ムナグロマンゴーハチドリ

クロノドマンゴーハチドリ（Anthracothorax nigricollis）は、メキシコ南部からアルゼンチンにかけての熱帯林に生息する大型で目立つハチドリです。顕著な性的二形を示し、オスは輝く黒い喉と胸に紫・緑の脇腹と太い紫色の尾が特徴的で、メスは胸の中央に黒い縞が入る白い下面を持ちます。開花する木を積極的に守り、新熱帯区全域で軽度懸念に分類されています。

Chrysosphaerella longispina is a colonial chrysophyte alga in the genus Chrysosphaerella, notable for the long silica spines (longispina: Latin, long spine) that project from each cell in the colony. The genus is characterized by spherical or discoid colonies of photosynthetic cells that each secrete siliceous scales and elongated spine-like appendages, making Chrysosphaerella colonies distinctively bristled and visible under light microscopy. The long spines of C. longispina likely serve as anti-predation structures that make the colonies more difficult for zooplankton to ingest. C. longispina is found in cold, oligotrophic freshwater lakes, particularly in Scandinavia, where comprehensive chrysophyte surveys have documented its presence. Chrysosphaerella colonies contribute to freshwater primary production and the cycling of biogenic silica, which upon cell dissolution is deposited in lake sediments as microscopically identifiable remains. These silica structures are widely used by paleolimnologists to reconstruct past changes in lake water chemistry, thermal stratification, and climate. The conservation status of C. longispina has not been assessed by the IUCN; the species is listed as Not Evaluated.
