On February 4-5, 2020 a working meeting of the project “Collaborative Data and Information Exchange Network for Managing Invasive Alien Species - DIAS” took place in Helsinki.
The participants (experts, representatives of public agencies and volunteer movements) discussed the various aspects of legislation regarding invasive species and approaches to controlling their numbers. The first draft version of the web portal “Invasive species in the Republic of Karelia” was introduced at the meeting. A key mission of the portal is to raise awareness of the issues associated with invasive species.

A successful introduction: the zander has settled down in Lake Sundozero and continues to spread
Scientists of the Institute of Biology KarRC RAS have published the results of long-term observations over the population of the zander (or pikeperch) introduced to Lake Sundozero more than a half-century ago. They confirm the species has become naturalized. Maintaining the population requires regulation of harvesting, protection during spawning, and tending of spawning grounds.

Ice-related phenomena on rivers emptying into the White Sea now last three weeks less than 60 years before
Ice on northern rivers now forms later while ice-off occurs earlier. Karelian scientists confirmed this having analyzed 64 years of marine and meteorological data from the estuaries of rivers draining into the White Sea along its western coast. Climate change has bit three weeks off the ice-covered period on these rivers. The reductions have been the most significant in the last 30 years, aligning with global warming trends in Arctic water bodies.

Citizen science and web technologies help researchers study insects of Karelia
More than 30 insect species not encountered in Karelia previously have been revealed by entomologists from KarRC RAS during their expeditions and using data communicated by active participants of the iNaturalist portal – an open platform for collecting biodiversity data.
