Spatial and temporal distribution of populations selected to represent trophic structure

A population is a group of organisms of the same species. Like canaries in the coalmine, changes in populations of organisms can be important indicators of environmental changes.

Predator: prey size relationships of marine zooplankton: Testing the 10:1 hypothesis with stable isotopes

Poster Number:  395 Presenter/Primary Author:  Michael Landry Size-based theories of energy flow in marine plankton ecosystems, as well as numerous conceptual models, assume that predators and prey are linked, on average, by a body length ratio of 10:1. 

Forest metacommunity structure along an elevational gradient in the Luquillo Mountains, Puerto Rico (LUQ)

Poster Number:  394 Presenter/Primary Author:  Jess Zimmerman Metacommunity theory provides a rich framework for identifying structure along environmental gradients and for evaluating the relative contributions of local and regional processes in molding biolo

Pelagic community responses to a deep-water front in the California Current Ecosystem: The CCE A-Front Study

Poster Number:  386 Presenter/Primary Author:  Michael Landry In October 2008, we investigated pelagic community composition and biomass, from bacteria to fish, across a sharp frontal gradient overlying deep waters south of Point Conception, California. 

Zooplankton aggregation at glider-detected ocean fronts in the California Current Ecosystem

Poster Number:  376 Presenter/Primary Author:  Jesse Powell Here we report the results from six years of front observations from 2006 through 2011 along two transect lines within the Southern California Current System (SCCS) using autonomous gliders.
