Каштановолобый ара

A medium-sized macaw of Central and South American tropical forests from southern Mexico to Bolivia and Brazil, chestnut-fronted macaws have predominantly green plumage with a chestnut forehead, red shoulder patches, and blue flight feathers. The smallest of the true macaws, they inhabit forest edges, savannas, and secondary woodland and often raid crops, making them locally unpopular with farmers. They are popular aviary birds, but wild populations face pressure from trapping and deforestation.

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.
