More bacteria associated to cyanobacteria than diatoms

Cyanobacteria are likely to increase with global warming and excessive nutrients in the aquatic environments, and a new study by researchers at Department of Ecology, Environment and Plant Sciences (DEEP) shows that more bacteria are associated to them as well.


European forest microclimates mapped at high resolution

A new paper, published in Global Change Biology and co-authored by researchers from the Dept. of Ecology, Environment and Plant Sciences at Stockholm University, provides novel high-resolution Europe-wide maps for monthly sub-canopy temperatures. These maps are very valuable for ecological modelling and research on climate change impacts on biodiversity. The study utilized a newly established global microclimate database (SoilTemp), for which new contributions are always welcome.


We have a new doctor at DEEP, congratulations Dr. Laura J. A. van Dijk!

Laura J. A. van Dijk defended her thesis titled "Interactions between plants, microbes and insects" the 1st of October. Discover more about her findings here.

Losses of eelgrass beds give rise to large emissions of carbon and nutrients

Losses of important eelgrass meadows in western Sweden since the 1980s have led to considerable bottom erosion and the release of carbon and nitrogen; substances that contribute to increasing climate change and eutrophication.

Zooplankton can feed on cyanobacterial blooms

Cyanobacterial blooms were until now assumed to be unpalatable for zooplankton and to sink to the sea floor. However, a new study unravels that small, rarely studied zooplankton, rotifers and ciliates, fill an important role in the Baltic Sea by grazing cyanobacteria blooms, moving carbon from phytoplankton to fish.

More diverse green sulfur bacteria in the world than previously thought

A new study based on DNA sequences shows the diversity and abundance of Chlorobia, a type of green sulfur bacteria, in several lakes and ponds around the world in Europe and North America.


PAH-levels affect the abundance of the crustacean Monoporeia affinis

Environmental contaminants have a greater impact on the Baltic Sea's bottom community than previously known. According to a new study, consideration must be given to hazardous substances when using sediment-dwelling animals to assess how affected marine areas are by eutrophication and oxygen deficiency.


Extreme drought threatens forest biodiversity

How does extreme drought affect our forests? What can we change in today's forestry to protect the important key biotopes? Follow plant ecologist Kristoffer Hylander in a research experiment to understand how extreme weather affects the forest's biological diversity.

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.


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'.


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?


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.

Forests protect animals and plants against warming

The impacts of climate warming are buffered inside forests due to the thermal insulation of forest canopies.

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.
