Oxygen consumption from air and water, ammonia and urea‐N excretion, and Na+ fluxes during progressive aquatic hypoxia in Amazonian armoured catfish Pterygoplichthys gibbiceps and Pterygoplichthys pardalis

open access: yesJournal of Fish Biology, EarlyView.
Abstract The Amazonian loricariid fish Pterygoplichthys gibbiceps, from the Rio Negro, and Pterygoplichthys pardalis, from the Rio Solimões, are facultative air‐breathers that can use the stomach as an air‐breathing organ. Measurement of oxygen uptake under progressive aquatic hypoxia revealed a relatively high hypoxia resistance of both species.

Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon

open access: yesJournal of Fish Biology, EarlyView.
Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

The tympanic covering layer contributes to basilar membrane elasticity potentially influencing human frequency resolution and speech perception

open access: yesJournal of Anatomy, EarlyView.
In this study we show for the first time that the human basilar membrane contains elastin produced by the so‐called tympanic covering layer. It is believed to play an important functional role in human cochlear tuning, particularly low frequencies linked to our remarkable speech and music perception.

Between Financial and Socioemotional Wealth: Navigating Knotted Tensions in Family Business Innovation

open access: yesJournal of Product Innovation Management, EarlyView.
ABSTRACT Current research on family business innovation tends to isolate individual tensions for analysis, while in reality, these tensions often arise in complex entanglements. To fill this research void, we focus on understanding how multiple tensions occur in the innovation process, how these tensions are entangled, and how they are managed. We turn

Why Industrial Internet of Things Platforms Fail: A Structuration Theory Perspective on Platform Evolution

open access: yesJournal of Product Innovation Management, EarlyView.
ABSTRACT Despite their transformative potential, Industrial Internet of Things (IIoT) platforms often fail to evolve into scalable ecosystems. Research on IIoT platforms attributes failure to discrete factors such as governance misalignment or technological complexity and rarely considers how failure unfolds.
