cavalinha

<em>Equisetum hyemale</em>, the common scouring rush, is a vascular plant in the family Equisetaceae, order Equisetales, representing one of the ancient lineages of spore-bearing plants with relatives dating to the Carboniferous period. This species has a broad distribution across Europe, North America, and parts of Asia, typically growing in moist, disturbed habitats such as stream banks, wet roadsides, and woodland margins. The stems of <em>Equisetum hyemale</em> are characteristically jointed, hollow, and rough-textured due to silica deposits in the outer tissue — a trait historically exploited for scouring and polishing. Unlike flowering plants, it reproduces via spores produced at terminal strobili rather than seeds. Despite its wide range, <em>Equisetum hyemale</em> is currently classified as Near Threatened by the IUCN, reflecting concern over population declines linked to wetland drainage, habitat modification, and changing hydrology across portions of its European range. Conservation measures focused on wetland and riparian habitat protection are important for the species' long-term persistence. Biological traits for this species remain poorly documented in the scientific literature, including detailed data on lifespan, growth dimensions, and dietary ecology.

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.
