Phylogeny, biogeography, and morphological evolution among and within the Neotropical and Asian clades of Schefflera (Araliaceae)

Gregory Plunkett, Porter Lowry, Pedro Fiaschi, David Frodin & Antoine Nicolas
Schefflera is the largest and most complex genus of Araliaceae, with ~600 described species (and many additional species awaiting formal description), but recent studies indicate that it is polyphyletic, forming five geographically centered clades spread across the major lineages of the family. Significant progress has been made in revising the three smallest clades, but the two largest groups, centered in Asia and the Neotropics, remain poorly understood. To advance our knowledge of these groups, a...

La Amazonía abarca un área de aproximada de 6.8 millones km² situada en la parte norte de América del Sur (Eva et al., 2005). Los bosques húmedos cubren casi el 80% de la Amazonía (5.5 millones de km²) y el restante 20%, está cubierto por bosques secos (1%), bosques inundados (3%), herbazales y matorrales (5%), vegetación escasa (1%), así como por agricultura y áreas urbanas (10%). La región Madre de Dios, ha revelado altos niveles...

Data set from Argentinian plots from: 'Untangling the importance of niche breadth and niche position as drivers of tree species abundance and occupancy across biogeographic regions '. Global Ecology and Biogeography 2020. https://doi.org/10.1111/geb.13139

Data package for 'Untangling the importance of niche breadth and niche position as drivers of tree species abundance and occupancy across biogeographic regions '. Global Ecology and Biogeography 2020. ABSTRACT Despite decades of interest in how ecological niches shape species commonness and rarity at local and regional scales, the relative importance of different niche mechanisms within and across ecosystems remains unresolved. We tested the relative importance of niche breadth (range of environmental conditions where species...

RAD-seq reveals patterns of diversification, hybridization, and the accumulation of reproductive isolation in a clade of partially sympatric, tropical island trees

Alexander Linan, , Allison Miller, George Schatz, Jean Claude Sevathian & Christine Edwards
A common pattern observed in temperate tree clades is that species are often morphologically distinct and partially interfertile but maintain species cohesion despite ongoing hybridization where ranges overlap. Although closely related species commonly occur in sympatry in tropical ecosystems, little is known about patterns of hybridization within a clade over time, and the implications of this hybridization for the maintenance of species boundaries. In this study, we focused on a clade of sympatric trees in...

Weda, a new genus with two new species of Euphorbiaceae-Crotonoideae from Halmahera (North Moluccas, Indonesia) and phylogenetic relationships of the Australasian tribe Ricinocarpeae

Peter Van Welzen, Susana Arias Guerrero, Deby Arifiani, Tjut Bangun, Roderick Bouman, Marcel Eurlings, Iska Gushilman, Peter Philipson, Iris Tabak, Esmée Winkel & Kenneth Wurdack
Two unknown Euphorbiaceae were discovered during the environmental impact study for a proposed nickel mine behind Weda Bay on Halmahera in the North Moluccas (Maluku Utara Province) of Indonesia. Morphological comparisons and molecular phylogenetic analyses using four markers (plastid trnL-F and rbcL, and nuclear ribosomal ITS and ETS) indicated they should be recognized as constituting a new, distinct genus of two species, which are described and illustrated here as Weda fragarioides and W. lutea. The...

Data from: Annual understory plant recovery dynamics in a temperate woodland mosaic during a decade of ecological restoration

J. Leighton Reid, Nels J. Holmberg, Matthew Albrecht, Sandra Arango-Caro, Olivia Hajek, Quinn Long & James Trager
Temperate woodlands are one of the world’s ecosystems in greatest need of ecological restoration, but relatively little is known about their floristic recovery dynamics over decadal timescales. From 2000 to 2012, we monitored understory plant communities in a woodland mosaic in Missouri, USA, as it underwent restoration via prescribed, dormant-season burning and mechanical thinning of red cedar (Juniperus virginiana) and exotic shrubs. Native species richness increased linearly by 36% over this time period, driven primarily...
