Range

Distributed across Brazil, Norway, and Sweden.

Leao

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 7 distinct biome types spanning the Afrotropic and Neotropic and Oceanian realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Colombia, Ecuador, and Kenya. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Chrysochromulina cymbium is a unicellular haptophyte alga in the class Prymnesiophyceae. Its species epithet, cymbium (Latin: small boat), likely references cell morphology visible under light microscopy. Like all Chrysochromulina species, it possesses two heterodynamic flagella and a haptonema — the coiling, thread-like appendage unique to haptophytes that functions in prey capture and temporary surface attachment. The cell surface bears organic scales arranged in overlapping tiers, observable under electron microscopy. C. cymbium is a photosynthetic nanoflagellate found in coastal marine environments, where it contributes to primary productivity and carbon cycling. Scandinavian waters have historically yielded the greatest diversity of described Chrysochromulina species, reflecting intensive phycological survey effort in Norway, Sweden, and Denmark. The genus as a whole includes species capable of toxin production during bloom events, posing risks to aquaculture. No formal conservation assessment has been conducted for C. cymbium; it is listed as Not Evaluated by the IUCN. Advances in metabarcoding have revealed that environmental diversity within Chrysochromulina far exceeds the number of formally described morphospecies.

Leao

O maior felino selvagem da África, o leão pode atingir até 250 kg e é o único felídeo social, vivendo em grupos nas savanas e pastagens da África Subsaariana. Os machos se distinguem por suas icônicas juba. Como predadores de topo, regulam as populações de herbívoros e mantêm o equilíbrio do ecossistema. Classificado como Vulnerável devido à perda de habitat e ao conflito entre humanos e vida selvagem.
