Uptake and phytotransformation of organophosphorus pesticides by axenically cultivated aquatic plants. |
|
It is caused by an aquatic rhabdovirus, of which four strains have been identified. |
|
Restricted to the Old World, desmans have a diet consisting of aquatic invertebrates and fish. |
|
Thus it is possible that mechanisms of distastefulness evolved independently in terrestrial and aquatic parasitengones. |
|
Split beam hydroacoustics is a core technology for fisheries and aquatic habitat assessment. |
|
However as invertebrate life evolved in an aquatic habitat most have little or no specialisation for respiration in water. |
|
Thus aquatic plants, algae, and other photosynthetic organisms can live in water up to hundreds of meters deep, because sunlight can reach them. |
|
The super aquatic galleries are very simple and workmanlike, with white walls and plank floors like a ropewalk. |
|
The oceans are also a reservoir of dissolved atmospheric gases, which are essential for the survival of many aquatic life forms. |
|
Other examples of aquatic fungi include those living in hydrothermal areas of the ocean. |
|
Pine pollen is also involved in moving plant matter between terrestrial and aquatic ecosystems. |
|
Out in the water a crash of rhinoceros-like animals browse belly deep through a bed of aquatic plants. |
|
However, smooth newts are prolific breeders and can survive in a wide range of terrestrial and aquatic habitats. |
|
These are placed individually, usually under aquatic plant leaves at a rate of seven to 12 eggs per day. |
|
Lateral undulation is the sole mode of aquatic locomotion, and the most common mode of terrestrial locomotion. |
|
Others include the water vole, pipistrelle bat, grey partridge, aquatic warbler, sand lizard, great crested newt and the natterjack toad. |
|
Therefore, copper does not bioaccumulate or biomagnify in aquatic or terrestrial food chains. |
|
His research dealt with aquatic insects, especially the biosystematics of caddis flies. |
|
It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water or stalking its prey through the shallows. |
