Biparental care is a resilient evolutionarily strategy persisting across multiple species of small carpenter bees despite low paternity

Abstract Biparental care is rare in insects and is commonly attributed to genetic monogamy, which yields high fitness benefits for caring males. The discovery of biparental care despite low male paternity in the bee Ceratina nigrolabiata challenges this view. We tested whether th...

Extending the mineralogy of U 6+ (VII.): Kristekite, [Cu 2 (H 2 O) 4 (UO 2 )(SeO 3 ) 3 ]·4H 2 O, a new mineral from Příbram, Czech Republic.

The new mineral kristekite (IMA2025-101), [Cu 2 (H 2 O) 4 (UO 2 )(SeO 3 ) 3 ]•4H 2 O, was found in the dump material of the former uranium mine at Bytíz, near Příbram, Central Bohemia, Czech Republic, where it occurs as hedgehog-like aggregates, consisting of yellowish-green tabu...

Differing Patterns of Skeletal Disarticulation in Single and Multiple Burials

ABSTRACT This study presents a comparative taphonomic analysis of skeletal remains from a military cemetery in Prague‐Karlín (18th–19th century), focusing on joint disarticulation as a proxy for reconstructing postdepositional environments. The primary objective was to determine...
