Understanding the relative importance of top-down and bottom-up regulation of ecosystem
structure is a fundamental ecological question, with implications for fisheries and water-…

The sfr mutations, which result in sensitivity to freezing after cold acclimation, define genes
that are required for freezing tolerance. We tested plants homozygous for mutations sfr2 to …

Nucleation of a physical process is distinct from catalysis, and as the function of a protein it
is highly unusual. The ability to nucleate ice formation in supercooled water is a property of …

The protein product of a gene (inaZ) responsible for ice nucleation by Pseudomonas syringae
S203 has been identified and purified after overexpression in Escherichia coli. The amino …

… However, we obtained data (GJ Warren and AJ Clark, in preparation) suggesting that ColEl
repliconation also in volves recircularization. We detected recA+-independent recombination …

Data from US and Canadian federal monitoring programs are compiled to assess long-term
trends of major ions in each of the Laurentian Great Lakes. Time series are developed for …

Signs of increasing oligotrophication have been apparent in the open waters of both Lake
Huron and Lake Michigan in recent years. Spring total phosphorus (TP) and the relative …

This multi-author book brings together theoretical and applied aspects of ice nuleation from
a range of disciplines. Chapters are included on the principles of ice nucleation, the ecology, …

We describe recent trends in phytoplankton composition and abundance in the Laurentian
Great Lakes using synoptic spring (April) and summer (August) sampling events from 2001 …

… Warren, unpublished data). Few studies are available on the seasonality of cladoceran
populations in the open waters of Lake Huron, and no recent data are currently available. …
