ABSTRACT Aeolian desertification poses a critical threat to ecosystem stability in arid regions worldwide. Although the combination of sand barriers and vegetation has been widely applied for sand fixation, its long‐term effectiveness is constrained by barrier degradation, slow natural development of biological soil crusts (BSCs), and the resulting ...

The lichen flora of the Chagos Archipelago : including a comparison with other island and coastal tropical floras [PDF]
The 1996 Chagos Expedition provided the first opportunity to study the archipelago’s lichen flora. Seventeen of the 55 islands were ecologically investigated, some in more detail than others, and lists and representative collections of lichens have been ...

ABSTRACT Biological soil crusts (biocrusts) are crucial components of dryland ecosystems; however, they are highly vulnerable to anthropogenic disturbances, particularly trampling caused by grazing. To evaluate the impacts of trampling on biocrust structure, microbial communities, and soil functions, we conducted a mesocosm‐based simulated disturbance ...

ABSTRACT Establishing biocrusts on sandy surfaces in harsh desert environments presents significant challenges due to extreme ecological conditions. To address these challenges, this study examined the effects of two organic superabsorbent cellulosic polymers (OSCPs)—carboxymethyl cellulose (CMC) and guar gum (GUA)—on the establishment of ...

Lichens and eutrophication [PDF]
Eutrophication is a process of organic nutrients enrichment in an ecosystem, especially nitrogen and phosphorus. This bachelor thesis is dealing with the influence of eutrophication on lichens, especially with the effect of nitrogen compounds in the air ...
