Effects of
cryptogamic soil crust on the population dynamics of Arabis fecunda (Brassicaceae).
Physical properties of the psammophile
cryptogamic crust and their consequences to the water regime of sandy soils, north-western Negev Desert, Israel.
Unwittingly contradicting his long-standing argument for an all-encompassing approach, he observed that it had become impossible for one person to teach both vertebrate and invertebrate morphology, or to handle both phaenogamic and
cryptogamic botany.
Actylene reduction by
cryptogamic crusts from a blackbrush community as related to resaturation and dehydration.
Processes at this scale that impact soil erodibility and that are potentially impacted by changing environmental conditions include biological activity, both floral (such as vegetation cover or development of
cryptogamic crusts [Yair 1990; Chartres 1992]) and faunal (such as burrowing animals [Butler 1995]) and physical degradation (surface sealing, crusting, compaction).
Cryptogamic epiphytes may affect the chemistry of precipitation collected below a plant canopy (through-fall) by selective uptake or release of elements (Barkman 1958, Lang et al.
Consider the cyanobacterial crust (also known as
cryptogamic crust) that accounts for three-quarters of the living ground cover on the Colorado Plateau.
Although Moab's popularity among mountain bikers is a boon to the town's economy, it's a potential threat to the surrounding fragile desert environment (particularly to
cryptogamic soil, a black, mottled crust that holds soil in place and allows new plants to germinate).
Rather, they aim to protect tiny organisms that form a dark, knobby soil called
cryptogamic crust.
