Speciation in Howea palms occurred in sympatry, was preceded by ancestral admixture, and was associated with edaphic and phenological adaptation
Howea palms are viewed as one of the most clear-cut cases of speciation in sympatry. The sister species H. belmoreana and H. forsteriana are endemic to the oceanic Lord Howe Island, Australia, where they have overlapping distributions and are reproductively isolated mainly by flowering time differences. However, the potential role...Osborne, Owen ; Ciezarek, Adam ; Wilson, Trevor ; Crayn, Darren ; Hutton, Ian …

New circumscription, morphology and synopsis of Chamaecrista sect. Chamaecrista ser. Coriaceae (Leguminosae)
A new circumscription of Chamaecrista sect. Chamaecrista ser. Coriaceae is presented based on the results of molecular and morphological analyses. The series is monophyletic upon exclusion of three species that were included within it by Irwin and Barneby. Morphological variation within the series is discussed. Characters previously neglected, such as...Rando, Juliana Gastaldello ; Pirani, José Rubens ; Cota, Matheus Martins Teixeira ; Lewis, Gwilym Peter

Megaphylogeny resolves global patterns of mushroom evolution
Mushroom-forming fungi (Agaricomycetes) have the greatest morphological diversity and complexity of any group of fungi. They have radiated into most niches and fulfil diverse roles in the ecosystem, including wood decomposers, pathogens or mycorrhizal mutualists. Despite the importance of mushroom-forming fungi, large-scale patterns of their evolutionary history are poorly known,...Varga, Torda ; Krizsán, Krisztina ; Földi, Csenge ; Dima, Bálint ; Sánchez-García, Marisol …

Opportunities and challenges for an Indonesian forest monitoring network
Permanent sampling plots (PSPs) are a powerful and reliable methodology to help our understanding of the diversity and dynamics of tropical forests. Based on the current inventory of PSPs in Indonesia, there is high potential to establish a long-term collaborative forest monitoring network. Whilst there are challenges to initiating such...Brearley, Francis Q. ; Adinugroho, Wahyu C. ; Cámara-Leret, Rodrigo ; Krisnawati, Haruni ; Ledo, Alicia …

Polyploidy does not control all: Lineage‐specific average chromosome length constrains genome size evolution in ferns
Recent studies investigating the evolution of genome size diversity in ferns have shown that they have a distinctive genome profile compared with other land plants. Ferns are typically characterized by possessing medium‐sized genomes, although a few lineages have evolved very large genomes. Ferns are different from other vascular plant lineages...Liu, Hong‐Mei ; Ekrt, Libor ; Koutecky, Petr ; Pellicer, Jaume ; Hidalgo, Oriane …

A synopsis of Polysphaeria (Rubiaceae) in Mozambique, including two new species
The genus Polysphaeria is investigated in Mozambique based on detailed morphological studies of herbarium specimens, resulting in the recognition of two new species. The first, P. ribauensis, is based on Kraussia sp. A of Flora Zambesiaca and is endemic to the Ribáuè Mountains of Nampula Province. The second, P. harrisii,...Darbyshire, Iain ; Langa, Clayton ; Romeiras, Maria

A revision of the Crepidorhopalon whytei complex (Linderniaceae) in eastern Africa
The Crepidorhopalon whytei (Linderniaceae) species complex is revised using morphological analyses. Based primarily on variations in indumentum, floral morphology, corolla colour and seed morphology, four species are formally recognised within this group in eastern Africa. Crepidorhopalon whytei s.str. is widespread in the highlands of eastern Africa, extending from South Sudan...Darbyshire, Iain ; Wursten, B. ; Luke, Q. ; Fischer, E.

Information gaps in indigenous and local knowledge for science-policy assessments
The need to understand nature’s contributions to people and across a broad spectrum of cultures and ecosystems is increasingly advocated in science assessments and policy decision-making for sustainability. However, for services such as food and medicine, gaps in existing studies on indigenous and local knowledge may preclude inclusive assessments. Here,...Cámara-Leret, Rodrigo ; Dennehy, Zoe
