Ecosystems

Understand and manage ecosystems

Why does one species of toad live in ponds, while another prefers shingle banks? How does the flora and fauna in a mountain stream change when the glacier has melted away? And how do invasive species affect their new habitat? It is only by answering questions such as these that entire ecosystems can be understood and, to some extent, managed.

Microbial communities are known to be indispensable for our planet. But surprisingly little is known about how they function. Researchers at the aquatic research institute Eawag are now shedding a little light on this subject: A new method enables them to observe the interaction between microorganisms.

Although use of the fungicide hexachlorobenzene has been banned since 2004, this compound is chemically stable – and accumulates in the polar regions where humpback whales replenish their fat reserves each year. Cell line studies conducted at Eawag have now shown that, while hexachlorobenzene does not have acute toxic effects, it can cause damage to DNA in humpback whale cells.
