Our results have significant implications for temporal studies that use tracers, especially when consumers have the potential to change diets. Variations in the metabolic turnover rates of stable isotope ratios and fatty acids in the muscle tissues of the shrimp were largely driven by the quality of the food provided and revealed physiological flexibility in an omnivorous consumer.]]> Tue 08 Apr 2025 14:25:46 SAST ]]> Detection of plant growth enhancing features in psychrotolerant yeasts from Patagonia (Argentina) https://commons.ru.ac.za/vital/access/manager/Repository/vital:74744 Tue 06 Aug 2024 16:20:43 SAST ]]> Ericoid fungal inoculation of blueberry under commercial production in South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:74746 0.05) shoot growth and biomass.
