THE ECOLOGY OF NOSTOC

Nostoc is a genus of filamentous cyanobacteria that can form macroscopic or microscopic colonies and is common in both terrestrial and aquatic habitats. Much of the success of Nostoc in terrestrial habitats is related to its ability to remain desiccated for months or years and fully recover metabolic activity within hours to days after re‐hydration with liquid water. Nostoc can also withstand repeated cycles of freezing and thawing and, thus, is an important component of extreme terrestrial…

The objective of this review is to evaluate the mechanisms behind the low rates of growth and mortality, protection against environmental hazards and the persistence and longevity of gelatinous Nostoc colonies, and their ability to economize with highly limiting resources.

Cyanobacteria colonize the soil surface in deserts where they coexist with other organisms such as mosses, lichens, bacteria, fungi, archaea, and microalgae, in communities known as biocrusts.…
Macroscopic cyanobacteria of the genus Nostoc: a neglected and endangered constituent of European inland aquatic biodiversity

Life conditions for these species in Europe in the ‘virgin’ postglacial biosphere, historical reports and the present-day situation are surveyed and the classic descriptions and diagnoses based only on herbarium material are supplemented by ontogenetic details.
Dinitrogen fixation by biological soil crusts in an Inner Mongolian steppe
- Environmental ScienceBiology and Fertility of Soils
- 2009
It is demonstrated that N2 fixation by Nostoc can potentially replace significant amounts, if not all, of the nitrogen lost in the form of N2O and NO soil emissions in this steppe ecosystem.
Growth of cyanobacterial soil crusts during diurnal freeze-thaw cycles
- Environmental ScienceJournal of Microbiology

Results show that freeze-thaw cycles alone do not limit the growth of BSCs in high-elevation soils, and provide new insight into how life is able to thrive in one of the most extreme terrestrial environments on Earth.

This chapter outlines the major constraints on cyanobacteria in these environments and suggests that top-down control via grazing may also help to explain diverse patterns of cyanobacterial abundance.

Nitrogen fixation as measured by acetylene conversion to ethylene was found to be common for duckweed blooms on ponds, lakes, and streams in Michigan and correlated reasonably well with the density of cyanobacterial colonies observed.

Effects of Macroalgae on a Stream Invertebrate Community

The presence of macroalgae was associated with greater total densities and taxon richness of invertebrates, and nearly all taxa responded significantly to algal removal on at least some dates, and natural disturbances will indirectly affect invertebrate distributions and abundances by affecting the distributions and abundance of Macroalgae.
