aveia

<em>Avena fatua</em>, commonly known as common wild oats or wild oats, is a widely distributed annual grass in the family Poaceae, classified as Least Concern by the IUCN. It occurs globally across temperate and subtropical regions, including agricultural landscapes in Europe, Asia, the Americas, Africa, and Australia, where it is both a native species in parts of Eurasia and a naturalized weed elsewhere. The species typically grows in cultivated fields, disturbed ground, roadsides, and waste places, and is one of the most economically significant agricultural weeds worldwide, competing with crops such as wheat and barley. <em>Avena fatua</em> resembles cultivated oat but is distinguished by its strongly twisted and bent awns, which are hygroscopically sensitive and aid in seed dispersal by anchoring seeds into soil as they twist in response to changes in humidity. The plant typically reaches 60–120 cm in height and produces open, drooping panicles. It completes its life cycle in a single growing season, producing abundant seeds that can remain viable in the soil seed bank for many years. Biological traits including average lifespan as an annual, precise biomass per plant, and root depth remain poorly documented in standardized databases. Ecologically, common wild oats provides seed resources for granivorous birds and rodents, though its competitive nature in agricultural settings makes it a primary target for weed management programs globally.

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.
