Vie 23rd Feb 4:00 pm 5:00 pm | AbstractIn this presentation, we will explore the various tasks undertaken by the Fish Ecology Lab at the Palma Fish Market since 2018. Our focus lies in automating the processes employed for extracting fish length measurements. The dynamic distribution of fish lengths plays a crucial role, not only in making informed short-term operational decisions within a fishery co-management framework but also in providing input for traditional fishery models that illuminate mid- and long-term trends in exploited stocks. Traditionally, the estimation of fish length in most fisheries has been a manual endeavor, resulting in precise measurements at the individual fish level. However, due to the high cost and inefficiency associated with supervised sampling, the sample size tends to be limited. Consequently, the precision of population-level estimates often falls short, and biases may arise, especially when adequately stratified sampling programs are economically unfeasible. Conversely, the application of machine learning and artificial intelligence in fisheries science presents a promising avenue for large-scale, unbiased sampling of fish catches. The Fish Ecology Lab has been working with the daily images recived from the auction of the fish market to extract information on various commercial species such as hake, dolphinfish, and red shrimp. This presentation will specifically focus into the deep learning techniques employed for each of these cases. Sala de seminarios IMEDEA | |||||||||||||||||||||||
Sáb 2nd Mar 12:00 pm 1:30 pm | Mesa Redonda sobre Posidonia oceànica y entrevista a Jorge Terrados durante la celebración de la Diada de Les Illes Balears Amb motiu de la celebració de la Diada de les Illes Balears, es durà a terme una sèrie d'entrevistes a diferents investigadors de les Balears, entre ells, a Jorge Terrados, de l'IMEDEA. A continuació, us deixem el programa complet:
Divulgació de la recerca sobre Posidonia oceànica
Dia: 2 de març de 2024 Lloc: Carpa Govern a Parc de la Mar Presenta i modera: Enric Culat
12h: Nona Sheila Agawin (UIB) Temes: ecologia de Posidonia oceànica; ecologia de microorganismes associats a Posidonia oceanica que tenen funcions importants (pe fixadors de nitrogen); l'efecte dels factors del canvi climàtic (canvis de temperatura, CO2 a Posidònia oceànica); l'efecte dels contaminants (plàstics i components de cremes solars) sobre P. oceanica i microogranismes associats.
12:15h Jorge Terrados (IMEDEA) Temes: Una investigació de l’IMEDEA i altres centres de recerca aplica un nou enfocament més eficient a través de models matemàtics de simulació i l'anàlisi de xarxes de connexió per avançar així en la comprensió de la Posidònia oceànica i poder restaurar-la. L'impacte que té la pèrdua de les praderies de posidònia a la biodiversitat local. El paper específic de la Posidònia oceànica a l'ecosistema marí de les Pitiuses. Els avenços tecnològics i les eines innovadores que s'estan utilitzant per monitoritzar i estudiar les praderies de posidònia. Els beneficis econòmics i socials de conservar les praderies de posidònia a Mallorca a llarg termini. La forma per involucrar els sectors turístic i empresarial en la conservació de les praderies de posidònia a Mallorca.
12:30h Damià Gomila (IFISC) Temes: Un nou estudi impulsat des de l'IFISC i altres centres de recerca mostra que els patrons espacials a les praderies de posidònia, com la Posidònia oceànica, es poden explicar per la interacció del creixement de la posidònia i la reflexió de les onades oceàniques. Els investigadors proposen que aquest mecanisme podria millorar la capacitat d’aquests ecosistemes costaners per reflectir l’energia de les onades, protegint així les costes d’inundacions i de l’erosió. Els autors creuen que la formació de patrons espacials permet que les praderies de posidònia reflecteixin més fortament l'energia de les onades entrants. Això afegeix al seu valor com a formes naturals de protecció costanera contra l’augment del poder de les onades oceàniques induït pel canvi global. Aquest estudi emfatitza encara més la necessitat de protegir aquests crucials ecosistemes costaners, i podria inspirar els gestors costaners a emprar millor les praderies de posidònia com a defenses contra inundacions basades en la natura.

