Chroomonas plurococca is a species of cryptophyte alga in the family Chroomonadaceae, found in freshwater habitats in Europe. The specific epithet plurococca, suggesting multiple or several spherical structures, may relate to a characteristic of the cell morphology such as granular inclusions or a multinucleate-appearing structure under light microscopy. Cryptophytes are a phylogenetically ancient and ecologically significant group of eukaryotic algae whose cells contain a complex plastid derived from the secondary endosymbiosis of a red alga, with retention of the red algal nucleomorph in a compressed form within the periplastidial compartment. This evolutionary feature makes cryptophytes of unique importance in understanding the evolution of complex eukaryotic cells. Chroomonas plurococca inhabits the plankton and periphyton communities of freshwater lakes and ponds in temperate regions. It contributes to primary production and participates in the microbial loop. The species has been documented from European freshwater localities. As a microalga, it has not been formally assessed for conservation status by the IUCN.

Oso Polar

El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.
