Nutrient consumption over time in plant litter decomposition in drylands: effects of different species mixtures and Photodegradation
(Environmental Sciences, 2021 , Professional Masters Project)
Plant litter decomposition in soil is a dynamic process that is affected and
regulated by several factors. Soil microbial activity, light intensity, litter composition
and habitat all affect the rate of decomposition ...
Meiobenthic assemblages in some intertidal areas around Qatar, Arabian gulf
(Environmental Sciences, 2021 , Professional Masters Project)
Sediment core samples were collected in 10 locations around intertidal areas of
Qatar to acquire baseline information on meiobenthic density and composition.
Temperature, salinity, and pH of interstitial waters were ...
