ciliate fringewort

Ciliate fringewort (Ptilidium ciliare) is a leafy liverwort in the family Ptilidiaceae, found in boreal and montane regions of the Northern Hemisphere, including Europe, North America, and parts of northern Asia. It grows as a creeping, irregularly branched mat with leaves divided into deeply fringed lobes edged with long, hair-like cilia—the characteristic feature that gives the species its common name. Ciliate fringewort colonizes a variety of substrates including rock surfaces, boulders, tree trunks, and peaty ground in open to moderately shaded habitats such as heathland, moorland, montane grasslands, and subalpine and subarctic vegetation. It is particularly common on exposed rocks in boreal and tundra zones. The species is classified as Endangered in parts of Europe, where lowland populations have declined severely due to atmospheric nitrogen deposition, afforestation of open heathland, and the loss of traditionally managed heath and moorland habitats. Populations in montane and boreal zones remain more stable. Ciliate fringewort is sensitive to elevated nitrogen levels that promote the competitive dominance of grasses and mosses. Restoration of lowland heathland and reduction of nitrogen pollution are key measures needed to support remaining European populations. The species is better represented in Scandinavian boreal habitats and North American taiga and tundra.

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.
