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.

Population, Community, and Metacommunity Dynamics of Terrestrial Gastropods in the Luquillo Mountains: A Gradient Perspective

Poster Number:  210 Presenter/Primary Author:  Michael Willig Elevational variation in the Luquillo Mountains of Puerto Rico creates strong environmental gradients that affect the abundance and distribution of species.  Moreover, the geographic mappings

Spatial Configuration of Multiple Aspects of Biodiversity Along a Tropical Elevational Gradient

Poster Number:  209 Presenter/Primary Author:  Michael Willig Although taxonomic biodiversity is a multidimensional concept, most research at intermediate to broad spatial scales has solely considered gradients of species richness.  In contrast, we quant

Resource allocation among arctic char in closed arctic lakes:

Poster Number:  196 Presenter/Primary Author:  Phaedra Budy In closed arctic lakes, we observe a strong cycle in population structure in arctic char (Salvelinus alpinus) while population abundance remains generally stable.  We hypothesized this cycle w
