Seasonal acclimatization in water flux rate, urine osmolality and kidney water channels in free-living degus: molecular mechanisms, physiological processes and ecological implications.

The environmental modification of an organism's physiology in the field is often hypothesized to be responsible for allowing an organism to adjust to changing biotic and abiotic environmental conditions through increases in biological performance. Here, we examine the phenotypic flexibility of water flux rate, urine osmolality and the expression of kidney aquaporins (AQP; or water channels) in ...

A 350,000 year summer-monsoon multi-proxy stack from the Owen Ridge, Northern Arabian Sea

Five summer-monsoon proxies from the Northern Arabian Sea are combined using stacking and principal components analysis (PCA) to create two very similar multi-proxy records of summer-monsoon variability. The five individual proxies all respond to monsoon variability but are largely independent in terms of the processes that complicate their interpretation as summer-monsoon indicators (e.g. pres...

Marxism, Sarcasm, Ethnography: Geographical Fieldnotes from South India

This paper addresses questions of ethnography in geographic fieldwork through research conducted on globalisation and work in Tiruppur, an industrial boomtown in South India. During the last two decades of the twentieth century, Tiruppur town in western Tamilnad State became India’s centrepiece in the export of garments made of knitted cloth. This industrial boom has been organised through netw...

Heterothermy and the water economy of free-living Arabian oryx (Oryx leucoryx).

To test the idea that large, free-living, desert ungulates use heterothermy to reduce water loss, we measured core body temperature (T(b)) of six free-ranging, adult Arabian oryx (Oryx leucoryx) during 2 years in the arid desert of west-central Saudi Arabia. We report the first case of heterothermy in a free-living ruminant in a desert environment: T(b) varied by 4.1+/-1.7 degrees C day(-1) dur...
