Clay Crest

Clay-crest, Malacothrix saxatilis, is a perennial herb in the family Asteraceae native to coastal bluffs, chaparral, and rocky slopes of California and Baja California in the western United States and Mexico. The species forms sprawling to semi-erect stems with deeply lobed, grayish-green leaves and bears numerous pale white to cream-colored, dandelion-like flower heads with finely fringed ray florets. The common name refers to the chalky or clay-colored appearance of the foliage, which has a grayish, mealy texture due to fine pubescence. Clay-crest is characteristic of dry, rocky habitats, particularly coastal sage scrub and chaparral communities on calcium-rich soils of the California Floristic Province, one of the world's recognized biodiversity hotspots. The species is drought-tolerant, producing much of its growth and flowering during the cooler, wetter months of the California winter and spring before entering summer dormancy. Pollinators including bees and butterflies visit the flowers. Malacothrix saxatilis has several recognized varieties adapted to slightly different microhabitats along the Pacific coast. The species is not currently listed as threatened at the global level, though coastal development and habitat fragmentation threaten some local populations within the California Floristic Province.

koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.
