Schwarzschnabel-Schnäppertyrann

The Black-billed Flycatcher (Aphanotriccus audax) is a species in the genus Aphanotriccus. It is currently classified as Near Threatened on the IUCN Red List. Inhabits tropical and subtropical moist broadleaf forests and tropical and subtropical dry broadleaf forests within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Colchicum Rust

<em>Uromyces colchici</em>, commonly referred to as Colchicum Rust, is a fungal pathogen in the order Pucciniales, family Pucciniaceae. This rust fungus is associated with plants in the genus <em>Colchicum</em>, commonly known as autumn crocuses or meadow saffrons. The species has been recorded in the United Kingdom and is presumed to occupy European ecosystems more broadly. Rust fungi in the genus <em>Uromyces</em> are obligate biotrophs, meaning they complete their life cycles on living host plant tissue. They typically cause visible lesions or pustules on leaves and stems of their host plants, which can affect host vigor. <em>Uromyces colchici</em> has not been formally assessed under the IUCN Red List, and its conservation status is unknown. Biological traits such as reproductive specifics and dispersal mechanisms follow those typical of rust fungi but have not been specifically documented for this species in available records. Biological traits of this species remain poorly documented in the scientific literature. Its ecological impact on <em>Colchicum</em> populations in European grassland and woodland habitats is not well quantified.
