A Geostratigraphic Map of the Rachmaninoff Basin Area: Integrating Morphostratigraphic and Spectral Units on Mercury

open access: yesEarth and Space Science
Geological maps of Earth typically incorporate field observations of rock lithology, structure, composition, and more. In contrast, conventional planetary geological maps are often made using primarily qualitative morphostratigraphic remote sensing ...

Using Environmental DNA Sampling for Simultaneous Detection of Hosts and Their Pathogens: A Case Study With the Critically Endangered Frog Genus Atelopus

open access: yesAnimal Conservation, EarlyView.
Environmental DNA is a powerful tool for simultaneous detection of rare species and their pathogens. We confirmed the presence of Atelopus at multiple sampling locations and found that the concentration of the amphibian pathogen Bd in eDNA samples was correlated with stream characteristics and the pathogen load of the amphibian community.

What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

open access: yesArchaeometry, EarlyView.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

Levantine Hacksilber and the flow of silver in early Mediterranean commerce

open access: yesArchaeometry, EarlyView.
Abstract This study presents a comprehensive approach to provenancing ancient silver artefacts, introducing a novel algorithm to correct for mass‐dependent isotope fractionation. Applied to a Pb isotope database of 281 Hacksilber samples from southern Levantine hoards (1700–600 BCE) and compared with approximately 7000 galena ores from Spain to Iran ...

Climate change sensing across work and home: A research diary experiment

open access: yesArea, EarlyView.
Abstract As we contend with climate change, understanding its impacts on our everyday lives and work becomes increasingly crucial. In this paper, we applied research diaries as an innovative qualitative method to better understand how we, a team of climate change researchers in Melbourne (Australia), experience, sense, and make sense of and adapt to ...
