Mercury Content and Pools in Complex Polycyclic Soils From a Mountainous Area in Galicia (NW Iberian Peninsula)

Autor: Antía Gómez-Armesto, Melissa Méndez-López, Andrea Parente-Sendín, Noemi Calvo-Portela, Xabier Pontevedra-Pombal, Eduardo García-Rodeja, Flora Alonso-Vega, Juan Carlos Nóvoa-Muñoz

Publikováno v: Spanish Journal of Soil Science, Vol 13 (2023)

Atmospheric mercury (Hg) usually tends to accumulate in the upper horizons of soils. However, the physico-chemical characteristics of some soils, as well as pedogenetic processes, past climate changes, or soil degradation processes, can lead to a red

Distribution of testate amoebae in bryophyte communities in São Miguel Island (Azores Archipelago)

Autor: Martin Souto, Vítor Gonçalves, Xabier Pontevedra-Pombal, Pedro Raposeiro

Publikováno v: Biodiversity Data Journal, Vol 9, Iss , Pp 1-23 (2021)

Testate amoebae are a polyphyletic group of protists living preferentially in soils, freshwaters and wetlands. These Protozoa have worldwide distribution, but their presence and diversity in the Azores (a remote oceanic archipelago) is poorly known,

Diversity of Testate Amoebae as an Indicator of the Conservation Status of Peatlands in Southwest Europe

Autor: Rafael Carballeira, Xabier Pontevedra-Pombal

Publikováno v: Diversity, Vol 13, Iss 6, p 269 (2021)

Testate amoebae are one of the most studied groups of microorganisms in Sphagnum peatland ecosystems and, therefore, one of the most reliable bioindicators of their ecological status. Peatland ecosystems are supported by a delicate biogeochemical bal

Diatoms in Paleoenvironmental Studies of Peatlands

Autor: Rafael Carballeira, Xabier Pontevedra-Pombal

Publikováno v: Quaternary, Vol 3, Iss 2, p 10 (2020)

The great diversity of diatoms in aquatic ecosystems and their close relationship with water chemistry make them one of the most informative and widely used biological proxies in paleoenvironmental studies of wetlands, except for peatland ecosystems.

POSTGLACIAL VEGETATION AND CLIMATE CHANGES INFERRED FROM A PEAT POLLEN RECORD IN THE RÍO PIPO VALLEY, SOUTHERN TIERRA DEL FUEGO

Autor: Ana M. Borromei, Lorena L. Musotto, Andrea Coronato, Juan F. Ponce, Xabier Pontevedra-Pombal

Publikováno v: Publicación Electrónica de la Asociación Paleontológica Argentina, Vol 16, Iss 2 (2016)

Abstract. The pollen analysis from Cañadón del Toro peat bog (54° 49’ 36” S; 68° 27’ 36” W), located in an interior valley of the Fuegian Andes, provides information about vegetation and climate changes during the last 13,500 years. The r

The Use of Plant Macrofossils for Paleoenvironmental Reconstructions in Southern European Peatlands

Autor: Martin Souto, Daniel Castro, Eduardo García-Rodeja, Xabier Pontevedra-Pombal

Publikováno v: Quaternary, Vol 2, Iss 4, p 34 (2019)

The analysis of plant macrofossils in peatland ecosystems has been widely used for the climatic and ecological reconstruction of the Holocene in the high latitudes of the northern hemisphere. By contrast, perhaps associated with rarity of these ecosy

Inestabilidad de ladera natural e inducida asociada a grandes movimientos en masa durante el Pleistoceno-Holoceno en la Serra dos Ancares (NW de la Península Ibérica)

Autor: Marcos Valcarcel, Alexandre Luis Vázquez-Rodríguez, Xabier Pontevedra-Pombal

Publikováno v: Anales de Geografía de la Universidad Complutense. 42:301-329

La Serra dos Ancares es un espacio natural afectado por los procesos glaciales del Cuaternario, y que presenta fuertes pendientes en sus laderas. Se describen hasta 28 movimientos de masas en todo el sector estudiado. Los deslizamientos existentes se
