maracanã-guaçu

A maracanã-do-Orinoco (Ara severus) é uma arara de médio porte do gênero Ara, habitante de florestas tropicais e savanas arborizadas da América do Sul, do Panamá ao Brasil central. Possui plumagem verde com testa castanha, asas azuis e cauda avermelhada. Vive em grupos barulhentos e se alimenta de frutos, sementes e flores. Nidifica em ocos de árvores. É frequentemente mantida como ave de gaiola, sendo comercializada ilegalmente.

Colacium sideropus is a microscopic euglenoid protist belonging to the family Euglenaceae, characterized by its sessile, colonial lifestyle attaching to aquatic invertebrates and zooplankton. Members of the genus Colacium are distinguished from free-swimming euglenoids by their stalked or clustered growth form, anchoring to the bodies of crustaceans such as copepods and cladocerans in freshwater environments. Like other photosynthetic euglenoids, Colacium possesses chloroplasts derived from secondary endosymbiosis with a green alga, allowing it to perform photosynthesis under favorable light conditions. The relationship with host invertebrates is generally considered epibiotic rather than parasitic, with the protist colonizing the external surfaces of its host without causing significant harm. Colacium sideropus occurs in freshwater lakes, ponds, and slow-moving streams where its zooplankton hosts are abundant. Its ecological role includes contributing to microbial food webs and nutrient cycling within freshwater ecosystems. As with many microscopic protists, its true distribution and abundance are difficult to assess from macroscopic surveys, and it is likely globally distributed wherever suitable hosts exist in freshwater habitats.
