A competitive inhibition experimental design, incorporating radiotracer labelling of metals and the geochemical simulation of their speciation at two varying Ca water concentrations, was employed to conclusively demonstrate ...

Abstract-l. The cloaca1 and bucco-pharyngeal regions of three species of Australian freshwater turtles were ex~~mentaily compared for their ability to take up mdiocaIci~ directly from the aquatic medium. 2. The cloaca1 ...

Large animals are severely depleted in many ecosystems, yet we are only beginning to understand the ecological implications of their loss. To empirically measure the short-term effects of removing large animals from an ...

Two types of salinity tolerance information are commonly used for assessing salinity risk to freshwater organisms. These are data from laboratory experiments, usually acute (<= 96-h LC50) values, and field distributions. ...

Aerotaxis of two sulphate-reducing bacteria, the freshwater strain Desulfovibrio desulfuricans CSN (DSM 9104) and the marine strain Desulfovibrio oxyclinae N13 (DSM 11498), was studied using capillary microslides, microscopy ...

Due to the increasing amount of dry lands in the world, C4 plants which are highly efficient in water use need to be investigated as potential crop species. This study examined the arid-land agricultural potential ofseveral ...

Allometry in size and shape between sexes was investigated in preserved Bearded Dragon Pagan a barbata museum specimens. Measurements for snout-vent, head, leg and tail lengths were obtained from 236 individuals ranging ...

Changes in the species composition and structural characteristics of marine vegetated habitats in response to climate change or local anthropogenic impacts may alter their quality as habitat for associated fish and ...
