When data from each aquatic system are compared, the signals are similar, but display a delay and attenuation of the tidal signal.
Based on available data, risk to the aquatic environment from OE-P and OC appeared low.
It was assumed that risks to tadpoles could be assessed by considering toxicity data from surrogate aquatic organisms such as, e.g. fish, and that effects on terrestrial amphibians could be assessed by considering toxicity data from surrogate terrestrial vertebrates such as birds or mammals.
In all cases, only data from the same taxonomic group (i.e., aquatic invertebrates, water plants, algae or fish) were combined for prediction and comparison.
As of November 2005, the ECOTOX database included > 480,000 test records, summarizing data from > 6,000 aquatic and terrestrial species and 10,000 chemicals.
Yet, as data from aquatic systems proliferated, skeptics suggested that top-down forces might be "all wet" — limited to marine or freshwater systems, with a dearth of evidence for cascades in terrestrial systems.
Recently, stable isotope data from aquatic consumers have been used to conduct trophic niche analysis (Bearhop et al. 2004; Newsome et al. 2012).
For the next 10 months, Aros says, he received constant telepathic communication from the aquatic mammals.
Using research data from the Reef Environmental Education Foundation, collected by trained citizen-scientist divers and long-term historical data, the researchers have assembled the scientific backstory of the aquatic disaster.
