The objective of this study is to determine microhabitat preferences benthic species occurring in epilithic (living on stones), epipsammic (growing sand), epipelic mud) and epiphytic seagrass) assemblages the shallows Gulf Gdańsk (southern Baltic Sea). material was collected from 19 sites along Gdynia–Sopot coastal zone, including Port Gdynia. Most identified diatom taxa were observed two or th...

Cyanobacterial diversity from two geographical areas of Baja California Sur, Mexico, were studied: Bahia Concepcion, and Ensenada de Aripez. The sites included hypersaline ecosystems, sea bottom, hydrothermal springs, and a shrimp farm. In this report we describe four new morphotypes, two are marine epilithic from Bahia Concepcion, Dermocarpa sp. and Hyella sp. The third, Geitlerinema sp., occu...

The steady-state growth of a Flavobacterium strain known to utilize pentachlorophenol (PCP) was examined when cellobiose and PCP simultaneously limited its growth rate in continuous culture. A concentration of 600 mg of PCP per liter in influent medium could be continuously degraded without affecting steady-state growth. We measured specific rates of PCP carbon degradation as high as 0.15 +/- 0...

Biofilm communities are exposed to long periods of desiccation in temporary streams. We investigated how water flow intermittency affected the bacterial community structure colonizing three different streambed compartments in a Mediterranean stream. Massive parallel sequencing revealed different bacterial communities in biofilms from sand sediments and cobbles. Bacterial communities were simila...

A growing literature of deep but also surficial fossilized remains lithobiological life, often associated with igneous rocks, necessitates the unfolding a sub-discipline within paleobiology. Here, we introduce term paleolithobiology as new auxiliary under which lithobiology should be handled. We present key criteria that distinguish paleolithobiological archive from traditional one and discuss ...

As global climate change continues and the vegetation period lengthens, importance of research into cyanobacterial recruitment biomass associated toxin risks is growing. While most studies focus on planktonic cyanobacteria causing blooms, benthic have been less explored. This study reports for first time mass proliferation epilithic macrocolonies cyanobacteria, Gloeotrichia cf. natans, in water...
