Welcome to the 24th edition of the International Symposium of Cryptogamic Botany, which will be held in the city of Pontevedra (Galicia, Spain) from July 7th to 10th, 2025. The topic of this edition is Cryptogamic Diversity: Preserving the Past, Innovating the Future. With this topic we aimed to highlight the addition of two new thematic categories to this Symposium: Biotechnological Applications and Ethnocryptogamy. The purpose of this Symposium has always been to provide students, managers, educators, and researchers with the opportunity to share their research and development findings in the five fields of cryptogamy: bryology, pteridology, phycology, lichenology, and mycology. It is also important to highlight the significance of this Symposium in fostering new networks and collaborations, as demonstrated in previous editions, and which we are confident will continue to be established during this new meeting.

Understanding the response mechanism of tree growth to climate change is essential for predicting future forest dynamics in temperate regions facing significant warming and drying situations. However, the mechanisms by which trees adjust their hydraulic structure, growth and physiology in response to water stress and their effects on radial growth and canopy dynamics across different moisture environments remain poorly understood. We investigate the strategies employed by Pinus tabuliformis on dry and wet slopes of the central Qinling Mountains in China to adapt their xylem to climate variability, using anatomical indicators (theoretical hydraulic conductivity (Kh), cell wall thickness, and conduit wall reinforcement (CWR)), tree-ring width and intrinsic water-use efficiency (iWUE) derived from δ13C analyses. Contrasting drought adjustment strategies were observed on dry and wet slopes. Trees on the drier slope deployed a relatively acquisitive strategy characterized by higher Kh and lower CWR. In contrast, trees on wetter slopes adopted a relatively conservative strategy with lower Kh and higher CWR. Under increasing drought severity, trees demonstrated a rise in iWUE, which has the potential to strengthen the response of hydraulic efficiency and safety indicators to precipitation. Moreover, anatomical structure and iWUE differentially affected tree-ring width and Enhanced Vegetation Index at various growing stages. Increasing iWUE could not prevent a decline in radial growth under unfavorable moisture conditions. These findings offer foundational insights into the physiological mechanisms used by P. tabuliformis to adapt to environmental changes in temperate areas, highlighting the complex interactions among climate, anatomical and physiological indicators, and growth dynamics.

