Diversity-Elevation Relationships of Vascular Plants in Austral Temperate Ecosystems Are Strata Dependent. [PDF]
We investigated diversity patterns of vascular plants of overstorey and understorey vegetation separately per stratum and the influence of anthropogenic disturbances along two elevational transects with contrasting slope aspects in a temperate rainforest and alpine scrub in southern Chile.

Osmoxylon-like fossils from early Eocene South America: West Gondwana-Malesia connections in Araliaceae. [PDF]
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Toward a phylogenomic classification of magnoliids. [PDF]
Abstract Premise Magnoliids are a strongly supported clade of angiosperms. Previous phylogenetic studies based primarily on analyses of a limited number of mostly plastid markers have led to the current classification of magnoliids into four orders and 18 families. However, uncertainty remains regarding the placement of several families.

Paleobotany reframes the fiery debate on Australia's rainforest edges. [PDF]
Summary The tall eucalypt forests (TEFs) of the Australian tropics are often portrayed as threatened by ‘invasive’ neighboring rainforests, requiring ‘protective’ burning. This framing overlooks that Australian rainforests have suffered twice the historical losses of TEFs and ignores the ecological and paleobiological significance of rainforest margins.

The Neotropical endemic liverwort subfamily Micropterygioideae had circum-Antarctic links to the rest of the Lepidoziaceae during the early Cretaceous. [PDF]
We inferred the position of Micropterygioideae in the molecular phylogeny of the liverwort family Lepidoziaceae for the first time and found circum‐Antarctic links of the subfamily to the rest of the family. Additionally, we estimated the divergence times and inferred the ancestral ranges of the major clades of the family.

The Winteraceae comprise 100 – 130 species in five to nine genera. The genus Zygogynum is currently thought to have a Papuasian-Pacific distribution and is only known from the western Pacific islands (New Caledonia, Vanuatu and the Solomon Islands ...

Winteraceae family consists of 5 genera that are disjunctly distributed in Madagascar, Australasia, Central and South America. Phylogenetic relationships in Winteraceae were reconstructed using the molecular data (ITS-5.8S rDNA and trnL-trnF sequences ...

Do Southeast Asia's paleo‐Antarctic trees cool the planet?
Summary Many tree genera in the Malesian uplands have Southern Hemisphere origins, often supported by austral fossil records. Weathering the vast bedrock exposures in the everwet Malesian tropics may have consumed sufficient atmospheric CO2 to contribute significantly to global cooling over the past 15 Myr.
