Societal Impact Statement There is increasing awareness that plants and fungi, as natural solutions, can play an important role in tackling ongoing global environmental challenges. We illustrate how understanding current projected threats to fungi necessary manage mitigate risks, while building of gaps bias assessment coverage essential adequately prioritize conservation efforts. highlight the state art science point methods future studies needed species extinction.

Abstract Aim To examine whether the tree flora of Atlantic forest northeastern Brazil has experienced detectable taxonomic homogenization via proliferation native pioneer species in response to habitat loss and fragmentation. Location Biotic (BH) was examined across northeast Brazil, i.e. a 56,000 km 2 piece tropical distinct centre endemism South America. Methods We assessed dataset consisting 5122 records compared similarity floras from 12 semi‐natural sub‐regions between two time periods:...
Summary More than 70% of all vascular plants lack conservation status assessments. We aimed to address this shortfall in knowledge species extinction risk by using the World Checklist Vascular Plants generate first comprehensive set predictions for a large clade: angiosperms (flowering plants, c. 330 000 species). used Bayesian Additive Regression Trees (BART) predict predictors relating range size, human footprint, climate, and evolutionary history applied novel approach estimate...
Abstract Understanding how plant life history affects species vulnerability to anthropogenic disturbances and environmental change is a major ecological challenge. We examined vegetation type, growth form, geographic range size relate extinction risk throughout the Brazilian Atlantic Forest domain. used database containing species‐level information of 6,929 angiosperms within 112 families molecular‐based working phylogeny. decision trees, standard regression, phylogenetic regression explore...
Abstract Lake ice cover is declining globally with important implications for lake ecosystems. Ice loss studies often rely on small numbers of lakes long‐term data. We analyzed variation and trends in phenology from 1213 over 74 yr (1949–2022) Minnesota (USA), during which duration declined at a rate 2 d per decade (14 total) became more variable. Despite phenology, just 10–20% differed statewide phenological trends. Accounting synchronous annual estimating long time periods (e.g., > 40...

Abstract Aim To provide novel evidence on the average impact of climate and land use changes habitat suitability for tropical plants to test previous conclusions relative importance these two drivers in shaping future availability plant species. Location Brazil’s Atlantic Forest domain. Time period Plant occurrences recorded between 1960 2014. Baseline from 2000 2015. Projected scenarios 2041–2060 2050. Major taxa studied Angiosperms. Methods We modelled 2,232 species angiosperms domain,...
Summary More than 70% of all vascular plants lack conservation status assessments. We aimed to address this shortfall in knowledge species extinction risk by using the World Checklist Vascular Plants generate first comprehensive set predictions for a large clade: angiosperms (flowering plants, ∼330,000 species). used Bayesian Additive Regression Trees (BART) predict predictors relating range size, human footprint, climate, and evolutionary history applied novel approach estimate uncertainty...
Species’ geographic range size is arguably the single most important predictor of vulnerability to extinction and a key metric in ecology. Despite this, patterns specific variation their underlying reasons are still poorly understood. For example, hypotheses on how evolutionary history affects have scarcely been tested. To address these questions, we focused Brazil's Atlantic Forest flora, one species‐rich world, relatively well‐known highly threatened. We investigated whether lineages’...
Community assembly persists as a key topic in ecology due to the complex variation relative importance of forces and mechanisms across spatio-temporal scales ecosystems. Here we address forest–savanna vegetation mosaic Brazilian Atlantic forest examine role played by soil attributes determinants community organization at landscape spatial scale. We examined plant assemblage 23 plots savanna 1600 km2 exposed same climatic conditions region northeast Brazil. Assemblage included species...
Assessing species' extinction risk is vital to setting conservation priorities. However, assessment endeavors, such as those used produce the IUCN Red List of Threatened Species, have significant gaps in taxonomic coverage. Automated (AA) methods are gaining popularity fill these gaps. Choices made developing, using, and reporting results AA could hinder their successful adoption or lead poor allocation resources. We explored how choice data cleaning type level, group, training sample,...
Abstract Protected areas (PA) in biodiversity hotspots face the challenge of monitoring large numbers locally rare and threatened plant species at times with limited budgets. Prioritising according to their local extinction risk could help PA managers decide which monitor. However, there is often very little information available on occurrence PA. Because this, rely national or global Red List for prioritising level. Here, we evaluate effectiveness using prioritisation examine robustness...
Abstract Aim Angiosperm epiphytes have long been reported to larger geographic ranges than terrestrial species, despite evidence of their outstanding diversity and endemism. This apparent contradiction calls for further investigation epiphytes' poorly understood range size patterns. Here, we address the question whether different vulnerability extinction species. Location The Atlantic Forest Brazil, a global centre tropical epiphyte with relatively well‐known flora, where can estimate large...
Abstract Epiphytes have long been considered to larger geographic range sizes than terrestrial plants, yet evidence for this claim comes from studies at restricted and taxonomic scales is contrary that of some recent studies. We examined if epiphytes or smaller plants tested epiphytism a likely driver differences in size globally across angiosperms. integrated global datasets on angiosperm taxonomy, distribution, lifeform calculate three metrics. there were significant mean between...
Extinction risk assessments are increasingly important to many stakeholders (Bennun et al. 2017) but there remain large gaps in our knowledge about the status of species. The IUCN Red List Threatened Species (IUCN 2019, hereafter List) is most comprehensive assessment extinction risk. However, it includes just 7% all vascular plants, while 18% assessed animals lack sufficient data assign a conservation status. wide availability species occurrence information through digitised natural history...
Assessing species’ extinction risk is vital to setting conservation priorities.

Epiphytes have long been reported to larger geographic ranges than terrestrial species, despite evidence of their outstanding diversity and endemism. This apparent contradiction calls for further investigation epiphytes’ poorly understood range size patterns. Here, we address the question whether epiphytes species in Atlantic Forest Brazil, a global centre epiphyte diversity. In contrasting extent occurrence area occupancy 12,679 non-epiphytes at varying taxonomic scales, found that among...
