Water Content and Insect Metabolism

Metabolism and water loss rate of the haematophagous insect Rhodnius prolixus: effect of starvation and temperature.

Haematophagous insects suffer big changes in water needs under different levels of starvation. Rhodnius prolixus is the most important haematophagous vector of Chagas disease in the north of South America and a model organism in insect physiology. Although there have been some studies on patterns of gas exchange and metabolic rates, there is little information regarding water loss in R. prolixu...

Water and Electrolyte Metabolism II

I have followed the lysosome field since it was proposed as a concept by deDuve and his co-workers in 1955 and find this collection of papers by workers in that field an interesting addition that has many sparkling con-addition, of course, to deDuve, to name a few) but it also has several several shortcomings. For the uninitiated (and there are surprisingly many for whom "lysosome" is a new wor...

Water-saving irrigation strategies affect tuber water relations and nitrogen content of potatoes

The dynamic and static deficit (DDI, SDI), partial root drying (DPRD, SPRD) and full (FI)irrigation strategies were applied in Agria and Ramos potato cultivars in a semi-arid area. FIreceived 100% of the potential evapotranspiration (ET); SDI and SPRD received 75% of ETduring the growth period; DDI and DPRD received 90% of ET in the first third, 75% of ET inthe second third and 50% of ET in the...
