Biotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms.
Surface colonization and subsequent biofilm formation and development provide numerous …

Dysoxic marine waters (DMW,< 1 μM oxygen) are currently expanding in volume in the
oceans, which has biogeochemical, ecological and societal consequences on a global …

Microbially-driven sulfur cycling is a vital biogeochemical process in the sulfur-rich
mangrove ecosystem. It is critical to evaluate the potential impact of sulfur transformation in …

Background The sulfur cycle encompasses a series of complex aerobic and anaerobic
transformations of S-containing molecules and plays a fundamental role in cellular and …

Although regime shifts are known from various ecosystems, the involvement of microbial
communities is poorly understood. Here we show that gradual environmental changes …

Polysulfides (Sx2−) are sulfide oxidation intermediates that are important for a variety of
environmentally relevant processes including pyrite formation, organic matter sulfidization …

Although bacteria play key roles in aquatic food webs and biogeochemical cycles,
information on the seasonal succession of bacterial communities in lakes is still far from …

Abstract Rogoznica Lake (RL;“Zmajevo oko”) is a shallow marine body of water that exhibits
the physical characteristics of lakes (layer overturn and morphology), estuaries (distinct …

In Croatia, a variety of geothermal springs with a wide temperature range and varied
hydrochemical conditions exist, and they may harbor different niches for the distribution of …

Hydrothermal plumes transport reduced chemical species and metals into the open ocean.
Despite their considerable spatial scale and impact on biogeochemical cycles, niche …
