Columbia sedge

<em>Carex aperta</em>, the Columbia sedge, is a perennial sedge in the family Cyperaceae native to Canada, where it occurs in grasslands, wetlands, riparian forests, and cultivated landscapes. This species is assessed as Least Concern by the IUCN. Columbia sedge typically inhabits moist to wet habitats including stream banks, lake shores, and seasonally flooded meadows within its Canadian range, where it often forms part of the emergent or shoreline vegetation community. Like other members of the genus <em>Carex</em>, this species is wind-pollinated and produces small, nut-like fruits enclosed within specialised sac-like structures called perigynia, features that facilitate taxonomic identification. Sedges in riparian and wetland ecosystems perform important ecological functions including bank stabilisation through rhizome networks, provision of nesting material and cover for waterfowl and small mammals, and contribution to organic matter accumulation in wetland soils. <em>Carex aperta</em> is adapted to fine-textured, moisture-retentive soils and may tolerate seasonal inundation. Its distribution in Canada spans portions of British Columbia and adjacent provinces within moist temperate forest zones. Biological traits of this species remain poorly documented in the scientific literature.

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.
