“There are comparative grievances on the cost of living and University fees during the PhD” explains Sara Reverté17 de October 2019Verónica Couto Antelo
The CREAF ecologist has participated in a series of interviews by the English journal Functional Ecology to researchers from all over the world to learn about their experiences during the PhD and to understand how it works in each country.
Two CREAF researchers have taken part in the study, which shows that small, irregularly shaped fields on farmland boost the number and abundance of species. This is because pollinators use crop borders as highways or corridors for movement and protection. The trend of ever larger crop fields is endangering insect pollinator populations and their ability to pollinate crops
Nature establishes relationships between species and organisms, forming a very complex network where often great-interconnected nodes appear. They are called 'hubs'. But humans also create this kind of networks, such as airports as nodes and flights as connections.
Experts at CREAF say that bee populations are on the decline and that pesticides such as neonicotinoids are one of the main causes. It is important to promote organic, sustainable agriculture and move forward on the prohibition of these compounds.
A study published in the journal Biochemical Systematics and Ecologyand carried out by a team of CREAF researchers has shown that pollination by insects increases emissions of the molecules that give flowers their odors. Flower fragrances are needed to attract insects and guarantee the exchange of pollen with other flowers.
