Amazon Dwarf Squirrel

The Amazon Dwarf Squirrel (Microsciurus flaviventer) is a species in the genus Microsciurus. Its conservation status is listed as Data Deficient, indicating insufficient data for assessment. Typically found in diverse terrestrial and aquatic ecosystems.

Common Porecrust

The Common Porecrust, <em>Schizophyllum commune</em>, is one of the most widely distributed fungi on Earth, belonging to the family Schizophyllaceae within the order Agaricales. It is a wood-decay bracket fungus found on dead and dying hardwood trees, logs, and stumps across virtually every vegetated continent, including Africa, Asia, Europe, and the Americas. The species is readily identified by its small, fan-shaped to lobed, hairy gray-white fruiting bodies and its distinctive split gill-like structures on the underside, which give it the common name split-gill fungus. <em>Schizophyllum commune</em> typically fruits year-round in humid conditions and is capable of surviving extreme desiccation, reviving when moisture returns. It plays an important ecological role as a saprotrophic decomposer of lignocellulosic material, contributing to nutrient cycling in forest ecosystems. The species is also notable as an opportunistic pathogen in immunocompromised humans, occasionally causing pulmonary or sinus infections. It is assessed as Least Concern on the IUCN Red List owing to its vast range and abundance. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
