Small mussels in the Baltic are getting even smaller

Blue mussels in the Baltic Sea are getting smaller with time but bigger in numbers, according to a new study analyzing data since the 90's.

Caroline measuring Lathyrus vernus (spring pea, vårärt) which was trans-planted to different forest

We have a new doctor at DEEP this month, congratulations Dr. Caroline Greiser!

Caroline Greiser defended her thesis titled “Microclimate at range margins - Consequences for boreal forest understory species" on Zoom the 14th of October. Discover more about her findings here.

Climate change causing irreversible shifts in unique Asian ecosystem

Thirty-four million years ago, sudden climate change caused ecological breakdown in Central Asia. Deserts spread across the lowlands, and biological diversity was permanently affected. These are the findings by an international team, led by researchers from the University of Amsterdam, Stockholm University, and the CNRS (France). Their results are now published in the scientific journal Science Advances.

Our most talked about science: 600 plants have already been wiped off the planet the last 250 years

Some scientific publications have the opportunity to re-shape views and inspire action, to re-shuffle the academic playing cards so to speak – and one of DEEPs published papers did exactly that. Together with the Royal Botanic Gardens, Kew, DEEP’s research showed that almost 600 plants have been lost from the planet in the last 250 years. This is more than twice the number of birds, mammals and amphibians combined.


A spatial regime shift to stickleback dominance

Large numbers of three-spined stickleback have gradually taken over larger parts of the Baltic Sea’s coastal ecosystem, shows a new scientific study. Stickleback is a small prey fish common in aquatic food webs across temperate Europe. The stickleback contributes to local ecosystem ‘regime shifts’, where young-of-the-year pike and perch decline in individual bays, and these shifts gradually spread like a wave from the outer archipelago into the mainland coast.

Unrecorded plant extinction in poor countries is driven by inequality

Here we summarized five key points of the paper 'Inequality in plant diversity knowledge and unrecorded plant extinctions: An example from the grasses of Madagascar'.

COVID19 shows us that its “Time for Nature” this World Environment Day

Today, it's World Environment Day and the United Nation's way of encouraging awareness for the protection of our environment.


New study could help predict plant species responses to climate change

A new global study which could help to predict plant species losses and responses to climate change and warming has been published.

How tough are grasses: The cost of surviving cold and frost

Jan-Niklas Nuppenau, PhD student at DEEP, is studying grasses growing on soils heated by volcanic activity in Iceland, to find out if they can deal with heat and cold likewise. Or are the costs of maintaining cold tolerance so high, that the ability is lost quickly when no longer needed?

A hidden treasure: Stockholm University´s green house plant collection

Up on the rooftop at Department of Ecology, Environment and Plant Sciences (DEEP) hides a green treasure in a realm of light. It’s DEEPs greenhouse and used for both teaching biology students about plants, as well as for research purposes.

The weird and wonderful world of grasses: 6 things you did not know about grasses

When you hear the word “grass” you typically think of a green lawn neatly grown in a garden or park. However, the world of grasses entails so much more. Discover more in the blog post.

Climate change is not the only threat for our plants

To maintain plant and animal species on Earth, we need not only to consider the direct effects of climate change, but we must also take other equally important environmental issues into consideration.

Better pollination produces firmer apples that better withstand storage

Good pollination of apple flowers can extend the time apples can be stored without rotting. Apple harvests are also bigger, producing firmer and tastier apples.

Almost 600 plants have already gone extinct

Almost 600 plants have been wiped out from the planet in the last 250 year shows a new study. This is twice the number of birds, mammals and amphibians combined.

The gene helping submerged plants

Climate change threatens plants as the risks of flooding increase. A new study from Stockholm University shows that special genes are key to keeping plants from withering, remaining healthy and resistant to a lack of oxygen when they are underwater for a period of long time.

Use your power to treat your colleagues well!

Department of Ecology, Environment and Plant Sciences (DEEP) organized a workshop aiming to prevent the misuse of power. Now they hope that other departments at SU will follow in their footsteps.

Migratory birds, insects and plants adapt differently to climate change

A warmer climate has caused plants flowering and migratory birds arriving earlier in the year than before. Now a global study also shows that changes in the life cycles between plants and animals that depend on each other is also moving faster.
