Sedimentary Ancient DNA (sedaDNA) Reveals Fungal Diversity and Environmental Drivers of Community Changes throughout the Holocene in the Present Boreal Lake Lielais Svētiņu (Eastern Latvia)

Microorganisms, 2021
Fungi are ecologically important in several ecosystem processes, yet their community composition, ecophysiological roles, and responses to changing environmental factors in historical sediments are rarely studied. Here we explored ancient fungal DNA from

Biodiversidad, montañas y cambio climático

Collectanea 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 ...

The Paleoecology of Microplastic Contamination

Frontiers in Environmental Science, 2020
While the ubiquity and rising abundance of microplastic contamination is becoming increasingly well-known, there is very little empirical data for the scale of their historical inputs to the environment. For many pollutants, where long-term monitoring is

PALEOENVIRONMENTS RECONSTRUCTED FROM THE ANALYSES OF LOESS SEQUENCES ON SUSAK ISLAND, ADRIATIC SEA [PDF]

Acta Geographica Debrecina. Landscape & Environment Series, 2017
Susak Island is the outermost member of the archipelago of the Kvarner Bay, North Adriatic Sea, Croatia. Its long-term landscape evolution is defined by tectonic movements.

Paleoecología ecológica: Un eslabón perdido entre ecología y evolución

Collectanea 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.

The bivalve-bearing carbonate platform on the east Tethys during the middle Eocene and its response to the Tethys transgression

Frontiers in Earth Science
The Eocene was a typical greenhouse climate period in the history of the Earth, with a high global sea level and extensive carbonate deposits developed in Tethys.

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Prompt rewetting of drained peatlands reduces climate warming despite methane emissions

Nature Communications, 2020
Peatlands are strategic areas for climate change mitigation because of their matchless carbon stocks. Drained peatlands release this carbon to the atmosphere as carbon dioxide (CO2).

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

Frontiers 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.

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

Frontiers 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.
