“…This pattern was reported earlier by Taylor et al (2021), using inventories and distribution information for 27,850 epiphyte species derived from literature sources, where Orchidaceae comprises 67% of the epiphytic flora, Bromeliaceae (11%) and Araceae (4%) being the dominant plant families. Marcusso et al (2022) it also reported this same pattern for the Neotropics and our results confirm this for Amazonia. Noteworthy, most of Araceae species (60%) recorded in our inventories are excluded in the new classification of vascular epiphytes and are now considered vines by Zotz (2013) and Zotz et al (2021).…”

“…Amazonia VEA characterized from inventories of a similar region, even when sampled from different environments, are more floristically similar when compared among regions. A similar pattern was reported by Marcusso et al (2022) where some distant areas in Amazonia Basin were grouped in the same cluster. Such as pattern would suggest a "spillovereffect" where habitat types in proximity literally "share" species through constant propagule rain.…”

Epiphytes are still an understudied plant group in Amazonia. The aim of this study was to identify distributional patterns and conservation priorities for vascular epiphyte assemblages (VEA) across Amazonia. We compiled the largest Amazonian epiphyte plot database to date, through a multinational collaborative effort of 22 researchers and 32 field sites located across four Amazonian countries – the Amazonian Epiphyte Network (AEN). We addressed the following continental-scale questions by utilizing the AEN database comprising 96,448 epiphyte individuals, belonging to 518 vascular taxa, and growing on 10,907 tree individuals (phorophytes). Our objectives here are, first, to present a qualitative evaluation of the geographic distribution of the study sites and highlight regional lacunae as priorities for future quantitative inventories. Second, to present the floristic patterns for Amazonia-wide VEA and third, to combine multivariate analyses and rank abundance curves, controlled by major Amazonian habitat types, to determine how VEA vary geographically and ecologically based on major Amazonian habitat types. Three of the most striking patterns found are that: (1) VEA are spatially structured as floristic similarity decays with geographic distance; (2) a core group of 22 oligarchic taxa account for more than a half of all individuals; and (3) extensive floristic sampling gaps still exist, mainly across the highly threatened southern Amazonian deforestation belt. This work represents a first step toward unveiling distributional pattern of Amazonian VEA, which is important to guide future questions on ecology and species distribution ranges of VEA once the collaborative database grows allowing a clearer view of patterns.

“…Epiphytes are most diverse in tropical regions, especially in the Neotropics ( Zotz, 2005 ; Suissa, Sundue & Testo, 2021 ) and there are extreme cases of high abundance where they can cover most of the surface area of the host tree. Hundreds of papers have been published since the late 1800s describing the ecology, biogeography, taxonomy, and population genetic structure of epiphytes ( Zotz & Hietz, 2001 ; Zotz, 2013a ; Menini Neto et al, 2016 ; Zotz, Hietz & Einzmann, 2021c ; Chaves et al, 2021 ; Taylor et al, 2022 ; Marcusso et al, 2022 ). Many studies have related within and between canopy epiphyte assemblages to environmental and structural properties of the host tree ( Morales-Linares et al, 2020 ; Victoriano-Romero et al, 2020 ) and also focused more recently on epiphyte-host tree commensalistic networks ( Burns, 2007 ; Burns & Zotz, 2010 ; Silva et al, 2010 ; Piazzon, Larrinaga & Santamaría, 2011 ; Ceballos, Chacoff & Malizia, 2016 ; Francisco et al, 2018 ; Francisco et al, 2019 ; Naranjo et al, 2019 ; Zotarelli et al, 2019 ; Cortés-Anzúres et al, 2020 ).…”

Understanding the mechanisms driving community assembly has been a major focus of ecological research for nearly a century, yet little is known about these mechanisms in commensal communities, particularly with respect to their historical/evolutionary components. Here, we use a large-scale dataset of 4,440 vascular plant species to explore the relationship between the evolutionary distinctiveness (ED) (as measured by the ’species evolutionary history’ (SEH)) of host species and the phylogenetic diversity (PD) of their associated epiphyte species. Although there was considerable variation across hosts and their associated epiphyte species, they were largely unrelated to host SEH. Our results mostly support the idea that the determinants of epiphyte colonization success might involve host characteristics that are unrelated to host SEH (e.g., architectural differences between hosts). While determinants of PD of epiphyte assemblages are poorly known, they do not appear to be related to the evolutionary history of host species. Instead, they might be better explained by neutral processes of colonization and extinction. However, the high level of phylogenetic signal in epiphyte PD (independent of SEH) suggests it might still be influenced by yet unrecognized evolutionary determinants. This study highlights how little is still known about the phylogenetic determinants of epiphyte communities.

“…To reinforce regionalization, integrating data from various species groups helps unveil co-evolutionary relationships, predict ecosystem shifts, and enhance our understanding of the region's history and potential future changes [53]. This approach not only aids in delineating phylogenetically informed floristic regions but also deepens our grasp of phytogeographical establishment and identification [54].…”

Floristic regions, conventionally established using species distribution patterns, have often overlooked the phylogenetic relationships among taxa. However, how phylogenetic relationships influence the historical interconnections within and among biogeographic regions remains inadequately understood. In this research, we compiled distribution data for seed plants in Gansu, a region of significant biogeographic diversity located in northwestern China.We proposed a novel framework for floristic regions within Gansu, integrating distribution data and phylogenetic relationships of genera-level native seed plants, aiming to explore the relationship between phylogenetic relatedness, taxonomic composition, and regional phylogenetic delineation. We found that (1) phylogenetic relatedness was strongly correlated with the taxonomic composition among floras in Gansu. (2) The southeastern Gansu region showed the lowest level of spatial turnover in both phylogenetic relationships and the taxonomic composition of floristic assemblages across the Gansu region. (3) Null model analyses indicated nonrandom phylogenetic structure across the region, where most areas showed higher phylogenetic turnover than expected given the underlying taxonomic composition between sites. (4) Our results demonstrated a consistent pattern across various regionalization schemes and highlighted the preference for employing the phylogenetic dissimilarity approach in biogeographical regionalization investigations. (5) Employing the phylogenetic dissimilarity approach, we identified nine distinct floristic regions in Gansu that are categorized into two broader geographical units, namely the northwest and southeast. (6) Based on the phylogenetic graphic regions of China across this area.
