“…the nearest taxon index; Faith's phylogenetic diversity), the NRI provided more information on the basal structure of the phylogenetic tree (i.e. deeper evolutionary dynamics; Webb, Ackerly, McPeek, & Donoghue, 2002), which makes it better suited for inferring the assembly processes on the TP as its fauna underwent a striking change during the Cenozoic period (He et al, 2020). The NRI tests the significance of the observed pattern and calculates the standardized effect size of the mean pairwise phylogenetic distance (MPD) between all species with respect to null expectations generated by randomly selecting species across the tips of the phylogeny (999 runs).

{NRI}_{sample} goodbreak= goodbreak- 1 goodbreak\times \frac{{MPD}_{sample} - {MPD}_{rnsample}}{sd ()(, {MPD}_{rnsample})}

Positive NRI values indicate phylogenetic clustering, whereas negative values indicate phylogenetic overdispersion.…”

“…55–50 million years ago) due to the Indo‐Asian Collision (Royden, Burchfiel, & van der Hilst, 2008). The subsequent mountain uplift and climatic changes have significantly influenced the historical biogeography of TP's lineages (Ding, Ree, Spicer, & Xing, 2020; Favre et al, 2015), and ultimately altered the biota on the TP over time (He, Lin, Li, Yu, & Jiang, 2020). These contexts indicate that the TP is one of the most challenging and evolutionarily unique regions on Earth (Deng, Wu, Zhou, & Su, 2019), and serves as a good model for testing the eco‐evolutionary processes that generate and maintain the diversity patterns (Favre et al, 2015; Yu et al, 2019; Ding et al, 2020).…”

Aim: Mountains harbour a rich and non-random cluster of species, yet knowledge of the species' biological attributes that support their coexistence in the montane community is limited. Here, we investigated the association of species occurrence on the Tibetan Plateau with their morphological, ecological or evolutionary constraints. Location: Tibetan Plateau (TP).Taxon: Mammals and birds. Methods:We tested whether species occurrence on the TP correlates with morphological, ecological or evolutionary constraints using the spatial distribution, phylogeny, dispersal ability and thermal niche property data for 1353 terrestrial vertebrates (383 mammals and 970 birds). We used standard (non-phylogenetic) and phylogenetic logistic regressions to elucidate the relative contributions of these attributes of species to explaining their occurrence on the TP. We assessed the geographical patterns of the community structures on the TP and fitted linear mixed models to explore the underlying eco-evolutionary forces. Results:The TP species exhibited a higher cold tolerance, wider thermal niche breadth and higher rate of niche evolution than non-TP species. We supported the assumption that the TP species were not a random subset from the species pool, but were structured jointly by environmental filtering and dispersal limitation. While dispersal and ecological processes underlying species assemblages varied spatially and among taxa, we found that species in stressful environments were limited by environmental filtering, whereas dispersal limitation was more pronounced under favourable climatic conditions.Main conclusions: Our study finds that environmental filtering and dispersal limitation jointly shape the species assemblage on the TP. These findings provide significant insights into community assembly processes on the TP and other montane ecosystems on Earth, especially those that are sensitive to global warming.

“…Grid-based analyses used the R packages raster (Hijmans, 2021) and sf (Pebesma, 2018). We excluded grid cells with fewer than 5 species to control for the negative influence of low species richness in the analysis (He et al, 2020). Ultimately, we obtained 4527 grid assemblages representing 711 species (36 species were not included due to insufficient occurrence data in our study area, Table S1.1 and Figure S2.4).…”

Aim: Biogeographic regionalization has fascinated biogeographers and ecologists for centuries and is endued with new vitality by evolutionary perspectives. However, progress is scant for most insect groups due to shortfalls in distribution and phylogenetic information, namely Wallacean and Darwinian shortfalls respectively. Here, we used the western Palearctic ants as the case to tackle these shortfalls and test their biogeographic structure through novel distribution data and phylogenetic approaches. Location: Western Palearctic realm. Taxon: Ants (Formicidae). Methods: Firstly, we developed a refined database integrating the occurrences of 747 ant species across 207 regions of the western Palearctic realm, based on newly expert-validated records derived from the existing global ant biodiversity informatics. Using range estimates for these species derived from polygons and species distribution modelling, we produced species assemblages in 50 by 50 km grid cells. We calculated taxonomic and phylogenetic turnover of ant assemblages, performing hierarchical clustering analysis using the Simpson dissimilarity index to delineate biogeographic structure. Results: At both the regional list- and grid assemblage-levels, the Mediterranean has higher turnover and more biogeographic regions than northern Europe, both taxonomically and phylogenetically. Delineations based on grid assemblages detected more detailed biogeographic transitions, while those based on regional lists showed stronger insularity in biogeographic structure. The phylogenetic regionalization suggested closer but varied affinities between assemblages in comparison to the taxonomic approach. Main conclusions: Here, we integrated expert-validated regional lists, species distribution modelling, and a recent phylogeny to tackle Wallacean and Darwinian shortfalls for an important insect group by developing a next-generation map of biogeographic regionalization for the western Palearctic ants. The results of this study suggest strong constraints from geographic barriers and potential effects of climatic history on ant distributions and evolutionary history, and also provide baseline spatial information for future investigations of regional insect distributions.

“…As such, species endemic to the TP are expected to have colonized from surrounding regions followed by vicariant speciation and diversification (Päckert et al., 2020; Wen et al., 2014). However, given that strong reconfiguration of the geographical setting and atmospheric circulation have profoundly altered the biota on the TP over the past 50 Myr (He et al., 2020; Mosbrugger et al., 2018), the origins of these species and their time of arrival on the TP remain unclear.…”

Aim The Tibetan Plateau (TP) hosts many endemic species, but questions regarding when and from where these species originated have not been comprehensively answered. Here, we provide a synthesis of the biogeographical history of terrestrial vertebrates endemic to the TP and investigate the potential drivers of their spatio‐temporal origins. Location Tibetan Plateau and its surrounding regions. Time period Cenozoic. Major taxa studied Terrestrial vertebrates. Methods We used dispersal–extinction–cladogenesis models based on time‐calibrated phylogenies to reconstruct the ancestral ranges of 174 endemic TP species and compiled the ancestral ranges and age estimates of their dispersal events. We generated a possibility map of source areas for endemic TP species by counting the incidence of non‐TP sister clades in 110 km × 110 km grid cells. We used generalized linear mixed models to assess the relative importance of historical processes and environmental factors in explaining the geographical variations in the source areas. We created subsets based on four vertebrate classes to test whether the dispersal events varied spatially and temporally among taxonomic groups. Results We found that the endemic species colonized the TP as early as 55 Ma, and that the main colonization phase started to increase around 15 Ma and peaked after 6 Ma. The major source areas of endemic TP species include the Hengduan Mountains, the Himalayas, and Central Asia. Elevation difference had the strongest effect on the source areas, followed by geographical distance. The spatio‐temporal origins of species endemic to the TP and the potential drivers showed significant differences among vertebrate classes. Main conclusions Our study supports the hypothesis that endemic TP species originated from various zoogeographical regions at different times and highlights the important roles of the TP uplift and past climatic changes for determining the spatio‐temporal origins of endemic TP species.
