Galanthus and water if disturbed by floods. Some snowdrop species are threatened in their wild habitats, due to habitat destruction, illegal collecting and climate change. In most countries collecting bulbs from the wild is now illegal. Under CITES regulations, international trade in any quantity of "Galanthus", whether bulbs, live plants, or even dead ones, is illegal without a CITES permit. This applies to hybrids and named cultivars, as well as species. CITES lists all species but allows a limited trade in wild-collected bulbs of just three species ("G. nivalis", "G. elwesii", and "G. woronowii") from Turkey and Georgia (see Horticulture). A
Chlamydomonas nivalis temperatures rise above 30 °C. It is a true snow alga because it performs better in low temperatures than warm temperatures. Due to "C. nivalis"’ ability to perform photosynthesis well from cold to moderate temperatures, this species is considered a cryotolerant mesophile rather than a cryophile. This organism is also very resilient as they can also survive in warm soil for weeks. They can also tolerate dryness and room temperature for as long as 6 months. Fungi, worms, bacteria, and viruses have been found to associate with or live in the same environment as "C. nivalis". Encapsulated rod-shaped gram-negative bacteria
