Improving average ranking precision in user searches for biomedical research datasets

open access: yes, 2017
Availability of research datasets is keystone for health and life science study reproducibility and scientific progress. Due to the heterogeneity and complexity of these data, a main challenge to be overcome by research data management systems is to ...

Y-chromosome phylogeographic analysis of the Greek-Cypriot population reveals elements consistent with Neolithic and Bronze Age settlements [PDF]

open access: yes, 2015
International audienceBackground: The archeological record indicates that the permanent settlement of Cyprus began with pioneering agriculturalists circa 11,000 years before present, (ca. 11,000 y BP).

Ostracod Genetic Variability in Response to Lake Level‐Driven Salinity Dynamics in Nam Co, Central Tibetan Plateau, in the Past Two Millennia

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Using sedimentary ancient DNA metabarcoding on a two‐millennia sediment core from Nam Co (Tibetan Plateau), the study reconstructs ostracod community shifts and genetic diversity in response to hydrological and climatic changes. Species richness peaked during moister intervals, while alternating dominance during the Medieval Climate Anomaly and Little ...

Los antepasados del oso de las Cavernas [PDF]

open access: yes, 2001
[Abstract] The lineage of the cave bear Ursus deningeri--> U. Spelaeus is well known, but to draw a limit in this evolution is not easy. The real difficulty is met when this cave bear lineage has to be linked to its ancestors...

Making vertebrate fossil radiocarbon dates more useful for global scientific research

open access: yesJournal of Quaternary Science, Volume 40, Issue 8, Page 1309-1335, November 2025.
ABSTRACT Radiocarbon dating of bones is essential for reconstructing timelines of species' occurrences, domestication, extinction, migrations, and interactions with Quaternary environments. Many studies compile these chronologies at continental to global scales by aggregating radiocarbon dates from various sources, often balancing data quantity and ...

Carriers of human mitochondrial DNA macrohaplogroup M colonized India from southeastern Asia [PDF]

open access: yes, 2016
Background: From a mtDNA dominant perspective, the exit from Africa of modern humans to colonize Eurasia occurred once, around 60 kya, following a southern coastal route across Arabia and India to reach Australia short after.

Introducing FAMM: An Open‐Access Database of Fossil Arctic Marine Mammals

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 9, September 2025.
ABSTRACT Motivation The Arctic is currently experiencing the strongest effects of climate change on Earth. These effects, including sea ice loss, are already modifying the ecologies of the 11 species of marine mammals found in the Arctic year‐round.

Investigating Development in Human Evolution: Specificities, Challenges, and Opportunities

open access: yesEvolutionary Anthropology: Issues, News, and Reviews, Volume 34, Issue 1, March 2025.
ABSTRACT Unlike developmental biologists, paleoanthropologists primarily investigate development using skeletal remains, specifically fossilized and already‐formed bones and teeth. Focusing on peri‐ and/or postnatal growth, they reconstruct development from fragmented “snapshots” of individual trajectories at various ontogenetic stages.

RRphylogeography: A new method to find the area of origin of species and the history of past contacts between species

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 3, Page 546-557, March 2025.
Abstract One of the main goals of historical biogeography is understanding where species originated, and how climate change and ecological interactions shaped their distribution. The task is complicated by both active and passive mechanisms, including habitat tracking, the separation of species into metapopulations of variably interconnected demes, and
