Advancing adaptation to climate change in marine social-ecological systems

Oceans are warming faster than terrestrial systems due to climate change, compromising marine life and dependent  human livelihoods  across the globe. We know that ecological impacts are closely intertwined with social ones due to the clomplex and interactive nature of social-ecological systems, such as fisheries or marine protected areas. However, little is know about how such systems can adapt to climate change impacts, confering resilience to the system and avoiding maladaptation outcomes. This presentation addresses how climate change is impacting key marine systems such as global fisheries, highlighting the equity and climate justice questions that arise when looking at the distribution of impact burden. Then it introduces a framework to test adaptation and transformation to climate change impacts that is tested in a series of case studies across regions. The aim is to illustrate the range of responses that individuals perform when confronting different impact levels, and what drives such responses. From coping responses that maintain the system status to adapting and transforming responses that change the structure and dynamics of the systems, we discuss the implications of response pathways. General patterns arise from the cross case study comparisons that allows to derive a general understanding of what drives adaptation and transformation changes in marine systems. Final remarks discuss how to better prepare marine systems to face climate change.

What stands between us and a post-growth science and technology era?

In an era defined by ecological collapse, deepening inequalities, and persistent techno-optimism, the idea of infinite economic growth has become increasingly untenable. In his keynote, What Stands Between Us and a Post-Growth Science and Technology Era?, Mario Pansera challenges the mainstream belief that science is neutral and technological innovation alone can solve our most pressing global problems. Drawing on his research in post-growth innovation and responsible research practices, Pansera argues that science is deeply embedded in political and economic structures that prioritize growth over sustainability and equity. He critiques the dominant narrative that positions technological fixes as panaceas for crises like climate change, insisting instead that these crises are rooted in social and political dynamics. Thus, any meaningful response must also be social and political. Pansera calls for a radical rethinking of how we do science and for whom, advocating for a post-growth approach that embraces democratic, inclusive, and context-sensitive forms of knowledge production. Only by questioning the values and power structures that shape science and technology can we begin to imagine—and build—a more just and sustainable future.

Monday 2, 19:40-20:20. Room: Auditorio

Emeritus Professor of Research at the Doñana Biological Station (EBD-CSIC).

Working on: Plant-animal interactions

Initially trained as an ornithologist, his scientific work has focused on most facets of the evolutionary ecology of plant-animal interactions, including plant-frugivore, plant-pollinator and plant-herbivore systems, as well as the tritrophic plant-pollinator-fungus system. It aims to contribute to resolving the apparent paradox represented, on the one hand, by the strong historical and ecological constraints on reciprocal adaptations found at the microevolutionary scale and, on the other hand, by the innumerable cases illustrating reciprocal adaptive radiations between plants and herbivores, pollinators and seed predators at the macroevolutionary scale. More recently, it has also added to its research programme the study of microbes potentially consequential for interactions linking plants with their animal pollinators, as well as approaches in population and molecular genetics, molecular phylogenetics, phylogeography and chemistry.

Subindividual variation, epigenetics and the melting of individuality in plants

Elucidating the causes and mechanisms involved in natural variation has historically provided a guiding thread in ecological science, and ecology has diversified into subdisciplines associated with the different, nested spatial scales at which variation occurs. The scale of variation least frequently investigated is the one which takes place within individual plants (= "subindividual variation"). Plant construction is based on the reiteration of homologous structures (e.g., leaves, flowers) which are not identical. Organ trait variance within plants often exceeds variance among individuals and subindividual variation has manifold ecological implications in terms of use of limiting resources (water, light, nitrogen), tolerance to environmental fluctuations, interactions with animals (pollinators, herbivores), and breadth of individual niches. While considerable information has accumulated on the extent and correlates of subindividual variation, a sufficiently general conceptual and mechanistic framework has been not yet agreed upon. The recent epigenetic mosaicism hypothesis postulates that the concerted action of transient, metastable and stable epigenetic differences among modules of the same plant can ultimately account for all forms of subindividual variation in plants.  Epigenetics offers a mechanistic framework for transforming information on subindividual variation (recognition, description, measurement) into knowledge (mechanisms, hypotheses, predictions). The three major epigenetic explanatory layers, along with the respective mechanisms involved, will be introduced and illustrated with empirical examples. Particular emphasis will be placed on the ecological significance of random epimutations arising from the regular 'epigenetic clock' operating in plants. Taken together, epigenetic mosaicism creates dynamic, transient epigenetic individualities nested within genetic individuals.

