+## [13] Synthesis of Neotropical Tree Biodiversity with Plot Inventories

+
+**Abstract**
+
+Tropical Americas has greater biodiversity than any other region of the world, but its biomes are under severe threat from climate and land use changes. Over recent years, plot inventory networks have successfully generated syntheses on biodiversity, ecology and ecosystem function that floristic surveys or herbarium data cannot provide. While these networks are now the basis for ecosystem and biome-level synopses, cross-biome, plot-based studies in the tropical Americas are still very rare, mainly because of the lack of cross-network harmonization. SynTreeSys has synthesized knowledge of tropical American tree biodiversity across biomes, making an unparalleled compilation of forest and savanna inventory data, in order to dissect the patterns of diversity and abundance across biomes. This seminar will present some of the achievements of SynTreeSys. We developed tools to harmonize cross-network datasets, for over 4 million trees, 13000 species and 13000 plots; we assessed patterns and drivers of tree species diversity and dominance across biomes; and we evaluated threats to tree species, and their conservation status. Beyond the science, SynTeeSys was a unique opportunity to catalyze multiple new transnational and South-North collaborations, and to foster inclusiveness.

+## [14] Towards the unification of ecological and evolutionary change
+<hr />
+
+{{< fa calendar-days >}}&nbsp; February 2026
+<br/>{{< fa user >}}&nbsp; **Alexander Duthie** (University of Stirling, Scotland, UK)
+<br/>{{< fa globe >}}&nbsp; [UNICOP](https://www.fondationbiodiversite.fr/en/the-frb-in-action/programs-and-projects/le-cesab/unicop/) project
+
+<br/>
+
+**Abstract**
+
+Biological evolution is realised through the same mechanisms of birth and death that underlie change in population density. The deep interdependence between ecology and evolution is well established, and recent models focus on integrating eco-evolutionary dynamics to demonstrate how ecological and evolutionary processes interact and feedback upon each other.
+
+The UNICOP project focuses on the logical foundations of ecology and evolution, and integrates ecological and evolutionary theory by applying eco-evolutionary models to investigate species coexistence. This seminar will present a foundational equation defining eco-evolutionary change and demonstrate how it can be used to derive fundamental equations of ecology (birth and death model) and evolution (Price equation). We outline how this framework can be used to further develop eco-evolutionary theory from first principles.
+
+In a separate approach, we analyse a model of two competing species and derive conditions under which coexistence is possible for all initial trait values. We introduce the concept of ‘near persistence’, in which coexistence holds for specific, biologically, relevant subsets of initial species traits. We show why invasion analysis must often be performed at multiple eco-evolutionary equilibria based on the ecological and evolutionary context. We discuss the biological implications of these results and perspectives for future work.

+## [15] Network of interactions in the neotropics – A field guide to mushroom networks
+<hr />

+
+<br/>
+
+**Abstract**
+
+Our project aimed at exploring the ecology of interactions involving ectomycorrhizal (ECM) fungi – that form symbioses with tree roots – in the Neotropics. Ectomycorrhizal interactions involve fungi belonging to up to 86 lineages and are often dominant in temperate and boreal forest soils – but show a scattered distribution and a lower diversity in the Neotropics as compared with other regions.
+
+Our CESAB group joined fungal and network ecologists from Brazil and France, but also Mexico, Colombia, Argentina, and United Kingdom. We aimed at gathering data from specimen and symbioses observations, specimens and root tips sequencing, and soil eDNA to explore new hypotheses explaining the peculiar ECM diversity pattern in the Neotropics. We evaluated:
+
+(1) how far the evolutionary history of Neotropical ECM differed from other regions and among lineages,
+
+(2) if environmental conditions or biogeographic history shape the present distribution of ECM in soils and
+
+(3) how these rare ECM symbioses could contribute to ecosystem stability through indirect interactions.
+
+ 
+
+For this CESABINAR, we will present our advances on these three axes, the challenges of gathering eDNA data from diverse projects and barcodes, and the perspectives for network ecology and conservation biology.