The maintenance of biological diversity at ecosystem, species and intraspecific levels is essential to ensure the survival of forests. The palaeartic yew Taxus baccata is part of a number of threatened forest types with prioritized conservation value in Europe. We investigated the spatial distribution of microsatellite genetic diversity in forty-six T. baccata populations (1,054 trees) spanning the Cantabrian-Atlantic Region (CR) in Northern Spain, framed within a conservation and restoration plan of the species in that region. Different layers of genetic structure were detected, with low structure at a global scale, suggesting historical connectivity, and a complex structure at smaller spatial scales. A low but significant regional genetic variation was also identified associated with biogeographical groups within CR, of potential interest to assist conservation and restoration programs. These genetic differences were reflected on a heterogeneous contribution to the total heterozygosity and allelic richness by the different regions. Data were contextualized within the Iberian Peninsula using previous data in this species (totaling 2,731 trees from 128 populations) after genotype standardization for a common set of seven microsatellites, confirming higher genetic diversity and more homogeneous structure in CR than in central and southeastern Iberian regions. Evidence of geographical structure between eastern (Betic Range, Catalonian Ranges, Pyrenees) and western (Cantabrian Range, Central System Range, Iberian System Range) populations was detected. This study deepens into the spatial distribution of genetic diversity in T. baccata through an intensive survey in CR as a basis for different in situ and ex situ conservation actions in the region aimed to conserve the genetic resources of this species and improve protected yew-associated natural habitats.
Palynotaxonomy of the subtribe Anisopappinae (Athroismeae, Asteraceae) and the genus Duhaldea (Inuleae, Asteraceae) based on their exine ultrastructure
(Taylor&Francis, 2023-09-27) Pereira Coutinho, António; Ortiz Núñez, Santiago; Cordeiro, Daniela; Serrano Pérez, Luis Miguel; Zuzarte, Mónica; Universidade de Santiago de Compostela. Departamento de Botánica
The exine ultrastructure of eighteen species of Anisopappus (Anisopappinae, Athroismeae, Asteraceae) and three species of Duhaldea (Inuleae, Asteraceae) was studied using Transmission Electron Microscopy (TEM). Two ultrastructural patterns were identified: Senecioid and Helianthoid. The Senecioid pattern is characteristic of the species included in the basal clades of the phylogenetic tree of Anisopappus, as published in earlier studies. The Helianthoid pattern is restricted to the taxa placed in the derived clades, including the core group of species of Anisopappus where A. chinensis, the type species, is included. The observed ultrastructural differences seem to suggest that a future splitting of Anisopappus into several different genera should not be disregarded and that the Helianthoid pattern represents, within this genus, the derived condition. The ultrastructure of the exine supports the inclusion, suggested by previous authors, of the species Duhaldea stuhlmannii, but not that of Philyrophyllum schinzii, in Anisopappus. In contrast, the three studied species of Duhaldea (D. cappa, D. nervosa, D. revoluta) present an exine with a Senecioid pattern, which is characteristic of the tribe Inuleae, in which they are included. The ectoaperture, mesoaperture, and endoaperture of all studied Anisopappinae and of Duhaldea, respectively intersect the tectum plus columellae, the foot layer and the outer part of the endexine, and the inner part of the endexine. This feature seems to characterize, in a consistent way, the “Heliantheae alliance”, and is also present in all the studied Asteroideae (excl. Anthemideae), Dicomoideae, and Carduoideae.
Nomenclature and Typification of the Jasione L. (Campanulaceae) Groups from the Eastern Mediterranean Basin
(MDPI, 2023-12-22) Serrano Pérez, Luis Miguel; Dimitrova, Lyuboslava; Ortiz Núñez, Santiago; Universidade de Santiago de Compostela. Departamento de Botánica
In this research, all the published names of Jasione (Campanulaceae) in the species, subspecies, and variety ranks for populations from the Balkan and Anatolian peninsulas are reviewed, including names of taxa allied to these groups in surrounding areas. These two areas are among the main centers of diversity of the genus, albeit no recent revisions to address the regional taxonomical complexity of the genus have been published for the Balkans and Anatolia. In this work, the taxonomic status and typification of twenty-six published names are discussed, including the plethora of names within the Jasione heldreichii, J. supina, and J. orbiculata taxonomic complexes. In total, eleven lectotypes and one neotype are designated for names from the aforementioned regions, plus one from southern Italy. This nomenclatural clarification establishes a reference for ongoing and future taxonomic and evolutionary studies of Jasione in the Mediterranean basin. In a genus prone to micro-endemism and cryptospeciation, a number of the historically described forms, despite being disregarded by current taxonomic treatments, may, therefore, deserve further attention.
Species Delimitation in a Polyploid Group of Iberian Jasione (Campanulaceae) Unveils Coherence between Cryptic Speciation and Biogeographical Regionalization
(MDPI, 2023-12-15) Serrano Pérez, Luis Miguel; Ortiz Núñez, Santiago; Universidade de Santiago de Compostela. Departamento de Botánica
Groups with morphological stasis are an interesting framework to address putative cryptic species that may be hidden behind traditional taxonomic treatments, particularly when distribution ranges suggest disjunct and environmentally heterogeneous biogeographic patterns. New hypotheses of delimitation of evolutionary independent units can lead to the identification of different biogeographic processes, laying the foundation to investigate their historical and ecological significance. Jasione is a plant genus with a distribution centered in the Mediterranean basin, characterized by significant morphological stasis. Within the western Mediterranean J. gr. crispa species complex, J. sessiliflora s.l. and allied taxa form a distinct group, occupying environmentally diverse regions. At least two ploidy levels, diploid and tetraploid, are known to occur in the group. The internal variability is assessed with phylogenetic tools, viz. GMYC and ASAP, for species delimitation. The results are compared with other lines of evidence, including morphology and cytology. The fitting of distribution patterns of the inferred entities to chorological subprovinces is also used as a biogeographical and environmental framework to test the species hypothesis. Despite the scarcity of diagnostic morphological characters in the group, phylogenetic delimitation supports the description of at least one cryptic species, a narrow endemic in the NE Iberian Peninsula. Moreover, the results support the segregation of a thermophilic group of populations in eastern Iberia from J. sessiliflora. Ploidy variation from a wide geographical survey supports the systematic rearrangement suggested by species delimitation. Taxonomic reorganization in J. sessiliflora s.l. would allow ecological interpretations of distribution patterns in great accordance with biogeographical regionalization at the subprovince level, supporting geobotanical boundaries as a framework to interpret species ecological coherence of cryptic lineages. These results suggest that species differentiation, together with geographic isolation and polyploidization, is associated with adaptation to different environments, shifting from more to less thermophilic conditions. Thus, the recognition of concealed evolutionary entities is essential to correctly interpret biogeographical patterns in regions with a complex geologic and evolutionary history, such as the Mediterranean basin, and biogeographical units emerge as biologically sound frameworks to test the species hypothesis.

