Common Orange Legionnaire

<em>Beris vallata</em> is a soldier fly in the family Stratiomyidae, known from Belgium, Denmark, Norway, and Sweden in northern Europe. The species inhabits a broad range of terrestrial and freshwater environments, including woodland edges, hedgerows, stream margins, and moist meadows where decaying organic matter supports larval development. Larvae of Beris species typically develop in rotting wood, leaf litter, damp soil, or organic debris, while adults are often found visiting flowers for nectar and pollen. The IUCN classifies this species as Near Threatened, indicating that it faces meaningful risk factors that could elevate its status if current trends continue. Pressures likely include habitat degradation, loss of traditional woodland management practices, and the decline of dead wood microhabitats essential for larval stages. The species has a restricted distribution confined to northern European countries and may be sensitive to changes in woodland structure and composition. Biological traits such as average lifespan, body length, body weight, and detailed dietary studies remain poorly documented in standardized ecological databases for this dipteran species. Continued monitoring of woodland habitats across its range is important for its long-term conservation.

koala

Icónico marsupial del este y sureste de Australia, los koalas pesan hasta 15 kg y pasan hasta 22 horas diarias durmiendo para conservar energía de su dieta de hojas de eucalipto, baja en calorías. Altamente especializados para procesar los compuestos tóxicos del eucalipto que matarían a la mayoría de los demás mamíferos, poseen microbiomas intestinales únicamente adaptados para la desintoxicación. Clasificado como En Peligro en 2022, con poblaciones diezmadas por la enfermedad de clamidia, la deforestación y el cambio climático.
