Found in Ecuador. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Club Grain-Spored Lichen

Sarcogyne clavus is a crustose lichen in the family Acarosporaceae, forming closely appressed, granular to warty grey-white thalli on calcareous rocks, concrete, mortar, and exposed mineral substrates. The species is characterized by its distinctive club-shaped or clavate ascospores, from which its specific name derives. Like other Sarcogyne species, it produces apothecia that are typically lecideine (lacking a thalline margin), dark-colored, and often somewhat convex. This lichen favors exposed, sunny rock faces with high calcium content, including limestone outcrops, old walls, and stone monuments. S. clavus is distributed across Europe and North America, occurring primarily in calcareous rock habitats. As a pioneer colonizer of bare rock, it contributes to the initial stages of ecological succession by weathering the substrate and accumulating organic matter. The IUCN lists this species as Data Deficient, reflecting insufficient data on its population size, distribution, and ecology to assess its conservation status with confidence. Lichens as a group are sensitive to air pollution, but calcicolous crustose lichens on exposed rock may be less vulnerable than foliose or fruticose species.

Giraffe

The tallest living animal on Earth, giraffes can reach 5.5 meters in height and weigh up to 1,750 kg. Their elongated necks — containing the same seven cervical vertebrae as all mammals — evolved for feeding on acacia trees in African savannas and woodlands. Social animals living in loose herds with no permanent bonds, giraffes communicate through infrasound and body language. Vulnerable, with populations declining due to habitat loss and poaching.
