Ecosystems with many and similar species can handle tougher environmental disturbances

How sensitive an ecosystem is to unforeseen environmental stress can be determined, according to Daniel Bruno, previous visiting researcher at Umeå University. The approach is to study how many species there are in an ecosystem and what proportion of these can replace species that are hard hit by en...

Do fish survive in streams in winter?

Most stream-resident fish stay throughout winter despite the ice. This has been shown by Christine Weber, previous researcher at Umeå University, by tagging trout and sculpins with transponders to follow fish migration. Fish’s general state of health is the single most important factor for surviving...

Restoring ecosystems – how to learn from our mistakes

In a joint North European and North American study led by Umeå researcher Christer Nilsson, a warning is issued of underdocumented results of ecological restorations. The researchers show that continuous and systematic evaluations of cost-efficiency, planning, implementations and effects are necessa...

Soil frost affects greenhouse gas emissions in the Arctic

Soil frost is a nearly universal process in the Arctic. In a recent dissertation by doctoral student Marina Becher at Umeå University, it is shown that the frequency and extent of soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil.

Increased spread rate of the fish round goby in the Baltic Sea

The invasive fish species round goby is spreading at an incredible rate in the Baltic Sea. In his doctoral dissertation, Magnus Thorlacius at Umeå University, presents evidence of asocial behaviour, higher risk tolerance and high activity levels in new populations correlating to the spread. Already ...

PhD student Anne Deininger wins prize for best poster

Ecosystem ecologist Anne Deininger won the prize for the best poster at the yearly staff conference at the Chemical Biological Centre, KBC. “I am of course very happy that I won a prize for my poster! The KBC-days were a good opportunity to get input from researchers outside my field, and it’s nice...

Lakes resist the introduction of new fish

In her dissertation, Anna Henriksson presents a new method of establishing how freshwater fish can defend themselves against an invasion of a new fish species. The method takes into account that resident species in a lake contribute at a varying degree to the resistance of the new species. The disse...
