Black-throated Mango

A large, striking hummingbird of tropical forests from southern Mexico to Argentina, black-throated mangos have dramatic sexual dimorphism — males display glittering black throat and breast with violet and green flanks and a bold purple tail, while females are white below with a central black stripe. Inhabiting forest edges, clearings, and gardens, they aggressively defend flowering trees. Males perform spectacular aerial display flights at treetop height. Listed as Least Concern across their broad neotropical range.

Compressed Flapwort

<em>Nardia compressa</em>, commonly called the Compressed Flapwort, is a leafy liverwort in the family Jungermanniaceae, a lineage of non-vascular land plants (division Marchantiophyta) that diverged from other embryophytes over 400 million years ago. This small, mat-forming bryophyte typically colonizes moist, acidic substrates along stream banks, seepages, and wet rock faces in cool-temperate habitats throughout Europe. Its flattened, overlapping leaves give the plant a compressed appearance, which inspired both its common and scientific names. Like all liverworts, <em>Nardia compressa</em> lacks true vascular tissue and absorbs water and nutrients directly through its leaf surfaces, deriving energy through photosynthesis rather than heterotrophic feeding. The species has been recorded in Belgium, Norway, and Sweden, suggesting an affinity for the moist, boreal and Atlantic climatic zones of northwestern and northern Europe. It is currently assessed as Least Concern by the IUCN, indicating no immediate extinction risk across its known range. Biological traits including individual lifespan, reproductive rates, and specific growth measurements remain poorly documented relative to vascular plant species, though liverworts are generally slow-growing perennial organisms tightly dependent on stable moisture regimes.
