Abstract. We present the case that the fossil record of Nothofagaceae, which is much more extensive in terms of species numbers than the living species, cannot be dealt with in a productive way by the recent proposal by Heenan and Smissen to split Nothofagus into four genera (Phytotaxa, vol. 146, http://dx.doi.org/10.11646/phytotaxa.146.1.1). Such a proposal will render the fossil record almost unworkable, and will lead to a major split in the approach taken by palynologists in comparison to… 
The micro- and megafossil record of Nothofagaceae from South America
TLDR
The fossil record for Nothofagaceae varies according to environmental turnover; when tropical/subtropical floras were present in Patagonia in the Palaeocene–early Eocene, Noth ofagaceae contracted southwards and when open steppes developed in the Miocene of east PatagonIA, Nothsofag Families contracted westward.
Patterns of vegetation in south-central Tasmania : a view based on plant macrofossils
TLDR
This study represents the first quantitative study of macrofossils in Australia for this significant period of environmental change and suggests that allowing for the effects of leaf size and stomatal density in comparisons of vein density is a useful tool for reconstructing the structure of the vegetation from fossil leaves.

Plio-Pleistocene environmental changes shape present day phylogeography of New Zealand’s southern beeches (Nothofagaceae)
ABSTRACT Island ecosystems can be severely affected by climate change as they provide limited opportunities for species to track their habitat. Studying the population dynamics of keystone species
Restoration of southern hemisphere beech (Nothofagaceae) forests: a meta‐analysis
Nothofagus (southern beech) species form a major component of southern hemisphere forests, and in many regions are becoming an important focus for restoration efforts. However, restoration projects
Fifty shades of grey: black beech and mountain beech are genetically distinct but locally admixed
ABSTRACT Nothofagaceae (southern beech) dominate two-thirds of the remaining indigenous forest of New Zealand. Four of the five species indigenous to New Zealand belong to the genus Fuscospora, and
Integrating genetics and suitability modelling to bolster climate change adaptation planning in Patagonian Nothofagus forests
TLDR
A practical spatially- explicit strategy to target conservation interventions distinguishing priority populations for in situ conservation, ex situ conservation in areas where high genetic diversity overlaps with high likelihood of drastic climate change, and potential expansion areas under climate change is proposed.
Characterisation and transferability of transcriptomic microsatellite markers for Nothofagus species
TLDR
A set of 27 transcriptomic microsatellite markers derived from 73 Nothofagus alpina (=N. nervosa) annotated unigenes is provided, revealing low genetic variability, due to the general occurrence of one major allele at each locus, and high specificity, with few alleles shared between species.

A revised infrageneric classification of Nothofagus (Fagaceae)
TLDR
Analysis of cupule morphology, leaf architecture and cuticular morphology of Nothofagus species demonstrates that the existing infrageneric classifications are inaccurate and four subgenera are proposed, based on these characteristics as well as other morphological information.
Using Sequences of rbcL to Study Phylogeny and Biogeography of Nothofagus Species
TLDR
It is tentatively concluded that intercontinental dispersal was possible in the early stages of the evolution of Nothofagus, and the ages of the common ancestors of species in subgenera are derived.
The Phylogenetic Affinities of Nothofagus (Nothofagaceae) Leaf Fossils based on Combined Molecular and Morphological Data
The phylogenetic placements of leaf fossils of Nothofagus (Nothofagaceae) were determined using parsimony analyses of molecular and morphological data for extant species combined with morphological
Revised circumscription of Nothofagus and recognition of the segregate genera Fuscospora , Lophozonia , and Trisyngyne (Nothofagaceae)
TLDR
A new phylogenetic analysis of morphological characters is presented and it is argued that these morphological and molecular differences are sufficient for the four clades of Nothofagaceae to be recognised at the primary rank of genus, and that this classification will be more informative and efficient than the currently circumscribed Noth ofagus with four subgenera.
Ancestral area analysis of Nothofagus (Nothofagaceae) and its congruence with the fossil record
TLDR
These results do not favour Australasia, or parts thereof, being an important area for Nothofagus origin, and identify New Zealand as the second most plausible source area, a result partly supported by the fossil record.
Nothofagus subgenus Brassospora (Nothofagaceae) leaf fossils from New Zealand: a link to Australia and New Guinea?
TLDR
Phylogenetic assessment shows that the leaves of N. palustris are similar to those of Australian Oligocene and Miocene species and may belong to the same clade of Brassospora, a feature that is now only well developed in two New Guinean species.

On the southern slopes of the Mt. Donna Buang massif, Nothofagus cunninghamii occurs within the 60 in. isohyet between 1500 and 4000 ft. The occurrence of N. cunninghamii as an understorey to

The observation that Nothofagus cunninghamii seedlings survive only under canopy gaps in closed Nothofagus forest led to an investigation of the light compensation point for this species. The light
Biogeography of Nothofagus supports the sequence of Gondwana break-up
TLDR
A historical biogeographic analysis of Nothofagus is reported where the reconciled trees between a well-supported Noth ofagus phylogeny and two geological hypotheses are compared: the current view of Gondwana break-up, and the areagram by Linder & Crisp.
NOTHOFAGUS AND PACIFIC BIOGEOGRAPHY
TLDR
This scenario indicates extensive extinction, but also suggests that Australia has a more recent relationship to New Zealand than to southern South America, and suggests that concordant dispersal is an unlikely explanation for this pattern.
