The climate in southern Patagonia is heavily influenced by the Southern Westerly Winds (SWW). Therefore, reconstructions from this region are valuable for our understanding of temporal dynamics atmospheric circulation Hemisphere. In study a sedimentary record shallow lake Laguna Amalia – located semiarid Fuegian steppe Tierra del Fuego (53°S) was used to how hydroclimate has changed over last ~7100 years. Our interpretations rely on combination pollen, diatoms, total organic carbon,...
Palynological studies have been performed in order to increase knowledge of relations between present vegetation and fungal biota. The analysis modern analogues will help improve the palaeoenvironmental reconstructions fossil sequences from Isla Grande de Tierra del Fuego. A total 24 taxa found, described illustrated. Surface samples were collected different communities developed on island: steppe, Nothofagus forest–steppe ecotone forest. steppe is characterised by a predominance Poaceae...
Palaeoecological inferences from the analysis of fungal microfossils a mire in Tierra del Fuego, Argentina. This paper presents remains recovered fossil peat sequence at La Correntina (S 54° 33´ - W 67°), located central part Isla Grande de Newly recognised have distinctive morphological features that allow their systematic classification. Representatives Glomeromycota (1), Ascomycota (7), mitosporic fungi (4) and three types spores without taxonomic rank are identified described. study...
The pollen analysis from Cañadón del Toro peat bog (54° 49’ 36” S; 68° 27’ W), located in an interior valley of the Fuegian Andes, provides information about vegetation and climate changes during last 13,500 years. results indicate postglacial development steppe-like under drier colder conditions than today, followed by expansion Nothofagus into after 10,350 cal. yr BP. At this time, predominance a forest-steppe ecotone suggests warm increase moisture availability. By 6,700 BP, closed-canopy...
Resumen. En esta contribucion se exponen los materiales estudiados, las metodologias de muestreo y tecnicas laboratorio utilizadas para el analisis palinologico turberas depositos marinos del Archipielago Tierra Fuego. Asimismo, evaluan limitaciones fortalezas del indicadores biologicos (polen, esporas, microplancton pared organica hongos). Finalmente, presentan tres casos de estudio donde ilustra: i) microfosiles fungicos como complemento para registros polinicos, ii) relaciones entre...
Il progetto di ricerca si e posto come obiettivo lo studio degli insediamenti del Mediterraneo o delle regioni aride semi-aride, che sono distinti in passato per la gestione equilibrata territorio risorse, l’utilizzo patrimonio dei saperi conoscenze locali ottenere “nicchie vitali autosostenibili”. Rientrano nell’ambito questi le oasi. Non tratta, infatti, sorti spontaneamente, doni benevoli della Natura, ma artificialmente creati dalla forza coesione sociale gruppo umano, sottraendo...
The article analyses the solutions and settlement characteristics developed in Mediterranean area, with reference to hypogean rupestrian-dwellings, investigates reasons that have led man prefer forms of subtractive architecture. critical re-reading phenomenon troglodyteism has brought out features rock living so far still little investigated; this is due lack studies able translate energetic behavior these constructive different climatic environmental stresses measurable data.
<p>At 53° S, pans, shallow lakes, lacustrine terraces, perched dunes and paleosols are most of the typical landforms features Fuegian steppe conditioned by climate. They in a cold, semi-arid, oceanic climate highly affected Southern Westerlies winds (SWW).</p><p>During spring early summer, rainfall, snow melting, runoff promote infill pans that become brackish, lakes. When systems filled with water, permanent, high-speed SWW generates...
