Estudio de Vicente Moreno Ballesteros, doctor en Historia por la Universidad Complutense de Madrid, sobre las ventas de bienes procedentes de la desamortización de Madoz en España en 1863. Proyecto de investigación dirigido por Luis Enrique Otero Carvajal, catedrático de Historia contemporánea de la UCM, integrado en el Grupo de Investigación Complutense Espacio, Sociedad y Cultura en la edad contemporánea.

Los datos GTFS del Consorcio Regional de Transportes de Madrid constituyen un conjunto estructurado de información sobre la red de transporte público, incluyendo horarios, rutas, paradas, frecuencias y correspondencias. Este formato estandarizado permite la integración con aplicaciones de movilidad y análisis de accesibilidad, facilitando el tratamiento automatizado y la interoperabilidad con otros sistemas de información geográfica o de planificación urbana.

Raw Data: Sample ID, Relative abundances and Genera Reads

• Mutations affecting crossover frequency and distribution lead to the presence of univalents during meiosis, giving rise to aneuploid gametes and sterility. These mutations may have a different effect after chromosome doubling. The combination of altered ploidy and mutations could be potentially useful to gain new insights into the mechanisms and regulation of meiotic recombination, however, studies using autopolyploid meiotic mutants are scarce. • Here, we have analyzed the cytogenetic consequences in colchicine-induced autotetraploids (colchiploids) from different Arabidopsis mutants with an altered crossover frequency. • We have found that there are three types of mutants: i) mutants in which chiasma frequency is doubled after chromosome duplication (zip4, mus81), as in the control; ii) mutants in which polyploidy leads to higher-than expected increase in chiasma frequency (asy1, mer3, hei10, mlh3); and iii) mutants in which the rise in chiasma frequency produced by the presence of two extra chromosomal sets is less than doubled (msh5, fancm). In addition, the proportion of class I/class II crossovers varies after chromosome duplication in the control. • The results obtained reveal the potential of colchiploid meiotic mutants for better understanding of the function of key proteins during plant meiosis. This is especially relevant considering that most crops are polyploids.

Our study aimed to compare the effectiveness of microscopic and DNA metabarcoding approaches in assessing the abundance and diversity of epilithic diatoms, while also exploring the suitability of metabarcoding as a reliable biomonitoring tool in Andean freshwater ecosystems. For this, 16 samples from the Guayllabamba River Basin in Ecuador were analyzed. Microscopic analysis involved the taxonomic identification of at least 600 valves under a light microscope. The molecular approach involved amplifying a rbcL region of approximately 1500 bp and conducting high-throughput DNA sequencing using Oxford Nanopore technology.
