Common Rim Lichen

<em>Lecanora pulicaris</em>, the common rim lichen, is a crustose lichen in the family Lecanoraceae, order Lecanorales, within the kingdom Fungi (as the mycobiont component). It is distributed across temperate and boreal zones, with documented records from Denmark, Norway, Portugal, Sweden, and the United States. The species is assessed as Least Concern on the IUCN Red List, reflecting its widespread occurrence on bark of deciduous and coniferous trees across the Northern Hemisphere. Rim lichens in the genus Lecanora are characterized by their apothecia — disc-shaped reproductive structures rimmed by a thallus margin — which give the genus its common name. <em>Lecanora pulicaris</em> typically forms pale gray-green crustose patches on smooth to moderately rough bark surfaces, particularly favoring the bark of birch, alder, and other hardwood trees in well-lit forest and woodland environments. As a lichen, it is a symbiotic organism comprising a fungal partner (mycobiont) and photosynthetic algal or cyanobacterial partners (photobionts), deriving nutrients through photosynthesis and mineral absorption from the substrate. Biological traits such as lifespan and growth rates remain poorly documented for this taxon, though crustose lichens typically grow very slowly. It serves as a bioindicator of air quality in temperate forests.

Onca

O maior felino das Américas, atingindo até 100 kg com corpo robusto e musculoso e pelagem com padrão de rosetas característico. Encontrado do México até a América do Sul, com populações mais expressivas na Amazônia e no Pantanal. Nadadores poderosos e predadores de topo, os jaguares desempenham papel fundamental na regulação das populações de presas. Classificado como Quase Ameaçado, com sua área de ocorrência diminuindo devido ao desmatamento.