Vie 8th Mar 4:00 pm 4:30 pm | AbstractWarming can have dramatic effects on plant phenology and reproduction, with important consequences for reproductive output, plant survivorship, or species dispersal. In seagrasses, vegetative growth through clonal expansion is generally the dominant strategy for meadow maintenance, expansion and recovery, with sexual reproduction strongly differing amongst species, being rare for some, and some times associated with disturbance. Even rarer is the occurrence of pseudovivipary, an uncommon phenomenon in the plant realm, which has only been reported twice before in the marine environment as highly localized phenomena associated with environmental stress. Pseudovivipary is an asexual reproduction strategy whereby plantlets replace sexual reproductive structures, leading to the maintenance of the maternal clones. In summer of 2022, the Mediterranean Sea underwent unprecedented warming, and, associated with it, we observed extensive flowering (100% of sites) as well as pseudovivipary across numerous (>85 % of 36 sites) Posidonia oceanica meadows along the Balearic Islands. Our results support the notion that P. oceanica flowering is triggered under high warming but also, and importantly, this is the first time ever that pseudovivipary is reported across so many locations in a marine plant, and the fate of these plantlets is being monitored by assessing development, survivorship and dispersal through time. Considering the negative impacts that warming can have on seagrass ecosystems, the discovery of widespread pseudovivipary is a critical aspect to consider for understanding mechanisms of resilience in seagrasses.

Lun 11th Mar 9:00 am to Mié 13th Mar 3:00 pm | The threat and occurrence of high-magnitude, uncontrolled induced seismicity has been a persisting issue in several kinds of subsurface systems for decades now. Research on limiting induced seismicity to improve the safety of these systems began ever since the first observed cases in wastewater injection. The number of groups working to solve this problem only increased with every major event, focusing on various aspects of induced seismicity. Our understanding of the underlying processes has improved consistently, but the recent events at Pohang, Castor, Groningen, etc., have showcased that there is more to learn in terms of the physics, and demand better characterization, monitoring and forecasting systems in place.
This Workshop aims at fostering debate on the latest advances in process understanding, subsurface characterization and forecasting of induced seismicity. We welcome contributions from the academia and industry alike in topics ranging from, but not limited to numerical modeling, laboratory experiments, field studies, application of AI in induced seismicity, etc. We welcome contributions in the form of both posters and oral presentations that broadly fit into the following sessions:
Session 1: Understanding of the causes of induced seismicity Session 2: Post-injection seismicity: can we forecast it? Session 3: Subsurface characterization Session 4: Forecasting induced seismicity Session 5: Case Studies of induced seismicity

Mar 12th Mar 10:00 am 11:00 am | TREC: a scientific voyage to address environmental challenges Dr Kiley West Seitz - EMBL TREC (TRaversing European Coastlines) is the European Molecular Biological Laboratory’s flagship Scientific expedition to study coastal ecosystems at molecular level. The expedition studies coastal regions which are known for their extremely rich biodiversity and plays a critical role in the stability and sustainability of ecosystems at planetary scale. These ecosystems are drastically affected by global changes & local human impacts making the study of them critical to understanding the climate crisis. For the TREC expedition, we employ a holistic cross sectional sampling approach along the land-sea gradient using highly standardized protocols. This systematic approach allows us to study the coastal ecosystems at the molecular level across pollution gradients, organismal scales, life complexity and time scales. The TREC expedition started in April 2023 and is expected to last until end of July 2024. During that time, the researchers will be gathering biological samples and environmental data along the European coastline at more than 120 land-sea transects. Mallorca is one of the sampling sites of the expedition, and IMEDEA is hosting and supporting the TREC team during their campaign on the island. As part of this seminar you will learn about the project and you will visit the traveling labs parked at IMEDEA.

Jue 14th Mar | One of the main challenging problems in evolutionary molecular biology is understanding the mechanisms that led to the emergence of chemical digital coding from inanimate matter. While recent advances, such as the identification of fougerite as a putative coding material have been made, there are currently no reasonable theoretical models describing this transition. The primary objective of this interdisciplinary workshop is to bring together scientists from the fields of physics, mathematics, biology, and computer sciences to address two key questions central to the present COST action:
The Workshop will contribute to the integration of Dynamical System concepts on the interrelation between coding and decoding along the flux of biological information and related aspects on the theories of the origin of life. Moreover, will favor the development and exchange of knowhow, integration, training, and promotion of specific collaborations in the modelling of genomic information. The anticipated outcome of this activity will serve as an integrative synthesis, interweaving the research threads developed in the Bolzano and Porto Conferences and Workshops. In doing so, it will consolidate the findings related to the application of the dynamical systems approach in understanding the fundamentals of the flow of genetic information. The spirit of DYCOMAT is to actively promote collaboration among its participants. In this regard, the organization intends not to be a mere sequence of informative talks but mainly to foster effective collaborative working tables to address the specific objectives of DYNALIFE.

