Azorean predacious diving beetle

The Azorean predacious diving beetle (Agabus godmanni) is a species in the genus Agabus. It is currently classified as Endangered on the IUCN Red List. Typically found in virtually all terrestrial and freshwater habitats.

Common Gold-Dust

<em>Chrysothrix xanthina</em>, commonly known as common gold-dust, is a crustose lichen in the family Chrysotrichaceae. The species has been documented in Brazil, Colombia, and the United States, indicating a distribution across parts of South and North America. Lichens in the genus <em>Chrysothrix</em> are characterized by their powdery, brightly colored thallus, and <em>C. xanthina</em> is typically recognized by its distinctive yellow-gold granular coating on its substrate, produced by pigments including calycin and vulpinic acid. <em>Chrysothrix xanthina</em> typically grows on the bark of trees and occasionally on rock surfaces in humid forest and woodland habitats, where it forms conspicuous yellow patches. The species is not currently evaluated for conservation status. Biological traits of this species remain poorly documented in the scientific literature. As a lichen, <em>Chrysothrix xanthina</em> represents a symbiotic association between a fungal partner (mycobiont) and one or more photosynthetic partners (algae or cyanobacteria), and contributes to nutrient cycling and substrate weathering in the ecosystems it inhabits.
