Eremosphaera viridis The image shows, as is typical for Eremosphaera viridis, many disc-shaped chloroplasts, each with a centrally located pyrenoid. In the pyrenoids, the cell produces the storage substance starch, which is deposited as a shell around them. Scale bar indicates 10 µm. Sample from wetland Lauchseemoor, Fieberbrunn, Tyrol, Austria. Sampling date 06/2023. The image was built up using several photomicrographic frames with manual stacking technique. Images were taken using Zeiss Axioplan with Olympus OM-D M5 MKII.

Argusino, Castilla y Len, Espaa

En Biodiversidad virtual y tambin en Instagram como @proyectoagua.En su baco de perlas diminutas Dictyosphaerium va desgranndose, abriendo su abanico verde y fresco de lunares en constelaciones blandas.Gira su cuerpo de racimo en cada gota como si fuera un infinito, saboreando el agua de cristal en la que danza levitando, y respirando la luz que va sumando a su cuerpo de galaxia nuevos brillos.Dictyosphaerium muestra su cuerpo florecido en su espejo limpio que refleja su cuerpo doblemente a cada paso, como un rbol mirndose en las aguas mansas de la orilla.Dictyosphaerium es una diminuta alga verde de cuerpo esfrico o elipsoidal que vive formando parte del plancton generalmente en zonas de aguas tranquilas. Cuando su cuerpo se divide, las dos clulas hijas resultantes, algas ya, quedan unidas por un finsimo cordn de gelatina que las mantiene unidas. Cada vez que se repite este proceso de divisin en cada una de las nuevas algas que se van agregando a la familia, se va construyendo una trama de filamentos que se disponen por parejas equilibrando la colonia que va creciendo hasta formar estas hermosas flores de agua.Las algas de algunas colonias de Dictyosphaerium , adems de estar unidas por los tenues filamentos que las sostienen en equilibrio, estn envueltas en una imperceptible envuelta de muclago que protege a toda la colonia reforzando su unin ayudndola a mantenerse en la superficie del agua.En la especie que mostramos aqu, Dictyosphaerium pulchellum, las colonias suelen ser esfricas cuando son pequeas y pueden presentar contornos irregulares cuando crecen ms. Su tamao es variable y est comprendido normalmente entre las 50 y las 100 micras de dimetro, pero siempre sus clulas, generalmente ovoides cuando son jvenes y esfricas cuando se hacen adultas, permanecen en un perfecto equilibrio que permite recibir a cada una de ellas la luz necesaria para vivir.La formacin colonial de la imagen presenta dos grupos de 36 clulas enfrentadas. Todava esta hermosa formacin podr seguir creciendo aunque el nmero mximo de individuos al que suele llegar esta especie, 64 en su equilibrio mgico.Dictyosphaerium pulchellum es muy probablemente una especie cosmopolita. Est ampliamente repartida formando parte del plancton de las masas de aguas dulces y en ocasiones suele vivir asociada a algunas plantas acuticas que viven sumergidas.Las fotografas de hoy, realizadas a 400 aumentos empleando la tcnica de contraste de fase, de interferencia, campo oscuro y epifluorescencia se han tomado sobre una muestra recolectada en en las zamoranas turberas de las inmediaciones de la Laguna de Peces en las zonas altas de la sanabresa Sierra Segundera.
