Biased-corrected richness estimates for the Amazonian tree flora
Amazonian forests are extraordinarily diverse, but the estimated species richness is very much debated. Here, we apply an ensemble of parametric estimators and a novel technique that includes conspecific spatial aggregation to an extended database of forest plots with up-to-date taxonomy. We show that the species abundance distribution of Amazonia...ter Steege, Hans ; Prado, Paulo I. ; Lima, Renato A. F. de ; Pos, Edwin ; de Souza Coelho, Luiz …

Plant traits and vegetation data from climate warming experiments along an 1100 m elevation gradient in Gongga Mountains, China
Functional trait data enhance climate change research by linking climate change, biodiversity response, and ecosystem functioning, and by enabling comparison between systems sharing few taxa. Across four sites along a 3000–4130 m a.s.l. gradient spanning 5.3 °C in growing season temperature in Mt. Gongga, Sichuan, China, we collected plant functional trait and...Vandvik, Vigdis ; Halbritter, Aud H. ; Yang, Yan ; He, Hai ; Zhang, Li …

New directions in pollinator research: diversity, conflict and response to global change
Interactions between pollinators and their plant hosts are central to maintaining global biodiversity and ensuring our food security. In this special issue, we compile reviews that summarize existing knowledge and point out key outstanding research areas to understand and safeguard pollinators, pollinators–host plant interactions and the pollination ecosystem services they...Scott-Brown, Alison ; Koch, Hauke

Museomics Unveil the Phylogeny and Biogeography of the Neglected Juan Fernandez Archipelago Megalachne and Podophorus Endemic Grasses and Their Connection With Relict Pampean-Ventanian Fescues
Oceanic islands constitute natural laboratories to study plant speciation and biogeographic patterns of island endemics. Juan Fernandez is a southern Pacific archipelago consisting of three small oceanic islands located 600–700 km west of the Chilean coastline. Exposed to current cold seasonal oceanic climate, these 5.8–1 Ma old islands harbor a... -

Evidence of large Anacardiaceae trees from the Oligocene–early Miocene Santiago Formation, Azuero, Panama
We have poor knowledge of the plants that inhabited Central America during the Cenozoic. One of the families with a rich fossil record worldwide, especially for the Oligocene and Miocene epochs is Anacardiaceae. Llanodelacruzoxylon sandovalii gen. et sp. nov. is the first formal record of a fossil wood of Anacardiaceae...Rodríguez-Reyes, Oris ; Estrada-Ruiz, Emilio ; Gasson, Peter

Advancing biodiversity assessments with environmental DNA: Long‐read technologies help reveal the drivers of Amazonian fungal diversity
Fungi are a key component of tropical biodiversity. However, due to their inconspicuous and largely subterranean nature, they are usually neglected in biodiversity inventories. The goal of this study was to identify the key determinants of fungal richness, community composition, and turnover in tropical rainforests. We tested specifically for the... -

Conserving orthodox seeds of globally threatened plants ex situ in the Millennium Seed Bank, Royal Botanic Gardens, Kew, UK: the status of seed collections
We reviewed the status of orthodox seed collections of globally threatened plants conserved in − 20 °C long-term storage at the Millennium Seed Bank, Royal Botanic Gardens, Kew, UK in terms of their geographic and bioclimatic representativeness, taxonomic and genetic diversity, quality and physiological status. The comprehensive dataset used spans... -

Characterization of secondary metabolites from the berries of Ziziphus mucronata and their antioxidant properties
Ziziphus mucronata is a medicinal plant used traditionally for treating various diseases. The antioxidant assay for the crude extracts obtained from the berries of Ziziphus mucronata was carried out using DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Purified antioxidant compounds were obtained by chromatographic methods and were subjected to structure elucidation using nuclear magnetic...Parkar, Fasahat ; Njue, Alice Wanjiku ; Langat, Moses Kiprotich ; Omolo, Josiah Ouma

Absolute Configuration of Alkaloids from Uncaria longiflora through Experimental and Computational Approaches
The structure elucidation of three new alkaloids named isoformosaninol (1), formosaninol (2), and longiflorine (3), isolated from the leaves of Uncaria longiflora var. pteropoda (Miq.) Ridsdale, along with their biosynthetic pathways are discussed. Their absolute structures were determined through a combination of physical data interpretation and quantum chemical calculations using...
