Evolution of Climatic Related Leaf Traits in the Family Nothofagaceae [PDF]

Frontiers in Plant Science, 2018
The current relationship between leaf traits and environmental variables has been widely used as a proxy for climate estimates. However, it has been observed that the phylogenetic relationships between taxa also influence the evolution of climatic ...

Pollen morphology of Nothofagus (Nothofagaceae, Fagales) and its phylogenetic significance

Acta Palaeobotanica, 2016
Nothofagaceae (southern beeches) are a relatively small flowering plant family of trees confined to the Southern Hemisphere. The fossil record of the family is abundant and it has been widely used as a test case for the classic hypothesis that Antarctica,

Neogene plant macrofossils from West Antarctica reveal persistence of Nothofagaceae forests into the early Miocene [PDF]

Communications Earth & Environment
The extinction of woody vegetation in Antarctica remains difficult to constrain due to its fragmented macrofossil record. Despite its long-standing polar position, Antarctica hosted extensive vegetation throughout the Paleogene.

Loose Ends in the Cortinarius Phylogeny: Five New Myxotelamonoid Species Indicate a High Diversity of These Ectomycorrhizal Fungi with South American Nothofagaceae [PDF]

Life, 2021
This paper is a contribution to the current knowledge of taxonomy, ecology and distribution of South American Cortinarius (Pers.) Gray. Cortinarius is among the most widely distributed and species-rich basidiomycete genera occurring with South American ...

New records of mitosporic ascomycetes on Nothofagaceae from Patagonia, Argentina

Boletín de la Sociedad Argentina de Botánica, 2023
Background and aims: The Funga of the Patagonian Nothofagus forests is being studied since the late 19th century, but despite many efforts is still far from being completely known.

Early Eocene Palynofloral Diversity and Nothofagus Niche Modeling Across Western Gondwana [PDF]

Plants
During warm intervals such as the Early Eocene, megathermal vegetation belts expanded toward higher latitudes, displacing mesothermal and microthermal biota.

Complex History of Organellar Introgression in <i>Nothofagus</i> Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection. [PDF]

Ecol Evol
Field photograph of an ancient Nothofagus tree covered with epiphytic lichens in the Patagonian temperate rainforest. This genus serves as a key model for investigating organellar introgression and evolutionary genomics in South America. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of ...

Isolation and characterization of microsatellites for the endangered endemic tree Nothofagus alessandrii (Nothofagaceae) [PDF]

Molecular Biology Reports, 2021
Abstract Nothofagus alessandrii (Nothofagaceae) is one of the most endangered trees from Chile. Despite its conservation status, few molecular markers are available to study its population genetic, connectivity and to assist reproduction programs. Novel polymorphic microsatellites from the genome of N.

Genome duplications, genomic conflict, and rapid phenotypic evolution characterize the Cretaceous radiation of Fagales. [PDF]

J Integr Plant Biol
Fagales show “early burst” model of phenotypic disparification, with morphospace being filled during the early radiation of the Fagales crown and its major families. The elevated levels of phenotypic evolution often correspond to hotspots of gene duplication, whereas species diversification is decoupled from both phenotypic and genomic evolution ...

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.
