Carotenoids in Niphargus casimiriensis Skalski (Amphipoda) from artesian wells
Carotenoids are some of the commonest pigments found in nature. They are produced only by plants, both autotrophic and heterotrophic, whereas animals obtain them through the food they eat. These pigments may, however, in the latter undergo further conversion as a result, for example, of oxidation. Various functions have been ascribed to carotenoids ranging from their participation in the photos...
متن کاملDesert Springs of the Australian Great Artesian Basin
The Great Artesian Basin (GAB) underlies about one fifth of mainland Australia. Much of this area is arid or semiarid and often artesian water is the only reliable source of potable water, historically via springs. Prior to the 1870s, there were around 3,000 flowing springs ringing the GAB. The springs were a vital source of water for Aborigines as well as early explorers, workers and pastorali...
متن کاملField estimates of groundwater discharge – Great Artesian Basin, South Australia
Understanding the water balance of large groundwater systems is fundamental for the sustainable management of the resource. However, measuring many of the major components of the water balance pose considerable challenges and are thus estimated through modelling. A shortcoming of the modelling approach is that the water balance may have high bias and uncertainty due to insufficient information....
متن کاملMolecular phylogeny and biogeography of spring-associated hydrobiid snails of the Great Artesian Basin, Australia.
The Great Artesian Basin (GAB) of Australia underlies some of the driest parts of South Australia and Queensland and feeds numerous freshwater springs. Prominent and endangered components of the GAB spring community are snails of the family Hydrobiidae. This paper examines the evolutionary relationships of the entire hydrobiid fauna associated with the GAB, and includes appropriate non-GAB spec...
متن کاملQuantifying near-surface, diffuse groundwater discharge along the south-west margin of the Great Artesian Basin
Few field measurements are available to constrain the diffuse discharge (or vertical leakage) component of the water balance of the Great Artesian Basin (GAB), even though numerical modelling indicates that it accounts for over half of the outflow of the GAB in South Australia. High leakage rates are observed along the southwestern margin of the GAB where the aquifer is close to the surface wit...
