Five such problems are explored herein. These are: extensive infestations of water hyacinth (.), a declining native fishery, light limitation of phytoplankto

Our analysis established statistical correlations between the average reflectance values contained in video imagery (digital numbers DN per Blue-Green-Red band) and the average

Past studies provide ambiguous explanations about the role of either underground infiltration and/or runoff, relative to the lake-level fluctuation. Thus, our suspicions over the database reliability led us to inspect historic records on water levels and climatic variab

The relationship between diatom species distribution and water chemistry is explored using canonical correspondence analysis (CCA) and partial CCA. Variance partitioning indicates that ionic

The floristic composition is very similar between the freshwater cenotes. The distance of a cenote site with respect to the coastline was a determining factor in the species composition.

However, a number of key diatom species found in fossil material are not represented in the modern flora. Sampling of additional sites may resolve this, but it is thought that the lack of modern
