focus on generating based provided by packages. How use other is not straightforward. Here, we present a new tool, called 'U.PhyloMaker', simple R script that easily large both at relatively fast speed.

Species diversity of angiosperms (flowering plants) varies greatly among regions. Geographic patterns variation in species are shaped by the interplay ecological and evolutionary processes. Here, using a comprehensive data set for regional angiosperm floras across world, we show geographic taxonomic (species) diversity, phylogenetic dispersion, deviation (i.e., after accounting diversity) world. Phylogenetic is strongly positively correlated with diversity; as result, world highly similar. Areas high located tropical regions whereas areas low temperate regions, particularly Eurasia North America, northern Africa. Similarly, dispersion is, general, higher lower However, pattern differs substantially from those dispersion. As hotspots coldspots identified based on incongruent deviations. Each these metrics may be considered when selecting to protected their biodiversity.

Abstract The tendency of species to retain ancestral ecological distributions (phylogenetic niche conservatism) is thought influence which from a pool can persist in particular environment. Thus, investigating the relationships between measures phylogenetic structure and environmental variables at global scale help understand variation richness biological assemblages across world. Here, we analyze comprehensive data set including 341,846 391 angiosperm floras worldwide explore for angiosperms regional world each individual continental (biogeographic) regions. We find that shows clear meaningful with factors. Current climatic have highest predictive power, especially on metrics reflecting recent evolutionary are also related current heterogeneity, presumably because this favors plant speciation various ways. evidence past conditions, particularly refugial play an important role determining floras. conditions differ continents, different histories their

The Qinghai-Tibet Plateau (QTP) harbours the largest wetland complex in China, with a relatively high diversity of plants. While there has been extensive research on α-diversity various plant groups QTP, study β-diversity specifically plants limited. In this study, we quantified geographic pattern from three dimensions: taxonomic, phylogenetic, and functional. We assessed relative importance distance, climatic environmental distance topographic β-diversity. results indicate consistency across dimensions. is mountainous regions at edge plateau low platform. turnover component contributes more to taxonomic than nestedness, whereas opposite true for phylogenetic functional Furthermore, higher patterns QTP are jointly influenced by filtering dispersal limitation. Climatic variables (temperature seasonality, annual precipitation, precipitation seasonality mean temperature) (elevation variation coefficient, elevation slope) were identified as main factors influencing QTP. Overall, elucidating evolutionary history formation mechanisms communities reveals large-scale diversity.

ABSTRACT Aim Tropical niche conservatism (TNC) and dispersal limitation (DL) are major ecological evolutionary mechanisms in shaping taxonomic phylogenetic β‐diversities. While these have been studied plants vertebrates, their roles freshwater taxa remain unclear. We leveraged Odonata species distribution data to map geographical patterns of β‐diversities, determine whether β‐diversity is primarily shaped by TNC or DL temperature seasonality a key driver determining TNC.

The Qinghai-Tibet Plateau (QTP) is the highest and one of most extensive plateaus in world. Investigating naturalized non-native plant species composition, phylogenetic relationships among species, between native on plateau great importance. Here, we analyze a comprehensive dataset including all vascular plants known to occur core part QTP. We use net relatedness index (NRI) nearest taxon (NTI), which reflect deep shallow evolutionary histories, respectively, quantify angiosperm species. QTP included this study (1,448,815 km2) has 9086 314 plants, respectively. find that are phylogenetically clustered with respect pool study, regardless whether NRI or NTI used. For eight regions within angiosperms positive seven their respective regional pools, reflecting clustering. Thus, subset QTP, studied as whole its constituent considered.

Invasive species may pose significant threats to biodiversity and ecosystem structure functioning. The number of introduced that have become invasive is substantial rapidly increasing. Identifying potentially preventing their expansion are critical importance in invasion ecology. Phylogenetic relatedness between native has been used predicting success. Previous studies on the phylogenetic plants at transition from naturalization shown mixed results, which be because different methods were studies. Here, I use same method analyze two comprehensive data sets South Africa China, using metrics reflecting deep shallow evolutionary histories, address question whether probability becoming higher for naturalized distantly related flora. My study suggests closely finding my consistent with Darwin's preadaptation hypothesis.