Vie 22nd Mar 4:00 pm 4:30 pm | AbstractMarine macrophyte ecosystems are considered as a fundamental habitat throughout the world. However, these communities are seriously threatened by the continuous increase in anthropogenic activities and are highly vulnerable to the pressures derived from global change. This has led to an increased interest in restoration, and in assessing different factors that may promote their recovery and resilience. In seagrasses, firsts life stages (seeds and seedlings) can be critical when determining the natural recovery of the ecosystem. In this sense, identifying the factors that positively influence the development and establishment of these early stages, particularly considering future stressors, is essential for ecosystem conservation and restoration. The study of microbiome can be a determining factor to understand the functionality and resilience of marine ecosystems. Although the study of seagrass microbiomes is still in its early stages, the beneficial effect of microorganisms has already been described in terrestrial plants, so this study aims to evaluate the influence of microbiome on germination and development of C. nodosa seeds.
To test the hypothesis that the presence of certain microorganisms influences the development of seagrass, a manipulative factorial experiment was carried out in the laboratory using C. nodosa seeds. Six treatments from the interaction between two factors were examined: (1) sterilization (or not) of the seeds and (2) sediment type (sediment from vegetated environments, sediment from non-vegetated environments or artificial sediment). Germination success was strongly influenced by the presence of the seed microbiome, and sediment type (and thus soil microbiome) also influenced germination and seed development. These results are important to understand natural drivers of seagrass germination success and to consider for restoration techniques. Sala de Seminarios del IMEDEA, Esporles | |||||||||||||||||||||||

Vie 12th Abr 11:30 am 12:00 pm | AsbtractGeothermal 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.

Vie 26th Abr 12:00 pm 12:30 pm | AbstractThe generation and propagation of waves towards the coastal regions during storm events can substantially increase coastal hazards associated with extreme sea levels. While the Mediterranean Sea is characterized by a fetch-limited environment, the progression of extra-tropical cyclones over its surface often engenders powerful waves. As climate numerical models consistently converge towards a global warming climate over the past few decades, the present wave climate is expected to undergo alterations. However, the reliability of the model projections differ among climate variables, exhibiting for instance higher confidence in the temperature than in precipitation variables. This study investigates future changes in the wave climate across the Mediterranean region using an extensive ensemble of wave numerical simulations. These simulations were forced with wind fields from thirty-one GCM-RCMs (general circulation - regional climate models) of the European Coordinated Regional Climate Downscaling Experiment (EURO-CORDEX), integrating WaveWatch III and SCHISM numerical models. Future changes in the mean and intense (quantile 0.95) wave climate of significant wave height (Hs), peak wave period (Tp), peak wave direction (Dp) are assessed. Furthermore, we evaluate changes in 100-year return levels of Hs toward the end of the century. Extreme events from each GCM-RCM are aggregated into a single coherent distribution, following a bias correction procedure assuming the Cumulative Distribution Function (CDF) of extreme events to adhere to either a parametric Gumbel or Generalized Extreme Value (GEV) CDF, individually for each model. Return levels are then computed by fitting a GEV distribution to the unified distribution for both historical and future periods. Our findings reveal an intensification of extreme waves towards the end of the century in several areas of the Mediterranean basin. Despite limitations inherent to bias-correction methods and return level computation, our study underscores the contrasting outcomes between analyzing the entire statistical distribution versus focusing solely on the tail, emphasizing the importance of considering both aspects in wave climate projections.

Vie 3rd May 12:00 pm 1:00 pm | AbstractSunlight drives virtually all life on the Earth’s surface, with about 50% of primary productivity occurring in marine systems. Yet, this traditional view of phototrophy changed radically with the discovery of marine bacterial rhodopsins (i.e., proteorhodopsins; PR), over twenty years ago. PRs are simple light-driven proton pumps present in over 80% of surface bacterioplankton, which allow them to transform light into biochemical energy. Combining culture-based physiology studies with (meta)-genomics, (meta)-transcriptomics, and environmental quantifications we are just starting to understand the role that PR-based photoheterotrophy plays in the ocean. In this presentation, I will discuss the knowns and unknowns of PR-phototrophy and what we are starting to learn from looking at its natural distributions in different oceanographic basins, ranging from extreme ultraoligotrophic regions to high productivity environments Sala de seminarios IMEDEA | |||||||||||||||||||||||

