SPATIAL AND SEASONAL PATTERN OF NUTRIENT AVAILABILITY IN LA PLATA LAKE, PUERTO RICO

Seasonal pattern of births in Puerto Rico.

It has been said that man is the only creature who eats when he is not hungry, drinks when he is not thristy and makes love all the time. If the last of these three characteristics referred to about man were true, one would expect that during, say, a period of one year, the results of this behavior of love making in terms of births would be an uniformly distributed probabilistic phenomenon.

Temporal and spatial distribution patterns of echinoderm larvae in La Parguera, Puerto Rico.

This study describes temporal and spatial abundance patterns of echinoderm larvae in La Parguera, Puerto Rico. For the temporal study, larvae were sampled by a series of monthly tows taken with a 64 microm mesh net between the new and full moon from April 2005 to July 2006, September 2006 and August 2007. In order to measure spatial variation of echinoderm larval abundances, oblique tows were t...

Spatial Spread of Epidemic Diseases in Geographical Settings: Seasonal Influenza Epidemics in Puerto Rico

Deterministic models are developed for the spatial spread of epidemic diseases in geographical settings. The models are focused on outbreaks that arise from a small number of infected hosts imported into subregions of the geographical settings. The goal is to understand how spatial heterogeneity influences the transmission dynamics of the susceptible and infected populations. The models consist...
