Cryptoendolith alteration of Antarctic sandstone substrates: pioneers or opportunists?
Introduction: Lichen dominated cryptoendolithic communities from the Dry Valleys of Antarctica have been the subject of much research over recent years owing to their potential as analogues of Martian lifeforms. This is primarily owing to the stress tolerant nature of the microorganisms, remarkable adaptive achievements and the similarities between the Antarctic Dry Valley ecosystems and condit...
متن کاملAcid microenvironments in microbial biofilms of antarctic endolithic microecosystems.
Antarctic endolithic microecosystems harbour distinct biofilms. The lithic substrate and the microorganisms comprising these films are intimately linked, leading to complex mineral-microbe interactions. Hence, the microhabitats and microenvironments of these microecosystems are not only determined by the physicochemical features of the lithic substrate, but are also conditioned by the biologica...
متن کاملThe effect of low temperature on Antarctic endolithic green algae.
Laboratory experiments show that undercooling to about -5 degrees C occurs in colonized Beacon sandstones of the Ross Desert, Antarctica. High-frequency temperature oscillations between 5 degrees C and -5 degrees C or -10 degrees C (which occur in nature on the rock surface) did not damage Hemichloris antarctica. In a cryomicroscope, H. antarctica appeared to be undamaged after slow or rapid ...
متن کاملPolar endoliths – an anti-correlation of climatic extremes and microbial biodiversity
We examined the environmental stresses experienced by cyanobacteria living in endolithic gneissic habitats in the Haughton impact structure, Devon Island, Canadian High Arctic (75x N) and compared them with the endolithic habitat at the opposite latitude in the Dry Valleys of Antarctica (76x S). In the Arctic during the summer, there is a period for growth of approximately 2.5 months when tempe...
متن کاملCryptoendolith communities in Antarctic dry valley region sandstones: Potential analogues of Martian life-forms
Introduction: Cryptoendolithic communities colonizing sandstones in the Dry Valleys of Antarctica have been the subject of much research over recent years, owing to their potential as analogues of Martian life-forms. Interest in them stems from the similarities between the Antarctic cold desert ecosystems, representing some of the most extreme of terrestrial environmental habitats, and the cond...
