Since the early 1990s phytoplankton has been studied and monitored in Potter Cove (PC) and Admiralty Bay (AB), King George/25 de Mayo Island, South Shetlands. Phytoplankton biomass is typically low compared to other Antarctic shelf environments, with …
Periphyton is an aquatic community composed by algae, bacteria, fungi, and other microorganisms that can develop a complex architecture comparable to tropical forests. We analyzed the spatial pattern of a periphyton community along a succession …
We analyzed the relationship between biodiversity and spatial biomass heterogeneity along an ecological succession developed in the laboratory. Periphyton (attached microalgae) biomass spatial patterns at several successional stages were obtained …
Recent theoretical works on the dynamics of metapopulations have highlighted the existence of very long transients (supertransients) with abrupt changes in behaviour which occur following perturbation of the system away from its attractor. If this …
The collection of time-series of periphyton biomass is a difficult task due to the destructive nature of the standard methods. A non-destructive method based on photography and digitalization, for the estimation of Chla of periphyton colonizing …
The short-term biomass dynamics of periphyton communities in running water is characterized by deep variations. This temporal variability is mainly produced by changes in running water velocity. The shear force caused by the friction of water over …
Spatially explicit models like cellular automata are widely used in ecology. The spatio-temporal order of events is a new feature of these models that does not have to be considered in equivalent non-spatial models. We considered simple stochastic …
