Unravelling Hypoxia Tolerance: Transcriptomic and Metabolic Insights From Lucinoma capensis in an Oxygen Minimum Zone

open access: yesMolecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT The lucinid clam Lucinoma capensis thrives at the oxygen minimum zone margins in the Benguela Upwelling System, where oxygen levels fluctuate dramatically. Understanding its adaptation to such extreme conditions provides key insights into survival strategies under fluctuating oxygen availability.

Legacy effects of inundation on greenhouse gas emissions and soil dynamics in forage systems

open access: yesAgronomy Journal, Volume 117, Issue 6, November/December 2025.
Abstract Soil inundation increases anaerobiosis, slows organic matter decomposition, and affects greenhouse gas production from soils. The objective of this study was to evaluate the effects of natural short‐duration recurring inundation on CO2, CH4, and N2O emissions, as well as on labile soil permanganate oxidizable carbon and autoclaved‐citrate ...

Characterization of novel beta-galactosidase activity that contributes to glycoprotein degradation and virulence in Streptococcus pneumoniae.

open access: yes, 2009
The pneumococcus obtains its energy from the metabolism of host glycosides. Therefore, efficient degradation of host glycoproteins is integral to pneumococcal virulence.
