Flora vascular en plantaciones dominadas por Coihue (Nothofagus dombeyi) y Raulí (Nothofagus alpina)

Gayana: Botanica
El presente estudio tuvo como objetivo conocer la riqueza y diversidad florística vascular en plantaciones dominadas por Coihue (Nothofagus dombeyi) y Raulí (Nothofagus alpina), ubicadas entre los 37º15’ y 41º15’ S, tanto en las cordilleras de los Andes

Morfología y Anatomía del Ápice Caulinar de Nothofagus dombeyi (Nothofagaceae) a lo largo de un año Morfology and anatomy of the shoot apex of Nothofagus dombeyi (Nothofagaceae) along a year

Boletín de la Sociedad Argentina de Botánica, 2006
En el presente estudio se evaluó la posible variación anual de la morfología y la anatomía del ápice caulinar de coihue, Nothofagus dombeyi (Nothofagaceae). A partir de muestras tomadas a lo largo de un año calendario, se realizaron cortes longitudinales

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia. [PDF]

Ecol Evol
Ectomycorrhizal fungi play essential roles in nitrogen cycling and plant nutrient uptake at high latitudes. However, they have disproportionately been studied in boreal forests dominated by evergreen conifers. We characterized ectomycorrhizal associations and the nitrogen economy of co‐occurring deciduous and evergreen angiosperms from the genus ...

Recurrent hot droughts cause persistent legacy effects in a temperate Scots Pine forest. [PDF]

Plant Biol (Stuttg)
A series of hot drought events caused persistent legacy effects in a Scots Pine forest, with severe negative impacts on ecosystem carbon fluxes. Abstract Recent hot‐dry events have caused significant impacts and legacy effects in temperate ecosystems. Here, we investigate legacy effects of the 2018 hot drought on a Pinus sylvestris L.

The functional mechanism behind the latitudinal pattern of liana diversity: Freeze–thaw embolism reduces the ecological performance of liana species

Ecology and Evolution, Volume 13, Issue 9, September 2023., 2023
Establish the functional mechanism behind the loss of liana diversity along a latitudinal temperature gradient. Abstract There is a strong decrease in liana diversity along latitudinal and altitudinal gradients at a global scale, and there is a marked difference in liana diversity between tropical and temperate ecosystems.

Effects of artificial damage on the branching pattern of Nothofagus dombeyi (Nothofagaceae) [PDF]

Annals of Forest Science, 2006
The effects of artificial damage on the branching pattern were studied for a natural population of Nothofagus dombeyi trees. In four independent experiments, leaves, buds, distal internodes and/or nodes were clipped from main-branch shoots. The sizes of shoots close to the site of damage were compared with those of control shoots.

The delayed effect of climatic conditions on pre‐fledging nestling haematocrit in a suboscine species in Patagonia

Journal of Avian Biology, Volume 2023, Issue 9-10, September/October 2023., 2023
Haematocrit, the proportion of blood comprising erythrocytes, is often used as a proxy of individual condition. Nestling haematocrit is influenced by several factors but ambient temperature is generally agreed as a key driver. It is unclear which day(s) in embryonic or nestling development are most influential in determining pre‐fledgling haematocrit ...

Phylogenetic relationships and time-calibration of the South American fossil and extant species of southern beeches (Nothofagus) [PDF]

Acta Palaeontologica Polonica, 2018
The genus Nothofagus is considered as one of the most interesting plant genera, not only for the living species but also due to the fossil evidence distributed throughout the Southern Hemisphere. Early publications postulated a close relationship between

Changes in the natural dynamics of Nothofagus dombeyi forests

Ecosphere, 2017
Drought-induced episodes of tree mortality can determine forest dynamics and structure, particularly in forests dominated by single species. Short- and mid-term climate projections indicate that strong changes in annual precipitation may strike more often in northern Patagonia.

Effects of solar radiation on regeneration patterns in a Nothofagus dombeyi (Mirb.) Oerst. old-growth forest in Chile’s central-southern Andes

Gayana: Botanica, 2019
Nothofagus species behave like early successional species that recolonize open sites after of regular and large-scale disturbances. This study analyzed the effects of light regimes on patterns of advanced regeneration dynamics, growth in diameter ...
