Spatial phylogenetics

Journal of Biogeography, Journal Year: 2023, Volume and Issue: 50(8), P. 1454 - 1463

Published: April 5, 2023

Abstract The metric called phylogenetic diversity (PD) has been employed over the last 30 years to add an evolutionary dimension exploration of biodiversity. However, application PD was until recently limited by both technology and methodology. Newly available distributional data from global museum databasing efforts, rapidly increasing coverage DNA sequence improvements computer hardware software have enabled a new ‘big data’ approach PD‐based metrics randomization‐based hypothesis tests ‘spatial phylogenetics’. It can be defined most simply as turning phylogeny into GIS layer, which then used with other layers understand drivers phylodiversity patterns for conservation prioritization. Alpha beta measured using different ways representing branch lengths on given topology (called ‘facets’), each yielding different, interesting perspective that are best viewed in combination. Challenges posed need addressed through careful cleaning gathering further targeted manner. Spatial phylogenetics is only its infancy, showing much promise but many elements awaiting expansion address questions.

Poales are one of the most species-rich, ecologically and economically important orders plants often characterise open habitats, enabled by unique suites traits. We test six hypotheses regarding evolution assembly in closed habitats throughout world, examine whether diversification patterns demonstrate parallel evolution. sampled 42% species obtained taxonomic biogeographic data from World Checklist Vascular Plants database, which was combined with open/closed habitat scored experts. A dated supertree constructed. integrated spatial phylogenetics regionalisation analyses, historical biogeography ancestral state estimations. Diversification result dynamic evolutionary processes that vary across lineages, time space, prominently tropical southern latitudes. Our results reveal recurrent trait transitions species-rich families Poaceae Cyperaceae. Smaller display divergent trajectories.

Strong evidence for latitudinal diversity gradient in mosses across the world

Plant Diversity, Journal Year: 2024, Volume and Issue: 46(4), P. 537 - 541

Published: May 18, 2024

Species richness generally decreases with increasing latitude, a biodiversity gradient that has long been considered as one of the few laws in ecology. This latitudinal diversity observed many major groups organisms. In plants, vascular angiosperms, ferns, and liverworts. However, conspicuous mosses at global or continental scale not until now. Here, we analyze comprehensive data set including moss species each band 20° latitude worldwide. Our results show strongly regardless whether globe is whole different longitudinal segments (e.g., Old World versus New World) are separately. result holds when variation area size among bands taken into account. Pearson's correlation coefficient between -0.99 for both Northern Southern Hemispheres. Because bryophytes an extant lineage early land plants because only include most but also important constituents terrestrial ecosystems, understanding geographic patterns particularly important. The finding our study fills critical knowledge gap.

Anthropogenic and Climatic Variables Jointly Shape the Global Geographical Pattern of Hybrid Plant Diversity

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(6)

Published: May 29, 2025

ABSTRACT The emergence and dispersal of hybrid plants are influenced by a complex interplay climatic, environmental, anthropogenic factors. However, systematic investigations into the global patterns plant diversity their underlying drivers remain scarce. In this study, we compiled comprehensive dataset encompassing 3543 parental species across 274 geographical regions. We analyzed richness, density (SD), hybridization index (which quantifies spatial overlap between hybrids species), along with associations vegetation, variables. Our results reveal that is highest in Europe Japan, whereas Africa, Oceania, Atlantic Ocean exhibit significantly lower diversity. Notably, shows strong correlations both climatic factors, influences playing more dominant role shaping distributions. This particularly evident hybrid‐rich regions such as where locally distributed display reduced species—a pattern likely driven human‐mediated or other activities. findings provide novel insights dynamics plants.

The Influence of Macroclimatic Drivers on the Macrophyte Phylogenetic Diversity in South African Estuaries

Diversity, Journal Year: 2023, Volume and Issue: 15(9), P. 986 - 986

Published: Sept. 1, 2023

The geographical distribution of plants is influenced by macroclimate and dispersal limitations, which have led to lineage isolation subsequent diversification within across various environmental gradients. Macroclimatic variables in coastal wetlands influence plant species lineages biogeographical boundaries. This study aimed determine the macroclimatic on phylogenetic richness South African estuaries. Open-source chloroplast DNA barcoding sequences, climatic data layers were used relationship between richness, MPD, MNTD each bioclimatic variable individually. Temperate diversity positively correlated with temperature whereas subtropical tropical associated increases precipitation. Phylogenetic niche conservatism evident malvids rosids are restricted regions due their physiological adaptations climates. Caryophylales was mostly temperate regions. Poales Alismatales showed wide distributions that likely attributed traits related wind pollination hydrochory, rapid, clonal, high reproductive output, tolerance stressful conditions, intraspecific genetic diversity. findings highlight importance considering factors understanding wetland plants.

Abstract Phylogenetic diversity (PD) is an important measure for identifying areas of conservation. a robust biodiversity metric because it accounts the relationships among species, and not just number species. For this reason, essential element conservation planning. Unfortunately, PD metrics are used by many In case Colombia, which rich in crop wild plant biodiversity, lacks information on genetic resources Crop Wild Relatives (CWR). Due to deforestation agriculture expansion, habitat, where these relatives grow, being reduced at alarming rate could be destroyed altogether. This study focuses comparing species versus PD‐based show advantages using evolutionary We identified new with high endemism CWR establishing comprehensive strategies.

Abstract In this study, we explored the distributions of grass genera in Southern Cone (SC) South America, applying several phylogenetic diversity (PD) metrics and randomization tests. Grasses appear to have been present America since their early evolution as tropical understory species more than 60 Ma. During course evolution, grasses adapted all terrestrial biomes become one most successful plant families on earth. At present, SC contains nearly a wide range humid arid ecoregions. Analyzing 126.514 point occurrences four plastid markers for 148 (91% native genera), found that regions hold highest PD, with no observed bias branch lengths. These results indicate niche conservatism dominates pattern SC. We significantly low PD Dry Chaco Patagonian Steppe, which suggest ecological filtering both warm cold regions. The Steppe also holds longer branches expected by chance, flora is mainly composed distantly related Pooideae northern hemisphere origin.

Published: Dec. 20, 2024

A survey of the moss flora southernmost part Russian Primorsky Territory yielded several intriguing taxa, whose identity is assessed herein based on an integrative morpho-molecular approach. Bellibarbula recurva was previously known in inland Asia only from Sino-Himalayan region and new locality distant earlier ones to ca. 3000 km. Despite morphological uniformity, specimens are remarkably distinct sequences all three obtained DNA markers, approaching American specimen rps4 sequence. Another probable relic, Symblepharis cf. crispifolia, appeared be fairly common southern Territory, where low mountains covered with hard-leaved forests. crispifolia var. brevipes show significant divergence S. s.str., which also has complex phylogenetic structure, obscuring further taxonomic implications. The description illustrations both taxa provided, area, species occur, briefly characterized; it includes numerous thermophilous species, rare or do not occur northwards. Our case study uncovers problem cryptic speciation within distributed temperate climate considered represent relics Arcto-Tertiary flora.
