 Nothofagus - Wikipedia, the free encyclopedia
Nothofagus, the southern beeches is a genus of about 35 species of trees native to the temperate oceanic to subtropical Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east and southeast Australia, Tasmania, New Zealand, New Guinea and New Caledonia).
The fruit is a small, flattened or triangular nut, borne in cupules containing 2-7 nuts.

 Australian Systematic Botany Society
Nothofagus is so often used as the key Gondwanan link in biogeographical studies, yet discussions of long distance dispersal in the family are now eroding away the almost mythical status that these plants once held.
The ecology of Australian Nothofagus forests is well documented by Read and Brown, discussing habit and distribution of the three species, the determinants of cool temperate rain forest boundaries and distribution, phenology and reproductive biology, physiological ecology, regeneration and population dynamics, biodiversity of Australian Nothofagus forests, conservation and utilisation.
They suggest that Nothofagus is therefore a key taxon, not only in its contribution to studies of palaeoecology and biogeography, but also in its potential contribution to studies in ecophysiology and ecology.

Nothofagus is one of the oldest genera of flowering plants in the world with a fossil record stretching back 80 million years.
The myrtle, Nothofagus cunninghamii dominates Tasmanian rainforests and is also found in Victoria in the Otway Ranges and the Strezelecki Ranges.
Originally Nothofagus was thought to be distantly related to the beeches, oaks and chestnuts of the Northern Hemisphere (the Fagaceae).

 Mycogeography - Australia and nearby
Nothofagus species are found in New Caledonia and Papua New Guinea, but no Cyttaria species have ever been found in Papua New Guinea or New Caledonia - and not for want of looking by experienced mycologists.
As the Nothofagus species in these two areas are relicts of the ancestral stock, this implies that the ancestor of all current Nothofagus species evolved before Cyttaria.

The genus Nothofagus is represented by approximately forty species that only occur in the Southern Hemisphere.
Forests of Nothofagus were noted as early as the mid- 1800's.
The name Nothofagus means 'false beech', however, Notofagus meaning 'southern beech' may have been more appropriate.

The mixed evergreen –; deciduous forests are dominated by the evergreen Nothofagus betuloides and the deciduous Nothofagus pumilio.
As with the Nothofagus betuloides the Nothofagus pumilio forms ‚krumholz‘ shrubs at the timberline where they intermingle with Nothofagus antarctica, with the latter one becoming dominant eventually.

Nothofagus leaves which were recovered from glacial sediments of the upper Pliocene Sirius Group in the Dominion Range, next to the upper Beardmore Glacier in the Transantarctic Mountains will shortly be described as a new species, tentatively named N.
Nothofagus is a very conservative genus, and the vast literature on living and fossil species suggests that they evolve very slowly, both morphologically and physiologically.
This suggests that not only was Nothofagus present in Antarctica in the mid-Pliocene, but that it had been present continuously up until that time.

 CPD: South America, Site SA45, Temperate Rain Forest, Chile
Nothofagus is lacking in low-elevation forests on Chiloé Island (Donoso, Escobar and Urrutia 1985).
In the Andes, the evergreen angiosperm and mixed angiosperm-gymnosperm forests are eventually succeeded by predominantly deciduous forests comprised of Nothofagus pumilio (picture) and N.
The tree species typical of low-elevation Valdivian rain forest such as Eucryphia cordifolia, Aextoxicon punctatum, Nothofagus alpina, Dasyphyllum diacanthoides and Laurelia sempervirens are reduced in importance or absent, leaving such dominants as Nothofagus dombeyi, Weinmannia trichosperma and Saxegothaea, with abundant Maytenus magellanica, Podocarpus nubigena and Drimys winteri.

Roble mauling, hualo and Nothofagus alessandri do not extend southwards of Maule province, but all other species of Nothofagus which occur in this region, that is coigüe, raulí, roble, lenga and ñirre, extend far to the south, lenga and ñirre actually to Tierra del Fuego.
It was first known as Fagus antarctica until the genus Nothofagus was formed in the middle of the 19th century, by which time it was realized that the beeches of the southern hemisphere were distinct from those of the northern hemisphere.
In the natural forests of this region of Chile, three evergreen and five deciduous species of Nothofagus are estimated as comprising collectively 2/3 of the forests, the remaining 1/3 consisting of a number of other hardwoods, mainly evergreen and eight species of conifers.

 Terrestrial Ecoregions -- Magellanic subpolar forests (NT0402)
The subpolar Nothofagus forests extend along the southern Andes Mountains and the Chilean archipelago from 47ºS to the Cape Horn, including the regions of southern Aisen and Magallanes in Chile.
The northern end of the subpolar Nothofagus forests limit with the Valdivian temperate forests and the eastern part with the Patagonian steppe and the Patagonian grasslands.
Towards the west the region is in contact with the cold southern Pacific Ocean, and on the high Andes vegetation floristically related to the south Andean steppe appears in parts as interrupted islands (Cabrera 1976).

 Fagus, or Deciduous Beech 
Deciduous beech (Nothofagus gunnii), or fagus as it is best-known, a humble tree, usually growing to 2 metres or less.
As Gondwana began to split, Nothofagus (or Southern Beech) was common in what would later become South America, New Zealand, Antarctica, Australia and their near neighbours.
The species of Nothofagus most closely related to fagus are found in South America and New Zealand, strongly supporting the suggestion that Tasmania was formerly linked to those landmasses.

Nothofagus is an ancient genus, which was present in Gondwana and which can be found today in South America, New Zealand, New Guinea, New Caledonia as well as in Australia.
Nothofagus cunninghamii is a rainforest tree which is a major component of cool, temperate rainforests in Tasmania and in southern Victoria (eg.
In areas where it occurs, the rainforest is often dominated by this species, especially in Tasmania where its most common associations are with southern sassafras (Atherosperma moschatum), leatherwood (Eucryphia lucida), 'Horizontal' (Anodopetalum biglandulosum) and also with celery-top pine (Phyllocladus aspleniifolius).

 POLLEN FLOW IN THREE SPECIES OF NOTHOFAGUS IN THE SOUTH OF CHILE
The importance of the genus Nothofagus (Southern beech) for its wood is well known, but this is leading to the threat of extinction due to over-exploitation.
Knowledge of the reproductive processes in Nothofagus is therefore a necessary prerequisite for the preservation of their forest habitat.
The low fertility of the three Nothofagus species could relate to abiotic factors that depress the rate of pollen flow and pollination frequency, although there is not yet enough evidence to assess the full impact of this stochastic element in our model of reproductive efficiency.
