Late Miocene to early Pliocene biofacies of Wanganui and Taranaki Basins, New Zealand: Applications to paleoenvironmental and sequence stratigraphic analysis [PDF]

open access: yes, 2004
The Matemateaonga Formation is late Miocene to early Pliocene (upper Tongaporutuan to lower Opoitian New Zealand Stages) in age. The formation comprises chiefly shellbeds, siliciclastic sandstone, and siltstone units and to a lesser extent non-marine and

The maturing relationship between Quaternary paleoecology and ancient sedimentary DNA

open access: yesQuaternary Research, 2020
In the two decades or so since ancient sedimentary DNA (sedaDNA) took its place as a new Quaternary paleo-proxy, there have been large advances in the scope of its applications and its reliability.

Biodiversidad, montañas y cambio climático

open access: yesCollectanea Botanica, 2014
En este artículo se discute el origen y mantenimiento de la biodiversidad en las montañas tropicales, con énfasis en el Neotrópico, y se concluye que los patrones de biodiversidad de las biotas de gran altura no pueden ser explicados sin la acción ...

MetaDamage tool: Examining post-mortem damage in sedaDNA on a metagenomic scale

open access: yesFrontiers in Ecology and Evolution, 2023
The use of metagenomic datasets to support ancient sedimentary DNA (sedaDNA) for paleoecological reconstruction has been demonstrated to be a powerful tool to understand multi-organism responses to climatic shifts and events.

Paleoecología ecológica: Un eslabón perdido entre ecología y evolución

open access: yesCollectanea Botanica, 2014
La paleoecología es más que una disciplina ambiental, ya que proporciona las evidencias empíricas necesarias para verificar hipótesis ecológicas y contribuye a una mejor comprensión de la interfase ecología-evolución.

87Sr/86Sr in Archeological and Paleobiological Research: A Perspective

open access: yesFrontiers in Ecology and Evolution, 2021
The stable isotope ratio 87Sr/86Sr has been shown to have extraordinary potential for documenting the movement and life-histories of humans and other animals, both in history and prehistory.

What Happens Between Depositional Events, Stays Between Depositional Events: The Significance of Organic Mat Surfaces in the Capture of Ediacara Communities and the Sedimentary Rocks That Preserve Them

open access: yesFrontiers in Earth Science, 2022
In the absence of complex, bioturbating organisms, the seafloor during the Precambrian was covered in widespread organic matgrounds. The greatest diversity and complexity of organic mat textures occur in the Ediacaran fossil record as exemplified by the ...
