We need to understand how things work, to know how to assemble and how to disassemble them. But we have reached a point of so much specialization and mechanization that too much often we can not understand how everything works, and even more, if we will be able to fix what we have broken.
The journal Nature has today published a study which had the participation of CSIC scientists at CREAF, Marc Estiarte and Josep Peñuelas, which demonstrates the relationship between the release of carbon from soils and the acceleration of climate change.
Ending perceptions of women and other disadvantaged groups simply as victims and instead empowering them as decision-makers in natural resource management are basic steps to deal with ecological crises more effectively. A new collection of studies addresses global environmental change from a feminist and interdisciplinary perspective.
CSIC and CREAF researcher Josep Peñuelas has received an honorary doctorate degree from the Estonian University of Life Sciences for his studies on global change. The university council considers his studies as excellent, and also values his international collaboration with Estonian researchers. The presentation of the award took place on September 23rd in the city of Tartu.
In the prizes to the trajectory of a scientist, people say , the hardest is to begin, because after the first award, the winner can be pretty sure that others will come. Maybe, but there are different categories of prizes. Josep Peñuelas is starting to get the big ones, those that he deserves by his contributions to ecology, his dedication and his ability to empathize in order to establish fruitful relationships with scientists all around the world.
This finding is described in an article including CREAF researchers and coauthors Aitor Ameztegui and Lluís Brotons. The study addresses how the superior limit of forest cover in the Pyrenees has changed over 50 years. According to the study, the tree line has advanced upward an average of 40 meters, one of the main causes of this being decreasing pressures from livestock. Contrary to common thinking to date, climate change may play a much lesser role than previously thought.
Climate experts, botanists, geographers and ecologists from CREAF and the Autonomous University of Barcelona (UAB) will train citizens to monitor seasonal changes which can be observed in nature. This way citizens will be able to help the scientists study the effects of climate change on animals and plants. Flower emergence, the dropping of leaves, or the arrival of certain birds will be some of the changes to be studied. Once trained, citizens will be able to contribute to European and Spanish phenology observation networks.
This phrase is often repeated among biologists, but it is time for non-biologists to recognize the truth of this statement. In the opening session of this year's course at the Institute of Catalan Studies, Jordi Casanova explained that in the light of modern knowledge, we humans are animals, considering not only in our biology (an obvious fact) but also our behavior. Many studies, mostly on apes, have shown the existence of feelings such as jealousy, envy, a sense of for injustice, rebellion; to these I would add empathy, defense of hierarchy, and a wish power.
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.
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 Europe23 de September 2015CREAF
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.
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.
MENFRI project has been featured in an interactive presentation –“How EU Research & Innovation works for a better world supporting communication activities”, prepared for EXPO 2015, showing successful EU-funded research projects.
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.
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.
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.
A new method developed by CREAF and the Autonomous University of Barcelona allows the automatic processing of thousands of satellite images taken by Landsat without manual intervention or the need of atmospheric data.
A recent study from CREAF, CTFC, and the UAB warns that if the continuity of forest vegetative cover over large parts of the territory is not reduced with urgency, catastrophic fires will become more and more common. Allowing some spontaneous fires to burn under controlled conditions could help to resolve this problem.
Mediterranean forests provide local communities with a diverse range of products such as wood, fodder for livestock and plants and game, all of which contribute to food security and help to alleviate poverty in rural regions. However, these forests will be one of the most affected ecosystems in the near future as temperatures increase and rains decrease. In order to avoid the Mediterranean region turning into a desert, expert forest management is required.
Researchers from CREAF, CSIC, and the Institute of Agricultural and Environmental Sciences of Estonia have found that flowers are becoming more fragrant as the global mean temperature rises. In addition, intense heat provokes changes in the composition of floral aromas, transforming the odors of natural areas. This could lead to pollinizers mistaking the identity of flowers, especially specialist species whose flower visits are guided by their own innate olfactory preferences.
MENFRI brings together experts to cooperate towards a profitable and sustainable use of forests in the Mediterranean6 de June 2014Anna Ramon Revilla
On May 26th 2014, experts from different countries and background (industry, policymaking, science, NGOs, etc) gathered in Morocco in the framework of the project “Mediterranean Network of Forestry Research and Innovation” (MENFRI) to assess the forestry sector organization and development opportunities in Mediterranean countries.
The BeWater project launched its first series of meetings on 28 May in La Tordera, Catalonia, Spain. CREAF, the local case study leader, together with consortium partners, met key local stakeholders in order to introduce the project, hear local perspectives on the state of the river basin and discuss potential global change impacts.
The team of Josep Peñuelas, researcher of CREAF and lecturer of the Spanish National Research Council (CSIC), was selected for a Synergy Grant, the prestigious grant offered by the European Research Council to projects by research groups of renowned excellence with interest in jointly solving vanguard research problems in the field of science.
Nightime temperatures on the planet have increased 1.4 times faster than daytime temperatures. This asymmetry alters carbon fluxes and plant growth in the northern hemisphere, according to a study in which the CREAF is participating.
According to experts at the CREAF, this capability assures success in the city and the possibility to become "urbanite" animals. A comprehensive review of published studies concludes that in urban environments, species often change their eating habits, lose their fear of humans and modify their way of communicating.
The LIFE MEDACC project (LIFE12 ENV/ES/000536 Demonstration and validation of innovative methodology for regional climate change adaptation in the Mediterranean area) is an excellent opportunity both to make the European Commission aware of Catalonia’s advances in tackling the effects of climate change laid out in the Catalan Strategy for Adapting to Climate Change (ESCACC), and to inform research institutions and technology centres of the knowledge generated.
