The purpose of this research was to compare the process of microbial community development in isolated aquatic systems to the MacArthur-Wilson equilibrium theory of island biogeography and suggest alternative models for the observed patterns. Water-filled plastic containers were used as aquatic islands to investigate the colonization dynamics of protozoan, algal and microinvertebrate taxa. Polyurethane foam (PF) artificial substrates were used as sampling devices in these systems. Distance from another aquatic system was found to have a significant effect colonization in these systems.

Abstract:
Chitin belongs to the most abundant biopolymers on earth where it has an important role as a structural element in crustaceans, insects, fungi and some phytoplankton. Missing evidence for long-term accumulation of chitin in nature implies fast turnover and as chitin is composed of aminosugar subunits it holds central roles in both carbon and nitrogen cycles. The aim of this thesis was to contribute to a better understanding of organic matter cycling by learning more about the diversity, function and ecology of bacteria that degrade chitin.

Abstract:
All natural aquatic systems harbour a vast variety of microorganisms. In the aquatic microbial food web, the larger microorganisms (i.e. protozoa) feed on the smaller microorganisms (i.e. bacteria and phytoplankton). An increase in nutrient availability results in changes of the microbial food web structure, like altered community composition and blooms of toxic phytoplankton. In this thesis work I hypothesised that nutrient-rich aquatic environments, with strong protozoan predation, favour the occurrence of predation-resistant bacteria like F. tularensis, and that the microbial food web may p

Hydrological drought is a process of natural desiccation mainly due to large shortage of rainfall events. Reduced precipitations and prolonged droughts are spreading worldwide and threaten the integrity of aquatic ecosystems. Most Mediterranean streams have an intermittent flow which may become more variable and with larger duration of their no-flow periods under climate change. The enlargement of the dry period can importantly influence the ecosystem functioning, altering the microbiota inhabiting the streambed sediment as well as the processes they carry out (e.g. nutrients cycling).

Abstract:
Terrestrial inputs of organic matter contribute greatly to the functioning of aquatic ecosystems, subsidizing between 30-70% of secondary production. This contribution of terrestrial resources is especially important in boreal lakes that are largely nutrient-poor and thus more responsive to these additions.
