On the formation of charred millet aggregates in archaeological assemblages

open access: yesArchaeometry, Volume 67, Issue 1, Page 202-218, February 2025.
Abstract Charred aggregates are one of the most common forms in which millets are preserved on archaeological sites. Despite the lack of consensus on their origin, few studies have attempted to determine how aggregates are formed. Knowing how aggregates are produced allows us to understand the diversity of processes operating in the formation of ...

Bigger genomes provide environment‐dependent growth benefits in grasses

open access: yesNew Phytologist, Volume 244, Issue 5, Page 2049-2061, December 2024.
Summary Increasing genome size (GS) has been associated with slower rates of DNA replication and greater cellular nitrogen (N) and phosphorus demands. Despite most plant species having small genomes, the existence of larger GS species suggests that such costs may be negligible or represent benefits under certain conditions.
