Marine organisms in intertidal zones are subjected to periodical fluctuations and wave activities. To understand how microbes in intertidal biofilms adapt to the stresses, the microbial metagenomes of biofilms from intertidal and subtidal zones were compared. The genes responsible for resistance to metal ion and oxidative stresses were enriched in both 6-day and 12-day intertidal biofilms, incl...

Abstract. Mangrove forests are ecosystems that constitute a large portion of the world's coastline and span tidal zones below, between, above waterline, ecosystem as whole is defined by health these microhabitats. However, we only beginning to understand tidal-zone microbial biodiversity role microbiomes in nutrient cycling. While extensive research has characterized pristine vs. anthropogenica...

The presence of large carnivores can affect lower trophic levels by suppressing mesocarnivores and reducing their impacts on prey. The mesopredator release hypothesis therefore predicts prey abundance will be higher where large carnivores are present, but this prediction assumes limited dietary overlap between large and mesocarnivores. Where dietary overlap is high, e.g., among omnivorous carni...

This study proposes a standardization process for monitoring the level of tar mat contamination in Arabian Gulf. In study, we selected target gastropod species and evaluated ecological ecotoxicological effects mats on their populations, bioaccumulation heavy metals, these species’ potential as bioindicator taxa mat-associated metals. The was carried out at two sites Qatar coast shoreline rocks,...

Intertidal macroalgae are regularly exposed to hypo- or hypersaline conditions which stressful. However, red algae in New Zealand generally poorly studied terms of salinity tolerance. Consequently, two native (Bostrychia arbuscula W. H. Harvey [Ceramiales], Champia novae-zelandiae [J. D. Hooker & Harvey] [Rhodymeniales]) and one introduced algal taxon (Schizymenia spp. J. Agardh [Nemastomatales...
