The role of environmental factors in the conidiation of the predacious rotiferovorous fungus Zoophagus insidians (Zoopagomycota)
Compared to other groups of fungi, the knowledge of freshwater predacious fungi that feed on trapped rotifers and tardigrades is very limited. They are known to spread and survive under adverse conditions by releasing asexual spores (conidia), but the environmental factors that induce their conidiation are unclear. In this study, we investigated the conidiation of the rotiferovorous fungus Zoophagus insidians isolated from activated sludge and maintained under laboratory conditions in spring water (medium). We found that its conidiation can undergo significant changes in response to various environmental factors, such as medium exchange, presence or absence of prey, lighting conditions, and their combination. Our results revealed a surprisingly high flexibility of this obligate predacious fungus, which being constantly exposed to unpredictable availability of prey in an unstable environment is still able to survive and disperse.
期刊介绍:
Fungal Ecology publishes investigations into all aspects of fungal ecology, including the following (not exclusive): population dynamics; adaptation; evolution; role in ecosystem functioning, nutrient cycling, decomposition, carbon allocation; ecophysiology; intra- and inter-specific mycelial interactions, fungus-plant (pathogens, mycorrhizas, lichens, endophytes), fungus-invertebrate and fungus-microbe interaction; genomics and (evolutionary) genetics; conservation and biodiversity; remote sensing; bioremediation and biodegradation; quantitative and computational aspects - modelling, indicators, complexity, informatics. The usual prerequisites for publication will be originality, clarity, and significance as relevant to a better understanding of the ecology of fungi.
