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

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,

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 ...

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 ...

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.

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.

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 ...

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.

Fires in rainforests: Quantifying litter bed flammability of cool temperate rainforests in eastern Australia. [PDF]

Am J Bot
Abstract Premise Rainforests are usually too wet to burn, acting as natural barriers to fire spread and as refuges for biodiversity. However, climate change is increasing the risk of fire incursion into rainforests. Our capacity to manage these impacts is hindered by limited research on rainforest flammability.

Pre-Courtship Behavior of Proholopterus chilensis (Coleoptera: Cerambycidae) in a Nothofagus obliqua (Nothofagaceae) Forest [PDF]

Insects
The pre-courtship behavior of Proholopterus chilensis on Nothofagus obliqua trees was recorded for the first time, documenting a putative female “calling” behavior and the consequent male “oriented search,” enabling the description of behavioral units ...

Testing key tenets of pyro-ecophysiology: Indicators of drought response in relation to shoot flammability. [PDF]

Am J Bot
Abstract Premise Relationships between flammability and drought tolerance influence vegetation dynamics during fires. A goal of the emerging subdiscipline of pyro‐ecophysiology is to identify ecophysiological traits that determine live fuel flammability, but empirical studies of these relationships are rare.
