Life on Earth barely extends over its surface. But organisms have been able to transform its climate for millions of years. Now, humans seem to reach it again in a record time.

Cut leaves, collect mud, make a cellophane-type material – bees make sophisticated nests in thousands of different ways, improving their competitiveness as well as protecting them from enemies, including other bees. CREAF researcher Carlos Hernández-Castellano introduces us to this remarkable world. 

A study led by Daniel Sol, CISC researcher based at CREAF, shows that cities preserve 450 million years less evolutionary history compared to natural environments. Birds capable of surviving in highly urbanized environments have undergone recent evolution. The arrival of exotic species does not compensate for poor urban evolutionary diversity.

Jaume Terradas explains in this post how the discipline began in our country, and the capital role that some people played on it, such as Ramon Margalef and a group of young Catalan ecologists.

Some populations of the edible dormouse have become isolated due to destruction or severe alteration of their habitat. A recent study by CREAF and the Granollers Natural Science Museum shows that litters from isolated groups have more males than females since the males are the more exploratory sex charged with finding new territories. 

Forestry Hub is a digital tool for getting in touch with actors in the forestry and environment sectors, capable of effectively uniting supply and demand of services for those involved.

Pharmaceutical and personal-care products for human and animal use are increasingly released into the environment. 

A CREAF-led study shows that colonization by holm oak and other broadleaf species in the Iberian Peninsula is occurring much faster than previously thought, the main causes being reductions in forest management and climate change.
