Mesozooplankton Graze on Cyanobacteria in the Amazon River Plume and Western Tropical North Atlantic
Diazotrophic cyanobacteria, those capable of fixing di-nitrogen (N2), are considered one of the major sources of new nitrogen (N) in the oligotrophic tropical ocean, but direct incorporation ofExpand
Nonlinear Self-Action of Light through Biological Suspensions.
It is commonly thought that biological media cannot exhibit an appreciable nonlinear optical response. We demonstrate, for the first time to our knowledge, a tunable optical nonlinearity inExpand
The distribution and relative ecological roles of autotrophic and heterotrophic diazotrophs in the McMurdo Dry Valleys, Antarctica
ABSTRACT The McMurdo Dry Valleys (MDV) in Antarctica harbor a diverse assemblage of mat-forming diazotrophic cyanobacteria that play a key role in nitrogen cycling. Prior research showed thatExpand
Forage Fish Larvae Distribution and Habitat Use During Contrasting Years of Low and High Freshwater Flow in the San Francisco Estuary
Author(s): Grimaldo, Lenny; Burns, Jillian; Miller, Robert E.; Kalmbach, Andrew; Smith, April; Hassrick, Jason; Brennan, Colin | Abstract: Recruitment of estuarine organisms can vary dramaticallyExpand
Nonlinear transmission of light through biological suspensions
We study nonlinear light propagation through suspensions of Synechococcus cells. Such cyanobacteria in aqueous solution enable self-focusing and -defocusing of a light beam, leading to controlledExpand
