Acrocladium y Lepyrodon son géneros de musgos pleurocárpicos de distribución austral. En la región fueguina de Argentina crecen las especies A. auriculatum y L. lagurus, como representantes dominantes de estos géneros. Dado que no hay descripcio

The extent of pre-Columbian land use and its legacy on modern ecosystems, plant associations, and species distributions of the Americas is still hotly debated. To address this gap, we present a Holocene palynological record (pollen, spores, microscop

Publikováno v: Journal of Paleolimnology.
A multi-proxy analysis, including pollen, non-pollen palynomorphs and plant macrofossil remains was performed to reconstruct the paleoenvironmental history of the Cabeza de Buey shallow lake (36°17′S, 61°10′W) over the last 600 years. We identi

The Pampean region is a crucial area to obtain sensitive paleoclimatic lacustrine archives due to the presence of shallow environments in a territory non impacted by humans until the last centuries. In this study, we provide a paleoecological reconst

The Northern Hemisphere is currently warming at the rate which is unprecedented during the Holocene. Quantitative palaeoclimatic records show that the most recent time in the geological history with comparable warming rates was during the Pleistocene

Quaternary non-marine ostracods of Runtuyoc lake, northern Argentina: New taxonomic descriptions and the implication for Holocene paleoenvironment
Autor: Leandro David Rojo, D. Sabina D'Ambrosio, Sonia L. Fontana
Publikováno v: Journal of South American Earth Sciences. 98:102451
We performed an ostracod taxonomic analysis on samples from a shallow lake (Runtuyoc Lake) in north-western Argentina in order to contribute to the understanding of the evolution of this water body through the last 5000 years. The ostracod assemblage

A combined biogeochemical and palaeobotanical approach to study permafrost environments and past dynamics

Publikováno v: Journal of Quaternary Science. 30:189-200
When investigating past peatland processes and related carbon cycle dynamics, it is essential to identify and separate different peat environments: bogs, fens and permafrost, and their historical plant assemblages. Bog peat layers contain relatively