Mar 7th May 12:00 pm 1:00 pm | SEMINARIO JB Raina (UT Sydney) - Uncovering complex chemically mediated microbial behaviours Abstract The ability of marine bacteria to direct their movement in response to chemical gradients influences inter-species interactions, nutrient turnover, and ecosystem productivity. While natural chemical hotspots produce gradients comprised of hundreds to thousands of different chemical compounds, we do not know how this chemical diversity affects the chemotactic responses of bacteria. I will present results from two studies that reveal some unexpected responses when bacteria are exposed to complex chemical mixtures. Using in situ and laboratory-based assays, we show that marine bacteria are strongly attracted to the abundant algal polysaccharide laminarin, but chemotaxis towards this large molecule is enhanced by dimethylsulfoniopropionate (DMSP), another ubiquitous algal-derived metabolite. Our results indicate that DMSP acts as a methyl donor for marine bacteria, increasing their gradient detection capacity and facilitating their access to polysaccharide patches. Using a novel chemotaxis choice assay, we then directly expose a model marine bacterium to four potent chemoattractants simultaneously (i.e., one monosaccharide and three amino acids). Although the bacterium is strongly chemotactic to each of these molecules in isolation, when these four molecules are provided simultaneously, the cells exhibit a striking response by swimming towards only one of them. These results start shedding light on the synergistic effects (e.g., laminarin and DMSP) and sharp chemical preferences modulating the behaviours of bacteria.

Mié 8th May 10:45 am 12:00 pm | INTERNATIONAL VISITING SCHOLAR PROGRAMME (IVSP) Abstract Seagrass meadows and the services they provide are declining worldwide as a result of human perturbations. Along the Swedish W coast, almost 60% of the seagrass has been lost since the 1980's, representing a loss of approximately 190 km2 of seagrass. The seagrass Zostera marina, L. (eelgrass) is the dominant macrophyte on soft bottoms along the Swedish coast. The decrease in seagrass worldwide has lead to many restoration programs but their success rate is very low due to the regime shift and feedback mechanisms that also prevent natural recovery. This presentation aims to provide a review on the restoration successes and challenges on eelgrass in Sweden. For example, positive feedbacks generated by water turbidity due to sediment resuspension, drifting macroalga covering eelgrass transplants and the presence of eelgrass predators such as shore crabs have been identified as causes affecting restoration success. To overcome these issues, restoration techniques using sand-capping have shown to be successful to reintroduce eelgrass in areas where it was lost. An interdisciplinary approach using field and laboratory experiments linked with hydrodynamical modeling showed to be key to understand the complex coastal ecological dynamics. In addition, new methods to monitor coastal habitats such as seagrass meadows and marine mammals (dugongs and seals) using aerial drones and machine learning will be presented. These new technologies can contribute to faster data collection and data analysis for ecological studies and to provide relevant information to coastal managers and decision makers working on ecological conservation. Bio Eduardo Infantes is a researcher at the University of Gothenburg in Sweden, where he leads the Seagrass Ecology Lab research group based at Kristineberg marine station. With a focus on seagrass ecology over the last 18 years, his main interests are in 1) studying interactions between fluid dynamics and marine vegetation through field data, mesocosm experiments and flume studies, 2) restoration of coastal habitat using seagrass within the interdisciplinary ZORRO group, and 3) monitoring of seagrass beds and marine mammals (e.g. harbor seals, manatees, and dugongs) using drones and AI. With an interdisciplinary profile, he collaborates in research and management, contributing to environmental policies in coastal restoration and monitoring.

Vie 10th May 12:00 pm 12:30 pm | AbstractEstablishing root systems in rhizome fragments of Posidonia oceanica presents a significant challenge for its restoration. Rhizome fragments of this slow-growing seagrass require robust rooting for successful anchorage and nutrient absorption from the environment. Controlled experiments have demonstrated that the use of plant growth regulators, such as the auxins α-naphthaleneacetic acid (NAA) and indole-3-butyric acid (IBA), stimulates rooting in P. oceanica cuttings. However, this effect has not been tested in a marine environment. In this study, rhizome fragments were exposed to varying concentrations of NAA and IBA for 24 hours before transplanting into a dead matte area in the Bay of Pollensa (Mallorca, Spain). After one year, all fragments survived; however, contrary to expectations, no significant differences emerged in the growth and biomass of roots, rhizomes (orthotropic and plagiotropic), and leaves between treated and untreated fragments. This implies that applying auxins to P. oceanica rhizome fragments may not offer an advantage when rooting transplants in the marine environment. Future studies should explore how other environmental conditions can influence rooting and interactions with auxin effects over time.

