beija-flor-de-veste-preta

Um grande e marcante beija-flor de florestas tropicais do sul do México à Argentina, os manga-de-garganta-preta apresentam marcado dimorfismo sexual — os machos exibem garganta e peito negro brilhante com flancos violáceos e verdes e uma cauda roxa destacada, enquanto as fêmeas são brancas na parte inferior com uma faixa preta central. Habitam bordas de floresta, clareiras e jardins, defendendo agressivamente árvores em floração. Os machos realizam espetaculares voos de exibição na altura do dossel da floresta. Classificado como Pouco Preocupante em toda a sua ampla área de distribuição neotropical.

Chrysosphaerella annulata is a colonial freshwater chrysophyte microalga in the genus Chrysosphaerella, class Chrysophyceae. Unlike unicellular loricate chrysophytes, Chrysosphaerella species form spherical or ellipsoidal free-floating colonies in which individual cells are embedded in a common gelatinous matrix. The individual cells bear long siliceous scales with distinctive ring-like or annular structures — referenced by the species epithet annulata — projecting outward from the colony surface, giving the colony a spiny appearance under microscopy. These siliceous scales are species-specific and their morphology, as revealed through electron microscopy, is the primary character for identifying Chrysosphaerella species. C. annulata has been recorded from Norwegian and Swedish freshwater environments, consistent with the Scandinavian emphasis in chrysophyte research and the high diversity of chrysophytes in boreal freshwater systems. Chrysosphaerella colonies are planktonic, inhabiting the limnetic zone of oligotrophic to mesotrophic lakes where they may form locally conspicuous populations during favorable conditions. The species uses chlorophylls a and c with fucoxanthin for photosynthesis, contributing to primary production. Chrysosphaerella scales can accumulate in lake sediments, providing a record of past community composition and environmental conditions. C. annulata has not been assessed under IUCN criteria and is classified as Not Evaluated. Its documentation contributes to understanding the diversity of colonial chrysophyte forms in northern European freshwater ecosystems.
