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.

Cilician Fir

Cilician fir (Abies cilicica) is a large conifer in the family Pinaceae, native to the Taurus and Anti-Taurus mountains of southern Turkey and the mountain ranges of Lebanon and Syria, including Mount Lebanon and the Ansariyah range. It grows at elevations between approximately 1,000 and 2,400 meters in cool, moist montane forests, often forming pure stands or mixing with cedar of Lebanon (Cedrus libani), oriental beech (Fagus orientalis), and other conifers. Trees can reach 30 meters in height with a conical crown and upswept branches bearing glossy, dark green needles. The species is classified as Near Threatened by the IUCN, reflecting ongoing habitat pressures including deforestation, overgrazing, charcoal production, and the long-term effects of climate change reducing precipitation in the eastern Mediterranean. Populations in Syria and Lebanon have been severely reduced by historical forest clearance and remain highly fragmented. Turkish populations in the Taurus and Anti-Taurus are more extensive and partly protected within national parks and forest reserves. Cilician fir forests provide critical watershed protection, biodiversity habitat, and climate regulation services in a region facing intensifying water stress. Reforestation efforts using native seed sources and protection of remaining natural stands are priority conservation actions. The species is occasionally cultivated as an ornamental in European gardens.
