Living among these is one of the tiniest members of the Everglades plant community, periphyton algae. The base of food webs, algae floats in mats on or just below the water's ...
Once the periphyton begins to float, it supports many complex food webs. This is the beginning of many Everglades food chains in the river.We characterized food webs at 20 freshwater sites in three regions of the Florida Everglades. Sites were sampled in both the wet and dry seasons, and they encompass a wide ... representing the dominant energetic pathways in Everglades food webs (Gunderson&Loftus, 1993; Browderetal., 1994; Loftus, 2000). Ourd 13 Cdata indicate that green algae, diatoms, and ...
How do isotope data help understand food webs? Everglades poster presentations: Mapping Spatial Variability in Marsh Redox Conditions Using Biomass Stable Isotopic Compositions ... Hence, biota isotopes provide a powerful tool for monitoring how future ecosystem changes, in particular changes in hydroperiod, will affect food webs across the Everglades.