Vie 17th May 12:00 pm 12:30 pm | Abstract
The animal gut hosts diverse bacterial communities that can affect the individual’s behavior, physiology, and metabolism. However, the relationship between an individual’s microbiome and its social behavior in the wild is poorly understood. We tested the hypothesis that social behavior in the wild is correlated with the gut microbiome composition in a marine fish (Xyrichtys novacula). Relying on high-resolution acoustic telemetry, we first obtained a high-quality positioning data set from 232 individuals (153 females and 79 males). From these data, we computed the associations between paired individuals and found a harem-like social structure. Territories were formed by one male and several females, and males displayed agonistic behaviors towards their neighbors to defend territories. Subsequently, a sample of the social network was captured, and the diversity of the gut microbiome was quantified using operational phylogenetic units (OPUs) based on the analysis of 16S rRNA gene amplicons using Illumina high throughput sequencing. The social network properties were strongly correlated to the gut microbiome. Individual microbiome samples of fish from the same harem (including from different sex) were more similar to each other, while differences to other harems were strong. The use of similar local microhabitats, including food resources, as well as local social contact can both provide key transmission pathways for gut symbionts that shape gut microbiota, structuring the microbiome along social networks in aquatic animals. This work is among the first to show a relationship between social structure and the microbiome in a fish species in the wild. Further work is needed to reveal cause-and-effect relationships into whether the social network shapes the microbiome or the microbiome and the resulting metabolites shape certain behaviors that in turn create the network structure.

Vie 24th May 12:00 pm 12:30 pm | Abstract
Seed predation and dispersal play key roles in the regeneration of tropical trees. Seeds may escape pre-dispersal predation when ingested with the fruit pulp and moved away from the parent trees by frugivores. Frugivore species may influence dispersal quality differently even when feeding on the same fruit species. In southern Mexico, we investigated if seed traits (i.e., length, width, and mass) and germination success differed among seeds ingested by howler monkeys (Alouatta pigra), spider monkeys (Ateles geoffroyi), and non-ingested seeds. For this, we recorded the germination rate and percentage of seeds from five tropical tree species, including the following: Ampelocera hottlei , Brosimum lactescens , Dialium guianense, Spondias mombin and Spondias radlkoferi. Furthermore, only for D. guianense we determined if there was a primate selection towards seeds with no insect damaged. Results showed that traits of seeds ingested by howler monkeys differed from those ingested by spider monkeys and non-ingested seeds; while seeds ingested by spider monkeys were similar to non-ingested seeds. Howlers consumed on average the larger seeds. For all five tree species, germination rate was greatest for seeds ingested by howler monkeys. The proportion of damaged seeds declined significantly from non-ingested seeds (48 %), to seeds in spider monkey feces (29 %), and finally to seeds in howler monkey feces (7 %). Fruit selection by primate species influences dispersal quality differently, even when feeding on the same plant species. Howler monkeys may increase the reproductive success of the studied tree species by selecting larger and predation-free seeds/fruits. Sala de Seminarios del IMEDEA, Esporles | |||||||||||||||||||||||

Vie 7th Jun 12:00 pm 12:30 pm | AbstractThe Southwestern Atlantic Ocean (SWA), is considered one of the most productive areas of the world, with a high abundance of ecologically and economically important fish species. Yet, the biological responses of this complex region to climate variability are still uncertain. Using 24 years of satellite-derived Chl-a data, the SWA was classified into 9 spatially coherent regions based on the temporal variability of Chl-a concentration, as revealed by SOM (Self-Organizing Maps) analysis. These biogeographical regions were the basis of a regional trend analysis in phytoplankton biomass, phenological indices, and environmental forcing variations. A general positive trend in phytoplankton concentration was observed, especially in the highly productive areas of the northern shelf-break, where phytoplankton biomass has increased at a rate of up to 0.42 ± 0.04 mg m −3 per decade. Significant positive trends in sea surface temperature were observed in 4 of the 9 regions (0.08–0.26 °C decade −1) and shoaling of the mixing layer depth in 5 of the 9 regions (−1.50 to −3.36 m decade −1). In addition to the generally positive trend in Chl-a, the most conspicuous change in the phytoplankton temporal patterns in the SWA is a delay in the autumn bloom (between 15 ± 3 and 24 ± 6 days decade −1, depending on the region). The observed variations in phytoplankton phenology could be attributed to climate-induced ocean warming and extended stratification period. The provided results further evidence of the impact of climate change on these highly productive waters. Sala de Seminarios del IMEDEA, Esporles | |||||||||||||||||||||||
