In "Finding Nemo," Dory, a fish with a case of aquatic amnesia who has the voice of Ellen DeGeneres, is swallowed by a whale and riffs hilariously in a tortured attempt at speaking humpback.
In the case of aquatic flora and fauna, the standard deviation of the average atmospheric measurements throughout the growing season was used.
In the case of aquatic ancestors leading to terrestrial descendants that later returned to the sea, this involved an abrupt about-face or reversal of "progress".
Observed toxicity was probably due to bioavailable fraction of dopant metals (Ni and Co) but in the case of aquatic plants, decrease of nutrient availability (complexing of phosphorus by lanthanides) was also presumed.
The chemical descriptors used in older studies had a physicochemical basis, making them useful in expressing simply the biochemical mechanism responsible for the toxic effect, mainly in case of aquatic toxicity [6].
Many ecologists define seasonal transitions by identifying biological threshold temperatures to be crossed [7], [8] and in the case of aquatic systems, the onset and deterioration of thermal stratification [9], [10] can be a useful seasonal indicator.
In the case of aquatic hyphomycete fungi, which are microscopic, submerged in water, and grow into and through opaque substrates, population genetic studies can generate unprecedented insight into otherwise unobservable biological phenomena.
For instance, animal distributions can be mapped onto physical biogeoclimatic zones, ecozones, biogeographic zones, or in the case of aquatic organisms, major drainage systems (e.g., COSEWIC 2009).
In the case of aquatic herbaceous vegetation, the flood pulse changes the availability of habitats and nutrients throughout the year, influencing the spatial distribution and the percentage of surface covered by their populations (Junk and Piedade, 1997).
Rather than such unexpected findings remaining restricted to the marine habitat, they rapidly turned out to be the norm, especially in the case of aquatic systems, e.g. the high abundances of low GC Actinobacteria in freshwater [ 4] and even in the ocean [ 5] and many other groups that are just starting to be known and studied [ 6, 7].
