11. Factors influencing the biogeography of bacteria in fresh waters - a metacommunity approach
Sammanfattning : One of ecology’s primary goals is to comprehend biodiversity and its patterns of distribution over space and time. Since microorganisms play a pivotal role in key ecological processes, the diversity of microbial communities may have important implications for the stability and functioning of Earth’s ecosystems. LÄS MER
12. Significance and Diversity of Lake Bacteriophages
Sammanfattning : Viruses has a relatively recently been discovered in high abundances in aquatic systems. Their possible importance has therefore been largely overlooked. LÄS MER
13. Interactions between Bacteria and Fungi on Aquatic Detritus – Causes and Consequences
Sammanfattning : Bacteria and fungi dominate the decomposition of aquatic plants, a major process in the carbon and nutrient cycling in many aquatic systems. Although phylogenetically distant, bacteria and fungi often live in close proximity with each other. Since these microorganisms also have similar ecological functions, interactions have developed between them. LÄS MER
14. Dissolved organic matter in lakes : Chemical diversity and continuum of reactivity
Sammanfattning : Dissolved organic matter (DOM) is the largest pool of organic carbon in aquatic systems and an important component of the global carbon cycle. Large amounts of DOM are decomposed within lakes, resulting in fluxes of CO2 and CH4 to the atmosphere. LÄS MER
15. Causes and consequences of Gonyostomum semen blooms
Sammanfattning : Aquatic ecosystems provide essential ecosystem services, but are also highly vulnerable to global change. Climate change, eutrophication and browning, for example, collectively drive the increase of harmful algal blooms in freshwaters. LÄS MER
