Chisos Mountain Hedgehog Cactus

The Chisos Mountain Hedgehog Cactus (Echinocereus chisosensis) is a rare, small columnar cactus endemic to the Chisos Mountains of Big Bend National Park in Brewster County, Texas, USA. It belongs to the family Cactaceae and genus Echinocereus, the hedgehog cacti, characterised by their ribbed, cylindrical stems densely armed with radiating spines and their showy funnel-shaped flowers. This species produces striking magenta to rose-pink blooms in spring, which open during the day to attract native bee pollinators. The Chisos Mountain Hedgehog Cactus grows on rocky limestone slopes and cliffs at elevations between approximately 1,500 and 2,200 metres, where it is adapted to thin, well-drained soils and the region's semi-arid climate with seasonal summer monsoon rainfall. Its extremely restricted range — estimated at fewer than 2,000 individuals across a handful of localities — makes it highly vulnerable to stochastic events, illegal collection, and climate-driven habitat change. The IUCN classifies it as Endangered. Conservation challenges include not only its tiny range but also slow reproductive rates typical of cacti; plants may take many years to reach reproductive maturity. Big Bend National Park provides some protection, though illegal cactus poaching for the horticultural trade remains a concern for all rare Chihuahuan Desert endemics.

Epaulard

O maior membro da família dos golfinhos, as orcas (Orcinus orca) podem atingir até 9 metros de comprimento e 6 toneladas, sendo encontradas em todos os oceanos, do Ártico ao Antártico. Predadores de topo que vivem em grupos matrilineares com dialetos distintos, estratégias de caça e tradições culturais que diferem entre populações. Algumas populações se especializam em peixes, outras em mamíferos marinhos. Sem predadores naturais, as orcas ocupam o topo de todas as cadeias alimentares marinhas que habitam.
