Master Thesis on Wednesday Jul 27, 2022 at 12:00 Place: IFISC Seminar Room Title: Precipitation sources and moisture transport in atmospheric rivers from a Lagrangian perspective Speaker: Alfredo Crespo, IFISC (CSIC-UIB) Abstract: Atmospheric rivers (ARs) are filaments of enhanced moisture in the atmosphere, usually located in subtropical zones and mid-latitudes over oceanic areas. Enormous quantities of water vapor travel through these structures, so that precipitation, which can be very heavy, occurs when they make landfall. This thesis presents a Lagrangian method to correctly compute the sources of precipitation in AR events. The methodology is applied to a pair of ARs that affected the Iberian Peninsula in the 1980s. The results are considered together with other more conventional approaches to study ARs, which makes us gain some insight on how water vapor is transported, and formulates interesting future research questions. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;Master thesis presentation in IFISC Seminar room, with zoom broadcasting at https://us06web.zoom.us/j/84493541497?pwd=QmwxV0tRSDNlNlZiam01S0NqQiswdz09 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Thesis advisors: Cristobal Lopez and Emilio Hernandez-Garcia &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Thesis jury: Damia Gomila, Pere Colet and Emilio Hernandez-Garcia Url event:https://ifisc.uib-csic.es/en/events/seminars/precipitation-sources-and-moisture-transport-in-at/

Talk on Friday Jul 22, 2022 at 12:00 Place: IFISC Seminar Room Title: Non-trivial interplay between immunity and human mobility shapes SARS-CoV-2 spreading Speaker: Beatriz Arregui García, IFISC (CSIC-UIB) Abstract: Abstract Since the appearance of SARS-CoV-2 in early 2020, public health systems worldwide have struggled facing the pandemic. Before having access to vaccines against Covid-19, many non-pharmaceutical interventions aimed to reduce human mobility and contacts among people were implemented. Despite all the efforts to stop the spreading, subsequent outbreaks of SARS-CoV 2 variants have occurred all around the globe leading to a heterogeneous scenario in terms of epidemic transmission and social policies. It is well known that human mobility is an important factor in propagating epidemics. However, previous works have found that the relationship between mobility and the transmissibility changes over time and have observed a decoupling between the two. We explore the interplay between human mobility and Covid-19 propagation by analysing the evolution of the major SARS-CoV 2 variants outbreaks in England.In particular, we study how different factors such as immunity, vaccination adoption and human mobility affected the epidemic spreading of different SARS-CoV 2 variants of Concern. We observe a non-trivial relation between human mobility and transmissibility: we find a high correlation between human mobility and case incidence only during a short time period of the outbreak. Outside of this time window, there is a high variability across the country. Besides, the correlation is lost when the transmissibility is very high, as it is the case with the Omicron variant.

IFISC Seminar on Wednesday Jul 20, 2022 at 14:30 Place: IFISC Seminar Room Title: Type-I excitable media: a theoretical framework for space extended excitable systems Speaker: Pablo Moreno Spiegelberg, IFISC Abstract: Excitability is a property of certain nonlinear dynamical systems concerning their response to external perturbations. Excitable systems can be classified into two classes, Type-I and II, with different dynamical properties and caused by different bifurcations. Excitable media, locally excitable spatial extended systems, show different regimes in which local perturbation exceeding a threshold can propagate across the medium. There are many studies considering Type-II excitable media, but much less is known about pulse propagation in the Type-I case. Recently, several vegetation systems compatible with Type-I excitability have shown traveling pulses, renewing interest in their study. In this seminar we will show the differences between both types of excitable media and characterize the properties of Type-I excitable pulses.

Talk on Tuesday Jul 19, 2022 at 12:00 Place: IFISC Seminar Room Title: Modelling parasite-produced marine diseases of immobile hosts Speaker: Alex Giménez Romero, IFISC Abstract: Parasite-produced marine infectious diseases pose a substantial threat to marine ecosystems and the conservation of their biodiversity. The state of the art of epidemiological studies in marine ecosystems lags behind that of their terrestrial counterparts, and only recently some none-spatial compartmental models have been proposed to describe this kind of epidemics. Furthermore, in realistic situations, epidemic transmission is conditioned by the spatial distribution of hosts, the parasites mobility patterns and the inherent stochasticity of the epidemic process. Here we developed a compartmental model for parasite-induced marine diseases of immobile hosts. First, we study in depth the non spatial version of the model based on a system of ODE&rsquo;s, finding some conserved quantities of the model and some exact and approximate reductions. Then, we study the spatially-explicit version based on an individual-based model to investigate the impact of spatial disease transmission compared to the non-spatial counterpart.

Talk on Monday Jul 18, 2022 at 14:30 Place: Zoom Seminar Title: Towards a mechanistic understanding of the assembly and disassembly of ecological networks Speaker: Miguel Lurgi, Swansea University (UK) Abstract: Ecological theory has paved the way for an understanding of the mechanisms that give rise to biodiversity patterns across temporal and spatial scales. Lessons learned include the relevance of spatial heterogeneity as well as the importance of species interactions at local scales in influencing biodiversity patterns. We are still searching for the mechanisms that give rise to certain structural features of networks of species interactions and their variation across spatial and temporal scales. This knowledge is fundamental to predict how they will respond to change. I will present my research focusing on obtaining a more mechanistic understanding of the assembly and disassembly of complex ecological networks. I adopt a mixed theoretic-empirical approach relying on the analysis of big datasets, such as the microbiome found within marine sponges or food webs comprising thousands of vertebrate species across large spatial scales, as well as the development of complex dynamical models grounded on complex systems (e.g. network dynamics, agent-based models) to elucidate the mechanisms behind community assembly and try to better understand the effects of global change on natural communities. https://zoom.us/j/98286706234?pwd=bm1JUFVYcTJkaVl1VU55L0FiWDRIUT09 Url event:https://ifisc.uib-csic.es/en/events/seminars/towards-a-mechanistic-understanding-of-the-assembl/
