Internal Cycle of Seminars at IMEDEA (CISI) consist on a cycle of seminar presentations given mainly by doctoral students, masters and junior postdocs, although it is not closed to other staff, such as visitors and staff, that take place every Friday from 12:00 p.m. to 12:30 p.m in the seminar room os IMEDEA.

This represents a great opportunity to learn more about the research carried out at the Institute and to bring those with less experience , the chance of increasing their presentation and public speaking skills. Afterwards, there will be coffee and some biscuits  😉 We strongly encourage you to participate. Join us!

Internal Cycle of Seminars IMEDEA - Amparo Lázaro- «Plant-pollinator interactions in anthropized landscapes.»
Abstract Pollination is an essential process for maintaining biodiversity and ecosystem functioning, as 87.5% of the flowering plants and one third of the human diet depend on it. However, this essential ecosystem service is severely threatened by pollinator losses, raising important challenges for biodiversity conservation and crop production. Among the many threats to wild pollinators today, land-use changes have been identified as one of the main causes of pollinator declines, and this effect is expected to be accentuated in the following decades as human population increases. I will present the studies conducted in my group to understand how landscape modifications related to land-use changes affect plant and pollinator communities, the structure of plant-pollinator interactions and the provision of pollination services to crops and wild plants. The results of these studies have important implications for the sustainability of anthropized landscapes and for the conservation of pollinators as a key ecosystem service.

Geothermal energy is the cleanest and the most reliable source of renewable energy when compared to other options like solar or wind. From lighting up 5 bulbs in Italy in 1904, electricity generation from geothermal energy sources has come a long way to a total capacity of 16,355 MW (0.5% of total) by the end of 2023, most of which coming from hydrothermal reservoirs. In order to accelerate the scaling of electricity generation, Enhanced Geothermal Systems (EGS) in non-volcanic areas need to be developed. Creating these EGS requires enhancing the permeability of natural fractures through a process called hydraulic stimulation. A natural outcome of this process is microseismicity (usually Mw<2), but in a few occasions, there have been earthquakes of greater magnitude (e.g., Mw 3.4 and Mw 5.5 at Basel (Switzerland) and Pohang (Korea Republic), respectively) which were very disturbing and ended up with project cancellation. Hydraulic stimulation operations are usually designed making use of a scaling law which states that the maximum magnitude of induced earthquakes is linearly proportional to the total volume of water injected into the system. Our numerical studies on hydraulic stimulation in EGS show that the injection protocol has a stronger contribution to the maximum magnitude earthquake over the total volume of injected water.