Tuesday 3, 9:10-10:20. Room: Auditorio

Professor of Functional Ecology,  University of Tartu.

Working on: Trait-based ecology, macroecology and biodiversity

His research aims to uncover how traits shape community assembly and ecosystem processes across different environments, scales, and organisms. He achieves this by linking traits to species performance and examining macroecological patterns of functional diversity and how they are affected by global change drivers. His work integrates experimental, analytical, and global approaches, combining field studies with the development of new methods to measure and interpret biodiversity.

Towards a unified trait space: integrating above- and belowground plant functional diversity

A multitude of traits interact to determine how plants grow, reproduce, and survive in a given environment. Different adaptive solutions in this struggle for existence have resulted in extraordinary trait diversity among vascular plants. Indeed, even standardized trait-measurement protocols, which are far from exhaustive, already encompass dozens of distinct traits. Consequently, understanding precisely which traits and trait interactions are crucial for ecological dynamics and ecosystem functioning—and under what circumstances—is challenging. A powerful approach to address this complexity is to exploit strong patterns of trait–trait coordination and trade-offs, reducing the dimensionality of trait variation into fewer independent functional dimensions.

In this talk, I will present our recent efforts to combine above- and belowground plant traits into a single unified plant functional space. These analyses have shown that, at a global scale, plants' aboveground traits provide little information about their fine-root economic strategies; notably, similar aboveground strategies can coincide with vastly different fine-root characteristics, and vice versa. Interestingly, these analyses also demonstrate a robust global coupling between plant size above- and belowground, indicating strong consistency in resource allocation patterns across plant organs.

Establishing this unified trait space provides a common framework for comparing species and communities, enabling a deeper exploration of how global environmental changes affect ecosystem functioning. Ongoing developments in methodological approaches to quantify functional structure—the way species occupy the functional space—and international initiatives expanding global trait coverage promise significant advances in ecological understanding.

Tuesday 3, 9:10-10:20. Room: Auditorio

Researcher at the Real Jardín Botánico (RJB-CSIC).

Working on: Phylogeny, Diversification, Biogeography

Her recent research combines genomic tools and macroevolutionary models to reconstruct the evolution of lineages and biomes, with particular emphasis on the patterns driving biotic assemblage over long temporal and broad spatial scales. To this end, she combine probabilistic approaches, fossils and molecular tools to reconstruct the evolutionary history of organisms at macroevolutionary scales. She is also interested in the fossil record and its integration with current evidence to provide more realistic scenarios of the past.

Deep-time paleoclimate legacies on biodiversity: from biomes to genetic-level patterns

Over the past ~100 million years, the Earth has undergone a long-term global cooling trend, punctuated by episodes of warming and abrupt temperature declines, that transformed the planet from a greenhouse to an icehouse state.

These ancient environmental changes profoundly influenced the evolutionary trajectories of life. This presentation explores how ancient long-term environmental changes shaped current biodiversity patterns across genetic, species, and spatial scales. Using a cross-taxonomic perspective, I investigate the evolutionary responses of tetrapods and plants to Cenozoic climate fluctuations, integrating phylogenies of thousands of species, fossil records, and cutting-edge macroevolutionary models. I will present three case studies in which I explore the role of climate in shaping: (1) the origin of Neotropical diversity; (2) the emergence of the Latitudinal Diversity Gradient; and (3) the spatial and temporal distribution of ancient whole-genome duplications through angiosperm history. Together, these studies reveal how deep-time climate dynamics have structured global biodiversity through a combination of ecological filtering, neutral processes, and intrinsic evolutionary mechanisms. I finally highlight how integrating phylogenetic, paleontological, and genomic data provides a richer understanding of the forces that have shaped—and continue to shape—life on Earth.

