Plant life at the dry limit-Spatial patterns of floristic diversity and composition around the hyperarid core of the Atacama Desert.

open access: yesPLoS ONE, 2020
Extreme arid conditions in the Atacama Desert in northern Chile have created a unique vegetation almost entirely restricted to the desert margins along the coast of the Pacific Ocean and the Andean range.

Transitivity of the climate–vegetation system in a warm climate [PDF]

open access: yesClimate of the Past, 2015
To date, the transitivity of the global system has been analysed for late Quaternary (glacial, interglacial, and present-day) climate. Here, we extend this analysis to a warm, almost ice-free climate with a different configuration of continents.

Species composition and abundance of solpugids (Arachnida: Solifugae) in ecotopes of the transitional coastal desert of Chile

open access: yesRevista Mexicana de Biodiversidad, 2011
Using pitfall traps, the species composition and abundance of solpugids were studied in several ecotopes of Chile’s transitional coastal desert. The study was conducted in the area around Punta de Choros (29º15’S, 71º26’W) and in Los Choros Archipelago ...

Biodiversity of ecosystems in an arid setting: The late Albian plant communities and associated biota from eastern Iberia.

open access: yesPLoS ONE, 2023
Deserts are stressful environments where the living beings must acquire different strategies to survive due to the water stress conditions. From the late Albian to the early Cenomanian, the northern and eastern parts of Iberia were the location of the ...

Ancient Photosynthetic Eukaryote Biofilms in an Atacama Desert Coastal Cave [PDF]

open access: yesMicrobial Ecology, 2009
Caves offer a stable and protected environment from harsh and changing outside prevailing conditions. Hence, they represent an interesting habitat for studying life in extreme environments. Here, we report the presence of a member of the ancient eukaryote red algae Cyanidium group in a coastal cave of the hyperarid Atacama Desert.

Goods and services provided by native plants in desert ecosystems: Examples from the northwestern coastal desert of Egypt

open access: yesGlobal Ecology and Conservation, 2015
About one third of the earth’s land surface is covered by deserts that have low and variable rainfall, nutrient-poor soils, and little vegetation cover. Here, we focus on the goods and services offered by desert ecosystems using the northwestern coastal ...

Extreme environments as potential drivers of convergent evolution by exaptation: the Atacama Desert Coastal Range case.

open access: yesFrontiers in Microbiology, 2012
We have recently discovered a variety of unrelated phototrophic microorganisms (two microalgae and one cyanobacteria) in specialized terrestrial habitats at The Coastal Range of the Atacama Desert.

Monitoring of Desertification Trend Based On Analysis of Water and Climate Criterion (Southeastern Coastal Deserts of Iran) [PDF]

open access: yesمدیریت بیابان, 2014
Nowadays, desertification is one of the important ecological crises affecting the world. We require a proper understanding of causes and processes of desertification to control the serious phenomenon in the global and regional scales.
