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 ...

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.

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

open access: yesFrontiers 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.

Prompt rewetting of drained peatlands reduces climate warming despite methane emissions

open access: yesNature 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

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.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

open access: yesThe Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

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.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Updated chronologies for North American small mammal fossil localities in the Neotoma Paleoecology Database

open access: yesScientific Data
Community paleoecology is a powerful approach for analyzing ecological communities during long-term climate shifts like the Pleistocene-Holocene transition, but it depends on accurate estimates of species co-occurrences. The Neotoma Paleoecology Database