Tuesday 3, 16:40-17:50. Room: Auditorio

University Professor and Academic Secretary of the Global Change Research Institute (IICG), Rey Juan Carlos University (URJC) .

Working on: Microevolution, climate change, phenotypic plasticity

Her research mainly focuses on the evolutionary ecology of plants, particularly on the micro-evolutionary processes that occur within populations and how phenotypic variation is shaped by genetic and environmental factors. She investigates the role of phenotypic plasticity and adaptive evolution in the responses of Mediterranean plants to climate change.

Phenotypic plasticity and adaptive evolution in Mediterranean gypsum endemics: insights into climate change response

Climate change is a major threat to plant populations, especially in the Mediterranean. For gypsophiles—species restricted to gypsum soils—migration is a limited response due to specific edaphic needs, low dispersal, and fragmented distributions. Consequently, in situ processes like adaptive evolution and phenotypic plasticity are essential for their persistence. Future adaptive responses to climate change depend not only on historical evolutionary dynamics but also on the strength of selection and the evolutionary potential of functional traits and their plasticity. Our research investigates: i) the evolutionary potential of key functional traits and their plasticity; ii) whether past selection has shaped population phenotypes and plasticity patterns; and iii) the ability of gypsophiles to express adaptive transgenerational plasticity to drought. Using a quantitative genetics approach, our research shows that gypsophiles exhibit adaptive phenotypic plasticity to drought, sometimes aligned with selection patterns. High genetic variation for plasticity within populations supports their capacity to further evolve adaptive plasticity in response to climate change. This plasticity may have contributed to maintaining high genetic variation, enabling adaptation to contrasting climatic conditions. Populations of several Iberian gypsophiles display similar drought responses, likely shaped by natural selection in heterogeneous environments, and suggesting independent evolution of functional traits and their plasticity. Furthermore, gypsophiles express adaptive transgenerational plasticity to drought, though its extent varies among species. Our findings emphasize that, together, phenotypic plasticity and adaptive evolution (both past and future) play a key role in shaping population responses to changing conditions, particularly in stressful and spatially constrained habitats like gypsum outcrops.

Tuesday 3, 16:40-17:50. Room: Auditorio

Tenured scientist at the Instituto Pirenaico de Ecología, Spanish Research Council (IPE-CSIC).

Working on: Extreme environments, functional plant ecology, ecophysiology, evolution

Her research analyzes the mechanisms used by plants to adjust their form and function to the abiotic and biotic limitations of the environment where they live, and how these processes have forged plant evolution. These questions are fundamental to understanding the response of plant species to global change and its possible consequences on the functioning of ecosystems. In her research, she uses a combination of botanical, ecological, ecophysiological, molecular and physiological tools to study processes at the whole plant level. In recent years, she has specialized in the mechanisms that plants have to survive in extreme environments. Her research ranges from mountain peaks to the driest deserts of the planet, with a special emphasis on gypsum soils. 

Plant life in extreme environments: how extreme environments can help advance ecological theory

Extreme environments pose a significant challenge to the survival of most organisms. While the majority of living biomass is concentrated in relatively benign habitats, extreme environments account for a substantial proportion of the Earth's surface. Arid regions cover approximately one-third of the land coverage, and polar regions comprise around 20% of the oceanic expanse. Even within seemingly benign environments, microenvironments can create extreme local conditions (e.g., salt marshes, geothermal vents, cliffs, urban heat islands). Thus, planetary conditions are more extreme than commonly assumed. This situation is exacerbated by global change, as climate shifts and habitat destruction intensify the harshness of many regions. Today, extreme environments are more severe than ever before.

