Coastal Prickly-pear

Coastal prickly pear (Opuntia littoralis) is a succulent cactus in the family Cactaceae, native to the coastal sage scrub and chaparral communities of California and the northern Baja California Peninsula in Mexico. It grows on sandy dunes, rocky bluffs, and coastal slopes, often within metres of the Pacific Ocean, tolerating salt spray, summer drought, and thin, nutrient-poor soils. Like other Opuntia species, it forms flat, jointed pads armed with clusters of sharp spines and yellow glochids. Showy yellow flowers bloom in spring and early summer, producing red or purple edible fruits called tunas. These fruits are consumed by coyotes, birds, and other wildlife, making the species an important food source in coastal scrub ecosystems. The plant also provides cover and nesting sites for small reptiles and invertebrates. Coastal prickly pear is assessed as Least Concern by the IUCN. However, urban development, habitat fragmentation, and invasive plant competition threaten local populations. The species is ecologically intertwined with the highly biodiverse and endangered California coastal sage scrub biome.

koala

Icônico marsupial do leste e sudeste da Austrália, os coalas pesam até 15 kg e passam até 22 horas diárias dormindo para conservar energia de sua dieta de folhas de eucalipto, com baixo teor calórico. Altamente especializados para processar os compostos tóxicos do eucalipto que matariam a maioria dos outros mamíferos, possuem microbiomas intestinais unicamente adaptados para a destoxificação. Classificado como Em Perigo em 2022, com populações dizimadas pela doença de clamídia, desmatamento e mudanças climáticas.
