Phytoplankton Dynamics of Two Northern Prairie Lakes and Possible Relations to Dissolved Nutrients
… Enemy Swim Lake were: Anabaena, Aphanizomenon, Lyngbya, Pediastrum, Staurastrum, Dinobyron, Asterionella, Fragilaria, Melosira, Stephanodiscus, and Ceratium. All of the above genera occurred in Lake Herman except Lyngbya, Staurastrum, Dinobyron, and Melosira. Surirella was the only genus found …

A novel total synthesis of antillatoxin
… isolated to date from cyanobacterium, Lyngbya majuscule, is presented. The synthesis proceeds from commercial available trimethylacetaldehyde and produce the molecule in an overall yield of 1.1% over 15 steps. During the course of this total synthesis, 3 new methodologies were …

Ecology of algal mats and their role in the formation of stromatolites in Antarctic dry valley lakes
… primarily of Phormidium frigidum Fritsch, Lyngbya martensiana Menegh., and several species of pennate diatoms are found in the below-ice benthic regions of Lakes Bonney, Chad, Hoare, Fryxell, and Vanda, southern Victoria Land, Antarctica. Mats are also found in the littoral moats and …

Chemical studies of metabolites from Pacific Ocean marine sponges and the starfish Dermasterias imbricata
… had previously been found in the blue green alga Lyngbya majuscula collected at Enewetak. The synthetic confirmation of the tetrahydroisoquinoline substructure of the starfish metabolite imbricatine (3) was accomplished using a Pictet-Spengler reaction to couple the starting materials …

The effects of herbicide treatment on a reservoir ecosystem
… areas by 42% by two years after treatment. LYngbya sp. increased in quantity especially in the deeper areas following treatment. Floating artificial substrates were employed to monitor in situ effects of treatment on macroinvertebrates. No toxic effects due to treatment were noted. Weed …
