Home chemical and microbial transitions across urbanization

Fermented Camel Milk (Chal): Chemical, Microbial and Functional Properties

The aim of this study was to determine physicochemical, microbial properties and antioxidant activity of fermented camel milk (Chal) and introduce it as a functional food. The protein content of the samples was determined using Kjeldahl method and total dry matter using oven drying method. The amount of fat content with Gerber method and pH was measured using a pH meter. Antioxidant activity wa...

Microbial biogeography: patterns in microbial diversity across space and time

Walls talk: Microbial biogeography of homes spanning urbanization.

Westernization has propelled changes in urbanization and architecture, altering our exposure to the outdoor environment from that experienced during most of human evolution. These changes might affect the developmental exposure of infants to bacteria, immune development, and human microbiome diversity. Contemporary urban humans spend most of their time indoors, and little is known about the mic...

The Soundscapes of Lakes across an Urbanization Gradient

UNLABELLED BACKGROUND/METHODOLOGY: A significant implication of increasing urbanization is anthropogenic noise pollution. Although noise is strongly associated with disruption of animal communication systems and negative health effects for humans, the study of these consequences at ecologically relevant spatial and temporal scales (termed soundscape ecology) is in early stages of application. I...

Planktonic microbial community composition across steep physical/chemical gradients in permanently ice-covered Lake Bonney, Antarctica

Lake Bonney is a chemically stratified, permanently ice-covered Antarctic lake that is unusual because anomalous nutrient concentrations in the east lobe suggest that denitrification occurs in the deep suboxic waters of the west lobe but not the east lobe, resulting in high concentrations of nitrate and nitrite below the east lobe chemocline. Environmental factors that usually control denitrifi...
