The microbiota is an important component of the epilithic algal matrix (EAM) and plays a central role in biogeochemical cycling nutrients coral reef ecosystems. Insufficient studies on EAM diversity have led to limited understanding ecological functions EAMs different states. To explore microbial community Luhuitou fringing Sanya, China, which has undergone incessant expansion domination algae ...

A variety of syn-vivo bioerosion traces produced by foraminiferans is recorded in shells of Nautilus sampled near New Caledonia and Vanuatu. These are two types of attachment scars of epilithic foraminiferans and two forms of previously undescribed microborings, a spiral-shaped and a dendritic one, both most likely being the work of endolithic 'naked' foraminiferans. Scanning electron microscop...

A sandstone outcrop exposed to freshwater seepage supports a diverse assemblage of photosynthetic microbes. Dominant taxa are two cyanophytes (Oscillatoria sp., Rivularia sp.) and a unicellular green alga (Palmellococcus sp.). Less abundant taxa include a filamentous green alga, Microspora, and the desmid Cosmarium. Biologic activity is evidenced by measured levels of chlorophyll and lipids. Bi...

Abstract Identifying and quantifying nitrogen pools is essential for understanding the cycle in aquatic ecosystems. The ubiquitous diatoms represent an overlooked nitrate pool as they can accumulate intracellularly utilize it assimilation, dissipation of excess photosynthetic energy, Dissimilatory Nitrate Reduction to Ammonium (DNRA). Here, we document global co-occurrence intracellular phototr...

Diatoms have traditionally been used to assess water quality; however, current research suggests that physical factors, such as habitat and landscape, may be linked the organization of diatom assemblages in streams. The aim this study was determine environmental factors affecting physiological ecological changes epilithic diatoms. To end, dominant species were used, a strategy based on characte...
