About Me

The aim of MIREN is to understand the effects of global change on plant invasions and plant biodiversity in mountainous areas. We perform observational and experimental studies along elevation gradients to evaluate and quantify the processes and mechanisms that are shaping mountain plant communities. By performing our experiments in this way we can evaluate processes at local (within site), region, and global (both comparing within and between latitudinal zones) scales.

A story of hotspots and stepping stones

Predicting the faith of exotic plant species in cold-climate mountains Abisko, a small village north of the polar circle in Swedish Lapland. The origin of several mountain trails, winding through the pristine subarctic vegetation towards the breathtaking views at the top. A vegetation mostly consisting of slow-growing mosses and dwarf shrubs that seem to have […]

Species on the move

The world’s climate is changing rapidly. There, I said it! A statement backed by scientific evidence that keeps piling up, day by day. Yet, what is perhaps even more important: the impact of this changing climate on our world are now undeniably starting to surface as well. From the damaging effect of extreme weather events, over […]

Where we disturb nature, the invaders quickly follow

Alpine vegetation in the cold north of Sweden had up till now not much to worry about incoming invaders Non-native plant invaders. Ecologists have been keeping an eye on them for a long time already. Species that flew in from somewhere far away and enter an environment where they don’t belong. Species that happily profit […]

More. Higher. Faster.

That they are creeping uphill, we noticed. That there are more of them every year, we noticed. That the lowlands are teeming with possible candidates awaiting their chance to invade the mountains, we suspected. The ever increasing, ever faster, ever higher movement of new arrivals to the alpine zone is a phenomenon that we’ve been […]

Hit the trail…for science!

Heading to the mountains this summer, armed with your favorite hiking boots? You can make a scientific contribution while you are out conquering some peaks! Your observations of a few select indicator plant species can help ecologists understand the effects of climate change and track the spread of invasive species. Citizen science bring together the […]

How to make finding a needle in a haystack seem easy

I’ve always considered fieldwork to be a kind of treasure hunt, one in which I march up and down mountains, shading my eyes against the sun in search of the next tell-tale clue. I like to imagine that this is at least how my non-science friends think about me and the fieldwork I do in […]

Botanical hitchhikers head for the hills

Roads help us to get from point A to point B. They are extremely useful structures for doing exactly that, which is why mankind has spend considerable amounts of energy to create a network of them that spans the whole globe, with tentacles reaching to the furthest deserts and highest mountain regions. But it is […]

A year without flying

It’s a conflict we all know, but it weighs particularly heavily on environmental scientists: air travel allows researchers to take part in international projects to discuss problems face-to-face, but it’s also damaging our climate and our environment. It’s a classic dilemma, and solving it will take creativity and a little sacrifice. A personal experiment. At […]

Alliances against invasions

In the discipline of mountain invasion, the enemy has many faces. Some are large and visible, marching uphill in plain sight. Others are small and sneaky, slipping invisibly and unnoticed behind your back. The problem is: it is not always the big and visible enemies that matter most. It is hard to keep track of […]
