Facies Characterization and Volcanic Source Assignment of Marine Tephra Deposits Around São Miguel Island, Azores Archipelago

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Long‐term tephrostratigraphies of volcanic islands such as the Azores are often limited to young and incomplete subaerial records. Here, we present a Pleistocene‐Holocene marine tephra archive around the eastern islands of the Azores based on 22 marine gravity cores.

Dietary Phosphorus Requirement for Tambaqui, Colossoma macropomum, in the Grow‐Out Phase

Journal of Animal Physiology and Animal Nutrition, Volume 109, Issue 6, Page 1321-1332, November 2025.
ABSTRACT Phosphorus is essential for fish growth as it is crucial in skeletal development and metabolic reactions. The dietary requirement for this mineral varies among fish species and growth stages. Therefore, the objective of this study was to determine the available phosphorus (AP) requirement for tambaqui during the grow‐out phase (± 400 to 1000 g)
