Primary succession often involves colonization of microscopic heterotrophs before autotrophs.
The heaps of oil shale mining wastes consist of pure substrate open to primary succession and constitute possible habitats for soil invertebrates.
Change is caused directly by alterations in glacial mass balance, which is mediated through reduced ice cover, an initial increase in stream discharge, and the release of land for primary succession. There are also increases further away from the direct influences of the glaciers in the abundance of woody plants, perhaps due at least in part to higher carbon dioxide levels in the atmosphere.

Primary succession in ponds results from the slow filling of the body of water with silt and organic debris until plants can gradually invade from the banks toward the middle.
In conclusion, the grasshopper species in the primary succession studied here appear to have adopted two opposite strategies, both conditioned by a greater size of the females over the males.
(2001) reported that nficrobial community composition changed with primary succession from shore to inland forest.
The role of life history processes in primary succession on an Alaskan floodplain.
Connell and Slatyer concluded that facilitation may be important in severe environments, as often occurs during early primary succession, that there is little evidence for the tolerance model, and that most successional changes are best explained by the inhibition model, because late-successional species g row better when initial colonizers are removed.
Soil chronosequences of different-aged geologic substrates are valuable tools for investigating slow processes such as primary succession and forest ecosystem development.
Development of vegetation in levelled quarry spoil follows primary succession. In another site, quarry spoil has been covered with previously removed soil offering more favourable conditions for vegetation development.
While there are considerable data on primary succession in boreal flood plains and tundra environments (e.g., Viereck, 1970; Lambert, 1972; Gill, 1973; Billings and Peterson, 1980; Ovenden, 1986), less is known about sequences developed on disturbances in the ice-rich terrain of the boreal forest.
