EXPERIMENTAL TAPHONOMY OF FRESHWATER DIATOMS: DISCRIMINATING BETWEEN CHEMICAL AND PHYSICAL CAUSES OF FRUSTULE FRAGMENTATION

Autor: GABRIELA S. HASSAN, MARISEL C. DIAZ

Publikováno v: Palaios. 38:125-135

Frustule fragmentation is one of the major taphonomic factors affecting diatom preservation in Pampean shallow lakes. Although this has been demonstrated by taphonomic studies conducted on extant and fossil material, little is known about the causes

Premortem and postmortem processes significantly influence the formation of the molluscan fossil record in freshwater environments. Despite their importance for paleoenvironmental studies, they remain poorly understood. In Pampean shallow lakes, Holo

IAL-IPA 2022 Abstract Book - Lagos Memorias del Territorio

Autor: Gabriela S. Hassan, M. Eugenia de Porras, Silvana R. Halac, Francisco E. Córdoba

The goal of the IAL IPA 2022 joint meeting is to celebrate research on lakes from multiple perspectives with a focus on the sediment record as both an Earth System archive and a social and cultural memory of the territory. This conference aims to bri

Within versus between-lake variability of sedimentary diatoms: the role of sampling effort in capturing assemblage composition in environmentally heterogeneous shallow lakes

Autor: Gabriela S. Hassan

Publikováno v: Journal of Paleolimnology. 60:525-541

The effect ofwithin-lake diatom assemblages variability on sample representativity and itssubsequent impact on between-lake comparisons were addressed in threeenvironmentally heterogeneous shallow lakes from the Argentinean Pampas.Surface sediment sa

Distribution of epiphytic diatoms on five macrophytes from a Pampean shallow lake: host-specificity and implications for paleoenvironmental reconstructions

Autor: Gabriela S. Hassan, Luciana A. Rojas

Publikováno v: Diatom Research. 32:263-275

Epiphytic diatoms are an important component of death and fossil assemblages in macrophyte-dominated shallow lakes. In the Argentinean Pampas, the lack of studies on the composition, diversity and distribution of epiphytic diatoms limits the extent o

Evaluación de la influencia de los ambientes salinos y alcalinos en la preservación de las diatomeas pampeanas: Un enfoque experimental

Autor: Gabriela S. Hassan, Marisel C. Diaz

Diatom dissolution is controlled by environmental conditions prevailing during fossilization. In Pampean shallow lakes, diatom dissolution showed important correlations with gradients of salinity, pH, carbonate, and bicarbonate, being these the most

Actualistic Taphonomy of Freshwater Mollusks from the Argentine Pampas: An Overview of Recent Research Progress

Autor: Eleonor Tietze, Paula Andrea Cristini, Claudio G. De Francesco, Gabriela S. Hassan

Publikováno v: Topics in Geobiology ISBN: 9783030206246

Historically, the development of taphonomic studies in freshwater environments has been scarce and mainly restricted to the Northern Hemisphere, with almost no information on how taphonomic processes work (and eventually differ) in the Southern Hemis
