Experimental observations and field data demonstrated that predators adapt their hunting strategies in response to prey abundance. While previous studies explored the impact of predation risk on predator-prey interactions, the impact of symbiotic relationships between fear-affected prey and non-prey species on system dynamics remains unexplored. This study uses a mathematical approach to investigate how different symbiotic relationships govern system dynamics when predators adapt to prey availability. Our study illustrates that the mutualistic relationship between prey and partners extends predator survivability. However, the fear-affected symbiotic system may undergo regime shifts, which can be catastrophic or non-catastrophic, depending on symbiotic interaction patterns. The study demonstrates a hump-shaped relationship between the predator's optimal search rate and biomass and identifies an intermediate range of search rates where the system exhibits a "bubbling"phenomenon. Overall, our findings provide new insights into symbiotic relationships in community ecology, highlighting the complex interplay among predators, prey, and non-prey species.

Chlorpyrifos (CPF), a widely used organophosphate insecticide in cotton cultivation for controlling Aphis gossypii, has Binodoxys communis as the primary parasitic natural enemy of A. gossypii. This study evaluated the impact of two sub-lethal CPF concentrations (LC10 and LC30) on key biological parameters across two generations, transcriptomic responses, and symbiotic bacterial communities in B.

Lichens exemplify a unique symbiotic relationship between fungi and algae or cyanobacteria, where fungi (mycobionts) provide structural support, while algae or cyanobacteria (photobionts) provide nutrients. Recent discoveries in the order Chaetothyriales have led to the description of several lichenicolous species, underscoring an intricate relationship of some black yeast-like fungi with lichens. The present study aims to investigate public metagenomic data of lichens available in the SRA database, covering a total of 2888 samples.

This study explores the role of α-Fe₂O₃ in improving extracellular electron transfer (EET) and symbiotic interactions between electroactive Shewanella oneidensis MR-1, its gene-deficient mutants (ΔmtrC, ΔomcA, and ΔcymA), and microalgae (Chlorella vulgaris). The iron oxide facilitates the efficient transfer of electrons generated by MR-1 to microalgal photosystem via the pathway of CymA-MtrC-OmcA to α-Fe₂O₃. This process enhances the removals of TOC, TN, and NH₄⁺-N in the MR-1 bacterial-algal consortium by 9.

Legumes form symbioses with nitrogen-fixing bacteria, well studied metabolically but less so in terms of respiration. Symbiotic nitrogen fixation demands high respiratory ATP and carbon skeletons, linking nitrogen assimilation and both NADH- and ATP-dependent process to mitochondrial respiration. The plant mitochondrial electron transport chain contains two terminal oxidases that differentially fractionate against O, providing estimations in vivo of the energy efficiency of respiration.

Boat noise has been shown to distract and cause harm to many marine organisms. Most of the study effort has focused on fish & marine mammals, even though invertebrates represent over 92 % of all marine life. The few studies conducted on invertebrates have demonstrated clear negative effects of anthropogenic noise pollution.