In this context, identifying the diversity that colonizes these environments and the evolutionary mechanisms developed to survive under such conditions has become an urgent challenge. These environments host highly specialized organisms that constitute a unique and often narrowly distributed biodiversity, rendering them particularly vulnerable. This diversity encompasses not only singular taxa but also unique metabolic, physiological, anatomical, and ecological adaptations. Understanding these mechanisms is essential not only for conserving this invaluable biodiversity but also as a source of technological advances and solutions to some of the most pressing environmental challenges.

Despite their importance, extreme environments are often overlooked in ecological research, and the organisms adapted to them frequently defy established biological principles. This talk is an invitation to explore the challenges posed by extreme environments and to reflect on the need to incorporate them into ecological studies aiming for truly global insights.

Researcher at the Biological Oceanography group of the CIM-UVigo and Professor at the University of Vigo.

Working on: Physical-biological interactions, phytoplankton, ocean turbulence

Her research focuses on understanding physical-biological interactions in the ocean across a broad range of temporal and spatial scales. In particular, she examines the mechanisms that control marine primary production, such as intermittent nutrient supplies to plankton communities. To do this, she uses a combination of satellite images, time-series data analysis, physical and biological observations from specific cruises, laboratory experiments, and ocean model simulations. Current topics under investigation include the role of microstructure turbulence in structuring ocean microbial communities and the role of biological nitrogen fixation in coastal upwelling systems.

Tiny but mighty: The challenge of powering life in the ocean as microscopic algae

Photosynthetic organisms such as land plants, algae, and bacteria form the foundation of food webs by producing organic matter while regulating atmospheric CO2. This presentation explores the challenges phytoplankton — responsible for nearly half of global photosynthesis — face in the ocean to power life. Unlike terrestrial plants, phytoplankton live in water, where higher density and viscosity slow physical processes and tightly couple them with biological variability. Their rapid biomass doubling times (within days) make them sensitive to short-term hydrodynamic fluctuations. Moreover, while light is available near the surface, nutrients often lie below the pycnocline, a barrier that limits upward transport. Turbulence can enhance nutrient delivery but may also displace cells into deeper, darker waters. Ramón Margalef’s 1978 mandala hypothesized that turbulence and nutrient availability control microphytoplankton succession: high turbulence and nutrient favor large diatoms, while stratified, nutrient-poor conditions support motile or efficient nutrient users like dinoflagellates and coccolithophores. However, the model originally excluded small-sized phytoplankton and relied on indirect estimates. A recent multidisciplinary dataset—from tropical, subtropical, Mediterranean, and Galician upwelling regions—has enabled the first empirical validation of Margalef’s mandala. Findings confirm the central role of nutrient supply over static concentration, and show diatoms dominate across wider turbulence ranges thanks to nitrogen-fixing symbioses and thin-layer proliferation. Finally, organisms themselves can create turbulence. In 2018, bioturbulence generated by spawning fish in the Ría de Pontevedra was shown to enhance water-column mixing, with potential implications for nutrient supply and productivity—an insight that earned the 2023 Ig Nobel Prize in Physics.

A blind spot in terrestrial carbon inventories: when water matters more than land 

Abstract: Many lakes around the world, particularly those in endorheic basins in arid and semi-arid regions, are shrinking. This poses a significant risk to the sedimentary carbon sink, as organic matter that has accumulated over thousands of years could be exposed to atmospheric oxygen, making it susceptible to remobilization. However, the current IPCC Guidelines for National Greenhouse Gas Inventories primarily account for land-use and land-cover change (LULCC) transitions from land to flooded land, and from flooded land that remains flooded. As a result, the regional estimates of the impact of LULCC on net carbon fluxes overlook areas that have transitioned from flooded land to land, even though this shift has become one of the most significant LULCC processes in many basins over the past few decades. In this study, we use data from the Aral Sea, the world's largest disappearing lake, to assess the impact of incorporating this overlooked carbon flux into existing net carbon exchange models for the Aral Sea basin. Our findings highlight a critical gap in terrestrial carbon inventories, which, if addressed, could significantly refine our understanding of carbon dynamics in these regions.
