Jun 27, 2023 · The environmental regulatory mechanism underlying the coupling of leaf photosynthesis and transpiration in Artemisia ordosica, a typical desert shrub in China, remains unclear. To understand this mechanism, we measured the net leaf photosynthetic rate (Pn), transpiration rate (E), and stomatal conductance (gs) from May to October 2019 using a portable photosynthesis analyser ...
Jun 10, 2022 · Many studies suggest that species diversity and abiotic factors promote ecosystem multifunctionality. However, whether ecosystem multifunctionality is impacted by phylogenetic diversity remains controversial. The present study tested this in an arid desert ecosystem in Ebinur Lake Basin using soil C:N ratio, soil pH, and soil salinity as abiotic factors, and species diversity and phylogenetic ...
An ecosystem is a geologically and geographically defined environment in which certain organisms live. The ecosystem describes a system in which the organisms interact with each other (such as through predation or symbiosis) and the environment (such as building dens, photosynthesizing, and more).
Mostly, deserts occur in specific latitudes (25 to 35° north and south of the equator). Deserts are arid where less than 250 mm of rain falls in a year resulting in low soil water availability, sparse growth of vegetation, and low productivity. However, evaporation exceeds rainfall in these ecosystems.
Jan 18, 2024 · Abiotic factors in cold deserts are low precipitation, extreme temperatures (both hot and cold), lack of humidity, sandy and rocky soils, and exposed bedrock. Summary. The desert ecosystem is the driest ecosystem on the planet. The desert ecosystem is a group of living and nonliving things that live together and interact with each other in a ...
Sep 1, 2021 · The desert-oasis ecotone is the connecting zone between the desert ecosystem and the oasis ecosystem. Its material and energy exchanges are frequent, and the ecological environment is fragile. It can either evolve into an oasis or degenerate into a desert, and the difficulty of evolution is much higher than that of degradation ( Tang et al ...
Jan 17, 2024 · Importance of studying abiotic factors in the Sahara Desert. Examining the abiotic or non-living components of the Sahara Desert environment is important for understanding this extreme ecosystem. Abiotic factors shape the desert’s biodiversity patterns, species adaptations, ecosystem processes, and human livelihoods.