Chestnut orchards (soutos in the Galician language) constitute the main feature of socio-ecological production landscapes (SEPLs) characteristic to the Northwest Iberian Peninsula. These landscapes display high levels of biodiversity that are shown in the genetic, interspecific, and ecosystem domains. They also produce a variety of ecosystem services, including cultural, regulating, and provisioning ones. Nevertheless, the interrelation between ecological functions, ecosystem services, and businesses in the present day is threatened by the abandonment of traditional management, giving way to a range of transformations that affect both the mountain landscapes and their socio-economic fabric. The objective of this study is to explore the relationships between socio-economic activities and the capacity of chestnut SEPL to preserve high biodiversity levels in the municipality of Folgoso do Courel (Galicia, NW Spain), an area with a strong tradition in chestnut production systems. To do so, we first analyse the economic structure of the area using official statistics and identifying specific businesses related to the local SEPL. We also use a geographical information system to analyse land cover maps to locate and characterize chestnut production areas. We complete our analysis by interviewing business owners to elicit important elements in the business-SEPL relationship. Our results show the strong dependence of chestnut-related businesses on the local SEPL, and how the multifunctional aspects of chestnut production are important assets in the businesses’ visions. Also, we identify risks and impacts affecting the socio-ecological production landscape. We conclude that supporting SEPL-related businesses could benefit biodiversity conservation and sustainability in the territorial system.
Deciphering uptake mechanisms of potentially toxic elements in seaweeds using high resolution imaging analysis

Pollution by potentially toxic elements (PTEs) such as Pb and Zn threatens seaweed populations, which sustain marine coastal ecosystems. Understanding how seaweeds uptake and release these pollutants is crucial to assessing their impact. To address this, we analyzed the subcellular location of PTEs in transplanted thalli of the brown seaweed Fucus vesiculosus using nanoscale secondary ion mass spectrometry (NanoSIMS). Lead accumulated primarily in the cell wall, with minimal intracellular localization. Its concentrations increased slightly upon exposure at a polluted site and decreased at an unpolluted site, reflecting an equilibrium between environmental bioavailability and cell wall binding sites. In contrast, metabolically important PTEs such as Mn and Zn exhibited higher intracellular concentrations that responded similarly when transplanted to a different site regardless of its pollution levels, likely as a stress response to changes in environmental conditions. PTEs without metabolic functions, such as Pb, are not internalized and remain in equilibrium with the environment, whereas intracellular essential PTEs are metabolically regulated. This contrast explains why PTEs differ in toxicity to seaweeds, advancing our understanding of their vulnerability to pollution and enabling more effective strategies to protect the ecosystems they support.

Shrubland vegetation plays a crucial role in ecological processes, but its conservation is facing threats due to climate change, wildfires, and human activities. Unmanned Aerial Vehicles (UAVs), or ‘drones’, have become valuable tools for detailed vegetation mapping, providing high-resolution imagery and 3D models despite challenges such as legal restrictions and limited coverage. We developed a methodology for estimating vegetation height, map vegetation classes, and fuel models by using multitemporal UAV data (imagery and point clouds from the imagery) and other ancillary data to provide insights into habitat condition and fuel characteristics. Two different random forest classification methods (an object- and a pixel-based approach) for discriminating between vegetation classes and fuel models were developed and compared. The method showed promise for characterizing vegetation structure (shrub height), with an RMSE of less than 0.3 m and slight overestimation of taller heights. For discriminating between vegetation classes and fuel models, the best results were obtained with the object-based random forest approach, with overall accuracies of 0.96 and 0.93, respectively. Although some difficulties were encountered in distinguishing low shrubs and brackens and in distinguishing low-height fuel models due to the spatial mixture, accurate results were obtained for most classes. Future improvements include refining terrain models by including data acquired with UAV aerial scanners and exploring different phenological stages and machine learning approaches for classification.

