The fundamentals of conservation biology wavered

The late Finnish Professor Ilkka Hanski and his team were at the absolute forefront of metapopulation research, as evidenced by the $500,000 Crafoord Prize awarded to him. The theory, which was Hanski's area of interest, also serves as a central framework for conservation.

According to Wikipedia, "in classical metapopulation theory, each population cycles in relative independence of the other populations and eventually goes extinct as a consequence of demographic stochasticity (fluctuations in population size due to random demographic events); the smaller the population, the more chances of inbreeding depression and prone to extinction."

As conservation has also become an increasingly important sector in political decision-making, as shown by Finland's rejection of the EU Commission's proposed restoration regulation, it was interesting to note a research report published in the Proceedings of the National Academy of Sciences of the United States.

The report modeled the maintenance of the viability of metapopulations in fragmented landscapes by creating more complex, i.e., realistic, as well as simpler landscape structures. The former reflect fragmentation more realistically. The results showed that the findings from simpler models are not necessarily generalizable.

This is because dynamic phenomena that arise in more realistically fragmented landscapes often contradict the conclusions produced by simpler models. Thus, the new research undermines traditional metapopulation theory thinking - and at the same time its practical application in conservation thinking.

It remains to be seen how the research I have presented here will be covered by the European mainstream media. Or how it will affect, for example, the further development of the EU's restoration regulation. Or will it remain below the publication threshold of the media and thus not influence European conservation discussions in any way?

Since I strongly suspect that the research discussed here will remain unnoticed by the public, I decided to highlight the issue in this writing - in English and also Finnish - so that any journalist, politician, or other influencer interested in the matter - who reads this blog - could become aware of it. And could, if desired, read it themselves (the publication is open for reading) and utilize its results in their own activities.
