A review and classification of the existing models of cyanobacteria
Modelling of cyanobacteria in freshwaters is an important tool for understanding their population dynamics and predicting bloom occurence in lakes and rivers. In this paper existing key models of cyanobacteria are reviewed, evaluated and classified

Cyanobacteria (blue-green algae) have become an issue of increasing concern to water-resource managers in recent years. Cyanobacterial blooms form when a large population migrates to the lake surface. Vertical migration is controlled
by the physiological response of the cyanobacteria to changes in hydro-environmental conditions. The role of modelling in management is considered and an alternative schematic model to calculate the cyanobacterial light-budget is presented. Such a model could form

This paper reports on a laboratory wind tunnel based comparison of the stability of mono-specific crusts formed by each of 3 selected photoautotrophs: Chlamydomonas acidophila, Lyngbya sp., and Nostoc commune. Only filamentous cyanobacteria

crust, a predominantly physically (depositional) crusted loess soil sparsely colonised by cyanobacterial filaments, and a loamy hillslope soil supporting a well-developed crust colonised by cyanobacteria lichens, and some mosses. The AA. examine

Valleys. The results cast doubt as to whether high-level lakes existed in the McMurdo Dry Valley as recently as the early Holocene. An alternative explanation is that the former lakes had no effects on soils other than depositing deltas with cyanobacteria

Nuisance cyanobacterial blooms are an important environmenttal pproblem. The sustainable management of toxic cyanobacteria would increase the conservation and amenity value of affected water bodies, and decrease on-site water treatment costs

and other fresh and brackish lakes of the Vestfold Hills. Cyanobacteria and protists were also recovered from the core samples. The occurrence of this trophically diverse assemblage of organisms at an early stage in the evolution of the lake suggests either

) by reallocating related abiotic resources at small- and medium-scales in the Tengger Desert. Their results showed that higher soil pH and higher total potassium content in topsoil positively correlated with the colonization of cyanobacteria and algae
