Bacterial communities from three different sampling sites of a copper mine tunnel were characterized by 16S rRNA sequencing (NGS). A high presence halophilic bacteria was confirmed comparison with literature data and reference samples other highly salt-exposed soils. Among others, read numbers Gracilimonas, Kangiella, Limibacillus, Marinobacter, Woseia, uncultivated strains Actinomarinales, Gammaproteobacterium AT-s16, Actinobacteria 0319-7L14, Thiotrichaceae found. The community in sample the surface seam significantly composition floor. specificity appearance abundance special bacterial types (for example, Thiogranum, Thiohalophilus, Sulfuriflexus, Sedimenticolaceae, Desulfomonile, Desulfosporosinus, Cand. Thiobios) can be partially explained local conditions for sulfur-related metabolisms at sites.

Coral-associated microorganisms provide crucial nutritional, protective, and developmental benefits, yet many functional traits remain unexplored. Phototrophic bacteria may enhance coral nutrition reduce oxidative stress during bleaching via photosynthesis antioxidant production. Despite this potential, their role in the holobiont's energy budget heat resilience is understudied. This review explores potential of phototrophic to health under environmental stress.

Abstract Ocean warming will affect the functioning of coral reef ecosystems with unknown cascading effects. Any perturbation in ability sponges to recycle dissolved organic matter released by primary producers and make it available higher trophic levels, might have consequences for chain. Biogeochemical processes were measured sponge Rhabdastrella globostellata from semi‐enclosed lagoon Bouraké, where temperatures reach 33.8°C fluctuates 6.5°C on a daily basis, control (28°C). Using 13 C‐ 15 N‐labeled mucus, we experimentally investigated what extent high temperature affected carbon (C) nitrogen (N) resources allocation tissue detritus. Sponges Bouraké maintained at 32°C incorporated more mucus showed less detritus release when compared 28°C. In contrast, lower incorporation Our results suggest that adapted extreme able reallocate C N cell turnover somatic growth reduce damage. non‐adapted lack this mechanism underwent disintegration, highlighting lethal effect future warming. The change suggests potential adaptation allows R. survive under thermal stress, but could alter availability essential sources energy interactions.
