Regeneration of Nothofagus dombeyi (Mirb.) Ørst. in little to moderately disturbed southern beech forests in the Andes of Patagonia (Argentina)

Forest Ecosystems, 2023
Natural forests and stands subjected to little to moderate human impact are continuously declining worldwide and with these, their biodiversity and ecosystem services. Many Nothofagus forests in the south of the South American continent are in a pristine

Variación estacional de la micoflora en la hojarasca de Nothofagus DombeyI

Revista del Museo de La Plata
Los organismos degradadores, hongos y bacterias, cumplen una función vital en los ecosistemas de bosque, manteniendo el reciclado de la materia. Aquellos actúan sobre los detritos vegetales y animales alimentando un proceso que conduce a la formación de ...

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 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 ...

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

, 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,

Correlated evolution in an ectomycorrhizal host–symbiont system

New Phytologist, Volume 238, Issue 3, Page 1215-1229, May 2023., 2023
Summary Mechanisms of diversification in fungi are relatively poorly known. Many ectomycorrhizal symbionts show preference for particular host genera or families, so host–symbiont selection may be an important driver of fungal diversification in ectomycorrhizal systems.

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

Nonstructural carbohydrates predict survival in saplings of temperate trees under carbon stress

Functional Ecology, Volume 36, Issue 11, Page 2806-2818, November 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nonstructural carbohydrates (NSCs) mediate plant survival when the plant's carbon (C) balance is negative, suggesting that NSCs could predict plant survival under C stress.
