Late Pleistocene–Holocene environmental fluctuations of southern Chihuahua Desert, Mexico

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Paleoenvironmental reconstructions from the Mexican Chihuahua Desert based on biological proxies are scarce, creating a gap in our understanding of the ecological responses to climate change in this water‐scarce region. Here, we present a paleoenvironmental reconstruction based on geochemical data and biological proxies such as ostracods and ...

Sedimentary ancient DNA from caves: Challenges and opportunities

open access: yesJournal of Quaternary Science, EarlyView.
Abstract Caves are unique depositional environments that hold great potential for long‐term preservation of DNA due to their typically cool and stable internal climates, buffered from external climate extremes. Bones from caves have long been recognised as an excellent source of ancient DNA, yet the potential for DNA preservation in cave sediments ...

Application of 3D Raman Mapping on Complex Inclusions: A Case Study of the Styrian Basin Mantle Xenoliths (W‐Carpathian Pannonian Region)

open access: yesJournal of Raman Spectroscopy, EarlyView.
Recent advancements in spectral and spatial resolutions for Raman spectroscopy allow the analysis of fluid and melt inclusions. To explore the applicability of 3D Raman mapping, we conducted 3D Raman mapping on inclusions hosted by orthopyroxene in modally metasomatized mantle xenoliths from the Styrian Basin (W‐Carpathian Pannonian Region).

Dynamics of surface accretion and surface elevation differ between river and tide dominated settings in tropical mangroves

open access: yesLimnology and Oceanography, EarlyView.
Abstract The maintenance of soil surface elevation in mangroves supports the persistence of mangroves with sea level rise. The processes contributing to soil surface elevation have rarely been assessed in the humid tropics, despite most mangroves occurring in river deltas and tidal estuaries within this climate zone. Using surface elevation table (SET)
