Birds and butterflies are key indicators for the measurement of biodiversity loss

According to a study in which CREAF participated, the populations of birds or butterflies living in open habitats have been negatively affected by the loss of field and scrubland habitat. Conversely, species which live in forests have been favored. These variations were related with changes in the Catalonian (and Mediterranean) landscape over the last few decades.

Agriculture and forestry increase the production world ecosystem biomass by 15%

CREAF has participated in an international study which has estimated the total biomass production of all planetary ecosystems. These data can be used to improve accounting of the global supply of natural resources and plan strategies for boosting the sequestration of atmospheric carbon.

The response of leaf unfolding phenology to climate warming has significantly reduced in Central Europe

Leaf unfolding occurred on average about 4 days earlier every one degree increase in spring temperature between 1980 and 1994, whereas this value dropped to -2.3 days C-1 between 1999 and 2013, a decrease of over 40%. According to this study recently published in the jorunal Nature with the participaction of Josep Peñuelas, researcher from CSIC at CREAF, warmer winters and photoperiod are forcing plants to control their phenology calendars.

Is environmental education working?

In the year 1970, an international meeting was held, organized by IUCN and UNESCO, on Environmental Education in the School Curriculum, at the Foresta Institute of Carson City, Nevada. One of the results of that meeting was the first largely accepted definition of environmental education, a concept born perhaps a couple of years before and mainly developed at the United Kingdom.

Increased daytime temperatures is causing earlier leaf emergence

A study led by a CREAF-CSIC researcher has outlined a new methodology for describing changes in the life cycle of plants caused by planetary warmingwith higher precision. Daytime, rather than nocturnal temperatures determine phenological changes. The increase in temperatures, leading to an earlier spring, alters the global functioning of ecosystems.

The youngest ecosystems are those most sensitive to climate change

CREAF participated in a study which proposes that in order to understand the full impact of climate change, it is not enough to study just protected natural areas, which are mature and able to handle change; instead, it is important to focus on the study of those ecosystems which have been altered and are still recovering.

Human activity may be supporting growth of harmful algae in lakes

The organisms commonly known as blue-green algae have proliferated much more rapidly than other algae in lakes across North America and Europe over the past two centuries – and in many cases the rate of increase has sharply accelerated since the mid-20th century, according to an international team of researchers led by scientists at McGill University with CREAF and CSIC researchers.
