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

The Southernmost Known Population of the Monito Del Monte, <i>Dromiciops gliroides</i>. [PDF]

Ecol Evol
A range extension for a relict south American marsupial. ABSTRACT The monito del monte (genus Dromiciops) is a small arboreal marsupial endemic to the temperate rainforests of southern South America, and the sole extant representative of the order Microbiotheria. This lineage, considered a sister group of Australian marsupials, is of great evolutionary,

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.

Climate and Nothofagus pumilio Establishment at Upper Treelines in the Patagonian Andes [PDF]

Frontiers in Earth Science, 2018
Debido a su sensibilidad climática, la línea arbórea superior ofrece una oportunidad única para documentar las variaciones en la dinámica forestal en respuesta al cambio climático actual. En general, se acepta que la expansión de la línea arbórea superior está limitada por las bajas temperaturas.

Relationships among livestock, structure, and regeneration in Chilean Austral Macrozone temperate forests

Trees, Forests and People, 2023
A Macrozone is a socioecological region with shared geographic and demographic characteristics. Within the Chilean Austral Macrozone (43° to 56° SL), the native temperate forests serve as a crucial resource, offering multiple ecosystem services to local ...

Pumilio binds para mRNA and requires nanos and brat to regulate sodium current in drosophila motoneurons [PDF]

, 2008
Homeostatic regulation of ionic currents is of paramount importance during periods of synaptic growth or remodeling. Our previous work has identified the translational repressor Pumilio (Pum) as a regulator of sodium current (INa) and excitability in ...

Micropropagación de Nothofagus pumilio (Poepp. et Endl.) Krasser

Bosque, 1997
Nothofagus pumilio is the most important forest species in South Patagonia. The present work was carried out to determine the suitable cultural conditions for in vitro propagation through shoot culture of saplings and a mature tree. The days after sprouting and the presence of the bud scales were critical for culture initiation.

Interannual variations in primary and secondary growth of Nothofagus pumilio and their relationships with climate [PDF]

Trees, 2014
The aim of this study is to evaluate the relationships between primary and secondary growth as well as the influences of climate variations on both types of growth. The relationships between apical (or primary) and radial (or secondary) growth, and climatic influences on both types of growth, were evaluated for Nothofagus pumilio ...

Regulation of neuronal excitability through pumilio-dependent control of a sodium channel gene [PDF]

, 2004
Dynamic changes in synaptic connectivity and strength, which occur during both embryonic development and learning, have the tendency to destabilize neural circuits.
