Blue-fronted Parrot / Turquoise-fronted Amazon

One of the most popular pet parrots in the world after the budgerigar and African grey, blue-fronted amazons are recognized by their bright yellow face with blue forehead and red-orange shoulder patches. Native to central South America in Brazil, Bolivia, Paraguay, and Argentina, they inhabit forest, woodland, and palm groves. Highly intelligent with strong mimicry and speech abilities, they have been kept as pets since the 1700s. Wild populations face pressure from trapping.

Common Tarcrust

<em>Diatrype stigma</em>, the common tarcrust, is a saprotrophic fungus in the family Diatrypaceae, found across Belgium, Denmark, Norway, Portugal, and Sweden, as well as more broadly in Europe and temperate regions globally. It grows as a crust-like, charcoal-black stromata on the dead bark and branches of deciduous hardwoods, particularly hazel, beech, and alder. The fruiting bodies are typically flat to slightly raised, dark gray to black patches that contain numerous embedded perithecia in which ascospores are produced. This fungus plays an important ecological role as a decomposer, breaking down dead woody material and recycling nutrients in forest ecosystems. It is Not Evaluated on the IUCN Red List; given its broad distribution on common substrates, it is generally considered widespread. The species reproduces via wind-dispersed ascospores released from the perithecia. Diet, as a saprotrophic organism, consists of dead organic woody matter. Biological traits such as colony growth rates, spore output, and longevity remain poorly documented in standardized quantitative assessments.
