A multicriteria decision making approach to prioritise vascular plants for species-based conservation
There is a growing demand for species-based conservation to be strategic and deliver the greatest possible benefits for the money and resources invested. There is no global consensus on what constitutes an important species, but many biodiversity conservation initiatives prioritise the most rare, unique, vulnerable and/or useful as deserving attention....Liu, Udayangani ; Kenney, Siobhan ; Breman, Elinor ; Cossu, Tiziana

A broader circumscription of Bulbostylis including Nemum (Abildgaardieae: Cyperaceae)
Phylogenetic hypotheses and morphological characterizations of genera in the Abildgaardieae have suggested that current generic circumscriptions are not monophyletic. We here provide an updated phylogenetic hypothesis of the Abildgaardieae using nrDNA ITS sequences that continues to support the derivation of Nemum from within the Bulbostylis lineage. We make the nomenclatural...Roalson, Eric ; Prata, Ana ; Mesterhazy, Attila ; Chase, Mark ; Simpson, David …

A customized nuclear target enrichment approach for developing a phylogenomic baseline for Dioscorea yams (Dioscoreaceae)
Premise We developed a target enrichment panel for phylogenomic studies of Dioscorea, an economically important genus with incompletely resolved relationships. Methods Our bait panel comprises 260 low- to single-copy nuclear genes targeted to work in Dioscorea, assessed here using a preliminary taxon sampling that includes both distantly and closely related...Soto Gomez, Marybel ; Pokorny, Lisa ; Kantar, Michael ; Forest, Félix ; Leitch, Ilia …

A benchmark dataset of herbarium specimen images with label data
More and more herbaria are digitising their collections. Images of specimens are made available online to facilitate access to them and allow extraction of information from them. Transcription of the data written on specimens is critical for general discoverability and enables incorporation into large aggregated research datasets. Different methods, such...Dillen, Mathias ; Groom, Quentin ; Chagnoux, Simon ; Güntsch, Anton ; Hardisty, Alex …

A morphometric study of the restinga ecotype of Anacardium occidentale (Anacardiaceae): wild coastal cashew populations from Piauí, Northeast Brazil
The infraspecific taxonomy of wild Anacardium occidentale is little studied. We investigated whether wild populations on coastal dunes in Piauí, Brazil differed from non-wild populations. Ten populations were sampled and twenty one morphological variables were measured. Variation within and between populations was investigated with univariate and multivariate statistics. Dune populations...de Andrade, I ; de Oliveira, Nascimento ; de Sousa, M ; dos Santos, J ; Mayo, S

‘Unknown yellow’: Pibiria, a new genus of Passifloraceae with a mixture of features found in Passifloroideae and Turneroideae
In 1993, a shrub with yellow flowers reminiscent of but obviously distinct from Turnera was found near Mabura Hill in central Guyana, which was recollected in 2000. This paper offers a morphological description including leaf and wood anatomy and pollen morphology in addition to a phylogenetic analysis based on plastid...Maas, Paul ; Baas, Pieter ; Christenhusz, Maarten ; Clarkson, James ; Koek-Noorman, Jifke …

Taxonomic Synopsis of Eriosema (Leguminosae: Papilionoideae, Phaseoleae) in Brazil
Eriosema is a pantropical genus occurring mostly in savanna vegetation and grasslands of tropical environments, with approximately 150 species and two centers of diversity, one in Africa with about 110 species, and the other in the Neotropics with about 40 species. Considering the large number of Eriosema taxa in Brazil,...Cândido, , Elisa ; de Vargas, Wanderleia ; Bezerra, Luísa ; Mansano, Vidal ; Vatanparast, Mohammad …

Building mountain biodiversity: Geological and evolutionary processes
Mountain regions are unusually biodiverse, with rich aggregations of small-ranged species that form centers of endemism. Mountains play an array of roles for Earth’s biodiversity and affect neighboring lowlands through biotic interchange, changes in regional climate, and nutrient runoff. The high biodiversity of certain mountains reflects the interplay of multiple...Rahbek, Carsten ; Borregaard, Michael ; Antonelli, Alexandre ; Colwell, Robert ; Holt, Ben …