[ESP] Entre todos los recursos del bosque, los hongos presentan una gran relevancia, si bien muchos de sus potenciales utilidades son desconocidos para mucha gente. Por este motivo, el presente trabajo trata de mostrar en primer lugar, la gran diversidad que existe dentro de los hongos, y los principales aprovechamientos que el hombre puede hacer de los mismos, sobre todo en lo que se refiere a las setas silvestres. No obstante, dado que la sobreexplotación de los recursos fúngicos que se realiza en muchas ocasiones puede poner en peligro las poblaciones de numerosas especies, se comentan las principales amenazas, así como las medidas que deben ser llevadas a cabo con el fin de conservar la diversidad fúngica y lograr un aprovechamiento sostenible de los innumerables recursos que aportan los hongos, explicando un caso práctico que ha sido llevado a cabo con éxito en la Península Ibérica.
Shrub height estimation for habitat conservation in NW Iberian Peninsula (Spain) using UAV LiDAR point clouds
(Taylor & Francis, 2024-12) Rodríguez Dorribo, Patricia; Alonso Rego, Cecilia; Díaz Varela, Ramón Alberto; Universidade de Santiago de Compostela. Departamento de Botánica
This study aimed to develop and validate a method of estimating 3D parameters from DJI Zenmuse L1 LiDAR on DJI Matrice 300 RTK UAV data to characterise and monitor the structure and conservation status of dense shrub formations. The shrub heights were estimated using Progressive Morphological Filter (PMF) and the Ground Filter module of the FUSION/LDV software. A digital terrain model (DTM) was interpolated with RMSE 0.23 and 0.27 m, respectively, and a normalised canopy height model (nCHM) was calculated by subtracting it from the LiDAR data and the best DTM obtained. The reliability of the estimates was evaluated against georeferenced field data. In addition, the study examined the impact of vegetation characteristics and return reduction in the original point cloud on the accuracy of LiDAR-data derived . Significant differences were found in the correlations between observed and estimated data for the DTM (R2 = 0.9998) and nCHM heights (R2 = 0.51/0.54). The corresponding RMSE values were 0.23 and 0.34 m. Moreover, no significant differences in the reliability were found for different vegetation types, whereas reduction point cloud density (up to 25–50 returns/m2 ) did not significantly affect accuracy. In conclusion, lightweight UAV LiDAR can effectively detect sub-metric scale vegetation 3D structure, useful for fine-scale habitat conservation.
Mapping fire severity levels of burned areas in Galicia (NW Spain) by Landsat images and the dNBR index: Preliminary results about the influence of topographical, meteorological and fuel factors on the highest severity level
(University of Coimbra, 2018) Arellano Pérez, Stéfano; Ruiz González, Ana Daría; Álvarez González, Juan Gabriel; Vega Hidalgo, José Antonio; Díaz Varela, Ramón Alberto; Alonso Rego, Cecilia; Universidade de Santiago de Compostela. Departamento de Botánica; Viegas, Domingos Xavier
Fire severity assessment and mapping are essential for prioritizing post-fire emergency rehabilitation actions. The present study, carried out in Galicia (one of the regions most severely impacted by wildfire in the Iberian Peninsula), focused on 36 wildfires affecting areas of more than 200 ha during the period 2006- 2016. The aims of the study were i) to map the severity in these wildfires by using the differenced Normalized Burn Ratio (dNBR) index, and ii) to explore how the highest levels of fire severity and canopy damage are related to topographical, meteorological and forest fuel variables. Pre and post-fire Landsat images (Path 204 and Row 31), provided by the European Space Agency (ESA), were radiometrically and topographically corrected. The dNBR index was calculated for each wildfire, and the values obtained were used to establish four classes of fire severity and four levels of canopy damage. A total of 23 topographical, meteorological and fuel variables were also determined in order to characterize each wildfire. The non-parametric Random Forests method was used to relate the burned area (%) corresponding to the highest levels of fire severity and crown fire damage to the various environmental variables. The variables that best differentiated the most severely burned areas were in both cases wind speed and percentage of burned area with slope ranging from 30 to 45%.

[ESP] En este trabajo se describe la metodología empleada en la elaboración de una nueva clasificación jerárquica, basada en criterios ecológicos, estructurales, florísticos y biogeográficos, de los tipos de masas arboladas dominadas por especies autóctonas existentes en el extremo noroccidental ibérico. Para ello, se han recopilado más de 3.000 inventarios florísticos distribuidos por la geografía gallega y áreas próximas asturiano-leonesas y del N de Portugal. Como resultado, se describen un total de 93 tipos de bosques, para cada uno de los cuales se aportan sus plantas vasculares características por estratos, ambiente edafotopográfico y bioclimático en el que crecen, distribución y correspondencia con los tipos de hábitats del Anexo I de la Directiva 92/43/CEE, la clasificación de hábitats EUNIS, la Clasificación de Masas Arboladas de Europa y unidades fitosociológicas. Un número elevado de los tipos de bosques descritos no tienen correspondencia en las clasificaciones comentadas ni en el Anexo I de la DC 92/43/CEE. La elevada diversidad forestal descrita tiene un escaso reconocimiento a nivel social y dentro del sistema educativo, aspectos sobre los que se debería incidir para incrementar el grado de concienciación que la población local tiene acerca de la importancia de la conservación de los bosques a escala regional.
