Species Invasions

In 1991, the hydrobiid snail Potamopyrgus antipodarum (Gray 1843), native to New Zealand, was found 1 km offshore Wilson, New York, in Lake Ontario. This is the first known occurrence of the snail in eastern North America. Densities of P. antipodarum have increased since its discovery, and the snail is expected to spread quickly throughout the Great Lakes area. The biofouling potential of P. antipodarum is probably low; however, its most serious threat may be resource competition with native molluscs. This species was probably introduced in ballast water from transoceanic vessels, thus increasing the list of nonindigenous aquatic organisms introduced into the Great Lakes since the 1800s to 140 different organisms. The risk of other species invasions into the Great Lakes is still possible, despite the now mandatory ballast water regulations.

Reactive Phosphorus

The phosphorus fraction made available to organisms by the action of alkaline phosphatase, here termed phosphatase hydrolyzable phosphorus (PHP), was studied in central New York State streams. Annual mean PHP concentrations were <2.0 μg P∙L−1 for each of the four streams studied and were low relative to concentrations for lentic systems from the literature. The PHP to soluble reactive phosphorus (SRP) ratio, a measure of the relative importance of PHP for aquatic organisms, was typically in the 0.09–1.00 range, indicating that PHP could supply a significant amount of P at certain locations. Laboratory sorption experiments with varying ionic strength solutions and with Ca2+ versus Na+ suggested that PHP was probably bound to sediments by a different mechanism than SRP, one probably mediated by the organic moiety. Fine-grained sediments higher in organic matter sorbed excess PHP from solution at a greater rate than coarse-grained sediments, but also released more into PHP-depleted solutions.
