Plants growing at extremes follow the global rules

CREAF takes part in an international study aboy Arctic tundra leads by iDiV where they discover that tundra plants are more diverse in how they cope with cold climates than previously thought.  In a warming world, these tundra plants will benefit from having a wide range of ways to adapt to the changing climate.

The Cocoon system improves success rates when reforesting degraded land

Around 30,000 trees and shrubs were planted between 2016 and 2019 in the Mediterranean basin and the Canary Islands, with a survival rate achieved that varied between 20 and 80%, depending on the species involved. The economic analysis shows that the Cocoon system can be up to four times more profitable than the normal reforestation method.

Trees’ risk of climate change-induced death is reflected in their wood

According to a study led by the Spanish National Research Council (CSIC), the way trees have responded to drought in the past could be a key indicator of their risk of mortality. The study examined growth rings to compare that response in dead and surviving trees.

Greener springs are causing hotter, drier summers

For the first time, two phenomena that occur in different seasons are connected: the high temperatures advance and extend springs, so that the vegetation grows more intensely and absorbs more moisture from the soil. The consequence is much drier and warmer summers.

Local climate causes trees around Europe to leaf at different times

At this time of year, deciduous trees across Europe are losing the last of their leaves. When will they come into leaf again? A study just published in Nature Communications has shown that while year-to-year leafing date variations can be explained by heat accumulation, local climate is a key factor in geographical variations.

New forests grow faster but are more sensitive to climate change

A study led by CREAF has found that new forests growing on abandoned rural land are able to capture more carbon dioxide (CO2) from the atmosphere than long-established forests. This effect could be temporary, however, as the wood of their trees is less dense, making them more vulnerable to extreme climate events.

CREAF researchers study climate change-induced permafrost melt in Arctic peat bogs in Alaska

The main carbon store in the planet’s soil is peat, a deposit of plant origin found in water-saturated areas called peat bogs or peatlands. In total, peatlands contain over 550 gigatons of carbon in the form of partially decomposed plant matter, representing 42% of all soil carbon worldwide.

Cool lizards do not like global warming!

Climate change is toppling our Earth's ecosystems out of balance in multiple ways, with often dramatic consequences. Many plants and animals are already impacted. But surprisingly, it is only poorly understood which are the specific threats, and how the actual consequences will look like.

Increased CO2 only leads to faster growth in plants if they have enough water

According to a study published recently in the journal PNAS, climate change has caused forests to alter the way they grow, in that they only take advantage of the fertilizing effect of carbon dioxide (CO2) to grow faster if they have plenty of water.
