Relative abundance, diet and growth of perch (Perca fluviatilis) and roach (Rutilus rutilus) at Tvärminne, northern Baltic Sea, in 1975 and 1997: responses to eutrophication? Open
The coastal waters of the northern Baltic Sea have been undergoing a progressive process of eutrophication in recent decades. Gill net samples were taken in the Tvärminne area (SW Finland) to assess the effects of coastal eutrophication on…

Recovery of acidified lakes in Finland and subsequent responses of perch and roach populations Open
Finnish-lake and fish-status surveys indicated that 4900 small headwater lakes suffered from acidic deposition and 1600–3200 roach (Rutilus rutilus) and perch (Perca fluviatilis) populations were affected or extinct by the end of 1980s. Si…

Pike Mercury Concentration in Small Boreal Headwater Lakes During Four Decades of Regional and Local Changes Open
We measured the total mercury (THg) concentration in the muscle of northern pike ( Esox lucius L.) from 12 boreal headwater lakes once per decade during the 1980s to 2010s. Relations of pike THg to regional environmental changes, such as r…

Comparison of single- and multi-trait approaches to identify best wild candidates for aquaculture shows that the simple way fails Open
In agriculture, diversifying production implies picking up, in the wild biodiversity, species or populations that can be domesticated and fruitfully produced. Two alternative approaches are available to highlight wild candidate(s) with hig…

Ecosystem responses to increased organic carbon concentration: comparing results based on long-term monitoring and whole-lake experimentation Open
Recent increases in terrestrial dissolved organic carbon (DOC) concentrations in northern inland waters have many ecological consequences. We examined available data on carbon cycles and food webs of 2 boreal headwater lakes in southern Fi…

<b>Aging three‐spined sticklebacks</b><i>Gasterosteus aculeatus</i><b>: comparison of estimates from three structures</b> Open
In order to assess the accuracy and reliability of age estimates from calcified structures in the three‐spined stickleback Gasterosteus aculeatus , we evaluated intra and inter‐reader repeatability from three structures: otoliths, gill cov…

Food Web Responses to Artificial Mixing in a Small Boreal Lake Open
In order to simulate food web responses of small boreal lakes to changes in thermal stratification due to global warming, a 4 year whole-lake manipulation experiment was performed. Within that time, period lake mixing was intensified artif…
