9-Deoxymuzigadial, a Sesquiterpene Isolated From Drimys brasiliensis (Winteraceae), Displays Reduced Cytotoxicity In Vitro and Modulates Leukocyte Activity and Fibrogenesis In Vivo. [PDF]

Chem Biodivers
ABSTRACT The aims of this study were to investigate in vitro cytotoxic potential and the effects of daily administration during the inflammatory response induced by sponge implants in mice of the sesquiterpene 9‐deoxymuzigadial (9‐DOM), isolated from Drimys brasiliensis (Winteraceae).

Distribution of Drimane Sesquiterpenoids and Tocopherols in Liverworts, Ferns and Higher Plants: Polygonaceae, Canellaceae and Winteraceae Species

Natural Product Communications, 2012
The liverwort, Porella vernicosa complex produces a very hot tasting polygodial, a drimane-type sesquiterpene dialdehyde. The same compound has been isolated from two ferns, Thelypteris hispidula and Blechnum fluviatile , as well as from the higher ...

Assessing the diet and seed dispersal ability of non-native sambar deer (Rusa unicolor) in native ecosystems of south-eastern Australia. [PDF]

Ecol Evol, 2023
Understanding the influence of non‐native herbivores on ecosystems through dietary foraging and seed dispersal requires multiple methodologies. In south‐eastern Australia, sambar deer (Rusa unicolor) are rapidly expanding in range and placing native ecosystems at risk through browsing and as vectors for seed dispersal.

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.

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 ...

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.

Epidermal leaf characters of the Winteraceae

, 1973
Leaf epidermal features (mostly studied in cuticular macerations) of 146 specimens, belonging to c. 33 species of all the 6 genera of the Winteraceae are described in detail. Typical for most representatives is the occurrence of alveolar material of cutinaceous nature overlying the cuticle proper, and usually occluding the stomata. Special attention is

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.

Paleobotany reframes the fiery debate on Australia's rainforest edges. [PDF]

New Phytol
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.

Osmoxylon-like fossils from early Eocene South America: West Gondwana-Malesia connections in Araliaceae. [PDF]

Am J Bot
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.
