Chrysochromulina campanulifera is a marine haptophyte microalga belonging to the genus Chrysochromulina within the family Chrysochromulinaceae, class Prymnesiophyceae. The species epithet campanulifera, meaning bell-bearing, references a distinctive morphological feature of the cell — likely a bell-shaped scale or structural component visible under electron microscopy. This feature exemplifies how fine-scale ultrastructural characters drive species discrimination within Chrysochromulina, a genus currently containing more than fifty described species. C. campanulifera inhabits coastal marine waters and has been documented from Norwegian and Swedish coastal regions, environments that have yielded a disproportionate number of haptophyte species descriptions due to focused Scandinavian phycological research programs from the 1950s onward. The species is a nanoplankton organism — typically two to twenty micrometers in diameter — that participates in primary production and marine carbon cycling. Like other haptophytes, it possesses chloroplasts containing chlorophylls a and c along with carotenoid accessory pigments that give the cells their characteristic golden-brown coloration. The coiling haptonema, a defining feature of the genus, distinguishes Chrysochromulina from related genera such as Prymnesium and Phaeocystis. C. campanulifera has not been formally assessed under IUCN criteria and retains a conservation status of Not Evaluated. Research on this and related species informs understanding of nanoplankton diversity, marine biogeography, and the ecological dynamics of temperate and boreal coastal oceans.

koala

Icônico marsupial do leste e sudeste da Austrália, os coalas pesam até 15 kg e passam até 22 horas diárias dormindo para conservar energia de sua dieta de folhas de eucalipto, com baixo teor calórico. Altamente especializados para processar os compostos tóxicos do eucalipto que matariam a maioria dos outros mamíferos, possuem microbiomas intestinais unicamente adaptados para a destoxificação. Classificado como Em Perigo em 2022, com populações dizimadas pela doença de clamídia, desmatamento e mudanças climáticas.
