Plant invasion and naturalization are influenced by genome size, ecology and economic use globally.
Human factors and plant characteristics are important drivers of plant invasions, which threaten ecosystem integrity, biodiversity and human well-being. However, while previous studies often examined a limited number of factors or focused on a specific invasion stage (e.g., naturalization) for specific regions, a multi-factor and multi-stage analysis at the global...Guo, Kun ; Pyšek, Petr ; van Kleunen, Mark ; Kinlock, Nicole L. ; Lučanová, Magdalena …

The bii4africa dataset of faunal and floral population intactness estimates across Africa’s major land uses.
Sub-Saharan Africa is under-represented in global biodiversity datasets, particularly regarding the impact of land use on species’ population abundances. Drawing on recent advances in expert elicitation to ensure data consistency, 200 experts were convened using a modified-Delphi process to estimate ‘intactness scores’: the remaining proportion of an ‘intact’ reference population... -

Diversity and distribution of ferns and clubmosses in the eastern canyons of Isalo National Park, Madagascar.
– In contrast to the flowering plants, the pteridophyte flora of Madagascar is still understudied. While several studies have been published on the eastern and central parts of the island, there are currently few works dedicated to the pteridophytes of southwestern Madagascar. The aim of this work is to increase... -

The Resurrection of Ancistrocladus pachyrrhachis (Ancistrocladaceae) from Liberia.
Ancistrocladus pachyrrhachis (Ancistrocladaceae), described in 1950, is resurrected and compared with A. barteri, the species with which it was synonymised in 2005.

Notes on morphology, taxonomy and geographic distribution of Apeiba (Malvaceae, Grewioideae) in the Brazilian Amazon.
ABSTRACT Apeiba (Malvaceae, Grewioideae) is an important component of the Neotropical flora, but taxonomic knowledge of its species is limited, particularly within the Amazon region. This study aimed to provide an updated taxonomic treatment of Apeiba native to Brazil, with focus on Amazonian collections. Species of Apeiba are trees with...Secco, Ricardo de S. ; Colli-Silva, Matheus ; Santos Souza, Júlio

Keita (Aptandraceae-Olacaceae s.l.), a new genus for African species previously ascribed to Anacolosa, including K. deniseae sp. nov., an Endangered submontane forest liana from Simandou, Republic of Guinea.
We show that the two continental African species previously ascribed to the genus , differ in so many architectural, floral and vegetative characters from the remaining species of the genus (which occur from Madagascar to the western Pacific, including the type) that they clearly represent a separate genus. The African... -

Aging-Induced Reduction in Safflower Seed Germination via Impaired Energy Metabolism and Genetic Integrity Is Partially Restored by Sucrose and DA-6 Treatment.
Seed storage underpins global agriculture and the seed trade and revealing the mechanisms of seed aging is essential for enhancing seed longevity management. Safflower is a multipurpose oil crop, rich in unsaturated fatty acids that are at high risk of peroxidation as a contributory factor to seed aging. However, the... -

Description of five new species of the Madagascan flagship plant genus Ravenala (Strelitziaceae).
Madagascar’s emblematic traveller’s tree is a monospecific genus within Strelitziaceae, the family of the South African bird of paradise. Until now, this endemic genus consisted of a single species: Sonn., which is grown everywhere in the tropics as an ornamental plant. The plant is immediately recognizable for its huge fan-forming... -

Pharmaceutical Terminology in Ancient and Medieval Time – andrachne, chrysocolla and Others.
Ancient and medieval pharmacological and medical texts contain a substantial amount of plant and mineral names. In some cases, the identification is straightforward. But for the majority of the data, we are unable to identify these ingredients with high certainty. In this paper, we discuss a selection of plant and... -

Global conservation status of the jawed vertebrate Tree of Life.
Human-driven extinction threatens entire lineages across the Tree of Life. Here we assess the conservation status of jawed vertebrate evolutionary history, using three policy-relevant approaches. First, we calculate an index of threat to overall evolutionary history, showing that we expect to lose 86–150 billion years (11–19%) of jawed vertebrate evolutionary...Gumbs, Rikki ; Scott, Oenone ; Bates, Ryan ; Böhm, Monika ; Forest, Félix …

Field observations, discriminant analyses of morphological characters and phylogenetic inference based on molecular data led to the recognition of a new species of tree. This new taxon is distinct for having broadly obovate leaves, white petals, bright yellow flower resin and relatively...Luján, Manuel ; Paolini-Ruiz, Jorge ; Sanoja, Elio ; Rojas, Cherry A. ; Ely, Francisca

Taxonomic characterisation of the Regianum clade (genus Tuber) and the trait evolution of spore size among true truffles.
The genus comprises ectomycorrhizal fungal species producing belowground ascomata, including the gastronomically most prominent hypogeous fungi. Since the discovery and description of new species are ongoing, the proportion of undescribed species can be considerable and the taxonomy of the genus goes often through changes. The taxonomy of the genus would... -

A new R package to parse plant species occurrence records into unique collection events efficiently reduces data redundancy.
Biodiversity data aggregators, such as Global Biodiversity Information Facility (GBIF) suffer from inflation of the number of occurrence records when data from different databases are merged but not fully reconciled. The ParseGBIF workflow is designed to parse duplicate GBIF species occurrence records into unique collection events (gatherings) and to optimise... -
