Diversity-Elevation Relationships of Vascular Plants in Austral Temperate Ecosystems Are Strata Dependent. [PDF]

Ecol Evol
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.

Toward a phylogenomic classification of magnoliids. [PDF]

Am J Bot
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.

Molecular insights into volatile organic compound sensing and signaling in plants. [PDF]

Plant J
SUMMARY Plants interact with their surrounding environment through the perception of a vast and structurally diverse array of volatile organic compounds (VOCs); however, the molecular mechanisms involved remain mostly unknown. Despite the large number of VOCs emitted and perceived by plants, only a small number of phylogenetically distinct, but often ...

Do Southeast Asia's paleo‐Antarctic trees cool the planet?

New Phytologist, Volume 239, Issue 5, Page 1556-1566, September 2023., 2023
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.

The first Gondwanan Euphorbiaceae fossils reset the biogeographic history of the Macaranga‐Mallotus clade

American Journal of Botany, Volume 110, Issue 5, May 2023., 2023
Abstract Premise The spurge family Euphorbiaceae is prominent in tropical rainforests worldwide, particularly in Asia. There is little consensus on the biogeographic origins of the family or its principal lineages. No confirmed spurge macrofossils have come from Gondwana.

The Neotropical endemic liverwort subfamily Micropterygioideae had circum-Antarctic links to the rest of the Lepidoziaceae during the early Cretaceous. [PDF]

Ecol Evol
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.
