A compilation of global bio-optical in situ data for ocean-colour satellite applications – version four

Abstract. A global in situ dataset for validation of satellite products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, with data starting in 1996, extends to 2025, which is important for the validation of recent algorit...

Sexual dimorphism of the human calcaneus: a cross-sectional morphometric study

Sex estimation from skeletal remains is a fundamental step in forensic anthropology. The calcaneus, the largest tarsal bone, is robust and may serve as an alternative indicator when the skull and pelvis are unavailable. This study evaluated sexual dimorphism in the calcaneus of a...

Magnetic fields and agro-industrial by-products as sustainable approaches to enhance carotenoid and lipid production by Rhodotorula mucilaginosa

This study aimed to evaluate magnetic fields (MF) and agro-industrial media as sustainable approaches to produce carotenoids and lipids by Rhodotorula mucilaginosa. Cultivations were carried out in shaken flasks with previously optimized agro-industrial media with sugarcane molas...

Common and rare stream diatoms respond differently to local, catchment and spatial drivers

Abstract The relative importance of environmental selection, dispersal, and demographic stochasticity in structuring aquatic communities remains poorly resolved, especially in human-impacted Neotropical regions. Using diatoms, we assessed how local environmental conditions, catch...

From living to fossil: parasitological evidence in modern and Pleistocene shells of Zidona dufresnii

Abstract Ecological live–live interactions in fossil invertebrates, although providing valuable information about the past environment and ecology, are still underexplored. Trematode parasites have a complex life cycle, often utilizing mollusks as their intermediate hosts. Howeve...
