Entomofaunal Communities in Desert Ecosystems

2021
Desert is a natural habitat for a huge number of biotic systems (floral and faunal systems). These members depend on each other and on the already existing abiotic variables through a series of dynamic interactions to ensure their survival and kind conservation.

Productivity of Desert Ecosystems

BioScience, 1981
Primary production in desert ecosystems is limited by precipitation, nutrient availability (especially nitrogen), and the species' production potential. Plant biomass provides food for consumers that occupy several trophic levels. The resultant transfer of energy and nutrients is also water-limited as are rates of decomposition and activities of ...

Desert Rangeland Ecosystem

2020
This chapter focuses on Chinese desert rangeland ecosystems. It introduces in brief the areal extent and provincially based distribution of this ecosystem type; simply discusses the relevant physical features and climatic characteristics at a regional scale; elaborates in great detail upon the flora, fauna, and microflora composing the various desert ...

Underestimation of soil respiration in a desert ecosystem

CATENA, 2018
Abstract Soil respiration (Rs), conventionally considered as net soil CO2 flux, is an important link in the terrestrial carbon cycle. However, existing estimates of Rs in drylands may be erroneous, because of the abiotic soil CO2 flux. This may seriously hamper our understanding of the carbon cycle of desert ecosystems.

Long-Term Warming and Nitrogen Addition Have Contrasting Effects on Ecosystem Carbon Exchange in a Desert Steppe.

Environmental Science and Technology, 2021
Desert steppe, a unique ecotone between steppe and desert in Eurasia, is considered highly vulnerable to global change. However, the long-term impact of warming and nitrogen deposition on plant biomass production and ecosystem carbon exchange in a desert

On carbon sequestration in desert ecosystems

Global Change Biology, 2009
AbstractRecent reports of net ecosysytem production >100 gCm−2 yr−1 in deserts are incompatible with existing measurements of net primary production and carbon pools in deserts. The comparisions suggest that gas exchange measurements should be used with caution and better validation if they are expected to indicate the magnitude of carbon sink in ...

Bioresearches of Fragile Ecosystem/Desert

Proceedings of the National Academy of Sciences, India Section B: Biological Sciences, 2012
The proponents of anthropocene (the era of human-induced climatic changes) suggest that unless humanity changes its behavior according to earth system rules there will be no more holocene-type relative stability. Even the sustainability of the Earth’s life support systems is threatened.

Responses of plant functional trait and diversity to soil water and salinity changes in desert ecosystem

, 2019
Exploring the response of plant functional trait to environmental variations is essential to elucidate the adaptation mechanism and community assembly of desert plants under extreme environmental conditions, and more importantly to formulate strategies ...

Rapidly restoring biological soil crusts and ecosystem functions in a severely disturbed desert ecosystem.

Ecological Applications, 2016
Restoring biological soil crusts (biocrusts) in degraded drylands can contribute to recovery of ecosystem functions that have global implications, including erosion resistance and nutrient cycling.

Mercury Deposition in a Polar Desert Ecosystem

Environmental Science & Technology, 2008
Trace metals have received considerable attention in the recent decades due to their potential toxic nature. Glacial snow and ice have been used extensively to elucidate historical changes in the atmospheric composition of trace metals and other compounds.
